Patent ID: 7647698

Claim:
A method for producing a cutting or embossing roller having a cutting knife or embossing projection that projects out of a surface of a base body of the roller comprising the following steps: (a) applying by laser resurfacing welding at least one layer of the cutting knife or the embossing projection onto the base body of the roller, each layer of the at least one layer being produced using an added material in powder form melted in a melt bath at a weld point; (b) detecting heat or light radiation emitted by the melt bath at least during application of each layer; (c) controlling or regulating power of a laser used in the laser resurfacing welding as a function of the heat or light radiation emitted by the melt bath so that melt bath temperature remains substantially constant during application of each layer; and (d) setting a wavelength of a laser beam emitted by the laser as a function of an absorption capacity of powder particles that form the added material in powder form.
