Abstract:
1. A method for manufacturing a clamp ring comprising the steps of: providing a strip of metal; cutting the strip into a rectangular shape; shaping the strip into a circle forming a body having a toroidal shape via a shaping technique, the strip of metal having a space between the two ends of the strip; and attaching two ends of the strip via a metal joining technique to form the clamp ring, the metal joining technique forming a seam to fill the space between the two ends of the strip; and bending the bottom of the ring to form an arc'd area, wherein the arc'd area is formed by using a shaping technique, the arc'd area having a top section and a bottom section, the top section being a radially outward bend and terminating at a distal end therefrom which defines a maximum diameter of the clamp ring, and the bottom section being a radially inward bend and terminating at a distal end therefrom which defines a minimum diameter of the clamp ring, where a curved section is located between the top section and the bottom section of the ring.
