Abstract

A floor panel with a substrate and a top layer of laminate, which floor panel, at one or more edges, is provided with a lower edge region, wherein the laminate extends in one piece from the actual upper surface of the substrate over the lower edge region at least up to a point, wherein the laminate surface is situated at a level in a horizontal plane which intersects the substrate, and that the substrate material, at the location of the lower edge region, has the same or a lower density than at the actual upper surface of the substrate material. The invention also relates to a method for realizing such floor panels.

First claim

The invention claimed is:

1. A floor panel comprising:
a substrate and a top layer of laminate,
wherein said floor panel, at one or more edges, is provided with a lower edge region in the form of a bevel or other chamfer,
wherein said laminate extends in one piece from an actual upper surface of the substrate over a lower edge region at least up to a point,
wherein the laminate surface is situated at a level in a horizontal plane which intersects the substrate, and the substrate material, at a location of the lower edge region, has the same or a lower density than at the actual upper surface of the substrate material,
wherein the substrate substantially consists of an HDF board having an average density of more than 800 kilograms per cubic meter, wherein said HDF board forms at least said actual upper surface of the substrate and the substrate surface at the location of the lower edge region,
wherein the laminate is formed on the basis of a melamine resin and one or more paper sheets,
wherein the laminate comprises at least a printed and resin-provided paper sheet and wear-resistant particles located above the print,
wherein the laminate is adhered to the substrate without any intermediate glue or resin layers, both on the actual upper surface and at the location of the lower edge region, and
wherein the printed and resin-provided paper sheet at least partially contacts the substrate.

2. The floor panel according to claim 1 , wherein the surface of the lower edge region is made sloping and this slope encloses an angle of more than 30° with the actual upper surface.

3. The floor panel according to claim 2 , wherein the sloping surface of the lower edge region extends up to the actual edge of the floor panel.

4. The floor panel according to claim 1 , wherein the level of the laminate surface slopes continuously from on the upper surface onto the lower edge region.

5. The floor panel according to claim 1 , wherein the depth to width ratio of the lower edge region is at least 0.60.

6. The floor panel according to claim 1 , wherein the floor panel comprises such lower edge regions on at least two opposite edges, wherein the respective point up to which the laminate surface is extending is situated in both lower edge regions at an equal horizontal level or practically equal horizontal level wherein a possible difference in horizontal level is less than the thickness of the laminate.

7. The floor panel according to claim 1 , wherein the substrate has a density at the actual substrate surface of more than 900 kilograms per cubic meter.

8. The floor panel according to claim 1 , wherein said resin-provided paper sheet is provided with the melamine resin.
