ABSTRACT:
Method and apparatus for stripping the insulation off wire being drawn from a wire supply along a feed path by means of the coil winding machine. The wire is drawn through a wire stripper device, which is preferably of the type which comprises a plurality of rotating blades that rotate about and engage the surface of the wire so as to cut the insulation therefrom. The stripper device is actuated by the turns counter of the winding machine at a very accurately predetermined point in the winding cycle so that the segment of wire which is stripped will be positioned within the wire cutter following completion of the coil winding cycle, at which point the wire is severed. This produces stripped wire ends for one of the leads of the coil just wound and for one of the leads of the coil which is to be next wound. The wire can be pulled through the stripper by the coil winding machine. Alternatively, the winding head or spindle of the winding machine is stopped during stripping and the wire is pulled through the stripper device either manually or by a mechanical puller or the stripper device is moved along the wire.
