Abstract
The invention relates to a method for manufacturing profiled metal strips (1, 1′), in which a metal strip (1, 1′) with predefinable material thickness consisting, in particular, of stainless steel is wound up on a coil (4) and guided through a rolling stand (W1-W4) containing several rolls (2, 3, 2′, 3′), wherein at least the rolls (2, 3) that effectively interact with the metal strip (1, 1′) are provided with a predefinable topography (8, 9), by means of which profiles with profile depths >250 μm can be produced on both sides of the metal strip (1, 1′) depending on the geometry of the topography (8, 9) of the rolls (2, 3), and wherein the metal strip (1, 1′) is subsequent to its profiling wound up on a coil (5) and, if so required, subjected to a thermal post-treatment.
