Abstract
A method for manufacturing a rotationally symmetrical shaped article, which has a cylindrical, concentric hub axially closed on one side, in a shaping process is performed such that at least one pressure roll is in contact with a rotating, closed, planar circular blank sheet and presses the material of the blank radially from the outside inward against a projecting part that runs upright on the circular blank such that the thickness of the circular blank decreases and the hub including a blind hole is formed.
