  • a veneer peeling machine or circular peeling machine is also clamped in a veneer peeling machine or circular peeling machine and rotating against it fixed knife is guided.
  • Less common today are the up to 3 mm thick sawn veneers, which are made on veneer frames or Hamburg saws.
  • Fibreboard material is a real wood veneer comparatively thick, stiff, and brittle and unsuitable for tight rolling. That is why a furniture component is covered with a real wood veneer mechanically only on a flat level in a pressing process. Profiling in particular had to be documented separately, which is often only possible by hand.
  • profiled furniture components of this type for example furniture fronts
  • the invention sets itself the task of a method for sheathing a
  • the component may also have a comparatively large width.
  • the provision of the sliced veneers on an elastic support as an endless belt allows the use of very thin real wood veneers, so that the roll veneer can be wound up in a film in a comparable manner and made available for the sheathing of a furniture component.
  • the roll veneer is very carefully provided with an adhesive, especially a hot glue, in one

  • a large number of pinch rollers with different axes also ensures exact positioning and sufficient pressure.
  • furniture components for example furniture fronts
  • Peeled veneers made of comparatively inexpensive wood, for example poplar wood can be produced inexpensively.
  • a particularly high degree of homogeneity with regard to the color tone and the structure of the veneer is further achieved by the in particular multiple gluing to blocks and the subsequent removal of sliced veneers. This means that entire series of fronts, for example, can be covered with a real wood veneer that have a uniform color and, in particular, damaged furniture components can also be easily replaced even after a long period of time, since the color and structure remain largely the same regardless of the material.
  • the length of the sliced veneer to be laminated corresponds to the width of the roll veneer. Because of this measure, you can large widths can be achieved, for example of over 60 cm, which is usually sufficient in the furniture industry. Sliced veneers created on conventional sliced veneer machines can thus be used in the method according to the invention.
  • a nonwoven, in particular one of 23 to 25 g, is preferably used as the elastic carrier, which is laminated on in two work steps.
  • This fleece is expediently colored in accordance with the veneer color so that it is not noticeable.
  • the fleece lamination allows the upper side to be sanded, for which purpose the roller veneer is expediently used. After sanding, the thickness of the roll veneer is still preferably about 320 micrometers, so it is comparatively thin.
  • a top coating with an elastic lacquer, in particular a UV-resistant, two-layer lacquer smoothes and seals the veneer surface on the visible side.
  • the furniture component has a base support made of a fiberboard material, that a groove is made in the base support, and that an especially profiled MDF strip is glued into the groove.
  • Medium density fiberboard material is much more suitable for profiling than the commonly used fiberboard material.

Abstract

Procédé de passage en machine pour le placage mécanique, en particulier de meubles larges et profilés, avec des feuilles de placage (7, 14) en bois véritable, selon lequel des feuilles de placage tranchées sont réunies en bande continue par collage sur un support élastique, puis déroulées et coupées à la longueur en tant que placage en rouleau (7, 14). Ensuite, le placage en rouleau (7,14) est enduit de colle sur une face, puis déposé via des cylindres déviateurs sur toute la largeur et sur deux arêtes longitudinales (12) du meuble profilé (4). Le placage (7, 14) est alors mis en position et pressé par une pluralité de cylindres de pression (11, 18, 20), segment par segment, profilages compris. On obtient ainsi un meuble profilé à extension plane dont au moins une face plate (5, 9) et deux faces longitudinales opposées (12), y compris les profilages préalablement prévus, sont intégralement pourvues d'un placage en bois véritable d'un seul tenant.
