Definitions

  • the present invention relates to a panel for a piece of furniture, the panel having a core made of a wood-based material, the panel having a first and a second main surface and an edge which connects the two main surfaces, a covering layer being at least in sections on one or both main surfaces and where an edge coating extends over one or more edges, at least in regions, which partially or completely covers the edges.
  • Such a plate is known from the prior art.
  • the two main surfaces form the front and back or the top and bottom of the plate, between which a peripheral edge extends.
  • the two main surfaces are covered with a covering layer, e.g. can be a primer film to be coated or a decorative film that represents the final visible surface of the main surface.
  • a covering layer e.g. can be a primer film to be coated or a decorative film that represents the final visible surface of the main surface.
  • FIG. 1 shows the procedure known from the prior art for applying the edge coating.
  • the reference numeral 20 designates the above cover layer.
  • the edge surface (reference numeral 30) can be profiled, ie have a curve with which the edge surface 30 merges into the main surface ( Figure 2a) and 2b )) or have a chamfer, as shown in Figure 2c) and 2d ) is shown.
  • Figure 2a) and 2c ) shows the plate in a cross-sectional view before the edge coating is applied.
  • the present invention is therefore based on the object of providing a plate of the type mentioned at the outset in which this transition between the cover layer and the edge coating can be carried out absolutely straight. This object is achieved by a plate with the features of claim 1 and by a method with the features of claim 10.
  • the cover layer is designed with a fold, which is followed by the edge coating without joints.
  • the fold can be carried out absolutely straight by a removal process, which accordingly has the advantage that the transition between the top layer and the edge coating, i.e. the edge material is also straight and thus visually appealing.
  • a further advantage is that subsequent grinding of the edge material can preferably be dispensed with, since the fold creates a free space in which the edge material can be received in its edge region.
  • the edge coating is therefore preferably carried out in such a way that the edge coating closes continuously with the surface of the cover layer, i.e. neither protrudes nor is it set back from the top layer.
  • the fold can be designed in a step-like manner, the step having a flank that runs perpendicularly or obliquely relative to the main surface.
  • the step can thus be designed to run vertically or obliquely.
  • the fold can have a height that corresponds to or falls below the thickness of the cover layer of the main surface. In this case, only part of the top layer is removed to create the fold.
  • the fold has a height that is greater than the thickness of the cover layer and thus extends into the wood material.
  • the step of the fold extends over the entire thickness of the cover layer and also over part of the thickness of the wood material, which is also removed during the manufacture of the fold.
  • the edge coating can be designed as a filler in order to fill pores in the surface of the wood-based material, which is, for example, MDF, in the edge region covered by the filler.
  • the cover layer and / or the edge coating can be a primer layer, this primer layer being covered with at least one further coating which represents the visible surface.
  • the cover layer of the at least one main surface and / or the edge coating already represents the finished visible surface, i.e. is not covered with another layer.
  • the primer layer and / or the final surface and / or a layer located between them can be designed as a film and / or lacquer layer and / or as a layer containing metal particles, in particular as a lacquer layer containing metal particles.
  • Each of the layers of the plates according to the invention can be made in one or more layers.
  • the edge coating is preferably designed as a lacquer layer or other coating that is UV-hardenable or can be hardened by electron beam hardening, which is particularly advantageous if the lacquer layer contains metal particles, in particular metal powder.
  • edge itself and / or at least one layer located on it is profiled.
  • the present invention further relates to a method for producing a plate according to one of claims 1 to 9, wherein after the manufacture of the fold the edge coating is applied so that it is in the space created by the fold and joins seamlessly to the top layer.
  • the fold can be produced, for example, by a milling process.
  • the milling depth can be set so that only the edge area of the top layer facing the edge is removed or also part of the wood-based material.
  • the method is carried out in such a way that the top layer and / or the edge coating are not provided with a further coating, i.e. represent the visible area.
  • the invention also includes the case that the cover layer and / or the edge coating with a further coating, such as be provided with a layer of lacquer that represents the visible surface.
  • a further coating such as be provided with a layer of lacquer that represents the visible surface.
  • edge coating and / or a further coating of the edge coating are applied by a vacuum process or by a rolling process.
  • the edge coating is applied continuously, i.e. in a continuous process, it being conceivable that after coating one edge the coating is interrupted and then the coating of the next edge is continued and the corner areas are coated separately.
  • the entire edge including the corner areas, is provided with the edge coating in one step.
  • the edge coating and / or a further coating of the edge coating and / or the cover layer can be designed such that it can be cured by the action of UV light and / or by electron beam curing.
  • the latter method is particularly advantageous in the case when a lacquer layer is applied which is provided with metal particles, in particular with metal powder.
  • edge coating and / or a further coating of the edge coating forms a lacquer layer and / or is a layer enriched with metal powder.
  • the edge coating can be applied in an amount so that the edge coating with the top layer comprising the fold closes continuously or largely continuously, i.e. neither survives nor is set back in relation to this in the thickness direction of the coating.
  • Figure 1 shows with the reference numeral the plate 10 which forms the base body, ie the carrier plate of the plate 10 according to the invention.
  • the plate 10 consists of a wood material. Examples are MDF, particle board, plywood, solid wood, block board etc. or a combination of these.
  • the plate 10 has a first 101 and a second 102 main surface running parallel thereto, which are connected to one another by the peripheral edge 30.
  • a cover layer 20 on each of the two main surfaces 101 and 102, which e.g. can be designed as a primer film or as a cover film or as another primer or cover layer.
  • the cover layers 20 do not extend over the edge 30.
  • Figure 1a) and 1b ) show the plate with a curve in the transition area between the main surface and the edge and Figure 1c) and 1d ) show the plate with a chamfer in the transition area between the main surface and the edge.
  • the cover layer 20 can represent the final layer which is not provided with a further coating or also a primer layer, in particular film, which is provided with one or more further coatings.
  • FIG 3 shows a fold F (for example by milling or by another removal method) before the edge coating 30 is applied to the cover layer 20. introduced so that a step S is formed, the flank S1 of which is perpendicular to the main surface ( Figure 3a )) or sloping ( Figure 3b )) or set back diagonally ( Figure 3b )) can run.
  • a fold F for example by milling or by another removal method
  • the covering layer 20 or the wood material 10 is removed perpendicular to the plane of the paper and can be carried out absolutely straight, so that a step or a fold is formed which has a constant distance from the edge of the board over the entire edge length.
  • the thickness of the cover layer 20 can be, for example, 0.2 mm to 0.4 mm, preferably 0.3 mm. In the cases this corresponds to Figures 3a) to 3c ) then the level of level S.
  • the thickness 10 ' ie the thickness of the removed wood material to form the fold, is in the range from 0.05 mm to 0.15 mm, preferably 0.1 mm.
  • the edge coating 30 is applied by a suitable application process, so that the condition is in accordance with FIG Figure 1b) or 1d ) results.
  • the edge coating can be the final surface of the edge or a primer or a filler, which can then be provided with one or more other coatings.
  • the edge coating can be applied, for example, by a vacuum process or also by a rolling process.
  • the amount of edge material is preferably selected so that there is a continuous or essentially continuous transition between cover layer 20 and edge coating 40.
  • the material of the edge coating 40 can be, for example, a lacquer material or another layer (one or more layers) that can be applied as such or has one or more solid ingredients, such as e.g. metallic particles, such as metal powder.
  • the edge material is preferably applied in one pass, i.e. continuously with a drying device downstream of the order point.
  • the edge coating can be applied in such a way that the device for applying the edge coating is stationary and the plate is moved along the device or that the device is movable and moved along the stationary plate.
  • the plate can represent any part of a piece of furniture or form it, such as a cheek, front, rear wall of a cabinet Drawer, a worktop, a table top, a shelf etc.
  • the present invention also relates to a piece of furniture with at least one plate according to the invention. Edge coating
