Abstract
A weft treatment system and method for removing a mispicked weft yarn from a weft path of a fluid jet loom of the type wherein a weft yarn from a weft supply member is introduced through a weft storage unit to a weft inserting nozzle to be picked. With this system and method, a mispicked weft yarn is detected when mispick occurs. Then, the operation of a cutter and weaving operation of the loom are stopped. Subsequently, the loom is reversely run to expose the mispicked weft yarn at the cloth fell of a woven fabric. More specifically, the weft winding arm is reversely rotated around the storage drum to unwind the weft yarn on the drum. The thus exposed mispicked weft yarn is drawn through the weft storage unit by a weft traction device disposed between the weft supply member and the weft storage unit.
