Abstract

A method of producing a veneered element, including providing a substrate, applying a sub-layer on a surface of the substrate, applying a veneer layer on the sub-layer, and applying pressure to the veneer layer and/or the substrate, such that at least a portion of the sub-layer permeates through the veneer layer. Also, such a veneered element.

First claim

The invention claimed is:

1. A method of producing a veneered element, comprising:
providing a substrate,
applying a sub-layer on a surface of the substrate, the sub-layer being applied as a dry powder, the sub-layer comprising a binder and wood fibers,
applying a veneer on the sub-layer, the veneer being one of a wood veneer, a cork veneer, and a stone veneer, the veneer comprising a hole extending from the top surface through the bottom surface so that the sub-layer is visible through the hole of the veneer,
applying heat and pressure to the veneer and/or the substrate, the heat and pressure causing the sub-layer to melt and causing at least a portion of the sub-layer to permeate partially through the veneer to become visible at an upper surface of the veneer,
wherein the method further comprises
controlling a decorative design of the veneer by determining a level of partial permeation of the sub-layer through the veneer.

2. The method according to claim 1 wherein the substrate is a wood-based board.

3. The method according to claim 1 , wherein the veneer layer comprises a wood veneer.

4. The method according to claim 1 , wherein the veneer layer comprises a cork veneer.

5. The method according to claim 1 , wherein the veneer layer comprises a stone veneer.

6. The method according to claim 1 , wherein the binder is a thermosetting binder.

7. The method according to claim 1 , wherein the binder is a thermoplastic binder.

8. The method according to claim 1 , wherein after pressure has been applied, the veneer layer comprises embossed portions, wherein a portion of the sub-layer is more compressed under an embossed portion than under a non-embossed surface portion.
