ABSTRACT:
A three part die forms a metal clip into a fixed diameter, circular configuration about a workpiece. The die is comprised of three separate die members which move radially toward and away from a fixed center point that defines the center of a first circle. A die engaging groove or channel is defined in the surface of each die member for cooperation with the metal clip. When the die is closed, the die channel defines a second circle which is concentric to the first circle.
