Abstract
The invention relates to a process and apparatus for producing a rough and hard generated surface on a cylindrical body of rotation, more particularly a roll for metal strips. To rapidly obtain as uniform a surface roughness as possible, the body of rotation (2), acting as a cathode, is immersed over its whole length into an electrolyte (1) in a tank (3) only to such an extent that the immersed peripheral portion is narrower by a multiple than a plate-shaped anode (5) disposed opposite the body of rotation and extending over its whole length. The electrolyte can contain a substance suitable as a finishing deposit on the generated surface.
