Claims27
A method of producing a building panel with a curved edge portion, the building panel including a wood-based core and a decorative surface, wherein the decorative surface comprises a wood veneer or a paper laminate layer, the method comprising:
- heating an edge of a building panel;
- lubricating a press tool at an exterior surface of the press tool that is configured to compress the edge of the building panel, with an oil or grease;
- and
- after lubricating, compressing the edge of the building panel with the press tool to a curved edge shape so that at least the core at the edge of the building panel has a curved shape, wherein the edge of the board is compressed more than 0.5 mm, and wherein said compressing step compresses both the decorative surface and the core.
A method of producing a building panel with a curved edge portion, the method comprising:
- heating an edge of a building panel;
- lubricating a press tool;
- and
- after lubricating, compressing the edge of the building panel with the press tool to a curved edge shape,
- wherein the building panel comprises a decorative surface and a wood-based core, and wherein the decorative surface comprises a wood veneer, and
- wherein said compressing step compresses both the decorative surface and the core so that the core and the decorative surface have a curved shape, and wherein the decorative surface extends to an outer edge of the curved edge shape at the curved edge portion.
A method of producing a building panel with a curved edge portion, the method comprising:
- heating an edge of a building panel;
- lubricating a press tool at an exterior surface of the press tool that is configured to compress the edge of the building panel, with an oil or grease, the press tool having a surface that is grinded to a roughness of about 0.2 Ra;
- and
- after lubricating, compressing the edge of the building panel with the press tool to a curved edge shape,
- wherein the building panel has a planar surface, including the edge portion, prior to compression, and wherein the step of compressing the edge of the building panel with the press tool involves compressing the entire edge portion from the plane of the planar surface to the curved edge shape,
- wherein the building panel comprises a decorative surface and a wood-based core, the core being compressed to have a curved shape by the press tool,
- wherein the decorative surface comprises a wood veneer or a paper laminate layer comprising a resin, and
- wherein the decorative surface extends to an outer edge of the curved edge shape at the curved edge portion.
A method of producing a building panel with a curved edge portion, the method comprising:
- heating an edge of a building panel;
- lubricating a press tool;
- and
- after lubricating, compressing the edge of the building panel with the press tool to a curved edge shape,
- wherein the building panel comprises a decorative surface of wood veneer or paper laminate and a wood-based core,
- wherein the decorative surface extends to an outer edge of the curved edge shape at the curved edge portion, and
- wherein the core at the edge of the building panel is compressed by the press tool to have a curved shape.
