Abstract

Fluid-pressure operable segments surrounding rod-deforming die are controlled by wire-diameter sensing device. As die wear occurs, sensing device responds to increased wire diameter and raises fluid pressure to advance segments inwardly against die thereby to constrict die and decrease diameter of die orifice.
