A device for producing embossed structures in a surface (5a) of a cylinder (5) comprises an electromechanical engraving unit with a stylus (4), which is movably mounted on a base of the engraving unit for working the surface (5a), a drive (23) for moving the stylus (4) in relation to the base, in a direction perpendicular to the surface (5a) of the cylinder, and a mechanism for setting and maintaining a basic distance between the base of the engraving unit and the surface (5a) of the cylinder (5). The electrochemical engraving makes it possible to produce embossed structures on cylinder surfaces (5a) quickly and at low cost. Used for example as basic elements for the embossing cylinders are copper-coated engraving cylinders (5), which, once the embossed structures have been introduced, are provided with a chromium film to increase the hardness and resistance. |
