Embodiment Construction

[0155] figure 1 A perspective view of an extruded plate 1 according to the invention is shown, which is designed to be flat in the exemplary embodiment shown. In the case of endless belts, however, the embossing tool can also be curved. The extruded board 1 shows a grain 2 which imitates the shape of a wooden structure. However, it is conceivable to produce other textures or other surface properties in this way by means of the method according to the invention and the etching method required for this.

[0156] figure 2 Shown is an enlarged side view of a part of the front edge region of the extruded plate 1 and a structure 3 lying thereon, which has a mountain-like surface with a plurality of recesses 4 and elevations 5 . In this case, the surface is produced by one or more etching processes, whereby the form is first coated in a standard manner or digitally with printing techniques, the regions that are not to be subjected to the etching process being masked. For example...

Abstract

The invention relates to a method for processing a structured surface of an embossing tool, in which the entire surface is provided with a first metallic coating (6) and said surface having, in selected regions (7, 8, 9, 10, 11), at least one additional metallic coating that has a differing degree of lustre. To improve the optical properties of the material boards produced using the embossing tools, particularly if reproducing a wood texture, the invention suggests that additional differing degrees of lustre should be produced in multiple selected regions (7, 8, 9, 10, 11) on the first coating (6), and be produced by a combination of metallic coatings and mechanical or chemical after-treatments. Therefore, for example, a wood pore with a defined structure can be substantially better reproduced, and the optical and haptic properties of the wood composite board produced using the press plates can thus be improved.

Description

technical field [0001] The invention relates to a method for treating the surface of an embossing tool, wherein at least one surface is completely subjected to a first treatment step in order to obtain a gloss, and at least one further treatment step is carried out in selected areas, for different gloss levels. Background technique [0002] Similar embossing tools are required in the woodworking industry, especially in the manufacture of wood panels. By embossing the visible surface of the wood panel with the embossing tool, a realistic imitation of the desired subject matter, preferably the natural surface structure, can be produced. For this purpose, the wood panels, preferably produced by press cutting, are coated with, for example, a resin film, which is then pressed together with the wood panels under pressure and temperature in a hydraulic heating press. During extrusion, the resin film becomes liquid under pressure and temperature and polycondensation occurs. Extru...
