Abstract
A method for manufacturing 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, where 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. 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.

A method for manufacturing floor panels, wherein these floor panels comprise at least a substrate and a top layer of laminate and 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 the method comprises at least the following steps:
- providing a basic board of the material of the substrate and of structuring an upper surface of said basic board, wherein the structure consists at least of a recess in the upper surface of the basic board at a location of said lower edge region;
- composing a stack which comprises at least the structured basic board and one or more melamine resin layers and possibly paper layers;
- pressing said stack in a heated press, wherein said melamine resin hardens and, together with the possible paper layers, forms a laminate layer adhered to the substrate, and wherein the laminate layer extends in one piece from the upper surface of the basic board up to into said recess, at least up to a point, wherein the laminate surface is situated at a level in a horizontal plane intersecting the substrate;
- subdividing the pressed whole into panels, of which said floor panels can be formed;
- and
- finishing the panels to form said floor panels, wherein an edge of said recess forms the lower edge region.
