されて織布に織りこまれる。(Conventional technology) Shuttleless looms such as jet looms can be expected to have much higher productivity than frame looms, and there has been a noticeable trend in the adoption of shuttleless looms in recent years, but the rate of weft insertion errors has decreased. It is a well-known fact that the cost of looms is higher than that of frame looms. In the event of a weft insertion error, the machine is stopped based on the weft insertion error detection signal from the weft detector, but in high-speed looms such as shuttleless looms, the machine is rotated more than once in order to prevent damage to each part. Since the machine is stopped after inertial operation, the weft threads that were inserted incorrectly (hereinafter referred to as "missed threads") are beaten just before the machine stops and are woven into the woven fabric.

After moving from the woven fabric to a predetermined mis-thread processing position, the finger is slid on the woven fabric and enters the warp opening while rubbing the front of the fabric from outside the warp opening, and removes the mis-thread from the woven fabric into the warp opening. It is designed to separate into

より吸引除去される。A portion of the misplaced yarns that have been pulled out of the warp shedding are held under pressure between a pair of pull-out rollers, and by driving both of the pull-out rollers, all of the miss yarns are pulled out from inside the warp shedding. The erroneous yarn pulled out in this way is removed by suction by the suction means.

てしまい、織布品質低下に繋がる。(Problems to be Solved by the Invention) In a conventional device such as that disclosed in Japanese Patent Application Laid-Open No. 58-220856, the first requirement is that the fingers catch the misplaced threads driven into the woven fabric and remove the misfied threads from the woven fabric. The goal is to ensure separation of the two. The fingers are designed with a nearly elliptical trajectory to catch the wrong thread.
Separating a single misplaced thread from the fabric requires extremely delicate movements of the fingers. However, even when the warp threads are in the maximum opening state, the grasping state of the miss threads by the warp threads is not sufficiently released. Even though the approximately elliptical trajectory is created by the complicated configuration of circular motion, it is difficult to reliably avoid a situation in which the thread fails to catch a misplaced thread. If the separation of misplaced yarns fails, the misplaced yarns will be woven into the woven fabric, leading to a decrease in the quality of the woven fabric.

にも、フィンガーによる前記分離部位以外では経糸によ
る把持作用を依然として受けていることから、経糸開口
内から経糸開口外へミス糸を引き出す際には相応の引き
出し抵抗が生ずる。Even if the fingers succeed in separating the misplaced threads from the weaving front, the gripping action of the warp threads is still applied to areas other than the separation site by the fingers, so when pulling out the misplaced threads from the inside of the warp shedding to the outside of the warp shedding, A corresponding withdrawal resistance occurs.
そのため、ミス糸の引き出し途中において前記引き出し
抵抗に起因してミス糸切断が生ずるおそれが多分にある
。これもまた織布内へのミス糸織り込みに繋がり、織布
の品質低下をもたらす。Therefore, there is a high possibility that the erroneous yarn will be cut due to the pull-out resistance while the erroneous yarn is being pulled out. This also leads to mis-weaving of threads into the woven fabric, resulting in a decrease in the quality of the woven fabric.
特開昭５９−２２０８５６号公報の従来装置においても
引き出し抵抗に起因する引き出し途中のミス糸切断発生
のおそれは同様に存在する。In the conventional device disclosed in Japanese Patent Application Laid-Open No. 59-220856, there is a similar possibility that the thread will be cut by mistake during drawing due to the drawing resistance.

合には緯糸引き出し処理失敗と判定するようにした。Structure of the Invention (Means for Solving Problems) Therefore, in the present invention, the warp threads are formed in an open state, and the weft threads woven into the woven fabric immediately before the machine stops are released. The weft is pressed and held between a pair of movable rotating bodies that are disposed so as to be separable from each other across a pull-out path for the weft to be pulled out from the warp opening, and the weft rotates as the weft is pulled out by a weft pull-out device. The amount of rotation of the contact rotary body is detected, and if the detected amount of rotation is within a preset rotation amount range, it is determined that the weft pulling process is successful, and the detected amount of rotation is within the set range. If there is no weft, it is determined that the weft drawing process has failed.

It is pulled out from within the opening. As the weft is pulled out, the pair of contact rotors that press and hold the weft rotate accordingly, and the amount of rotation of the contact rotor is detected by the rotation amount detection means. When the weft thread is drawn out from inside the warp shedding normally, the detected rotation amount falls within a preset range, and it is determined that the weft thread drawing process is successful, and machine restart is selected. .
