Claims (1)

[Scope of Claim for Utility Model Registration] (1) The tip of a mis-thread suction pipe is opened at the outlet end of the main jet nozzle that injects the weft into the shed, and the exit of the suction pipe and the mis-thread suction nozzle are connected. A pair of pull-out rollers are disposed in the middle so that they can be moved toward and away from each other, a switch for detecting a mis-thread is provided on the supporting member of one of the pressure rollers, and a detection lever for operating the switch is placed facing the mis-thread pull-out passage. Mistake thread removal device for fluid jet looms. (2) The scope of the utility model registration claim, in which the detection lever is positioned forward of the tip of the pressure roller that is moved laterally to apply pressure to the take-up roller when the detection lever is placed on the pull-out roller side and faces the mis-thread pull-out passage. The mis-thread removing device according to item 1. (3) The mis-thread removing device according to claim 1, wherein the detection lever is a photoelectric device that detects the presence or absence of mis-thread by the light-shielding effect of a light-emitting/light-receiving device.
