sowie nach diesem Verfahren hergestelltes Serviertablett Verfahren zur Herstellung eines rutschsicheren Serviertabletts sowie nach diesem Verfahren hergestelltes Serviertablett Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines rutschsicheren Serviertabletts, bei dem mit wärmehärtbaren Harzen überzogene oder imprägnierte Papierbögen übereinandergeschichtet werden, bei dem auf diesen Schichtkörper ein Gewebe aufgelegt wird, das zumindest auf seiner oberen Fläche mit einer Schicht aus einem pordsen thermoplastischen Material bedeckt ist und bei dem die auf diese Weise gebildete Anordnung in einer Form unter Anwendung von Wärme derart gepreßt wird, daß einerseits die erhabenen Teile der Schicht durch Polymerisation in synthetisches Gummimaterial umgewandelt werden und daß andererseits dem geschichteten Material die endgültige Form erteilt wird sowie auf ein nach diesem Verfahren hergestelltes Serviertablett.as well as serving tray made by this process procedure for the production of a non-slip serving tray and according to this process Manufactured serving tray The invention relates to a method of manufacture a non-slip serving tray which is coated with thermosetting resins or impregnated paper sheets are stacked on top of each other, in which on these Laminated body a fabric is placed on at least its upper surface is covered with a layer of a pordsen thermoplastic material and at the arrangement formed in this way in a mold with the application of heat is pressed in such a way that on the one hand the raised parts of the layer by polymerization be converted into synthetic rubber material and that on the other hand the layered one Material is given the final shape as well as on a manufactured according to this process Serving tray.
Bei einem bekannten Verfahren dieser Art werden mit wärmehärtbaren Harzen, wie z.B. Melaminharz oder Phenolharz beschichtete oder imprägnierte Papierbögen übereinander geschichtet. Uber diesen Stapel wird ein weiches Gewebe gelegt, das zumindest auf der oberen Fläche mit einer Schicht aus thermoplastischem Material, wie z.B. PVC beschichtet ist. Darauffolgend wird in einer Form die auf diese Weise gewonnene Einheit derart gepreßt, daß einerseits die erhabenen Teile der Schicht durch Polymerisation in synthetisches Gummimaterial umgewandelt werden und daß andererseits dem beschichteten Material die endgültige Form erteilt wird. Die mit diesem Verfahren hergestellten Serviertabletts sind steif, leicht, weisen eine gute mechanische und chemische Widerstandsfähigkeit auf und zusätzlich haben sie ausgezeichnete Antirutsch-Eigenschaften.In a known method of this type are with thermosetting Resins, such as melamine resin or phenolic resin coated or impregnated paper sheets layered on top of each other. A soft tissue is placed over this pile, the at least on the upper surface with a layer of thermoplastic material, e.g. PVC is coated. This is followed by the form obtained in this way Unit pressed in such a way that on the one hand the raised parts of the layer by polymerization be converted into synthetic rubber material and that on the other hand the coated one Material is given the final form. Those made with this process Serving trays are stiff, light and have good mechanical and chemical resistance and in addition they have excellent anti-slip properties.
Dieses bekannte Verfahren weist jedoch einen wesentlichen Nachteil auf: Während der Formung in der Form werden im Bereich der mit dem Harz beschichteten oder imprägnierten Papierbögen Gase und Dämpfe frei, die nicht vollständig entweichen können und die an der Oberfläche unter der PVC-Schicht oder dem diese tragenden Gewebe eingefangene Blasen bilden.However, this known method has a major disadvantage on: During the molding in the mold, in the area of the coated with the resin or impregnated paper sheets release gases and vapors that do not escape completely and those on the surface under the PVC layer or the one carrying it Tissues form trapped bubbles.
Wenn das Serviertablett der Form entnommen wird, rufen diese Blasen Oberflächenungleichförmig Seiten auf, die das Aussehen des Serviertabletts beeinträchtigen.When the serving tray is removed from the mold, these will call bubbles Uneven surfaces on sides that spoil the appearance of the serving tray.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art sowie ein nach diesem Verfahren hergestelltes Serviertablett zu schaffen, das diese Nachteile beseitigt.The invention is based on the object of a method of the above to create a serving tray made according to this process, that eliminates these disadvantages.
Diese Aufgabe wird ausgehend von einem Verfahren der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß das Gewebe und die Schicht Perforationen aufweisen.This task is based on a method of the aforementioned Type solved according to the invention in that the fabric and the layer perforations exhibit.
Durch diese Ausgestaltung des Verfahrens wird das Entweichen von Gasen und Dämpfen während des Formungsvorganges durch die Perforationen hindurch begünstigt, so daß sich eine einwandfreie Oberfläche mit gutem Aussehen ergibt.This configuration of the method prevents gases from escaping and dampening during the molding process through the perforations, so that a flawless surface with a good appearance results.
Eine Untersuchung des erfindungsgemäßen Seriertabletts zeigt, daß die Perforationen, nachdem sie ihre Aufgabe bei dem Freiwerden der Gase und Dämpfe erfüllt haben, am Ende des Formungsvorganges unter der Einwirkung der Wärme und des Druckes verschwinden.An examination of the serial tray according to the invention shows that the perforations after they do their job in becoming vacant the Gases and vapors have met at the end of the molding process under the influence of heat and pressure disappear.
Gemäß einer bevorzugten Ausgestaltung der Erfindung sind fünf bis zehn Perforationen oder Öffnungen pro Quadratzentimeter in der Deckschicht sowie dem diese Deckschicht tragenden Gewebe vorgesehen und diese Perforationen können vorzugsweise einen Durchmesser von 0,1 bis 0,2 mm aufweisen.According to a preferred embodiment of the invention, there are five to ten perforations or openings per square inch in the top layer as well the fabric carrying this cover layer is provided and these perforations can preferably have a diameter of 0.1 to 0.2 mm.
Ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens ist wie folgt: a) Es wird ausgehend von der Unterseite zur Oberseite ein Stapel aus mit Melaminharzen imprägnierten Papierbögen und mit Phenolharz imprägnierten Papierbögen gebildet, wobei die letzteren stärker mit Harz imprägniert sind als die ersteren; b) auf diesen Stapel wird ein Gewebe, vorzugsweise ein lose gewebtes Gewebe aufgelegt, das auf der oberen Fläche mit einer porösen Deckschicht aus PVC beschichtet ist, das gegebenenfalls einen Dekoreffekt aufweist und beispelsweise das Aussehen von Holz aufweist, wobei dieses Gewebe und die Deckschicht aus PVC vorher mit acht bis zehn Öffnungen mit 2 einem Durchmesser von 0,1 bis 0,2 mm pro cm versehen werden; c) die so gebildete Einheit wird auf die Formmatrize gelegt und dann unter Anwendung von Wärme mit einem Preßstempel bei einer Temperatur von ungefähr 1400C und einem Druck 2 von ungefähr 60 kg/cm über eine Zeitdauer von ungefähr 10 Minuten gepreßt, d) das geformte Serviertablett wird aus der Form entnommen und man läßt es abkühlen. Die ein Rutschen verhindernde Oberfläche des auf diese Weise gebildeten Serviertabletts weist keine Blasen oder andere Ungleichförmigkeiten auf.An embodiment of the method according to the invention is as follows: a) Starting from the bottom to the top, a stack of melamine resins is made impregnated paper sheets and phenolic resin-impregnated paper sheets, the latter being more heavily impregnated with resin than the former; b) on this A fabric, preferably a loosely woven fabric, is placed on the stack the upper surface is coated with a porous cover layer made of PVC, which optionally has a decorative effect and, for example, has the appearance of wood, wherein this fabric and the cover layer made of PVC beforehand with eight to ten openings 2 are provided with a diameter of 0.1 to 0.2 mm per cm; c) the so formed Unit is placed on the forming die and then using heat with a Press ram at a temperature of about 1400C and a pressure 2 of about 60 kg / cm pressed for a period of about 10 minutes, d) the shaped serving tray is removed from the mold and allowed to cool. The one that prevents slipping Surface of the serving tray formed in this way has no bubbles or other irregularities.
Gemäß einer weiteren Ausführungsform des Verfahrens wird der Formvorgang in zwei Schritten in der folgenden Weise ausgeführt: a) Zunächst wird zumindest ein Teil des Stapels der mit Harz beschichteten oder imprägnierten Papierbögen unter Auflegen eines Schutzpapierbogens auf diesen Stapel gepreßt, wobei dieses Schutzpapier ein pergamentartiges Papier sein kann, das verhindert, daß das Harz am Preßstempel der Presse anhaftet.According to a further embodiment of the method, the molding process carried out in two steps in the following way: a) First, at least part of the stack of resin-coated or impregnated paper sheets Placing a sheet of protective paper on top of this stack, this protective paper a parchment-like paper that prevents the resin on the ram clinging to the press.
b) Der Preßstempel wird angehoben und der Schutzpapierbogen wird entfernt; c) dieser Schutzpapierbogen wird durch die restlichen mit Harz beschichteten oder imprägnierten Papierbögen ersetzt, die mit dem Gewebe mit der Deckschicht abgedeckt sind, so daß die komplette Einheit gebildet wird; schließlich wird die endgültige Formung in der Formpresse durchgeführt.b) The ram is raised and the sheet of protective paper is removed; c) this sheet of protective paper is coated with resin or by the remaining Replaced impregnated paper sheets, which are covered with the fabric with the top layer are so that the complete unit is formed; eventually becomes the final Forming carried out in the molding press.
