Description

Gitterverstärktes Holzfurnier Lattice-reinforced wood veneer

Holzfurniere werden in großen Umfang verwendet'. Wood veneers are used extensively '.

Vielfach werden bei der Herstellung von Möbeln und dergleichen keine Vollholzprofile oder Leisten verwendet, sondern vorgeformte Kernprofile aus preiswerteren Hartholz, Spanplatten, oder Hartfaserplatten. Diese werden mit einem dünnen Holzfurnier ummantelt und geben so den Anschein eines Vollholzteiles.In many cases, in the manufacture of furniture and the like, there are no Solid wood profiles or strips are used, but preformed core profiles made from cheaper ones Hardwood, chipboard, or hardboard. These are covered with a thin wood veneer encased and give the appearance of a solid wood part.

Da Holzf'urniere aber leicht brechen, ist es angezeigt, sie vor dem Ummanteln zu stabilisieren, um beim Verformen und anschlieRenden Verleimen mit Hotmelt ein Brechen zu verhindern. Dazu sind verschiedene Verfahren vorgeschlagen worden. However, since wood veneers break easily, it is advisable to remove them before To stabilize the sheathing in order to be able to shape it and then glue it with hotmelt to prevent breakage. Various methods have been proposed for this purpose.

Eine Methode besteht darin, ein Holzfurnier mit einem Klebeband abzudecken, und dies nach dem Verleimen von der Oberfläche wieder zu entfernen. One method is to cover a wood veneer with an adhesive tape, and to remove this from the surface again after gluing.

Die Nachteile dieser Methode liegen auf der Hand, Klebstoffrückstände können an der Furnieroberfläche verbleiben, und in der Praxis hat sich dies nicht durchsetzen können.The disadvantages of this method are obvious, glue residue can remain on the veneer surface, and in practice this has not been the case can enforce.

Zur Zeit werden Furniere an der Unterseite mit einem Vlies beklebt, ausgerüstet mit einer Spezialimprägnierung z.B. PVAC-dispersion, das auch bei Temperaturen über 1000C noch zuverlässig haftet. Currently, veneers are glued to the underside with a fleece, Equipped with a special impregnation, e.g. PVAC dispersion, which also works at temperatures still reliably adheres above 1000C.

Das Vlies ist dabei z,B, mit PVAC imprägniert und wird vor dem Verkleben mit dem Holzfurnier aktiviert.The fleece is, for example, impregnated with PVAC and is before gluing activated with the wood veneer.

Beim Ummanteln wird dann das Vlies mit Hotmelt auf den vorgeformten Kern verklebt, wobei sich jedoch nachteilig auswirkt, daß eine zuverlässige Verklebung zwischen Hotmelt und dem Dispersionsimprägnierten Vlies problematisch ist und häufig zu Ablösungen und Reklamationen führt.When sheathing, the fleece is then hotmelt onto the preformed Core glued, but this has the disadvantage that reliable gluing between hotmelt and the dispersion-impregnated fleece is problematic and often occurs leads to replacements and complaints.

Aus der DE-PS 2 901 728 ist es bekannt, dekorative Teile, die später auf z.B. Stoffe aufgebracht werden sollen, vorher in den richtigen Abständen zueinander zu fixieren. Das Fixieren erfolgt dabei dadurch, daß die dekorativen Teile mit einer Schmelzkleberschicht versehen und auf einem weitmaschigen Träger fixiert werden. Es werden also Teile positiv nisiert, die später mit dem gleichen Schmelzkleber, mit dem sie fixiert wurden, auch verklebt werden. From DE-PS 2 901 728 it is known decorative parts that are later to be applied to fabrics, for example, beforehand at the correct distances from one another to fix. The fixation takes place in that the decorative parts with a A hotmelt adhesive layer is provided and fixed on a wide-meshed carrier. So parts are positively nized, which are later with the same hot melt adhesive, with which they were fixed, can also be glued.

Nachteilig an dieser Lösung ist es, daß bei der Verarbeitung die Stabilisierung der Teile verlorengeht, da der eingesetzte Hotmelt in der Wärme unter Verarbeitungsbedingungen die Verklebung zum fixierten Teil hin löst, was im Falle eines Furniers zum Verrutschen und Verlust der Armierung/Stabilisierung führt.The disadvantage of this solution is that the stabilization during processing of the parts is lost because the hotmelt used is exposed to heat under processing conditions the bond to the fixed part loosens, which in the case of a veneer causes it to slip and loss of reinforcement / stabilization.

Aufgabe der Erfindung war es hier Abhilfe zu schaffen, insbesondere ein glasfaserverstärk tes Holzfurnier mit Hotmelt-Kleber zu verkleben, das die Nachteile des Standes der Technik nicht, oder zumindest in wesentlich geringerem Umfange aufweist. The object of the invention was to provide a remedy here, in particular To glue a glass fiber reinforced wood veneer with hotmelt glue, the disadvantages of the state of the art does not have, or at least has to a much lesser extent.

Demgemäß besteht die Erfindung in einem git teer~, insbesondere faserverstärkten Holzfurnier das dadurch gekennzeichnet ist, daß es als Gitter verstärkung ein grobmaschiges Gitter aufweist, das mit einem Leim imprägniert und auf das Holzfurnier aufgeklebt ist Vorteilhaf't ist der Leim ein Polyvinylacetat (PVAC) oder andere Dispersionsleime. Beim Verkleben des imprägnierten Gitters mit dem Holzfurnier wird vorteilhaft der Leim mit einem Lösungsmittel, wie Essigester, aktiviert. Accordingly, the invention consists in a tar, in particular fiber-reinforced Wood veneer which is characterized in that it is reinforcement as a grid has a coarse-meshed grid, which is impregnated with a glue and on the wood veneer glued on is advantageous if the glue is a polyvinyl acetate (PVAC) or other Dispersion glues. When gluing the impregnated grid with the wood veneer, the glue is advantageously activated with a solvent such as ethyl acetate.

Von besonderem Vorteil ist es, als Glasfasergitter ein offenmaschiges Gewebe zu verwenden. It is particularly advantageous to use an open-meshed glass fiber grating Fabric to use.

Beim Verkleben mit Hotmelt resultiert dadurch eine zuverlässige Verbindung des Furniers zum Verklebungs untergrund, da der Hotmelt durch das Gelege eine direkte Verbindung zum verstärkten Material herstellt, ohne bei dem Verklebungsvorgang die Haftung der Verstärkung zum verstärkten Material hin zu lösen.When gluing with hotmelt, this results in a reliable connection of the veneer to the bonding surface, as the hotmelt has a direct Establishes a connection to the reinforced material without the To solve the adhesion of the reinforcement to the reinforced material.

Vorteilhaft besteht ferner das Gitter aus einem Glasfasergitter aus flachen Glasfasersträngen. The grating also advantageously consists of a glass fiber grating flat fiberglass strands.

Damit wird erreicht, daß die Armierung nicht zu sehr auf dem Holzfurnier aufträgt.This ensures that the reinforcement does not touch the wood veneer too much applies.

In der Fig. 1 ist eine beispielhafte Ausführungsform der Erfindung dargestellt, ohne damit den Schutz auf diese Ausführungsform beschränken zu wollen. Diese Fig. 1 zeigt einen Ausschnitt eines Holzfurniers 1, auf dem sich ein grobmaschiges Glasfasergitter 2 befindet. Dieses Glasfasergitter 2 weist eine PVAC-Imprägnierung auf. Dieses Holzfurnier kann als flächiges Gebilde oder aber locker aufgerollt vorliegen, je nach Biegsamkeit und sohn~ stigen Eigenschaften des verwendeten Holzfurniers, wie dies an sich bekannt ist. In Fig. 1 is an exemplary embodiment of the invention without wishing to restrict the protection to this embodiment. This Fig. 1 shows a section of a wood veneer 1 on which a coarse-meshed Fiberglass grating 2 is located. This glass fiber grating 2 has a PVAC impregnation on. This wood veneer can be available as a flat structure or loosely rolled up, depending on the flexibility and other properties of the wood veneer used, as is known per se.

Verarbeiten läßt sich das erfindungsgemäße Furnier in der üblichen Weise, insbesondere indem man Hotmelt zur Verklebung verwendet. Dabei kann man z.B. das Hotmelt aus der Schmelze aufbringen oder man kann das erfindungsgemäße Furnier zuvor mit Hotmelt beschichten und dieses vor dem Verkleben durch Hitze reaktivieren. The veneer according to the invention can be processed in the usual way Way, especially by using hot melt for gluing. You can e.g. apply the hotmelt from the melt or the veneer according to the invention can be used coat with hotmelt beforehand and reactivate it with heat before gluing.
