ABSTRACT:
A device and process which automatically forms centripetal transformer windings wound from outside diameter to inside diameter. The device includes an adjustable diameter ring which surrounds a mandril and can be clamped to or released from the mandril. Motors located on the ring each include a spacer arm which engages the mandril and a second arm which contacts and positions a wire at an adjusted radius as it is being wound into a turn of a transformer winding. The ring is vertically movable and the position of the second arm with respect to the mandril is also adjustable in order to form the turns of the transformer winding.
