  • Patent number: 4781221
    Abstract: 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.
