The method has a transported material web provided with structured images, e.g. printed images (1), embossed images (2) and perforation images via successive processing steps, overlaid by a cut image (5), dividing the material web into partial webs, in a final processing step. A velocity-regulated laser beam is directed onto the material web, a detectable laser line (4) provided by material removal or a material thickness variation, with laser markings provided along the laser line by varying the laser radiation duration or power level, used for providing signals controlling the next processing step. |
