Definitions

  • This invention relates to a method for providing a laminated board, and a method for manufacturing a furniture element. Moreover, this invention relates to a laminated board and a furniture element comprising such laminated board.
  • low weight elements are widely used. Such elements usually consist of a hollow body enclosing a lightweight filling material. The hollow body is covered by a thin film for increasing the aesthetic impression as well as for providing a protective coating for the element.
  • Such low weight elements can be used as construction elements, door panels, and a large amount of furniture elements. Especially in case of home interior applications, heavy demands are made on the thin film. Any damage or degeneration will deteriorate the quality of the low weight element. Consequently, a number of manufacturing methods for such low weight elements have been presented.
  • the European patent EP 1,492,663 describes a hollow sandwich panel having a body clad externally by sheets, each sheet being composed of a structural layer and of an external lamina that has a predominantly aesthetic function.
  • the sheets comprise contoured incisions at which folds are formed in order to make said sheets follow the discontinuities of the body and/or other discontinuities, said incisions associated with convex folds being formed on the side of said layer through its entire depth.
  • the external lamina is used as a hinge when the sheets are folded.
  • the hollow sandwich panel results in folding edges having a very uneven surface, or even cracked edges. This affects the quality of the hollow sandwich panel severely.
  • Another problem with the hollow sandwich panel is that the folding edges must be grinded, which result in an additional manufacturing step, thus increasing the manufacturing costs.
  • the manufacturing method of the hollow sandwich panel according to EP 1,492,663 requires the application of an auxiliary tape for enabling and ensuring that the edges of the final product are held together. This is due to the fact that the V-shaped incision, allowing the folding of the sheet, most certainly damages the lamina, and that the folding of the sheet stretches - and thereby strains - the lamina.
  • an improved low weight element for furniture manufacturing would be advantageous, as well as an improved method for manufacturing such low weight element.
  • the present invention preferably seeks to mitigate, alleviate or eliminate one or more of the above-identified deficiencies in the art and disadvantages singly or in any combination and solves at least the above-mentioned problems by providing a method and a device according to the appended patent claims.

  • a method for providing a laminated board material comprising a board material having a first side and a second side.
  • the method comprises arranging a first longitudinal groove on said first side of the board material, applying a laminating foil on said first side of said board material, said laminating foil is covering said first groove, and arranging a second longitudinal groove on said second side of said board material, said second groove is extending through said board material to connect with said first groove.
  • the method comprises the method for providing a laminated board material according to some embodiments, arranging a supporting structure at the second side of said board material by means of a fastening means, and folding said board material along a first and second set of said first and second grooves, respectively, such that the supporting structure is enclosed within said board material.
  • a laminated board for use in furniture elements comprises a board material having a first side and a second side, a first groove provided on said first side of said board material, and a second groove provided on said second side of said board material.
  • the laminated board is characterized in that a laminating foil applied on said first side of the board material and covering said first groove, and said second groove is extending through said board material to connect with said first groove.
  • a furniture element comprising a laminated board according to some embodiments is provided.
  • the furniture element further comprises a supporting structure arranged on said second side of said board material by means of an adhesive, wherein said laminated board is folded along a set of first and second grooves such that the supporting structure is enclosed within said board material.

Le procédé comporte les étapes consistant à réaliser une première rainure sur ladite première face du matériau pour planches, à appliquer une feuille à stratifier sur ladite première face dudit matériau pour planches, ladite feuille à stratifier recouvrant ladite première rainure, et à réaliser une deuxième rainure sur ladite deuxième face dudit matériau pour planches, ladite deuxième rainure s’étendant à travers ledit matériau pour planches de façon à rejoindre ladite première rainure. On décrit également une planche stratifiée destinée à être utilisée dans des éléments d’ameublement. La planche stratifiée comprend un matériau (10) pour planches présentant une première face et une deuxième face, une première rainure (20) réalisée sur ladite première face dudit matériau (10) pour planches et une deuxième rainure (22) réalisée sur ladite deuxième face dudit matériau (10) pour planches. La planche stratifiée est caractérisée en ce qu’une feuille (12) à stratifier est appliquée sur ladite première face du matériau (10) pour planches et recouvre ladite première rainure (20), et en ce que ladite deuxième rainure (22) s’étend à travers ledit matériau (10) pour planches de façon à rejoindre ladite première rainure (20).
