Abstract

PURPOSE: To provide the subject device for surely detecting the presence or absence of a weft by gripping the weft forcefully introduced into a sucking duct accompanying a weft insertion mistake with a compressing contact of a driving roller and a driven roller, and also rotating and sweeping a rotary detecting arm across a weft drawing passage. CONSTITUTION: This inferior weft treating device in a loom is provided by forcefully introducing a weft following after the mistaken yarn Y' into a sucking duct 21 through a weft introducing duct 16 by a compressed air flow of a blow nozzle under a dysfunction of a weft cutting device upon generating a weft insertion mistake and gripping the weft with a compressing contact between a downward moving driven roller 28 and a driving roller 24. Accompanying the downward movement of the driven roller 28, a supporting base frame 30 rotates centering around a supporting shaft 29, and a rotary detecting arm 31a rotates and sweeps across a taking up passage of the mistaken yarn Y'. Since the rotary detecting arm 31a relatively rotates to a main body of a weft detecting device 31, it is possible to detect the presence or absence of the weft surely.
