Abstract
A method of manufacturing a building panel, including mixing wood fibre particles and a binder to form a first mix, applying the first mix, while the first mix is in powder form, on a core for forming a sub layer on the core, applying a surface layer on the sub layer, wherein the surface layer comprises a second mix of wood fibre particles and a binder, pressing the core, the surface layer, and the sub layer, under increased pressure and temperature, and forming them into a building panel. A building panel formed by the method.
Claims18
A method of manufacturing a building panel, comprising:
- mixing individual unbonded wood fibre particles and a binder to form a first mix;
- applying the first mix on a core for forming a sub layer on the core;
- applying a surface layer on the sub layer, and
- pressing:
- the core,
- the surface layer, and
- the sub layer,
- under increased pressure and temperature, and forming them into a building panel,
- wherein the core is pre-fabricated before the first mix is applied on the core, and
- wherein the binder in the first mix is an uncured dry powder when the first mix is applied on the core for forming the sub layer and when the surface layer is applied on the sub layer, and
- wherein the pressing step creates a surface embossing of at least 0.5 mm.
