Description

Verfahren zum Überziehen von Gegenständen mit Kunstharzen Zur Herstellung von mit Kunstharzmasse überzogenen Gegenständen ist es bereits bekannt, zunächst einen Kern des Gegenstandes aus Papier, Pappe o. dgl. so zu gestalten, daß er die gewünschte Form aufweist. Dieser Kern wird dann in eine flüssige oder halbflüssige Kunstharzmasse getaucht und hierauf in an sich bekannter Weise in einer mehrteiligen Form gepreßt, wobei Ungenauigkeiten der Formen und der Dicke der überzügsgchicht ausgeglichen werden können.Process for coating objects with synthetic resins For manufacture of objects coated with synthetic resin compound, it is already known, initially To make a core of the object made of paper, cardboard o. The like. So that he the Has desired shape. This core then turns into a liquid or semi-liquid Synthetic resin compound dipped and then in a manner known per se in a multi-part Pressed shape, with inaccuracies in the shape and the thickness of the coating layer can be compensated.

Erfindungsgemäß wird zum Überziehen von Gegenständen der vorgeformte Kern zunächst mit einem Haftmittel, z. B. mit Leim, überzogen. Anschließend wird auf das noch feuchte Haftmittel durch Bestreuen, Bestreichen, Aufpudern o. dgl. Kunstharzmasse aufgebracht. Der so behandelte Gegenstand wird dann vorteilhaft getrocknet und hierauf in an sich bekannter Weise gepreßt, wobei dem Werkstück die endgültige Form gegeben wird.According to the invention, the preformed one is used for covering objects Core first with an adhesive, e.g. B. with glue coated. Then will on the still moist adhesive by sprinkling, brushing, powdering or the like. Synthetic resin compound applied. The object treated in this way is then advantageously dried and then pressed in a manner known per se, the workpiece being the final Shape is given.

Bei dem Preßvorgang verbindet sich die Überzugsmasse mit der Oberfläche des Kernes. Die auf diese Weise an den meisten Stellen des Kernes sehr dünn hergestellte überzugsschicht verleiht dem fertigen Gegenstande das Aussehen .eines homogenen, durchgehend aus Kunstharz hergestellten Werkstückes.During the pressing process, the coating compound bonds to the surface of the core. The one made in this way very thin in most parts of the core coating layer gives the finished object the appearance of a homogeneous, workpiece made entirely of synthetic resin.

Zur Erzielung verschiedenfarbiger Musterungen an bestimmten Stellen des zu überziehenden Gegenstandes kann. auf den Kern Kunstharzpülver verschiedener Zusammensetzung und Färbung unter Vermittlung des Haftmittels aufgetragen werden.To achieve different colored patterns at certain points of the object to be coated. on the core synthetic resin powder of various Composition and coloring are applied through the intermediary of the adhesive.

Auf der Zeichnung ist als Ausführungsbeispiel des Erfindungsgegenstandes eine flache Schale dargestellt: Mit i ist ein Kern aus Papier, Pappe o. dgl. bezeichnet, der die Endformen des herzustellenden Stückes noch nicht aufweist. Auf diesen Kern ist die Kunsthärzschicht 2 unter Benutzung eines Haftmittels aufgebracht. Bei dem Preßvorgange sind bei diesem Werkstücke die Kante 3 und der Rand q. gebildet worden; die die entsprechende Preßforin zeigen.In the drawing is an exemplary embodiment of the subject matter of the invention a shallow bowl is shown: i denotes a core made of paper, cardboard or the like, which does not yet have the final shape of the piece to be produced. On this core the resin layer 2 is applied using an adhesive. In which Pressing processes are edge 3 and edge q in this work piece. been formed; which show the corresponding press form.

Durch die Erfindung wird der Vorteil @erreicht, däß Muster beliebiger Art auch unter Verwendung von Schablonen auf den Kern aufgebracht werden können, wobei diese durch das Haftmittel an den vorbestimmten Stellen festgehalten werden. So kann z. B. die Außenseite der Schale aus einer billigeren Überzugsmasse und deren Innenseite aus wertvollerem Preßstoff, z. B. in leuchtender Farbe, hergestellt werden. Durch das Aufbringen der überzugsmasse unter Zwischenschaltung des Haftmittels wird außerdem jede Blasenbildung vermieden. Ferner können sogenannte melierte Muster in vorherbestimmter Ausführung hergestellt werden.The invention achieves the advantage that patterns can be arbitrary Art can also be applied to the core using stencils, these being held in place by the adhesive at the predetermined locations. So z. B. the outside of the shell from a cheaper coating mass and their Inside made of more valuable pressed material, e.g. B. in bright color. By applying the coating compound with the interposition of the adhesive also avoided any blistering. Furthermore, so-called mottled patterns are manufactured in a predetermined design.

Durch die verhältnismäßig sehr dünne Überzugsschicht wird die Preßzeit wesentlich verkürzt. Außerdem ist es durch die allseitige gleichmäßige Verteilung des Preßgutes auf dem nachgiebigen Kern möglich, im allgemeinen schwer formbare Werkstücke, wie tiefe Behälter, Kannen o. dgl., herzustellen.The pressing time is reduced by the relatively very thin coating layer significantly shortened. It is also due to the even distribution on all sides of the pressed material on the flexible core possible, in general difficult to shape Workpieces such as deep containers, cans, or the like. To produce.
