ABSTRACT:
A process for winding a wire segment to form a wire coil includes the steps of rotating a mandrel by contacting the mandrel outer surface with a moving belt, and directing the wire onto the rotating mandrel between the belt and the mandrel outer surface. The belt holds the wire against the mandrel, and as the mandrel rotates, the wire is wound into a coil on the mandrel outer surface. The belt continues to contact the coil outer surface and to rotate the mandrel until the entire length of the wire segment is wound. As the thickness of the coil increases, the belt partially unwraps from the coil outer surface to adjust belt tension. In one embodiment of the present invention, the belt passes around a pulley attached to a rotatable ring which moves the pulley in a circular path about the axis of the mandrel to cause the belt to unwrap from the coil as the wire builds up on the mandrel.
