Abstract: Apparatus for winding coils to be placed in the slots of a stator of an electric motor or the like, comprising a rotary indexing turret having four coil forms spaced at intervals therearound adapted for rotation to bring each coil form to a winding station and thence to an unloading station, and means adjacent the unloading station for placing the coils in the slots of a stator. Each coil form has steps for winding a group of coils of different sizes thereon, winding being effected by a flyer which is shifted for winding coils on the different steps, and which may be traversed for level winding the wire. The wire is wound without severing it between successive coils of each group, and without severing it between successive groups, and a group of coils unloaded from the coil form at the unloading station is placed in the slots of a stator while another group is being wound at the winding station.

Abstract: A method of providing a stator of the type having a bore and slots extending outward from the bore with a set of pole windings in which a wire is wound into a plurality of groups of coils of different sizes, each group constituting a pole winding of the set, for placement in the slots of the stator without severing the wire between successive coils of each pole winding and without severing the wire between successive pole windings. Each pole winding is wound at a winding station and moved, following completion of its winding, to an unloading position. Each pole winding of a set of pole windings, after movement to the unloading position, is transferred to a means located adjacent the unloading position for placing the set of pole windings in the slots of the stator without severing the wire between the successive pole windings of the set. The wire between the last pole winding of said set and the first pole winding of the next successive set is severed. A stator is placed on the placing means, and the latter is operated to place entire set of pole windings in the slots of the stator in a single operation.
