formed guide organ arranged, which in the manufacture of the initial winding layers with the winding rolls and the winding mandrel cooperates. As shown in FIGS. J and 4, the slide arranged on the left side of the machine is equipped with a lower guide device 40 and the one on the right side of the machine provided carriages with guide devices 42 and 44 arranged one above the other. The guiding devices have pivotable guide members which are advanced against the mandrel 12 with the aid of the slide and moved back from this can be.

The winding machine is further provided with a pair of driven transport rollers 46 and 48, which a metal belt S or the like. to the machine. One or more winding machines can be installed in the transport path of the metal strip to be wound be arranged. Driven transport rollers 50, which are a metal belt, are provided on the top of the machine frame After completion of a winding process on the winding mandrel 12, move it over the machine and convey it. in the Transport path is a pivotable switch 52, which in its 3Fig. 5 pivot position shown the front End of a tapered metal strip down into the machine frame 10 diverts. The front end of the belt in the infeed area is guided by a fixed guide element 56 »a guide organ of the guide device 42 and an upper IHihrungsorgan 54 supports which with the! guide element 56 and the guide element forms a funnel-shaped inlet channel. If the switch 52 is moved down

4 03851/0251

pivots, the front end of the incoming metal strip S is past the winding machine over the roller conveyor 50 transported on.

When a metal strip is to be wound in the winding machine, it is passed over the of the guide elements ^ ¹ V and 56 and the guide member 42 funnel-shaped guide channel formed downwardly in the direction of the circumference of the "mandrels s 12th In this process, there are the Winding rollers, and the guide elements in their operating position near the winding dome 12, so that the front end of the tapering metal strip S is guided counterclockwise around the winding mandrel 12. The winding mandrel 12 is driven counterclockwise, while the winding rollers 32 are driven clockwise circulate, as indicated in Pig. 3 and by the arrows. The winding rollers 32 and the fixed guide elements 3 ^ as well as the guide devices 40, 42 and 44 are placed against the winding mandrel 12, so that the incoming tape is formed around the winding mandrel. whereby the first winding layers are formed on the winding mandrel As soon as the first winding layers g have been wound, the carriages 16 are moved back by the mandrel, whereby the necessary space for the completion of the winding body is created on the circumference of the winding mandrel.

The winding rollers and / or the guide elements arranged with them on the slide are in their spatial position relative to the

409851/0251

Winding mandrel 12 adjustable for precise gap adjustment and / or alignment of these parts with respect to the winding mandrel to enable. In the following, the adjustment device for the winding rolls will first be explained-

As FIGS. 1 and 5 show, the support 30 has the winding roller device 14 a vertical bearing plate 57 and two fork-shaped bearing arms 58 attached to it at the ends on, on which the winding rollers 32 opposite the support JO are rotatably mounted. In the illustrated embodiment, the two bearing arms 58 are at the ends of the four Winding rollers are designed to be identical to one another. As FIGS. To 8 show, each bearing arm 58 has an opening 60 for the inclusion of the relevant end of the winding roll 32 on. The winding roll consists, for example, of a steel shaft 62 and a metal jacket 64, which is connected to the shaft in a rotationally locked manner is. In the circular bearing opening 60, a bearing bush is arranged, which is designed as an eccentric bush 66 is. The bush 66 has a circular inner opening, the central axis 72 of which is eccentric to the central axis 68 the bearing opening 60 or the cylindrical outer circumference of the eccentric bushing is arranged. In the inner opening 70 is a spherical roller bearing assembly 74 around the end of the shaft 62 arranged around, which supports the winding roll 32 rotatably about the axis 72- It can be seen that upon rotation of the eccentric bushing 66 about the axis 68 the angular position of the axis 72 relative to the axis 68 and thus the distance between

409851/0251

see the axis 72 and the axis of the mandrel 12 changed will. In order to be able to rotate the eccentric bushing in the bearing opening, the bushing has an interlocking 76 which the outer end face of the bearing arm 58 engages over. Of the Annular flange 76 is arranged with distributed over its circumference Open-edged recesses 78 provided, cite which projections or fingers 80 lie. In addition, the puddle 76 has a larger number distributed over the circumference Flange openings for receiving screws 82. The bearing arm 58 is correspondingly with a larger number provided on threaded holes 84 in which the screws can be screwed in, which define the eccentric bushing 66 in any desired rotational position on the bearing arm 58. At the Bearing arm 58 is wedge-shaped by means of two screws 88 Alignment member 86 attached, which with a nose 90 engages in the recess 78 on the single flange. With help of the alignment member 86, the screw openings of the flange 76 and the threaded bores 84 of the bearing arm 58 Align each time the eccentric bushing is adjusted.

To adjust the winding roll, loosen the screws 88 first the alignment member 86 is removed, whereupon the screws 82 are loosened. Then the eccentric bush 66 can be rotated in the bearing opening with the aid of a tool, e.g. a bolt wrench or the like. Included adjustment in small steps is possible, the size of which depends on the circumferential distance of the threaded hole

403851/0251

stanchions 84 of the bearing arm 58. After the adjustment of the eccentric bushing, the alignment element 86 is reconnected, which in this case the corresponding openings in the flange 76 and the threaded bores 84 brings into exact congruence, so that the screws 82 can be screwed in again to fix the eccentric bushing in the desired rotational position.

It goes without saying that the amount by which the rotary movement the eccentric can be gradually adjusted, can be variable. For example, the setting levels by the number of bolt openings of the flange 76 arranged over the circumference and by the number of the threaded bores 84 of the bearing arm 58.

In the preferred embodiment, the winding rolls are separately adjustable at both ends in the manner described, so that the winding rollers by adjustment their location at one or both ends of the bearing in an exact axially parallel alignment to the winding mandrel axis or in an inclined position to the winding mandrel axis can be brought. But it would also be possible to make the arrangement so that the winding rollers only on their a bearing end can be adjusted. The other end of the camp the winding roll can then be mounted in a spherical bearing so that it is possible to adjust the winding roll at the other end of the camp.

From Pig. 5 it can be seen that the upper guide device

409851/0251

a pivotably mounted, designed in the manner of a pivot plate Guide member 92 with a piston-cylinder swivel device assigned to it 94 has. The lower guide device 44 is correspondingly provided with a pivotable guide member 96 and a cylinder pivot device 98 is provided. The two guide members 92 and 96 are pivotable on the slide stored so that they grip the winding rolls from the outside. The inner baffles 100 and 102 of the two Guide members 92 and 96 can be, as shown, in Set a narrow gap distance against the circumference of the winding mandrel 12 to get the initial winding layers at the beginning of the winding process manufacture on the mandrel. The employment of the guide elements against the winding mandrel is done with the help of the Piston-cylinder devices.

In the preferred embodiment, the guide members on adjusting devices to their position relative to the To be able to adjust the winding mandrel and / or the neighboring winding rollers. The arrangement is such that the pivot axis of the guide members 92 and 96 relative to the Slide is angle adjustable. In addition, the cylinders of the piston-cylinder devices of the guide elements on the Slide mounted pivotably, the joint axes of the cylinder connection joints also opposite the slide are angle adjustable. In the pig. 5 »8 and 9 a suitable adjustment device for the guide elements is shown.

The guiding devices 40, 42 and 44 are in the same way

409851/0251

stored on the carriage 16, so that in the following only the 'Storage of the guide device 44 in detail' needs to be explained. Like the Pig. 5 and 8 show the Carriage 16 support arms 104 with aligned openings 105 and bearings 107 for the hinge axis 106 of the guide device on. At one or both ends of the hinge axis 106 is a face plate 108, e.g., by welding attached, which is provided with a screw head 110 to den'ein wrench or the like. to rotate the joint axis 106 can be applied. The end plate 108 has a number of bolt openings distributed over the circumference for holding screws 112 on. The bearing arm of the slide is correspondingly provided with threaded holes 114 for the screws 112 are provided. With the help of the screws 112 can thus the hinge axis 106 can be fixed on the bearing arm 104 of the carriage.

The pivot axis 106, which is rotatable about its longitudinal axis 116, has eccentric shaft sections 118 between its ends, of which only a single shaft section can be seen in FIG. 8. The axis 120 of the shaft sections 118 runs eccentric to the axis 116. The guide member 96 has arms which are each rotatably connected to a shaft section 118 about the axis 120. Depending on the length of the guiding organs the number of arms 122 and, accordingly, the number of eccentric shaft sections 118 can be different. In the illustrated exemplary embodiment, each guide

409851/0251

organ two arms 122 which cut on two eccentric shafts 118 of the hinge axis 106 are articulated. The angular position of the joint axis 120 of the guide member opposite the axis 116 of the joint axis 106 can be adjusted in stages by loosening the screws 112 and the Joint axis 106 rotated with the aid of the screw head 110 will. The size of the setting is dependent on the number of bolt holes arranged on the circumference of the plate 108 and / or the threaded bores 114 of the support arm 104. By adjusting the angle of rotation of the axis 120 opposite the axis 116 can be used to change the position of the guide element in relation to the winding mandrel and the adjacent winding roll, when these parts are in the operating position shown in FIG.

As mentioned, the guide members are pivoted with the aid of piston-cylinder devices 94 and 98. The setting the guide members opposite the winding mandrel 12 and the adjacent winding roll is in the preferred embodiment of the invention is additionally made possible by adjusting the Eolben cylinder devices with respect to the carriage 16. The piston-cylinder devices of the individual guide elements can have different dimensions; their joint connection is of the same design. As shown in FIGS. 5 and 9, the piston-cylinder device 98 a cylinder 124 with a piston rod. The cylinder is preferably a double-acting

409851/0251

"Barrel compressed air cylinder. Its piston rod 126 is on the Guide member 96 is articulated so that it is pivoted when the piston rod is pushed in and out.

The carriage 16 has support arms 128 on both sides of the cylinder 124 are arranged and each have a circular receiving opening 130 for receiving a cylindrical Have eccentric bushing 132. Trained as a bearing bush Eccentric bushing 132 is around 128 to support arm the central axis 134 is rotatable. It is circular with a Bearing opening 136 is provided, the axis of which 138 relative to the Axis 134 is offset. The cylinder 124 has two diametrically opposite sides on pins 140 which are mounted in the bearing openings I36 of the eccentric bushes. The journals 140 are arranged in a bearing opening 136 Bearing bush 142 rotatably mounted so that the cylinder 124 on the support arms 128 can be pivoted about the axis 138 is.

In the same way as the winding roller bearings, the eccentric bushing 132 has a circumferential flange 144 which extends against the outer surface of the support arm 128. The tab 144 is provided with bolt holes for screws 146 while the support arm 128 has threaded bores 148 into which the screws 146 can be screwed. After removal of the screws 146, the eccentric bushing 132 can be rotated relative to the axis 134 and thus an angular adjustment of the Cylinder joint axis I38 opposite axis 134 causes

409851/0251

will. After the angle adjustment, the screws reinserted and screwed to the slide support arm 128, whereby the eccentric bushing 132 is in its adjustment position is set on the support arm. From FIG. 5 it can be seen that with this setting the cylinder axis 138 compared to the Vickel mandrel axis and the guide element pivot axis 120 is changed, whereby a position adjustment of the guide member 96 relative to the winding mandrel 12 and the adjacent one Winding roll 32 is brought about. The governing body 96 is actuated by a pair of piston-cylinder devices, each cylinder having a joint associated with it Adjusting device of the type described is provided.

The guidance of the carriages 16 in the machine frame 10 can be seen primarily in FIGS. 4, 5, 11 and 13. the consisting of a steel structure carriages have a substantially rectangular cross-section, wherein their side walls 149 and 151 with one another via cross connectors connected and the side walls 18 and 20 of the machine frame 10 are facing.

In the illustrated embodiment, for the reciprocating movement of the carriage 16 in the Machine frame 10 uses three compressed air cylinders 39,

409851/0251

which by means of a steel tube "150, a console 152 and lateral bearing blocks 154- on the opposite side walls of the machine frame are supported. The pipe 150 connecting the side walls 18 and 20 is with these side walls e.g. connected by welding. The bracket 152 arranged on the pipe has bearing arms 155, each of which Reach into the gaps between two adjacent cylinders and at their upper ends have pivot bearings in which pivot pins 157 are rotatably mounted, which at diametrically opposite sides of the cylinder 39 are arranged. The two outer cylinders have corresponding Hinge pin, which is in bearing blocks 154- the machine frame side walls are pivotably mounted.

The cylinders 39 are preferably designed as compressed air cylinders. Your piston rods 156 are articulated to the carriage 16 by means of a bolt 158, which is connected to the corresponding Connection organs for the joint connection is provided. It is advisable to provide a limit stop device, which limits the approach path of the slide against the winding mandrel and thus the distance between the winding rolls determined by the winding mandrel. In Figs. 10, 11 and 16 is a preferred embodiment of such a stop limiting device is shown. The limit stop devices have an adjustable lifting device 160 on each side of the machine frame 10.

ORiGiNAL INSPECTED

of the locking bolt, mounted on the support 30 so as to be pivotable. A spring-loaded cam 204 arranged on the support 30 cooperates with recesses 206 and 208 on the hinge connection part of the locking bolt. A nut 210 is screwed onto the outer threaded end of the locking bolt 200. With the aid of the nut 210, the support 30 can be tightened firmly against the side wall 149 of the carriage 16. It is therefore possible, by means of the locking bolt device 192, to pull the cooperating wedge-shaped tongue and groove guides of the slide and the support into firm surface contact. In order to remove the Vickel roller device from the slide, the nut 210 is loosened at least to the extent that the locking bolt 200 can be brought into the pivot position indicated by dash-dotted lines (FIG. 14). In this pivot position, the locking bolt is held by the cam 204 which engages in the recess 208. The winding roll device can then be removed from the carriage unhindered. When the winding roll device is connected to the carriage, the wedge-shaped tongue and groove guides come into contact with the surface, as a result of which the support 30 is held in the vicinity of the wall 149 of the carriage by a stop . The locking bolt 200 can now position to the full excellent seal Retired be swiveled, is tightened whereupon the mother 210th When the nut 210 is tightened, the winding roller device and the carriage are firmly clamped together.

It is understood that instead of the releasable locking device fastening devices of other designs could also be used.

Venn the "bias between the winding reel device and the slide is lifted when the winding roll device is removed, the fixed surface area system can between the wedge-shaped tongue and groove guides be so large that a certain force is required to the frictional engagement between cancel the wedge-shaped guide surfaces. This force can be generated by a different type of ventilation device be applied. In the illustrated embodiment, the initial displacement of the winding roll device takes place in the direction of the side wall 20 of the machine frame 10 with the aid of a piston mechanism actuated by pressure medium 212, which, as FIG. 13 shows, on the side wall 149 of the carriage 16 below the locking bolt device 192 is arranged. The piston mechanism 212 is in Pig. shown separately. He has a hydraulic cylinder 214 with a piston 216, which is with his free End against the support 30 of the winding roll device puts. When the cylinder is pressurized with pressure medium, the piston becomes 216 extended from the cylinder 214, whereby he the support 30 from the fully distinguished position to the dashed

409851/0251

dotted position in the direction of the side wall 20 moves. During this movement, the frictional engagement between the wedge-shaped guide surfaces lying on top of one another is established of the support and the slide. The cylinder 214 is pressurized with pressure medium via a connection piece 218. The cylinder 214 is mounted in a bracket 220 on the wall 149 of the carriage, that it can be adjusted with respect to the support 30. the For this purpose, bracket 220 can, for example, be provided with a threaded opening into which the with an external thread provided cylinder 214 is screwed. To fix the cylinder in the respective setting position on the support 30, is a special clamping device or the like. arranged on the console 220.

As mentioned above, each winding roll 32 is of one own, arranged on the side wall 18 of the machine frame Motor driven by a drive shaft. To remove the winding roll devices from the carriage, therefore the couplings between the drive shafts and the winding rollers must be released. For coupling this Parts can be provided devices of different designs. A preferred embodiment of a Drive device and a device assigned to it for holding the drive shafts during removal and Insertion of the winding roll devices is shown in Figs. and 17 shown. The driven end of the winding reels

409851/0251

is provided with a coupling device, which a Coupling part 222 which is drivingly connected at its one end to the associated winding roll is that the coupling with the winding roll device is removable. Pas the other or outer end of the coupling part 222 receives the end of the reel drive shaft 36. The "connection between the coupling part 222 and the drive shaft 36 is designed in the manner of a cardan or ball joint, via which the rotary movement of the shaft 36 occurs the winding roll is transferred. In addition, the connection between the shaft 36 and the coupling 222 allows a relative Longitudinal movement between these parts, which during the adjustment movement of the winding roller device against the Winding mandrel and results in the return of the winding roller device from the winding mandrel. In Fig. 17 are the motions of these parts indicated by dash-dotted lines - The adjustable drive connection can be achieved, for example be that the coupling device and the cooperating end of the drive shaft 36 with a notch teeth are provided.

Since a winding roll is provided with its own drive shaft 36, one must be provided for each winding roll device two superimposed drive shafts 36 for the winding rolls arranged one above the other. The drive shafts 36 are arranged suspended between the driven ends of the winding rollers and the corresponding coupling parts of the drives 38. TIm doing the drive shafts

409851/0251

when the couplings 222 are released, 'and around at the same time restoring the couplings after replacement To facilitate the winding roll devices, a special shaft support device 224 is provided which according to the invention from supports or the like. consists, each are arranged under the four drive shafts 36.

The supports are designed so that they can be raised in a position in which they the associated drive shaft Support 36 from below so that your coupling with the winding roll can be released or produced while the shaft is held in the predetermined coupling position will. With this setting of the supports, those in coupling engagement with the coupling parts 222 can be removed Pull ends of the shafts 36 axially from the coupling parts, whereby the driving connection of the Winding roller devices is lifted and these can be removed from the machine frame 10. That Loosen the connection between the drive shafts 36 and the coupling parts "222 can for example be accomplished thereby be that the drive shafts 36 are shortened so far, that their ends are out of coupling engagement with the coupling parts 222 slide out. This shortening of the waves can be achieved in different ways. For example can an intermediate portion of the shafts 36 with a serration 226 or the like. be provided while the neighboring Part 228 of the shafts 36 forms a sleeve with a

409851/0251

- 52 -

inner "toothing in the outer toothing 226 telescopically adjustable. The meshing parts accordingly form a rotationally locked, but telescopic one sliding coupling of the shaft sections. To releasably close the parts 226 and 228 in a certain position lock and thus prevent their telescopic movement during the winding operation of the machine, a locking device, a pawl, a stop lock or the like. be provided.

When the drive shaft 36 is released from the coupling part 222 is to be, said locking of the two telescopically displaceable parts 226 and 228 is canceled, so that the part 228 move axially relative to the part 226 and thus the end of the drive shaft out of the coupling part 222 can be pulled out. After the clutch is released, the shaft supports 224 hold the drive shafts in the height at which the drive shafts 36 when the winding roll devices are inserted into the carriages can be reconnected to the coupling parts 222. For releasing the couplings between the drive shafts and the Door directions of different designs can be used with winding rollers.

The shaft supports 224 are in the Pig. 18 and 19 shown. The supports arranged below the drive shafts 36 are of the same design. It can be seen that the upper support is mounted on a bracket 228,

409851/0251

which is attached to the gear housing 26 of the winding mandrel. The lower support, on the other hand, is arranged on an Eonsole 230, which is located on the part supporting the winding machine, e.g. the foundation.

The supports, which are identical to one another, each have a crank 232 with an actuating handle 234 for manual override. The crank 232 is provided with a shaft 236 which passes through a gear housing 238. The rotary movement of the crank 232 is converted into a lifting movement of a lifting rod 240 via the transmission. By Turning the crank in one direction or the other can therefore raise or lower the lifting rod. The lifting rod 240 has at its upper end a support plate 24-2 with two rollers 244 rotatably mounted on it. The roles enable a rotary movement of the drive shaft on top 36 opposite the support in the event of such a rotational movement in the manufacture of the coupling is required to the teeth at the ends of the drive shaft and the coupling part 222 to engage. The rollers 244 can be placed on the support plate 24-2 for alignment of the parts so that the roller axes run parallel to the corresponding drive shaft 36.

During the operation of the winding machine, the shaft support devices are 224- lowered so that their rollers do not rest on the drive shafts. TJm the winding roll devices Removing from the sled will be the supports

409851/0251

extended by actuating the cranks 232 so that they support the drive shafts 36 with their rollers. The shaft parts 226 and 228 are then shifted against each other to such an extent that the ends of the drive shafts come out of the couplings 222 can be pulled out at the ends of the winding rolls. The winding roll devices can then easily can be removed from the associated slide. The shaft support devices 224 meanwhile support the Ends of the drive shafts in the corresponding plane, in the later after the connection of the winding roll device the couplings 222 with the shafts are re-established. This results in making and loosening the couplings as well as when changing the winding roll devices a considerable time saving. Instead of the with a hand crank, actuated supports, lifting and supporting devices of other designs can also be used.

The winding roller devices 14 and the carriages 16 are, as mentioned, provided with wedge-shaped guides, which allow the installation and removal of the winding roller devices in a horizontal direction parallel to the winding mandrel axis. As soon as the coupling of the drive shafts with the winding rollers has been released, all that is needed is the locking bolt device to be released to remove the winding reel device from the carriage. Da, like Mg. 5 shows that the guide elements are pivotably mounted on the slide and that the machine is not in the displacement path of the winding roller

Α0985Ί / 0251

Len device has protruding components, is an · unhindered Installation and removal of the winding roll device possible. It goes without saying that when installing and removing the winding roller devices the carriages are withdrawn from the winding mandrel so that the winding roller assemblies cannot come into contact with the winding mandrel. The governing bodies can be drawn from the in! Ig. 5 position shown be pivoted back outwards to prevent them when installing and removing the winding roll devices come into contact with the winding rolls.

The installation and removal of the winding roll device can be accomplished in various ways. Preferably For this purpose, an auxiliary device provided with a counterweight is used, of which in FIGS. 20 and 21 a preferred embodiment is shown. The auxiliary device has a round rod or rail 246, at one end a counterweight 248 and at its the other end carries a connection head 250. The counterweight 248 and the connection head 250 can be provided with openings in the vicinity of their upper ends, into which the rod with their ends. The rod is fixedly connected to the connection head 250, for example by welding. The counterweight 248 is dr-ehfest an_der pole or the like. attached, preferably such that it can be removed from the rod. This way you can have different levels of severity Connect counterweights to the rod. It goes without saying

409851/0251

that the counterweight 248 need not necessarily be attached to the rod end, but also at a distance of the end of the rod.

The connection head 250 is designed so that a Winding roller device for installation and removal as well as for transport can be connected. Mr the connection Devices of different design can be provided. In the illustrated embodiment the connection head 250 has an insertion opening 252, into which a pin 260 can be inserted, which is arranged on the winding roller device. The pin has a the insertion opening 252 corresponding contour; it is arranged on that side of the winding roll device, ! • / oak facing the side wall 20 of the machine frame is. The spigot may be attached, for example by welding, to a bearing arm 58 of the winding reel device, preferably such that the axis of the pin is in the vertical and horizontal gravity axis of the winding roll device lies.

The insertion opening 252 of the connection head is, as shown in the figure, curved in the upper and lower areas, while their margins are straight. The pin has a corresponding contour. Preferably are on the side edges of the insertion opening 252 wearing plates or lining pieces 262 attached to the side of the opening protrude and stand against the flat side surfaces

409851/0251

of the pin. The flats of the tenon and the Insertion opening cause a non-rotatable connection between the winding roll device and the connection head 250. Um to prevent the pin accidentally out of the insertion opening slides out, it can be provided with an opening 264 into which a stop pin 266 or the like. insertable is.

The rod 246 has several axially spaced apart along its length arranged annular grooves or grooves 268. The loops 270 of a cable or rope are placed in two grooves 272 of a suspension device, e.g. a crane. The loops 270 of the rope 272 either only carry the rod 246 or the rod together with the attached Vickel roller device. Depending on the weight load, the loops 270 are in those grooves 268 of the rod 246 is inserted, in which the weight attached to the pull rope is balanced and kept tipping over. The grooves 268 also prevent the loops 270 from sliding on the '246 rod. The spacing of the grooves is selected so that the suspended load is always attached to the pull rope 272 without tilting.

The device suspended from the cable 272 can be adjusted without difficulty into a position in which the pin 260 of the Vickel roller device 14 can be inserted into the insertion opening 252. Terminal head 250 and counterweight 248 are preferably about the axis of rod 246

409851/0251

intersecting vertical plane arranged symmetrically so that the flats of the insertion opening 252 run vertically, when the pole is hanging on the rope. This facilitates the insertion of the pin into the insertion opening 252.

The counterweight 248 is preferably configured such that it is at least partially below the longitudinal axis of the rod 246 so that the center of gravity of the counterweight is below the hub center point formed by the axis of the rod 246 lies. The connection head 250 also protrudes down the rod 246 so that the center of gravity of the winding tube healing device is below the axis of the rod 246. The low center of gravity of the counterweight 248 causes in advantageously a stabilization of the device against an inclination of the device about the axis of the rod 246. This stabilization is for making the coupling between the device and the winding roll device as well advantageous for the work processes involved in installing and removing the winding roll device.

The weight of the counterweight 248 is essentially the same the weight of the winding roll device 14. As soon as the device is connected to the pin 260 of the winding roll device is, the rope loops 270 are introduced into those Hillen 268, in which the hanging on the rope Weight of the auxiliary device and the winding roll device attached to it is balanced. When using an overhead crane or other lifting device

409851/0251.

direction, the winding roll device can be horizontal pull it off the slide as shown in 3Pig. 20 is indicated by dash-dotted lines. During this process, the deep-seated Center of gravity of the counterweight 248 and the winding roller device 14 a certain pendulum effect, which the rotary movement of the device and the connected to it Winding roller device around the axis of the rod 246 largely prevented. The installation and removal of the winding roll device can therefore be carried out quickly and trouble-free. The take-up reel device removed from the carriage can be transported to a maintenance or repair point hanging on the pull rope without tilting.

With the help of the auxiliary device, the winding roll device When installing, align exactly with the slide so that the wedge-shaped guide strips fit into the keyways can be introduced. Since the device is arranged on the outside of the machine frame, it can the winding roll device can be completely inserted from the outside into the operating position on the slide. Afterward the locking bolt is then used with the help of the locking bolt produced between the winding roller device and the carriage, whereupon the rope loops 270 on the Rod 246 can be hung around and the auxiliary device after pulling the socket pin 266 out of the pin 260 from the machine area Will get removed. Then the coupling between the winding rollers and their drive shafts

409851/0251

produced so that the winding machine is ready for operation again.

Instead of the pin connection described for the coupling of the auxiliary device with the winding roll device other coupling devices can also be used. For example, the auxiliary device with an approach or Projection or the like. be provided while the winding roller device with a corresponding recess or opening for this approach or the like. is provided »The cone and the pin opening can have a different contour, however, the contour of these parts is preferably designed so that a rotationally locking connection is achieved.
