Definitions

  • the invention relates to a method for the production of wood elements with a natural wood grain replica drawing, wherein a plurality of thin rectangular peeled veneer layers are stacked and bonded under pressure between the male and gegen Dermaer die of a press to coincident curved Operapreßlingen, which then superimposed form-fitting and with the interposition of binder pressed to the compact, after which the wood elements are separated from the compact layer by layer.
  • first veneer sheets are peeled off on a peeling machine of wood blocks, after which the wood block to facilitate the peeling process was previously heat treated with steam or hot water.
  • the artificial wood elements are then cut from Holzpreßlingen, which consist of the interposition of adhesive stacked together and pressed together veneer sheets.
  • the veneer sheets are pressed into U- and / or V-shaped blocks, in which the fibrillation of the individual veneer lamellae run parallel to each other.
  • artificial wood elements are cut on a rotary cutting machine, which, however, have no uniform design and size.
  • a similar process is known, for example, from US Pat. No. 3,418,195 A, in which a compact of veneer sheets glued together is shaped in a U-shaped or V-shaped manner between a male mold and a die of a press, in both the longitudinal and transverse directions After curing of the glue in the block longitudinal direction veneer sheets are peeled off. If rare precious woods are to be simulated, it is possible to simulate special pore areas and annual rings when veneering the veneer sheets between these thin aggregate veneer layers, which consist of veneer sheets pressed together and glued together in parallel, optionally other colors, whose fiber direction is in the stacking direction, ie transverse to the fiber direction the adjacent veneer sheets, is aligned (DE 3 148 577 A).
  • a major disadvantage of the known method is that, especially in the area of the gates, a significant loss of material occurs and that the veneer sheets pressed wood blocks with increasing block thickness do not have a consistently uniform drawing, so that in particular when using thicker wood blocks from which flat wood elements are to be cut off , no similar drawing of all of the same compact cut wood elements can be guaranteed.
  • the invention is therefore an object of the invention to provide a method of the type described above, with the most simple way artificial wood elements can be made as natural as possible, similar and predeterminable fladerartiger drawing.
  • the invention solves this problem in that the sectionpreßlinge be arched between the male and female both longitudinally and transversely of the rotary veneer layers, wherein the peelable veneer layers are deformed with respect to a median plane on both sides undulating Operapreßlingen with a three-dimensional wavy surface structure, and that the Wooden elements in order to achieve a flat-like drawing parallel to the central planes are separated in layers from the compact.
  • the compact is not manufactured in one step, but it is first Partpreßlinge of several peeled veneer layers pressed with respect to a median plane to both sides, ie perpendicular to the median plane, running, three-dimensional wave structure, whereby the Crystalpreßlingen of the die and patrix a surface with three-dimensional valleys and hill structure is imprinted. Subsequently, several similar Partpreßlinge superimposed form-fitting and pressed with the interposition of binder in the press to the compact, wherein the Detailpreßlingen and the compact of the mold is always impressed the same three-dimensional wavy surface structure.
  • Rotary cut veneers which are peeled off endlessly from a tree trunk, are glued, for example, in such a way that, after being pressed, they have a drawing oriented in the longitudinal direction of the board.
  • peeling microcracks are od by the compression molding with interim release of the binder, such as glue.
  • the binder such as glue.
  • hardness and compressive strength as well as the wear resistance of the wood elements according to the invention increase over solid wood elements. Due to the more irregular pores compared to solid wood sawing veneers, wood elements produced by a process according to the invention also have a greater thermal resistance to solid wood.
  • the method according to the invention thus provides the possibility of reproducibly producing wood motifs in a simple manner, the wood elements also having improved mechanical properties compared to natural wood.
  • a particularly uniform continuous drawing for all wood elements can be achieved when the peeled veneer layers are pressed with a thickness of 1 to 4mm to Operapreßlingen with a thickness of 10 to 60mm, in particular from 30-40mm, and from the three to, for example ten compacts joined compact wooden elements are sawn in a thickness of 2 to 10mm.
  • the top layer of wood should meet the highest thermal and mechanical requirements, it is recommended if the top layer manufactured by a process according to the invention and on the base body applied wood element
  • a plurality of thin rotary veneer layers 1 is stacked with the interposition of a binder and compressed between male and female mold 3 3 of a press, not shown to Operapreßlingen 4 desired shape.
  • the peeled veneer layers are first pressed with intermediate of the binder between the male part 2 and die 3 to Generalpreßlingen 4 approximately constant thickness with both longitudinally and transversely wavy peeling veneer layers 1 (Fig. 3 and 4).
  • the rotary veneer layers 1 and the partial pressed bodies 4 of the male part 2 and die 3 are impressed with a three-dimensional wave-shaped surface structure in the form of valleys and hills, as can be seen in particular from FIGS. 3 and 4.
  • a top layer for a parquet with the thickness of 2 to 10 mm is to be created with the method according to the invention, it is recommended that peeling wood veneers 1 having a thickness of 1 to 3 mm and a length of 1300 to 2500 mm and a width of 150 to 250 mm to be pressed into cuboid Operapreßlingen 4 with a thickness of about 30 mm between the die 3 and male part 2.
  • a broader layer position for example, six pre-pressed Operapreßlinge 4 of the same shape are pressed together, whereby a compact 5 is formed with a thickness of about 180-200mm. Since the peeled veneer layers are slightly displaced relative to each other during pressing, it may be necessary to plan the obtained compact prior to sawing on its side surfaces in order to obtain a flat compact.
