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 comprising a binder and a filler,
applying a veneer on the sub-layer, the veneer comprising porous portions and non-porous portions, and
applying heat and pressure to the veneer and/or the substrate, the heat and pressure causing at least parts of the sub-layer to melt and causing at least a portion of the sub-layer to permeate partially through said pores of the veneer such that the binder of the sub-layer bonds the porous portions of the veneer in a compressed position to form embossed portions, and wherein the binder does not bond the non-porous portions of veneer in the compressed position so that the non-porous portions of the veneer form protrusions after pressing.

2. The method according to claim 1 , wherein the sub-layer is applied as a dry powder.

3. The method according to claim 1 , wherein the sub-layer is applied in liquid form.

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

5. The method according to claim 1 , wherein the veneer comprises a wood 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 said filler comprises particles or fibres selected from the group of: cork, barium sulphate, lignocellulose, cellulose, starch, rice, straw, corn, jute, linen, flax, cotton, hemp, bamboo, bagasse, and sisal.

9. The method according to claim 1 , wherein the heat and pressure are applied for 30 seconds or less.

10. The method according to claim 1 , wherein the heat and pressure are applied in a short cycle press.
