Definitions

  • the present invention relates to a method of manufacturing of a furniture panel of a wooden fibre material for making a curved furniture panel, where the panel is coated with a veneer layer at a first side and a plurality of grooves on the second side for facilitating the bending of the veneered fibre board into the curved shape, said grooves of a uniform depth leaving a thin bending layer of fibre material behind the veneer coating.
  • the invention further relates to a furniture panel in particular for a loudspeaker cabinet manufactured by such method.
  • the object of the invention is to provide a method and a panel which is more cost effective in its manufacturing and which ensures a satisfying accuracy of the grooves, so as to provide a curved panel in particular for loudspeaker cabinets in an inexpensive and reliable manner.
  • the invention also involves a furniture panel in particular for a loudspeaker cabinet manufactured by this method, whereby a panel according to the invention comprises the features of claim 9.
  • the first fibre board is a relatively thin fibre board which thereby is easily bendable to a convex or concave shape.
  • the grooves are cut. By gluing this grooved front side onto the second side of thin first fibre board it is assured that all the grooves end in the same distance from the veneered front side of the panel, so that a smooth curvature of the panel when it is bend.
  • This manufacturing process can be carried out with a high degree of automation which results in a cost efficient manner of producing curved furniture panels for e.g. loudspeaker cabinets.
  • the moisture degree in the panel can be kept under control, in particular during transport or storage.
  • the panel When the remaining layer on the second side of the second fibre board is at least partly removed, whereby the grooves are reopened, the panel is made ready for being bend in the sections where the groove covering layer is removed.
  • the removal of this layer only just before the actual bending operation is due, is advantageous in so far the panel is better protected against moisture during storage due to the smaller outer surface, and in that the panel can just as well be used for a planar furniture panel if the remaining layer is preserved.
  • the panel is fixed in its curved shape by adhesively joining the groove carrying second side of the curved panel to a front side of a further fibre board also provided with grooves and shaped in a matching curvature.
  • a light-weight furniture panel can be obtained, which also can be made self supporting.
  • the grooves are filled with a resilient material, preferably a sound absorbing foam material.
  • a resilient material preferably a sound absorbing foam material.
  • the second fibre board is provided with one or more groups of grooves, where said groups of grooves are separated by sections of regular fibre board.
  • a furniture panel can be produced which is designed for sectional curvature bending as well as corner bending, since it is possible to cut an almost penetrating V-groove in the back side of the panel.
  • the veneered top layer is given a finishing treatment prior to any possible subsequent bending of the panel. This means that no additional labour intensive surface treatment is required after the bending process.
  • first fibre board 3 having a first side 4 and a second side 5.
  • the first side 4 is provided with a top layer of veneer 2.
  • the second side 5 is jointed with a first side 7 of a second fibre board 6 which is provided with grooves 8 that are cut out in this second board 6.
  • the grooves 8 are all cut in parallel and orientated perpendicular to the curvature. By the cutting of the grooves 8 a number of strips 10 are build in the second fibre board 6 just as a through-going remaining layer 9 of the fibre board 6 is preserved.
  • a thin sheet 13 is provided on the rear side of the second fibre board 6 .
  • This sheet is preferably of a vapour impenetrable material, so as to maintain a stabile moisture content in the fibre boards 3, 6 of the panel 1 during storage and transportation.
  • the veneer layer 2, the first fibre board 3, the grooved second fibre board 6 and the protecting sheet 13 are adhesively jointed together as shown in figure 2 in a single pressing operation.
  • the furniture panel 1 as shown in fig. 2 is well suited for storage under normal storage conditions, whilst awaiting the bending operation
  • the remaining, preserved layer 9 is removed, as shown in fig. 3, reopening the grooves 8 in the other end as they previously were.
  • the remaining of the second fibre board 6 is hereby only the strips 10 - at least in the sections that are being prepared for curvature bending.
  • a furniture panel 1' ready for curvature bending is shown, where the grooves 8 are filled with a resilient material 12, such a damping foam material.
  • a resilient material 12 such as a damping foam material. This material can either be applied after the rear layer 9 of the second fibre board 6 is removed or prior to the assembly of the panel 1, i.e. during the preparation of the second fibre board 6.
  • the second fibre board 6 is provided with groups 11 of grooves 8, and between the said groups 11 are built sections 14 of regular fibre board that are uncut. If necessary a V-groove 15 can be cut in such a section 14 as shown in fig. 7, so that a corner folding and also a panel curving can be carried out with a furniture panel according to the invention
  • a curved panel 1'' is shown where it is fixed in its curved shape by use of another grooved fibre board 12 that, similar to the second fibre board 6, is provided with grooves 8 and strips 10.
