Claims24
A building panel comprising a wood lamella core, a decorative surface layer on top of the core and balancing layer under the core, the core comprising several wood lamellas, which are stacked essentially parallel to each other in a stack, so that each of the wood lamellas in the stack extends in the same direction, and with long edge to long edge, and a long edge of a first wood lamella is arranged with a distance to a long edge of an adjacent second wood lamella in the stack,
- wherein the long edge of the first wood lamella is fixed by at least two distance elements to the long edge of the adjacent second wood lamella and at a first edge of the building panel, and
- wherein a first mechanical locking device is formed at the first edge of the building panel and at least partly in at least one of the distance elements.
A semi-product for a structural element or for a core for a building panel, the semi product comprising several wood lamellas, which are stacked essentially parallel to each other in a stack, so that each of the wood lamellas in the stack extends in the same direction, and with long edge to long edge, a long edge of a first wood lamella is arranged with a distance to a long edge of an adjacent second wood lamella in the stack, and the long edge of the first wood lamella is fixed by at least two distance elements to the long edge of the adjacent second wood lamella,
- wherein at least one of the distance elements is positioned at a short edge of the first and the second wood lamella.
A semi-product for a structural element or for a core for a building panel, the semi product comprising several wood lamellas, which are stacked essentially parallel to each other in a stack, so that each of the wood lamellas in the stack extends in the same direction, and with long edge to long edge, a long edge of a first wood lamella is arranged with a distance to a long edge of an adjacent second wood lamella in the stack, and the long edge of the first wood lamella is fixed by at least two distance elements to the long edge of the adjacent second wood lamella,
- wherein a third wood lamella is fixed to the second wood lamella by a third distance element, a fourth wood lamella is fixed to the third wood lamella by a fourth distance element, wherein one of the at least two distance elements, the third distance element and the fourth distance element are arranged in a straight line.
