ABSTRACT:
A method and a tool for fabricating a toothing at a three-dimensional body produced by forming and fine blanking, especially an attachment for car seat components or the like produced out of a flat strip, wherein the flat strip by forming and fine blanking in a tool is formed into a pot-shaped body with inner forms and a substantially evenly curved edge. Afterwards, a toothing is fabricated into the edge radially extending to the inner side of the body. The toothing in the edge of the pot-shaped body is exclusively produced by cutting and/or shaving with a fine blanking die and/or a shaving device, and a burr and/or shaving chips developing during cutting and/or shaving are pressed into a recess in the base of the pot-shaped body allocated to the toothing.
