Description

  The present invention relates to a false twisting machine that performs false twisting on a yarn.

  A false twisting machine that performs false twisting on a yarn generally includes a first heating device, a cooling device, and false twisting arranged in order from the upstream side in the yarn traveling direction along a yarn path from a yarn feeding unit to a winding device. The apparatus and the 2nd heating apparatus are provided. As the layout of the false twisting machine, the following is disclosed.

  In Patent Document 1, a false twisting device and a second heating device are provided on a main machine stand, and a winding device is provided on a take-up stand that is disposed opposite to the main machine stand with a work space therebetween. The first heating device and the cooling device are provided above and the false twisting machine in which the winding device is arranged in three stages is described.

  Further, in Patent Document 2, a winding device and a second heating device are arranged side by side on a main machine base, a yarn supplying unit is provided at a position sandwiching the main machine table and a work space, and a yarn supplied from the yarn supplying unit Describes a false twisting machine that passes through the first heating device, the cooling device, and the false twisting device and is sent to the second heating device while traveling above the work space.

JP-A-8-325866 (FIG. 6) JP 52-31149 A (FIG. 2)

  However, in the false twisting machine described in Patent Document 1, since there are only three winding devices, it has been desired that more packages can be wound in a short time. Therefore, it is conceivable to increase the number of winding devices of the false twisting machine. However, if the number of winding devices is simply increased in the vertical direction, the height of the winding table increases, and the first heating is performed. If the positions of the apparatus and the cooling apparatus are not increased, the bending of the yarn from the feed roller to the first heating apparatus will increase. When the bending of the yarn increases, the stress on the yarn increases and the quality of the yarn decreases. Further, if the first heating device and the cooling device are made high so that the bending angle of the yarn from the feed roller to the first heating device is not changed, the total height of the false twisting machine becomes high, and the false twist The size of the room that accommodates the processing machine increases, and the temperature adjustment cost in the room increases.

  In addition, in the false twisting machine described in Patent Document 2, a four-stage winding device has been proposed. However, a package that is wound by the winding device and is fully wound is a second heating device. It will be taken out to the work space on the opposite side. However, it is difficult to secure a spurt for storing a full-package in the work space because the threading workability deteriorates.

  Accordingly, an object of the present invention is to provide a false twisting machine that can secure a space for storing a full-package and can take up many high-quality packages in a short time.

  The false twisting machine according to the present invention includes a yarn feeding unit, a plurality of feed rollers that run the yarn supplied from the yarn feeding unit, a winding device that winds the running yarn, and the winding unit that feeds the winding from the yarn feeding unit. A first heating device, a cooling device, a false twisting device, and a second heating device arranged in order from the upstream side in the yarn traveling direction along the yarn path to the take-up device, the false twisting device and the second heating device. 2 heating device is provided in the main machine base, the winding device is provided in a winding table facing the main machine base with a work space, and further, A first feed roller for sending the yarn supplied from the yarn supplying section to the first heating device is disposed, and the first heating device and the cooling device are provided above the work space, The winding table is provided with four winding devices.

  According to the false twisting machine of the present invention, the winding device is arranged in four stages, so that the number of packages that are wound in parallel is larger than in the case where three or less winding devices are arranged. Therefore, many packages can be wound up in a short time. In addition, the full package can be taken out in a vacant space opposite to the work space, and a space for storing the full package can be secured while securing the work space. As described above, a large number of full-packages can be stored in the vacant space, and the frequency of picking up the full-packages is reduced, thereby improving work efficiency. Furthermore, even if the number of winding devices increases in the vertical direction and the height of the winding table increases, the first heating device and the cooling device are above the work space. Don't be. Therefore, the height of the entire false twisting machine does not increase, the size of the room for housing the false twisting machine remains the same, and the temperature adjustment cost in the room does not increase. In addition, if the first heating device and the cooling device are arranged so as to extend above the take-up table, the first feed roller is provided on the take-up table. The bending of the yarn up to the device becomes large. However, since the first heating device and the cooling device are provided above the work space, the bending of the yarn due to the increase of the winding stand is small, the stress on the yarn is reduced, and the quality of the yarn is improved.

  Furthermore, it is preferable that the first heating device and the cooling device are arranged substantially linearly along the horizontal direction. According to this, the yarn path from the first feed roller to the cooling device becomes close to a straight line, and the bending of the yarn traveling along the yarn path from the first feed roller to the cooling device is further reduced. Accordingly, the stress on the yarn is further reduced, and the quality of the yarn is further improved.

  In addition, it is preferable that the first heating device includes a heater body that surrounds the traveling yarn in a non-contact manner, and a heater that heats the inside of the heater body. According to this, as compared with a heating device that heats the yarn by contacting the inner wall surface of the heater body, the yarn can be heated uniformly and quickly, and the length of the first heating device can be shortened. Further, the contact resistance acting on the yarn is reduced, and high-speed winding becomes possible.

  Further, the cooling device has an air intake duct having a slit formed therein, and the vicinity of the slit on the outside of the air intake duct is caused by an air flow when the suction air from the air intake duct flows into the air intake duct from the slit. It is preferred that the traveling yarn is cooled. According to this, compared with the cooling device which cools the yarn by bringing it into contact with a cooled cooling plate or the like, the yarn can be cooled uniformly and quickly, and the length of the cooling device can be shortened. Further, the contact resistance acting on the yarn is reduced, and high-speed winding becomes possible.

  Furthermore, it is preferable that an apron nip type second feed roller is disposed between the false twisting device and the second heating device. The second feed roller has a higher yarn feed speed than the first feed roller in order to stretch the yarn, and a large tension is generated in the yarn niped by the second feed roller. When the yarn having such a large tension is surely sent downstream by the second feed roller, the second feed roller has a large nip so that no slip occurs between the second feed roller and the yarn. Power is required. Therefore, a large nip force can be secured by using the apron nip method for the second feed roller.

  In addition, the first heating device, the cooling device, the false twisting device, and the feed roller located on the upstream side of the second heating device in the yarn traveling direction are arranged on two yarns traveling in parallel. Two feed rollers are provided corresponding to each of the two yarns, and one feed roller is located on the downstream side of the second heating device and the second heating device in the yarn traveling direction. The two yarns fed out from the two false twisting devices travel through one second heating device and are sent to the winding device by one feed roller located on the downstream side. It is preferred that According to this, the number of feed rollers on the downstream side in the yarn traveling direction than the second heating device and the second heating device can be reduced, and the configuration can be simplified.

  Since many packages are wound in parallel, many packages can be wound in a short time. In addition, the full package can be taken out in a vacant space opposite to the work space, and a space for storing the full package can be secured while securing the work space. Furthermore, even if the number of winding devices increases in the vertical direction and the height of the winding table increases, the first heating device and the cooling device do not overlap with the winding table in the vertical direction. Therefore, the height of the entire false twisting machine does not increase, the size of the room for housing the false twisting machine remains the same, and the temperature adjustment cost in the room does not increase. In addition, since the first heating device and the cooling device are provided above the work space, the bending of the yarn due to an increase in the winding stand is small, the stress on the yarn is reduced, and the quality of the yarn is improved.

It is a schematic plan view of the false twist processing machine concerning this embodiment. It is the schematic explaining the arrangement | sequence of each apparatus along a yarn path. It is a longitudinal cross-sectional view along the yarn traveling direction of the first heating device. It is a longitudinal cross-sectional view of the direction orthogonal to the yarn traveling direction of the cooling device. It is a longitudinal cross-sectional view of the direction orthogonal to the yarn traveling direction of the second heating device. It is a top view of the 2nd feed roller.

  Hereinafter, embodiments of the present invention will be described. In this embodiment, for example, a false twisting machine for manufacturing a processed yarn rich in elasticity by applying false twist to a thermoplastic synthetic fiber such as polyester or polyamide to give a crimp will be described.

  First, a schematic configuration of the false twisting machine will be described with reference to FIG. As shown in FIG. 1, the false twisting machine 1 has a main machine base 2 and two winding stands 3 extending in the vertical direction. The two take-up tables 3 are arranged opposite to the main machine base 2 with a work space 6 in a line-symmetric position with the main machine base 2 as an axis. On the side opposite to the work space 6 of the take-up stand 3, there is a space 7 in which the operator picks up a fully wound package P that has been taken up by a take-up device 15 provided later on the take-up stand 3. To do. Further, the false twisting machine 1 includes two yarn feeding creels 5 (yarn feeding portions) disposed opposite to the two winding bases 3 with the space 7 interposed therebetween, and each of the two yarn feeding creels 5 supplied from the yarn feeding creel 5. And a winding device 15 for winding the yarn Y.

  As shown in FIGS. 1 and 2, the first feed roller 20, the first heating device 11, and the cooling device are arranged on the yarn path from the yarn feeding creel 5 to the winding device 15 in order from the upstream side in the yarn traveling direction. 12, a false twisting device 13, a second feed roller 21, a second heating device 14, and a third feed roller 22 are arranged. The winding device 15 is arranged in four stages in the vertical direction. Note that a plurality of these devices are arranged side by side in the direction perpendicular to the plane of FIG.

  In other words, in this false twisting machine 1, each device along the yarn path from the yarn feeding creel 5 to the winding device 15 is arranged symmetrically about the main machine base 2 as shown in FIG. A plurality are arranged side by side in the direction perpendicular to the page.

  The first feed roller 20 is disposed at the upper end portion of the winding table 3. The first heating device 11 is disposed above the work space 6. The cooling device 12 is disposed closer to the main machine base 2 than the first heating device 11 above the work space 6. The false twisting device 13 is arranged on the upper part of the main machine base 2. The second feed roller 21 is disposed below the false twisting device 13 of the main machine base 2. The second heating device 14 is disposed below the second feed roller 21 of the main machine base. The first heating device 11 and the cooling device 12 are arranged substantially linearly along the horizontal direction above the work space 6, and the yarn path from the yarn feeding creel 5 to the winding device 15 is the work space 6. Is formed so as to surround. The 1st heating apparatus 11 and the cooling device 12 are connected to the support part 4 which connects the main machine base 2 and the two winding bases 3, and the position is being fixed.

  A work path 17 is disposed in the work space 6, and a thread hanging work carriage 18 travels in the direction perpendicular to the paper surface of FIG. An operator can get on the threading work carriage 18 and perform threading at a high position in the vicinity of the first heating device 11 and the cooling device 12 or perform maintenance.

  The first to third feed rollers 20 to 22 are rollers for feeding the yarn Y from the upstream side to the downstream side in the yarn traveling direction, and the yarn of the second feed roller 21 is faster than the yarn feed speed of the first feed roller 20. Each yarn feed speed is set so that the feed speed is increased. For this reason, the yarn Y is stretched between the first feed roller 20 and the second feed roller 21. Each yarn feed speed is set so that the yarn feed speed of the third feed roller 22 is slower than the yarn feed speed of the second feed roller 21. For this reason, the yarn Y is subjected to relaxation heat treatment between the second feed roller 21 and the third feed roller 22.

  Here, the operation of the false twisting machine 1 until the yarn fed from the yarn feeding creel 5 is taken up by the winding device 15 will be briefly described. The yarn Y drawn between the first feed roller 20 and the second feed roller 21 is twisted by the false twisting device 13. More specifically, the false twisting device 13 is a belt-type nip twister, and twists and feeds the yarn Y with the yarn Y traveling between a pair of belts crossing each other. The twist formed by the false twisting device 13 propagates to the first feed roller 20, and the yarn Y twisted while being stretched is heat-fixed by the first heating device 11 and then cooled by the cooling device 12. The The twisted and heat-fixed yarn Y is untwisted by the time it reaches the second feed roller 21 after passing through the false twisting device 13.

  The yarn Y thus stretched and false twisted is subjected to relaxation heat treatment by the second heating device 14 and wound around the paper tube by the winding device 15 to form a package P. The fully packaged package P is automatically removed from the winding device 15 and sequentially stored in a stocker described later that extends to the space 7 side opposite to the work space 6. Then, a new paper tube is automatically attached to the winding device 15, and the winding operation is continued without operator intervention.

  Next, the 1st heating apparatus 11 is demonstrated with reference to FIG. As shown in FIG. 3, the 1st heating apparatus 11 is using the heat processing apparatus of patent gazette 2856260, for example, and the heat insulating material 31 extended linearly along the horizontal direction (yarn running direction). A heat insulating cover 32 that covers the heat insulating material 31, and two sheathed heaters 35 and 36 and two temperature sensors 37 provided in the two heater bodies 33 and 34 formed of two cavities formed in the heat insulating material 31. 38. The temperature in the heater bodies 33 and 34 is set to a desired temperature by the two temperature sensors 37 and 38 according to the yarn feed speed, the thickness and type of the yarn, and the yarn Y traveling in the heater bodies 33 and 34 is set to a desired temperature. It is feedback controlled to be at the proper temperature possible.

  In the heater bodies 33 and 34, thread guides (not shown) made of ceramics, for example, are arranged at equal intervals along the yarn traveling direction so as to protrude from the inner wall surfaces of the heater bodies 33 and 34. The yarn Y traveling in the heater main bodies 33 and 34 is heated by the temperature in the heater main bodies 33 and 34 without contacting the inner wall surface of the heater main bodies 33 and 34 by being in contact with and guided by the yarn guide. It has a configuration.

  Further, the yarn Y traveling in the heater bodies 33 and 34 has an arc shape by being guided by the yarn guide, and can prevent vibration (ballooning) as compared with the case of traveling linearly. it can. Such a first heating device 11 can heat the yarn Y uniformly and faster by the air in the heater bodies 33 and 34 than the heating device that contacts the inner wall surfaces of the heater bodies 33 and 34 and heats the yarn Y. The length of the first heating device 11 in the yarn traveling direction can be shortened. Further, the contact resistance acting on the yarn Y is reduced, and high-speed winding becomes possible.

  Next, the cooling device 12 will be described with reference to FIG. As shown in FIG. 4, the cooling device 12 uses, for example, a cooling device described in JP-A-9-316740, and an intake duct 41 extending in a direction perpendicular to the paper surface of FIG. 1 perpendicular to the yarn traveling direction. have. An exhaust fan (not shown) is connected to the end of the intake duct 41 on one side in the extending direction, and the rotational speed of the driving motor is controlled by an inverter.

  Two slits 42 are formed below the intake duct 41 so as to be separated along the extending direction. Two guides 43 and 44 for restricting the flow of airflow to the intake duct 41 are provided outside the slit 42. The yarn Y travels between the two guides 43 and 44 in the vicinity of the slit 42 outside the intake duct 41. In the present embodiment, the two yarns Y adjacent in the direction perpendicular to the paper surface of FIG. 1 can be cooled by a single cooling device. In the two guides 43 and 44, contact bodies 45 and 46 are discretely arranged on opposite surfaces along the yarn traveling direction. The contact bodies 45 and 46 are arranged in a staggered manner as viewed from above, and the yarn Y traveling between the two guides 43 and 44 alternately contacts the contact bodies 45 and 46.

  In the cooling device 12, when the exhaust fan is driven, suction air from the intake duct 41 flows into the intake duct 41 from the slit 42. At this time, the yarn Y is cooled by the contact of the yarn Y with the contact bodies 45 and 46 cooled by the airflow flowing into the slit 42. Further, the yarn Y is directly cooled by the airflow flowing into the slit 42. Thus, since the yarn Y is cooled by the two cooling actions, the cooling effect is high, and the yarn Y can be quickly cooled to a desired temperature. Therefore, the length of the cooling device 12 in the yarn traveling direction can be shortened. Further, since the yarn Y traveling in the cooling device 12 is not always in contact with the contact bodies 45 and 46, but in contact with each other, the contact resistance is reduced, and high-speed winding is possible.

  As described above, the lengths of the first heating device 11 (1 m in the present embodiment) and the cooling device 12 (0.6 m in the present embodiment) in the yarn traveling direction are shortened. Two devices can be arranged almost linearly in the horizontal direction above the work space 6. If the first heating device 11 (conventionally 2 to 2.5 m) and the cooling device 12 (conventionally 1.5 m) are long, it is necessary to arrange these devices above the work space 6. The space 6 needs to be widened. If the work space 6 is widened, the false twisting machine 1 will be enlarged. Then, the size of the room that accommodates the false twisting machine 1 also increases, and the temperature adjustment cost of the room increases.

  Further, if the first heating device 11 and the cooling device 12 are arranged so as to protrude above the winding table 3 above the working space 6, the working space 6 does not need to be widened, but is provided on the winding table 3. In addition, when the yarn Y is fed from the first feed roller 20 to the first heating device 11, the bending of the yarn Y becomes large. When the bending of the yarn Y is large, the stress applied to the yarn Y is large and the quality of the yarn Y is degraded. Therefore, in the present embodiment, the lengths of the first heating device 11 and the cooling device 12 in the yarn traveling direction are shortened, so that these devices can be arranged above the work space 6 without increasing the work space 6. Can be arranged almost linearly along the horizontal direction. Therefore, there is no increase in the temperature adjustment cost in the room accompanying the increase in the room for housing the false twisting machine 1. Further, the bending of the yarn Y from the first feed roller 20 to the first heating device 11 can be reduced, and the quality of the yarn Y is improved.

  Next, the second heating device 14 will be described with reference to FIG. As shown in FIG. 5, the second heating device 14 is provided on the main machine base 2 along the vertical direction. In the second heating device 14, the heat medium 52 is filled between the two pipes 51 and 53 extending in the vertical direction, and two pipes 55 are inserted into the space 54 in the pipe 53. A thread Y is inserted into the pipe 55. When the heat medium 52 is heated, the second heating device 14 heats the air in the space 54 in the pipe 53, the air in the pipe 55, and the space in the pipe 55 by the heat of the heat medium 52. The yarn Y inserted through is heated. One second heating device 14 heats two yarns Y fed from two false twisting devices 13 adjacent to each other in the direction perpendicular to the paper surface of FIG. 1 via two second feed rollers 21.

  As shown in FIG. 2, each feed roller (not shown) including the third feed roller 22 on the downstream side of the second heating device 14 has two feed rollers fed from each second heating device 14. The yarn Y is fed downstream by one feed roller. That is, the number of the second heating device 14 and the third feed roller 22 is halved compared with the number of the first feed roller 20, the first heating device 11, the false twisting device 13, and the second feed roller 21. Yes. Further, as described above, the cooling device 12 also cools two adjacent yarns Y with respect to the direction perpendicular to the paper surface of FIG. 1 by the single cooling device 12, and similarly to the second heating device 14 and the third feed roller 22. It is half. Thereby, the structure of the false twisting machine 1 can be simplified and the cost can be reduced.

  Next, the winding device 15 will be described. As shown in FIG. 1, the winding device 15 includes a take-up winder 61 and a doffing device 62.

  The take-up winder 61 includes a cradle that holds the paper tube or package P being wound, a winding roller that makes frictional contact with the paper tube or package P, and rotates the traverse mechanism.

  The doffing device 62 includes a cradle operating mechanism that opens and closes and unfolds the cradle to detach the package from the take-up roller, and a yarn cutting mechanism that cuts the yarn connected to the package to be paid out. Air sucker for holding by suction, stocker for temporarily storing the delivered package P, paper tube holder for storing paper tubes, paper tube supply mechanism for supplying paper tubes to the cradle, and yarn for threading the paper tubes held by the cradle It consists of a hanging mechanism.

  When the timer count reaches a predetermined count, the winding device 15 configured by each mechanism automatically removes the fully wound package P from the cradle and discharges it to the rear stocker. Then, the paper tube is supplied from the paper tube holder to the cradle via the paper tube supply mechanism, and the paper tube held by the cradle is hooked by the yarn hooking mechanism to wind the paper tube. In other words, it is possible to automatically wind up all the paper tubes stored in the paper tube holder until the winding is completed without any operator intervention.

  Next, the second feed roller 21 will be described with reference to FIG. As shown in FIG. 6, the second feed roller 21 is an apron nip method, an endless belt 67 is wound around two driven rollers 65 and 66, and the driving roller 68 is in surface contact with the belt 67. Yes. The second feed roller 21 is configured such that when the driving roller 68 rotates, the belt 67 travels, and the driven rollers 65 and 66 rotate as the belt 67 travels. The yarn Y sent from the false twisting device 13 is nipped between the belt 67 and the driving roller 68 and sent to the second heating device 14 on the downstream side in the yarn traveling direction.

  Since the second feed roller 21 has a yarn feed speed faster than that of the first feed roller 20, a drawing force acts on the yarn Y nipped by the second feed roller 21, and a large tension is generated. When trying to send the yarn Y with such a large tension to the downstream side by the nip roller, a slip occurs between the nip roller and the yarn Y, and it becomes difficult to give the yarn Y a desired drawing force. End up. Therefore, in the present embodiment, the second feed roller 21 is an apron nip method, and the yarn Y is nipped at the large contact surface between the belt 67 and the driving roller 68, so that a large nip force can be secured, While applying a desired stretching force to the yarn Y, the yarn Y can be reliably sent downstream.

  According to the false twisting machine 1 of the present embodiment, the winding device 15 is arranged in four stages in the vertical direction, and the winding device 15 is wound in parallel as compared with the case where the winding device 15 having three or less stages is arranged. Since the number of packages P to be processed is large, winding can be performed on many packages P in a short time.

  Generally, when the winding device 15 is mounted on the winding table 3 in four stages in the vertical direction, it is difficult for the operator to replace the package P of the winding device 15 at a high position. End up. Therefore, by exchanging the package P, the work of replacing the package P of the winding device 15 located above when the winding device 15 is mounted on the winding table 3 in four stages in the vertical direction. Disadvantages that become difficult are eliminated.

  In addition, when the replacement of the package P is automated, the number of workers intervening is reduced and the number of workers can be reduced. On the other hand, when the number of workers is reduced, it is preferable to reduce the number of times the full package P is picked up. However, this requires a space for storing the full package P. Therefore, in the present embodiment, the full package P can be taken out into a vacant space (space 7) opposite to the work space 6, and when the full package P is taken out to the work space 6, the package P If the package P is not taken up, the problem that the working space 6 becomes narrow as the package P accumulates does not occur. Thus, many full-packages P can be stored in this vacant space, and the frequency of picking up full-packages P is reduced, so that work efficiency is improved.

  In addition, since the first heating device 11 and the cooling device 12 are provided above the work space 6, the first heating device 11 and the cooling device can be cooled even if the number of the winding devices 15 is increased in four stages in the vertical direction. Since the device 12 does not overlap the winding table 3 in the vertical direction, the positions of the first heating device 11 and the cooling device 12 are not increased. Therefore, the height of the false twisting machine 1 as a whole is not increased, the size of the room in which the false twisting machine 1 is accommodated is not changed, and the temperature adjustment cost in the room is not increased.

  If the winding devices 15 are arranged in three stages in the vertical direction, and these winding devices 15 are arranged in four rows per span in the direction perpendicular to the paper surface of FIG. A total of 24 packages P are wound up by the processing machine 1. Furthermore, if this false twisting machine 1 is arranged 10 spans in the direction perpendicular to the paper surface of FIG. 1, a total of 240 spindles of the package P are wound. One spindle refers to a unit composed of devices that wind up one yarn Y.

  On the other hand, in the present embodiment, the winding devices 15 are arranged in four stages in the vertical direction, and these winding devices 15 are arranged in four rows per one span in the vertical direction on the paper surface of FIG. It is possible to wind up a total of 32 packages P with one false twisting machine 1. If a plurality of false twisting machines 1 are provided to wind up the number of packages P close to the 240 weight package P described above, it is only necessary to arrange 7 to 8 spans in the direction perpendicular to the plane of FIG. Therefore, when compared with the same number of spindles, the number of false twisting machines 1 can be reduced, the room in which the false twisting machine 1 is accommodated can be reduced, and the temperature adjustment cost in the room can be reduced.

  Next, modified embodiments in which various modifications are made to the embodiment will be described. However, components having the same configuration as in the above embodiment are given the same reference numerals and description thereof is omitted as appropriate.

  In the present embodiment, the first heating device 11 and the cooling device 12 are provided substantially linearly along the horizontal direction above the work space 6, but vertically above the work space 6 and the take-up stand 3. You may provide along the direction containing a direction component. Further, the first heating device 11 and the cooling device 12 may be arranged so as to protrude from above the work space 6 and above the take-up stand 3 or the main machine stand 2. An example of such a case is when the yarn Y is very thick and the first heating device 11 needs to be very long to heat the yarn Y to a desired temperature. The same applies to the cooling device 12.

  Further, the false twisting device 13 is not limited to a belt-type nip twister, and may be any type of device as long as false twisting can be performed, for example, a friction disk twister.

  Further, the first heating device 11 may not have a configuration in which the yarn Y contacts the inner wall surfaces of the heater bodies 33 and 34 as described above, but may have a configuration in which the yarn Y contacts the inner wall surface. A configuration like the apparatus 14 may be used.

  In addition, the cooling device 12 is not limited to the configuration in which the yarn Y is cooled by the airflow as described above, but may be configured to cool the yarn Y by contacting a contact object such as a cooling plate.

  Further, the second feed roller 21 is not limited to the apron nip method, and may be any method as long as a large nip force can be secured. You may increase your power.
