Definitions

  • the present invention relates to a method of fixing a sheet of wood on a rigid object and, more precisely, inside a champlevé formed on a metal object.
  • glues with high elongation coefficients are generally used for gluing wood sheets such as, for example, glues of the neoprene type.
  • the sheet of wood is arranged inside a champlevé, that is to say in a recess formed on the surface of the support (for example FR-A Nos 251620 and 614319).
  • a champlevé that is to say in a recess formed on the surface of the support (for example FR-A Nos 251620 and 614319).
  • the surface of the same also tends to increase and, being prevented by the edges of said champlevé, it will then bulge or warp.
  • this type of deformation generally results in partial peeling of the sheet.
  • So-called bakelized wood was thus prepared, by impregnating the interior of the fibers, as well as the interfiber spaces, with a phenol / formaldehyde resin in alcoholic solution.
  • the wood thus treated has a great insensitivity to hygroscopic variations, as well as improved mechanical characteristics.
  • the present invention aims to remedy these various drawbacks.
  • a method of fixing a sheet of wood inside a champlevé formed in a rigid support this method being characterized in that it comprises at least the following successive phases: a partial impregnation of the wood sheet, from one of its faces, with a hardenable resin; a bonding operation of said sheet by its face previously impregnated with resin inside the champlevé, and a surfacing treatment intended to make the edges of the champlevé and the surface of the wood flush, by thinning the wood sheet and simultaneous machining edges of the champlevé.
  • This process thus makes it possible, while stabilizing by impregnation, in a known manner, the sheet of wood with respect to humidity variations, to preserve on its surface its appearance of natural wood. Indeed, during the surfacing treatment which follows the bonding phase and which affects only a small thickness of the wood sheet, the natural wood remains apparent, if care is taken during this operation to not not reach the resin impregnated part from the other side.
  • the present method makes it possible to avoid the delicate adjustment operation necessary for flushing the surface of the wood with the edge of the champlevé since, during the surfacing operation, wood and edges of the champlevé are machined simultaneously. .
  • the licensee implemented this process to apply, as a decorative element, a sheet of wood on a lighter.
  • each of the faces of the lighter intended to receive a sheet of wood has been hollowed out with a champlevé to a depth of 0.5 mm.
  • the wood sheets in this case consisting of elm burl, were then partially impregnated by coating with a 50% solution of epoxy resin in methyl ethyl ketone. They were then dried for 15 min in an oven, at a temperature of 90 ° C. The dried sheets, with a thickness of 1 mm, were then cut by different shape tools, that is to say tools having the exact shape and lateral dimensions of each of the edges of the champlevé.
  • the controlled impregnation of the wood sheets with a hardenable material prior to their cutting makes it possible to prevent them, during this operation, from splitting or tearing.
  • the sheets thus cut because of their insensitivity to variations in humidity, can be stored easily, pending their bonding.
  • resins capable of impregnating the wood sheet and, optionally, of sticking it to the champlevé it is also possible to use, inter alia, a polyurethane resin, diluted for example in toluene, at the rate of two parts by weight of polyurethane for a part of toluene, or also a polyester resin, diluted for example in monomeric styrene, at a rate of three parts of polyester for a part of styrene.
