Die Erfindung betrifft ein Verfahren zur Beschichtung der Oberfläche von aus zerkleinerten Faserstoffen und einem wärmehärtbaren Bindemittel dreidimensional geformten Preßkörpern mit einer Dekorschicht, wie einem lüdelholzfurnier, bei dem die Dekorschicht aus wenigstena einem langgestreckt flachen Körper besteht.The invention relates to a method for coating the surface of shredded fibrous materials and a thermosetting binder, three-dimensionally shaped pressed bodies with a decorative layer, such as a lüdelholz veneer, in which the decorative layer consists of at least one elongated flat body.
Ein solches Verfahren ist bekannt ( DE - OS 25 57 344 ). Die wenigstens auf einer Oberfläche dekorativ beschichteten Preßkörper sind aus einem nicht steigfähigen Gemisch von mit einem wärmehärtenden Bindemittel vermischten Faserstoffen in der Weise gepreßt, daß aus dem Gemisch zunächst durch Kaltpressen ein Vorpreßling hergestellt wird, der Vorpreßling zusammen mit der oder den dekorativen Deokschichten in eine Heißpresse eingesetzt wird, wo das zum Preßkörper geformte Gemisch beim Heißpressen gleichzeitig ausgehärtet und mit der dekorativen Deckschicht überzogen wird.Such a process is known (DE-OS 25 57 344). The pressed bodies, which are decoratively coated on at least one surface, are pressed from a non-rising mixture of fibrous materials mixed with a thermosetting binder in such a way that a pre-pressed part is first produced from the mixture by cold pressing, the pre-pressed part together with the decorative deodorant layer or layers in a hot press is used, where the mixture formed into the pressed body is cured during hot pressing and coated with the decorative top layer at the same time.

Das nicht steigfähige Gemisch besteht meist aus lignozellulosehaltigen Faserstoffen, wie zerkleinerten und getrockneten Holzspänen, Bagassefasern u.a., die mit einem wärmehärtbaren Kunstharz, wie einem Melamin - Harnstoffformaldehyd- oder Phenolformaldehydharz vermischt sind. Anstelle der zerkleinerten und getrockneten Holz- öder Bagassefasern können aber auch Fasern anderer Werkstoffe, wie Glasfasern, Steinwolle oder Asbestfasern, allein oder mehrere derselben miteinander gemischt, verwendet werden, denen entsprechende, vorzugweise organische Bindemittel zugesetzt 3ind.The mixture, which cannot be climbed, usually consists of lignocellulose-containing substances Fibers, such as shredded and dried wood chips, bagasse fibers, etc. thermosetting synthetic resin, such as a melamine - urea formaldehyde - or phenol-formaldehyde resin are mixed. Instead of the crushed and dried wood wastes But bagasse fibers can also be fibers of other materials, such as glass fibers, rock wool or asbestos fibers, alone or several of these mixed with one another, are used, corresponding, preferably organic, binders added 3ind.
Bei derartigen beschichteten Preßkörpern besteht die Dekorschicht beispielsweise aus einem Gewebe, einem Furnier, einer bedruckten Papierfolie, einer Kunststoffolie oder einem anderen geeigneten Werkstoff. Es ist weiterhin bekannt, über dieser Dekorschicht erforderlichenfalls noch eine transparente Schutzschicht vorzusehen,? die zusammen mit der Dekorschicht, vorzugsweise während des Heißpreßvorganges, aufgebracht wird. Für eine aolöhe Schutzschicht wird im allgemeinen sogenanntes klares Overlay Papier verwendet, das aus nicht gefülltem Alpha - Zellulosepapier oder aus einem Glasfaservlies besteht und· mit einem geeigneten Kunstharz getränkt bew. durch Eintauchen in ein Kunstharz beiderseits mit diesem bedeokt ist» Durch diese Schutzschicht wird im allgemeinen die Dekorschicht, die nach dem Aufpressen dieser transparenten Schutzschicht durch diese hinduroh sichtbar ist, hinreichend, beispielsweise gegen Verschleiß, geschützt»In such coated pressed bodies, the decorative layer consists, for example, of a fabric, a veneer, a printed paper film, a plastic film or another suitable material. It is still known to provide a transparent protective layer over this decorative layer if necessary? the is applied together with the decorative layer, preferably during the hot pressing process. For a high protective layer In general, so-called clear overlay paper is used, which is made from unfilled alpha cellulose paper or consists of a glass fiber fleece and · impregnated with a suitable synthetic resin by dipping into a synthetic resin is coated on both sides with this »Through this protective layer is generally the decorative layer, which after pressing on this transparent protective layer through this hindu is visible, sufficiently protected, for example against wear and tear »
Das bekannte Verfahren zur Beschichtung von Preßkörpern mit einer Dekorschicht hat 3ich in sehr großem Umfang bewährt und wird bei der Herstellung von im wesentlichenThe known method for coating pressed bodies with a decorative layer has 3ich to a very large extent proven and is used in the manufacture of essentially

Es ist jedoch nicht ohne weiteres anwendbar, wenn dreidimensional gewölbte Körper, beispielsweise gewölbte Deckel für Behälter, mit einer Dekorschicht versehen werden sollen.flat pressed bodies applied. However, it is not without it further applicable when three-dimensionally curved body, for example curved lids for containers, with a Decorative layer are to be provided.
Die der Erfindung zugrunde liegende Aufgabe besteht deshalb darin, das bekannte Verfahren in der Weise zu verbessern, daß mit ihm auch dreidimensional gewölbte Preßkörper beschichtet werden können und - falls die Dekorschicht eine Maserung oder ein Muster besitzt - diese auoh auf den gewölbten Flächen einen gleichmäßigen Verlauf behalten.The object on which the invention is based is therefore to improve the known method in such a way that that three-dimensionally curved pressed bodies can also be coated with it and - if the decorative layer has a grain or a pattern - these also keep an even course on the curved surfaces.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß der in örtlich begrenzten Bereichen mit Schlitzen und/oder Ausschnitten versehene Dekorschicht - Körper auf den vorzugsweise kalt vorgepreßten Preßkörper aufgelegt und beim Heißpreßvorgang unlösbar mit diesem verbunden wird«This object is achieved according to the invention in that the in locally limited areas with slots and / or Decorative layer provided with cutouts - body placed on the preferably cold pre-pressed pressed body and at Hot pressing process is inextricably linked to this «
