Description

Method and apparatus for simultaneously winding a plurality of filaments into a multifilament spool and/or for simultaneously unwinding the filaments from a multifilament spool thus wound for their subsequent stranding

The invention relates to a method and a device for winding and/or unwinding a multifilament reel, wherein a plurality of filaments, in particular filaments with poor plastic deformability such as steel wires, are simultaneously wound on a multifilament reel and/or The filament thus wound is simultaneously unwound in the twister and then twisted.

In practice methods are used for the production of stranded ropes which involve three stages, namely drawing, conveying and twisting, and the associated winding and unwinding processes.

It is known from DE 21 39 244 A1 to assign a puller with a spare reel to several wire drawing machines, wherein the number of wire drawing machines corresponds to the number of strands of the twisted rope or rope to be produced. The finished yarns are wound on a common spare reel at the same time. These filaments are then drawn out again simultaneously from this fixedly arranged backup reel and fed to the stranding machine.

It is known from DE 39 22 974 A1 to simultaneously draw a plurality of wires by means of a wire drawing machine and feed them all or divided into components to one or more winding machines, where some wires form bundles together or as A single filament is wound.

Using this method should achieve the purpose of increasing productivity in the silk production and silk processing industry. For wires, especially wires with poor plastic deformability such as steel wires, each wire of the bundle is affected by different winding parameters during the winding process. Such influences result, for example, from the different surface structures of the individual filaments in the coiling region on the reel. A different length and stress state is thus also created per unit of time and per filament. If the thus wound multi-filament reel is used in a stranding machine as an unwinding reel, it cannot be ensured that each filament remains of the same length and thus cannot guarantee a high quality stranding of these filaments into a stranded rope. Such wound wire bundles cannot meet the requirements for further high-quality twisting on the two-for-one twisting machine known in mass production as known from EP 0 563 586.

The object of the present invention is to create a method and a device for winding and/or unwinding a multifilament reel, wherein a plurality of filaments, especially filaments with low plastic deformability such as steel wires, are simultaneously wound on a multifilament On the spool and/or the silk wound up in this way is simultaneously uncoiled and then twisted in the twister, and these threads can be produced in large quantities with high quality, that is, while ensuring the same length ratio in the thread layer according to the invention. According to the principle of multi-filament stranding, they are twisted together in the double twister on the stranding machine.

The measures taken for this purpose according to the invention are that during the winding process in the winding machine, single wires are discharged from the stationary uncoiler and fed into respective compensating accumulators, and a plurality of such wires are used as a A bundle of filaments in nearly parallel juxtaposition is wound on a common multifilament reel; The uncoiler of the reel frame receives, and the individual filaments are fed to the stranding process through their respective compensating accumulators.

In a further development of the invention, the individual filaments are drawn from the stationary uncoiler and drawn into the required filaments by means of a filament drawer in the form of a multifilament drawer and/or a plurality of monofilament drawers path, and then sent to the respective compensating storage.

In order to obtain the same filament length on the multi-filament reel, it is stipulated that the individual filaments discharged from the fixed uncoiler are combined into a bundle of filaments directly before reaching the compensating storage. This bundle is subjected to an over-coiling process. In case the tow is guided by a draw compensator and if necessary by a suitable guide mechanism, then the tow is separated and all the filaments flow respectively via the respective compensating reservoir and further via a laying device as substantially parallel The bundles of parallel yarns are fed into an adjusted multi-filament winder, where they are wound into multi-filament spools.

In addition, it is also possible to guide the individual filaments unwound from the stationary uncoiler directly before the compensating accumulator via separately driven and adjusted drawing discs, and then feed them via the respective compensating accumulator to a common belt pulley In this case, the filaments are wound around the pulling disk one or more turns in generally parallel parallels and then fed into the adjusted multi-filament take-up as a bundle of generally parallel parallel filaments, where Wind into a multi-filament spool.

According to another embodiment of the present invention, the multi-filament reel wound with the bundle composed of substantially parallel parallel filaments is contained in the unwinder designed as a reel frame of the twister, and the tow is used during the twisting process. Constant tension draws and separates each filament, each filament is guided via its own compensation reservoir, and finally all filaments to be twisted are twisted into a structurally completed strand in a single twisting point in the twister Close the rope, and enter a winder after passing through two flyers that rotate synchronously with each other.

Advantageously, the bundle of wires is pulled out from the multi-filament reel with constant tension during the twisting process and is guided in groups of pulleys with a small wire tension via the pulley system and the steering wheel of the wire pulling brake, and then The individual filaments are separated from each other and flow through their associated compensating reservoirs, and due to the sliding and downward movement on a conical guide wheel, are stranded in a single twisting point in the twister. In terms of its structure The completed strand rope, which in its construction is completed, turns around itself at twice the speed of the flyer when passing two flyers rotating synchronously with each other, if necessary before the strand is wound In order to reduce the internal torsional stresses, it is subjected to one or more overtightening operations and/or a defined tension increase and/or one or more post-setting operations, and finally the adjusted winder is fed with a constant winding force.

Filaments of approximately the same length can also be obtained by unwinding from a stationary uncoiler and, if necessary, drawing the desired diameter of the wire by means of a wire puller as a bundle of filaments, in a manner that allows the filament to deform within the elastic range. The rotation speed is too tight.

In order to realize any combination of twisted ropes, the wires released from the multi-filament reel mounted on the reel frame are twisted together with other wires and/or twisted wires released from the monofilament and/or multi-filament reels, Said monofilament and/or multifilament spools are mounted on one or more spool stands.

According to a further refinement of the invention, the individual filaments and/or strands undergo a deformation before entering the twisting point.

It is also possible to subject the structurally completed twisted rope to an elastic deformation in the region between the twisting point and the conical guide pulley by overtightening.

Another design of the invention includes a method for simultaneously winding a plurality of wires, especially wires with poor plastic deformability, such as steel wires, into a multi-filament reel and/or simultaneously unwinding from a multi-filament reel thus wound. This multifilament is used for their follow-up stranding equipment design, and equipment has a winding machine for winding multi-filament reel and/or a twister for unwinding multi-filament reel, wherein, winding The machine has a fixed uncoiler for individual filaments, if necessary a wire drawer downstream of the uncoiler and at least one multifilament take-up with a multifilament reel, and the twister has at least one reel stand in the form of uncoiler and a winder; and, for each wire released from the fixed uncoiler of the winding machine between the uncoiler or, if necessary, the drawer, and the multifilament take-up with a multifilament spool and For each thread unwound from the multifilament reel, a compensating store is provided, which is attached to the unwinder of the bobbin frame in the form of a twister or behind the bobbin frame in the direction of flow of the threads.

An advantageous configuration is that between the uncoiler or the wire drawer of the winding machine and the compensating accumulator, an overtensioner, a pull compensator and, if necessary, a guiding mechanism are arranged sequentially along the flow direction of the wire, And further along the flow direction of the silk, a wire laying device and an adjusted multifilament take-up device with a multifilament reel are arranged sequentially after the compensating type storage.

In addition, it is also possible to provide separately driven and adjusted drawing discs for each wire between the wire drawer and the compensation storage of the uncoiler or winding machine, as well as behind the compensation storage in the flow direction of the wires. , sequentially set up a public pulling disc with pressure roller, wire laying device and adjusted multifilament take-up device with a multifilament spool.

A drawer can have one multifilament drawer and/or multiple monofilament drawers. Expediently, directly downstream of each unwinder in the form of a reel stand, there is a pulley system with a thread draft brake actuating wheel, by means of which each unwound thread is guided along one or more turns.

The compensating stores can be mounted individually and have at least one compensating wheel which can exert an adjustable force.

Advantageously, if necessary, a preformer is arranged between the compensating reservoir and the twisting point, and a twister is set between the twisting point and the conical guide wheel, and, after twisting, the stranding whose structure has been completed Before winding, the tie rope is guided by one or more overtensioners and/or post-sizers and/or a double-wheel puller which results in a defined tension increase.

Preferably all winders and twisters have deflection and deflection pulleys through which a plurality of wires are guided substantially parallel and side by side, and which have one or more guide grooves and flat pulley cross-sections.

A twister with an unwinder can be a two-for-one twister based on the "in-out" or "out-in" principle.

With the solution according to the invention it is achieved that the threads to be wound have approximately the same length during simultaneous winding on a multi-filament reel. The small difference in filament length that still exists is compensated when the filament is unwound in the twister. So even high-quality twisting can be obtained in mass-produced two-for-one twisting machines.

The invention is explained in detail below with the aid of examples. In the accompanying drawings it is indicated:

FIG. 11 is a front view of another embodiment of the winding machine according to FIG. 2 .

Figure 1 shows a preferred embodiment of a winding machine 1 belonging to the device, which has a fixed uncoiler 2 for a plurality of wires 3, an overtensioner 4, a pull compensator 5, one or more guide mechanisms 6 , compensating storage 7, a laying device 8 and an adjusted multifilament reel 9 with a multifilament reel 10.

According to another kind of optional scheme of Fig. 2, can be provided with a wire drawing device 11 that is multi-filament drawing machine on the form between fixed uncoiler 2 and over-tensioner 4, by means of it can draw a The silk 3 that root sends out is stretched to required silk diameter. The wire drawing unit 11 may also have some monofilament drawing machines. The stationary uncoiler 2 itself can be designed, for example, as coils ( FIG. 1 ) or as a tangential uncoiler ( FIG. 2 ).

During the winding process, the wire 3 released from the fixed uncoiler 2 is directly or via the wire drawing device 11 (Fig. 2) input into the over-coiler 4, and as a bundle of wire 3, it undergoes an over-coil process together, wherein, The overtightening process is carried out at a rotational speed that allows deformation of the wire 3 in the elastic range. This results in approximately the same length of the wires 3 when they subsequently enter the pull compensator 5 with the pull disc 5 a and the compensating disc 5 b.

Next, the bundle of wires 3 is fed into the guide mechanism 6 . In this example the guide is designed as a guide groove. When the tows leave the guiding mechanism 6, they are separated from each other, and each filament 3 is input into a fixedly arranged compensating storage 7 assigned to it, and is further arranged in a substantially parallel manner through the laying of known laying equipment not shown in detail in the figure. The wire device 8 is fed into the multi-filament reel 10 of the multi-filament winder 9 . By means of the compensation accumulator 7 assigned to each filament 3 , it is ensured that any internal stresses and length differences of the filaments 3 that may still exist per unit of time are compensated during the winding process of the multifilament reel 10 .

Another embodiment of the winding machine 1 is shown in FIG. 11 . The winding machine 1 also has a wire drawing device 11 . The individual filaments 3 drawn off from the stationary uncoiler 2 each pass through a wire drawer 11 with its drawing stone 40 and drawing disc 41 . The individual filaments 3 then flow via the independently driven and adjusted stretching discs 42 and further via the associated compensating reservoir 7 . The compensating accumulator 7 can be used as an adjuster for the tension disc 42 . These wires 3 are fed into a common pulling reel 5 a with pressure rollers 43 . The wires 3 are generally parallel and juxtaposed around the pulling disc 5a in one or more turns. Then, the wires 3 parallel and parallel are input into the adjusted multi-filament winder 9 as a tow through the wire laying device 8 of the wire laying device, and are wound on the multi-filament reel 10 there. In this case, the pretreatment causes the threads 3 to have the same thread length. It is also possible to use such a winding machine 1 without the wire puller 11 .

It is necessary to arrange a pressure roller 43 at the pulling disc 5a to prevent the bundle of wires 3 from loosening on the pulling disc 5a and thus to ensure a uniform wire tension for all the wires 3 .

FIG. 3 shows an embodiment of a twister 12 of a device for simultaneously winding a plurality of filaments on a multifilament reel 10 and/or simultaneously unwinding these filaments 3 from a multifilament reel 10 thus wound. For their subsequent twisting, the twister 12 has a two-for-one twisting twister 12a according to the "in-out" principle, a double-wheel puller 13, and one or more transitions arranged in sequence along the direction of flow of the twisted rope 14. Tensioner 15, postformer 16 and an adjusted winder 17.

As shown in FIG. 3, the two-for-one twisting machine 12a has a rotating system having a reel frame 19 which does not rotate with it. A multi-filament reel 10 , on which a bundle of filaments 3 are wound in substantially parallel juxtaposition, is mounted inside the system rotating on a reel frame 19 . However, a plurality of multifilament reels 10 and/or monofilament reels can also be arranged on the reel stand 19 .

The reel stand 19 is mounted via end-side journals 19a; 19b on the center line forming the axis of rotation of the two-for-one twisting machine 12a. Due to its own weight, the reel stand 19 does not rotate with it during the stranding process, as already explained. The end-side journals 19a; 19b can be hollow.

A further take-off reel 10 ′ in the form of a multifilament or monofilament reel can be arranged upstream of the reel stand 19 . Further threads and/or core wires 3' of the stranded rope 14 to be produced are drawn off from the uncoiling reel 10'. This core wire 3' can likewise be a stranded core wire consisting of a plurality of monofilaments. The core wire 3' flows along the central line M toward the journal 19a, and flows toward a guide member 21a through a guide wheel 20a. The guide 21 a is part of a flyer 22 a which is arranged in the region of the front end of the roll stand 19 . From there, the core wire 3' flows along a free flight curve to the guide 21b of the flyer 22b arranged in the region of the rear end of the reel frame 19. The core wire 3' is guided into the region of the multifilament reel 10 via a guide wheel 20b assigned to the journal 19b.

The guide elements 21a; 21b can be designed as guide wheels or guide sleeves. The tapered guide wheel 23 is installed on the front journal 19a or in the front journal 19a in the centerline M area. The longitudinal axis of the guide wheel 23 runs substantially perpendicular to the center line M. As shown in FIG. The deflection pulley 23 forms the first deflection point for the strand material fed off from the multifilament reel 10 and, if applicable, from other unwinding reels. The strand material consists of threads 3 and optionally core wires 3'.

As shown in FIG. 4 , the twisted material is coiled at the large diameter portion of the conical guide wheel 23 . The twisted material slides toward the narrower end direction while rotating on the guide wheel 23 overcoats when turning. Therefore, this twisted material undergoes a sufficient stranding and forms the strand 14 . The first and second strands are thus unified at the stranding point 24 (FIG. 5).

As shown in FIGS. 3 and 5 , as a bundle of filaments 3 drawn from the multifilament reel 10 and possibly also filaments of other uncoiled reels, here the core wire 3 ′ of the uncoiled reel 10 ′, is passed through a pulley system 25 guide. This pulley system 25 is designed in the form of a pulley block with a steering wheel 25 a and a wire pulling brake 26 . All the filaments 3 drawn from the multi-filament reel 10 flow to the stranding point 24 at a small lateral distance from the center line M, and then, as strands 14, pass through the hollow journal 19a along the center line M to the conical guide wheel. 23 at the wider end.

As shown in Fig. 3 and Fig. 5, the part between the multi-filament reel 10 and the guide wheel 23 has the above-mentioned pulley system 25 along the leading-out direction of the twisted material. Compensating accumulators 7' are provided which apply an adjustable force according to the number of drawn wires 3 . Furthermore, a preformer and a common laying point 24 for the first and second laying strands are optionally provided in the positioning disc 27 . Furthermore, a twister 28 can be provided.

During the stranding process, a bundle of substantially parallel juxtaposed filaments 3 is withdrawn from the multifilament reel 10 with constant tension. The filament bundles are guided by a pulley system 25 and separated from each other into individual filaments 3 . The wires 3 are delivered to their respective compensating accumulators 7 ′ which are fixedly mounted on the reel stand 19 . With the aid of this compensating accumulator 7 ′, an unwinding process in which the tension and length of the thread 3 are compensated per unit of time is achieved, which has a favorable effect on the quality of the strand 14 to be produced.

FIG. 6 shows in detail a preferred embodiment of the compensating store 7; 7'. It has an independently supported and adjustable force loaded lever arm 29 and godet 30 . The lever arm 29 may be spring loaded. However, other loading methods such as gravimetric or pneumatic are also possible. FIG. 5 shows the compensating store 7 ′ acting in the twister 12 . In FIGS. 1 , 2 and 11 this compensating accumulator 7 is arranged in the winding machine 1 , wherein the godet 30 executes a vertical movement as a compensating wheel.

For some materials to be processed, such as high tensile strength (HT) and ultra-high tensile strength wires, it is necessary to preform each wire 3 by means of a preformer in the positioning disc 27, in order to make them twisted maintain its position in the structure. Known and therefore not specified embodiments of preformers use preforming sleeves or preforming wheels. The geometrically completed twisted rope 14 from the twisting point 24 can be over-tightened by means of a twister 28 (as in FIG. 5 ) depending on the material of the thread to be processed. In order to make each wire 3 in the twisted structure obtain the required length. In this case plastic deformation occurs. The twister 28 rotates in the same direction, but at a high rotational speed as the flyers 22a; 22b of the two-for-one twisting machine 12a. Depending on the desired twisting configuration, it has proven to be advantageous for the twister 28 to rotate at a rotational speed which is 1.4 to 1.95 times higher than the flyer 22a; 22b.

The twisted rope 14, whose structure has now been completed, leads from the narrower end of the guide pulley 23, flows according to FIG. The guide 31b of 22b flows to a guide wheel 32 mounted transversely to the center line M in the journal 19b. The guide elements 31a; 31b can be designed as guide sleeves or guide wheels. The two flyers 22a; 22b are jointly driven synchronously by a drive motor 33 via a known transmission, for example a toothed belt transmission. The tapered guide wheel 23 mounted on the journal 19a rotates around the centerline M together with the flyer 22a. FIG. 5 shows the bobbin stand 19 and the multifilament reel 10 with the associated thread pulling brake 26 and the pulley system 25 in detail. The wire pulling brake 26 is designed as a so-called compensation control type brake and has a double-armed rotary lever 26a. An arm of the revolving lever is equipped with a steering wheel 25a that is wound by the wire 3 that is released. On the other arm of the swivel lever a spring element 26b acts. The arm on which the steering wheel 25a is mounted is connected via a link 26c to a brake band 34 provided with a brake caliper 35 . The brake pad linings of the brake band 34 are pressed against the braking surface of a brake disc 36 fixed on the shaft of the multifilament reel 10 . As already mentioned above, a pulley system 25 in the form of a block and block is assigned to the wire pulling brake 26 . The steering wheel 25 a , which is supported on the pivot lever 26 a , is at the same time a component of the pulley system 25 . The wire 3 is delivered to the pulley system 25 via the steering wheel 25a and passed through this pulley system in multiple turns.

By guiding the wire 3 in multiple turns via the pulley system 25 , it is possible to keep the tension of the wire low and constant along the entire reel load even with large reel loads and thus high discharge forces. Thus, very fine threads 3 can also be processed.

The stranded rope 14 , whose structure has been completed when it enters the first flyer 22 a , retains its structure in the region of the free flight curve between the two flyers 22 a ; 22 b. When the twisted rope 14 leaves the two-for-one twisting machine 12a, it enters the double-wheel puller 13 through the guide wheel 32 rotating around the center line M. Figure 7 shows the dual wheel retractor 13 in detail. It has two rollers 13a; 13b arranged axially parallel and at a distance from each other. Wherein, the roller 13a can be formed with a circumferential groove 13c, and the roller 13b has a step 13d. The twisted rope 14 flows successively around the two rollers 13a; 13b in multiple turns, the step 13d causing a sudden change in diameter of the rollers from the smaller to the larger. A defined tension increase is thereby achieved, which, in combination with the cooperation of the overtensioner 15 , reduces the torsional stress in the hinged rope 14 .

In order to further sufficiently reduce the internal stresses and to maintain the twisted structure of the twisted rope 14 , as shown in FIG. 3 , an afterformer 16 is provided behind the overtensioner 15 in the region of the double puller 13 . The overtensioner 15 itself has an opposite direction of rotation to the flyers 22a; 22b of the two-for-one twisting machine 12a. Depending on the desired stranding configuration, the overtensioner 15 rotates at 0.3 to 1.0 times the rotational speed of the flyers 22a; 22b. The overtensioner 15 is driven by a drive not further shown in the figure that is independent of the two-for-one twister 12a. The adjustment of this drive takes place by means of the indicated drive motor 33 (main drive) for the two-for-one twisting machine 12a (main drive) and the double pulley puller 13 by means of an adjustment and controller not further illustrated. The adjustment of the rotation direction and the rotating speed of the over-tensioner 15 is also completed by this adjustment and the controller.

The strands 14 are fed via guide pulleys 37 to one or more postformers 16, which have at least one row of correction rollers arranged continuously and offset from one another. The misalignment of the correction rollers can be adjusted according to specific product conditions and working conditions. The strand 14 runs along a corrugated track over the correcting rollers, and through the bending and pressing effects that occur in this case, a stress reduction and position correction of the strands 3; 3' of the strand 14 are achieved. Then, the twisted rope 14 is delivered to the adjusted and independently driven winder 17 via another guide wheel 37 and the roller 13a of the double-wheel puller 13; 13b and the laying device 18. The twisted rope 14 from the two-for-one twisting machine 12a is guided along the guide sections a to i in the direction of the arrow.

As already explained with reference to FIG. 3 , the core wire 3 ′ is drawn from the unwinding reel 10 ′ arranged outside the reel stand 19 . However, the core wire 3 ′ can also be withdrawn in a known manner from another unwinding reel arranged in the reel stand 19 .

Furthermore, as shown in FIG. 8 , all deflection and guide wheels that guide the wires 3 arranged substantially parallel can also have one or more guide grooves 38 with a flat roller section. The guide grooves 38 ensure that the wires 3 are guided side by side, approximately one behind the other, and in particular prevent the formation of loops, which would otherwise cause serious disadvantages, especially for the stranding process.

FIG. 9 shows another embodiment of the twister 12 belonging to this device. In this twister 12, the two-for-one twisting machine 12a based on the "in-out" principle is replaced by the two-for-one twisting machine 12b based on the "out-in" principle. As a result, the multifilament spool 10 used is not housed inside the rotation system of the two-for-one twister 12b, but is housed outside.

In this case, the multifilament reel 10 is always wound up in bundles of filaments 3 arranged parallel to one another and housed in a reel frame 19 which is fixedly arranged outside the two-for-one twisting machine 12b. According to FIG. 9 , three multifilament reels 10 are arranged in the reel stand 19 , from which three filaments 3 are each drawn out. A further take-off reel 10 ′ is assigned to the multifilament reels 10 . A core wire 3' or a stranded core wire, which for example consists of three individual wires, can be drawn off from the uncoiling reel 10'.

This equipment configuration is suitable for the production of stranded ropes with a structure of 1+9 or 3+9. When the structure is 1+9, the twisted rope 14 is composed of one core wire 3 ′ and nine wires 3 . In the case of structure 3+9, however, the twisted rope 14 consists of a twisted core wire consisting of three monofilaments and nine wires 3 .

For twisting, the individual filaments 3 and core wires 3' are pulled out with the same tension. In the direction of the flow of the wires, the bundle from the associated multi-filament reel 10 consisting of substantially parallel juxtaposed wires 3 is guided by a pulley system 25 with a wire pulling brake 26 . Each thread 3 is then guided through a respective compensating store 7 ′ which is fixedly mounted on or behind the reel stand 19 . The wire 3 is then fed into the stranding point 24 via the puck 27, in which case the wire 3 can pass through the preformer. The core wire 3 ′ itself is likewise guided via an associated pulley system 25 with a wire pulling brake 26 , but then flows directly via the positioning disc 27 to the twisting point 24 . The stranding material consisting of filaments 3 and core wires 3' is then fed into the rotary system of the two-for-one twisting stranding machine 12b. The actual stranding process takes place in that the stranding material is guided at the first deflection point by a guide wheel 20a which is arranged in the first journal 19a and rotates therewith, and further via the guide 31a of the associated flyer 22a guide. It follows the free flight curve to the guide 31b of the second flyer 22b rotating synchronously, and from there to the conical guide wheel 23 which is arranged in the second journal 19b and rotates with it. Stranding material rolls on the tapered guide wheel 23 at the large diameter part of the guide wheel 23 . The strand material slides towards the narrower end by self-rotation on the outer surface of the guide wheel 23 while turning. Therefore, the strand material undergoes a sufficient stranding and forms the strand 14 . The first and second strands are thus unified at the stranding point 24 . The twisted rope 14 from the tapered guide pulley 23 is transported to the winder 17 of the belt laying device 18 adjusted through the double-wheel puller 13, the downstream over-tightener 15 and the post-former 16. The two-wheel puller 13, the overtensioner 15, the postformer and the winder 17 with the laying device 18 are fixedly mounted in a spool frame 39 in a known manner. Although the reel stand 39 is mounted rotatably on the end-side journals 19a; 19b, it does not rotate with it during the twisting process due to its own weight.

As shown in FIG. 9 , there is also the possibility of providing a twister 28 between the twisting point 24 and the first deflection pulley 20 a outside the rotation system of the two-for-one twisting machine 12 b. A further description of the above-mentioned devices is superfluous, since their detailed construction and mode of operation are the same as those described in the text and diagrams and described in conjunction with the two-for-one twisting machine 12a.

10a to 10g show the configuration of the twister 12 and the course of the wires and strands. However, the scope of the present invention is not limited by these examples.

10a to 10d show a twister 12 according to the "in-out" principle with a two-for-one twist twister 12a.
