Device and method for melt-spinning, drawing off, processing and winding up several synthetic threads The invention relates to a device for melt-spinning, drawing off, processing and winding up several synthetic threads, according to the preamble of claim 1, and to a method for melt-spinning, drawing off, processing and winding up several synthetic threads. A generic device and generic method are known, for example, from DE 44 16 136 Al. In the known device and the known method, a plurality of spinnerets are held in an arrangement in row form in a spinning apparatus. A multiplicity of filaments are extruded as a filament bundle for each of the spinnerets and are cooled by cooling medium by means of a cooling apparatus arranged below the spinneret. After the cooling of the filaments, the filament bundle produced per spinneret is consolidated by means of a preparation apparatus. In this case, cohesion between the filaments to form a thread is achieved by means of a preparation agent. The threads are continuously drawn off from the spinnerets jointly as a thread bundle by a draw-off member arranged below the cooling apparatus and, after processing, are wound up in each case into bobbins. Since the guidance distance and the processing distance between the threads during draw-off and processing are substantially smaller than the thread distance in the spinning apparatus, the threads have to be deflected very sharply and brought together during the transition from the spring apparatus to the draw-off member. The deflection of the threads is in this case dependent on the distance between the threads in the spinning apparatus and on the number of threads spun next to one another in parallel. In this case, care must be taken to adhere to maximum permissible deflection angles, so as not to obtain excessive looping differences in thread guidance, particularly the outer threads, which necessarily lead to physical differences in the threads produced. Such permissible deflections in the range of less than 7° can be reduced appropriately only by means of a correspondingly long zone between the spinning apparatus and the draw-off member. In practice, however, it is desirable to have as small a distance as possible between the points of convergence of the filament bundles and the position of the draw-off member, and therefore a thread guidance with different loopings when the thread bundle is brought together can scarcely be avoided. Furthermore, there is the desire to keep the overall height of the plant limited for reasons of cost and of handling. This presents the problem, however, that the threads, when they run into the processing member, are exposed to uneven conditions in terms of thread tension and thread termination. The object of the invention is to provide a device and a method for melt-spinning, drawing off and winding up several synthetic threads, of the type initially mentioned, in which the threads spun in parallel, despite being brought together to a narrower thread distance, can be guided as far as possible under uniform conditions. The object of the invention is likewise to develop a generic device and a generic method such that, even in the case of a multiplicity of threads spun in parallel, a thread guidance for the implementation of compact forms of construction of spinning plants is possible. A further aim of the invention, when the multiplicity of spinnerets are used, is to implement as small deflection angles as possible during the transition from a spinning apparatus to a processing apparatus. The object is achieved, according to the invention, by means of a device for melt-spinning, drawing off, processing and winding up several synthetic threads, having the features of claim 1, and by means of a method for melt-spinning, drawing off, processing and winding up several synthetic threads, having the features of claim 16. The invention is distinguished in that individual spun threads are brought together in a plurality of steps into a common thread bundle to be processed. For this purpose, a plurality of draw-off members are provided below the cooling apparatus, each of the draw-off members being assigned a group of spinnerets. Thus, advantageously, the plurality of spun threads are divided into two or more groups which are drawn off in each case by separate draw-off members. The draw-off members cooperate with the following processing member in such a way that, after the groups of threads have been drawn off, all the threads can be guided jointly as a thread bundle through the processing member. An essential advantage of the invention is that, even in the case of a multiplicity of simultaneously spun threads, the distance between the points of convergence, arranged essentially at one level, of the filament bundles and the position of the draw-off members can be reduced to a technically implementable minimum distance. The point of convergence of a filament bundle is in this case that position in the thread run of a thread in which the filament bundle is brought together to form the thread. The zone between the points of convergence of the filament bundles and the positions of the draw-off members is traversed by the threads obliquely with respect to one another, so that this zone is not suitable for the collective processing of the threads and therefore, according to the invention, can have a particularly short design. In order to obtain as far as possible uniform deflections and loopings within the group of threads, according to an advantageous development of the invention the draw-off members are preferably arranged symmetrically below the respectively assigned groups of spinnerets. In a further preferred development of the invention, the threads, after extrusion, are guided in a common spinning plane and, for processing, into a processing plane oriented essentially orthogonally to the spinning plane. In this context, the thread run plane which is predetermined by the spinnerets of the spinning apparatus is designated as the spinning plane. The processing plane is the common thread run plane of all the threads which is defined by the processing member. This affords additional freedoms in the arrangement of the draw-off members which may guide the groups of threads either parallel to the spinning plane or parallel to the processing plane or in an intermediate plane. In this case, the draw-off members preferably precede the processing members in such a way that each thread can be guided with identical thread loopings. High uniformity in the production of the synthetic threads is thus ensured. In order to allow a parallel run-in of the groups of threads in the draw-off members, each draw-off member is advantageously preceded by a collective thread guide, by means of which the threads can be guided from a spacing distance between the spinnerets into a preferred narrow guide distance. So that intensive thread strength prevails on the thread particularly for the processing of the threads, according to a preferred development of the invention it is proposed to arrange a pretangling apparatus in each case between the collective thread guides and the draw-off members. The preparation application which is lost or is uneven because of the deflection can thus be compensated or equalized. The thread tension before the run onto the draw-off member on the threads running in parallel is likewise equalized. The draw-off members are preferably formed in each case by a driven galette, the galette drives of the galettes being controllable synchronously. In order as far as possible to obtain no differences in the guidance of the groups of threads, the galette drives of the galettes are advantageously controlled by means of a group converter. It is also possible, however, for the galettes to be assigned in each case an overrun roller, so that the threads loop around the galettes and the overrun roller several times. Even higher draw-off forces for drawing off the respective groups of threads can consequently be achieved. The processing of the thread bundle brought together after the draw-off into threads running in parallel may be alternatively or in combination a drafting, tangling, thermal treatment or doubling. Preferably, the threads are drafted in various ways before being wound up, so that, as processing member, the draw-off member is preferably followed by a driven drafting galette, for example for the production of POY yarns, or by at least one driven galette duo for drafting the threads. However, the processing member can also be formed solely by a tangling apparatus which contains a plurality of thread processing ducts with a processing distance of high packing density particularly in the case of preceding or following guides by galettes. Preferably, the tangling apparatus precedes the drafting galette in the thread run, so that a thread tension beneficial for winding up the threads can be set and can be selected. Moreover, arranging the tangling apparatus upstream of the drafting galettes in the thread run has the advantage that, in the case of singly or multiply looped drafting galettes, the projecting lengths remain relatively low on account of the small thread distances. Furthermore, to produce microfilaments with high uniformity of physical properties, a cooling apparatus is proposed which has a blow cartridge per spinneret. In this case, a cooling airstream directed radially from the inside outward for cooling the annularly guided filament bundle of one of the spinnerets is generated in each case by the blow cartridges. In this case, the filament bundle can be guided both into one thread or even into several threads. To form several threads from a filament bundle, a preparation apparatus is preferably used, which has a plurality of preparation thread guides per spinneret. The annular filament bundle can consequently be converted into several threads. Some exemplary embodiments of the device according to the invention and also the method according to the invention are described in more detail below with reference to figures 1 to 3 in which: fig. 1 shows diagrammatically a first exemplary embodiment of the device according to the invention for carrying out the method according to the invention, fig. 2 shows diagrammatically a second exemplary embodiment of the device according to the invention, fig. 3 shows diagrammatically a further exemplary embodiment of the device according to the invention. Fig. 1 shows diagrammatically a first exemplary embodiment of a device according to the invention for melt-spinning, drawing off, processing and winding up several synthetic threads. The device has, for the production of several threads, a spinning apparatus 1, a cooling apparatus 2 following the spinning apparatus 1 and a winding-up apparatus 3 provided for winding up the threads. The spinning apparatus 1 has a plurality of spinnerets 8.1 to 8.6 arranged next to one another in parallel. The spinnerets 8.1 to 8.6 are held on the underside of a heatable spinning beam 7. The spinning beam 7 contains a plurality of spinning pumps and melt distributors, not illustrated here, which are connected to a melt source, for example an extruder, via a melt inflow 12. The spinnerets 8.1 to 8.6 have on their underside an annular arrangement of a multiplicity of spinneret bores through which a multiplicity of filaments can be extruded. Below the spinning apparatus 1 is provided a cooling apparatus 2 which is formed by a plurality of blow cartridges 1(K 1 to 10.6 within a cooling well 34. The blow cartridges 10.1 to 10.6 are assigned centrally to the spinnerets 8.1 to 8.6, the filaments extruded through the spinnerets 8.1 to 8.6 surrounding the respectively assigned blow cartridges 10.1 to 10.6 in jacket form as an annularly guided filament bundle. The undersides of the blow cartridges 10.1 to 10.6 are connected to a cooling air source. Directly below the cooling apparatus 2 is provided a preparation apparatus 4 which has a plurality of preparation thread guides 11.1 to 11.6 assigned to the spinnerets 8.1 to 8.6. Below the preparation apparatus 4 are provided two draw-off members 5.1 and 5.2 arranged at a distance from one another. The draw-off member 5.1 is in this case formed by a first galette 13.1 which is assigned in the vertical direction to the spinnerets 8.1, 8.2 and 8.3, in order to draw off a first group of threads 35.1 from the spinning apparatus 1. The second draw-off member 5.2 is formed by a second galette 13.2 which is assigned in the vertical direction to the spinnerets 8.4, 8.5 and 8.6 # in order to draw off a second group of threads 35.2 from the spinning apparatus 1. The galettes 13.1 and 13.2 are driven via the galette drives 14.1 and 14.2. A group converter 15 is provided for controlling the galette drives 14.1 and 14.2. The draw-off member 5.1 is preceded by a first thread deflection rod 16.1, a collective thread guide 17.1 and a pretangling apparatus 18.1. The second draw-off member 5.2 is assigned a second thread deflection rod 16.2, a collective thread guide 17.2 and a pretangling apparatus 18.2. Laterally next to the draw-off members 5.1 and 5.2 is provided a processing member 6 which is formed by a main tangling apparatus 21 and a drafting galette 19. In this case, the main tangling apparatus 21 directly precedes the drafting galette 19 in the thread run. For the run-off of the threads guided with partial looping on the drafting galette 19, a run-off thread guide 22 is provided, by means of which the threads are kept at a processing distance when they run off from the drafting galette 19. The drafting galette 19 is driven by a galette drive 14.3 . Below the processing member 6 is arranged the winding-up apparatus 3, The winding-up apparatus 3 has, in the thread run direction, a traversing apparatus 24, a pressure roller 25 and a first bobbin spindle 26.1. The threads are wound into bobbins 27 on the bobbin spindle 26.1. The bobbin spindle 26.1 is held on a turntable 28 which carries, offset at 180° to the bobbin spindle 26.1, a second bobbin spindle 26.2. For thread guidance, the traversing apparatus 24 is preceded in each case, per thread, by a head thread guide 23. The device illustrated in fig. 1 is particularly suitable for producing what are known as POY threads. For this purpose, a predetermined polymer melt is extruded at each of the spinnerets 8.1 to 8.6 in each case into a filament bundle 9.1 to 9.6. Each of the filament bundles 9,1 to 9.6 is cooled by a cooling medium stream directed radially from the inside outward through the blow cartridges 10.1 to 10.6 and, after cooling, is consolidated into a thread in each case by means of a preparation thread guide 11.1 to 11.6. The threads extruded through the spinnerets 8.1 to 8.3 constitute a first group of threads 35.1 which are drawn off from the spinning apparatus 1 by the draw-off member 5.1. The spinnerets 8.4 to 8.6 form a second group of threads 3 5.2 which are drawn off from the spinning apparatus by the second draw-off member 5.2. In this case, the threads of the two groups 35.1 and 35.2 are guided in a common spinning plane during the consolidation of the filament bundles. By contrast, the thread bundle 36 formed by all the threads is guided in the processing member 6 into a processing plane which is oriented essentially orthogonally to the spinning plane. For this purpose, it is necessary that the threads are rotated through approximately 90° from the transition out of the spinning apparatus 1 or the preparation apparatus 4 into the processing member 6. In order to guide the threads of the first group 35.1 out of the spinning plane, the first draw-off member 5.1 is preceded by a thread deflection rod 16,1 and the collective thread guide 17.1. By means of the collective thread guide 17.1, the threads of the first group 35.1 are reduced from spacing distance defined by the distance between adjacent spinnerets 8.1 and 8.2 into a guide distance. The guide distance between the threads remains essentially constant from the collective thread guides 17.1 as far as the processing member 6. Before the threads run from the collective thread guide 17.1 onto the first galette 13.1, a swirling of the individual threads takes place in the pretangling apparatus 18.1. Such a pretangling apparatus is known, for example, from DE 100 23 910 Al, and therefore reference may be made to the cited publication at this juncture. In order to lead the second group of threads 35,2 out of the spinning plane, the second thread deflection rod 16.1 and the second collective thread guide 17.2 are provided. In this case, the threads of the second group 35.1 are likewise reduced from the spacing distance into a guide distance by the collective thread guide 17.2 To draw off the two groups of threads 35.1 and 35.2, the galettes 13.1 and 13.2 are driven at identical circumferential speeds. For this purpose, the galette drives 14.1 and 14,2 are activated by a group converter 15. The threads of the two groups 35.1 and 35.2 are drawn off from the draw-of f members 5.1 and 5.2 by the following processing member 6. For this purpose, the drafting galette 19 is driven at a circumferential speed which is preferably somewhat higher than the circumferential speed of the galettes 13 .1 and ^13.2. The threads of the first group 35.1, after partly looping around the galette 13.1, are in this case guided directly to the processing member 6. The second group of threads 35.2, after partially looping around the second galette 13.2 and after partially looping around the first galette 13.1, is guided to the processing member 6, so that, after the run-off from the first galette 13.1, the threads of the first group 35.1 and of the second group 35.2 form a common thread bundle 36. The looping angles of the threads of the second group 35.2 on the galette 13.2 and 13.1 are identical to the looping angle of the first group of threads 35.1 on the galette 13.1. Thus, all the threads, when they run into the thread bundle 3 6, are guided with identical looping angles. The threads of the thread bundle 36 are first swirled next to one another in parallel in the main tangling apparatus 21. For this purpose, the main tangling apparatus 21 has a plurality of thread processing ducts which run in parallel and in which a supply of compressed air leads to the swirling of the threads. The threads are in this case guided at a processing distance which preferably amounts to In the winding-up apparatus 3, the threads of the thread bundle 36 are wound next to one another in parallel in each case into a bobbin 27. For this purpose, the winding-up apparatus 3 has six bobbin stations lying next to one another, each of the threads being guided to a bobbin 27 via a head thread guide 23, the traversing apparatus 24 and the pressure roller 25. The apparatus, illustrated in fig. 1, for melt -spinning, drawing off, processing and winding up several synthetic threads is distinguished by an extremely compact type of construction with a low overall height. By a plurality of draw-off members being used, the zone between the points of convergence of the filament bundles, which are defined by the individual preparation thread guides 11.1 to 11.6, and the positions of the collective thread guides 17.1 and 17.2 can be reduced to a minimum, without obtaining inadmissible deflections of the thread. In spite of the division of the threads into a plurality of groups for draw-off, an advantageous processing of the threads as a thread bundle is maintained. Consequently, for processing, guide distances between the threads can be achieved which allow a compact type of construction of individual assemblies. Guide distances in the range of Fig. 2 illustrates a further exemplary embodiment of the device according to the invention for carrying out the method according to the invention. The set-up and functioning of the exemplary embodiment are essentially identical to the exemplary embodiment described above according to fig. 1, and therefore reference is made to the preceding description and only the differences are explained at this juncture. In the exemplary embodiment illustrated in fig. 2, the preparation apparatus 4 has a plurality of preparation thread guides assigned to the individual spinnerets 8.1 to 8.6. Each of the spinnerets 8.1 to 8.6 is assigned two preparation thread guides 11.1 and 11.2 arranged at a distance from one another, so that a filament bundle extruded through one of the spinnerets 8.1 to 8.6 is guided into two threads running in parallel. Thus, the first group of threads 35.1 is formed by a total of 6 threads which arise from the filament bundles 9.1, 9.2 and 9.3 of the spinnerets 8.1, 8.2 and 8.3. The second group of threads 35.2 is likewise formed by six threads which arise from the filament bundles 9.4, 9.5 and 9.6 of the spinnerets 8.4, 8.5 and 8.6. The two groups of threads 35.1 and 35.2 are drawn off by the draw-off members 5.1 and 5.2. In this case, the groups of threads 35.1 and 35.2 are guided in each case by a thread deflection rod 16.1 and 16.2 and a collective thread guide 17.1 and 17.2 out of the spinning plane into a processing plane which is oriented orthogonally to the spinning plane. In this case, the threads of the two groups 35.1 and 35.2 are brought together in each case into a part thread bundle, with a guide distance between the individual threads. The galettes 13.1 and 13.2 of the draw-off members 5.1 and 5.2 and the drafting galette 19 of the processing member 6 are arranged next to one another in a thread run plane, the axial orientation of the galettes 13.1, 13.2 and 19 lying parallel to the processing plane. This affords an advantageous thread run which leads to a particularly compact type of construction of the device according to the invention. The galettes 13.1 and 13.2 are preceded in each case in the processing plane by a pretangling apparatus 18.1 and 18.2. For a further explanation of the thread run and of the thread processing, reference may be made at this juncture to the abovementioned exemplary embodiment according to fig. 1. The exemplary embodiments according to fig. 1 and 2 are particularly suitable for producing textile POY threads. However, the device according to the invention and the method according to the invention are not restricted to the production of specific yarn types. Thus, by virtue of any desired configuration of the draw-off members and the treatment members, the device according to the invention and the method according to the invention can be employed for the production of all commonly available textile threads (POY, FDY, HOY) , industrial threads and BCF threads. By a plurality of draw-off members being used for the simultaneous draw-off of a plurality of groups of threads from a spinning apparatus, particularly low overall heights of the spinning plant can be achieved. The number of spinnerets arranged next to one another in the exemplary embodiments shown is exemplary and could 1 ikewi se be formed by eight, ten, twelve or even more spinnerets. Fig. 3 illustrates a further exemplary embodiment of a device which can be used for the production of fully drafted threads. In order to avoid repetition, only the differences from the abovementioned exemplary embodiments are explained in the following descriptions. The spinning apparatus 1 has on a spinning beam 7 a total of eight spinnerets 8.1 to 8.8 arranged next to one another. Each of the spinnerets 8.1 to 8.8 contains on its underside a circular arrangement of spinneret bores through which a multiplicity of filaments can be extruded. Below the spinning apparatus 1 is arranged a cooling apparatus 2 with a cooling well 34 and with crossflow blowing, not illustrated here. In this case, a cooling medium stream directed from outside transversely onto the filament bundles is generated for cooling the filaments. The preparation apparatus 4 provided below the cooling apparatus 2 contains in each case a preparation thread guide 11.1 to 11.8 for each of the spinnerets 8.1 to 8.8, in order to bring together the filament bundles 9.1 to 9.8 in each case into a thread. Below the preparation apparatus 4 are arranged two draw-off members 5.1 and 5.2 which are formed in each case by a driven galette 13.1 and 13.2 and in each case freely rotatable overrun rollers 29.1 and 29.2 assigned to the galettes 13.1 and 13.2. The galettes 13.1 and 13.2 are preceded in each case by a collective thread guide 17.1 and 17.2 and a pretangling apparatus 18.1 and 18.2. The threads are divided into two groups 35.1 and 35.2 by means of the collective thread guides 17.1 and 17.2 and are drawn off from the spinning apparatus 1 via the assigned draw-off members 5.1 and 5.2. The arrangement of the collective thread guides 17.1 and 17.2 is in this case symmetrical to the assigned spinnerets 8.1 to 8.4 and 8.5 to 8.8. A uniform deflection of the, in particular, outer threads is consequently achieved. To draw off the threads of the two groups 35.1 and 35.2, the galette drives 14.1 and 14.2 are activated at an identical frequency by a group converter 15, so that both galettes 13.1 and 13.2 rotate at identical circumferential speeds. In this case, the galettes 13.1 and 13.2 and the assigned overrun rollers 29.1 and 29.2 are looped multiply by the threads. A run-off thread guide 32.1 and 32.2 is assigned in each case on the run-off side of the draw-off members 5.1 and 5.2, in order to maintain between the threads a guide distance which is set during the draw-off. The threads of the two groups 35.1 and 3 5.2 are brought together into a thread bundle 36 by the run-off thread guide 22.1 and 22.2. For this purpose, the thread bundle 36 is guided via the collective thread guide 33 which precedes a processing member 6. The processing member 6 is in this case formed by a drafting zone having in each case two drafting galette duos 31.1 and 31.2. Each of the drafting galette duos 31.1 and 31.2 is driven in each case via a drive unit 37.1 and 37.2 consisting in each case of an electric motor with converter. The drive units 37.1 and 37.2 are connected to a control unit 3 0 which is likewise connected to the group converter 15 of the draw-off members 5.1 and 5.2. In the processing member 6, the threads are guided and drafted next to one another in parallel via the drafting galette duos 31.1 and 31.2. For this purpose, a speed difference is set between the drafting galette duos 31.1 and 31.2. The drafting galette duos 31.1 and 31.2 are formed in each case on two galettes which are arranged in a plane perpendicular to the drawing plane. In fig. 3, therefore, only one of the galettes is illustrated. After drafting, the threads of the thread bundle 36 are drawn off by the winding-up apparatus 3 and wound up into bobbins 27. For thread guidance, here, the last drafting galette duo 31.2 is assigned a run-off thread guide 22, by means of which the threads acquire within processing member 6 a predetermined processing distance from one another. The threads of the thread bundle 36 are subsequently spread apart and supplied to the winding-up apparatus via the individual head thread guides 23. The winding-up apparatus 3 is designed identically to the preceding exemplary embodiments, so that, on a bobbin spindle 26.1 of great projecting length, a total of 8 threads are simultaneously wound into bobbins 27. The exemplary embodiment, illustrated in fig. 3, of the device according to the invention for carrying out the method according to the invention is based on the fact that the threads are guided in one thread plane between spinning and winding up. The spinning plane and the processing plane lie parallel to one another, so that the winding-up apparatus 3 is oriented parallel to the spinneret row of the spinning apparatus 1. This exemplary embodiment is particularly suitable for the production of FDY threads.

The device as claimed in claim 8, characterized in that the galette drives (14.1, 14.2) of the galettes (13.1, 13.2) can be controlled by means of a group converter (15). 10. The device as claimed in claim 8 or 9, characterized in that the galettes (13.1, 13.2) are assigned in each case an overrun roller (29.1, 29.2) around which the threads are multiply looped. 11. The device as claimed in one of claims 1 to 10, characterized in that the processing member (6) is formed by a driven drafting galette (19) or by a driven galette duo (31.1). 12. The device as claimed in one of claims 1 to 11, characterized in that the processing member (6) has a tangling apparatus (21) which contains a plurality of thread processing ducts with a processing distance of less than 10 mm. 13. The device as claimed in claim 12, characterized in that the tangling apparatus (21) precedes the drafting galette (19) in the thread run. 14. The device as claimed in one of the claims, characterized in that the cooling apparatus (2) has per spinneret (8.1 ... 8.6) a blow cartridge (10.1 ... 10.6) which in each case generates a cooling airstream directed radially from the inside outward for cooling the annularly guided filament bundle (9.1 ... 9.6) of one of the spinnerets (8.1 ... 8.6). 15. The device as claimed in claim 14, characterized in that the cooling apparatus (2) is assigned a preparation apparatus (4) which has a plurality of preparation thread guides (11.1 ... 11.12) per spinneret (8.1 ... 8.8), the filament bundle (9.1 ... 9.6) of the assigned spinneret (8.1 ... 8.6) being converted into a plurality of threads by the preparation thread guides (11.1 ... 11.12) . 16. A method for melt-spinning, drawing-off, processing and winding up several synthetic threads in the following steps: 16.1. Extrusion and cooling of a plurality of filament bundles next to one another in parallel and bringing together of each of the filament bundles in each case into one of the threads; 16.2. Division of the threads into at least two groups of threads and draw-off of each group of threads by separate draw-off members; 16.3. The bringing together of the thread groups into a thread bundle with threads running in parallel and reception of the thread bundle for processing by a processing member, and 16.4. Winding up of the threads of the thread bundle into bobbins. 17. The method as claimed in claim 16, characterized in that the groups of threads are formed by means of a symmetrical division and deflection of the threads. 18. The method as claimed in claim 16 or 17, characterized in that the threads are guided for spinning in a first thread run plane (spinning plane), and in that the threads are guided for processing in a second common thread run plane (processing plane) rotated through 90°. 19. The method as claimed in one of claims 16 to 18, characterized in that the threads, at the transition from the spinning plane to the processing plane, are guided with essentially identical thread loopings onto the draw-off member. 20. The method as claimed in one of claims 16 to 19, characterized in that the draw-off members are operated synchronously for drawing off the threads.
