Abstract:
A method of manufacturing a swaging ring, wherein a metal strip having an ordinary thickness and presenting two ends is rolled into a hoop and wherein said ends are ends connected together by a connection element having a thickness at the most substantially equal to said ordinary thickness and presenting at least one anchor edge, and wherein, to connect said connection element to one end of the strip having a thickness substantially equal to said ordinary thickness, the connection element is placed against said end in such a manner that said anchor edge of the connection element is in register with said end, and pressure is exerted on the connection element in such a manner as to upset the material of said end of the strip lying beneath the connection element while providing a fixing member in said end suitable for co-operating with said anchor edge to hold the connection element and said end of the strip relative to each other in such a manner that a thickness of the ring in the region of the connection element is substantially equal to said ordinary thickness of the strip.
