Therefore, the yarns from the plane of symmetry can preferably be separated into individual spooling units.

Description

A device for spinning and winding a plurality of synthetic yarns {APPARATUS FOR SPINNING AND WINDING SEVERAL SYNTHETIC THREADS}

The present invention relates to an apparatus for spinning and winding up a plurality of synthetic yarns according to the preamble of claim 1.

A device of the general type is disclosed in DE 100 45 473 A1.

A method by a spinning device in which a plurality of yarns are simultaneously extruded next to each other by a spinning device and then cooled is a known method for producing melt-spun synthetic yarn. Thus, for example, twelve, sixteen, twenty, or more yarns can be produced simultaneously by a spinning device. After cooling, the yarns are guided together and treated as thread sheets. At the end of the spinning process, each yarn of the threadsheet is wound to form a bobbin. For this purpose, a plurality of spooling units are combined to form a group and assigned to the spinning device. Each spooling unit has a spooling revolver with two elongated protruding spooling spindles to enable a continuous winding process of the spun yarn. The spooling spindle can be alternately swiveled by the spooling revolver into the work area winding the yarns and the change over area removing the fully wound full bobbin.

In the case of the device disclosed in DE 100 45 473 A1, a group of spooling units consists of two spoolers arranged next to each other. In this case, the spooling units face each other in a mirror structure, and in winding the yarn, it is preferable that the winding operation is simultaneously performed in the spooling units. Therefore, the space requirement of this apparatus is substantially determined by the spooling units arranged next to each other. If the threadsheets are spun in a continuous arrangement in the spinning device, the width of the spooling unit is typically larger than the width of the spinning device, so that the partition in a large plant is determined by the winding unit. In large scale plants, however, it is desirable for a large number of spinning devices to be supplied by one extruder, so these spinning devices should be arranged as closely as possible to each other.

US 6,015,113 discloses a group of spooling units for winding a plurality of threadsheets, in which the spooling units are arranged stacked on one another in the form of tiers. Therefore, it is possible to reduce the section width of the spooling unit, but has the disadvantage that the yarn guide dominant in the upper spooling unit is different from the yarn guide dominant in the lower spooling unit. In the case of winding synthetic yarns, especially at high speeds, which may exceed 6,000 m / min, this difference in guide length in yarn guiding due to air resistance is evident as the winding tension is different, and therefore the quality is different. Bobbins and even yarns are produced.

Therefore, it is an object of the present invention, in general, to spin and wind yarns, in which the groups of spooling units are arranged in a dense configuration, on the other hand the yarns are wound on each of the spooling units under the same conditions to form bobbins. To provide a tangible device.

This object is achieved according to the invention by an apparatus for spinning and winding up a plurality of yarns, having the features according to claim 1, and also by an apparatus having the features according to claim 14.

Advantageous refinements of the invention are defined by the features and combinations of features of the respective subclaims.

The present invention is based on the fact that two spooling units embodied in mirror structures with respect to one another are stacked on each other. Therefore, on one side, it is possible to realize the partition width of the group of spooling units substantially corresponding to the partition width of one spooling unit. In addition, the narrower the spacing between the spooling spindles supported in the work area, the better the yarn feed implemented under substantially the same conditions. On the contrary, the greater the distance between the spooling spindles supported in the change-over area, it is particularly advantageous to prevent mutual interference in the guidance and removal of the full bobbin. In this case, each of the spooling units can be wound simultaneously, forming a plurality of saga bobbins.

In this case, the improvement of the invention is particularly advantageous in which the yarn guide means are arranged in the mirror-symmetric plane of the spooling units. The yarn guiding means deflects the yarns supplied from the spinning device so that the yarns are carried into the winding units. Therefore, yarn guidance occurs laterally between the spooling units stacked on each other, so that the same conditions can be realized in input to both spooling units.

The yarn guide means preferably comprises a deflection roller rotatably provided, and the yarns supplied from the spinning device are guided around the deflection roller. In this case, the deflection roller can be driven further in order to realize as low a winding tension as possible.

In order to realize the smallest possible partition width, according to a preferred refinement of the invention, one or more traversing means (s) are arranged immediately after the yarn guiding means in the yarn path, which traversing means The yarns are guided back and forth in separate spooling units for the purpose of winding to form cross-wound bobbins. The yarn guiding means therefore constitute the start of the traversing triangle directly at each winding station.

In order to achieve the greatest possible flexibility with respect to the increase in bobbin during winding, each spooling unit has a pressure roller which cooperates with the spooling spindle respectively supported in the work area. These pressure rollers are supported on the swivel arm and the swivel arms are connected on the swivel axis.

In this case, in order to maintain the bearing force acting between the pressure rollers and the newly picked bobbins within a predetermined setting value or setting range, a force actuator and a force sensor are assigned to each pressure roller. desirable. The force sensor, together with the rotary drive of the spooling revolver, is in this case connected to the feedback-control circuit via a control device, thus providing a constant bearing force that allows for yield motion while the bobbin size is increased. I will go with you.

In this case, the spooling revolvers of both spooling units stacked on each other can also be preferably driven by a common rotary drive.

In the case of producing a large number of synthetic yarns at the same time, the present invention can be advantageously extended to allocate to the spinning apparatus two additional spooling units which are arranged stacked on each other, at a distance from the spooling units. In this case, the spooling units stacked on each other and the spooling units arranged next to each other are implemented in a mirror structure with respect to each other. Thus, one of the mirror-symmetry planes is formed between the lower spooler and the upper spooler, and the second mirror-symmetry plane is formed perpendicularly between the spooling units perpendicular to the first mirror-symmetry plane.

The yarn feeding is preferably carried out in a second yarn guiding means arranged in a horizontally formed mirror-symmetrical plane between the spooling units. In the yarn path, the two yarn guide means are behind the yarn separator, and the yarn supplied from the spinning device can be separated into two thread sheets by the yarn separator.

According to a preferred refinement, the spacing between the spooling units is used to receive an electrical unit comprising the drive electronics and the control electronics of the spooling unit. In this case, the electrical unit advantageously comprises an operator control panel, by which the entire group of spooling units can be controlled.

For service, it is advantageous in this case that the electrical unit is of mobile design so that the spacing between spooling units can be used as service and operator control passages.

It is preferred that the monitoring devices for monitoring the yarn paths are arranged between the upper spooling units arranged next to each other. In addition to the monitoring apparatus, further processing apparatuses may also be integrated between the spooling apparatuses, which intermtermling the yarns, for example, to increase yarn cohesion.

The spooling units are preferably supported on a winding frame with a closed partition wall, by which the spooling units are separated from each other and surrounded. In this case, at the free end of the spooling spindle the wall has an opening through which the full bobbin can be replaced. Therefore, these enclosures provide a completely climatic environment for winding yarns to form bobbins.

The compact configuration of the device according to the invention is further improved in assigning a further group of spooling units to the group of spooling units. In this case, both groups of spooling units are arranged with their drive side facing each other on a common vertical axis, and enclose therebetween a drive unit having a number of drives assigned to the winding unit. In this way, it is possible to enclose the drives on one side and the coupling of the drives on the other.

To this extent, the device according to the invention as in claim 15 is particularly suitable for achieving the basic purpose. To this end, the winding units arranged in a mirror-symmetric manner are arranged on a common vertical axis. A plurality of drive units having a plurality of drives assigned to the two winding units are provided between the winding units facing each other. As a result, it is possible to realize a small compartment width with a dense configuration of spooling units. In particular, the fact that the drive unit is implemented between the spooling units enables a common enclosure for all drives.

Advantageously, the drive unit has one or more rotary drives which simultaneously drive two spooling revolvers of the spooling units facing each other.

Likewise, spooling spindles facing each other in one axis can be driven by a common spindle drive.

In order to obtain a device for spinning and winding the yarn, which also has a compact configuration in terms of its height, it is preferred that the group of spooling units is immediately behind the take off device with one or more take off godets and a drafting goth. Do. In this case, it is desirable to design one of the goddes to be adjustable between the lay-on position and the working position in order to provide automatic laying-on of yarn directly from the spinning device to the spooler.

In order to match the climatic conditions of such a device, the take-off device is preferably housed in a Godde box, which has an inlet connected to the drop passage of the radiator and an outlet connected to a winding frame with a closed wall. do.

The device according to the invention is basically suitable for producing a variety of synthetic yarns. Therefore, depending on the design of the take-off device, both partial and fully drawn yarns can be manufactured. However, the concept is also fundamentally also preferred for the manufacture of elastic threads, crimped threads or industrial yarns.

An apparatus according to the invention for spinning and winding a plurality of yarns is based on several embodiments, with reference to the accompanying drawings, in more detail below.

1 shows schematically a first embodiment of a device according to the invention.

FIG. 2 is a side view schematically showing a group of spooling units of the embodiment according to FIG. 1.

3 schematically shows another embodiment of an apparatus according to the invention.

4 is a plan view schematically showing a group of spooling units of another embodiment of the apparatus according to the invention.

1 is a schematic diagram of a first embodiment of an apparatus according to the present invention. The device comprises a spinning device 1, a take off device 28 disposed below the spinning device 1, and a spooling unit 2.1 and a spooling unit 2.2 and a spooling device disposed below the take off device 28. It has a group (2) of units.

The spinning device 1 is connected via a melt supply 33 to a melt source, for example an extruder, not shown here. The melt water supply 33 is underneath through a radiation beam 34 having a plurality of radiation nozzles 35 arranged next to one another, preferably in a continuous arrangement. In this embodiment, the spinning nozzles 35 are arranged in a continuous structure extending perpendicular to the stretching plane. Radiation beams 34 are usually arranged with additional melt guiding elements such as distribution lines and pumps.

Below the spinning nozzle 35 is provided a cooling passage 36 which is connected to a cooling air flow generator (not shown). The cooling passage 36 is open to the drop passage 32.

The radiation device 1 is assigned a preference device 37. In this embodiment, the preparation apparatus 37 consists of a preparation roller at the end of the cooling path 32.

However, the preference apparatus 37 may have a number of preference units distributed along the radiation line. Thus, a first pre-preparation of joining the filament bundles to form yarns is preferably made in advance below the cooling passage.

The spinning device 1 is provided with a take off device 28 for pulling out synthetic yarns produced side by side from each spinning nozzle 35. In this embodiment, the take-off device 28 is composed of a take off gode 29 and a drafting goose 30 in which synthetic yarns are partially wound on each.

The configuration of the take-off device 28 basically depends on the kind of yarn to be manufactured. Therefore, the take off device 28 may be made of Gode units in which yarns are wound in multiple layers, for example, to produce a fully drawn yarn. Similarly, take off device 28 may have multiple individual take off feeder rollers, each take off feeder roller guiding only one of the yarns. The take off device 28 may also include additional processing devices such as, for example, a tangle mechanism.

The group of spooling units 2 is located at the end of the spinning line and accepts the manufactured synthetic yarns.

To further describe the group 2 of spooling units, reference is also made to FIG. 2 in addition to FIG. 1. In figure 2 a schematic side view of a group 2 of spooling units is also shown. To this extent, the following description applies to both drawings.

The group 2 of spooling units consists of two spooling units 2.1, 2.2 arranged up and down. The spooling unit 2.1 and the spooling unit 2.2 face each other in a mirror-symmetrical structure, such that a horizontal mirror-symmetric plane 19 is formed between the spooling unit 2.1 and the spooling unit 2.2, It is indicated by a dashed-dotted line. In this case, the spooling unit 2.1 and the spooling unit 2.2 are supported on the winding frame 13. The two spooling units 2.1, 2.2 are of identical construction in terms of the design and function of their mechanical assembly. Therefore, the spooling unit 2.1 has a spooling revolver 5.1 that is rotatably driven, and on this spooling revolver 5.1 two long spooling spindles 6.1, 7.1 are provided.

The spindle drive 15. 1 is assigned to the spooling spindle 6. 1, and the spindle drive 15. 2 is assigned to the spooling spindle 7. Each spooling spindle 6.1, 7.1 has a plurality of spooling tubes 39 arranged next to each other for receiving the bobbin 4. The spooling spindle 6.1 and the spooling spindle 7.1 can be rotated alternately by the spooling revolver 5.1 into the work area and into the change over area. In the situation shown, the spooling spindle 6.1 is in the work area and the spooling spindle 7.1 is in the change over area. In the working area, the spooling spindle 6.1 cooperates with the rotatably installed pressure roller 10.1. For this purpose, the pressure roller 10.1 is supported on the swivel arm 11. 1 which is pivotably connected to the winding frame 13 via the swivel axis 12. The pressure roller 10.1 is assigned a force actuator 18.1 and a force sensor 17.1. The force sensor 17.1 is connected to the control device 16 by its signal line.

The control device 16 comprises electronics for driving and controlling all actuators and drives of the two spooling units 2.1, 2.2. Therefore, the control device 16 is connected to the spindle drive 15.1 and the spindle drive 15.2 and the rotary drive 14, and the spooling revolver 5.1 is driven by the rotary drive 14.

The pressure roller 10.1 is ahead of the traversing means 9.1 and cross-winding for the purpose of forming the bobbins with each of the yarns wound and forming bobbins being guided back and forth by the traversing means. Get

The upper spooling unit 2.2 has identical assemblies in mirror-symmetry with respect to the horizontal mirror-symmetry plane 19. Thus, the spooling spindle 6.2 and the spooling spindles 7.2 are rotatably installed and supported on the spooling revolver 5.2 in a protruding manner. The pressure roller 10.2 is assigned to the spooling spindle 6. 2. The pressure roller 10.2 is rotatably supported on the swivel arm 11.2, which is likewise connected to the winding frame at the swivel axis 12.1. For this purpose, the swivel arm 12.1 is located in the horizontal mirror-symmetry plane 19. The traversing means 9.2 are located before the pressure roller 10.2.

Thanks to the mirror-symmetrical arrangement of the lower spooling unit 2.1 with respect to the upper spooling unit 2.2, a relatively small gap S ₁ is between the spooling spindle 6 and the spooling spindle 6. Is formed. In contrast, a substantially larger distance S ₂ is present between the spooling spindle 7.1 and the spooling spindle 7.2 that are supported in the change over area. This configuration has the particular advantage that the yarns can be fed centrally to the winding station.

In addition, as a result of the full bobbin being guided at the spooling spindle (7.1) and the spooling spindle (7.2), no obstacles occur, so that both the spooling unit (2.1) and the spooling unit (2.2) are very dense at minimum intervals with respect to each other. It can be supported in one way.

As shown in FIG. 2, the spooling revolver 5.1 of the lower spooling unit 2.1 and the spooling revolver 5.2 of the upper spooling unit 2.2 are driven together by the rotary drive 14. In this case, the spooling revolver 5.1 and the spooling revolver 5.2 are in opposite directions of rotation and are coupled to each other by transmission means (not shown).

The yarns are supplied laterally from the take off device 28, next to the spooling unit 2.1 and the spooling unit 2.2. In this case, yarn guide means 8.1 in the form of a deflection roller which deflect together the supplied yarn 3 are implemented in the horizontal mirror-symmetry plane 19. Following the deflection of the yarn in the thread guide means 8.1, the yarn 3 is separated into a lower thread sheet and an upper thread sheet, and is supplied to each of the spooling unit 2.1 and the spooling unit 2.2. In this embodiment, each of the spooling units winds up four yarns 3 simultaneously to form a bobbin 4. Therefore, in the upper spooling unit 2.1 and the lower spooling unit 2.2, a total of eight yarns are simultaneously wound to form bobbins.

A monitoring device 25.1 for monitoring the yarn path is arranged laterally next to the upper spooling unit. The monitoring device 25.1 typically has one trimmer detector per quarter.

In the spinning device 1, the plastic melt is first supplied to the radiation beam 34 via the melt supply 33. The plastic melt is conveyed to the spinning nozzle 35 and extruded under the pressure action of the plurality of nozzle bores of each spinning nozzle 35. For this purpose, each spinning nozzle 35 provides a plurality of filament skeins, denoted by reference numeral 40, as a filament bundle. The filamentary tufts that have just been extruded are then cooled in the cooling passage 36 by the supplied cooling medium. Following cooling of the filament bundles 40 guided next to each other, each bundle is joined to form a yarn 3. The take off of the filament bundle 40 or the yarn 3 is performed by the take off device 28. To this end, the yarns 3 are partly wound around the take off and the drafting gooses 30. Each of the take off swing 29 and the drafting swing 30 can be set to a large speed difference at a small speed difference between the take off swing 29 and the drafting swing 30 according to the type of yarn to be manufactured. . From the drafting gode 30, the yarns are guided vertically to reach the yarn guide means 8.1. The yarns are deflected by the thread guiding means and then separated into an upper threadsheet and a lower threadsheet to reach the spooling unit 2.1 and the spooling unit 2.2.

In order to explain the functions of the spooling unit 2.1 and the spooling unit 2.2, reference is made to FIG. 2 in addition to FIG. 1. In the working situation presented, the threads are respectively wound on the spooling spindles 6.1, 6.2 of the two spooling units 2.1, 2.2.

During the simultaneous winding of the yarn 3 to form the bobbin 4, the pressure roller 10.1 and the pressure roller 10.2 each support the circumference of the bobbin 4 wound on the spooling spindles 6.1, 6.2. . In this case, the supporting pressures of the pressure roller 10.1 and the pressure roller 10.2 are controlled through the control of the force actuator 18.1 and the force actuator 18.2. On the other hand, in order to provide the obtaining operation of the spooling spindle 6. 1 and the spooling spindle 6. 2 while the size of the bobbin 4 is increased, the bearing force applied separately to the force sensor 17.1 and the force sensor 17.2. Measure Within the control of the control device 16, the respective preset point values are respectively matched to the actual values of the measured bearing force, and thus the spooling revolver 5.1 and the spooling revolver so that a constant bearing force is maintained in each case. Activation of the rotary drive to move (5.2) can occur.

However, the lifting operation of the pressure roller 10.1 and the pressure roller 10.2 in the swivel arm 11. 1 and the swivel arm 11.2, in order to obtain a stepwise or continuous obtaining operation of the spooling spindle through activation of the rotary drive 14. It is also possible to detect this.

As soon as the bobbins are completely wound up in the spooling spindle (6.1) and the spooling spindle (6.2), an automatic bobbin change takes place, and the threads thereon, for the purpose of winding new bobbins, 7.2) respectively.

In the case of the apparatus shown in Figs. 1 and 2, a number of yarns can be manufactured while keeping the section width as narrow as possible. In particular, the group 2 of spooling units has only a slightly larger compartment width than when using only one spooling unit.

3 schematically shows another embodiment of an apparatus according to the invention. This embodiment is particularly suitable for producing a large number of yarns and winding them to form bobbins on a minimally small structural space. Since the embodiment according to FIG. 3 is substantially the same as the preceding embodiment, reference is made to the above description and only the differences will be described below.

The embodiment according to FIG. 3 consists of a spinning device 1, a take off device 28, and a group 2 of spooling units. The spinning device 1, the take off device 28, and the group 2 of spooling units are connected to each other via a frame wall closed to the outside. The design of the spinning device 1 is the same as that of the preceding embodiment. Adjacent to the distal end of the drop passage 32 is a Gode box 31. The take off swing 29 and the drafting swing 30 are held in this swing box 31. The take off gode 29 is movably supported on the positioning device 38 for guiding the take off gode 29 between the ready position (indicated by the broken line) and the work position. In this case, the positioning device 38 may be composed of a take-off swing 29 or, alternatively, a rotor in which both the swing 29 and the swing 30 are installed and movable.

Adjacent beneath the Godde box 31 is a winding frame 13, in which case the winding frame consists of a closed partition wall 26. The group 2 of spooling units is supported on the winding frame 13. In this case, a total of four spooling units (2.1, 2.2, 2.3, 2.4) are supported in a mirror-symmetrical structure with respect to each other. The lower spooling units 2.1, 2.3 are configured mirror-symmetrically with respect to the upper spooling units 2.2, 2.4. Therefore, a horizontal mirror-symmetry plane 19 is formed between the lower spooling units and the upper spooling units. To be orthogonal to this, a vertical mirror-symmetry plane 20 is formed between the right spooling units 2.1, 2, 2 and the left spooling units 2.3, 2.4 to form a mirror-symmetry plane. Each of the spooling unit 2.1 and the spooling unit 2.4 has the same configuration, and their configuration corresponds to the configuration of the embodiment according to FIG. 1 described above, and thus, the above description is referred to, and only the differences thereafter will be described. would.

A space is formed between the right spooling units 2.1, 2.2 and the left spooling units 2.3, 2.4. In this case, between the lower spooling units 2.1, 2.3, an electric unit 23 including a control device having control electronics and driving electronics is arranged.

The operator control panel 24 is embodied on the electrical unit, by which it is possible to control all the spooling units 2.1 to 2.4. The electric unit 23 is of a mobile design, so that the space between the right spooling units 2.1, 2.2 and the left spooling units 2.3, 2.4 can be used as the operator control passage.

For yarn guidance, two idler roller shaped yarn guide means (8.1, 8.2) arranged adjacent to each other in a horizontal mirror-symmetric plane (19) are provided with left spooling units (2.1, 2.2) and right spooling unit (2.3, 2.4) It is supported in the space between them. In the yarn path, there is a yarn separator (21) in front of the yarn guide means (8.1) and the yarn guide means (8.2), which separate the yarns from the drafting core (30) into threadsheets (22.1, 22.2). do. Each thread sheet 22.1, 22.2 is assigned a monitoring device 25.1, 25.2, which is arranged in the space between the upper spooling units 2.2, 2.4.

In the winding frame 13, the spooling units 2.1 to 2.4 are separated from each other by the partition wall 26 and are completely surrounded at their ends by an additional partition wall. In this embodiment, the end partition walls are shown by way of example only for the spooling unit 2.4. In this case, the front partition wall 41 has a bobbin opening 42, through which bobbin openings can exchange full bobbins. During operation, the bobbin opening 42 is closed with a cover, not shown here. Therefore, it is possible to create a completely climated environment in each spooling unit (2.1 to 2.4). Guiding of the yarn is in this case carried out through openings of suitable shape.

The embodiment shown in FIG. 3 is preferably suitable for producing partially drawn yarns. At the start of the process, the take off goe 29 is first rotated to the ready position, so that the threadsheet falling contactlessly from the spinning apparatus falls into the yarn feed of the winding frame. The threadsheet can in this case be accommodated by a collecting hopper in the lower region of the winding frame, for example with an associated suction extraction system. The take off gode 29 is then rotated from the ready position to the working position. Since the threadsheet is supported on the take-off swinging 29 and the drafting hanging 30, the thread 3 of the threading sheet will be evenly distributed on the periphery of the hanging 29 and the hanging 30. In order to assign the threadsheets to the individual spooling devices, the yarn separator 21 is first activated in the upper region of the winding frame 13, the yarn separator being connected to each other, for example in a comb type manner. It can be configured as a guide element, thereby separating the threadsheet into a left threadsheet 22.2 and a right threadsheet 22.1. Both the thread seat 22.1 and the thread seat 22.2 are then divided by the second auxiliary device into upper and lower partial thread seats, respectively, which are held by the suction extraction device assigned to each of the spooling units. For this purpose, the thread sheets 22.1, 22.2 are guided by yarn guide means 8.1 and yarn guide means 8.2. The upper and lower partial threadsheets then formed are then directed directly to the assigned spooling units (2.1 to 2.4).

The laying operation of the spooling units 2.1 to 2.4 preferably takes place simultaneously, thus obtaining uniform yarn guidance of all yarns. The spooling operation takes place in each of the illustrated spooling units 2.1 to 2.4 as in the above description with regard to the embodiment according to FIG. 1, no further description of which is made at this point. During winding the yarns, the spooling units (2.1 to 2.4) may be operated separately or may be operated simultaneously. The spooling revolvers 5.1, 5.2 and the spooling revolvers 5.3, 5.4 are each preferably driven by a common rotary drive.

In order to double the number of yarns produced at the same time, Fig. 4 shows another embodiment of the apparatus according to the invention, in which case only the top view of the group 2 of spooling units is shown. In comparison with the embodiment according to FIG. 3, the group 2 of spooling units is made by spooling units each arranged in a mirror-symmetrical structure with an axial extension. In this case, the drive side of each of the two spooling units 2.1, 2.2 faces each other in a mirror-symmetrical structure, so that the drive unit 27 is surrounded between the spooling unit 2.1 and the spooling unit 2.2. . The drive unit 27 comprises a drive of a spooling revolver and a spooling spindle of two spooling units 2.1, 2.2. In this case, both the drive of the spooling revolvers and the drives of the spooling spindle can be easily coupled to each other. Simultaneous operation of the spooling unit 2.1 and the spooling unit 2.2 facing each other on the vertical axis can be obtained in an easy manner. The design of the spooling unit is the same as the spooling unit of the embodiment according to FIG. 1 described above.

The embodiment shown in FIG. 4 is particularly suitable for integrating a maximum number of devices in one installation in one installation. Therefore, a total of eight spooling units can be combined to form one group. The compact construction of the spooling unit with a simultaneous working manner makes it possible to control or combine the multiple drives of the spooling unit together to form one drive. In a group of spooling units, yarn guidance, which guides the yarn from the plane of symmetry or from the center of symmetry, allows each spooling unit to produce the same bobbin under the same conditions. Thus, the device according to the invention is particularly suitable for winding synthetic yarns at winding speeds higher than 6,000 m / min.

In addition, the design of the spooling unit shown in the embodiment according to FIGS. 1 to 4 is exemplary. In essence, any known traversing system can be used as the traversing system, such as a flyer traversing system or a reversing threaded shaft traversing system. Thus, the traversing means of the stacked arrangement of spooling units may also advantageously be combined in such a way that only one drive is required. Likewise, the installation of the pressure roller is also exemplary. Therefore, the pressure rollers, alone and independently, can be supported in both stationary and movable manners. Thus, the present invention also encompasses a similar design of spooling units which are supported in a special mirror-symmetrical structure with respect to each other.
