A lower platen is provided with a hem punch and a slide cam. The hem punch is floating-supported to the slide cam. An upper platen is provided with a hem punch driver cam and a liner. The hem punch driver cam is used to change the hem punch to a pre-hemming position and to a final hemming position.
