Abstract

For manufacturing a multi-layer structure with repeating layer sequences, a band-shaped carrier material is first partially separated into individual sections of a same size with connections capable of bearing remaining between the individual sections. After continuously applying at least one further material layer on the surface of the carrier material, the individual sections are completely separated by cutting or punching. The multi-layer structure is obtained by stacking the individual sections obtained in this way on top of one another, whereby intermediate layers can also be potentially inserted between two individual sections.
