Abstract
A device for removing a broken warp thread from a warp stop motion includes a plurality of extraction elements that may include nozzles, hooks, grippers and the like that lift a slack loop of broken warp thread at a fallen drop wire associated with the broken warp thread and move the loop to a position outside the stop motion by passing the loop sequentially from one nozzle, etc. to the next in a single direction until the loop is outside the stop motion, where it can be gripped by a thread holder for further manipulation.
