A method of making a floorboard is disclosed. The floorboard comprises a mechanical locking system, a wood fibre based core and a surface layer arranged on the upper side of the core. The outer flat parts of the surface layer constitute a floor surface and a horizontal plane. The floorboard has an edge portion with an edge surface which is located under the horizontal plane. The method comprises applying the surface layer on the core to form a floor element, cutting the floor element into floor panels, applying a pressure on the surface of the edge portion of the floor panel, compressing the core under the surface layer, bending the surface layer permanently towards the rear side, forming an edge groove at the edge of the floor panel before applying the pressure, and forming the mechanical locking system at the edge of the floor panel after applying the pressure. |
