取ることによってたて糸開口中から除去している。When a weft insertion failure occurs on a water jet loom,
The control device of the loom operates a weft insertion prevention member, such as a clamper on the upstream side of the weft insertion nozzle or a locking bottle on the side of the drum second length storage device, to prevent the next weft insertion. Then, the cutting operation of the yarn feeding cutter is prohibited, and after the loom is stopped, the 7/& loom is turned in the reverse direction and the defective yarn is taken out. Next, the control device for removing the defective yarn unwinds the weft yarn using the weft insertion prevention member, captures the defective yarn that continues from the weft insertion nozzle to the woven fabric, and the unraveled weft yarn with the defective yarn removal device, and winds the weft yarn. It is removed from the warp opening by removing it.

そのよこ糸をよこ入れノズルの先端側近くで確実に捕捉
できなくなる。In the process in which the defective yarn removal device captures the unraveled weft yarn and the defective yarns connected to it between the weft insertion nozzle and the weft insertion side weave end of the woven fabric, the weft insertion nozzle and the weft insertion side weave edge of the woven fabric Since the weft yarn after unwinding becomes slack between the weft yarn and the weft yarn and comes off the extension line of the weft insertion nozzle, the defective yarn removing device cannot reliably catch the weft yarn near the tip of the weft insertion nozzle.
このよこ糸のたるみは、水噴射式織機に固有な現象であ
り、その発生原因は、下記の理由による。This slackness of the weft thread is a phenomenon unique to water jet looms, and the cause of its occurrence is as follows.
（１）よこ入れノズルが機台に固定されているため、筬
打ち時によこ入れノズルとよこ入れ側の織布端との間で
筬の一部によってよこ糸が引き伸ばされ、筬が後退した
ときに、よこ入れノズルとよこ入れ側の織布端との間で
その引き伸ばされたよこ糸が自由になって下方に垂れ下
がり、たるみが発生する。(1) Since the weft insertion nozzle is fixed to the machine base, the weft thread is stretched by a part of the reed between the weft insertion nozzle and the end of the fabric on the weft insertion side during reed beating, and when the reed retreats, The stretched weft becomes free between the weft insertion nozzle and the end of the fabric on the weft insertion side and hangs downward, causing slack.
（２） よこ入れ不良発生後、織機の慣性回転中によ
こ入れノズルから水が噴射され、この水がよこ入れノズ
ルと織布の織り端につながるよこ糸を引き出し方向に牽
引するため、その部分でのたるみが助長される。(2) After a weft insertion failure occurs, water is jetted from the weft insertion nozzle during the inertial rotation of the loom, and this water pulls the weft thread connected to the weft insertion nozzle and the woven end of the fabric in the unwinding direction, resulting in sagging is promoted.
（３）上記（１） ｆ２）の後、よこ入れ阻止部材とし

ズルとの間でよこ糸を係止するものが存在しなくなるた
め、よこ糸貯留装置からよこ入れノズルに連なるよこ糸
が自由な状態となって、張力が解放されることとなる。(3) After (1) f2) above, when the clamper or locking pin as a weft insertion prevention member unwinds the defective yarn before the defective yarn removal device operates, the weft yarn storage device and the weft insertion nozzle Since there is no longer anything to hold the weft yarn, the weft yarn connected from the weft storage device to the weft insertion nozzle becomes free, and the tension is released.
この結果、水を含んでよこ糸が重くなり、その重みによ
りよこ糸貯留装置に巻かれたよこ糸が解舒され、よこ入
れノズルの先端部より繰り出されて、よこ入れノズルか
らよこ入れ側の織布の織り端に連なるよこ糸に大きなた
るみが発生する。As a result, the weft yarn becomes heavy due to water content, and the weft yarn wound around the weft yarn storage device is unwound due to the weight and is unwound from the tip of the weft insertion nozzle. A large amount of slack occurs in the weft threads connected to the weaving ends.
このような主として３つの原因によって、よこ入れノズ
ルと織布のよこ入れ側織り端との間で、よこ糸がたるむ
ため、不良糸除去装置がよこ入れノズルの前でよこ糸を
捕捉しようとしても、捕捉。Due to these three main causes, the weft yarn becomes slack between the weft insertion nozzle and the weft insertion side weave end of the woven fabric, so even if the defective yarn removal device tries to capture the weft yarn in front of the weft insertion nozzle, it cannot be caught. .
できなくなる。become unable.
