Apparatus for manufacturing wound stators

Claim 1

Apparatus for winding coils comprising a rotary indexing turret, a plurality of coil forms spaced at intervals around the turret, said turret being rotatable in steps to bring each coil form to a winding station and thence to an unloading station, each said coil form having a plurality of steps for winding coils of different sizes thereon, a flyer carried on a rotary and axially shiftable shaft for winding a wire on the coil form at the winding station, said turret being rotatable after the winding of the wire on the coil form at the winding station to bring an unloaded coil form to the winding station for proceeding with winding of the wire thereon without severing the wire, and means for shifting the shaft and the flyer for winding the wire on different steps of the coil form comprising a movable shift member, a connection between the shift member and the shaft, and a plurality of spaced stops each independently movable transversely with respect to the direction of movement of the shift member between a stop position in the path of the shift member for engagement by the shift member and a retracted position clear of the shift member, and means for selectively moving said stops each independently of the others between its said positions.
