Abstract (en)

To prevent a defective weft at the fabric side from being cut, when the defective weft is to be disposed, and to prevent the weft from coming out of the main nozzle and the reserved weft to be measured from being disturbed. In control method and apparatus for disposing a defective weft in a shuttleless loom, when failure in weft insertion is detected by a weft detecting device (6) which is arranged upon the opposite end of weft insertion, a blow nozzle (71) injects compressed air into a weft guiding duct (72), and guides the defective weft into the duct. Then a nip roller (8) holds the defective, and a cutter (9) cuts the weft. After this, the nip roller (8) pulls out and removes the weft. After the nip roller (8) holds the defective weft, it rotates round preliminarily in the direction according to the kinds of yarns, and controls the condition of the defective weft. Then the cutter (9) cuts the controlled weft. <IMAGE>
