Claims

[Scope of utility model registration request]

The cutting action of the weaving weft cutting device, which cuts and separates the weft threads with normal weft insertion from the main nozzle for weft insertion every time the weft is beat, is disabled when the machine is stopped in the event of abnormal weft insertion, and the cutting action of the weft threads from the main nozzle for weft insertion is disabled. In the defective weft processing device, the injected weft is delivered to a weft pulling means, and the weft thread connected to the defective weft on the front of the woven fabric is pulled out from inside the warp opening to the side by the weft pulling means. Alternatively, a weft separating means equipped with a weft separating hook capable of reciprocating between a standby position outside the reed swinging area on the fabric front side and a working position inside the warp shedding is disposed above to separate the warp groups from either the upper or lower side. The distal end of the weft separating hook that can enter into the warp opening is formed into a bifurcated part consisting of an upper jaw part and a lower jaw part,
The angle of inclination of the group of warp yarns, which are pulled apart by the weft separating hook, with respect to the woven fabric line is made smaller than the angle of inclination of the inner edge of the jaw section, which comes into contact with the group of warp yarns later, among the opposing inner edges of both the upper and lower jaw sections, with respect to the woven fabric line. A defective weft processing device for a loom that sets a magnitude relationship between both inclination angles.
