Patent DE-4031547-A1 (DE)
Inventor: BOPPEL WOLFGANG
IPC: B23K15/08
Filed: 1990-10-05
Abstract: The invention concerns a process for the surface treatment of a texturing roller, an electron beam being used to produce a figured surface on the roller. In this process, the roller is exposed, during the production of a recess in the surface, for at least two periods of time to an electron beam of energy density sufficient to produce a recess. During at least one of the intervals separating these periods of time, the surface is exposed to an electron beam of an energy density which leaves the recess essentially unchanged in size.
