Abstract

The present invention is a method for forming grooves in rolls which are suitable for working web-like materials, wherein a laser source directs a laser beam and an aligned conduit directs a pressurized gas jet onto the roll surface, the roll material thus being removed in a sharply defined area and a groove thereby being formed.
