Apparatus and method for forming dynamoelectric machine field windings by pushing
First Claim
1. Apparatus for placing magnet wire in slots respectively defined by spaced elements extending from a support member thereby to form a dynamoelectric machine field winding, said elements having distal ends, said apparatus comprising means spaced from said distal ends on the side thereof remote from said support member for guiding said wire toward said elements, means for continuously pushing wire through said guide means, and means for moving said guide means, as said wire is being continuously pushed therethrough, relative to said elements in a path aligned with at least two of said slots and with a motion having components in at least two mutually perpendicular axes thereby continuously to push said wire into said slots without applying tension thereon and to guide the wire as it is being continuously pushed between said slots to form end turns.

Abstract
An apparatus and method for placing magnet wire in the slots respectively defined by spaced, parallel blades of coil transfer apparatus which lie on an imaginary cylinder thereby to form a dynamoelectric machine field winding. The wire is pushed and simultaneously guided with a motion having components in at least two mutually perpendicular directions in a path having sections respectively aligned with at least two of the slots thereby to push the wire into the slots, the path also having sections respectively within and outside of the cylinder.
