Description of the invention (2) In the above device, the movable segment is moved and operated 'while the nozzle surface is arranged obliquely with respect to the horizontal-inclination angle of the movable segment. Because the moving piece = the track = the present bad yarn 'is on the inclined nozzle surface: it is pressed to make contact with the nozzle surface. In this regard, the eighth = first being "pressurized repeatedly to make contact with the surface of the nozzle and cut; m 'it may be bent, deformed or excessively worn. Now = m yarn: the cutter should not be in close contact with the nozzle surface or moved in a tilted position to reduce the operating effect. Second, another problem with the arrangement is that the discharge groove is horizontal and fixed. Broadcasting = the angle of the nozzle surface is unexpectedly changed to another angle. The position of the groove cannot be adjusted. The Moon-Ha vertical device (disclosed in the aforementioned Japanese patent) includes at least a row of grooves to controllably feed the melt lines emerging from the nozzle. The drain slot includes an upper end which selectively guides the yarn to two "one yarn feeding channels extending to the slot and a multi-line falling channel extending on the slot side. The device also has a collector, It is arranged on the yarn drop channel on the groove side, and collects the yarn falling from the nozzle. The drain groove can rotate around a rotating shaft so the groove can be moved between the operating and non-operating positions. In its operating position, the groove It is placed on the yarn drop channel, so it catches the yarn emerging from the nozzle. When the slot is in its inoperative position, it is separated from the yarn drop channel, so it cannot catch the yarn and allow the yarn on the slot side to pass freely .Operating position in the drainage tank

Cooling device 10 on each side. The driving section 40 also supports the movable section 50 which moves the surface 20 in a straight line. It can be supported parallel to the nozzle by the two driving portions 40, which is the first of the beginning, that is, the movable portion 50 is used at both ends and is used to cut off the yarn that emerges from the nozzle 22 and the bad yarn. The center of the rear part of the cold section device 10 is turned to a drum joint 60, so the device 10 can be rotated 20 relative to the nozzle surface. Therefore, it may change the position of the device 10 relative to the nozzle surface 20. 7 Each driving part 40 includes a rodless cylinder 42 which is placed outside each rotatable panel 30 and moves linearly during the operation of the device. The guide shaft 44 guides the driving portion 40 in the linear movement of the rodless cylinder 42. Both the cylinder 42 and the guide shaft 44 are covered and supported by a bracket 46. The driving portion 40 is connected to the movable portion 50 via a connecting portion 48 provided at the upper end of the bracket 46. The perforated cooling pipe 54 is installed inside the movable portion 50 and cools the front guide panel 52 of the movable portion 50. The joint 60 includes a rotation shaft 62 mounted to a bracket 80. In order to adjust the angular position of the rotation shaft 62 and the adjustment position supporting the rotation shaft 62, the hinge 60 also includes an angle control device 64. The yarn channel defined by the cooling tank 12 and the side panels 14 and with the cooling tube 16 extending therein is covered by a cover plate 70, so that the cooling liquid is prevented from flowing out of the tube 16 and spilled to the outside of the yarn channel. It is described below. When the molten resin yarn emerges from the nozzle 22, the starting yarn is generally poor in quality due to a difference in heating temperature or poor color matching, as is conventionally described. because

C: \ PrograniFiles \ Patent \ 5146-2153-P.ptd page 9 403698 V. Description of the invention (7) Therefore, the first defective yarn among the yarns appearing from the nozzle 22 must be removed. The device of the present invention The bad yarns are automatically and effectively cut, and the continuous yarns or good yarns are sequentially fed smoothly to the cooling tank 12 having the cooling liquid flowing continuously from the cooling pipe 16. A plurality of longitudinal grooves are formed in the grooves 12 and lead a good yarn to the lower end of the grooves 12. When a good yarn passes through the groove 12, the cooling pipe 16 sprays a cooling liquid on the yarn to cool the yarn. The cooled yarns are sequentially fed to a yarn chainer that performs the yarn chaining process. In the apparatus of the present invention, the first defective yarns appearing from the nozzle 22 of the nozzle surface 20 are cut and collected separately. After cutting the bad yarn, the device feeds the good yarn appearing from the nozzle 22 to the yarn coarser after the bad yarn. When a good yarn emerges from the nozzle 22, the rodless cylinders 42 of the two driving portions 40 are activated manually or automatically, so that the inclination of each cylinder 42 is equal to the nozzle surface 20. Therefore, the two rodless cylinders 42 are arranged parallel to the nozzle surface 20. In the above state, the movable portion 50 connected to the rodless cylinder 42 moves linearly with respect to the movement of the cylinder 42. In this case, the movable portion 50 having the front guide panel 52 moves parallel to the nozzle surface 20 while cutting the first defective yarn appearing from the nozzle 22 at the same time. In this case, the yarn cutting operation is performed by a yarn cutting device mounted to the movable portion 50, which will be described below. After the first defective yarn was completely cut by the moving part 50, the good ^ began to emerge from the nozzle 22%. In this case, the moving part 5Q is placed on the yarn path from the nozzle 22, so the good yarn is captured by the leading bow J face of the moving part 5 () and is guided in the cooling tank 12 in order The bottom is guided to the rough. The front guide panel 52 is tilted downward at an inclination angle, so the panel 52 and the following are from I ^ ΗΊΗΗΓ C: \ Program Files \ Patent \ 5146-2153-P. Ptd ^ 10 ^ ------- 403696 V. Invention Explanation (8)-The coolant of the taxi tube 16 guides the good yarn smoothly. After all the good yarn has been fed to the roughener, the rodless cylinder 42 returns to its starting position, thus causing the inclined moving part 50 to move upward and the upper end of the moving part 50 continuously parallel to the nozzle surface 20. Therefore, the device enters the standby state and waits for the next yarn feeding process. In the above-mentioned operation of the apparatus, the 'pressurized coolant is sprayed from the perforations 56 of the cooling pipe 54 extending in the movable portion 50 to the back of the front guide panel 52, so the yarn passing through the guide panel 52 is cooled first. The yarns that are cooled first pass through the cooling tank 12 'in sequence and therefore are finally cooled while being fed to the roughener. The inclination of the mouth surface 20 may be unexpectedly changed during the operation of the device. In the case of 14, the rodless cylinder 42 is not parallel to the nozzle surface 20, so it must adjust the position of the cylinder 42 relative to the nozzle surface 20. To achieve the above-mentioned purpose, the lock bolts 34 received in the slits 36 of each rotatable panel 30 are loosened before removing the cylinder 42 to a position parallel to the nozzle surface 20, and are removed from each side panel 14. Therefore, it is possible to keep the rodless cylinder 42 parallel to the nozzle surface 20. That is, each of the rotatable panels 30 having the rodless cylinder 42 and the guide shaft 44 is rotatable about the rotation shaft 32. Figures 3a and 3b show the yarn feeding device of the present invention. The cooling load 10 is placed horizontally with respect to the nozzle surface 20. The fourth circle shows that the yarn feeding device with the cooling device 10 is placed vertically with respect to the nozzle surface 22. As shown in the figure, the position of the cooling device 10 relative to the nozzle surface 20 is selectively changed between horizontal and vertical positions by the processing and mechanical conditions of yarn feed processing, so the device type can be changed between horizontal and vertical types. In order to change the device type to a horizontal type as shown in Figures 3a and 3b, the nozzle surface is 20mm mm C: \ PrograniFiles \ Patent \ 5146-2153-P. Ptd page 11 403696 V.
