ABSTRACT:
In the winding of an armature having a slotted commutator by a flier-type armature winding machine, a finish wire is severed closely adjacent its associated commutator bar slot by clamping a segment of the finish wire to a fixed tooling piece after it is wedged into the commutator bar slot by a linearly movable clamp rod having a finger which extends into the path that the start wire takes at the beginning of the winding of the next armature. The start wire is, accordingly, looped around the finger at the beginning of the winding of the next armature. The clamp rod is thereafter moved away from the fixed tooling piece, carrying the loop of wire with it. During the latter movement, the loop of wire is stripped from the finger by a cam surface past which the finger moves. The machine is provided with quick change wire guide tooling parts and quick change tamping blades so that the machine may be rapidly retooled for maintenance or for winding armatures having different parameters. The tamping blades move purely linearly through small distances during the tamping operations.
