ABSTRACT:
A device for mending and trimming broken warp yarn includes a yarn holder mounted on a moving member for holding a free end of a mending yarn tied to a broken warp yarn. When a warp yarn is broken during the operation of the loom, one end of a mending yarn and the broken end of the broken warp yarn extending from the warp beam are tied together, and the other end of the mending yarn is passed through a corresponding heddle and a corresponding gap between the dents of a reed, and then the loom is restarted. A signaling device generates a signal after detecting the arrival of the free end of the mending yarn which was not woven into the cloth after the loom was restarted. The free end of the mending yarn is cut off automatically from the woven cloth by a cutter in accordance with the signal from the signaling device while the loom is in operation. A controller is connected to and controls all of the elements of the mending and trimming device.
