四级原题摘要：Apparatus and methods involving lacing or tying cord about end turn portions of coils that project beyond faces of dynamoelectric machine magnetic cores. Method involves pulling and holding final cord gments; and subquently releasing such gments. In apparatus, stator core having coils therein is placed at tying station and supported while the core and tying units are periodically relatively indexed. Loops of cord are placed about winding portions, for example in the formation of stitches. As the last loop (e.g., stitch) in a tying cycle is commenced, cord pulling member and core are moved relative to each other so that the cord pulling member is located to receive a final cord gment. Alternatively, cord pulling member moves after full development of final cord gment. A portion of final cord gment is grasped in a cord receiving region of cord pulling member. Cord clamping member engages and tightly holds the cord; cord pulling member retracts; and final cord gment is pulled taut and vered. The leading or advancing end of the cord pulling member may be of a blunt or pointed configuration. When a core is to be laced or tied, an end of cord is held in the cord puller and at least part of one or more loops (e.g., stitches) are made on the wound stator asmbly. At a predetermined time or after a predetermined number of stitches (or portions thereof)

have been made, the end of cord is relead. Such relea is effected before excessive tension is applied to the core so as to reduce, if not eliminate, cord fraying and cord debris build-up in and around the cord puller. This also prevents malfunctions that might occur as a result of excessive tension on a cord end during indexing of a core being laced.
