Stator winding apparatus
First Claim
1. Stator winding apparatus for winding field coils onto pole pieces of a stator located at a winding station using wires supplied from sources of wire under tension, said apparatus comprising:
- a winding head assembly located adjacent said winding station that winds coils of wire on the stator at said winding station;
two pairs of winding forms for guiding the wires wound into coils wound on the stator at the winding station;
a pair of winding form-loading mechanisms that move said winding forms toward and away from one another at said winding station; and
a pair of programmably adjustable form lock assemblies adjacent said winding station that lock said winding forms to the stator located at said winding station and, after the winding operation is completed, unlock said winding forms from the same stator while said stator is still located at said winding station.

Abstract
A stator winding machine has a turret plate mounted for rotation about a vertical axis with stator clamp mechanisms mounted at spaced locations around its periphery for clamping stators to the turret plate with the axes of the stators coplanar with the axis of reciprocation and oscillation of the winding shuttle used to wind coils on the stators. The turret plate is repeatedly indexed in one direction about its vertical center axis to repeatedly sequentially move each of the stator clamp mechanism to a load/unload station, an optional idle station, a winding station, a coil lead terminating station, and then back to the load/unload station. Parts of the machine are quickly replaceable and other parts are programmably adjustable to accommodate different stator configurations.
