The first group (21) of stamping segments have a conical region with a geometry tapering on the axial direction and the second group of stamping segments have a conical region with a geometry fitting the geometry of the first group and diverging in the axial direction. An independent claim is also included for a method for deforming a stamp of a processing tool.
