Abstract

PURPOSE: To provide a simple and easy method of producing nip rings for use in a pipe joint, while saving material, by coiling L-section hoop steel, cutting up the coil into one-pitch loops, and removing the spiral strain from the loops by pressing the cut ends in the direction of coil axis.
