Description

Vorrichtung zur Herstellung von Rohgummiplatten. Nach dem Hauptpatent ist eine Vorrichtung zur Herstellung von Rohgummiplatten mit in die Oberfläche eingebetteten Fäden geschützt, bei welcher Unterdruck oder Überdruck in der mit dem Gummimantel belegten Trommel dadurch hergestellt werden kann, daß die an ihren Stirnseiten luftdicht abgeschlossene Trommel einen durchlochten oder aus Drahtgewebe bestehenden Mantel und eine Hohlachse besitzt, mittels deren Luft ausgesaugt oder Luft, Dampf oder Gas eingepreßt werden kann.Device for the production of raw rubber sheets. According to the main patent is a device for the production of raw rubber sheets with embedded in the surface Threads protected at what negative pressure or positive pressure in the one with the rubber jacket occupied drum can be produced in that the airtight at their end faces closed drum a perforated or made of wire mesh jacket and has a hollow axle, by means of which air is sucked out or air, steam or Gas can be injected.

Dies kann neuerungsgemäß unter Wegfall der Hohlachse auch dadurch erreicht werden, daß an einem Ende der Trommel in oder an derselben oder auch außerhalb mit entsprechender Rohrverbindung ein Ventilator oder Propeller angeordnet wird, dessen Antrieb unabhängig von dem der Trommel bzw. so erfolgt, daß seine Umdrehungsgeschwindigkeit entsprechend größer als die der Trommel ist, bzw. saugend oder pressend wirkt. Während iie eine Stirnwand derselben luftdicht abgeschlossen ist, hat die andere entsprechende Öffnungen für den Ventilator, mit dem damit der eHarderliche Unterdruck oder überdruck in der Trommel und die Erwärmung im Sinne des Hauptpatents erzeugt werden kann, regelbar durch seine Geschwindigkeit.According to the innovation, this can also be achieved by doing away with the hollow axle can be achieved that at one end of the drum in or on the same or outside a fan or propeller is arranged with the appropriate pipe connection, its drive takes place independently of that of the drum or so that its speed of rotation is correspondingly larger than that of the drum, or has a sucking or pressing effect. While If one end wall of the same is hermetically sealed, the other has a corresponding one Openings for the fan, with which the hard negative or positive pressure in the drum and the heating in the sense of the main patent can be generated, adjustable by its speed.

Die Zeichnung zeigt eine Ausführungsform des Erfindungsgegenstandes, und zwar Abb. i die Trommel in Ansicht mit Schnitt nach Linie A-B von Abb. z und Abb. z in wagerechtem Schnitt.The drawing shows an embodiment of the subject matter of the invention, namely Fig. i the drum in view with section along line A-B of Fig. z and Fig. Z in horizontal section.

Die Trommel a ist auf der Welle s gelagert und wird durch dieselbe in Drehung versetzt. Auf ihr sind die Gummiplattend gemäß dem Hauptpatent aufgelegt. Die eine Stirnwand a1 der Trommel a ist dicht abgeschlossen, dagegen besitzt die andere Stirnwand a2 einen Ansatz t, der in ein Rohr u hineinragt und sich in demselben drehen kann. Im Rohr u (oder auch außerhalb mit entsprechendem Anschluß) ist ferner ein Ventilator v angeordnet, der z. B. durch eine zur Welle s konzentrische Welle w angetrieben. wird. Durch diesen Ventilator v kann Luft, Gas oder Dampf in das Innere der Trommel gepreßt oder aus derselben abgesaugt werden.The drum a is mounted on the shaft s and is set in rotation by the same. The rubber plates are placed on it according to the main patent. One end wall a1 of the drum a is tightly sealed, while the other end wall a2 has an extension t which protrudes into a tube u and can rotate in the same. In the tube u (or outside with a corresponding connection) a fan v is also arranged, the z. B. driven by a shaft w concentric to the shaft s. will. Through this fan v air, gas or steam can be forced into the interior of the drum or sucked out of the same.

Claims (1)

PATENTANSPRUCH: Vorrichtung zur Herstellung von Rohgummiplatten mit Fadeneinlagen nach dem Patent 42 1307, dadurch gekennzeichnet, daß unter Wegfall der Hohlachse eine Stirnseite der Trommel luftdicht abgeschlossen bleibt, während in oder an der anderen Seite ein Propeller oder Ventilator derart angeordnet ist, daß mit demselben der erforderliche Über- oder Unterdruck erzeugt werden kann. PATENT CLAIM: Device for the production of raw rubber sheets with thread inserts according to the patent 42 1307, characterized in that with the omission of the hollow axis, one end of the drum remains airtight, while in or on the other side a propeller or fan is arranged in such a way that with the same the required overpressure or underpressure can be generated.
