Embodiment Construction

[0063] Figure 1a A laminate floor panel 1 according to known technology is shown, comprising a surface layer 5 , a core 6 and a balancing layer 7 . Figure 1c A surface layer 5 is shown. This surface layer 5 has an upper wear-resistant layer 13 made of a transparent material with excellent wear resistance. This wear layer generally consists of a transparent paper impregnated with melamine resin to which particles 12 of aluminum oxide have been added. A decorative layer 10 comprising paper with a printed pattern 11 is impregnated with melamine resin and placed under this transparent wear-resistant layer 13 . The wear layer 13 and the decorative layer 10 are laminated under pressure and heat to a core, typically a fiber based core (eg HDF), forming thereon a surface layer 5 about 0.2 mm thick. Figure 1b A balancing layer 7 is shown, which is also typically melamine impregnated paper. This balancing layer keeps the floor panels flat as humidity changes over time. The trans...

Abstract

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).

Description

technical field [0001] The present invention generally relates to, but is not limited to, the field of wood fiber based building panels, preferably floor panels, with a thin surface layer. The present invention relates to, but is not limited to, building panels having such a surface layer and apparatus and methods for manufacturing such panels. [0002] The invention is particularly applicable to floating floors formed from floor panels having a wood fiber core and a thin decorative wear-resistant surface. The following description of the prior art, the problems of the known systems and the objects and features of the present invention (as a non-limiting example) is therefore first of all directed to this field of application, in particular the field of flooring similar to conventional wood fiber based laminate floors. [0003] It should be emphasized that the invention can also be used in other applications such as wall panels, ceilings and furniture components. Background...
