Abstract
A domed cap button collet and the method and apparatus for the manufacture of same by deforming a flat domed button collet having an elastic body including: a shank; a radially extending plate-like flange located one end of the shank; and, a cap formed of malleable material overlying the outer surface of the flange and crimped to the peripheral portion of the flange. Pressure is simultaneously applied to bend the flange and cap member into a substantially convex dome shape. Upon removal of the pressure, the cap member retains its dome shape and the flange member reverts to its original plate-like configuration.
