Definitions

  • the present invention relates to a method of finishing wings made of faced wood and the wings produced by such a method.
  • faced wood is a wood consisting of chipboard panels such as the MDF (Medium Density Fibreboard) type to which a sheet or film of polymeric resin such as PVC or a sheet of paper impregnated with resins like melamine resins is applied.
  • MDF Medium Density Fibreboard
  • This polymeric or melaminic layer is generally carried out with imprints reproducing the typical nature of a type of wood, such as ash or walnut and the like. In this way the finished material is totally similar or even identical to real wood with the specific grain existing on it.
  • the wings suitable for instance to make doors or panels for wardrobes, shelves or pieces of furniture for various use generally consist of a rear plane on which a perimetral frame is applied, comprising wood boards properly called tablets, defining a central space generally called face.
  • these wings are made of solid wood, their grain both of face and tablets, are arranged in the longitudinal direction.
  • the vertical tablets have grain developing along the length and the transversal tablets have a cross grain, namely generally arranged in an almost horizontal direction.
  • the prior art shown in Fig. 1 provides for cutting the wing central face A to size, cutting separately the uprights B and the stringers C, then covering each piece by gluing under pressure the facing sheet, that is the polymeric PVC sheet or paper impregnated with melaminic resin.
  • the facing sheet of the prior art is already imprinted with the wood grain. Finally the elements are assembled so as to obtain the completed wing.
  • This process presently used involves application of the polymeric sheet on all the five pieces constituting the wing, therefore also on the portions that will be in contact with each other to form the wing frame.
  • This drawback causes a problem of aesthetic order because the crackings are not acceptable for quality and aesthetic reasons as well as a technical problem because said crackings may lead to passage of water that in turn may cause swelling or detachment of the tablets from the support.
  • the object of the present invention is to overcome the above mentioned drawbacks.
  • the invention aims at carrying out a method of producing wings of faced wood having vertical grain for the face and the tablets forming the vertical sides of the wing but horizontal grain for the tablets arranged transversally, in which presence of crackings between tablets or between tablets and base support are totally avoided.
  • the invention aims also at obtaining a saving of materials and in the production cycle of the wings, so as to decrease the manufacturing costs.
  • the cutting operation for the tablets may be carried out even after having applied to the tablets the layer of material provided with the relief grain, obtaining indeed the same result.
  • the application of a layer of material on the surface on sight of each tablet, whether made of wood or any other material having in any case imprinted the wood grain allows to obtain a visual effect fully identical to the effect that could be obtained if the tablet or the face of the wing would be made of real wood. Moreover a precise and quick assembly of the tablets constituting the wing frame is obtained.
  • the sheet of facing material such as a polymeric PVC sheet or a paper impregnated with melaminic resin so that the sheet may adhere without a break on the entire surface of the tablets and the support as well as on the wing edges. This occurs without any problem and above all without possibility of generating slits between tablets or between a tablet and the support plane of the wing.
  • the improvement of quality and appearance carried out by this method is clear.
  • the present invention relates also to the production of wings made by the above mentioned method.
  • FIG. 1 shows the construction of a wing according to the prior art
  • - Fig. 2 shows a wing assembled by the method of the invention before coupling the wing with the sheet of facing material
  • - Fig. 3 shows a wing tablet to which a strip of material having imprinted the typical grain of wood is applied.
  • the wing generally indicated with reference numeral 10, is made by cutting separately from raw material, such as chipboard, MDF or similar panels, the support plane 1 and the tablets 2, 3, 4, 5.
  • the support plane 1 generally has a greater thickness than the tablets.
  • a wing having a total thickness of 18mm consists of a support plane 14mm thick and tablets 4mm thick.
  • the tablets may indifferently be made of wood or of any other material such as plastics, metal and so forth.
  • strips of material having the wood grain are applied to the previously cut tablets.
  • a material may for instance be wood cuttings or even cardboard with imprinted wood grain or plastics and any other material having imprinted the wood grain.
  • Fig. 3 shows that a layer 21 of material is applied to the tablet 2, said layer in this case being cut wood blanks having a thickness of some tenths of millimeter.
  • this wood layer is carried out for instance by gluing under pressure. Then the tablet bearing the wood layer 21 is applied to the support plane 1 so as to make the wing as shown in Fig. 2.
  • the layer 11 is applied also to the face of the support plane, so that the entire surface of the completed wing has a surface roughness identical or totally similar to the wood grain.
  • wood grain is arranged longitudinally for the tablets 2 and 3 and transversally for tablets 4 and 5.
  • the tablet cutting operation may occur after the layer of material provided with grain is applied on a bar of MDF material or other suitable kind.
  • the sheet of facing material 6 is applied, for instance a PVC sheet, by the known method of application under temperature and vacuum so as to warrant a perfect adhesion of the sheet 6 on the surface on sight both of the wing and its side edges.
  • the sheet of facing material 6 is neutral, that is without imprints of wood grain, because the grain is already made on the assembled wing.
  • the wings may be provided with imprints of grain of various types of wood, such as ash, walnut, cherry tree, chestnut, pinewood, teak or other exotic woods.

Abstract

L'invention concerne un procédé de production d'ailes en bois revêtu présentant un plan support (1) fait d'une matière première telle qu'un aggloméré, un MDF ou un produit similaire, et plusieurs planches (2,3,4,5) formant un cadre sur ledit support. Le procédé consiste à couper aux dimensions le plan support et les planches adaptés pour recevoir le cadre de l'aile. Le procédé consiste ensuite à appliquer sur chaque planche et sur le plan support une couche d'une matière présentant un grain en relief d'un type de bois choisi; à assembler les planches de manière à obtenir une aile achevée; et à appliquer par encollage une feuille de revêtement sur la partie visible et les bords de l'aile.
