摘要： 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.

摘要： A weft threading system for threading a weft yarn prior to restart of weaving operations of a fluid jet loom. The weft threading system is comprised of a weft winding arm forming part of a weft storage unit, arranged to wind the weft yarn on a drum under relative rotation between the weft winding arm and the drum. The weft winding arm is pipe-shaped so that an air jet is passed therethrough and ejected from its tip end section. The tip end section of the weft winding arm is bent so that the air jet ejected therefrom is directed to a weft guide disposed separate from the weft storage unit and on the upstream side of a weft inserting or main nozzle. The weft guide ejects an air jet in order to suck the weft yarn and project it therefrom, so that the weft yarn from the weft winding arm is automatically passed through the weft guide into the weft inserting nozzle.
