Abstract

A method for producing a cutting or embossing roller having a cutting knife or embossing projection that projects out of the surface of a base body of the roller ensures the greatest possible optimal homogeneity of the cutting knife or the embossing projection, while minimizing production duration and costs. Single-layer or multi-layer application of the cutting knife or the embossing projection onto the roller base body occurs by laser resurfacing welding. Each layer is produced using an additional powdered material, which is melted in a melt bath at the weld point. The heat and/or light radiation emitted by the melt bath is detected, at least during application of each layer. Laser power is controlled or regulated as a function of the heat and/or light radiation emitted by the melt bath, so that melt bath temperature remains essentially constant during application of each layer.
