Abstract (en)

An abnormality detecting apparatus capable of detecting delamination of a surface layer of a rapier band of a weft inserting apparatus for a rapier loom. A pair of position regulating rollers (17; 18) are rotatably supported on a supporting plate (16). The position regulating rollers (17; 18) serve for regulating the position of the rapier band (12) relative to the circumferential surface of a rapier wheel (13), respectively. A pair of limit switches (19; 20) are disposed on the supporting plate (16) at a position corresponding to a wrapping range (E) over which the rapier band is wound around the rapier wheel. Probe rollers (192) of the limit switches are disposed closely to the rapier band (12). Detection ranges of the limit switches (19; 20) are defined in close proximity to a running path of the rapier band (12) within the wrapping range (E). <IMAGE>
