[origin: EP1382404A1] Process comprises positioning a splitting roller (10) with a pointed separating edge (12) on the workpiece (1) rotating about an axis of rotation (14) and splitting off a material region (3). Cylindrical hub (5) is formed from this split-off material region using at least one post-forming roller (20). Before the end molding step the split-off material region is provided with a defined curve shape. Independent claims are also included for the following: (1) Splitting roller with a pointed separating edge; (2) Intermediate molding roller; and (3) Pressure rolling machine.
