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 4b overlaps the surface layer 31 that is substantially parallel to the horizontal plane of the first joint edge 4a 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′.

1. Floorboards provided with an upper decorative surface layer extending substantially in a main horizontal plane, said floorboards comprising a mechanical joint system at two opposite edges for locking together adjacent joint edges of two adjacent floorboards, wherein the decorative surface layer at a first joint edge and the decorative surface layer at a second joint edge overlap each other at the mechanical joint system at an overlapping part, said overlapping part is located below the main horizontal plane, and includes a first joint surface of the first joint edge facing a second joint surface at the second joint edge, the first joint surface and the second joint surface sloping away from the main horizontal plane such that the decorative surface layer at the first joint edge slopes directly from the main horizontal plane toward the second joint edge,wherein the decorative surface layer at the first joint edge extends along the first joint surface and the decorative surface layer at the second joint edge extends along the second joint surface. 2. Floorboards according to claim 1, wherein the decorative surface layer at the first joint surface and the decorative surface layer at the second joint surface are in contact. 3. Floorboards according to claim 1, wherein the first joint surface and the second joint surface are in contact with each other at the overlapping part. 4. Floorboards according to claim 1, wherein the mechanical joint system comprises a tongue which cooperates with a tongue groove for vertical locking and a locking element which cooperates with a locking groove for horizontal locking. 5. Floorboards according to claim 1, wherein the decorative surface layer is a laminate or wood veneer or comprises wood fibre mix, binders and wear resistant particles or a layer of paint. 6. Floorboards according to claim 4, further comprising a piece of flexible material disposed on either or both the tongue and tongue groove, which reduces movements between two mechanically joined floor panels in a vertical plane. 7. Floorboards according to claim 1, wherein the decorative surface layer adjacent to the first joint edge and the decorative surface layer adjacent to the second joint edge have substantially the same thickness as the decorative surface layer that is outside of the overlapping part. 8. Floorboards according to claim 1, wherein a core of the second joint edge overlapping the decorative surface layer at the first joint edge is thicker than the decorative surface layer at the first joint edge. 9. Floorboards according to claim 1, wherein the decorative surface layer is provided only on a top surface of the floorboards. 10. Floorboards according to claim 1, wherein a triangular recess is provided above the decorative surface at the overlapping part, and the decorative surface layer at the sloping first joint surface defines one side of the triangular recess. 11. Floorboards according to claim 1, wherein the first joint surface is longer than the second joint surface. 12. Floorboards according to claim 1, wherein the first joint surface and the second joint surface each consists of a single linear line. 13. Floorboards according to claim 1, wherein the decorative surface layer at the second joint surface intersects the decorative surface layer at the first joint surface. 14. Floorboards provided with an upper decorative surface layer extending substantially in a main horizontal plane, said floorboards comprising a mechanical joint system at two opposite edges for locking together adjacent joint edges of two adjacent floorboards, wherein the decorative surface layer at a first joint edge and the decorative surface layer at a second joint edge overlap each other at the mechanical joint system at an overlapping part, said overlapping part is located below the main horizontal plane, and includes a first joint surface of the first joint edge facing a second joint surface at the second joint edge, the first joint surface and the second joint surface sloping away from the main horizontal plane,wherein the decorative surface layer at the first joint edge extends along the first joint surface and the decorative surface layer at the second joint edge extends along the second joint surface,wherein a piece of moisture removal material is disposed on either or both the tongue and tongue groove in a vertical plane.
