ABSTRACT:
A wire coiling apparatus employing a pair of coiling rolls with rigid, usually steel, backup and drive ring members in direct driven engagement with the mandrel spindle, coupled to work rings which have controlled resilient transverse floating action under coil forming pressures, to rotate off center relative to the drive rings which drive them. In one embodiment, each work ring has a steel forming surface which is part of a metal outer ring member mounted on a resilient inner ring member. In another embodiment, each work ring is a resilient member which has a resilient forming surface.
