A method of removing a mispicked weft yarn when a mispick occurs in a loom. The operation of the loom in a state where the mispicked weft yarn is connected to weft inserting means after the mispicked weft yarn is beaten up by a reed. The mispicked weft yarn is exposed at the cloth fell of a woven cloth. A weft yarn connected to the mispicked weft yarn is inserted from a weft picking side to a counter-weft picking side of the loom. The inserted weft yarn is drawn together with the mispicked weft yarn to the counter-weft picking side, thereby effectively peeling off the mispicked weft yarn from the cloth fell.

Mispicked weft yarn removing method and system therefor

A weft yarn end treating device for a shuttleless loom comprises a conveyer for conveying the end portion of a weft yarn picked into the shed of warp yarns when the end portion is held to contact with the conveyer, a holder for holding the end portion to contact with the conveyer, and a thrusting member for thrusting the end portion into a location at which the end portion begins to be held to contact with the conveyer, so that any binding yarns for catching and drawing the end portion of the picked weft yarn out of the shuttleless loom can be omitted to solve the problems raised in prior art.

Weft yarn end treating device for shuttleless loom

Catch yarns are drawn between a pair of rotatable members which are mounted to be movable toward and away from another and yieldably urged to come together. Detecting means detects the relative movement between the pair of rotatable members and produce an alarm-signal when the relative movement of one rotatable member away from another reaches a predetermined increased value. The catch yarns in tensioned state are further utilized to hold the detecting means at a rest position thereof. The detecting means also produces an alarm-signal upon the breakage of the catch yarns.
