Abstract
Disclosed is a process for the production of synchronous-pore layered materials. Also disclosed is a device for the conduct of the process. In further aspects, the invention relates to layered materials which can be produced by the process, and also to wood-composite boards equipped with the layered materials produced by the process of the invention.
Claims24
A device for the production of synchronous-pore layered materials, comprising:
- at least one printing line for the production of a printed decorative effect on a carrier material, the at least one printing line comprising at least one digital printer;
- at least one means for drying of the carrier material after printing of the printed decorative effect;
- at least one means for impregnation of the carrier material with a resin;
- at least one means for drying of the carrier material after impregnation with the resin;
- a press, the press being configured to have the carrier material, at least one impregnated core ply, and a structure-former introduced therein, the press being further configured to have an impregnated overlay or a material for production of a protective layer introduced therein;
- at least one means for measurement of the dimensions of the structure-former, configured to make measurements of the dimensions of the structure-former after at least one passage of the structure-former through the press;
- at least one means for measurement of dimensional changes of the carrier material;
- and
- at least one set of control equipment, wherein said at least one set of control equipment comprises a separate control unit for controlling a digital printing procedure.
