Abstract
A device for shape-forming at least one recess in a film-type material features a die with at least one opening, at least one shaping stem that can be introduced into the opening to create the recess by shape-forming, and a clamping facility for holding the film-type material fast between the clamping facility and the die. Counter-stems which are displaceable at least within the die openings are situated in the die, whereby shape-forming regions of the shape forming stems and the counter-stems for clamping the film-shaped material are, at least in part, superimposed on each other.
