Such a generation of a function fi lm can take place in the context of the already described color matching.
  • a specified hue is generated by combining at least two color function films.
  • Such additive generation of a hue can for example be based on known color models, such as RGB or CMYK.
  • the adjustment of the color of the joint area is supported by the fact that upon activation of the color function films combined together they fuse together and thus form a uniform hue.
  • the functional film is preferably designed such that it absorbs the color, ie that it is evenly distributed over the thickness ofjansfi1ms. Also, a uniform distribution injansfiIm or in the entire synthesis element by an activation device 22, 30, 31 are supported.
  • a metal layer may be used.
  • a functional film for coloring for example, it is possible to use an absorbent layer of wood fibers.
  • Another task of the functional films 11, 12, 13 may be to adapt the connection between an edge material 3 and the workpiece 1 to their properties.
  • the edge material materials which are generally of little receptivity are concerned
  • the narrow surface of a workpiece 1 may consist of a material which has a high absorption capacity, for example because of its porosity.
  • Adhesives with which a bond is possible, so that a zero joint over a particularly narrow joint area (about 0.2mm) is generated, tend to be thin liquid in the activated state. On the one hand, this results in a uniform, thin distribution of the adhesive or adhesive, but on the other hand also leads to a slight penetration of the adhesive into an absorbent material of a bonding partner.
  • the coating device according to the invention has the advantage that it can be used to produce a more cost-effective adhesive composite which forms or is integrated in the synthesis element 10.
  • a two-component adhesive system can be used for bonding, which, as already described above, consists of at least one functional film 11, 12, 13.
  • a two-component adhesive system can be used for bonding, which, as already described above, consists of at least one functional film 11, 12, 13.
  • fillers and absorbent materials can be reliably connected to the edge material 3.
  • the adhesive functional film 11 provided for the zero joint it is possible in this context for the adhesive functional film 11 provided for the zero joint to be applied to a carrier functional film 12 which, when the edge material 3 is brought together with the workpiece 1, connects the same.
  • the adhesive function film 11 faces or joins the bonding surface having the lower absorbency.
  • the carrier function film 12 faces the bonding surface, which has the higher absorbency.
  • the activatable carrier function film 12 upon activation of the activatable carrier function film 12, it fills the pores of the absorbent workpiece 1, resulting in lower adhesive loss in the adhesive function film 11. Consequently, the bonding between the edge material 3 and the workpiece 1 is improved while saving the more expensive adhesive used in the adhesive function film 11.
  • Coating device is designed with the devices described above.
  • the joint area between the edge material 3 and the workpiece 1 becomes visually and structurally to the quality requirements of the product to be produced customized. The result is less waste, a higher producible variety and a better aesthetic result.

Abstract

La présente invention concerne un procédé d'assemblage d'une surface d'assemblage (5) d'un matériau de chant (3) avec la surface d'assemblage (2) d'une pièce (1) par l'intermédiaire d'un élément synthétique (10). Le procédé comprend les étapes suivantes : production de la pièce (1), acheminement de l'élément synthétique (10), lequel est produit par au moins un film fonctionnel (11, 12, 13), au moins un film fonctionnel (11, 12, 13) étant constitué d'un adhésif, activation du film fonctionnel adhésif (11), application de l'élément synthétique (10) sur l'une des surfaces d'assemblage (2, 5), assemblage de l'élément de synthèse (10) avec l'autre des surfaces d'assemblage (5, 2) de sorte que la pièce (1) et le matériau de chant (3) soient assemblés l'un avec l'autre par l'intermédiaire de l'élément synthétique (10) qui se trouve entre eux. La présente invention concerne en outre un élément synthétique (10) et un dispositif d'assemblage d'une surface d'assemblage (5) d'un matériau de chant (3) avec la surface d'assemblage (2) d'une pièce (1).
