Abstract
A stator coil finish wire is wedged between the wound coil from which it extends and the stator core at a stator winding station. To accomplish this, a loop is formed in the finish lead and trapped between cooperating surfaces to frictionally resist the wire loop being pulled out by the wire gripper of a lead pull assembly. The wire gripper moves in directions to remove the loop and to wedge the stretch of the lead wire extending through the stator core between the coil and the core. This procedure is advantageously used when winding stators which do not have terminal boards.
