Abstract: A device for structuring the surface of a metal pressed sheet or of an endless strip, comprising a support device adapted to support the metal pressed sheet or endless strip during structuring, and a spray head and a slideway adapted to permit movement of the spray head into a desired position within a plane defined by an X and a Y coordinate. The spray head is further adapted to move in a Z direction with reference to a work surface which is spanned by the X and Y direction, and the spray head is guided by means of a digitalized template that is identical to the printed image of an impregnated paper used in a further pressing process. Independent drive elements are connected to a control unit and configured to move the spray head into the desired position.

Abstract: The invention relates to a method for producing a metallic pressed sheet or an endless strip, whereby a surface structure is produced by applying a mask for partial chemical passivation followed by chemical surface treatment. The invention also relates to a device for implementing said method. In order to significantly improve the reproducibility and the resolution of the mask obtained, the mask is produced from a UV-hardening lacquer which is applied by a suitable device. The resolution is improved by means of a nozzle matrix which sprays the UV-hardening lacquer in dots, the individual dots forming a pattern as a result of the overspraying thereof, thereby forming the mask to be produced. The UV-hardening lacquer is especially advantageous in that it can be removed from the surface very easily after the etching process, and enables a high reproducibility compared to the conventional screen printing methods.

Abstract: The invention relates to a method for processing and producing a surface of a material with a reproducible degree of lustre and to a press for carrying out said method. The aim of the invention is to increase the stability of the press. To achieve this, a press is provided with a coating that consists of carbon with diamond-like layers and that adheres to the surface of the press. Said coating has a layer thickness of between 0.1 and 10 ?m and a surface hardness in excess of 1800 HV (Vickers). The attrition of the surface of the press is thus significantly reduced during the processing of abrasion-resistant materials.
