Embodiment Construction

[0055] figure 1 The pressed sheet 1 is shown in a perspective view, which may be used to produce a material sheet. In the illustrated embodiment, the pressed board 1 has a surface structure 2 corresponding to the wood texture. The pressed sheet 1 is manufactured according to the method according to the invention using digital data of 3D topography, wherein the structured part is manufactured by applying a large number of individual 2D layers. After the surface structuring has been completed, a chromium layer is applied over the entire surface or locally, and if necessary, several chromium layers are also applied. Therefore, the pressed sheet 1 can be used for pressed material plates.

[0056] figure 2 The cross section of the pressed sheet metal 1 with the surface structuring 2 is shown in a strongly enlarged view. Here, a large number of individual layers 4 are applied to the carrier sheet 3, which in their shape correspond to the desired surface structure. The individual la...

Abstract

The invention relates to a method for producing a surface structure of a pressing tool, in particular a pressing plate or endless belt, for pressing material plates, plastic films, separating films, PVC surfaces, LVTs (luxury vinyl tiles), cheque cards, passports, credit cards, or plastic cards, comprising the following steps: providing and using digitised data of a 3-D topography of a surface structure, creating digitised data of individual 2-D layers of the 3-D topography, and using the digitised data of the 2-D layers to guide a processing head (28) and / or position the processing head in an xy-plane, or to move a work table (21) in the plane spanned by an x-y coordinate system in relation to a stationary processing head, in order to connect a layer material to an existing carrier material or an already completed layer on the basis of the digitised data of the 2-D layers.

Description

Technical field [0001] The present invention relates to a method for manufacturing the surface structure of a pressing mold, especially a pressing sheet or continuous belt, the pressing mold is used for pressing material plates, plastic films, separation films, PVC surfaces, LVT (luxury vinyltiles, luxury vinyl tiles). ), cheque card, passport, credit card or plastic card. Background technique [0002] For the furniture industry and for interior finishing, for example for laminate flooring, material panels, such as wood material panels, are required. The material board has a core made of MDF or HDF, in which layers of different materials such as a decorative layer and a protective layer (covering layer) are placed on at least one side. In order to avoid warping of the material plate manufactured, the same number of material layers are usually used on both sides of the material plate, wherein the material plates are pressed against each other and the surface is simultaneously per...
