- Veneer parts which are formed wholly or at least partially of veneer wood, are known in a variety of configurations and suitable for various types of use.
- veneer parts offer themselves primarily as a visible decorative layer, e.g. for floor coverings, such as par chain, for wall and ceiling coverings, furniture, musical instruments, housing of any kind or especially forppeinnenveremployedsmaschine and equipment, such as dashboards, center consoles, door trim parts, armrests, steering wheels and the like.
- the veneer part While in substantially planar articles, the veneer part is prefabricated in a relatively simple manner, cut to size and bonded to a corresponding support, e.g. is glued, it is known for the production of moldings with contrast, more complex surface geometry, insert a prefabricated wood veneer in a mold, after which it is back-injected or hot-pressed with either a thermoplastic and / or thermoelastic polymer, or it is back-injected with hardenable resins and become the resins cured to a thermoplastic or thermosetting polymer
- the molded part thus produced then has on the visible side the decorative veneer part which is firmly bonded to the polymer support. It is advantageous in addition to ensuring a relatively simple and inexpensive mass production in particular the possibility that with the
- wood veneers may also be applied to non-polymeric supports, such as wood fiber, plasterboard, and the like, which may be by gluing or any other known type of bonding or coating.
- DE 10 2004 062 646 B4 describes an interior trim part for motor vehicles and a method for its production, wherein the interior trim part has a visible surface of a wood veneer, which is provided on its inside with a fleece over which it is applied to a plastic carrier layer is.
- the wood veneer is first provided with the fleece on its non-visible side, for example by gluing, after which it is back-injected with the carrier polymer in an injection mold.
- WO 00/27926 A1 describes a molded part which has a carrier made of thermoplastic or thermoelastic polymers and a decorative layer connected to the carrier, which may be configured inter alia in the form of wood veneers.
- the decorative layer is pressed at elevated pressure and temperature, for example by means of a hot press, into the at least surface-plasticized polymer of the support, wherein between the polymer support and the debris.
- a fiber layer can be arranged in order to prevent penetration of the plasticized polymer to the visible side of the open-pored decorative layer, but nevertheless to ensure a permanent fusion bond between the polymeric carrier and the decorative layer.
- DE 295 20 343 U1 describes a braiding tape for the production of braids by gluing a strip-shaped plywood with a textile fabric which is arranged between two veneer lumbers, so that the textile fabric is completely covered on both sides with one plywood each.
- DE 201 20 258 Ul a similar braiding material strips of veneer wood for the production of surface or Formflechtwerken is known, the veneer strips in turn can be configured multi-layered and glued together through intermediate tissue layers under pressure. The veneer strips should be compressed at least in the longitudinal direction in order to improve the bending properties and the tensile strength of the veneer strips.
- the invention is therefore based on the object to propose a method for producing a novel veneer part of the type mentioned, which has a aesthetically perceived structure, but nevertheless a high flexural strength, in order to develop the application for objects or moldings with relatively complex surface geometries , It is further directed to such a veneer part as well as to a molded part provided with such a veneer part.
- this object is achieved with a method for producing a veneer part with a braid or fabric of at least two substantially strip-shaped bands, wherein at least one of the strip-shaped bands formed from veneer wood and has been produced by cutting a corresponding plywood blank, the method following steps include:
- the invention further provides a veneer part, in particular produced by means of such a method, comprising a braid or fabric of at least two substantially strip-shaped strips which are pressed together to form a substantially flat surface, wherein at least one of the strip-shaped strips of veneer wood is formed.
- the invention provides for solving this problem, a molding with a veneer part of the aforementioned type, wherein the veneer part is connected to a dimensionally stable carrier, in particular of at least one polymer.
- the veneer part according to the invention or the molded part provided with such a veneer part is able to give the viewer a novel aesthetic impression due to the two or more interwoven or woven substantially strip-shaped bands of the veneer part, not only by the type and optionally by the grain the type of wood used, but in particular by the arrangement of the strip-shaped bands in the fabric or braid is largely determined. Due to the compression of the fabric or braid produced, which, as explained in more detail below, in particular as hot pressing at elevated temperature can be performed, the veneer part nevertheless has a largely flat surface, so that it is an optically aesthetic visible surface and a conventional veneer part has corresponding feel and no major grooves or grooves, in which dirt can accumulate.
- the wood fibers of the at least ei ⁇ NEN or in particular a plurality formed from plywood strip-like belts (after cutting a corresponding plywood blank) or their plywood blank are broken up (prior to cutting the strip-shaped bands)
- approaches the veneer section can furthermore especially a give surprisingly high flexural strength, so that it can be applied to moldings with very complex surface geometries, such as their edges, projections, grooves, undercuts or the like across, without the veneer part takes damage or even breaks.
- the invention is based on the basic idea that primarily the wood fibers of the strip-shaped strips or the veneer wood blank from which the strip-shaped strips are cut, and in particular the predominantly arranged in the extension direction of the bands wood fibers limiting the bending strength of the braid or fabric impact.
- the breaking up of the wood fibers in particular at least those with a direction of extension of the substantially strip-shaped strip extending Clearreckungidesskomponente, thus leading to a high flexibility and consequently to a very high bending strength of the strip-shaped bands, so that the finished braided or woven, pressed veneer part non-destructive is moldable to geometries with very small bending radii and also remains permanently in the desired ' shape.
- the inventive arrangement of the strip-shaped bands in a mesh or fabric increases the tensile and flexural strength of the veneer part, so that it is mechanically resistant to conventional veneers and thus, as further below explained, can be formed with a very small thickness.
- a molded part provided with such a veneer part can be used wherever conventional veneer parts have hitherto been used, for example for floor coverings such as parquet, for wall and ceiling coverings, furniture, musical instruments, housings of any kind or in particular also for vehicle interior trim parts and equipment, such as dashboards, center consoles, door trim parts, armrests, steering wheels and the like.
- the expediently dimensionally stable carrier of the molded part may in particular be one based on polymers, which may optionally be fiber-reinforced to improve their mechanical material properties, the veneer prefabricated and then arranged in a known manner in a mold and with a thermoplastic and / or thermoelastic polymer can be back-injected or hot-pressed.
- the carrier need not necessarily be a polymer-based, but the veneer part according to the invention, of course, by means of any known connection methods, such as bonding, coating, (hot) press and the like, on other types of support , as on the basis of wood fiber materials, eg in the form of so-called MDF materials, gypsum plasterboard materials and the like.
- the very high bending strength of the veneer part in turn opens up the possibility to apply it to complex or with more or less sharp edges, grooves, projections, undercuts provided carriers, purely by way of example furnishings, such as furniture, are mentioned.

It comprises on the one hand a passively or in particular by means of a motor drive (not shown) actively rotatable first roller 10 of a rigid material, for example of metal, and a coaxial and opposite thereto rotatable second roller 11, which at least umfssegextig of a resilient material, such as Rubber, silicone or the like, is made.
- the second roller 11 has a rotatably mounted core 12 made of a rigid material, such as metal, as well as a vollumfnature coating 13 of the elastically yielding material.
- the motor drive of the rigid first roller 10 may comprise, for example, a drive roller 14 which is frictionally engaged with it on the surface.
- the circumferentially elastically resiliently configured second roller 11 may be passively or likewise motor-driven and rotationally synchronized in terms of its circumferential speed with that of the first roller 10 (not shown).
- the gap between the first roller 10 and the second roller 11 is preferably selected to be smaller than the thickness of the plywood blank, and depending on the superficial elasticity of the roller 11, it may in particular be almost equal to zero.
- the diameter of the rigid first roller is expediently appreciably smaller than the diameter of the yielding elastic roller.
- the veneer blank when moved through the gap between the rolls 10, 11 at a suitable feed rate v, it will move around a peripheral portion of the small diameter rigid second roll 10 with surface penetration into the large diameter elastically compliant second roll 11 a direction of movement component extending in the radial direction of the rollers 10, 11 is deflected, so that in particular those wood fibers are broken up with an extension direction component running in the direction of movement v of the plywood blank, which is able to impart a very high flexural strength.
- the veneer wood blank can optionally be ground on its side opposite the adhesion promoter layer 4, whereafter it is cut to form the strip-shaped tapes 1a, 1b. Care should be taken here that the cutting lines run essentially parallel to the direction of movement v, with which the veneer wood blank has been moved by the roller arrangement (see Fig. 4), in particular in the direction of extension of the strip-shaped bands 1 a, 1 b to ensure high flexibility of the same at a very high flexural strength.
- the braid or fabric of the strip-shaped bands la, lb can then be hot pressed to obtain the largely flat surface 2, wherein the adhesive layer 4 for a permanent fixation of the strip-shaped bands la, lb together.
- the veneer part thus obtained can be provided on its side opposite the visible surface 2 with the adhesion promoter layer 3, which in turn is immobilized, for example, on a textile or paper layer, which expediently proceed together with the hot-pressing of the braid or fabric produced from the strip-shaped tapes 1a, 1b can by in the impregnated with the adhesive layer 3 impregnated textile or Pap.ier für on the side opposite the visible side of the braid or fabric side is inserted into the hot press.
