A method and apparatus for manufacturing a two-part article from a cup (1) formed from a single sheet metal blank. The method includes forming a "V"-shaped groove (15) by pressing and rolling an anvil (25) on one side of the cup sidewall (3), against one or more cutting rings (21) on the opposite side of the sidewall. Generally, this stage is followed by a second stage, which cuts the cup (1) into a separate ring (11) and a shallower cup (10). This second stage enables profiled edges (17, 18) such as slight bends or flares to be formed which are beneficial when flanging or curling of the edges is subsequently required. |
