Description

Method and device for the simultaneous winding of a multi-wire coil with several wires and / or simultaneous unwinding of the wires from such a multi-wire coil for subsequent stranding thereof

The invention relates to a method and a device for winding and / or unwinding multi-wire coils, wherein several wires, in particular wires with a low plastic deformability, such as steel wires, are simultaneously wound onto a multi-wire coil and / or wires wound in such a manner simultaneously processed in stranding devices and then stranded.

In practice, such processes are used for the production of wire strands, which are subdivided into three stages, namely drawing, transporting and stranding, with the associated winding and unwinding processes. From DE 21 39 244 AI it is known to assign a pulling device with a supply spool to several wire drawing machines, the number of wire drawing machines corresponding to the number of wires of the strand or rope to be produced. The individual wires produced are simultaneously wound onto a common supply spool. Subsequently, the wires are drawn off, again simultaneously, from such stationary supply spools and fed to a stranding machine. From DE 39 22 974 AI it is known to draw several wires at the same time with a wire drawing machine and to feed them as a total quantity or divided into partial quantities to one or more winding devices, on each of which a plurality of wires as a bundle together or as an individual - wires are wound up. The process is intended to increase productivity in the wire manufacturing and processing industry. In the case of wires, in particular wires with low plastic deformability, such as steel wires, each wire of the wire bundle is influenced by various winding parameters during the winding process. The interference occurs for example, due to the different surface structure in the run-up area of the individual wires on the winding spool. As a result, different lengths and voltage states are generated per unit of time and wire. If multi-wire winding spools wound in this way are used as winding spools in stranding machines, compliance is the same

Lengths of the individual wires and thus a quality-related stranding of the wires to strands is not guaranteed. Steel wire bundles wound in this way do not meet the requirements for further high-quality stranding on highly productive double-strand stranding machines, as are known from EP 0 563 586.

The invention is based on the object of a method and a device for winding and / or unwinding multi-wire coils, wherein several wires, in particular wires with a low plastic deformability, such as steel wires, are simultaneously wound onto a multi-wire coil and / or such coiled wires at the same time, they are wound up in stranding devices and then stranded, in which the wires can be twisted together in a double lay on high-productive stranding machines according to the principle of multi-wire stranding on the basis of the principle of multi-wire stranding in accordance with the quality, that is to say with the same length relationships in the wire layers.

According to the invention, the object is achieved in that, during the winding process, individual wires run from stationary processes in a winding device and are each fed to their own dancer storage device, and several of these wires are wound onto a common multi-wire coil as a bundle of wires arranged approximately parallel to one another and that while the bundle of wires is being unwound from a multi-wire coil wound in this way, the unwinding device of a stranding device designed as a bobbin supports it , the individual wires are each fed to a stranding process via their own dancer storage device.

In a development of the invention, the individual wires run from the stationary processes and are drawn to the desired wire diameter by means of a wire drawing device, in the form of a multi-wire drawing machine and / or several individual wire drawing machines, and then fed to the own dancer storage device.

To achieve the same wire lengths on the multi-wire spool, it is provided that the individual wires that run from the stationary processes are combined into a bundle of wires immediately before reaching the dancer storage device and that this bundle is subjected to an overturning process, the bundle subsequently being pulled off Dancer device and optionally guided by suitable guide means and then the bundle is unfolded and all wires each run through their own dancer storage device and further via a laying, as a bundle of wires arranged approximately parallel to one another, fed to a regulated multi-wire winder and wound up there on the multi-wire coil.

It is also possible for the individual wires which run from the stationary processes to be guided directly in front of the dancer storage device via their own, separately driven and regulated drawing disk and then fed to a common take-off disk with pressure roller via the respective dancer storage device are, the wires, lying approximately parallel to each other, loop around the take-off disk in one or more turns and then fed as a bundle of wires arranged approximately parallel to one another to the regulated multi-wire winder and wound there on the multi-wire coil. A further embodiment according to the invention consists in that the multi-wire coil wound with the bundle of wires arranged approximately parallel next to one another is stored in the unwinding device of the stranding device designed as a bobbin, the bundling of wires with constant being during the stranding Voltage is drawn off and unfolded, and each wire is guided over its own dancer storage device and finally all the wires to be stranded are twisted in a single stranding point in a double lay to the stranded wire, and after passing through two flyers rotating synchronously to one another be supplied to a winding device.

Advantageously, during the stranding, the bundle of wires with constant voltage is drawn off the multi-wire coil and, in order to achieve a low wire tensile force, guided in a pulley-like manner via a roller system and an actuating roller of a wire pull brake, the individual wires subsequently being separated out and via their associated dancer storage device guided and stranded as a result of a sliding and rolling movement on a conical deflection roller in a single stranding point in a double twist to the wire strand finished in its structure, the wire strand finished in its structure when two flyers rotating in synchronism with one another pass through at twice the speed of the flyer rotates around itself, the wire strand, if necessary before it is wound up, in order to reduce its internal torsional tension one or more overturning processes and / or a defined increase in tensile force and / or one or more postforming processes and finally fed to a controlled winding device with constant winding force.

An approximately equal length of the wires can also be achieved by bundling the wires running from the stationary processes and possibly drawn to the desired wire diameter by means of the wire pulling device of wires with a speed that allows deformation of the wires in the elastic range, are over-rotated.

In order to implement any combination of wire strands, the wires that run from the multi-wire coil arranged on the coil carrier can be equipped with additional wires and / or wires that run from single and / or multi-wire coils and that are supported on one or more coil carriers , stranded together.

According to a further embodiment of the invention, the individual wires and / or strands are subjected to a preforming before they enter the rope point.

It is also possible to subject the stranded wire strand, in its structure, in the area between the stranding point and the conical deflecting roller to elastic deformation by overturning, if necessary.

In a further embodiment of the invention, this comprises a device for simultaneous winding of a multi-wire spool with several wires, in particular wires with a low plastic deformability, such as steel wires and / or simultaneous unwinding of the wires from such a multi-wire spool for subsequent stranding thereof, to be designed such that the device for winding a multi-wire coil has a winding device and / or for unwinding a multi-wire coil has a stranding device, the winding device having stationary processes for the individual wires, if appropriate a downstream wire drawing device and at least one multi-wire winder with multi-wire coil and the stranding device has at least one unwinding device in the form of a bobbin and one unwinding device, and that each of the wires running from the stationary processes of the winding device between the processes n or, if applicable, the wire drawing direction and the multi-wire winder with the multi-wire spool and each of the wires running from a multi-wire spool is fixed to the unwinding device in the form of the bobbin of the stranding device or in the wire running direction is fixedly assigned behind the bobbin behind the bobbin.

An advantageous embodiment consists in that between the processes or the wire pulling device of the winding device and the dancer storage devices in the wire running direction one after the other an overturning device, a take-off dancer device and optionally guide means and further in the wire running direction behind the dancer storage devices one after the other a laying and a regulated multi-wire winder are arranged with multi-wire coil.

Furthermore, each wire can be assigned its own, separately driven and regulated drawing disk between the processes or the wire drawing device of the winding device and the dancer storage device and, in the wire running direction behind the dancer storage device, a common take-off disk with pressure roller, one after the other Laying and a regulated multi-wire winder with multi-wire coil can be arranged.

It is possible for the wire drawing device to have a multi-wire drawing machine and / or a plurality of individual wire drawing machines. Advantageously, each unwinding device in the form of a bobbin is directly followed by a roller system with an actuating roller for the wire pull brake, each wire running out being guided in one or more turns via this roller system.

The dancer storage devices can be stored separately and have at least one dancer roll that can be loaded with adjustable forces. It is advantageous that a preforming device is optionally arranged between the dancer storage device and the stranding point, and a twisting device is arranged between the stranding point and the conical deflecting roller, and the structure of the stranded wire strand after stranding is carried out by one or more overturning devices before winding and / or post-forming devices and / or a double-disk take-off which generates a defined increase in tensile force.

All deflection and guide rollers, both the winding and the stranding device, via which a plurality of wires which are guided next to one another in an approximately parallel arrangement, preferably have one or more guide grooves with a flat roller cross section.

The stranding device that has the unwinding device can be a double-twist stranding machine according to the “in-out” or “out-in” principle.

With the solution according to the invention it is achieved that, when being wound on multi-wire coils at the same time, the wires to be wound have approximately the same length. The slight differences in wire length that are still present are compensated for when the wires are unwound in the stranding devices. As a result, high-quality stranding is achieved even with highly productive double-strand stranding machines.

The invention is explained in more detail in an exemplary embodiment. In the accompanying drawing:

10g shows the front view of configurations of the cable devices according to FIGS. 3 and 9 with wire and strand runs, FIG. 11 shows the front view of the winding device according to FIG. 2 in a further embodiment.

1 shows a winding device 1 belonging to the device in a preferred embodiment, which has a plurality of stationary processes 2 for wires 3, an overturning device 4, a take-off dancer device 5, one or more guide means 6, dancer storage devices 7, a laying 8 and a regulated multi-wire winder 9 with multi-wire coil 10.

Alternatively, according to FIG. 2, a wire drawing device 11 in the form of a multi-wire drawing machine can be arranged between the stationary outlets 2 and the overturning device 4, with which the individual running wires 3 can be drawn to the desired wire diameter. The wire drawing device 11 can also be a number of individual wire drawing machines exhibit. The stationary processes 2, in turn, can be designed, for example, as coils (FIG. 1) or tangential processes (FIG. 2).

During the winding process, the wires 3 running from the stationary runs 2 are fed directly or via the wire drawing device 11 (FIG. 2) to the overturning device 4 and, as a bundle of wires 3, are jointly subjected to an overturning process, the overturning process being carried out with a Speed takes place which allows the wires 3 to be deformed in the elastic region. It is thereby achieved that the wires 3 have approximately the same lengths when they subsequently enter the trigger dancer device 5, which has a trigger disk 5a and a dancer disk 5b.

The bundle of wires 3 is then fed to the guide means 6. In the present case, the guide means 6 is designed as a guide roller. When leaving the guide means 6, the bundle is unfolded. The individual wires 3 are fed to the respectively associated fixedly arranged dancer storage device 7 and further in an approximately parallel arrangement next to one another via a laying 8 of a laying device of the multi-wire coil 10 of a multi-wire winder 9 which is not known and is not known per se. The dancer memory device 7 assigned to each wire 3 ensures that any different internal tensions and lengths of the wires 3 that may still be present per unit time are compensated for during the winding process of the multi-wire coil 10.

Another embodiment of the winding device 1 is shown in FIG. The winding device 1 also has a wire drawing device 11. The individual wires 3 running from the stationary processes 2 individually pass through the wire drawing device 11 with their drawing dies 40 and the drawing disks 41. The individual wires 3 then run via a separately driven and regulated drawing disk 42 and further via the respective associated dancer storage device 7. It is possible to use the dancer storage device 7 as a control device for the drawing disk 42. The wires 3 are fed to a common take-off wheel 5a with a pressure roller 43. In one or more turns, the wires 3 loop around the take-off disk 5a approximately parallel to one another. The wires 3, which are arranged approximately parallel to one another, are then fed as a bundle via the laying 8 of the laying device to the regulated multi-wire winder 9 and wound there onto the multi-wire coil 10. As a result of the pretreatment, the wires have 3 identical wire lengths. It is also possible to use such a winding device 1 without a wire drawing device 11.

The arrangement of the pressure roller 43 on the take-off disk 5a is necessary in order to prevent the bundle of wires 3 from becoming loose on the take-off disk 5a and thus to ensure a uniform wire pull for all wires 3.

3 shows an embodiment of a stranding device 12 of the device for simultaneous winding of the multi-wire spool 10 with a plurality of wires 3 and / or simultaneous unwinding of the wires 3 from the multi-wire spool 10 thus wound for the subsequent stranding thereof shows. The stranding device 12 has a double-lay stranding machine 12a according to the "in-out" principle, a double-disk take-off 13, one or more overturning devices 15 and post-forming devices 16 arranged in succession in the direction of the wire strand 14 and a regulated winding device 17.

As shown in Fig. 3, the double twist stranding machine

12a a rotating system with a non-rotating bobbin 19. The one with the bundle of approximately parallel juxtaposed wires 3 wound multi-wire spool 10 is arranged in the bobbin 19 within the rotating system. However, a plurality of multi-wire coils 10 and / or individual wire coils can also be arranged in the coil carrier 19.

The coil carrier 19 is via end pivot 19a; 19b, on the central axis of the double twist twisting machine 12a forming the axis of rotation. Due to its own weight, the bobbin 19, as already explained, does not rotate during the stranding process. The end pivot 19a; 19b can be hollow.

Further pay-off coils 10 ′ in the form of multi-wire or single-wire coils can be arranged in front of the bobbin holder 19. Further wires and / or, if appropriate, the core wire 3 'of the stranded wire 14 to be produced are drawn off from the supply coils 10'. This core wire 3 'can also be a core strand consisting of several individual wires. The core wire 3 'runs along the central axis M to the pivot 19a and via a deflection roller 20a to a guide element 21a. The guide element 21a is a component of the flyer 22a, which is arranged in the region of the front end of the coil carrier 19. From there, the core wire 3 'runs in a free flight curve to a guide element 21b of a flyer 22b arranged in the region of the rear end of the coil carrier 19. The core wire 3 'is guided into the area of the multi-wire coil 10 via a deflection roller 20b assigned to the pivot pin 19b.

The guide elements 21a; 21b can be designed as guide rollers or guide nipples. A conical deflection roller 23 is mounted on or in the front pivot 19a in the area of the central axis M. The longitudinal axis of the deflecting roller 23 extends essentially perpendicular to the central axis M. The deflecting roller 23 forms a first deflecting point for that of the multi-wire spool 10 and, if appropriate, further payout spools stripped stranded material. The stranded material consists of the wires 3 and possibly the core wire 3 '.

As shown in FIG. 4, the stranded material runs onto the largest diameter section of the conical deflection roller 23. The stranded material slides off during the deflection, with its own rotation on the jacket of the deflection roller 23, towards the narrower end part. As a result, the stranded material is completely stranded and forms a stranded wire 14. The first and second stranding twists are thereby combined in a stranding point 24 (FIG. 5).

As shown in FIGS. 3 and 5, the wires 3 drawn off as a bundle from the multi-wire spool 10 and, if appropriate, also the wires of further payout spools, here the core wire 3 ¹ of the payout spool 10 ', are guided over a roller system 25. The

Roller system 25 is designed in the form of a block and tackle with an actuating roller 25a and a wire tension brake 26. All of the wires 3 running from the multi-wire coil 10 then run at a small lateral distance from the central axis M to the stranding point 24 and then as a wire strand 14 along the central axis M through the hollow pivot pin 19a to the wider end part of the conical deflection roller 23.

The section between the multi-wire coil 10 and the deflection roller 23 has, as shown in FIGS. 3 and 5, the roller system 25 described above in the downward direction of the stranded material. Dancer storage devices 7 'loaded with adjustable forces are arranged in accordance with the number of running wires 3. Furthermore, a preforming device is optionally provided in a washer 27 and the common stranding point 24 for the first and second stranding twist. A swirl device 28 can also be arranged.

During the stranding, the bundle becomes approximately parallel wires 3 arranged next to one another are drawn off from the multi-wire coil 10 at constant voltage. The bundle is guided over the roller system 25 and unfolded into individual wires 3. The wires 3 are each fed to their own associated dancer storage device 7 'which is arranged in a stationary manner on the coil carrier 19. By means of the dancer storage device 7 ', a tensioning and length-compensating unwinding process of the wires 3 takes place, which has an advantageous effect on the quality of the wire strand 14 to be produced.

6 shows an advantageous embodiment of the dancer memory device 7; 7 'shown in more detail. This has a lever arm 29 with a wire guide roller 30 which is mounted separately and loaded with adjustable forces. The lever arm 29 can be spring-loaded. Another load, for example with weights or pneumatically, is also possible. 5 shows the use of the dancer storage device 7 'in the stranding device 12. 1, 2 and 11, the dancer storage device 7 is arranged in the winding device 1, the wire guide roller 30 executing a vertical movement as a dancer roller.

The preforming of the individual wires 3 by means of the preforming device in the laying disk 27 is necessary in certain materials to be processed, in particular in the case of HT and Ultra-HT wires, so that they retain their position in the stranding assembly. Known and consequently not shown embodiments of preform devices provide preform nipples or preform rollers. The geometrically finished wire strand 14 coming from the stranding point 24 can, depending on the wire material to be processed, be overturned by means of the twisting device 28 (FIG. 5). In this way, each of the individual wires 3 in the twisted strand is given the required length. In this case, there is a plastic deformation. The twist device 28 rotates in the same direction, but at a higher rotational speed than the flyers 22a; 22b of the double twist stranding machine 12a. Depending on the desired stranding structure, the rotational speed of the twisting device 28 is 1.4 to 1.95 times higher than that of the flyers 22a; 22b proved to be advantageous.

The wire strand 14 drawn off from the narrow end part of the deflection roller 23 and now finished in its structure runs according to FIG. 3 to the guide element 31a of the first flyer 22a and from there in a free flight curve via the guide element 31b of the second flyer 22b to one in the Trunnion 19b transverse to the central axis M deflection roller 32. The guide elements 31a; 31b can be designed as guide rollers or as guide nipples. The two flyers 22a; 22b are driven synchronously by a drive motor 33 via known gears, for example toothed belt drives. The conical deflection roller 23 mounted on the pivot 19a rotates together with the flyer 22a about the central axis M. In FIG. 5, the coil carrier 19 with a multi-wire coil 10 and the associated wire pull brake 26 and the roller system 25 are shown in more detail. The wire pull brake 26 is designed as a so-called dancer-controlled brake and has a two-armed pivot lever 26a. The actuating roller 25a, which is wrapped around by the running wires 3, is mounted on one arm of the pivoting lever. A spring element 26b acts on the other arm of the pivoting lever. The arm carrying the actuating roller 25a is connected via a linkage 26c to a brake band 34 provided with brake shoes 35. The brake lining of the brake band 34 presses against the braking surface of a brake disk 36 fastened on the shaft of the multi-wire coil 10. As described above, the wire pull brake 26 is assigned a roller system 25 in the form of a bottle pull. The actuating roller 25a mounted on the swivel lever 26a is at the same time a component of the roller system 25 Wires 3 are fed to the roller system 25 and pass through them in several turns.

By guiding the wires 3 over the roller system 25 in several turns it is achieved that the wire tensile forces can be kept low and constant over the entire coil filling with large coil masses and thus large withdrawal forces. This means that very thin wires 3 can also be processed.

The structure of the wire strand 14, which is already structured when it enters the first flyer 22a, remains in the area of the free flight curve between the two flyers 22a; 22b received. When leaving the double twist stranding machine 12a, the stranded wire 14 is fed to the double-disk take-off 13 via the deflection roller 32 rotating around the central axis M. 7 shows the double-disc trigger 13 in more detail. It has two rollers 13a arranged axially parallel to one another; 13b. The roller 13a can be provided with circumferential grooves 13c, while the roller 13b has a step 13d. The wire strand 14 runs in a number of ordered loops around the two rolls 13a, 13b, the step 13d causing a jump from a smaller to a larger roll diameter. This results in a defined increase in tensile force, by means of which torsional stresses in the wire strand 14 are reduced in cooperation with the overtightening 15.

To further completely reduce internal stresses and to maintain the stranding bandage of the wire strand 14, a post-forming device 16 is arranged in the region of the double-disk take-off 13, as shown in FIG. 3, behind the overturning device 15. The overturning device 15 in turn has one towards the flyers 22a; 22b of the double twist stranding machine 12a in the opposite direction of rotation. Depending on the desired rope structure, the overturning device 15 rotates at a speed of 0.3 to 1.0 times that of the flyers 22a _; 22b. The overturning device 15 is operated by a not shown Drive separately from the double twist stranding machine 12a. This drive is controlled as a function of the drive motor 33 (main drive) shown for the double-twist twisting machine 12a and the double-screen take-off 13 by a regulating and control device (not shown in more detail). The direction of rotation and the speed of rotation of the overturning device 15 are also regulated by the regulating and control device.

The wire strand 14 is fed via deflection rollers 37 to one or more post-forming devices 16 which have at least one row of straightening rollers arranged one behind the other with mutual offset. The mutual relocation of the straightening rollers can be adjusted according to the respective product and operating conditions. The wire strand 14 runs in a wavy path over the straightening rollers, and the resulting bending and flexing effects result in a reduction in tension and position corrections of the wires 3; 3 'of the wire strand 14. The wire strand 15 is then passed over a further deflection roller 37 and the rollers 13a; 13b of the double-disc take-off 13 and a laying device 18 of the regulated and separately driven winding device 17. The stranded wire 14 coming from the double twist stranding machine 12a is guided in the direction of the arrow, along the guide sections a to i.

As described with reference to FIG. 3, the core wire 3 ¹ is drawn off from a payout spool 10 ′ arranged outside the spool carrier 19. However, it is also possible to pull off the core wire 3 ', in a manner known per se, from a further payout spool arranged in the spool carrier 19.

Furthermore, as shown in FIG. 8, all deflecting and guiding rollers over which the wires 3 are guided next to one another in an approximately parallel arrangement can have one or more guiding grooves 38 with a flat roller cross section. The guide grooves 38 ensure approximately orderly parallel guidance of the wires 3 next to one another and in particular prevent loops which would have a considerably disadvantageous effect, in particular in the case of stranding.

9 is a further embodiment of the to

Device belonging stranding device 12 shown. In the stranding device 12, the double-twist stranding machine 12a according to the "in-out" principle is replaced by a double-twist stranding machine 12b according to the "out-in" principle. Consequently, the multi-wire coils 10 used are not arranged inside but outside the rotating system of the double-twist twisting machine 12b.

In this case, the multi-wire coils 10 are each wound with a bundle of wires 3 arranged parallel to one another and are mounted in a coil carrier 19 which is arranged in a stationary manner outside the double-twist twisting machine 12b. According to FIG. 9, three multi-wire coils 10 are arranged in the coil carrier 19, from each of which three wires 3 are drawn off. Another multi-wire coil 10 'is assigned to the multi-wire coils 10. A core wire 3 'or a core strand, which consists, for example, of three individual wires, can be drawn off from the winding spool 10'.

This system configuration is suitable for the production of wire strands 14 of the design 1 + 9 or 3 + 9. In the training 1 + 9 the wire strand 14 consists of a core wire 3 'and nine wires 3. While in the training 3 + 9 the wire strand 14 is formed of a core strand with three individual wires and nine wires 3.

For stranding, the individual wires 3 and the core wire 3 'are pulled off with constant tensile force. In the wire running direction, the bundle of wires 3 arranged approximately parallel to one another is separated by the respective multi-wire coil 10 coming, guided over the roller system 25 with the wire brake 26. Subsequently, each individual wire 3 is guided over its own dancer storage device 7 'which is arranged in a stationary manner on or behind the coil carrier 19. Subsequently, the wires 3 are fed to the stranding point 24 via the washer 27, wherein the wires 3 can pass through a preforming device. The core wire 3 'is in turn also guided over an associated roller system 25 with a wire tension brake 26, but then runs directly over the washer 27 to the stranding point 24. The stranded material, consisting of wires 3 and the core wire 3', becomes subsequently fed to the rotating system of the double twist stranding machine 12b. The actual stranding process takes place in such a way that the stranded material is guided in the first deflection point via a deflecting roller 20a which is arranged in the first pivot 19a and also rotates, and further over a guide element 31a of the associated flyer 22a. In a free flight curve, the guide element 31b of the synchronously rotating second flyer 22b is reached and from there it is fed to the conical deflection roller 23 which is arranged in the second pivot 19b and rotates with it. The stranded material runs on the largest on the conical deflection roller 23

Diameter section on. The stranded material slides during the deflection, with its own rotation on the jacket of the deflecting roller 23, towards the smaller end part. As a result, the stranded material undergoes a complete stranding and forms the wire strand 14. The first and second stranding twists are thereby combined in the stranding point 24. Coming from the conical deflection roller 23, the stranded wire 14 is fed to the controlled winding device 17 with the laying device 18 via a double-disk take-off 13, a subsequent overturning device 15 and a post-forming device 16. The double-disk take-off 13, the overturning device 15, the post-forming device 16 and the winding device 17 with the laying device 18 are, in a manner known per se, arranged in a stationary manner in a bobbin 39. The coil carrier 39 is indeed on the end pivot 19a; 19b rotatably, however due to its own weight, it does not turn during the stranding process.

As shown in FIG. 9, there is also the possibility of arranging a twisting device 28 between the stranding point 24 and the first deflecting roller 20a, outside the rotating system of the double-twist twisting machine 12b. Further explanations on the above-mentioned devices are superfluous, since their more detailed design and function correspond to the devices of the same name and the same designation and already described for the double-twist twisting machine 12a.

FIGS. 10a to 10g show configurations of the stranding device 12 with a wire and strand run. However, the scope of the invention is not restricted to these examples.

FIGS. 10a to 10d show stranding devices 12 with double twist twisting machines 12a according to the "in-out" principle.

According to FIG. 10a, a multi-wire coil 10 is arranged in the rotating system of a double-twist twisting machine 12a, which according to the programs 1x2; 1x3; 1x4 or 2 + 2 is wound with a bundle of two to four individual wires 3 arranged parallel to one another. The bundle of wires 3 is pulled off and unfolded with constant tensile force. Following this, the individual wires 3 are guided and stranded over their respective dancer storage devices 7 '. After the wire strand 14, which is finished in its structure, is subjected to a defined increase in tensile force and one or more overturning and post-forming processes, as already described, in order to reduce its internal tensions, the finished wire strand 14 is fed to the controlled winding device 17 with a constant winding force. In FIG. 10b, two multi-wire coils 10 for three wires 3 each are arranged in the rotating system in accordance with programs 1 + 6 or 3 + 6. Arranged in front of the rotating system is a payout spool 10 'with a core wire 3' or a core strand consisting of three wires stranded together. The core wire 3 'or the core strand runs into the rotating system and is stranded with the wires 3 running from the multi-wire coils 10 arranged in the coil carrier 19.

In FIG. 10c, according to the programs 1 + 6 or 3 + 6 of the pay-off spool 10 ', a multi-wire spool 10 with six wires 3 arranged in the rotating system is assigned. Instead of the core wire 3 ', a core strand, consisting of three wires stranded together, can be wound on the winding spool 10'. The process sequence is described above.

In FIG. 10d, according to the programs (1 + 6) +12, the pay-off spool 10 'in the rotating system is assigned four multi-wire spools 10, each with three wires 3. Instead of a core wire 3 ', a core strand is provided. It corresponds to training 1 + 6.

Figures 10 to 10g show stranding devices 12 with double twist twisting machines 12b according to the "out-in" principle.

According to FIG. 10e, both the payout spool 10 'for the core wire 3' and the multi-wire spool 10 for the wire 3 are arranged outside the rotating system. According to programs 1 + 6, a bundle of six wires 3 arranged approximately parallel to one another is arranged on the multi-wire coil 10, which bundle is drawn off with constant tensile force. These wires 3 are folded apart and each supplied to their dancer storage device 7 'and together with the core wire 3' in the stranding point 24 to the wire strand 14, as described above, stranded, optionally guided and twisted over a twisting device 28.

10f shows a double-twist stranding machine 12b for a program of training 1 + 6, three wires 3 each being drawn off from two multi-wire spools 10 and stranded with a core wire 3 'running out from the payout spool 10'.

According to FIG. 10g, for a parallel configuration, for example 1 + 9 + 9, three wires 3 are drawn off from six multi-wire coils 10 and fed to the stranding point 24 with the core wire 3 'running from the payout coil 10'.
