ABSTRACT:
The disclosure herein describes a method for producing a structure, more particularly a wooden structure, in the surface of a hardened fibreboard, especially a medium-density fibreboard; it comprises the steps of: applying a resin-water mix to the surface of the fibreboard on one or both sides to soften and penetrate into the surface of the fibreboard; and pressing the fibreboard with a short-cycle press, under the action of pressure and heat, and using a structured pressure-plate. The water-part of the resin-water mix is caused to evaporate and the resin-part to cure, whereas the structure of the pressure-plate is moulded into the surface of the fibreboard.
