KNOT TYING APPARATUS AND METHOD FOR STATOR LACING MACHINE An apparatus and method for anchoring the starting end of the lacing cord and knoting the finishing end following lacing of the end turns of a dynamoelectric machine stator winding using the lacing machine and method which laces the cord about the end turns in a stitch pattern having double looped stitch intervals with a loop connecting each successive double looped stitch, such as that described and illustrated in U.S. Patent No. 3,659,337. The starting end of the lacing cord is clamped at a point spaced from the dispensing end of the cord feeding tube in a direction opposite the direction of indexing the stator core member during the lacing operation. At the completion of the formation of the first double looped stitch during which the starting end is laced under a part of the stitch and thus anchored, the stator is indexed with the starting end being pulled through the clamp under tension and the end turn lacing operation proceeds in the normal manner around the stator with the starting end being laced under and anchored by the double loop stitches. At the conclusion of the normal lacing operation, a final loop of the lacing cord is pulled through the last one of the connecting loops, the section of the cord which extends between the dispensing end of the feeding tube and the radially inner side of the end turns is cut thereby forming a finishing end of the cord and a new starting end, and the finishing end is pulled through the last connecting loop to form a knot, the new starting end being again clamped preparatory to a new lacing operation. |
