Beschreibung
Zusammenfassung:	The invention relates to a method and a device for producing a shaped part from a circular blank, wherein the circular blank is rotated and at least one compression roller is radially applied to an outer edge of the circular blank, said compression roller having a circumferential shaping groove. The outer edge of the circular blank is compressed to form a thickened region, which is shaped according to the shaping groove of the compression roller to form a thickened edge contour. With the radial compression, at least two axial shaped rollers are applied to an outer region of the circular blank, which cooperate when shaping the edge contour. According to the invention, at least in a starting phase of the radial compression, the two axial shaped rollers are applied to the thickened region at an axial shaping distance to one another, which distance is smaller than an axial width of the shaping groove of the compression roller, wherein the thickened region is axially compressed back.
