Detecting and removing faulty weft in a jet loom
An apparatus and its method of operation whereby when a jet loom is deenergized upon occurrence of abnormality in the insertion of a weft, the cutting operation of an inserted weft cutting device is prevented. As a result, a weft succeeding to the misinserted one is forcibly introduced into a weft introducing duct under blowing action of a blow nozzle oriented in a direction intersecting the weft insertion direction to be transferred to a pair of gripper rollers. The weft is separated by cutting from a weft inserting main nozzle by a second weft cutter device. Subsequently, the misinserted weft is withdrawn in the direction away from a cloth fell toward a reed with inclination relative to the weft insertion path within a region where the weft remains out of contact with warps.
