Definitions

  • the invention relates to a method for manufacturing sheets of natural wood as well as natural wood sheets obtained by such a process, a decorative and / or utility article comprising such sheets of wood and the application of such sheets of wood and / or such articles to certain fabrications.
  • wood sheets according to the invention may be used more generally.
  • logs Currently, in the field of woodworking, it is known to use tree trunks, removing their ends and their bark to form pieces of wood, called logs.
  • the purpose of the present invention is to provide a method of manufacture of natural wood sheets which overcomes the aforementioned drawbacks and makes it possible to manufacture products with an indefinitely renewed decorative aspect, while limiting production costs.
  • Another object of the present invention is to provide a process for manufacturing natural wood sheets which limits the scrap and wasted raw materials.
  • Another object of the present invention is to provide a process for manufacturing natural wood sheets which optimizes the personnel and equipment employed.
  • the invention relates firstly to a method of manufacturing natural wood sheets.
  • a wooden ball 1 is provided, obtained from a tree trunk, with 2 wood defects, on the surface or even at its core.
  • wood species desired can be used. We could use, for example, birch, hornbeam, chestnut, oak, cypress, maple, fig, ash, beech, hackberry, hazel, walnut, olive, orne, poplar, pine, apple, fir, willow, mountain ash, lime tree or others.
  • said sheets 3 are cut from said ball 1 while retaining said faults 2.
  • the faultless parts 4 of the ball 1 of its faulty parts 5 It is thus possible obtain simultaneously, in the faultless parts 4, sheets of wood available for known applications such as plating, and, in parts with defect 5, sheets of wood available for new applications.
  • said separation prior to cutting said sheets 3 in particular by separating said balls into three parts, a central and two extremals, the defects generally being located in the extreme parts of the balls, then by cutting said end portions.
  • said cuts are cut. sheets of wood in ball 1 kept whole and, if necessary, separated the faultless parts of the faulty parts.
  • the cutting is carried out, by example, by slicing, that is to say, by cutting the ball 1 in planes parallel to the longitudinal axis of said ball 1, along the arrow marked 6.
  • FIG. 3 we performs the cut by unwinding, that is to say, by rotating the ball 1 around its longitudinal axis, according to the arrow marked 7.
  • the cutting means used for said peeling operation can possibly be tilted relative to the longitudinal axis of said balls. It will thus be possible to obtain sheets of wood having a substantially conical shape and / or frustoconical, particularly advantageous for making lampshades.
  • the cutting operations are carried out, possibly, on the back, that is to say on balls 1 previously cut radially, for example, in four parts.
  • said ball 1 Before cutting, said ball 1 can be hardened.
  • said sheets of wood 3 are, in particular, flattened, dried, cut and / or stacked. Their transportation will be ease.
  • trimming its role will be to equalize the edges of each sheet and not, as was the case in the previously known processes, to systematically eliminate the defects of the remaining wood.
  • the invention also relates to the natural wood sheets obtained according to the method described above. They may have a thickness, for example, of 5 to 10 tenths of a millimeter, in particular depending on the species of wood, for example 5/10 th , 6/10 th or 7/10 th of a millimeter.
  • the invention also relates to a decorative and / or utility article. made of such a sheet of wood and a sheet of attached support material on one of its faces. It could be, for example, a sheet of materials synthetic materials, such as, in particular, polyphane, fabrics or other materials. Said sheet is optionally transparent or translucent.
  • the invention also relates to an application of such sheets of wood and / or such articles in the manufacture of light screens. He will be able to be lampshades. Said sheets of wood may also be associated with a glass support behind which it will be possible to have a source luminous so as to constitute a decorative lamp.
  • said sheets of wood and / or said items are used as is. We can thus use their flexibility and transparency.
