Abstract
A method and mechanism for repairing warp thread breaks in a weaving loom in which a broken warp thread is detected by a fallen drop wire of a warp stop motion device, the method comprising: upon the falling of a drop wire, taking a new warp thread from a supply of warp thread separate from the loom supply of warp thread, and moving the new warp thread to a position between the warp stop motion device and the harness of the loom by a rethreading mechanism; raising the fallen drop wire and threading a first end of the new warp thread through the raised drop wire by the rethreading mechanism; and threading a second end of the new warp thread through a heddle of the harness corresponding to the broken warp thread.
