Abstract

PURPOSE: To reduce a malfunction by judging the success or failure of weft treatment from the detected result of the existence or absence of weft on a weft take-off route when the operation of a fixed number of steps of a stepping motor to take off a mistaken yarn in warp opening is completed. CONSTITUTION: A hollowing weft Y1 connected to a mistaken yarn Y' is drawn out through a weft guide duct 16 to a suction duct 21 by a jet air flow from a spray pipe 17a of a blow nozzle by weft take-off rollers 24 and 28. The existence or absence of a weft is detected by a weft detector 31 after operation of a fixed number of steps of a stepping motor 23 is completed. In the case of detection of absence of weft, the weft treatment is judged as a failure.
