Abstract

A panel, in particular a floor panel, has a core of a wooden material, in particular MDF or HDF, or a wooden material/plastic mixture. A pattern is arranged on a visible side. The visible side is provided on at least one side edge (I, II) with a chamfer running at an angle α hereto and a length (L). The angle α of at least one of the chamfers varies over the length (L).

Claims

1. A method for producing a panel with a core of a wooden material, comprising guiding a side edge (I or II) of the panel past an oscillating machining tool which oscillates about an axis running parallel to a transport direction (T) of the panel to form a chamfer having an angle which varies over a length.

2. The method according to claim 1, wherein the machining tool is a laser.

3. The method according to claim 2, wherein the machining tool has a mass unbalance to generate the oscillation.

4. The method according to claim 1, wherein a pattern is directly printed on the top of the panel.

5. The method according to claim 1, wherein a pattern is applied to a paper web which together with a synthetic resin layer is pressed to a visible side of the panel.

6. The method according to claim 1, wherein a pattern is printed out directly onto the chamfer.

7. The method according to claim 6, wherein a relief is embossed in a surface of the chamfer.

8. The method according to claim 7, wherein onto the pattern on the chamfer a synthetic resin layer is applied and the relief is embossed in the synthetic resin layer.

9. The method according to claim 6, wherein the pattern is printed directly onto at least one of the visible side and the chamfer.

10. The method according to claim 6, further comprising embossing a relief in a surface of the chamfer which corresponds to a structure of the pattern.

11. The method according to claim 1, wherein a chamfer is formed at two opposite side edges (I, II) of the panel.

12. The method according to claim 11, wherein the chamfer is formed at all side edges of the panel.

13. The method according to claim 10, wherein the structure is a wood grain.

14. The method according to claim 1, wherein a size of an angle of the chamfer varies arbitrarily over the length (L) of the chamfer.

15. The method according to claim 1, wherein the chamfer is flat or curved in a convex or concave manner.

16. The method according to claim 14, wherein the angle varies in a range of 15°

-89°

.

17. The method according to claim 16, wherein the angle varies between 37°

and 42°

.

18. The method according to claim 1, wherein the wooden material is MDF or HDF or a wooden material/plastic mixture.

19. The method according to claim 1, wherein a lower edge of the chamfer is cut straight, based on the visible side, such that an impermeable connection of two panels is provided.

20. A method for producing a panel, comprising guiding a side edge (I or II) of the panel past an oscillating machining tool to form a chamfer having angle which varies over a length and at its lower edge runs straight.

21. The method according to claim 20, wherein the angle is in a range of 15°

-89°

.

22. The method according to claim 21, wherein a relief is embossed in a surface of the chamfer.

23. The method according to claim 22, wherein a pattern is printed directly on a visible side of a core of the panel and the chamfer such that the visible side is devoid of a decorative paper or carrier layer.

24. The method according to claim 23, wherein a synthetic resin layer is applied on the chamfer.

25. The method according to claim 24, wherein a relief is embossed in the synthetic resin layer surface of the chamfer which corresponds to the pattern printed directly onto the visible side and the chamfer.

26. The method according to claim 20, wherein the machining tool oscillates about an axis running parallel to a transport direction (T) of the panel.

27. The method according to claim 20, wherein the machining tool is a laser.

28. The method according to claim 27, wherein the machining tool has a mass unbalance to generate the oscillation.
