ABSTRACT:
This invention provides for stamping of the platforms of a ball retainer on one side of the surface of the metal band and of the spherical seats on the other side of the surface of the band in a single continuous operation or in several operations. Two mating punches are used in order to stamp out the desired ball retainer. A first punch has rectangular upwardly projecting lugs and spherical recesses and the second punch has spherical outwardly extending lugs and rectangular recesses. As these two punches are moved toward each other, they cause the platforms and the spherical seats of the ball retainer to be stamped in the metal band. The lugs on each of the punches and the side surfaces of hollow recesses of the dies are provided with cutting edges, which cut out the ball retainer from the metal band.
