Abstract
An auxiliary member is provided with gripping means for temporarily securing the leads of wire coils wound around the poles of a stator. When the stator reaches the winding station of the manufacturing process, both the stator and the auxiliary member can be transferred to the winding machine, where the leads of the stator coils are gripped by the gripping means. When winding has been completed, the stator and the auxiliary member are transferred to a terminating station where the coil leads are finally anchored to the terminal receptacles of the stator.

Apparatus for temporarily securing wire leads while processing an annular stator having at least one pole on which a coil of wire having at least a start lead and a finish lead is wound as a plurality of turns around the pole, the apparatus comprising:
- an annular auxiliary member removably engageable with an axial end of an outside surface of the stator, the member extending radially from the center of the stator and annularly around the stator at an axial location between the extreme axial ends of at least some of the turns of the coil, the member having a protuberance for engaging the axial end of the stator body, all portions of the auxiliary member being radially outside of all portions of the coil other than the start lead and the finish lead after the coil has been wound on the stator so that the coil does not prevent the entire auxiliary member from being removed from the stator as an annulus;
- and
- gripping means attached to the member for securing the wire leads during processing.
Apparatus for temporarily securing wire leads while processing an annular stator having at least one pole on which a coil of wire having at least a start lead and a finish lead is wound as a plurality of turns around the pole, the apparatus comprising:
- an auxiliary member substantially in the shape of a ring adapted to be placed substantially concentrically around the outer periphery of the stator at an axial location between the extreme axial ends of at least some of the turns of the coil and having an aperture, the aperture capable of being fitted around a support post at varying heights, all portions of the auxiliary member being radially outside of all portions of the coil other than the start lead and the finish lead after the coil has been wound on the stator so that the coil does not prevent the entire auxiliary member from being removed from the stator as a ring;
- and
- gripping means attached to the member for securing the wire leads during processing.
A method of processing a stator comprising the steps of:
- providing a hollow annular stator body having a plurality of projecting poles;

- temporarily securing at least one of the leads of the wire in the gripping means;
- moving the stator with the auxiliary member still mounted adjacent the end of the stator body to a terminating station;
- and
- transferring the at least one lead from the gripping means to a terminal mounted on the stator and attaching the at least one lead to the terminal so that the auxiliary member can be removed as an annulus from adjacent the end of the stator body.
A method of processing a stator comprising the steps of:
