Abstract

A method and apparatus for separating a broken warp thread at the warp stop motion from the warp sheet on a weaving machine in which the warp stop motion includes several rows of drop wires, the method including the step of extracting a loop in the broken warp thread caused by a sag as a result of the corresponding drop wire falling away from the fallen drop wire. The apparatus includes a series of suction or blower nozzles or grippers which are sequentially activated to pass the loop between the adjacent nozzles or grippers toward the side of the warp sheet.
