Devices for treating and/or conveying a strip of material

The invention relates to devices for processing and / or conveying a web according to claim 1, 2 or 10.

EP 12 38 935 A2 discloses a device for longitudinally cutting films and strips, wherein an upper knife can be positioned for setting a cutting width transversely to the direction of transport of the web.

A roller changer is known from DE 101 50 810 A1, wherein two roller arms for receiving a roller form a pair and can be moved individually one by one along a rotational axis of the roller.

DE 196 02 248 A1 discloses a former which can be moved along an inlet gap of two successive rollers for the lateral correction of the folded strand.

WO 01/70608 A1 discloses a reversible rod which can be positioned transversely to the feed direction of the web and a register roller which can be positioned longitudinally to the inlet light of the web. The reversible rod is pivotable in such a way that, depending on the position, it deflects the path to the right or left.

DE 36 14 981 C2 discloses two web edge sensors, each of which has a drive and is controlled by a common control device. DE 35 33 274 C3 discloses the like.

DE 195 40 164 C1 shows a transport device with two conveyor devices arranged next to one another for endless material, each device having an axially movable feed device.

A device with which it is possible to cut two partial webs or three partial webs of variable width from a running paper web of maximum width and to fold these partial webs is known from DE 42 04 254 A1. The apparatus shown there comprises three former hoppers arranged in two planes, wherein two former hoppers adjacent in a first plane are displaceable transversely with respect to the direction of travel of the paper web, in order to selectively fold both partial webs of a two-sectioned paper web or to fold the two outer partial webs of a three- Train to serve. An adaptation of other web-guiding devices than the former to the respective web width is not provided.

From DE 43 11 437 A1, a winding rod arrangement is known whose umbilical rods can be folded in order to offset a web applied to them by their width to the left or to the right depending on the position of the turning bars. This reversing rod arrangement can not be easily combined with the device from DE 42 04 254 A1, since a three-dimensionally divided partial web which is displaced for example by half a web width does not meet the folding funnel intended for it.

DE 100 03 025 C1 discloses a device for processing a web with at least one former and a knife arranged thereon as a knife, the knife and the former being movable through a common actuator transversely to the direction of travel of the web.

In US Pat. No. 3,744,487, web processing or guide elements, which are designed as reversing rods, as a longitudinal cutting knife and as a register roll, are disclosed, which can be pre-positioned by means of individual drives with regard to planned productions.

EP 0 457 304 A1 relates to a mechanism with two processing elements, which are movable mutually by a common drive, of a device for folding pockets.

The object of the invention is to provide devices for processing and / or conveying a web.

This object is achieved according to the invention by the features of claim 1, 2 or 10.

A substantial advantage which can be achieved with the device or the method is, on the one hand, the fact that a long-lasting adjustment is not required at the start of production. In contrast to settings, which occur only during the pressure recording by means of control circuits, the amount of waste can be significantly reduced.

A particular advantage of the invention is that it allows rapid adaptation to a change in the web widths to be processed because a user does not need to access each individual web processing tool to be moved to match the web width.

A further time saving results when the control unit itself is set up to automatically calculate and adjust the positions of the different processing tools, which are necessarily correlated with one another, from a small number of input parameters. In the simplest case, it is sufficient to calculate these positions merely to specify the width of a web to be processed; The control unit can easily determine from this presetting the required positions of all the machining tools provided that a reference line of all the paths to be processed, for example a right or left edge, or preferably the center line, is the same regardless of its width in the device Position.

Since the displacements of some web processing tools necessary for adaptation to a changed web width are firmly correlated, the device can be simplified by using an actuator for displacing a plurality of web processing tools at the same time.

The web processing tools of the device according to the invention include, for example, at least one former. With a suitable choice of the reference line it can be sufficient if only one of two folders is displaceable; However, it is preferred, if preferred, to select the center line of the web to be processed as a reference line, at least both of two folding funnels arranged next to one another must be displaceable.

In order to produce a plurality of partial webs from a single initial web in the device according to the invention, which partial webs can then be fed to individual folders, the device according to the invention advantageously comprises at least one knife for longitudinally cutting the initial web into partial webs. If more than one such blade is present, at least one of them must be displaceable.

The apparatus may further comprise at least one interval cutting knife for longitudinally cutting the material web sideways. If the material web is a printed paper web, in particular a newspaper, such an interval cutting knife can be used to cut the web locally at the height of each second side, for example, a broadsheet signature with a tabloid insert to produce.

It is also advantageous if the device has a longitudinal cutting device with at least one knife, which is also preset transversely to the direction of travel of the web, in order to establish the cutting line for the partial webs to be produced.

If a starting web cut into several partial webs is processed in the apparatus, pulling or catching rollers are appropriately assigned as web processing tools to each of the partial webs. It is therefore desirable that such rollers are also automatically positionable by the control unit according to the width of the output web to be processed and the number of partial webs.

Also, turning bars can be provided as machining tools displaceable by the control unit. As processing tools, here as well as in the following, web guiding, web driving and / or web guiding elements such as, for example, winding rods, pressure rollers and / or guide rollers are understood.

For driving the displacement of the machining tools, the actuators preferably each have a threaded spindle, and the displaceable machining tool each have a sliding block which is engaged with such a threaded spindle.

Advantageously, such a threaded spindle can have a plurality of sections which differ in pitch and / or pitch, and the sliding blocks of a plurality of machining tools of the same type are respectively engaged with the various sections of a same spindle to couple the machining tools but possibly in different directions and / Or to move speeds.

Exemplary embodiments of the invention are illustrated in the drawings and are described in more detail below.

FIG. 1a shows a former arrangement in which two paper partitions 01, 02 are guided side by side via a roller 03 and then into two former funnels 06, 07. The former funnels 06, 07 are mounted so as to be displaceable in a frame 04 parallel to the axis of the roller 03. An actuating member for displacing the folding funnel 06, 07 is formed by a threaded spindle 08, which is parallel to the axis of the roller 03 and has two sections with the same pitch, and a drive 11, for example an electric motor 11, for rotationally driving the threaded spindle 08 The drive 11 and the feed drum 06; 07 can also be designed in a different way. The folding funnels 06, 07 are each provided with a sliding block 09, the two sliding blocks 09 being in engagement with different sections of the threaded spindle 08, So that a rotation of the thread spindle 08 drives the formers 06, 07 to opposing movements. An electronic control unit 10 or a system S for presetting the system S below controls the electric motor 11 on the basis of a width of the paper webs 01, 02 entered by the user on the control unit 10 (or the system S). The information on the width can be fed to the control device 10 Or system S) can also be implemented in a different way, for example by reading in a common value or a value which is provided in a product planning system, a machine control, an imposition scheme and / or a control console (indicated by P in FIG.

A frame 15 or frame 15 connected to the left former 06 serves simultaneously as a support for a bearing of the roller 03, so that the roller 03 follows each movement of the former 06. The right side of the roller 03 can be displaced telescopically on a pin which is fixed to the frame 04, for example by means of an axially displaceable bearing 25 (FIG. 1 b ). When the former is displaced, the roller 03 and, for example, a groove 20 (dashed in FIG. 1 b) rotating on the roller 03, which cooperates with a knife for the continuous or discontinuous longitudinal section as a cutting groove.

An interval cutting knife 05 or a skip slitter 05, which is mounted above the roll 03, is also rigidly connected to the former 06, for example, via the frame 15. The intermittent cutting knife 05 has a rotating interrupted blade which is aligned with the fold line of the former 06 and alternately intersects one pair of pairs of printed pages alternately printed on the paper part 01 and leaves the other uncut. If the uncut side pairs are broadsheet pages with lines oriented transversely to the direction of conveyance and, in the case of the tabloid pages cut, the lines of which are oriented in the conveying direction, the paper web 01 can be fed in a connected,

FIG. 1b shows the adjustment of the formers 06, 07 for the processing of two paper partitions 12, 13, which are narrower by a value d compared to the paper part paths 01, 02 of FIG. The center line M, on which the tracks 12, 13 touch, has the same position as the center line M between the tracks 01, 02 in FIG. 1a with respect to the frame. The thread spindle 08 is rotated by means of the electric motor 11 for the adjustment of the folding funnels 06, 07 for the machining of such narrow paper partial webs 12, 13 so that the former funnels 06, 07 are shifted by d / 2 towards the center line M.

In an advantageous modification or further development, the folding funnel 06; 07 - in addition or instead of the connection to the knife 05 - a driven roller 30 arranged downstream of the funnel tip, together or simultaneously with the former 06; 07 can be moved laterally. For this purpose, the former 06; 07 is preferably connected to a bearing of the roller 30 via a common frame 15. When the former 06, 07 is displaced, the roller 30 is simultaneously moved. The roller 30 is designed either as a driven transfer roller 30, by means of which a guide roller 30; 07 and a directional change is experienced. In another embodiment, the roller 30 can be designed as, for example, a single-motor driven tension roller 30 of a pulling roller group against which a pressing roller 35 can be set. In this case, the entire pulling group 30, 35 with the former 06; 07.

Of course, a folder arrangement of the type shown in FIGS. 1 a, 1 b could also have three or more folders for processing a corresponding number of partial webs. When three parallel partial webs have to be processed and their center line M is always the same in relation to the frame, regardless of the width of the webs, the two outer folders must be displaced by d each time the width of the partial webs is changed by d The middle former remains unchanged. In the case of four partial paths, the displacement d / 2 for the two middle and 3d / 2 for the two outer, etc.

In an advantageous embodiment, it is provided for the presetting of the printing machine (see FIG. 9) that the control 10 or the drive 11 for the described movement of the former 06; 07 is in signal connection with the system S. On the basis of the production data (eg, the web or partial web width b; b '), the current position of the former 06; 07 is compared with a position which is predetermined or predeterminable for this production and, if appropriate, causes a corresponding movement via actuating commands to the relevant drive 11. Depending on the width of the web or partial web and / or its center, the former 06; 07 (or funnel tip) correspondingly laterally. The former 06; 07 is, for example, positioned in such a way that the partial web 02; 05 centrally with respect to the funnel tip on the relevant former 06; 07.

FIG. 2a shows a trapping roller arrangement as a further example of web processing tools of a device according to the invention. This catch roller arrangement consists of a roller 14, which is surrounded by a paper web to be caught, not shown in the figure, several rollers 16, several sliding blocks 18, 19, 21, a guide rail 17, a threaded spindle 22, (Or system S) controlled electric motor.

The roller 14 is rotatably mounted in the frame 04. The guide rail 17 is mounted in the frame 04 parallel to the roller 14. A plurality of sliding blocks 18, 19 are arranged displaceably on the guide rail 17. A sliding block 21 arranged centrally to the roller 14 is fixedly arranged on the guide rail 17. The sliding blocks 18, 19 and 21 each carry a rotatably mounted roller 16. The rollers 16 press against the roller 14 and roll against it. Since the rollers 16 are designed to be rotatable only in one direction, they prevent the paper web wound around the roller 14 from falling back in the event of a paper web break.

The thread spindle 22 pierces the frame 04 on one side and projects out of the frame 04 at this point. In this case, it is aligned parallel to the roller 14 and to the guide rail 17. The threaded spindle 22 has two different threaded sections with a different rotational sense, which are separated from one another by a threaded section. The sliding block 21 is arranged on this helical section. The two threaded sections have slopes which increase along a longitudinal axis of the threaded spindle 22 in proportion to the distance from the sliding block 21. The sliding blocks 18, 19 are not in engagement with the left or right threaded section viewed from the sliding block 21, for example, by means of an internal thread with a plurality of windings - which would remain stuck due to the variability of the pitch,

If the illustrated catch roller arrangement is to be used for a paper web of narrower width, the sliding blocks 18, 19 are displaced along the guide rail 17, as shown in FIG. 2b. The threaded spindle 22 is rotated via the drive 23. As a result of the different rotation of the two threaded sections, which are engaged with the sliding blocks 18 and 19, the sliding blocks 18 move from the left and the sliding blocks 19 toward the central sliding block 21 from the right when the threaded spindle 22 is rotated. The movement of the sliding blocks 18, 19 takes place synchronously, but due to the inclinations of the threaded sections which are along the longitudinal axis of the threaded spindle 22, the paths which the sliding blocks 18, 19, and thus the rollers 16 guided by them, Is proportional to the distance between the middle sliding block 21. Depending on the width of the paper web to be processed, the sliding blocks 18, 19 can be displaced more or less closely to the sliding block 21 by means of a corresponding rotation of the threaded spindle 22 and thus set the catch roller for any paper web widths. The sliding blocks 18, 19 can be arbitrarily placed on the spindle 22 before displacement; The ratio of their distances is retained during a displacement. 19 can be arbitrarily placed on the spindle 22 before displacement; The ratio of their distances is retained during a displacement. 19 can be arbitrarily placed on the spindle 22 before displacement; The ratio of their distances is retained during a displacement.

It would also be conceivable to provide two threaded sections each with a constant slope over their entire length. This is sufficient for a roller arrangement with no more than three displaceable rollers 16. In the case of a larger roller number, as shown in FIG. 2b, the distance between the two left sliding blocks 18 (and also between the right sliding blocks 19) Remain constant and distance ratios would change with a shift.

Another possibility would be to provide for each individual one of the four sliding blocks 18, 19 a separate threaded section with a specific pitch. The variability of the web widths to which the catch roller arrangement is adjustable is, however, limited by the fact that the sliding blocks, at least those which are coupled to the spindle via an internal thread with several windings, can not leave the thread sections with the pitch fitting for their thread ,

It is also possible to provide a plurality of threaded spindles, each with two sections of oppositely equal pitch, each of which carries sliding blocks of mutually opposite rollers with respect to the center line M. These threaded spindles are expediently identical to one another. In order to achieve different displacements of the rollers coupled to them, the threaded spindles can be driven by a common electric motor via a gear with a respective adapted transmission ratio, or each threaded spindle has its own electric motor, which is individually controlled by the control unit in accordance with the required displacement.

In the manner described above, it is also possible to adjust the tension roller arrangements for paper webs to be processed with different widths, since pull roller arrangements have in principle a structure which is analogous to catch roller arrangements. Such presetting values ​​can be stored in tabular form for the various productions, or a calculation is carried out in the system S using the lateral offset to be obtained by the web widths.

3a shows a longitudinal cutting device 71 of a superstructure 67 (FIG. 9). The longitudinal cutting device 71 is designed to cut an incoming web longitudinally into a plurality of partial webs, for example, two partial webs. Two guide rails 24 are arranged parallel in the frame 04. A paper web 26 is guided between the two guide rails 24. Two carriages 27 are held displaceably on the two guide rails 24. They are designed and assembled in mirror image. Each carriage 27 carries a rotating knife 28 with a cutting edge oriented perpendicular to the paper web 26 and a counterpressure roller 29 (counter blade) cooperating with the knife 28. Between the carriages 27 there is a further knife 32 which is also perpendicular to the paper web 26, And a counter-pressure roller 31 cooperating therewith. The paper web 26 is cut into four partial webs by the knives 28, 32 and counter-pressure rollers 29, 31. A threaded spindle 33 parallel to the guide rails 24 has two threaded sections with different rotations and the same pitch, each of which is engaged with one of the carriages 27. One end portion of the threaded spindle 33 projects out of the rack 04 on one side. At this end portion, a drive 34, for example, an electric motor 34, is provided for rotationally driving the threaded spindle 33. The individual knives 28; 32 or counter-knives can also be drivable together by means of a different drive 34 or by individual drives per knife or pair of knives. 31 in four partial paths. A threaded spindle 33 parallel to the guide rails 24 has two threaded sections with different rotations and the same pitch, each of which is engaged with one of the carriages 27. One end portion of the threaded spindle 33 projects out of the rack 04 on one side. At this end portion, a drive 34, for example, an electric motor 34, is provided for rotationally driving the threaded spindle 33. The individual knives 28; 32 or counter-knives can also be drivable together by means of a different drive 34 or by individual drives per knife or pair of knives. 31 in four partial paths. A threaded spindle 33 parallel to the guide rails 24 has two threaded sections with different rotations and the same pitch, each of which is engaged with one of the carriages 27. One end portion of the threaded spindle 33 projects out of the rack 04 on one side. At this end portion, a drive 34, for example, an electric motor 34, is provided for rotationally driving the threaded spindle 33. The individual knives 28; 32 or counter-knives can also be drivable together by means of a different drive 34 or by individual drives per knife or pair of knives. One end portion of the threaded spindle 33 projects out of the rack 04 on one side. At this end portion, a drive 34, for example, an electric motor 34, is provided for rotationally driving the threaded spindle 33. The individual knives 28; 32 or counter-knives can also be drivable together by means of a different drive 34 or by individual drives per knife or pair of knives. One end portion of the threaded spindle 33 projects out of the rack 04 on one side. At this end portion, a drive 34, for example, an electric motor 34, is provided for rotationally driving the threaded spindle 33. The individual knives 28; 32 or counter-knives can also be drivable together by means of a different drive 34 or by individual drives per knife or pair of knives.

If the described longitudinal cutting device is to cut a paper web 36 of narrow width into four partial webs, the thread spindle 33 is rotated by the electric motor 34, as shown in FIG. 3b. Since the carriages 27 are engaged on different threaded sections of the threaded spindle 33 with different rotational speeds and the same pitch, the twisting of the threaded spindle 33 causes the carriages 27 to move towards one another or onto the central knife 32, respectively. The twisting of the threaded spindle 33 is continued until the distance between two knives 28, 32 corresponds to a quarter of the width of the narrow paper web 36.

The operation of the motor 34 is controlled by the control unit 10 (or system S) (FIG. 1a), which determines the positions of the knives 28 on the basis of a width, which is automatically determined by the user or by sensors (not shown) Path or the partial webs resulting from the cutting.

In the case of a plurality of measuring units (pairs of knives 28, 32 and counter-knives 29), for example, all of them can be individually driven and / or individually switched on / off.

The axial positioning or at least presetting of the machine control is preferably carried out automatically automatically on the basis of the width of the web intended for printing and the cutting lines to be produced specifically for the product, or by means of a control panel. For this purpose, for example, before the production start of the system S (from the machine control or a corresponding software program), the current setting for the presetting values ​​required for the planned production is checked and / or a presetting is made by acting on the drive 34 (or the drives 34). Such presetting values ​​can be stored in tabular form for the various productions, or a calculation is carried out in the system S using the lateral offset to be obtained by the web widths.

In FIG. 4a, a wend deck with two crossed reversing bars 37, 38 is shown as a further example of web processing tools which may be present in the device. Two pairs of guide rails 39, 41, referred to as front and rear guide rails 39, are held between plates of the frame 04. Only one upper guide rail can be seen in the figure of each pair of guide rails 39, 41 since it obscures the underlying rail which is parallel to it. A sliding block 42, 43 is provided at the ends of the reversible rod 37, the sliding block 42 being slidably arranged on the visible upper guide rail 39 of the rear guide rail pair and the sliding block 43 being arranged on the visible upper guide rail 41 of the front guide rail pair.

A deflection roller 47 is arranged rotatably in the frame 04 between the guide rail pairs 39 and 41 and transversely thereto.

A paper web 51 running perpendicularly to the guide rail pairs 39 and 41 revolves around the inclined turning rod 37 and thereby changes its direction of travel by 90 °. It wraps around the deflection roller 47 and runs back from it and over the obliquely positioned reversing rod 38, which is crossed with the turning rod 37, whereby its direction of travel changes by 90 °, so that it has returned to its original direction of travel after leaving the reversing surface Is offset by exactly one paper web width and is used.

A pair of threaded spindles 48 parallel to the guide rails 39, 41, of which a lower threaded spindle 48 is concealed in the figure by the upper threaded spindle 48, are rotatably held in the frame 04. A drive 49, for example an electric motor 49, engages at one end portion of each spindle 48.

If the described arrangement is to be used for a paper web 52 with a smaller width as shown in FIG. 4b, on the one hand the distance of the turning bars 37 and 38 must be changed in order to achieve an offset of exactly one web width. For this purpose, the control unit 10 (or system S) (not shown in the FIGURE) controls an opposing movement of the motors 49 and thus of the reversing rods 37, 38. On the other hand, in particular when more than two partial paths have to be processed Of the turning bars 37, 38 may be required to ensure that the partial webs do not come too close to the ends of the turning bars 37, For this purpose, the control unit 10 (or system S) respectively drives the motors 49 in a similar manner.

The Wenddeck described above is shown in FIG. 5a after a conversion. In this embodiment, the turntables 37 and 38 are slidably arranged parallel to one another with the sliding blocks 42, 43, 44, 46 on the guide rails of the guide rail pairs 39 and 41.

A paper web 53 to be offset runs perpendicularly to the guide rail pairs 39 and 41 into the winding top, wraps successively the reversing rod 37 and the reversing rod 38, and leaves the winding blank laterally offset by a width of the paper web without being used.

4a, 4b, on the one hand, the control unit 10 (or system S), on the one hand, adjusts the reversing bars 37, 38 on the other side of the paper web 54 (FIG. 5b), which has a width less than the path 53, So that the distance of the turning bars is adapted to the changed web width and, if necessary, displaces both turning bars 37, 38 in the same direction so that the web 54 is sufficiently centered on the turning bars.

FIG. 6 shows an advantageous embodiment of the winding rod arrangement according to FIG. 4, whereby the arrangement, however, comprises only one carrier 39; 41 for the two turning bars 37, 38. The sliding blocks 43; 46 slide on the same carrier 39; 41 and are driven by means of a common threaded spindle 48, which has two opposing threads for one of the sliding blocks in each case. The spindle is driven by the motor 49, wherein, upon rotation of the thread spindle, the sliding blocks 43; 46 in opposite directions.

FIG. 7 also shows an advantageous embodiment of the arrangement according to FIG. 5, wherein here, as in FIG. 6, a common thread spindle 48 with counter-rotating threads for the sliding blocks 43; 46 is provided. The sliding blocks 43; 46 also run on the same carrier 41. Driving the threaded spindle 48 by the common motor 49 causes a counter-rotating movement of the two turning bars 37; 38 with their sliding blocks 43; 46.

A reversing mechanism 72 of a printing machine (FIG. 9) has at least one winding end with two mutually associated winding rods 37; 38, by means of which a partial web 51 to 54 can be brought into a different flight and / or overturned. It includes a pair of reversing rods 37; 38. In an advantageous embodiment, which is not shown here, two winding segments, ie two pairs of winding rods 37; 38 are provided for the displacement or the falling of two partial webs 51 to 54. The turning bars 37; 38 of a pair can either be arranged parallel to each other and inclined by 45 ° against the incoming web (offset), or they are arranged perpendicular to one another and inclined by 45 ° or 135 ° against the incoming web (falls and possibly offset) ).

In an advantageous embodiment, all the convertible rods 37; 38 are designed such that they can be tilted or tilted by 90 ° in the plane of the respective incoming web. In a variant to FIGS. 4 and 5, a flying bearing of the turning rods 37; 38, ie with a fixed end and a free end. In this case, the carriers 39 are omitted. In a further development, the winding rods 37; 38 are each assigned a means (not shown) which detects the actual position of the turning rod 37; 38 - tilted to the left or to the right - and signals it to the machine control or the control station of the machine or the system S. These may, for example, be initiators which are activated or deactivated mechanically (switch) or electromagnetic (induction, light barrier) as soon as the reversing rod 37; 38 is located in one of the provided positions. The printer or a program can then check whether the turning bars 37; 38 in the position required for the planned production. An error signal can be output by the system S when the position of the reversing rod 37; 38 does not correspond to the intended production (or web run).

Each turn rod 37; 38 is arranged as shown above in a preferred embodiment as a whole in a direction transverse to the incoming web in the superstructure 67. This is the reversing rod 37; 38 adapted to a product or a web run or web width by means of the drive 49.

For the presetting of the printing press, it is advantageously provided that the drives 49 of the reversing rods 37; 38 are in signal connection with the system S. On the basis of the production data (eg, provided web guidance, resulting theoretical cutting line, and / or web or partial web width), the actual position of the turning rod 37; 38 is compared with a position predefined or predeterminable for this production and, if appropriate, causes a corresponding movement via positioning commands to the respective drives 49. Such presetting values ​​can be stored in tabular form for the various productions, or a calculation is carried out in the system S using the lateral offset to be obtained by the web widths.

In a further development of the superstructure 67, the pivotable turning rods 37; 38 is assigned a drive (not shown) for the pivoting, which, for example, as set forth for the drives 49, is pre-set by the above-mentioned system S in accordance with the planned production and / or web guidance. Such a drive is advantageously designed, for example, as a cylinder which can be acted on by pressure medium and which is connected on one side to the frame and on the other to the turning rod 37; 38 outside its center of rotation.

FIG. 8 shows a schematic side view of the embodiment shown as a former 06; FIG. 07. The former 06; 07 is advantageously movable in a direction (at least one component) which is arranged perpendicularly to the backrest fold of the folding drum 06, (Transverse cutting cylinder, folding blade cylinder and / or folding jaw cylinder) of a downstream folding device 68 (see FIG. 9). With this, the correct inlet into the cylinders of the folding apparatus 68 can be adjusted for different web or strand widths and / or layers.

In an advantageous embodiment, it is provided for the presetting of the printing press that a drive (not shown) for the described movement of the former 06; 07 is in signal connection with a controller 10 or advantageously with the system S. On the basis of the production data (eg the web or sub-web width), the current position of the former 06; 07 is compared with a position which is predetermined or predeterminable for this production and, if appropriate, causes a corresponding movement via actuating commands to the relevant drive. Depending on the width of the web, partial web or strand, the former 06; 07 (or the funnel tip) accordingly. The former 06; 07 is positioned, for example, in such a way that the folded strand is appropriately dimensioned for each width - for example Essentially centrally on the lateral surface of the following cylinder - into the folding apparatus 68 or its conveying devices. Preset values ​​can be stored in tabular form for the various productions, or a calculation is made in the system by means of the path paths resulting from the web widths and the lateral offset.

The above-mentioned web processing tools are individually or several parts of a web-processing and / or processing machine, eg a printing machine (FIG. 9), in particular a web-fed rotary printing machine for printing one or more webs ; 62; 63; 64; 65; 66; 67; 68; 69 for supply, printing and further processing. The web B, in particular the paper web B to be covered, is unwound from, for example, a roll processing unit 61 before it is fed to one or more printing units 63 via a feed mechanism 62. Additional printing units 63 can be provided for the printing units 63 (eg four pieces for four-color printing) which are provided as standard for the multicolor printing, Which can then, for example, alternatively be used alternately to one or more of the remaining printing units 63 for the printing of printing plates. The printing units 63 can also be designed partly vertically one above the other as bridge printing units 63 or as (nine- or ten-cylinder) satellite printing units.

In one embodiment, a varnishing unit 64 can be provided in the web path.

After printing and, if necessary, painting, the web B passes through a drier 65, for example, and is optionally cooled again in a cooling unit 66 if the drying takes place in a thermal manner. After the dryer 65, in or after the cooling unit 66, at least one further conditioning device (not shown in FIG. 9), such as, for example, a coating device and / or re-moistening may be provided. After cooling and / or conditioning, the web B can be fed via a superstructure 67 to a folder 68. The superstructure 67 comprises, for example, a silicon plant, not shown in FIG. 1, the longitudinal cutting device 71 and a turning device 72 or a turning device 72 having at least one turning surface, as well as a turning device 06 or the folding funnel 06; 07. The said silicon plant can also be arranged in front of the superstructure 67, for example in the region of the cooling unit 66. The superstructure 67 can furthermore have a perforating unit (not shown in FIG. 9), a gluing unit, a numbering unit and / or a plowing rebate. After passing through the superstructure 67, the web B or partial webs B1; B2 into the folder 68.

In an advantageous embodiment, the printing machine additionally has a separate cross-cutter 69, for example a so-called planar cantilever 69, in which a web B, which is not guided by the folding apparatus 68, for example, is cut into format sheets and is stacked or laid.

The system S is preferably assigned to the machine for presetting, eg as an additional program in a machine control system and / or a planning system, which in logical signal connection to one or more of the above processing tools or units 61; 62; 63; 64; 65; 66; 67; 68; 69, in particular of the units 61; 63; 67.

In an advantageous further development, the elements of the roller changer 61 also fall under the above-mentioned web processing tools. For example, it is also advantageous for product changeover with one or more of the above-mentioned web processing tools to simultaneously adjust the lateral arms of the roller arms appropriately to the new width and / or position Of the train. The adjustment of the roll is, for example, useful when a sub-web is to be run in a different alignment through the printing press.

It is also advantageous if at the same time a lateral adjustment of cut register and / or color register measuring elements, eg heads, and / or a web edge control 57 are adapted in the axial direction to the new production, and / or an adjustment of the pressure rollers on the Pull roller below the funnel.

In the region of the folding apparatus, an adjustment of the paddle wheel in the exit, for example to other adjustments, can be effected simultaneously, an adjustment of the second longitudinal fold and / or an adjustment of a perforating knife for longitudinal perforation.

In the above context, the term "path processing tools" is thus to be understood in the broad sense also as meaning sensors and actuator systems which exert an influence on the detection and influencing of the path of a web or partial web or strand.

When the printing machine is preset, for example, the system S receives from a product planning system, a print preparation stage, the printer itself and / or a present imposition system, the system S for the pre-setting relevant data for the planned production. The imposition scheme includes, for example, the railway or subway paths intended for the planned production as well as the occupation of the form cylinders with the printing pages as well as the colors of the individual printing units. Information about the web width and / or the intended lateral position of the web can be entered by the printer or can be obtained from a machine control, the roller changer 71 itself, a logistics system or a product planning system.

For the positioning of the longitudinal cutting device 71 and / or the roller changer 61, the information concerning the planned web width and / or web position, for which the folding former 06; 07 the partial web width. For the positioning of the reversing rods 37; 38 and, if appropriate, of a longitudinal register device 58 assigned to the partial web in the superstructure 67, the information on the intended path or partial path paths, for example, is processed. In a further development, a presetting of color testers in the printing units can be performed, for example, using data from the printing preparation and / or the imposition scheme (color densities, occupancy, etc.).

In an advantageous first variant of a simplest embodiment of the printing machine, at least the system S is used to preset the longitudinal cutting device 71 with regard to the web to be processed. In this case, the roller changer 61 can always be adjusted to the center without an "external" presetting by a separate internal control loop. In a further development, the system S can also be used in this process for the folding funnel 06; 07 or the funnel unit 73 (laterally and / or in the direction of travel of the paper).

In a second variant of the printing press, at least the positioning (laterally and / or in the direction of travel of the paper) of the folding former 06; 07 or the former 06; 07 is preset. A knife 05 and / or a downstream driven roller 30 can then be positioned together with the folding former 06, 07 and connected to it. In this case, the roller changer 61 can in some cases again be adjusted to the center without an "external" presetting by a separate internal control loop.

In a more comfortable embodiment, the presetting of the system S for the positioning of the former 06; 07 and the turning mechanism 72 and, if necessary, additionally for the roller changer 61.

As an alternative to this, the presetting of the system S for the longitudinal cutting device 71 (ie, at least one knife 28, 32) and the turning device 72, as well as, if necessary, additionally for the roller changer 61 is carried out in one embodiment. In a largely automated embodiment, the former 06; 07.

In addition to the three abovementioned stages, it is advantageously possible to pre-adjust the color knives and / or the stripping elements by the system S.

In principle, a different selection of units or sub-assemblies to be preset can also be provided as required and degree of automation. For example, a presetting can only be directed to the setting of the color knives and the longitudinal cutting device 71, whereas, in a different embodiment, all the aggregates or subassemblies, in particular those of the superstructure 67, are provided for the presetting.

In addition to the abovementioned design stages and their variants, a pre-setting of cutting register and / or color register measuring elements 56, eg heads, and / or a web edge control 57 can advantageously be made in the axial direction with regard to the new production, and / or an adjustment Of the pressure roller 35 (or rollers) on the drawing roller 30 in view of an expected strand thickness below the former 06; 07.

The drives 11; 23, 34, 49 of the said processing tools, at least the processing tools provided for the pre-setting, are preferably designed remotely operable or remotely actuated by the system S or the control 10. In contrast to manual actuators or actuators which are to be actuated only locally, the pre-setting in one or more of the above-mentioned embodiments and variants is thereby possible conveniently and quickly via the system S and / or the control station.

The system S can be implemented as a control unit S, which has a user interface for inputting and / or an interface for reading (from the machine control, a production planning system and / or a printing preparation stage) at least one width and / or one path of a web to be processed Determining a desired position of the units to be preset, subassemblies or processing tools such as the roll changer 61, the longitudinal cutting device 71, the turning rod 37; 38, a longitudinal register device 58 assigned to the partial web and / or the former 06; 07 on the basis of the web width and / or the path as well as the driver for activating the assigned actuators in order to set the respectively determined desired position.
