Abstract
An armature winding machine has an armature winding core holder provided with a collet assembly for gripping the shaft of an armature core. The collet assembly has a plurality of releasable balls that connect the collet assembly to a support. A tool having a push rod and hooked fingers is used to release the balls and grasp the collet assembly for removal from its support. Another collet assembly can be mounted on the support with the tool. The armature winding machine has chucks with wire form or shrouds for guiding wire into selected slots in the armature core during the winding of the wire with the rotating flyers of the machine. The chucks are releasably mounted on supports so that they can be removed as a unit from the support and replaced with different sized chucks. The chuck and supports have cooperating connecting structure and locking dogs that releasably hold the chucks on the supports.
