Abstract

PURPOSE:To improve working environments and enable the stop ring grooves for fitting of stop rings to be readily molded by cold rolling a steel bar by the use of rolling rollers. CONSTITUTION:Two circular dies 2, 3 are held spaced by a suitable spacing and a steel bar is positioned in said spacing. While the circular dies 2, 3 are being revolved, they are gently approached and stopped in the specified position of the steel bar 1, whereby a ring groove 8 is formed.
