Verfahren zur Behandlung von vulkanisiertem Kautschuk und Vulkanit.
Um alten vulkanisierten Kautschuk und Vulkanit (Hartkautschuk) oder Abfälle dieser Materialien in einen Zustand überzuführen, in welchem sie wieder für die verschiedensten Zwecke Verwendung linden können, ist bereits vorgeschlagen worden, das zu verarbeitende Material

Nachdem der Boden des Zylinders mittels des Pfropfens c verschlossen worden ist. wird der zermahlene oder in kleine Stücke zerschnittene Kautschuk in den Zylinder eingebracht und der Pfropfen b teilweise in das obere Ende desselben eingeführt. Inzwischen wird an das Rohr d eine Saugpumpe angeschlossen und die Luft abgesogen. Zum Erhitzen des Zylinders kann heisser Sand oder eine sonstige geeignete Wärmequelle dienen.
Auf den oberen Pfropfen b kann mittels einer Schraube ein entsprechender Druck ausgeübt werden, durch welchen der genannte Pfropfen allmählich auf die Kautschuk-

Es wurde gefunden, dass sich unter Anwendung von Vakuum vulkanisierter Kautschuk lind Hartkautschuk bei Temperaturen von etwa 150-200 C derart erweichen lassen, dass die genannten Materialien durch entsprechenden Druck oder ähnliche Behandlung zu Blöcken,

Process for treating vulcanized rubber and vulcanite.
In order to convert old vulcanized rubber and vulcanite (hard rubber) or waste of these materials into a state in which they can be used again for a wide variety of purposes, it has already been proposed to use the material to be processed
EMI1.1
the mass is agglomerated and freed from the air-filled cavities by pressing. to shape again accordingly.
EMI1.2
Rubber and vulcanite present in new forms is due to the presence of atmospheric air in the material to be processed.
This air offers a mechanical resistance to the pressure-induced unification of the said material into a uniform mass and, moreover, has the tendency to initiate and maintain the combustion of the material when heat is applied to soften it.
EMI1.3
the air is sucked out during his treatment to make it easier.
In order to explain the subject of the invention, the drawing shows a

pipe. through which the air can be sucked out of the cylinder a. After the bottom of the cylinder has been closed by means of the plug c. the rubber, crushed or cut into small pieces, is placed in the cylinder and the plug b is partially inserted in the upper end of the same. In the meantime, a suction pump is connected to pipe d and the air is sucked off. Hot sand or another suitable heat source can be used to heat the cylinder.
A corresponding pressure can be exerted on the upper plug b by means of a screw, by means of which the said plug gradually acts on the rubber

as a homogeneous elastic block out of shape.
It has been found that by using vacuum vulcanized rubber and hard rubber can be softened at temperatures of about 150-200 C in such a way that the mentioned materials by appropriate pressure or similar treatment to form blocks,
