Abstract

An armature includes a shaft supporting a slotted core and a commutator having peripherally spaced hook-like tangs. The armature is automatically wound on a flyer-type winding machine which has a set of concentric tubular shields surrounding the commutator and a pair of wire gripper units diametrically arranged relative to the shields. The gripper units are pivotally supported by a member which surrounds the shields and is supported for rotation on the axis of the armature shaft. A set of fluid cylinders are arranged to rotate or index the member and gripper units between a lead pick-up position and a lead terminating position through an intermediate winding position to provide for faster winding of each armature.
