Abstract
720,234. Making metal hollow-ware. SCAVULLO, V. K., SCAVULLO, F., SCAVULLO, C. J., SEAGERT, M. S., and SCOTT, M. S. Sept. 1, 1952, No. 21919/52. Classes 83 (2) and 83 (4). A metal hollow-ware article having a peripheral flange, such as a plate or platter, is made from stainless-steel sheet which is preformed into the desired hollow configuration 10 with its flange portion 10A, the latter is then embossed by passing it through co-operating roller dies 11, 12, and then the edge of the flange is formed into a half-roll. The sheet is preferably of 18-8 nickel-chrome stainless steel and is first deep drawn. An ornamental design is then embossed on the flange by the roller dies of which the bottom roller may be plain or may have a die surface complementary to that of the top roller. Both rollers or the top roller only may be driven. The edge of the flange is then formed into a half roll in a press by a beading die. The flange is work-hardened during these processes.
