03-GP-5249 APPARATUS AND METHOD FOR AXIAL INSERTION OF DYNAMOELECTRIC MACHINE END TURN INSULATION ABSTRACT OF THE DISCLOSURE A preferred method proceeds with coil injection equipment having phase windings confined by axially extending gaps defined by the equipment tooling; positioning insulation retaining and shedding means within the tooling; and draping phase insulation with legs in some of the gaps. When the legs are ribbon type, the legs are twisted, i.e., angularly oriented so that they will enter core slots in edgewise fashion. The sheet- like end turn insulating portions are confined so that at least portions thereof establish a cylinder within the tooling. At least part of one leg is moved into a core slot by moving the core axially onto the tooling. After seating and clamping the core, the coil injection equipment is actuated, the phase insulation is shed into slots of the core, and windings are axially placed on the core. Preferred apparatus has a main drive rod that undergoes an initial icrement of travel without corresponding movement of a wire stripper because of a lost motion connection. During the initial travel increment, the phase insulation is moved axially and stripped radially outwardly onto the core. Preferred apparatus also includes a compound blade alignment and insulation holding and stripping device, at least parts of which are formed of an elastomeric material, and parts of which constitute rigid phase insulation moving and stripping fingers. The device also preferably includes a cylindrical section sized to fit within the coil injection tooling.
