Definitions

  • An object of the invention is to allow the production of solid wood panels in a wide range of thicknesses.
  • the exterior plies may consist of one or more decorative wood veneers sliced or peeled to form decorative plywood panels.
  • the state of the art provides, for these actors of the second and third transformations of wood, the plywood panels briefly described above, or particle boards, rich in glue, high density particle boards or so-called reconstituted wood panels.
  • the method also comprises a second cutting step, after the steaming step, to form logs having a final length of between 120 cm and 135 cm, the first cutting resulting in forming logs having a length equal to an integer multiple greater than or equal to 2 of said final length of said logs.
  • the method comprises, after the edging step, a sanding step to improve the surface quality of said multi-layered solid wood panels.
  • the method further comprises a step of painting the multilayer solid wood panels and / or a varnishing step of the wood panels.
  • An advantage of the process according to the invention lies in the fact that the multi-layered solid wood panels thus produced have a solid wood appearance: strata are not seen because the wood fibers of adjacent veneers glued together are connected.
  • the process according to the invention allows the production of semi-finished multilayer solid wood panels from raw wood, in particular in size ranges ranging from 6 mm to 48 mm in thickness for approximately 1.2 m in width and approximately 2 m. , 3 m in length.
  • first and second cutting 2, 4 there may be only one sectioning, before steaming 3, to directly produce logs having the desired final size, typically between 1.2 m and 1. , 35 m.
  • a first sectioning 2 is preferably envisaged, after debarking 1 and before steaming 3, to form ridges having a length equal to an integer multiple greater than or equal to 2 of the length of. final ridge desired.
  • a second sectioning 4 is provided, after steaming 3, to produce the logs having the desired final length.
  • the unwinding thus makes it possible to produce long veneers of reduced thickness, between 1 mm and 10 mm, preferably equal to 3.2 mm, and of width equal to the width of the bales, i.e. between 1.2 m and 1, 35 m preferably.
