  • Publication number: 20210379907
    Abstract: A method and equipment to form a digital print by applying dry colourants on a surface of a panel, bonding a part of the colourants with a binder and removing the non-bonded colourants from the surface. The method of forming a digital print on a surface of a panel includes displacing the panel under a digital drop application head, applying a liquid binder with the digital drop application head on the surface; applying colourants on the liquid binder and the surface; bonding a part of the colourants to the surface with the liquid binder; removing non-bonded colourants from the surface such that a digital print is formed by the bonded colourants; and applying heat and pressure on the panel, the surface and the bonded colorants such that the colourants are permanently bonded to the surface.

  • Patent number: 11130325
    Abstract: A method for forming of a building panel with a surface including a thermosetting resin such that tension created during curing of the surface is reduced or eliminated. Method for producing a panel with a wood based core and a surface layer including a thermosetting resin wherein the method including: curing and connecting the surface layer to the core while applying heat and pressure in a first main pressing step, thus raising a temperature of the surface layer above an initial temperature; applying a bending force on the panel after the first main pressing step to bend the panel such that an uppermost surface of the panel is convex an a lowermost surface of the panel is concave while the panel is still above the initial temperature; and releasing the bending force such that the panel springs back to an essentially flat shape.
