Abstract
A mandrel for the winding of wire includes a central element and segments radially extending about and respectively coupled to the central element by rotatable arms that permit the segments to assume a collapsed position and an extended position Inner surfaces of the segments define slots in which ends of the arms extend. One segment also defines a radially extending groove on an outer surface of that segment which intersects with the slot of that segment to define an opening through the segment. A resilient pad is fixed in the slot of that segment and has a face located at the opening and adjacent a surface of an arm coupling that segment to the central element. A wire is threaded into the opening and held in place when the arms are rotated to cause the segments to assume the extended position. Methods using the mandrel are disclosed.
