Abstract: A method of treating winding means of a dynamo-electric machine core with a liquid adhesive material. A plurality of winding coils have opposite side turn portions received in slots provided therefor in the core and opposite end turn portions arranged adjacent opposite end faces of the core, respectively. In practicing this method, the core is rotated in one direction, and the liquid adhesive material is dispensed onto the opposite end turn portions of the coils with a greater amount of the liquid adhesive material flowing therefrom generally along one of the opposite side turn portions of the coils into the slots of the core in which the one opposite side turns of the coils are received than along the other of the opposite side turn portions of the coils into the slots in which the opposite side turn portions of the coils are received in response to the rotation of the core in the one direction.
