ABSTRACT:
A flier-type armature winder winds armatures consisting of a commutator with circumferentially gapped tangs and an armature core, co-axially mounted on a common shaft. In operation, at least one flier winds coils of wire successively onto the armature core and a shield covers the commutator tangs to prevent them from being accidentally engaged by the wire. After each winding of the wire coils, a wire lead from the last wound coil is looped about a corresponding one of the commutator tangs. The wire loop is formed by first securing the wire lead to wire-engaging means located on the shield. Then the shield is moved to substantially align its wire engaging means and the secured wire lead with a first one of first and second gaps in the commutator which are disposed at opposite sides of the corresponding tang. Next, the shield is retracted from the commutator tangs to lay a trailing portion of the wire lead in the first gap. The stretch of wire lead between the first gap and the wire-engaging means is then bent completely across the corresponding tang by rotating the shield to substantially align its wire-engaging means and the secured portion of the wire lead with the second gap. At the same time or subsequently, the bent wire is looped partially about the corresponding tang by returning the shield along its rotational axis to again cover the commutator tangs.
