A method and apparatus for protecting the slot liner cuffs during insertion of prewound coils in the manufacture of stators for electric motors and other dynamoelectric apparatus. In order to protect the slot liner cuffs, which protrude beyond the face of the magnetic core, a plurality of movable fingers are positioned between the cuffs of those stator slots which have the greatest slot fill. As the windings are pulled into the appropriate slots of the magnetic core, they ride over and are at least partially supported by the highly polished surfaces of the fingers, which are in close proximity to the liner cuffs and extend slightly beyond the ends of the cuffs. This prevents the full force of the coil from being exerted against the cuffs as the coil is pulled into the slots, thereby avoiding damage to the cuffs which may otherwise result in exposing the wires of the coil to the sharp edges of the stator core. |
