Abstract
A method for producing a thickness-profiled metal strip in which at least one opening is produced in the metal strip and in a subsequent step, the metal strip is longitudinally rolled with at least one roller that penetrates into the metal strip in some regions across its strip width and thus a thickness profiling at least in the width direction of the metal strip is produced. In order to improve the reproducibility of the method, what is proposed is that at least one hole passing through the metal strip is produced as an opening in the metal strip, over which hole the roller that penetrates into the metal strip longitudinally rolls in order to produce the thickness profiling in the width direction of the metal strip.

A method for producing a thickness-profiled metal strip, comprising:
- producing at least one hole passing through a metal strip in a rolling region of the metal strip and, in a subsequent step, longitudinally rolling the metal strip with at least one roller that penetrates into the metal strip in at least one rolling region across its strip width and over the at least one hole, thus producing a thickness profiling at least in a width direction of the metal strip.
