Abstract

662,348. Making packing rings. MATTHEWS, E. F. (Wurzburger, P. D.). Feb. 8, 1949, No. 3468/49. Class 83 (iv). [Also in Groups XXVI and XXVIII] Corrugating.-A sealing-ring for pipe joints (see Groups XXVI and XXVIII), respectively, is made by confining the ends of a cylindrical ring R in a die A, B whilst leaving the intermediate portion of the ring unconfined on the outside, and shortening the ring to cause the unconfined portion to buckle outwardly. The dies A, B have cavities 13, 16 and recesses 14, 17, respectively, to shape the ring, and the die B has a spring-actuated plunger 18 to support it. Burrs on the ring are removed by the dies.
