Numerous industrial, mechanical and household products require that patterns be cut into their metal surfaces. A metal container lid having an apertured design with rolled edges is stamped by a method and apparatus incorporating a cushioning pad between a die and the metal sheet, which is then stamped with a perforating punch. The punch is used to cut through the metal sheet and pad to stamp the metal sheet with the design and roll the metal edges of the design.
