Abstract (en)
[origin: WO0172446A1] A non-precurled, non-curled shell (112) is transferred to a reform station containing a coin die (122) and a coin punch (212). The coin die has the desired round finished blank diameter machined into its face. The die cavity has a round die wall (126) which stops the outward flow of material during the coining process. The die wall produces the blank's final shape. During the coining process, the coining punch compresses the scalloped blank edge of the non-curled, non-precurled shell. The coined area causes material to flow outward, coming in contact with the die wall, forming the blank's outer perimeter.
