Abstract

Decorative layers, particularly fabric layers are applied to a magnetically non-conducting carrier by the use of a high frequency activated adhesive, and the laminate is applied to the main component to be decorated. Use of the intermediate carrier layer is eliminated if the carrier is a metal plate which acts as the earth electrode during the high frequency process. A second electrode acts as the punch for pressing the decorative layer onto the carrier. USE/ADVANTAGE - The process is used in automobile construction for applying decorative finishes e.g. to doors and eliminates the use of an intermediate non-conductive carrier.

Description

Aus der DE-A 35 22 878 ist ein Verfahren zum Herstellen von dekorativen Verkleidungselementen, insbesondere für Türen von Kraftfahrzeugen, bekannt. Hierbei wird eine Stoffschicht, die u. U. noch mit einer Schaumstoff­ schicht auf ihrer Rückseite versehen ist, mit Hilfe eines HF-aktivierbaren Klebers auf ein Tragelement aus Holzfaserwerkstoff, ABS o. dgl. mit Hilfe eines Hoch­ frequenzfeldes aufgebracht. Hierzu werden zwei Form­ elektroden verwendet, zwischen denen das Tragelement mit dem Kleber und dem Stoff eingelegt wird. Die beiden Formelektroden werden mit Spannung versorgt und dienen gleichzeitig dazu, den Stoff bis zum Aushärten des Klebers auf das Tragelement zu pressen.DE-A 35 22 878 describes a method for manufacturing of decorative cladding elements, in particular for Doors of motor vehicles, known. Here is a Layer of fabric that u. U. still with a foam layer is provided on the back with the help an HF-activatable adhesive on a support element Wood fiber material, ABS or the like. With the help of a high frequency field applied. This will take two forms electrodes used, between which the support element with the glue and the fabric is inserted. The two Formula electrodes are supplied with voltage and serve at the same time, until the fabric has hardened Press adhesive onto the support element.

Der Vorteil dieses Verfahrens liegt darin, daß lösungs­ mittelfreie Kleber verwendet werden können und kein Kleber durch den Stoff durchschlägt, so daß auf der Stoffoberfläche Verfärbungen entstehen können. Im letzteren Fall ist dann das hergestellte Verkleidungs­ element unbrauchbar.The advantage of this method is that solution medium-free glue can be used and no Adhesive penetrates through the fabric, so that on the Discolouration of the fabric surface can occur. in the the latter case is the cladding produced element unusable.

Der Nachteil dieses Verfahrens liegt darin, daß ein zusätzliches Tragelement vorgesehen werden muß, auf das der Stoff aufgebracht wird. Stoff und Tragelement werden dann zur Verkleidung verwendet und somit nochmals mit Hilfe von Befestigungsmitteln an den zu verkleidenden Bauteilen angebracht.The disadvantage of this method is that a additional support element must be provided on the the fabric is applied. Fabric and support element then used for cladding and thus again with  With the help of fasteners on those to be clad Components attached.

Aufgabe der vorliegenden Erfindung ist es, hier Abhilfe zu schaffen und das bekannte Verfahren so weiterzubil­ den, daß die zu verkleidenden Teile direkt beschichtet werden können.The object of the present invention is to remedy this to create and continue the known method that the parts to be covered are coated directly can be.

Diese Aufgabe wird erfindungsgemäß durch die kennzeich­ nenden Merkmale des ersten Anspruchs gelöst. Aufgrund der Erkenntnis, daß das zu kaschierende Tragelement direkt das zu verkleidende Blech sein kann und dies nicht zu einer Störung des Magnetfeldes führt, wenn das Tragelement als Masseelektrode fungiert, können die bisher verwendeten Tragelemente aus magnetisch nicht­ leitenden Materialien ersatzlos weggelassen werden. Dadurch ist es beispielsweise möglich, den dem Fahr­ zeuginnenraum zugewandten Teil eines Schiebedaches direkt zu verkleiden und nicht mehr das Metallteil mit Befestigungsöffnungen zu versehen, in die dann das aus Holzfaserwerkstoff oder anderem bestehende kaschierte Verkleidungselement befestigt wird.This object is inventively characterized by nenden features of the first claim solved. Because of the knowledge that the support element to be concealed can be directly the sheet to be clad and this does not interfere with the magnetic field if that Supporting element acts as a ground electrode, the Magnetic support elements not previously used conductive materials are omitted without replacement. This makes it possible, for example, for the driver part of a sunroof facing the interior to dress directly and no longer with the metal part To provide mounting holes in which then that Wood fiber material or other existing laminated Cladding element is attached.

Als Dekorschicht kommt hauptsächlich Stoff in Betracht, der entweder unmittelbar oder mittelbar unter Zwischen­ schaltung einer geeigneten Schicht, beispielsweise einer Schaumstoffschicht o. ä., auf das zu verkleidende Blech­ teil aufgeklebt wird.The main decorative layer is fabric, which is either directly or indirectly under intermediate switching a suitable layer, for example one Foam layer or similar on the sheet to be clad part is glued on.

Die Weiterbildung nach Anspruch 2 vereinfacht die zur Kaschierung notwendigen Werkzeuge, da nunmehr nur noch eine Elektrode vorgesehen werden muß, die gleichzeitig als Stempel fungiert, um den Stoff während des Aushär­ tens des Klebers anzupressen. Hierbei kann mit einem sehr geringen Druck gearbeitet werden, so daß auf jeden Fall sichergestellt ist, daß der Kleber nicht durch­ schlägt und zu einer Verfärbung des Stoffes führt.The training according to claim 2 simplifies the Laminating necessary tools, since now only an electrode must be provided, which at the same time acts as a stamp on the fabric during curing of the adhesive. This can be done with a very low pressure can be worked, so that on everyone  Case it is ensured that the adhesive does not pass through strikes and leads to discoloration of the fabric.

Zur Anwendung des erfindungsgemäßen Verfahrens ist es gleichgültig, ob der Kleber auf das Dekormaterial, sprich Stoff, aufgetragen wird oder direkt auf das Tragelement. Als Kleber selbst wird in an sich bekannter Weise ein Hotmelt-PUR-Kleber verwandt. Dieser Kleber kann aufgesprüht werden oder in Folienform als Zwischen­ schicht eingelegt werden.It is to use the method according to the invention regardless of whether the adhesive is on the decorative material, i.e. fabric, is applied or directly on the Support element. As an adhesive itself is known in itself Way a hot melt PUR adhesive is used. That glue can be sprayed on or in foil form as an intermediate layer can be inserted.

Ganz allgemein kann mit dem erfindungsgemäßen Verfahren eine einwandfreie flächige Verbindung selbst in Kanten­ bereichen erzielt werden, so daß derart kaschierte Bleche jahrelang verwendet werden können, ohne optische Einbuße.In general, with the method according to the invention a perfect flat connection even in edges areas can be achieved so that such laminated Sheets can be used for years without being optical Loss.
