摘要

The present invention proposes a process for making grooves in rolls which are suitable for the processing of web-like materials, a laser source directing a laser beam and a directed line directing a compressed-gas jet onto the roll surface, with the result that the roll material is removed in a sharply defined region and a groove is thus formed.
