Abstract
When a stator start wire is held outwardly away from a stator pole piece as a stator coil is being wound, the segment of wire, termed the first end turn herein, extending from the outwardly-placed start wire across the front end face of a stator being wound may interfere with the proper formation of the coil. Such interference is reduced or eliminated by extending the first end turn over a movable slack wire forming blade. When the slack wire forming blade is initially engaged with the first end turn, it pivots with the front placing blade to move the start wire away from the pole piece and increase the length of the first end turn. After the coil is partially wound, the slack wire forming blade is moved away from engagement with the first end turn so that the first end turn becomes slack and, therefore, does not interfere with the completion of the winding or the coil.
