ABSTRACT:
A method and apparatus are provided by which the windings of an armature are cut near their opposite ends and then the windings or coil segments are preferably simultaneously forced from all the armature slots. An apparatus is described for carrying out the process in which after the coils have been cut circumferentially at their opposite ends, the armature and an annular array of stripping blades are brought into engagement so that the blades enter the slots of the armature and force the armature coil segments out of the armature slots. In the preferred embodiment the number of stripping blades coincides with the number of armature slots so that a stripper blade enters each slot and forces the coil segments out of all of the armature slots simultaneously. The preferred apparatus also includes a blade guide which maintains the blades in registration with their associated armature slots, the blades being radially spring biased and so shaped that if a blade does engage an obstruction such as the end of the armature core, the blade is free to move radially outward to clear the obstruction. A carriage assembly for carrying the armatures into and out of alignment with the stripper assembly and for securing the armature while it is being stripped are also disclosed.
