Claims. (Cl. 270—53)

This invention relates generally to the manufacture of multiple-copy or manifold business forms, and in particular to a collating machine for assembling snap-out sets or continuous business forms, and adapted to interleave a tab card with the sheets in the set or form.

Because of the complexity of modern business practices, transactions are usually recorded on multiple-copy forms, the various copies being intended for distribution to different branches of the organization. Such forms are conventionally made by collating together original, duplicate, triplicate and further copy sheets with carbon paper, each such combination producing a complete set.

It is now also common practice to include a so-called tabulating or tab card in each set. A tab card is intended to receive the data impressed on the original sheet of the set, for later use in conjunction with IBM, Remington Rand or other types of punch card systems to process data for accounting or other purposes.

Since all of the sheets in a set are of the same length, they are relatively easy to collate. The tab card, on the other hand, has smaller dimensions. Hence the only feasible way by which it has hitherto been possible to insert a tab card in the set, was at a position in registration with the upper or lower edge of the associated sheets, the corresponding edge of the card being aligned in a guide with the edges of the sheets. Since in some instances it may be necessary to place the tab card at a selected intermediate position with respect to the associated sheets, this creates practical difficulties when using conventional collating techniques.

In the case of continuous business forms which are made by combining webs of paper and carbon which are divided into forms by spaced transverse lines of perforation, it has not heretofore been possible to insert tab cards therein in that no edges exist against which the card can be registered.

Accordingly, it is the main object of this invention to provide a collating machine for assembling snap-out sets or continuous business forms, and adapted automatically to insert tab cards therein at any selected position.

More specifically, it is an object of the invention to provide a machine of the above type which acts to interleave moving webs of roll carbon with webs of roll paper and to dispense tab cards periodically between two of these webs at a predetermined position, whereby the cards are interleaved therewith. Thus the insertion of tab cards is not limited to sets, and may take place with continuous forms as well.

Yet another object of this invention is to provide a machine of the above type which operates efficiently at high speed, thereby effecting significant economies in the cost of producing the snap-out sets or continuous forms.

Briefly stated, these objects are accomplished in a collating machine operating in conjunction with paper and carbon rolls, the several webs travelling toward combining rolls. By means of roller or other guide means, an open shed is formed in advance of the combining rolls between those carbon and paper sheets which are to appear above the tab card and those below the card, and within this shed there is disposed a tab card dispenser acting periodically to lay down tab cards on the lower sheets of the webs. The dispensing operation is so timed with respect to the movement of the sheets as to place the cards at a selected position with respect to the associated forms.

For a better understanding of the invention as well as other objects and further features thereof, reference is made to the following detailed description to be read in conjunction with the accompanying drawings, wherein: 5 FIG. 1 is a plan view of a complete, snap-out set in accordance with the invention, incorporating a tab card, the sheets being cut away to expose underlying sheets;

FIG. 2 is a separate plan view of an individual tab card;

FIG. 3 is a schematic diagram of a collating machine IQ in accordance with the invention;

FIG. 4 is an enlarged schematic diagram showing the card-inserting and crimping section of the collating machine;

FIG. 5 is an elevational view of the crimping wheels; 15 FIG. 6 is an end view of the crimping wheels; and

FIG. 7 is a plan view of continuous business forms in accordance with the invention, incorporating a tab card, the sheets being cut away to expose underlying sheets.

2o Snap-out sets and continuous forms

Referring now to the drawing, and more particularly to FIG. 1, there is shown a sample tabulating-card snapout set constituted by an original sheet 1, a first carbon 25 paper A, a duplicate sheet 2, a second carbon paper B, a tab card TC, a third carbon paper C, and a triplicate sheet 3. All of the sheets as well as the tab cards are provided on the right margin with sprocket holes 4, and parallel thereto is a line of perforations 5. The sheets 30 and papers are all of the same length, but the carbon papers are wider to provide uncoated margins M to facilitate separating the carbons from the sheets. The various sheets and tab card are glued together to prevent their separation until such time as they are snapped off the 35 margin along the line of perforation.

It will be seen that the tab card TC, also shown separately in FIG. 2, has the dimensions of a so-called IBM card, and that it is aligned adjacent the upper edge of the set. Hence entries are made on the tab card cor40 responding only to entries made on the upper portion of original sheet 1, whereas entries made on the remaining portion of the original are reproduced on the duplicate 2 and triplicate 3. The problem to which the present invention is addressed is the insertion of the tab card at a 45 position in registration with the appropriate portion of the associated sheets.

It is to be understood that the tab card, while shown adjacent the upper edge of the sheets, may in accordance with the invention be placed adjacent the lower edge or 50 at any intermediate position between these edges. In practice, the tab card is never brought closer than about one-eighth of an inch to the top or bottom edge of the set, rather than aligned therewith, for otherwise when the sheets are cut by a knife to form a set, the knife might 55 cut into the card and spoil its very accurate dimensions.

In the continuous form shown in FIG. 7, the tab card TC is at an intermediate position between the ends of each set. Instead of individual sets which are made by collating and gluing the various sheets in continuous web θθ form and then sectioning the combined webs into sepparate sets, the sets remain interconnected by transverse lines of perforation P_1; P₂, etc., whereby the sets may be fed uninterruptedly into an accounting machine and separated only after the data is recorded thereon.

⁶⁵ The number of paper sheets and carbons shown in FIGS. 1 and 7, is for purposes of illustration only, and it is to be understood that a machine in accordance with the invention, while shown herein in a form adapted to make γθ a snap-out set of the FIG. 1 or FIG. 7 type, is also capable of making sets or forms with any desired number of paper copies and carbons.

The collating machine system

Referring now to FIG. 3, there is schematically shown a collator in accordance with the invention, the machine being arranged to make snap-out forms of the type shown in FIG. 1, or continuous forms of the type shown in FIG. 7. Thus the machine is provided with a series of unwind rolls carrying the rolls of original paper 1, duplicate paper 2, and triplicate paper 3, as well as carbons A, B and C. All of the papers (not the carbons), as pointed out previously, are marginally punched. The carbon sheets are not ordinarily marginally punched unless there is a pattern of carbonization thereon which must be registered with the printed material on the sheets. In the ordinary case (full carbonizing) only friction carries the carbon webs.

The machine is adapted to interleave the roll carbon with the roll paper, to glue the sheets together, to cut off to size, and to deliver the resultant sets in counted stacks. In the case of continuous forms, in lieu of cut-off rolls, the machine is provided with a perforating device to impress transverse lines of perforations between succeeding forms. Many of the components of the machine are standard in the industry, and hence will not be spelled out in detail. These details are found in such standard commercial machines as the snap-out collators manufactured by Schriber Machinery Company of Dayton, Ohio, and identified as “Six-Part Continuous Gluing Collator” or “Eight-Part Unit Set Collator.” However, such machines have no provisions for inserting tab cards.

Each paper and carbon web, after leaving the unwind roll, goes through a suitable guide over a pin cylinder. Pin cylinders 6 to 11 are provided for the respective webs. These cylinders preferably incorporate disappearing pins to permit the associated web to strip clean from the pins without tearing the holes when leaving the cylinder. The machine is equipped with gluing devices (not shown) to apply a continuous line of glue adjacent the longitudinal line of. perforations for holding the sheets together in set form. ’ At the output end of the machine, after the sheets and tab card are combined, the continuous web goes through cut-off rolls 12 and 12A which section the web into individual snap-out sets and feed them to a discharge table. Instead of a cut-off roll, the webs may be perforated at this point.

The four webs derived from original roll 1, carbon roll A, duplicate roll 2, and carbon roll B, which ride over pin cylinders 6, 7, 8 and 9, respectively, travel in the horizontal plane and come together under a roll 13, from which point they travel upwardly until they reach an elevated roll 14. The four webs ride over roll 14 and again travel in the horizontal plane toward a roll 15 at the same elevation as roll 14, thus raising these webs with respect to the remaining webs. From roll 15 the four webs travel downwardly toward combining rolls 16 and 16A where they join the two lower webs drawn from the carbon roll C and the triplicate roll 3. From the combining rolls the combined webs which, as will be later explained, have the tab cards interleaved therewith, go to the cut-off rolls 12 and 12A for sectioning.

The lower webs from carbon roll C and triplicate roll 3 travel over their respective pin cylinders 10 and 11 and then over a roll 17 which is horizontally in line with combining roll 16A. The gluing devices to apply glue to the various sheets are not shown, for they are entirely conventional and are not pertinent to the salient aspects of the present invention. Such gluing devices may be found in the machines manufactured by Schriber Machinery Company.

The combined carbon web C and triplicate web 3 travel in the horizontal plane toward the combining rolls 16 and 16A and their sprocket holes are engaged by the pins of a continuous sprocket chain 18 supported between sprocket wheels 19 and 20. The space opened up by rolls 14 and 15 between the horizontally moving webs C and and the elevated webs 1, A, 2 and B, constitutes an open shed 21. Within this shed there is supported a tab-card dispenser, generally designated by numeral 22, which periodically supplies tab cards TC to a feed drum 23, the 5 drum in turn laying down the cards one at a time onto the web of carbon C, the pins on the sprocket chain entering the sprocket holes on the tab card. The timing of this dispensing action, as will be shown in greater detail in FIG. 4, is such as to place the card in its desired position ₁₀ of registration.

In the system shown, glue is applied marginally to the surfaces of the webs before they enter the combining rolls. Since the glue applied to the upper surface of carbon C is still wet and the tab card TC lying thereover may fail 15 to remain in its proper place after it leaves the sprocket chain 18, a crimper wheel 24 operating in conjunction with a platen wheel 25 serves to mechanically lock the tab card TC to the webs therebelow to prevent displacement of the tab card. '

Thus the essential features of the invention reside in a collating arrangement wherein the webs of paper and carbon which in the final set, appear above the· tab card, are first combined and then conveyed along a path which is elevated relative to the combined webs of the paper 25 and carbon appearing below the tab card, thereby defining an operating shed for accommodating a card dispenser. The cards are laid down periodically on the combined lower webs moving within the shed, and thereafter the combined upper webs and the combined lower webs enter 30 the combining rolls to form the complete combination containing the tab card.

The card inserter

Referring now to FIG. 4, showing the card inserter 35 arrangement within shed 21, it will be seen that tab cards TC, which are stacked in the dispenser 22, are fed one by one to the card feed drum 23 which in turn lays down the tab cards over the combined webs of carbon C and triplicate 3, at a position in line with the sprocket holes 40 therein. These combined webs travel under the drum 23, the sprocket holes in these webs being engaged by the pins in the sprocket chains 18 running between sprocket wheels 19 and 20.

The main drive gear 26 of the machine engages idler ._ gear 27 which, through an intermediate gear 28 meshing with gear 29 on the shaft of sprocket wheel 19, operates the sprocket chain 18. Gear 28 in this train also meshes with idler gear 30 engaging the gear 31 on the shaft 32 of the anvil wheel, thereby driving the crimper blade go wheel 24 through a set of gears to be later described. The gear ratio of this arrangement is such that anvil wheel 25 is caused to rotate at a faster surface speed than that of the paper web, to ensure that the anvil will pull the paper from the crimper blade and also reduce wear on _5g the anvil in that the blade generally strikes the anvil at a different point thereon with each rotation, and in a practical embodiment only hits the same spot once per 41 revolutions.

Supported on the shaft 33 of the sprocket wheel 20 are 00 two identical gears 34, one of which engages an idler gear 35 intermeshing with a larger gear 36 on a shaft 37, and the other of which (not shown) engages an idler gear 38 intermeshing with a smaller gear 39 on shaft 37. The two gears 34 have set screws thereon so that it is possible 05 to key one of these gears to the shaft while the other remains inactive, thereby selecting the effective gear ratio between shaft 33 on the sprocket wheel and shaft 37. Shaft 37, by means of a suitable gear train (not shown), is operatively coupled to the feed drum 23, whereby the 70 drum is caused to rotate at a rate synchronized with the advance of the paper webs over the sprocket chain 18.

The feed drum 23 is provided with two sets of pivoted grippers 40 and 41 disposed 180° apart. Both sets of grippers operate at all times, but deliver and place cards 75 only when cards are fed from the card stack by a card

3,249,352 feed actuator 42. Card feed actuator 42 is adapted to engage the lowermost card in the stack and to slide this card out of the stack through feed rolls 43 and 43A onto the drum, where the card is then clamped to the periphery of the drum by the operative gripper. The actuator is reciprocated by linkage arms 44. The end of the linkage arms is pivoted at an eccentric on wheel 45, whereby rotation of this wheel causes the actuator to reciprocate. Wheel 45 is operated at a desired speed through a train of gears 46 and 47. Wheel 45 also engages a wheel 48 provided with opposing cam triggers 49 and 50, which as the wheel rotates engage the cams 40A and 41A on the grippers 40 and 41 to open each gripper when the drum carries a card onto the pins of the chain and to close the gripper when a card is fed into the drum.

The crimper assembly temporarily holds the tab cards on the paper while the glue which has been applied dries firmly. In this assembly, as is best seen in FIGS. 5 and 6, the crimper wheel generally designated by numeral 24, includes a pentagon-shaped crimper blade 24A and a notched wheel 24B which is designed to mesh with the pins in the sprocket chain 18, thereby ensuring a line-up of the cards to pins. The crimper blade 24A is received within the anvil wheel 25. The anvil wheel includes a gear 25A which interconnects with gears 24C on the crimper wheel to drive same as the anvil wheel is rotated.

While there has been shown and described a preferred embodiment of my invention, it will be appreciated that many changes and modifications may be made therein without, however, departing from the essential spirit of the invention as defined in the annexed claims. For example, while the shed is formed by raising some webs with respect to the others, the shed may be formed by separating the webs in other planes to provide the necessary space for the tab card insert.
