The embossing bell and the inner shape embossing element each are provided with an embossing shoulder, which are disposed, with respect to the corrugated profile of the stripper ring, in the stroke direction in such a way that the shoulders can seize the burrs only alter the corrugating step. The corrugating step takes place prior to burr compression. The outer and inner contours of the disk are not able to change positions, but are able to change shapes on the burr side after the corrugating step.
