Definitions

  • the invention relates to a plate with a postforming edge according to the preamble of patent claim 1.
  • Chipboard or MDF or plywood is used as the board material for this.
  • EP-A-0 458 242 also exposes the coating by removing chips from the plate.
  • a fillet is then milled on the front edge of the fold in the transition area between the front edge of this fold and the coating that has remained. Then the front edge is machined in the later desired radius of the postforming edge.
  • a hot-melt adhesive is then poured into the previously milled fillet, and the plastic material of the remaining coating is deformed under pressure and heat, so that it is pulled over the radiused end edge of the fold and a so-called postforming edge is thereby achieved.
  • postforming edges had only been produced with relatively rigid, inherently stable plastic coatings, because these plastic coatings withstand the high heat loads required during the deformation and because they have good surface resilience, which has the advantage that the production of the postforming edge without tearing the plastic material or otherwise Damage was made possible.
  • the invention is therefore based on the object of developing a plate of the type mentioned in such a way that a postforming edge can be formed in a cost-effective manner with a wood-based material or a faux-paper or foil-based decor.
  • the invention is characterized by the technical teaching of claim 1.
  • the process for producing a postforming edge was known only with relatively rigid, inherently stable plastic laminates, this laminate being exposed by milling.
  • the coating carrier is also milled in order to form this coating carrier together with the coating as a postforming edge.
  • such a postforming edge can now also be formed from a thin wood material, for example a wood veneer (peeling or knife veneer).
  • a wood veneer is a coated veneer, which consists of a decorative layer made of real veneer, which is glued to a carrier material made of tissue, paper, PVC, thin paper or the like.
  • the present invention comprises so-called MDF boards with a decorative coating, which consists of a paper or PVC material.
  • a postforming edge is also formed here, the MDF board consisting of wood fibers in connection with the decorative coating above is reshaped according to the invention.
  • panels made of plywood material, MDF or chipboard or panels with hollow structures are preferred, which contributes to a substantial saving in weight.
  • Such hollow structures essentially consist of strips which form a peripheral frame, this frame defining a central, central cavity, and this frame being covered on both sides (top and bottom) by the wood-based material.
  • a plate 1 is shown in FIG. 1 a, which can consist of an MDF material, a chip fiber material or a plywood material.
  • the plate 1 has on its top 3 a coating 2, which is also attached to the bottom 4.
  • the coatings 2 are e.g. thin film-like surfaces which can be connected to the surface of the plate 1 in the lamination process.
  • a fold 5 is first milled into the material of the plate 1 from the top 3 of the plate 1, the overlying coating 2 also being removed in this area.
  • the fold depth of the fold 5 is now increased, so that the section which remains has only a thin material layer as the coating carrier 6 and a coating 2 forming the underside 4.
  • the material layer 6 serving as the coating carrier is formed from the material of the plate 1 that has remained in order to give the coating 2 on the underside 4 the mechanical stability necessary for the subsequent forming.
  • a rounding 7, which is designed as a groove 13, is milled in the area of the transition on the end face 21 of the fold 5 in the direction of the remaining material layer of the coating carrier 6.
  • this rounding 7 is deepened and enlarged by a groove cutter 8 which is subsequently moved up.
  • a fold 9 is then milled into the upper side 3, which has a depth that corresponds to the thickness of the material of the coating together with the coating carrier 2, 6.
  • the end face 21 of the fold 5 is machined and a radius 10 is formed in order to achieve the later shaping of the postforming edge.
  • FIG. 2 shows the conditions according to the innovation enlarged on average.
  • the material layer of the coating carrier 6 is formed from the material of the plate 1 and supports the coating 2 during milling, and that a hot melt adhesive 14 has now been poured into the area of the fillet 13 in order to ensure a smooth and smooth transition in this Ensure area.
  • the coating carrier 6 consists of the wood material of the plate 1, as was defined in the manner above. That means it is a wood veneer (peeled or knife veneer), chipboard hardboard, plywood or MDF. If the outer layer of the plate 1 consists of a wood veneer, then the coating carrier 6 is part of the plate 1 and can also be connected to paper, tissue, etc. for stabilization.
  • the material layer of the coating 2 and the coating carrier 6 produced in this way is bent in the direction of the arrow 15 in accordance with FIG.
  • glue is applied to the inside of the material layer of the coating carrier 6 in order to ensure gluing on the rounded end face 21.
  • the material is now bent over and thus forms the postforming edge according to the invention, which is now formed for the first time from a composite of a wood material as a coating carrier 6 with any top layer as a coating 2.
  • the coating 2 is sucked onto the processing table by applying a vacuum in order to stabilize this coating surface.
  • the thickness of the material layer 6 very small, e.g. in the range of 0.1 to about 1 mm.
  • FIG. 4 shows a construction of a plate according to the invention, it being essential that this plate is designed as a hollow plate for reasons of weight saving.
  • the coating 2 consists of a very thin decorative paper, which is printed, for example, with a wood grain, a plain color or any other color.
  • This coating 2 is glued to a veneer layer 17, which veneer layer 17 can consist, for example, of a three-layer plywood material in a manner known per se.
  • this can consist of an MDF material or of a thin chipboard or hardboard.
  • the veneer layer 17 consists of three layers 22, 23, 24 glued shut off to one another.
  • veneer layer 17 is thinned in such a way that only the cover layer 22 serving as the coating substrate, which is directly adjacent to the thin coating 2, also runs around the postforming edge 16, while all other layers 23, 24 in Area of the top 3 of the plate 1 remain.
  • the very thin coating 2 is thus only supported by the cover layer 22 and is thereby stabilized in the area of the postforming edge 16.
  • the frame consisting of strips 19, 20.
  • two strips 19, 20 have been glued to one another and that the outer strip 20 has the machined end face 21 in each case.
  • the strip 19, 20 may consist of a single piece.
  • the strips 19, 20 form a frame-like structure with the formation of a central cavity 18 so as to greatly reduce the weight of the entire plate.
  • FIG. 4 the upper part of the plate is now shown in FIG. 4, the plate being able to be continued beyond the line of symmetry.
  • an L-shaped postforming edge is then formed or a U-shaped postforming edge is formed, as is shown in FIG. 3.
