Abstract

Beschrieben ist eine Presse zum Herstellen von Tellern od. dgl. mit einem zum Pressen gegen eine Gegenform Heran­ fahrbaren Preßstempel, der der Innenform des zu pressenden Tellers od. dgl. entsprechend geformt ist, und mit einer einen Hohlraum in der Gegenform abschließenden, an ihrem den Abmessungen des Randes des fertigen Tellers angepaßten Rand eingespannten, elastischen Membran, die mit einer den Fuß des Tellers entsprechenden Ringrille versehen ist und auf der pulverförmige Porzellanmasse bei auf Abstand von ihr gefahrenem Preßstempel in den durch die Einspannung gegebenen Grenzen verteilbar ist, wobei der von der Mem­ bran abgedeckte Hohlraum mit einem Druckmittel füllbar ist, das nach Heranfahren des Preßstempels auf die auf der Membran verteilte pulverförmige Porzellanmasse unter Druck setzbar ist. Der Preßstempel weist dabei eine Beschich­ tung auf, die am Rand mit einem in Richtung auf die Membran vorgewölbten Ringwulst versehen ist. Gegenüber diesem Ringwulst kann im Rand der Membran eine in sich geschlos­ sene Ringnut vorgesehen sein. A press for producing plates is described or the like. With one for pressing against a counter mold mobile press ram, the inner shape of the to be pressed Tellers od. Like. Is shaped accordingly, and with a Cavity in the final form, at its the Customized dimensions of the edge of the finished plate Edge clamped, elastic membrane with a Base of the plate corresponding ring groove is provided and on the powdered porcelain mass at a distance from it Press ram driven by the clamping given limits is distributable, whereby the Mem bran covered cavity can be filled with a pressure medium, that after moving the ram to the on the Membrane distributed powdered porcelain under Pressure can be set. The press ram has a coating tion on the edge with a towards the membrane bulging ring bead is provided. Towards this Ring bead can be closed in itself in the edge of the membrane Sene ring groove may be provided.
