Abstract

The instant invention relates to a multi-stage stamping-bending method for introducing a primary and at least one secondary structure into a band-shaped metal foil, wherein, after passing through the multi-stage stamping-bending method, the metal foil encompasses at least two 180° bends between primary and at least one secondary structure along the wave train of the primary structure within one wave of the primary structure, in the case of which the primary structure is introduced into the metal foil during a first bending method step so as not to be formed completely in all of its areas, in the case of which the primary structure is embodied completely in its remaining areas during a subsequent second bending method steps and in the case of which the at least one secondary structure is introduced into the metal foil in a completely formed manner during a subsequent third bending method step, wherein the metal band passes through the method steps back-to-back.
