Device for producing metal rings.

摘要

A metal ring producing device comprises a rigid roller (53) and a resilient roller (31). The resilient roller has an outer cylindrical portion covered with an elastic annular member (37). The resilient roller is positioned near the rigid roller so that a metal plate member (79) can be inserted between the resilient and rigid rollers. The resilient roller is rotated in a given direction. The elastic annular member is formed with equally spaced recesses (41,43). Each recess has a concave bottom surface which is shaped in conformity with an outer surface of the metal ring produced around the rigid roller. A ring removing mechanism (55) is further employed which pushes one end of the metal ring and thus thrusts the metal ring off the rigid roller when the resilient roller stops at a position wherein one of the recesses is registered with the rigid roller. <IMAGE>
