Abstract: An armature commutator associated with a slotted core is constructed with a temporary tang structure which is employed during winding on a tang-type winding machine. After the core is wound and the commutator bars are connected, the temporary tang structure is removed resulting in a lead loop-type wound commutator.

Abstract: Apparatus for manufacturing dynamoelectric field windings having plural edge would coils formed from wire strapping includes a mandrel with a plurality of cores pieces. The mandrel is intermittently rotated about a first axis to present the core pieces to a winding station and rotated about a second axis to form an edge-wound coil about the core piece then present at the winding station. A wire feed and guide assembly having a wire forming head through which the strapping extends to the winding station assists in edge bending the strappng to form coils on the core pieces and is moved both vertically and horizontally to assist in edge bending transition strapping portions between successively wound coils. Also disclosed are a wire hook forming tool for forming a hook at the leading end of the strapping with which such leading end is held fixed to the mandrel, a wire cutting assembly for cutting the strapping to proper lengths and a movable tooling for shaping the windings as they are wound.

Abstract: A fast acting, high response wire takeup device that takes up and releases lengths of wire in response to changes in wire demand or tension required by a coil winder or the like includes two car mounted pulleys movable along straight, parallel paths and yieldably restrained against movement toward one another. Wire is guided to one of the pulleys and away from the other pulley along paths which are at acute angles to the stretch of wire between the pulleys and the moving mass associated with the pulleys is minimal so that relatively large lengths of wire may be rapidly taken up and released as required. Modifications are also disclosed.The wire demand or tension responsive takeup device is disclosed as part of apparatus for supplying wire to the shuttle spindle of a high speed stator winder, the apparatus further including a wire tensioning device and a powered takeup device operated synchronously with the shuttle spindle.
