In order to improve the application process regarding the distribution of the filaments on the individual winding points when starting the process or pausing the process, the take-off godet and the group of the top thread guides for applying the threads into the winding points of the winding machine are designed to be moveable relative to each other according to the invention.

Description

Device for melt spinning and winding synthetic threads

The invention relates to a device for melt spinning and winding synthetic threads according to the preamble of claim 1.

A generic device for melt spinning and winding of synthetic threads is known from WO 2004/015173 Al.

In the known device, the synthetic threads are extruded parallel to each other in a spinning device from a polymer melt to a plurality of filament strands, cooled and bundled. Subsequently, the threads are guided parallel in a treatment device preferably via godet systems, to be wound in the end in a winding machine parallel to coils. The threads are guided from melt spinning to winding with different thread pitches and different levels. Thus, the threads are guided in parallel in the treatment device with a relatively close thread spacing. In the winding machine, however, the threads must be brought to a winding spacing, which is essentially due to the coil width of the coils of the individual winding units. The group of threads is thus spread apart from the treatment distance to the winding spacing.

In order to obtain the most compact arrangement, the threads are guided immediately after expiry of a Ablaufgalette in the winding units of the winding machine, wherein the yarn guide between the winding units and the Ablaufgalette each a head thread guide is arranged. For this purpose, the sequence godet is arranged transversely to the winding stations in a front end region of the winding machine, so that the threads can be distributed to the individual winding stations in the short distance between the running godet and the winding machine. Here is the A yarn sheet from a certain by the Ablaufgalette management level überfuhrt in a traversing plane, which is aligned substantially orthogonal to the godet axis of the Ablaufgalette. Such a yarn transition requires a particular skill of the operator when first applying the threads, in which the group of threads are usually performed by an operator with the help of a suction gun.

Although auxiliary devices for distributing the threads in winding stations of a winding machine, for example from DE 198 27 635 A1, are known in the prior art, in which movable thread guides are guided between a threading position and a transfer position. The guide level of the thread guide is in this case parallel or identical to the traversing plane, so that the threads for threading into the thread guide in the threading position preferably also in this plane must be supplied. In that regard, the known auxiliary devices for the generic device can not be used.

It is therefore an object of the invention to improve the device of the generic type such that the application of the threads can be carried out safely and reproducibly, especially in the transition region between the treatment device and the winding machine.

Another object of the invention is to make the application process of the yarn sheet in the generic device as possible without borrowed funds.

This object is achieved by a device with the features of claim 1.

Advantageous developments of the invention are defined by the features and feature combinations of the subclaims. The invention advantageously uses the structural arrangement of the transverse godet directed transversely to the winding stations in order to guide the threads one after the other directly into the head thread guides. For this purpose, the sequence godet and the group of head thread guides are designed to be movable relative to one another, so that an automatic application of the threads into the head thread guides is achieved solely by the re-motive movement between the sequence godet and the head thread guides. For example, very short interruption times can be achieved in the event of a yarn breakage and a new creation of the yarn sheet. In addition, forced guides of the threads are possible, which facilitates the creation of the threads substantially independent of an operator.

In a particularly advantageous embodiment of the device according to the invention the Ablaufgalette is arranged on a movable godet carrier, which is guided on a guide rail, which extends from a front end region of the winding machine to an opposite end region of the winding machine. Here, the group of threads through the Ablaufgalette can lead along the winding units, being passed to each winding unit of the head thread guide associated thread. Thus, the threads during the movement of the Ablaufgalette can be successively transferred from a front end region of the winding machine to an opposite front end region of the winding machine in the head thread guide.

In order to reach the operating state as quickly as possible after completion of the movement of the flow godet, the godet carrier holds the flow godet on one of the front end regions of the winding machine in an operating position. The at the opposite end region of the winding machine is defined a landing position of the Ablaufgalette, in which the threads are applied to the periphery of the Ablaufgalette. The application of the threads to the Ablaufgalette can also be initiated by the movement of the godet carrier, so that when passing the Ablaufgalette of the landing position in the operating position an automatic application of the threads to both the Ablaufgalette and the head thread guide is executable.

In order that the individual yarns assigned to the head thread guides can be handed over safely during the movement of the sequence godet, according to an advantageous development of the invention, the guide rail of the fork carrier is arranged obliquely above the winding machine such that the threads guided on the circumference of the sequence godet in the laying position and the thread guide associated with the threads lie in each case in a common management plane. Thus, upon movement of the process godet, each of the yarns is automatically guided into the head yarn guide without any further deflection or deflection.

In the event that the treatment device can be equipped only with stationary godet systems, the development of the invention is preferably used, in which the group of head thread guides is arranged on a movable yarn guide carrier and that the yarn guide carrier is guided in a slide, which towards a front end region of the winding machine below the Ablaufgalette extends. In this case, the mobility of the head thread guides is used to take over the running of the Ablaufgalette threads and to lead them into their respective winding unit.

According to a particularly advantageous device variant of the thread guide carrier is held with the group of head thread guide in an operating position above the winding units and a catch position on the front end of the Aufspulmaschi- ne, the guided at the periphery of the Ablaufgalette threads when passing from the catch position to the operating position individually from the Head thread guides are accepted. Thus, the head thread guides can lead directly after taking over the respectively associated threads the traversing planes, in which the thread of the winding unit is supplied.

- A - In order to be able to take over the threads routed side by side by the sequence godet directly by the head thread guides and to guide the head thread guides with the threads directly into the traversing plane, according to a preferred development of the invention the slide rail of the thread guide carrier is so inclined to the winding stations aligned that the head thread guides span the transition from the operating position to the catch position with the threads assigned to them at the periphery of the Ablaufgaletten a common management level. Thus, a positive guidance in the acquisition and positioning of the threads is achieved, which makes an intervention of an operator unnecessary. This makes it even possible to implement automated application processes in the device.

Alternatively, however, there is also the possibility that the head thread guides are arranged according to an advantageous development of the invention on the thread guide carrier offset from each other projecting that when passing from the catch position to the operating position of the head thread guide with their associated threads on the circumference of the Ablaufgalette a common management level spans, wherein the yarn guide carrier is pivotally held in the operating position for aligning the head thread guide in the traversing plane.

In order to safely create a plurality of threads in a compact arrangement of the treatment device and the winding machine, the development of the device according to the invention can be used particularly advantageously, in which the Ablaufgalette is associated with a guide means for guiding the plurality of parallel threads through which between the threads a thread spacing in the range of 2 mm to 8 mm is determined. Such thread spacings can still be mastered between the threads in the case of automated forced operation without the result of unwanted entrainment of several threads by the head thread guides. This thread spacing, determined by the guide means, at the same time provides for the treatment of the threads in the treatment device. In this way, in particular in godet systems, short overall lengths and compact designs can be realized.

In this case, a plurality of row-shaped yarn guides of the sequence godet arranged next to one another can be arranged downstream of the yarn path in the yarn path as guide means, which yarns are formed, for example, by ceramic pins or comb-shaped ceramic guides. However, it is also possible to form the guide means directly by a plurality of radial guide grooves on the circumference of the Ablaufgalette. Thus, the threads are guided directly on the circumference of the godet in the guide grooves even with the relative movements between the Ablaufgalette and the head thread guides.

In order to minimize the yarn friction, which must not exceed impermissible maximum values, especially in the application process, is provided according to a preferred variant of the invention to form the head thread guides in the winding machine by each freely rotatable guide rollers whose roller axes are aligned substantially orthogonal to a winding spindle of the winding machine , This also makes it possible to carry out relatively large thread deflections with low friction, so that a spacing between the discharge galette and the head thread guides chosen for the distribution of the threads can be set low.

In order to obtain a secure guidance of the tapered threads in the guide rollers with substantially smooth Führungsma¬teln, the formation of the device according to the invention is particularly advantageous in which the roller axis of the guide rollers depending on the respective deflection angle of the associated thread have a tendency relative to the axis of the Ablaufgalette. This makes it possible to run the threads substantially at right angles to the guide rollers. However, the guidance of the threads can also be improved in that the guide rollers each have on the circumference a groove-shaped guide track in which the tapered thread is guided.

The device according to the invention is explained in more detail below with reference to some embodiments with reference to the attached figures.

1, 2 and 3, a first embodiment of the inventive device is shown in several views. In Fig. 1, the device is shown in a side view, in Fig. 2 in a front view and in Fig. 3 in a section of a plan view. The following description applies, insofar as no explicit reference is made to one of the figures, for all figures.

The device according to the invention is composed of a spinning device 19, a treatment device 26 and a winding machine 27, wherein a Plural of synthetic threads are made side by side in parallel. For this purpose, a plurality of spinnerets 22.1 to 22.4 are held in the spinning device 19 on an underside of a heated spinneret 20, which are connected via a melt feed 21 to a melt source, for example an extruder (not shown here). In the embodiment, a total of four spinnerets 22.1 to 22.4 arranged in rows next to each other. The number of spinnerets is exemplary, so fewer or more threads can be spun simultaneously by means of a spinning device. Each of the spinnerets 22.1 to 22.4 has a plurality of nozzle bores for extruding a filament bundle of a multifilament yarn from a polymer melt supplied via the melt feed 21. Before the individually extruded filament strands of the filament bundle are brought together to form the respective threads 2.1 to 2.4, the filament bundles pass through a cooling shaft 23 arranged below the spinning beam 20. The cooling shaft 23 is combined with a blast 24, so that within the cooling shaft 23 a cooling air flow onto the filament bundles acts. The cooling air flow can - as shown - be generated by a cross-flow blowing. However, it is also possible to generate the cooling air flow through a cooling cylinder with a Umumanblasung from outside to inside or from the inside out.

In the outlet region of the cooling shaft 23, a preparation device 31 and a plurality of collecting thread guides 32 are arranged in order to combine the filament bundles to the respective threads 2.1 to 2.4. A chute 25 immediately adjoins the cooling shaft 23 in order to guide the threads 2.1 to 2.4 to the treatment device 26.

Below the chute 25, a yarn guide strip 33 and a Fadensamme lvorrichtung 29 is arranged, wherein the yarn guide strip 33 to each of the threads 2.1 to 2.4 forms a yarn guide through which a treatment distance is set between each of the threads 2.1 to 2.4. The threads 2.1 to 2.4 are guided over the collection thread guide 32 from the spinning division out on the yarn guide strip 33 to the treatment distance.

The yarn guide strip 33 is associated with the yarn collecting device 29, through which the yarn sheet can be merged at yarn breakage and removed via a suction. The yarn collecting device 29 has a movable guide means and a suction to collect the threads 2.1 to 2.4 at thread break can. Such devices are well known and described for example in EP 1 049 823 Bl.

The treatment device 26 comprises at least one sequence godet 14, which is arranged directly upstream of the winding machine 27. The sequence godet 14 is assigned to a front end region 40 of the winding machine 27. The spinning device 19 and the Ablaufgalette 14 are arranged transversely directed to a longitudinal axis of the winding machine 27. Such a device is known from EP 1 527 217, so that its contents are hereby expressly incorporated by reference.

In addition to the expiration godet 14, the treatment device 26 has a pre-arranged second godet, which in this example is designated as a withdrawal godet 28. The withdrawal godet 28 pulls the threads 2.1 to 2.4 from the spinning device 19. The godet godet 28 and the godet 14, which in this case acts as a draw galette, are each driven by a godet drive 34. In this case, the peripheral speeds of the withdrawal godet 28 and the discharge lane 14 can be set with a difference, depending on the process and thread type. The threads 2.1 to 2.4 are guided in an S-shaped threadline with the predetermined thread treatment distance between the threads parallel over the circumference of the Abzugsgalette 28 and the Ablaufgalette 14. In the yarn path between the Abzugsgalette 28 and the Ablaufgalette 14 a swirler 30 is arranged to swirl each thread individually. This creates a thread closure in the threads for further processing.

Below the treatment device 26, the winding machine 27 is arranged. The winding machine 27 has a total of four winding units 1.1 to 1.4, which are formed side by side in the winding machine 27. The winding units 1.1 to 1.4 are arranged along a winding spindle 27 held on the winding spindle 6.1. In each of the winding units 1.1 to 1.4 each one of the threads 2.1 to 2.4 is supplied and wound into a coil 8, the structure of the winding units 1.1 to 1.4 is identical, so that the basic structure is described based on the front end region 40 facing winding unit 1.1.

The winding unit 1.1 has a traversing means 4, through which a supplied thread 2.1 is guided back and forth within a traverse stroke. The traversing means 4 could for example be formed by a Kehrgewindewellenchangierung in which a traversing yarn guide within a traverse stroke and forth, or a Flügelchangierung with a plurality of oppositely driven wing tips, pulling the thread back and forth lead. The traversing means 4 is preceded by a head thread guide 3.1, which forms the tip of a so-called traversing triangle within a traversing plane. The head thread guide 3.1 thus forms the inlet into the winding unit 1.1.

To wind the thread 2.1 in the winding unit 1.1, a winding tube 9 is clamped on the circumference of a driven winding spindle 6.1. The winding spindle 6.1 extends over all adjacent winding units 1.2, 1.3 and 1.4, so that in each of the winding units 1.1 to 1.4, the supplied yarns 2.1 to 2.4 are wound simultaneously.

To store the thread 2.1 on the surface of the spool 8 in the winding unit 1.1 is a pressure roller 5 between the traversing means 4 and the winding spindle 6.1 arranged. The pressure roller 5 also extends over the entire length of the winding units 1.1 to 1.4. The thread 2.1 is stored after Teilumschlingung on the circumference of the pressure roller 5 on the surface of the coil 8.

A machine frame 10 serves to receive and fix the traversing means 4, the pressure roller 5 and the winding spindle 6.1. In this embodiment, the pressure roller 5 is held by a rocker 13 pivotally mounted on the machine frame 10. The winding spindle 6.1 is cantilevered in a winding turret 7, which is rotatably held in the machine frame 10. The winding volver 7 holds by 180 ° offset from the winding spindle 6.1 a second winding spindle 6.2 in order to be able to carry out a continuous winding of the threads in the winding stations 1.1 to 1.4. The winding turret and the winding spindles 6.1 to 6.2 each drives (not shown here) are assigned. The head thread guides 3.1 to 3.4 in the winding units 1.1 to 1.4 are each formed by freely rotatably mounted guide rollers 11.1 to 11.4. The guide rollers 11.1 to 11.4 are aligned at the winding units 1.1 to 1.4 respectively with their roller axes orthogonal to the winding spindle 6.1. The guide rollers 11.1 to 11.4 have at their periphery in each case a circumferential Fadenführungsnut 46, in which the thread is guided with Teilumschlingung. The guide rollers 11.1 to 11.4 are preferably mounted by an air bearing the roller axes. The guide rollers 11.1 to 11.4 are held on a movable yarn guide carrier 12, which is guided in a slide rail 15. By moving the yarn guide carrier 12 in the slide rail 15, the head thread guides 3.1 to 3.4 together as a group above the winding units 1.1 to 1.4 lead from an operating position to a catch position in the front end region 40 of the winding machine 27. In Figs. 1 to 3, the operating position of the head thread guide 3.1 to 3.4 is shown. The catch position of the head thread guide 3.1 to 3.4 is shown in dashed lines in FIGS. 1 and FIG.

In the operating position, the head thread guides 3.1 to 3.4 are held together by the thread guide carrier 12 all together in the traversing plane 36. The traversing Level 36 is indicated in Fig. 3 by a dashed line. For the first application of the threads 2.1 to 2.4 in the winding units 11.1 to 11.4, the threads must be passed after the expiration of the Ablaufgalette 14 to the head thread guides 3.1 to 3.4. For this purpose, the yarn guide carrier 12 is guided in the slide rail 15 to the front face end region 40 of the winding machine 27 until the head thread guides 3.1 to 3.4 have reached the catch position shown dashed in FIGS. 1 and 3. The slide rail 15 is aligned obliquely to the coil points 1.1 to 1.4, that sets an acute angle α between the traversing plane 36 and the slide rail 15. As can be seen in particular from FIG. 3, in this exemplary embodiment the yarn guide carrier 12 is formed by a holder 18 which is supported on the slide rail 15 by means of a sliding shoe 16 over a plurality of struts 17 of different lengths. Thus, held on the holder 18 head thread guide 3.1 to 3.4 can be held in relation to the inclined slide rail 15 together in the operating position in the traversing plane 36.

The yarn guide carrier 12, which is preferably moved by manual guidance of a handle 44 along the slide rail 15, leads each of the head thread guides 3.1 to 3.4 depending on the angle α on a separate management level, each between the head thread guides 3.1 to 3.4 and from the Ablaufgalette 14 expiring threads 2.1 to 2.4 spans. In Fig. 3, the guide planes are shown in dashed lines and identified by the reference numerals 35.1 to 35.4.

To guide the yarn guide support 12, the slide rail 15 preferably extends over the front end region 46 of the winding machine 27. For catching and taking over the threads 2.1 and 2.4, the yarn guide carrier 12 is moved from the catching position into the operating position of the head thread guide 3.1 to 3.4 formed above the winding machine guided. As the movement progresses, the thread 2.4 is first caught by the head thread guide 3.4 and guided in the direction of the operating position. Subsequently, the acquisition of the thread 2.3 with the head thread guide 3.3 and subsequently the thread 3 by the head thread guide 3.2 and finally the thread 2.1 through the head thread guide 3.1. The threads 2.1 to 2.4 are thus detected automatically with progressive movement of the yarn guide carrier 12 by the head thread guides 3.1 to 3.4 and guided into the operating position. Subsequently, the threads can be guided by not shown here auxiliary equipment within the winding machine to the sleeves and their catch, so that the process can be started.

In order to obtain a clear assignment as possible when catching the threads 2.1 to 2.4 by the head thread guides 3.1 to 3.4, the thread spacings of the threads 2.1 to 2.4 at the periphery of the Ablaufgalette 14 by guide grooves 39 are determined. For each thread 2.1 to 2.4, the Ablaufgalette 14 on its circumference in each case a circumferential guide groove 39. In that regard, as shown in Fig. 1, the yarn sheet is guided by a suction gun 43 during the application process. The application situation and the suction gun 43 are shown dashed in FIG. 1 for this purpose. By positioning the suction gun 43 below the Ablaufgalette 14 can thus be adjusted in the amount of head thread guides 3.1 to 3.4 in vorgeefmierten thread intervals between the threads 2.1 to 2.4, which allow a proper acquisition of guided in the individual management levels 35.1 to 35.4 head thread guide 3.1 to 3.4 , Usually, the thread pitches are selected on the circumference of the Ablaufgalette in a range of 2 mm to 8 mm. This allows even larger amounts of thread without mutual interference safely lead in the treatment device 26 and treat. Likewise, thus relatively small angular positions of the slide rail 15 in relation to the traversing plane 36 can be realized.

The device shown in FIGS. 1 to 2 is particularly suitable for producing pre-oriented threads into so-called POY yarns. By running essentially without thread guide elements distribution of the threads from the treatment device 26 to the winding machine 27, the threads can be wound up with low thread tensions and lead. By forming the head thread guide as guide rollers even the required deflection of Threaded during the application process and during operation very low friction. Thus, the device is suitable both for very fine denier and for coarse yarn titer. However, it should be expressly stated at this point that the device according to the invention, depending on the configuration of the treatment device 34, is also suitable for the production of fully drawn FDY yarns or other types of yarn.

4, a further embodiment of the device according to the invention is shown in a section of a plan view. The exemplary embodiment is identical to the exemplary embodiment according to FIGS. 1 and 2, so that in the illustration in FIG. 4 only the sequence godet 14 and the head thread guides 3.1 to 3.4 arranged underneath are shown. In this case, in particular, the attachment and guidance of the head thread guide 3.1 to 3.4 executed differently in comparison with previous embodiments and described below.

The head thread guides 3.1 to 3.4 are also formed in this embodiment by freely rotatable guide rollers 11.1 to 11.4, which are mounted in each case a roller axle 47.1 to 47.4. The roller axles are attached at their opposite ends to a yarn guide carrier 12. For this purpose, the roller axes 47.1 to 47.4 are designed differently in their length, so that the guide rollers 11.1 to 11.4 are arranged offset from one another at different distances from the yarn guide carrier 12. The offset set between the head thread guides 3.1 to 3.4 is marked with the capital letter B. The offset B is here preferably carried out identically between the adjacent head thread guides 3.1 to 3.4 and corresponds to a thread pitch A, which adjusts at the expiration of the threads 2.1 to 2.4 of the Ablaufgalette 14.

The yarn guide carrier 12 is formed in this embodiment by a rail-shaped holder 18 which is guided in a slide rail 15 movable. The displacement of the yarn guide carrier 12 is hereby preferably carried out manually, for which purpose the holder 18 has a handle 45 at one end. The slide rail 15 is held on a pivot axis 44 and can be reciprocated between an operating position and a catching position. 4, the operating position of the slide rail 15 is shown.

In order for a process start or after a yarn break the threads 2.1 to 2.4 in the below the head thread guides 3.1 to 3.4 arranged winding points, the slide rail 15 is guided by pivoting about the pivot axis 44 in its Anlegstellung. The yarn guide carrier 12 is then moved along the slide rail 15 into its catching position so that the head thread guides reach the opposite side to the drainage roll 14. Now, the threads are applied by means of a suction gun, not shown here in the guide grooves 39 on the periphery of the Ablaufgalette 14 and continued downwards. The thread pitch that results is marked in FIG. 4 with the letter A. The threads 2.1 to 2.4 wrap around the process godet 14 on the side at which the head thread guides 3.1 to 3.4 are held in their catching position. Since the offset B, the head thread guide 3.1 to 3.4 is equal to the thread pitch A between the threads 2.1 to 2.4, stretch the head thread guides 3.1 to 3.4 with the associated threads 2.1 to 2.4 a common management level 35.1 to 35.4, so that upon movement of the yarn guide carrier 12th at the held in the landing slide 15, the threads 2.1 to 2.4 automatically slide into the thread guide grooves 46 of the guide rollers 11.1 to 11.4. After the thread guide carrier 12 has reached a stop 49 at the end of the slide rail 15, the slide rail 15 is pivoted from its landing position into the operating position in order to guide the head thread guides 3.1 to 3.4 into the traversing plane 36. Thus, the threads 2.1 to 2.4 can now be created by other auxiliary equipment not shown here in the winding units 1.1 to 1.4.

In the operating position shown in FIG. 4, the guide rollers 11.1 to 11.4 have a low tendency relative to the Ablaufgalette, so that the of

Sequential godet 14 running substantially perpendicular to the Füh- ment rollers 11.1 to 11.4 can be supplied. Thus, a particularly safe and quiet thread run is achieved during the course of the threads of the Ablaufgalette 14 in the transition region to the head thread guides.

Alternatively, the exemplary embodiment of the device according to the invention shown in FIG. 4 can also be designed such that each of the guide rollers 11.1 to 11.4 is held at an identical distance from the yarn guide carrier 12. For this purpose, each of the guide rollers 11.1 to 11.4 associated roller axes is formed with the same length. As shown in FIG. 4, the yarn guide carrier 12 is formed by a pivotable slide rail 15 and a holder 18 guided on the slide rail 15, which holder 18 holds the guide rollers 11.1 to 11.4 at a distance from one another. Compared to the embodiment of FIG. 4, the pivot axis 44 would be arranged at the free end of the yarn guide carrier 12 in this alternative arrangement. Thus, at the operating position, the yarn guide carrier 12 would be held parallel to the traversing plane 36.

At the beginning of the process, the end of the yarn guide carrier 12 associated with the godet is pivoted about the arranged at the opposite end of the yarn guide support 12 pivot axis 44 for applying the threads, the operation for applying the guided on the circumference of the godet filaments is identical to the embodiment of FIG. 4. Here, the holder 14 is guided with the guide rollers, however, on the inclined held slide rail 15.

In the exemplary embodiment illustrated in FIG. 4 and in the previously described alternative embodiment with the pivot axis at the free end of the yarn guide carrier 12, the flow godet can be arranged both orthogonal to the traversing plane (as shown in FIG. 4) or with an inclination to the traversing plane. The inclined arrangement of the Ablaufgalette opposite the traversing plane is preferably used in smooth Galettenmänteln to obtain a vertical flow of the threads from the godet shell of the Ablaufgalette. In the exemplary embodiments illustrated in FIG. 1 to FIG. 4, the thread spacing in the course of the expiration roll 14 is predetermined essentially by the guide grooves 39 introduced at the circumference of the godet. Alternatively, however, it is also possible to design the drain godet 14 without guide grooves. Thus, a variant of the embodiment shown in FIG. 4 is shown in FIG. Here, the Ablaufgalette 14 and the underlying overhead thread guide 3.1 to 3.4 are shown schematically in a front view. The process godet 14 shows a smooth guide casing without guide grooves. In the course of the threads, the threads 2.1 to 2.4 are assigned a plurality of auxiliary thread guides 42, which set a predetermined thread spacing between the threads 2.1 to 2.4. The predetermined by the auxiliary yarn guide 42 thread spacing corresponds to the amount held in the catch position head thread guides 3.1 to 3.4 the respective offset B between the held on the yarn guide carrier 12 head thread guide 3.1 to 3.4. The thread guide carrier 12 is guided in the slide rail 15, which is pivotally held on the pivot axis 44. In the situation shown in Fig. 5, the slide is in its landing position, wherein the yarn guide carrier 12 is guided in the catching position.

In the situation illustrated in FIG. 5, the threads are picked up by means of a suction pad 43 and continuously guided to a yarn waste container, not shown here. After the threads 2.1 to 2.4 are threaded into the auxiliary thread guides 42, the application process can be started. Here, as already described with reference to FIG. 4, the yarn guide carrier 12 is displaced up to a stop in the slide rail 15.

A further exemplary embodiment of the device according to the invention is shown in several views in FIGS. 6 and 7. In Fig. 6 is a side view of the embodiment and in Fig. 7 is a detail of a plan view shown schematically. The embodiment will first be described with reference to the side view shown in FIG. The structure of the spinning device 19 and the winding machine 27 is identical to the previous embodiment 1 and 2, so that reference is made to the above description and only the differences will be explained below.

The treatment device 26 provided between the spinning device 19 and the spooling machine 27 is formed by a withdrawal godet 28, which is arranged directly below a chute 25 and a subsequent discharge galette 14. The Ablaufgalette 14 is held on a movable godet carrier 37. The godet carrier 37 is slidably guided in a guide rail 38, wherein the guide rail 38 extends above the winding machine from a front end face 40 to a rear end region 41 of the winding machine 27. The godet carrier 37 can be in the guide rail 38 to guide the Ablaufgalette 14 back and forth. Here, the Ablaufgalette 14 between a docking position at the front end face 40 of the winding machine 27, which is shown in dashed lines in Fig. 6, and an operating position at the rear end portion 41 of the winding machine 27 lead. In Fig. 6, the Ablaufgalette 14 is shown in its operating position, in which the threads are continuously wound to 2.1 to 2.4 in the winding units 1.1 to 1.4, respectively to 8 coils.

To explain the application process at the beginning of a process or after interruption of a process, reference is also made to Fig. 6 in addition to FIG. 7 reference.

Below the Ablaufgalette the head thread guides 3.1 to 3.4 are held above the winding units 1.1 and 1.4 in a traversing plane. Here, the head thread guides 3.1 to 3.4 are attached to a support 48 which is fixedly connected to the machine frame 10 of the winding machine 27.

Above the head thread guide 2.1 to 2.4, the guide rail 38 is arranged inclined with the godet carrier 37, that by the guide grooves 39 of the Ablaufgalette 14 with the respectively associated head thread guides 3.1 and 3.4 each span a guide plane 35.1 to 35.4, so that by moving the godet carrier 37 in the guide rail 38, the guided in the guide grooves 39 threads 2.1 to 2.4 are successively passed to the individual head thread guides 3.1 and 3.4. The movement of the process godet 14 can also be used to first thread the yarn sheet 2.1 to 2.4 into the treatment device 26 and then to carry out further movement of the flow godet into the operating position to further distribute the yarns onto the head thread guides. The godet carrier 37 can be formed, for example, as a carriage, which is actuated in a linear drive. Thus, the Ange- gegevorgang to distribute the threads on the winding units 1.1 to 1.4 of the winding machine 27, automated executable.

The embodiments of the device according to the invention shown in FIGS. 1 to 7 are exemplary in the structure and choice of the individual components. The invention also covers similar device, which indeed differ in the construction and choice of the individual process units, but have between a last Ablaufgalette and the head thread guide a winding machine means that allows a relative movement between the Ablaufgalette and the head thread guides. Thus, the head thread guides can also be held by individual carriers which are guided by cable pull or telescopic drive means between an operating position and a catching position.
