Abstract

A method to produce building panels is disclosed which method includes the step of applying a layer (5) comprising a mix of fibres (14), binder (12), and wear resistant particles (12) on a carrier (6), pressing the layer (5) with an embossed matrix (2a, 2b) and providing embossed portions (4) and filling the embossed portions with decorative a substance (3).

Claims

1. A method of manufacturing a building panel comprising the steps of:

applying a layer comprising a mix of fibres and a binder on a carrier;

pressing the layer with an embossed matrix and providing embossed portions; and

after pressing, filling the embossed portions with a decorative substance.

2. The method as claimed in claim 1, wherein the building panel is a floor panel.

3. The method as claimed in claim 1, further comprising an additional pressing that is made after filling of the embossed portions.

4. The method as claimed in claim 1, wherein the carrier is a wood based core.

5. The method as claimed in claim 1, wherein the carrier is a HDF board.

6. The method as claimed in claim 1, wherein the mix further comprises wear resistant particles.

7. The method as claimed in claim 6, wherein the wear resistant particles are aluminium oxide particles.

8. The method as claimed in claim 1, wherein the decorative substance comprises a colour pigment.

9. The method as claimed in claim 1, wherein the decorative substance comprises wear resistant particles.

10. The method as claimed in claim 1, wherein the decorative substance comprises wear resistant particles and a binder.

11. The method as claimed in claim 1, wherein the decorative substance comprises colour pigments and wood fibres.

12. The method as claimed in claim 9, wherein the wear resistant particles of the decorative substance are aluminium oxide particles.

13. The method as claimed in claim 10, wherein the wear resistant particles of the decorative substance are aluminium oxide particles.

14. A method of manufacturing a building panel comprising the steps of:

applying a layer comprising a mix of fibres and a binder on a carrier;

pressing the layer with an embossed matrix and providing an embossed portion; and

filling the entirety of the volume of the embossed portion with a decorative substance.

15. The method as claimed in claim 14, wherein the mix further comprises and wear resistant particles.

16. A method of manufacturing a building panel comprising the steps of:

applying a layer comprising a mix of fibres and a binder on a carrier;

pre-pressing the layer with an embossed matrix and providing embossed portions;

filling the embossed portions with a decorative substance; and

curing the layer under heat and pressure.

17. The method as claimed in claim 16, wherein the mix further comprises wear resistant particles.

18. The method as claimed in claim 16, wherein the decorative substance comprises a colour pigment.

19. The method as claimed in claim 16, wherein the decorative substance comprises wear resistant particles.

20. The method as claimed in claim 16, wherein the carrier is a wood based core.

21. The method as claimed in claim 16, wherein the building panel is a floor panel.
