METHOD OF TREATING A LOOSE WOUND CORE, METHOD OF FABRICATING A LOOSE WOUND CORE, AND METHOD OF OPERATING APPARATUS A hardenable liquid adhesive material is dispensed onto opposite end turn portions of coils in winding means of a loose wound core with agreater amount of the liquid adhesive material flowing therefrom generally along one of the opposite side turn portions of the coils into the slots of a generally loose lamination stack of the loose wound core in which the one opposite side turn portion of the coils are received in response to the rotation of the loose wound core in one direction and with a greater amount of the liquid adhesive material flowing generally along the other of the opposite side turn portions of the coils into the slots of the loose lamination stack in which the other opposite side turn portions of the coils are received in response to the rotation of the loose wound core in another direction opposite the one direction thereby to generally equalize the liquid adhesive material fill of the slots. From the slots of the loose lamination stack, the liquid adhesive material flows generally by capillary action into wetting relation between the interfacing laminations of the loose lamination stack generally toward a circumferential surface thereof at least during the rotation of the loose wound core. A method of fabricating a loose wound core and a method of operating apparatus for bonding the loose wound core are also disclosed.
