Problems solved by technology

The disadvantage of this method is that with this process only raised structural elements of the structure can be polished on the stamped strip or stamped plate
In addition, these methods are not ecologically sound and they have high energy requirements

Embodiment Construction

[0026] figure 1 A punched sheet surface is shown, which has been treated by the method according to the invention in the lower part of the illustration. It can be seen that the entire lower half of the sheet is surface-treated, wherein the previously determined surface structure in the striated section has a different gloss in the area that has the opposite structure bottom relative to the adjacent structure area a certain minimum altitude.

[0027] figure 2 A stamped sheet surface is shown, the lower section of which in the illustration has been surface-treated according to the invention in such a way that approximately 50% of the entire surface has a high degree of gloss. All parts of the structured surface which are in the range between 25% and 75% of the total height of the surface structures are surface-treated according to the invention for this purpose. As a result, the surface texture has a lower gloss in the base of the structure and in its upper region.

Abstract

A method for adjusting the gloss level of a structured surface of a pressing tool, for example, a pressing sheet or pressing belt, is provided. An energetic beam, in particular a laser beam, is used to remelt at least part of the surface to a depth of 1 to 5 μm, more particularly from 1 to 3 μm. A method is thus produced that is substantially quicker and cheaper with respect to conventional polishing methods for pressing plates and which can be used to change the gloss level of the tool surface that is independent of the surface structure.

Description

technical field [0001] The invention relates to a method for adjusting the glossiness of a structured surface of a die, in particular a stamped sheet or strip. Background technique [0002] Surface-structured large-scale stamped strips (also called endless stamped strips) and stamped sheets are used for providing surface structures to substrates, such as in particular sheets or strips, for decorative or technical purposes. Surface-structured sheets or strips are used, for example, in the furniture industry, the flooring industry, the construction industry and the truck industry. The material is made, for example, of various plastics. Particleboard, plywood and medium density fiberboard are likewise used, which are laminated on their use side (upper side) or lower side with a film / paper / decoration impregnated with dense melamine resin. In the production of floors or truck floors, as in construction panels, a defined portion of corundum material is additionally added to the ...
