Abstract
A device for embossing the edge of round blanks, in particular coins, has a forming wheel which is provided with roll-forming segments. The forming wheel has associated abutment elements which may likewise be mounted on forming wheels. A positioning device guides the round blanks, in coordination with the equally directed synchronous rotation of the forming wheels between the forming wheels and, after edge embossing has taken place out of the wheel interspaces.
