The present invention relates to a method of producing a coil of an elongated flexible article comprising cable, rope, wire, wire, rope, train, belt, hose, chain and the like, and to pack the coil to form a package for delivery to a user. of the article, which article is flushed on an axially open cylindrical sleeve to form said coil. The invention also relates to a new system for handling an elongated flexible article comprising cable, rope, wire, wire, rope, train, band, hose, chain and the like, which is initiated by the manufacture of a coil and packaging of the coil for formation. of a package for delivery to a user, the object being flushed on an axially open cylindrical sleeve to form said coil. In addition, the invention relates to tools for use in this manner and in this system, as well as packages produced by the method.

The system that has so far been widely used for handling e.g. live cable and cable, such as blank line for electric overhead lines, exhibit a number of disadvantages. In the known system, drums made of a wood material are usually boards, and have a core and two gables which are firmly anchored to each other and the core by means of nail and / or bolt joints. The gables are provided with small center holes, the hollow edges of which are usually formed from the wooden material of the gables. The ends determine the outer dimensions of the cable and linen drums and thus the space required for the storage of empty cable and linen drums, which means that large transport and storage spaces are needed to transport and store them before flushing takes place. A drum of the type specified is placed in a coil machine to reel a cable or cable on the core so that a coil of cable or

468 129 rope is formed with a diameter slightly smaller than the end of the gables. Thereafter, the cable or cable drum is transferred from the bobbin to a nearby station, where it is packaged to protect the bobbin from, inter alia, bumps by boards being nailed between the ends while enclosing the coil or enclosing the coil by a cover of corrugated cardboard material. The packaged cable and linen drums are then stored in an adjacent warehouse for later delivery or transported directly to the user. The cable or cable installation must be prepared so that the cable or cable drums are placed at the desired places long before the installation itself, usually about 2 months. During this time, the drums are exposed to moisture and rain and also to direct contact with water on the ground so that there is a favorable environment for rot attacks. In the subsequent cable or cable installation, at the beginning of a mounting section, a drum is placed in a particular reel, while at the end of the installation section an empty drum is placed in a reel, on which the empty drum or cable or a particular draw-line is wound.

In the flushing machine and in the flushing and flushing brackets, bearing members are brought into engagement with the holes in the gables, which holes are consequently subjected to large stresses so that wood material is released, which increases substantially if the gables have root attacks around the hole edges. The center of the hole will be offset from the optimum axis of rotation, causing the drum and coil to be off-centered so that imbalance occurs during rotation of the drum. In the rewinding machine, it becomes problematic to rewind the cable or cable in tight even turns, which can cause damage to the cable or cable so that the entire coil must be discarded as well as the drum. The problem can be reduced by lowering the speed of rotation, but this obviously results in undesirable capacity loss. Because of the very volatile treatment to which the drums are subjected, especially during loading and

468 129 unloading, the gables can be displaced laterally from each other so that the drum becomes skewed. This skewness can be difficult to detect before the flushing begins in the flushing machine and results in the same problem as mentioned above with respect to the difficulty of forming tight even turns of the flushing. In order to reduce the risk of damage to the hole edges of the gable center holes, bushings have been used in some cases which are inserted into correspondingly larger holes in the gables. However, such bushings are also subjected to stress so that they eventually become loose and fall out, which results in excessive holes for the bearing members used in the flushing machine and in the flushing and flushing bins. Even in healthy gables, the center holes may not be properly centered due to the difficulty in manufacturing the gables to place the center holes concentrically with the core around which the cable or cable is to be wound. In addition, imbalance can occur in the drum due to the fact that the pieces of wood have loosened from outer portions of the gables as a result of the excessive treatment that the drum is subjected to during transport between the factory and the workplace, whereby the rot attacks which may be present on the drums, as mentioned above, increase the risk essential for removing pieces of wood from the gables. The said centering and / or the mentioned imbalance also causes large stresses on the unwinding jaws, especially as the winding mostly occurs at relatively high speed, which can also vary so that heavy jerking occurs in the cable or cable with consequent stresses on the winding jaw and the storage means thereof. . As the stresses become too great, there is a risk of the drum falling down from the rewind bins, resulting in an unacceptable downtime. The drum can then be damaged, many times so seriously that it cannot be placed on the rewinding trays, but the rest of the cable or cable must be discarded as well as the drum. During the rewind, twisting can occur in the cable or cable so that it hits the ends, and if the ends then

468 129 are damaged in their edges, there is also a risk of damage to the cable or cable, which is completely unacceptable with very unfavorable consequences, especially if the damage is not detected until the high voltage line or other power line is to be taken or put into service.

When transporting the cable or cable drums, these must be placed upright, i.e. the center shaft should be horizontally aligned, thereby ensuring that the turns of the cable or cable are maintained close to each other in each layer, which is not possible if the drums are positioned so that the center shaft becomes vertical. The drums take up significantly more space in the upright position than in the upright position and thus cannot be stored on top of each other. When loading, a forklift must be used which, with its forks, intervenes under the gables, whose edge portions as well as the cable or cable can easily be damaged during lifting, especially if the edge portions have a rotten grip. During unloading, rods are applied through the center holes of the gables to form brackets for a lifting device. This unloading work is therefore relatively time-consuming. Drums that have been placed in the ground must then be lifted up and placed on the reel blocks, which can be done with tools that can cause serious damage to the ends. In some cases, the coil can also be deliberately interrupted to damage the cable or cable.

The flushed empty wooden drums should normally return to the factory for reuse. This return can be delayed for a long time, which means that the wooden drums are subjected to further detrimental effects on moisture and water with consequent rot on the gables so that the pieces of wood come loose and fall away from the gables during the continued handling of the wooden drums. The discarding of the empty drums for return is therefore also very high.

The drums are designed in such a way that the user cannot repair the damage mentioned himself to enable repurchase

468 129 and reuse. On the other hand, as mentioned above, the empty drums have such bulky shape that the storage and transport costs become unacceptably high so that the return provides poor profitability or no profit at all for the user in relation to the cost of purchasing a new drum from the factory (which of course may be a returned drum). The cost to the user with regard to the reuse of the empty drums will also be unacceptably high, in the event that an independent company buys them and then, after a possible repair of damaged drums, sell the drums to the respective factory that supplies drums with cable or cable.

A cable or rope drum, after repeated use, achieves a deterioration in strength and therefore there is a risk that it will eventually not withstand further undue treatment or the normal stresses in the workplace, but the bond between at least one end and the core breaks. The coil of cable or cable becomes unusable and especially if the workplace is located far from the normal transport route, e.g. 20 miles is not uncommon in inaccessible areas such as e.g. in the mountain world, the wrecked drum is left in the workplace. This entails, among other things, increased material costs, since the discarded coil of cable or cable can have a value of thousands of USD, such as e.g. about $ 5,000. In addition, such a failure would result in a very serious downtime, as work must be interrupted and cannot continue until a new cable or cable drum has been transported out to the more or less distant workplace from, at worst, the factory that supplies cable or cable drums of the current type. Due to the large dimensions of the drums, which are determined by the gables, as much of the space between the gables as possible can be utilized for the cable or cable to reduce storage and transport costs. For this reason, a large assortment must

468

<img file="SE468129B_D0003.tif" />

of drums with different diameters on both ends and cores are stored and used to deliver different types of cables and ropes of different lengths and dimensions.

A further problem with the wooden drums is that they are impregnated with agents that are harmful to the environment, so that damaged or used wooden drums must not be burned in the wild but must be disposed of at special depots for environmentally hazardous waste. In addition, incoming metal parts can be treated with environmentally harmful substances, which also prevent the drums from being burned in nature. It will be appreciated that drums left in the ground without being returned constitute sources of emissions into the wild by the aforementioned harmful agents except that animals and humans may be damaged by nails and metal parts exposed during the dredging of the drums.

The recycling of the metal in a scrap rope, which has thus been replaced by a new rope and washed up on an empty wooden drum, is relatively expensive in that the rope must be removed from the wooden drum, since the wooden drum cannot be burned together with the rope partly because of its size. , partly because of its content of foreign metals and chemicals.

From the above it can be seen that the current system for cable and cable management for electricity distribution is associated with problems in virtually all stages of management, which in turn leads to very high extra costs for the installation of cable and cable. There is therefore a great need to create a completely new uniform system for handling e.g. cable and cable and the like from rewinding in the factory to at least rewinding in the field. Solving problems in one of the joints only gives a marginal effect or can create new problems or reinforce the problems in the other joints.

468 129

The object of the present invention is to provide a new way of producing and packaging a coil of an elongated flexible article of the kind specified, such as e.g. cable, cable and the like for electricity distribution and telecommunications, and a new system for handling the cable, cable and the like, which way and which system both eliminates the conventional wooden drums and thus the noticeably many disadvantages and problems that the use of wooden drums entails and partly results in valuable benefits and positive effects at all stages of the handling from the manufacture of the bobbin to the recycling of a so-called scrap line where applicable.

Figures 3-6 illustrate schematically the preparation of a coil 1 of a continuously light flexible article 2 in a stationary coil machine 3 arranged in a factory. For the sake of simplicity and as a preferred embodiment of the invention, the object is hereinafter described as a cable or cable. However, the invention is applicable to other types of similarly flexible articles, i.e. articles which can be wound or wound around a cylindrical core, such as wire, wire, rope, train, belt, hose, chain and the like. The rewinding machine has two about a horizontal axis pivotable support arms 4, 5, which carry bearing means in the form of two axially aligned spindles 6, 7. The support arms can be moved relative to each other for corresponding movement of the spindles 6, 7 from a free starting position according to Figure 3

468 129 to an engagement position according to Figure 4a, in which the spindles 6, 7 have been moved axially to each other. One spindle is driven by a motor 8 in a particular direction. The flushing machine 3 comprises a simple mountable and removable first tool 9, for repeated use in the factory, which tool, as shown in Fig. 1, consists of two circular wheel-like shape-stable side supports 10, 11 of metal, such as steel or aluminum, and an elongated connecting member 12 of metal for fixing the side supports 10, 11 in relation to each other. The connector 12 has an axially through center hole 37 (Fig. 2b) and consists of a hollow shaft 13 of predetermined length and a hollow locking device 14 with an external thread 15 and with a knob 16 for facilitating the rotation of the locking device 14, the shaft 13 at its one end is provided with a counter-forming flange 17 and at its other end with an internal thread 18 adapted to be screwed in with the thread 15 of the locking device 14. Alternatively, the flange 17 can be replaced by a locking device similar to the locking means 14 and an internal threading also at this other end of the shaft 13. In both cases, the connecting means 12 and the side supports 10, 11 are provided with cooperating engaging or carrying means (not shown). fixed to each other for joint rotation. Each side support 10, 11 comprises an externally stable circular ring 19 of a tube, a hub 20 and a plurality of spokes 21 which support and center the hub 20 and define between them functional openings 89. The hub 20 has a center hole 22 (dashed in Figure 2b). ), the diameter of which is adapted to the diameter of the shaft 13 so that it can be slidably passed through the center hole 22 without causing any damage to the stability or centering between the sliding surfaces. Each side support 10, 11 has an interior with spokes 21 formed and spaced apart from hub 20, which are located in a common plane parallel to the plane of corresponding support surfaces 23 of the second side support 11 or 10. Each side supports 10, 11 are

468 129 is further provided on its inside with a centering element 24 concentric with the hub, which has a predetermined axial length and a predetermined radius. In the illustrated embodiment, the centering member 24 consists of three evenly spaced circular arcuate portions to form functional openings 25. The said support surfaces 23 of the spokes 21 are located radially outside the centering elements 24. The centering member 24 is conveniently provided or formed with a plurality of guide lugs 26, the outside of which is inclined inwardly and located in a conical surface generated by the outside.

To prepare a cable or cable package 27 according to the present invention, a core 28 and two lockably connected circular annular flat protective discs 29, 30 are used to form the end walls of the finished cable or cable package 27. The core 28 thus constitutes the inner body or supporting part of the package or coil. The core 28 is in the form of a non-deformable cylindrical axially open sleeve of predetermined length and diameter. The wall of the sleeve is so thick that sufficient strength is obtained so that it is not deformed by the stresses to which the cable or cable package can be subjected. The mold-stable sleeve 28 is weather resistant so that it does not absorb moisture or water even during prolonged contact with water, preferably for at least 3 months. Its inner diameter is equal to or only slightly smaller or larger than the diameter of the centering element 24 so that the end openings of the sleeve can slidably receive the centering element 24 without gap between the cooperating sliding surfaces, thereby ensuring precise centering of the sleeve 28 in the tool 9. The predetermined axial length of the the centering member 24 is selected so as to provide sufficient radial support for the sleeve 28 in the engagement position. The end surfaces 31, 32 of the sleeve 28 are parallel to each other to ensure that the side supports 10, 11 in the mounted operating position of the flushing machine 3 become parallel to each other, whereby

<img file="SE468129B_D0005.tif" />

468

<img file="SE468129B_D0006.tif" />

thus, the end surfaces 31, 32 fully press against the support surfaces 23 formed by the spokes 21. The said flat, i.e. disc-shaped, protective rings 29, 30 have a circular center hole 33 having a diameter slightly larger (see also Figure 27) than the outside diameter of the sleeve 28. so that each protective ring 29, 30 can easily be placed on the sleeve 22 to enclose it at its respective end portion. The protective rings 29, 30 have flat exteriors 34 (Fig. 1) which are located at the flushing moment in the same plane as the end surfaces 31, 32, which plane is thus the same plane as that in which the support surfaces 23 formed by the spokes 21 are located. The outer diameter of the protective rings 29, 30 is slightly smaller than the diameter of the side supports 10, 11. Near the outer edge of each protective ring 29, 30 there are a plurality, e.g. three smaller circumferentially spaced smaller holes 35 (see Figure 2b), the function of which is shown below.

The mounting of the three parts described heretofore to be included in the finished cable or cable package 27, i.e. the sleeve 28 and the two protective rings 29, 30, on the tool 9 is effected by the hollow shaft 13 passing through one of the side supports 10. , 11, is displaced through the axially open sleeve 28 to which the protective rings 29, 30 have been previously applied. Simultaneously or in a previous step, the second side support IX is moved to the other end 32 of the sleeve 28 and the shaft 13 is inserted into the center hole 22 of the hub 20, after which the locking means 14 is threaded with the shaft 13 and rotated around with the centering elements 24 being retracted into the sleeve 28 so that it is clamped between the side supports 10, 11 as shown in Figure 2a. The mounting of the sleeve 28 on the centering elements 24 is facilitated by the guide lugs 26. The sleeve 28 is releasably engaged with the centering elements 24, i.e., it is not necessary to provide a firm connection with mechanical or chemical fasteners. The rotatable first unit 36 ​​thus obtained, which has a rotational axis determined by the center hole 37 of the connecting member 12, is then rolled up to

468 129 the flushing machine 3, whose spindles 6, 7 are engaged with the center hole 37 of the shaft 13 and the locking means 14, after which the unit 36 ​​is raised to the flush position as shown in Fig. 4a. The end of the cable or cable 2 is secured via a hole or recess 38 (see Figure 27) in one of the protective rings 29, 30 so that the cable or cable is fixed in relation to the unit 36 ​​during its rotation about its center or rotation axis coaxial with the axis of rotation of the spindles 6, 7, the unit 36 ​​being rotated in the direction indicated in Figure 4b (the steering wheel 16 has been omitted in said figure). The protective rings 29, 30 are fixed to the lateral supports 10, 11 with suitable fixing means 39 (see Figure 27) so that they rotate together with the lateral supports 10, 11. Prior to the fixation, the protective rings 29, 30 are rotated so that their peripheral holes 35 are axially aligned with each other and so that the holes 35 are within the circular sectors where said openings 25 of the centering element 24 are located (see, for example, Figure 4b). The cable or cable 2 is wound on the sleeve 28 during its rotation so that a coil 1 of a predetermined diameter is obtained which is slightly smaller than the diameter of the protective rings 29, as shown in Figure 5. The unit 36 ​​with cable or lens coil 1 is submerged with the support arms 4, 5, and their spindles 6, 7 are pulled out, after which the unit with cable or lens coil is rolled to a nearby final packaging station according to figures 7 and 8, where first an axially slotted outer protective housing 40 of plastic or cardboard is caused to enclose the entire envelope surface of the coil 1 as illustrated in Figures 7a and 7b. In the next step, bonding means in the form of strap 41 are threaded through the side supports 10, 11, the sleeve 28 and then through the holes 35 in the protective rings 29, 30, after which the straps 41 are stretched and their ends joined together to form a permanent ie strong bond. Each belt thus extends axially with the sleeve and across the turns of cable or cable in an endless loop. The strips, which usually consist of metal or reinforced plastic, enclose the sleeve 28, the protective rings 29, 30, the coil 1 and the protective cover 40 to form a

468

<img file="SE468129B_D0007.tif" />

<img file="SE468129B_D0008.tif" />

finished cable or cable package 27, in which the cable or cable 2 is well protected and clamped so that the turns of the cable or cable are fixed close to each other so that they become completely immobile relative to each other. Spacers may be placed between the protective rings 29, 30 to support the straps 41 so that they do not damage the cable or cable, especially if the protective housing is thin and the cable or cable is of a sensitive type.

Alternatively, the tool 9 may be permanently mounted on the support arms 4, 5 so that its side supports 10, 11 are moved relative to one another by the support arms, while the sleeve 28 is aligned axially between the side supports 10, 11 to engage them as previously described. Thus, in this case, the connecting means 12 can be eliminated and the center hole 22 of the groove 20 can be used for the bearing means, e.g. spindles 6, 7.

Fig. 27 shows a suitable embodiment of a protective ring 29, 30, which on one side is provided with said fixing means 39 in the form of six short pins, which are intended to be placed in pairs on each side of a spigot 21 of a side support 10. 11, the distance between two pins 39 in each pair being sufficiently large that an acre 21 can be freely received therebetween. In addition to the circumferentially positioned holes 35 for gerrying of the straps 41, there is also shown a hole-forming recess 38 at the edge of the center hole 33 for insertion and fixing of the cable or cable end when the flushing is to be initiated. In the above-described embodiment of the protective rings 29, 30, the center hole 33 forms an inner concentric support surface 42 which cooperates with the opposite outer surface of the sleeve 28.

Fig. 28 shows the inverse relationship with internally detachable engagement of the protective ring 29, 30, which on one side is provided with an axially formed concentric flange 43 which encloses the center hole 33 and which has an outer concentric cylindrical support surface 44 which is intended to

468 129 is detachably engaged with the opposing internal surface of the sleeve 28. The flange 43 is preferably provided with a beveled or tapered guide surface 45. Furthermore, the protective ring of Figure 28 is provided with recesses 35 in its peripheral edge portion for receiving the straps 41.

The tool 9 with the finished cable or cable package 27 is rolled up on a ramp 46 so that the side supports 10, 11 are free of the floor as shown in figures 9a and 9b, and the tool 9 can be removed and removed from the finished cable or cable package 27 as shown in Figures 10a and 10b. The cable or cable package 27 is further rolled onto the ramp 46 up to a cradle 47 for placing the cable or cable package T1 in a side loading position as illustrated in Figures 11a, 11b and 11c. With the aid of an expander gripper 48, the cable or cable package 27 is then transferred to a pallet 49, the expander gripper 48 being lowered into the inner cylindrical space of the sleeve 28 and engaged with the inside of the sleeve as illustrated in Figures 12a and 12b. On each pallet 49, several, e.g. two such finished cable or cable packages 27 are placed as illustrated in Figure 12b. The pallets 49 with cable or linen packages 27 are loaded onto a transport vehicle 50 by means of a forklift 51, as illustrated in Figures 13a and 13b, for transport to a field workplace. According to the present invention, by package is meant a package that is ready for direct transport to the user possibly after storage.

At the workplace, cable or cable packages 27 are relieved by the same or another similar expander gripper 48 as illustrated in Figure 14a. The cable or cable package TI can, in connection with the relief, be lowered to parts of a simple mountable and removable other tool 52 (see Figure 14b) for repeated use in the field, which was used as the necessary aid for unwinding the cable or cable 2. The tool 52 similar to what was used in it

468 129 of the flushing machine with respect to the number, type and main embodiment of the main components and thus comprises two uniform side supports 53, 54 of metal, such as steel or aluminum, and an elongated metal connecting member 55 having an axially through center hole 59 (Figure 15d). and consists of a flanged hollow shaft 56 and a hollow locking device 57 for fixing the side supports 53, 54 in relation to each other. The shaft 56 is passed through the center holes of one of the side supports 53, 54 and is held vertically aligned by the side support 53 resting on the ground. Upon immersion, the holes of the cable or cable package 27 receive the shaft 56, which is also received in a central space in the expander gripper 48 so that the cable or cable package 27 can be lowered down to the side support 53. Expander gripper 48 is released and removed, after which the second side support 54 is placed on top of cable or cable package 27 (see Figure 15a) and locking device 57 is threaded with shaft 56 and rotated so that cable or cable package 27 is clamped between the side supports

53, 54 at the same time as their centering element 58, which in this case may be entire rings, centers the sleeve 28 to the side supports 53, 54 so that their center axes coincide with the center axis of the sleeve and cable or cable package 27. The rotatable second unit 60 so obtained is then lifted to the upright position by a hooked wire 84 (see Figures 15b, 15c and 15d) and provided with an elongated bearing shaft 61 inserted through the center hole 59 of the connecting member 55. The ends of the bearing shaft 61 are placed and fixed in a flushing box 62 so that the tool 52 and cable 30 or the cable package 27 are freely rotatably mounted on the bearing shaft 61 (see Figure 16a). Thereafter, the strips 41 are cut and removed and the protective casing 40 is removed as illustrated in Figure 16b, after which the free end of the cable or cable can be connected to one end of a drawbar 69 (see Figure 17), the other end of which is located at another remote work site. for winding the tow line. When the cable or cable is unwound (Figure 18), remove

the cable or line blank second unit 60 from the rewind box 62 (Fig. 19a) and the tool are removed (Fig. 19b) for reuse, while the sleeve 28 and the protective rings 29, 30 are disposable packaging as well as the protective cover 40 and are burned in place or collected.

At said second workplace, a simple mountable and removable third tool 63 (see Figure 20) is used which is similar to that used for the stationary flushing machine 3 and the first workplace for flushing with respect to the number, type and main embodiment of the main components and comprises thus two uniform side supports 64, 65 of metal, such as steel or aluminum, and an elongated metal connecting member 66 which has an axially through center hole 85 (Figure 21b) and consists of a flanged hollow shaft 67 and a hollow locking means 68 for fixing the side supports relative to each other. This third tool 63, which is used in the field in a repeated manner, is mounted in the same manner as the previously described tools 9, 52 during centering and clamping of a sleeve 28a (see Figures 21a and 21b), on which the drawbar 69 is to be wound. The rotatable third unit 70 thus obtained is provided with an elongated bearing shaft 71 which is passed through the center hole 67 of the connecting member 66. The ends of the bearing shaft 71 are placed and stored in a reel flange 72 (see Figure 22) with drive motor 73 and transmission means for rotation of the tool 63 and the sleeve 28a. via the bearing shaft 71, with the appropriate carriers 88 engaging the tool at holes 74 to effect joint rotation. The reel flange 72 is conveniently fixedly mounted on a transport trolley 82 with fold-down restraints 83. Since some protective rings 29, 30 need not be combined with the sleeve 28a in this case, the side supports 64, 65 are provided with walls 75 of e.g. plate, which provides direct support for the draw line 69. Radial openings 76 are formed in the walls 75 in line with axial openings 77 (Figure 20) in the centering elements 78, which openings 76,

468 129 makes it possible to enclose the finished coil 79 with tape 80 in the same manner as in the manufacture of cable or cable package 27. The sleeve 28a may advantageously consist of an empty sleeve 28 obtained in a prior rewinding 5 and consisting of a material which can be incinerated when the coil of traction line 69, which in this case is a scrap line, is melted in a smelter of the linen manufacturer. The coil 79 is thus transported to the smelter as an unpackaged package 81, in which the turns of rope are fixed through the wrapping strips 80.

Alternatively, the second and third tools 52, 63 may also be permanently mounted in a bearing device which can be supported by a vehicle or transport trolley and has support arms which permit parallel movement of the side supports 15 for clamping and releasing a sleeve 28, respectively; 28a with or without coil. In these cases, the connecting members 55, 66 can thus be eliminated.

In the illustrated embodiments, the tools with sleeves are arranged to be stored for rotation about a horizontal axis of rotation. By the invention it is now possible to arrange the tools with sleeves so that they rotate about a vertical axis of rotation as illustrated in Figure 26. This provides advantages especially in the rewind, since the rewind blocks can be eliminated and each rewind position can be more easily selected in that the expanding gripper 48, which in this case is rotatable about its vertical axis, can be engaged with one of the side supports 53, 54 by means of lower hooks 86 , after which the tool 52 with cable or cable package 27 is lifted by means of the gripper 48 so that the tool with cable or cable package can be freely rotatable about the vertical center axis of the gripper. The gripper can be supported by a suitable vehicle 87 which simultaneously transports the tool with cable or cable packages to the correct output position in a power line street for unwinding the cable or cable.

In addition to the protective rings 29, 30 forming a stable packaging for both ends of the cable or linen package to protect the coil 1 during the handling of the package 27, they also serve as auxiliary support for the side supports 10, 11, 53, 54 so that they can be designed with large material saving and weight loss openings such as in the form of the preferred open spokes wheels shown. Thanks to such open spokes wheels 10, 11, 53, 54, the mounted second unit 60 consisting of cable or linen package 27 and the second tool 52 can easily be connected to a lifting device with e.g. a hooked wire 84 as shown in Figure 15b without subjecting this unit to any harmful stresses.

The sleeve 28 may be whole as shown or consist of e.g. two cylinder halves, which at the time of use can be fixed to each other only by means of the enclosing guard rings 29, 30 or by means of suitable binders or fasteners if desired. The split sleeve takes up less space before being used in the flushing machine 3 in that the halves can be stacked together to gain valuable transport and storage space. The sleeve 28 may consist of cardboard, wood fibers, such as chips and chips, or plastic. Since the sleeve consists of cardboard, it is preferably parallel-wound. When the sleeve is made of wood fibers, it is preferably molded by a mixture of wood fibers and a suitable non-harmful adhesive. The protective rings 29, 30 may be made of wood fibers, such as the sleeve, and may be formed by compression molding, such as the sleeve, or may consist of plastic or wood fiber boards, e.g. plywood. The sleeves and protective rings are weather resistant so that they withstand moisture and water under extremely extreme conditions in the outdoors and for a period of preferably at least 3 months. For this purpose, they can be treated during their preparation or after preparation with suitable protective agents, e.g. paraffin which gives the treated material the desired water repellent properties.

Each cable or cable package 27 is prepared using fresh packaging, including sleeve, protective rings and protective casing, which furthermore constitutes dead material, which ensures that the flushing can be carried out with the desired accuracy, since the dimensions of the packaging are maintained; that the coil is not subjected to any stresses, and that any movements within the coil do not occur prior to the coil due to swelling and shrinkage in adjacent materials, as is the case with known wood drums. During storage and transport, the cable or cable package is free from a connector extending through the center of the cable or cable package. The bonding means, i.e., the straps 41, abut against the inside of the sleeve or are located near the inside, i.e. at a distance from the center. In this way, the inner space of the sleeve becomes useful for receiving a gripper for safe lifting of the cable or cable package and even for supporting the cable or cable package for rotation about a vertical axis of the gripper, allowing for a completely new simplified rewinding technique.

The length of the sleeve is adjusted to the amount of cable or cable required in the cable or cable package. In this way, it is possible to use only a few different sizes of the protective rings to cover the need for different lengths of cable and cable ordered by the user.

Thus, the tools described are intended for repeated use at their respective locations and are made of metal to achieve long service life, as well as the desired stability of the three rotatable units. Other material, ie the packaging, in the packages is thus disposable material in the handling chain. The tools as such can also be referred to as bearing means for joint storage of the sleeve with or without coil at bearing means of the stationary coil machine and the field movable and removable
