Description

  The present invention relates to an apparatus for melt-spinning a plurality of yarns described in the superordinate concept section of claim 1.

  An apparatus of this type is known from EP 0 285 736.

  In this known apparatus, a plurality of spinning nozzles are arranged in two parallel rows adjacent to each other for melt spinning synthetic fiber yarns. The spinning nozzle is arranged in a heated spinning bar. The spinning nozzles are connected to a melting source, whereby one multifilament yarn is pumped from each spinning nozzle. The spinning nozzle is arranged in a heated spinning bar. A cooling device having double cooling shafts (cooling towers or cooling vertical holes) is formed below the spinning bar, whereby one separate cooling shaft is arranged corresponding to each nozzle row. After cooling, the plurality of yarns of the two nozzle rows are guided in a common collection plane and passed as a yarn group into a processing device in one or more processing stages. After processing, the plurality of yarns are wound around a bobbin in a winding device in a general form.

  In order to obtain as high a productivity as possible when spinning a plurality of yarns, thread breaks in a plurality of yarn paths in such a type of device are monitored, thereby making the process interruption as short as possible. In addition to pure monitoring, an analysis to find possible causes of thread breakage is desired. However, in the known apparatus, there is a problem that a plurality of yarns extruded from the spinning nozzle are all collected together in one common collecting plane. As a result, the yarn path between the spinning nozzle and the winding device is always formed differently in the processing device, so that the results obtained for multiple yarn paths cannot be assigned for further analysis. .

  Accordingly, an object of the present invention is to improve an apparatus for melt-spinning a plurality of yarns of the type described at the beginning, so that the yarns extruded from the spinning nozzles of the two nozzle rows are formed on the bobbin in the yarn path. It is to be able to always identify until winding.

  According to the present invention that solves this problem, the plurality of yarns of one nozzle row (A) and the plurality of yarns of the other nozzle row (B) are predetermined in the collection plane by at least one guide means. It was continuously held in one yarn group.

  When producing a synthetic fiber yarn, a result confirmed for each yarn path, for example, yarn breakage is transferred to one of a plurality of spinning nozzle rows or one of a plurality of spinning nozzles of a plurality of spinning nozzle rows. In order to be able to be assigned, according to the invention, a plurality of yarns are held in the collection plane in a predetermined sequence by the guide means. As a result, a predetermined position is assigned to each of the plurality of yarns in the yarn group. The longer a group of yarns are guided together through each processing stage of the processor, the more each yarn can be assigned to a respective spinning nozzle based on its position at any point in time.

  According to another advantageous embodiment, a series is formed in which a thread group of a plurality of nozzle rows is guided in a common plane next to the thread groups of adjacent nozzle rows. In this case, the partial yarn groups are drawn and guided from the collecting plane by one pulling godet in common or by two pulling godets separately. For this purpose, the guide means advantageously have two groups of yarn guides, which are arranged corresponding to the partial yarn groups. The yarn guide is held by the guide means in a common guide plane or in two adjacent guide planes.

  However, it is also possible to guide the plurality of yarns of the two nozzle rows alternately and side by side in the collection plane. It is also basically possible to obtain different changes in the yarn sequence.

  When producing a plurality of yarns from two parallel nozzle rows, it is particularly necessary to take care that the displacement of the yarn guide and in particular the plurality of yarns is kept as uniform as possible in all the yarns of the yarn group. This is because otherwise, different tensions act, which in turn causes quality variations. Therefore, according to a particularly advantageous embodiment of the invention, the collection plane is formed in the middle of parallel nozzle rows. The plurality of yarns in the two nozzle rows are similarly turned to guide in the collection plane.

  Based on a plurality of yarns in one spinning point, the winding device is preferably a winding machine with two winding units or a winding machine with one winding unit at each spinning station. Formed by. As a result, the winding unit suitable for high winding speeds can be compactly formed.

  In order to wind up the plurality of yarn groups in the nozzle row as evenly as possible on the bobbin, the yarn group drawn after the processing is wound on the bobbin with a predetermined distribution of the plurality of yarns in the nozzle row and the plurality of yarns in the nozzle row In addition, it is proposed to divide into a plurality of winding units. In this case, the distribution is chosen in an advantageous manner such that all the threads of one of the two nozzle rows are all wound on the bobbin spindle of one winding unit.

  In order to achieve as narrow a division of the nozzle rows as possible, according to an embodiment of the present invention, the cooling device has at least one double cooling shaft, and the double cooling shaft has a separate cooling shaft for each nozzle row. A central pressure chamber is provided between the plurality of cooling shafts. In this case, blown air is supplied to a central pressure chamber formed in the double cooling shaft for supplying the cooling shaft, through an air passage arranged side by side on the machine longitudinal direction side. The air path can be connected via a transverse sleeve to the pressure chamber of the double cooling shaft.

  The two cooling shafts of the double cooling shaft are opened in one common drop vertical hole to ensure that the yarn groups arranged corresponding to the nozzle rows can enter the collecting plane with high running quietness. is doing.

  In this case, advantageously, each yarn of the two yarn groups is connected by two separate smoothing devices before entering the collecting plane.

  The advantageous embodiment of the invention is in particular divided into a plurality of groups by forming the spinning nozzles into a plurality of longitudinal modules, in which case the arrangement of the spinning nozzles in each group and the temperature regulation of the spinning nozzles remain uniform. It is characterized by being. Due to the passage formed between the longitudinal modules, each longitudinal module can be operated from two machine longitudinal sides. A particularly short spinning start time is thereby realized at the start of the process or after the process is interrupted. This is because one worker can supply the spinning nozzles of two nozzle rows of one vertical module.

  The spinning nozzles of the longitudinal module are advantageously divided into a plurality of spinning stations, in which each spinning station is associated with one double cooling shaft of the cooling station, which double cooling shaft is connected to each nozzle row. Each having one cooling shaft. As a result, it is possible to intensively cool the multi-yarn that has just been pressed out. In this case, the spinning station may have up to 12, 16 or 20 spinning nozzles divided into two nozzle rows. In this case, for example, four spinning stations form one longitudinal module.

  According to an embodiment of the invention, the plurality of vertical modules are each formed by a box-like nozzle support, which is heated by a heat transfer medium and has at least one end facing the passage. If the heat transfer medium is supplied via the inlet and / or the outlet for the heat transfer medium in the section, it is particularly advantageous for the temperature regulation of the spinning nozzles uniformly in the longitudinal module. is there. In addition, if the box-shaped nozzle support has a slightly small inclination aligned in the machine longitudinal direction, a heat transfer medium circulation path aligned in the vertical direction can be realized in a simple form. Another advantage is that the free space formed by the passages in this device can be used for the supply line and the supply device.

  Next, an embodiment of an apparatus according to the present invention for melt spinning a plurality of yarns will be described in detail with reference to the drawings.

In this case, FIG. 1 shows a side view of the entire device over the machine length, FIG. 2 shows the part of the device shown in FIG. 1 with two spinning stations, and FIG. 1 shows a spinning station cross-sectioned in a transverse direction perpendicular to the longitudinal direction. The following description applies to all drawings unless otherwise indicated.

  This device is held by a machine frame 1 having a plurality of layers, which machine frame 1 is shown only as a lateral support in FIGS. 1, 2 and 3. On the upper floor of the machine frame 1, a plurality of vertical modules 2.1, 2.2 and 2.3 are arranged side by side along the machine longitudinal direction side. Each of the longitudinal modules 2.1, 2.2 and 2.3 has a plurality of spinning nozzles 4, and these spinning nozzles 4 are arranged in two nozzle rows A and B parallel to each other.

  As shown in FIG. 1, the longitudinal modules 2.1, 2.2 and 2.3 arranged along the longitudinal direction of the machine are separated from each other by a passage D. In this case, the passage D between the longitudinal modules 2.1, 2.2 and 2.3 extends over all levels of the machine frame 1.

  The longitudinal modules 2.1, 2.2 and 2.3 are formed by box-shaped nozzle supports 8.1, 8.2 and 8.3, respectively. In the box-shaped nozzle supports 8.1, 8.2 and 8.3, the spinning nozzle 4 arranged corresponding to the vertical module and the distribution pump 5 connected to the spinning nozzle 4 are not shown in detail. And a melt distributor. Nozzle bodies 8.1, 8.2 and 8.3 are each connected to the heat transfer circuit for heating the component supplying the melt. For this purpose, the inflow part 11 and the outflow part 12 are arranged on the end face side 33 of the nozzle supports 8.1, 8.2 and 8.3. The outlets 12 are respectively formed in the lower regions of the nozzle supports 8.1, 8.2 and 8.3, in which case the nozzle support is held in a slightly tilted state, The resulting heat transfer medium can be derived in a simple format. The supply lines of the inflow part 11 and the outflow part 12 are formed in the region with the passage D in an advantageous manner.

  The device for producing the melt or the device for dispensing the melt arranged above the longitudinal modules 2.1, 2.2 and 2.3 is not shown. For example, the melt is supplied by a single extruder to the components of the plurality of longitudinal modules that guide the melt.

  Each longitudinal module 2.1, 2.2 and 2.3 is divided into a plurality of spinning stations. The structure and configuration of the spinning station will be described in detail below with reference to the longitudinal module 2.1 shown in FIGS.

  Each spinning station 3.1, 3.2, 3.3 and 3.4 has a total of twelve spinning nozzles 4, which are uniformly arranged in two nozzle rows A and B. It is divided into The spinning nozzles of the nozzle arrays A and B are each connected to the distribution pump 5. Each distribution pump 5 has a drive shaft 6, and this drive shaft 6 is connected to a drive device (not shown). The polymer melt is fed to the distribution pump 5 via one melt connection 7 each.

  In the embodiment shown in FIGS. 2 and 3, the spinning nose of the spinning station is fed by two separate dispensing pumps. However, if, for example, 6 or 8 spinning nozzles are provided in two nozzle rows in total, all the spinning nozzles may be supplied by one distribution pump. In this case, the number of spinning nozzles per spinning station is shown as an example.

  A cooling device 13 is arranged under the nozzle supports 8.1, 8.2 and 8.3. The cooling device 13 has one double cooling shaft (double cooling tower) for each spinning station. Double cooling shafts 14.1, 14.2, 14.3 and 14.4 are arranged correspondingly to the spinning stations 3.1, 3.2, 3.3 and 3.4 of the first longitudinal module 2.1. Yes.

  As shown in FIG. 3, the double cooling shafts 14.1 to 14.4 are formed by two separate cooling shafts (cooling towers) 15.1 and 15.2, which are The nozzle rows A and the nozzle rows B are arranged corresponding to the spinning nozzles 4. Between the cooling shafts 15.1 and 15.2, the double cooling shafts 14.1 to 14.4 each have one pressure chamber 16. Blowing walls 17.1 and 17.2 are formed between the cooling shafts 15.1, 15.2 and the pressure chamber 16, so that a cooling air flow directed in the transverse direction is provided on the cooling shaft 15. 1 and 15.2. The pressure chamber 16 of the double cooling shafts 14.1 to 14.4 is connected to the central air passage 20 via an air connection 18 and a transverse sleeve 19 in the lower region. The air passage 20 extends laterally parallel to the machine longitudinal direction and feeds all the double cooling shafts of the cooling device 13. A transverse sleeve 19 connected to the air passage 20 is arranged between the spinning stations in the lower region of the cooling device 13. The lower regions of the cooling device 13 are each formed by drop vertical holes, the drop vertical holes for the first vertical module 2.1 are denoted by 34.1, 34.2, 34.3 and 34.4. ing. In this case, the falling vertical holes 34.1 to 34.4 have a shape that tapers downwards, so that the free chamber formed between the spinning stations is used to receive the transverse sleeve 19. Is done. By supplying blown air from the side, a special advantage is obtained that the spinning nozzle arrays A and B can be arranged as close as possible to each other. Thereby, an air supply part arranged through a central plane extending between the nozzle rows A and B can be avoided.

  As shown in FIG. 3, one smoothing device 23.1 and 23.2 is arranged corresponding to each cooling shaft 15.1 and 15.2, respectively, in the lower region of the double cooling shaft 14.1. ing. In this case, the smoothing device 23.1 is arranged corresponding to the nozzle row A, whereby the multifilament yarn 9 discharged from the nozzle row A is smoothed by the smoothing device 23.1 at the end of cooling. Agent is applied. Similarly, the yarn 10 discharged from the spinning nozzles of the nozzle row B is smoothed by the smoothing device 23.2. After smoothing, the yarns 9 and 10 are assembled into a yarn group at a common collection plane 35. For this purpose, the guide means 21 is arranged on the exit side of the drop vertical hole 34.1. In this case, the guide means 21 maintains a predetermined continuity of the yarn in the yarn group 22. Hereinafter, the distribution of the yarns 9 and 10 in the yarn group 22 will be described in detail.

  As shown in FIGS. 2 and 3, a processing device 24 is disposed under the cooling device 13. The processing apparatus 24 has a plurality of processing modules 36, and one of the processing modules 36 is arranged corresponding to each spinning station. For example, in the first longitudinal module 2.1, depending on the yarn type to be manufactured, the spinning stations 3.1 to 3.4 have a godet, a godet device, a mixing device, a yarn cutting device, a heating device. A smoothing device (Treatment device) and other devices are installed. In the illustrated embodiment, two dead 25.1 and 25.2 are shown as an example for clarity.

  In the processing apparatus, the collecting plane 35 on which the yarn group 22 is guided is rotated by 90 ° on the way from the guide means 21 to the first godet 25.1. This guides the yarn in the godet 25.1 in a plane aligned substantially transverse to the machine longitudinal direction.

  A winding device 26 is disposed under the processing device 24, and the winding device 26 includes a plurality of winding units. Accordingly, two winding units 27.1 and 27.2 are arranged corresponding to each spinning station. In this case, the winding units 27.1, 27.2 are configured as winding machines or are configured as two winding machines arranged in parallel with each other. In the illustrated embodiment, winding units 27.1, 27.2 are formed in winding machines 37.1 and 37.2, which are driven synchronously, respectively. Thereby, the winding device 26 is formed by a plurality of winding machines. In each of the winding units 27.1 and 27.2, the yarns of the yarn group 22 are each wound on one bobbin 32. For this purpose, a plurality of bobbins 32 are attached to the bobbin spindle 29.1. The bobbin spindle 29.1 is held by one bobbin revolver 28 in each winding unit 27.1 and 27.2. The bobbin revolver 28 has a second bobbin spindle 29.2 that is offset by 180 °. By rotating the bobbin revolver, the plurality of yarns of the yarn group 22 are continuously wound on the bobbin. The pressure roller 30 is applied to the outer peripheral surface of the bobbin 32. A traverse device (traverse device) arranged in front of the pressure roller for reciprocating the yarn to form the traverse bobbin is not shown in detail here.

  In order to divide a plurality of yarns of the yarn group 22 at a position before the yarn group 22 is introduced into the winding units 27.1 and 27.2, one double guide rail 31 is provided for each spinning station. . In this case, the arrangement according to the spinning nozzles A and B or the spinning nozzles of the nozzle rows A and B is maintained by the double guide rail 31. The following explains how to divide the yarn group and maintain the selected arrangement.

  In the apparatus shown in FIGS. 1, 2, and 3, the cooling device 13, the processing device 24, and the winding device 26 are configured in the same manner as the vertical modules 2.1, 2.2, and 2.3, respectively. ing. During operation, one or more melt sources generate a polymer melt, for example based on polyester. The polymer melt is guided to the distribution pump 5 of the longitudinal modules 2.1, 2.2 and 2.3 via a distribution system not shown in detail. By means of this distribution pump, the polymer melt is fed to the associated spinning nozzle 4 by overpressure. Each spinning nozzle 4 has a plurality of nozzle holes on the lower side thereof, and a bundle of fine filaments is pressed out for each yarn through these nozzle holes. Accordingly, each spinning nozzle of this device produces one multifilament yarn. Next, the yarn spun for each nozzle row in the spinning station is cooled in a double cooling shaft arranged for each spinning station, and after cooling, gathers in one common yarn group 22 together with a plurality of yarns in adjacent nozzle rows. Be made. Before being assembled, the plurality of yarns 9 in the nozzle row A and the plurality of yarns 10 in the nozzle row B are wetted with liquid by the associated smoothing devices 23.1 and 23.2 and then spun by the guide means 21. The yarn group 22 is assembled for each station. The plurality of yarns of the yarn group are guided to the processing module 36 at a narrow interval from each other, and then wound on the bobbin by the two winding units after the processing.

  In this type of device, on the one hand, the spinning nozzle can be regularly arranged, and on the other hand, the newly spun yarn can be threaded by the operator after the process is interrupted or at the start of the process. Depending on the arrangement of the spinning nozzles, it is possible in a simple manner to quickly switch the machine longitudinal side by the operator. As shown in FIG. 3, the operator can operate the longitudinal modules 2.1, 2.2 and 2.3 from both sides in the machine longitudinal direction in a central hierarchy. For this purpose, the longitudinal side can be exchanged by the passage D between the vertical modules. Based on the short path length between the longitudinal sides, even if the yarn breaks at one spinning station, this can be handled with very short process interruptions.

  Another advantage of this device is that a supply line and an auxiliary device, such as a smoothing agent supply device, can be integrated in the channel D between adjacent longitudinal modules in an advantageous manner. This provides a compact device that saves space. Thus, for example, the vertical modules in the second row can be placed immediately next to the apparatus shown in FIG. The entire building can therefore advantageously be provided with a plurality of vertical modules arranged in rows of this type. This saves 30-40% of the required space compared to conventional devices.

  When monitoring a device of this type, the yarn path of each yarn is monitored in a general format. Sensor means are provided for transmitting information to the control device in response to a case where a yarn break is confirmed. This type of monitoring method is particularly important for producing high quality yarns throughout the device. However, for such monitoring and analysis of the results occurring in the yarn path, it is necessary to know at which spinning station or from which spinning nozzle the yarn was produced. If this is known, when a plurality of yarns are gathered from two nozzle rows, a predetermined sequence can be maintained, whereby the entire yarn path can be traced back from the winding device to the spinning nozzle.

  To this end, FIGS. 4 and 5 show a guide for guiding a plurality of yarns in two rows of nozzles in a spinning station so that they can be used in the embodiment of the apparatus of the invention shown in FIG. An embodiment of the guide means is shown schematically. The partial views and spinning stations in FIGS. 4 and 5 are, for example, the spinning station indicated by reference numeral 3.1 in FIG. In this case, FIG. 4 shows a schematic view of the spinning station until the yarn group 22 is formed, and FIG. 5 schematically shows a cross-sectional view of the spinning station. The following description applies to either of the two drawings unless it is referred to as either of FIG. 4 or FIG.

  In the partially illustrated nozzle support 8.1, a total of 12 spinning nozzles are uniformly divided into two nozzle rows A and B. Correspondingly, six yarns are produced from the spinning nozzle 4 of the nozzle row A, these yarns being denoted by 9. The plurality of yarns 10 in the nozzle row b are correspondingly pressed out by the spinning nozzles in the nozzle row B. In a cooling vertical hole (not shown), the yarns 9 and 10 are guided parallel to each other to the smoothing devices 23.1 and 23.2. In this case, the smoothing devices 23.1 and 23.2 are shown as smoothing rollers. However, the smoothing device may be formed by individual smoothing pins, each moistening one yarn.

  After wetting the yarns 9, 10, these yarns are guided to a common collection plane 35. On the collecting plane 35, the yarns 9 and 10 are assembled into one yarn group 22 by the guide means 21. In the yarn group 22, twelve yarns arranged side by side have a predetermined continuity. In the embodiment shown in FIG. 4, these yarns 10 are guided side by side as a partial yarn group in the nozzle row B and the yarn 9 in the nozzle row A, respectively. The guide means 21 arranged under the drop vertical hole is formed by a yarn guide rail having two groups of yarn guides 38. Among these groups, one group of yarn guides 38 is arranged corresponding to the yarn 9 of the nozzle row A, and the other group of yarn guides 38 is arranged corresponding to the yarn 10 of the nozzle row B.

  As shown in FIG. 5, the collection plane 35 is arranged in the central region between the spinning nozzles of the nozzle row A and the spinning nozzles of the nozzle row B. As a result, the yarns of the two nozzle rows can be uniformly changed. This makes it possible to produce yarns having the same physical properties in an advantageous manner.

  FIG. 5 shows another embodiment of guide means for dividing a plurality of yarns in a yarn group that can be used in the embodiment of the device according to the invention shown in FIG. Since the embodiment shown in FIG. 5 is the same as the embodiment shown in FIG. 4, only the differences will be described instead. When dividing the yarn 9 of the nozzle row A and the yarn 10 of the nozzle row B, the guide means 21 defines the continuity in the yarn group 22 through the separate yarn guide 38. This continuity guides the yarns 9 of the nozzle row A and the yarns 10 of the nozzle row B alternately side by side. Thereby, continuous AB, AB, and AB are obtained according to the nozzle row. As a result, the transfer of the yarn group 22 into the processing apparatus is defined so that the origin of the yarn can be known at any point in the processing and at any time.

  In the production of synthetic fiber yarns, the yarn quality is markedly defined by the respective winding process. Therefore, in order to produce uniform quality yarns, a predetermined corresponding arrangement between the spinning nozzle and the winding station is advantageous. FIG. 6 shows how the yarns of a group of threads are divided into individual winding units after processing, for example using the embodiment of the winding unit used in the device shown in FIG. Yes.

  In this case, the winding units 27.1 and 27.2 are formed in the winding machine. The winder has two bobbin revolvers 28.1 and 28.2. Each bobbin revolver has two bobbin spindles 29.1, 29.2. One press roller 30.1, 30, 2 is arranged corresponding to each of the bobbin revolvers 28.1 and 28.2. Double guide rails 31 are provided on the upper side of the pressure rollers 30.1 and 30.2. The double guide rails 31 are parallel to the take-up bobbin and are provided in each longitudinal direction on each of the winding stations. Has a thread guide. Such a type of double winder is basically known and is described, for example, in German Offenlegungsschrift 10045473. Therefore, reference should be made to this specification for details of the winder.

  After processing, the yarn group 22 is divided into winding units 27.1 and 27.2 by a double guide rail 31 according to a predetermined corresponding arrangement. In this case, the yarn 9 in the nozzle row A and the yarn 10 in the nozzle row B are separated from the yarn group 22 and supplied separately to the winding units 27.1 and 27.2, respectively. Thereby, the yarn 9 of the nozzle row A is wound up on the bobbin by the bobbin spindle 29.1 of the winding unit 27.1, and the yarn 10 of the nozzle row B is bobbed by the bobbin spindle 29.2 of the winding unit 27.2. Rolled up. Thereby, each yarn can be identified at each position in the yarn group 22 between the spinning nozzle and the winding device. This makes it possible to monitor and control the apparatus with simple means.

  The processing device and winding device in the apparatus of FIG. 1 are shown as an example. For example, all yarns of the spinning station can be received in common by a winder with a single winding unit. The configuration of the processing equipment consists of fully drawn yarns (FDY), pre-oriented yarns (POY), or highly oriented yarns (HOY), or windings. Based on which crimped fibers (BCF) are produced. Therefore, the processing apparatus can be selectively equipped with units for these.

  FIGS. 8 and 9 show another embodiment of a processing module that can be used, for example, in the spinning station shown in FIG.

  In the embodiment shown in FIG. 8, the processing module of the spinning station is formed by two godet units with a total of four godets. The first godet unit including the godets 25.2 and 25.2 is arranged corresponding to the partial yarn group having the plurality of yarns 9 in the nozzle row A. The second godet unit having godets 25.3 and 25.3, which are arranged mirror-symmetrically with respect to the first godet unit, is a partial yarn group including a plurality of yarns 10 in the nozzle row B. Corresponding arrangement. The partial yarn group is guided by a double guide rail 31. This guide may be implemented directly at the collection plane by the guide means. For this reason, the two groups of yarn guides are held on both sides of the guide rail, so that the partial yarn groups are separated simultaneously when being fed out of the spinning device.

  The first winding unit 27.1 is arranged corresponding to the godets 25.1 and 25.2, and the first winding unit 27.2 is arranged corresponding to the godets 25.3 and 25.4. In this case, the winding units 27.1 and 27, 2 may be formed by one winder 37 as shown or by two separate winders. In this embodiment, the winder 37 is configured substantially the same as the embodiment shown in FIG. 7, but unlike the embodiment shown in FIG. 7, the two winding units 27, 1 and 27. 2 are arranged in parallel symmetrically with each other, the bobbin revolvers 28.1 and 28.2 are driven in the same rotational direction to wind up the bobbin 32.

  The embodiment of FIG. 8 shows the arrangement of the processing devices that are guided with as little turning angle as possible when the yarn is drawn from the spinning device. The godet unit and the winding unit are driven synchronously in an advantageous manner. In this case, a double unit may advantageously be used.

  In the embodiment shown in FIG. 9, the processing modules are formed by two godet units arranged side by side symmetrically. The first godet unit having godets 25.1 and 25.2 is arranged corresponding to the partial yarn group having a plurality of yarns 9 of nozzle row A, and has godets 25.3 and 25.4. The second godet unit is arranged corresponding to a partial yarn group including a plurality of yarns 10 of the nozzle row B. In this case, guide means 21 is arranged immediately before these godet units, and this guide means is formed by guide rails comprising two groups of yarn guides 38. These groups of yarn guides 38 are arranged on the collecting plane so that the partial yarn groups can be separated simultaneously.

  For winding the bobbin, the yarns 9, 10 are received by a winder according to the embodiment shown in FIG. 7 or by a winder according to the embodiment shown in FIG.

  In order to keep the deflection of the yarn as small as possible, the godet unit with the godets 25.1 and 25.2 and the godet unit with the godets 25.3, 25.4 are in a plane shifted from each other. Has been placed. In this case, the magnitude of the deviation between the godet units can be guided to the godets 25.1 and 25.3 arranged behind without separating the yarns spatially after separating the partial yarn groups. So that it is selected.

  The individual structure and configuration of the processing apparatus shown in the above embodiment are shown as an example. Basically, a pair of godets and a mixing device for guiding multiple wound yarns may be provided in front of, between or behind a plurality of godets. The processing device may advantageously be combined with auxiliary means such as, for example, a yarn cutter, a yarn suction device and a monitoring sensor.
