ABSTRACT:
An apparatus for producing a metal sheet with a corrugation configuration that is of a first corrugation height, wherein the sheet has transversely or at an angle relative to the corrugation configuration a microstructure having a second, substantially smaller corrugation height. The apparatus includes a device for producing the microstructure, and a pair of mutually meshing corrugation rollers that are disposed downstream of the device for producing the microstructure. Wherein the corrugation rollers have at their outer surfaces recesses which are suitably disposed and sufficiently large to receive the microstructures, so that the microstructures are not deformed by the corrugation rollers in the operation of corrugating the metal sheet.
