WOOD FIBRE BASED PANELS WITH A THIN SURFACE LAYER

摘要

Floor board (1) comprising a wood fibre based core (6) such as HDF, a thin surface layer (5) such as wood veneer, and a sub layer (6a) between the surface layer (5) and the core (6). The sub layer (6a) comprises wood fibres (14) and an uncured binder (19) and is applied on the core (6) as a powder. The layers (5, 6a) are connected to the core (6) and embossed in register by heating and pressing, the uncured sub layer (6a) behaving similar to a paste or a liquid substance and creating a uniform counter pressure under the thin surface layer (5), thus providing an easier forming of deep and sharp embossing without damaging the surface layer (5).
