Semi-floating floorboards/building panels having mechanical joint systems, a core with curved edge portions so the surface layer on top of the core will be located below the panel surface, and where the edges of the floorboard have a bevel such that in which the joint system, when two floorboards are joined and pressed towards each other, the surface layer 31 and a part of the core 30 of the joint edge portion 19 in the second joint edge 4 b overlaps the surface layer 31 that is substantially parallel to the horizontal plane of the first joint edge 4 a of the other floorboard. Further, floorboards/building panels are produced by machining the surface structure with a plurality of core grooves 20, 20 ′ and applying the surface layer 31 on the upper side of the core 30 to at least partly cover a floor element. A pressure is applied and the surface layer 31 forms around the core grooves 20, 20′. |
