Abstract

A process for producing a decoration, in particular a wood decoration, and a relief, corresponding to the decoration, on the top side of a woodbased-material board which is pressed in a press, by means of a pressing plate, with a cover layer made of a synthetic resin, in particular a paper layer impregnated with melamine resin, which has been applied to the top side of the woodbased-material board, the relief being stamped, during the pressing operation, by a female die which interacts with the pressing plate, is distinguished in that the decoration and the relief are introduced simultaneously into the cover layer.

Claims

1. A process for producing a decoration and a relief, corresponding to the decoration, at least on a top side of a woodbased-material board which is pressed in a press, by means of a pressing plate, with a cover layer of a synthetic resin which has previously been applied to the top side of the woodbased-material board, the relief being stamped, during the pressing operation, by a female die which interacts with the pressing plate, characterized in that the decoration and the relief are introduced simultaneously into the cover layer.

3. The process according to claim 1, wherein the decoration is a wood decoration.

4. The process according to one of claims 1, wherein the female die is coated with ink before the pressing operation and the decoration is produced by the relief being provided with color.

5. The process according to claim 4, wherein the ink binds with the synthetic resin during pressing of the cover layer.

6. The process according to claim 1 wherein a single-colored paper layer is applied to the top side of the woodbased-material board, and a cover layer of synthetic resin is applied to the paper layer.

7. The process according to claim 1, wherein the top side of the woodbased-material board is provided with color before the cover layer is applied.

8. The process according to claim 7, characterized in that a layer of ink is applied.

9. The process according to claim 1, characterized in that a multi-colored paper layer is applied to the top side of the woodbased-material board.

10. The process according to claim 9, wherein a cover layer of synthetic resin is applied to the paper layer.

2. A process for producing a decoration and a relief, corresponding to the decoration, at least on a top side of a woodbased-material board which is pressed in a press, by means of a pressing plate, with a paper layer which is impregnated with melamine resin and has been applied beforehand to the top side of the woodbased-material board, the release being stamped, during the pressing operation, by a female die which interacts with the pressing plate, characterized in that the decoration and the relief are introduced simultaneously into the cover layer.

15. The process according to claim 2, wherein the decoration is a wood decoration.

16. The process according to one of claim 2, wherein the female die is coated with ink before the pressing operation and the decoration is produced by the relief being provided with color.

17. The process according to claim 2, wherein a single-colored paper layer is applied to the top side of the woodbased-material board, and a cover layer of synthetic resin is applied to the paper layer.

18. The process according to claim 2, wherein the top side of the woodbased-material board is provided with color before the cover layer is applied.

19. The process according to claim 2, wherein a multi-colored colored paper layer is applied to the top side of the woodbased-material board.

11. A board made of a woodbased material, with a top side provided with a decoration and a relief which is stamped into a layer of synthetic resin, characterized in that the decoration is formed by ink introduced into the structure of the relief.

14. A board according to claim 11, wherein the decoration is a wood decoration.

20. The board made of wood based material of claim 11, comprising one of MDF and HDF.

12. A board made of a woodbased material, comprising Medium Density Fiber (MDF).

13. A board made of a woodbased material, comprising High Density Fiber (HDF).
