Definitions

• the invention relates to a method of surface structuring in panels, furniture panels or the like by pressing.
• the object of the invention is to provide a method of surface structuring with which the reproduction of such pronounced, very rough and, in particular, natural structures is made possible in the case of panels, furniture panels or the like.
• the method of the invention offers a number of advantages.
• the panel By pressing more than three layers, up to ten layers or more, preferably about eight layers, the panel is given a sufficient thickness, with three layers of about 4 mm and 8 or 9 layers of about 25 mm to the natural bumps of a bark or a comparable natural structure, down to an inch range, to reproduce.
• the layers are pressed on a press table under a structured press die. This ensures that the back of the pressed, finished panel is flat, while a visible side is structured to a considerable extent.
• a hydraulic press that can easily apply the necessary pressure for a deformation in comparison to calender rolls.
• a top layer is a wood veneer and a second layer is color matched to the top layer.
• the method according to the invention is particularly well suited for a manual process with large panels of dimensions of about 2.50 m by 1.5 m, and therefore for panels of an area of more than 2 m 2 , very well. It has proved to be useful if the layers are pre-sorted by a side table placed on the press table and while the layers are alternately provided without adhesive application and with double-sided adhesive application, to be then pressed.
• the ram pressure should be more than 250 kg / cm 2 and should be evenly distributed over the ram as evenly as possible with several press cylinders of a hydraulic press.
• the ram has a structure that corresponds to a natural, multiply mirrored and juxtaposed.
• a natural surface structure of the ram considerably, since this surface structure in particular has no breaks, since, assembled mirrored accordingly, the actually completed, natural structure continues in mirror image at the edges.
