 man den Zeitpunkt, zu welchem das Abgiessen beendet worden soll, leicht beurteilen. Durch das kräftige   Durcheinandermischen   mittels der Knotflügol wird die Kautschukmasse in körnigen Zustand gebracht. Die Welle 6 der Knetvorrichtung wird nun angehalten und die Pumpe 10 in Tätigkeit versetzt, welche dazu dient, die letzten Spuren des Lösungsmittels aus der körnigen Masse zu entfernen. Hiebei ist es vorteilhaft, den Behälter 1 zu erwärmen. 



   Der Verdampfer 12 ermöglicht die   Rückgewinnung   de verwendeten Hilfsflüssigkeiten in sehr kurzer Zeit, nachdem sich diese Flüssigkeiten infolge der Verschiedenheit ihrer Siedepunkte leicht voneinander abscheiden und die Dämpfe im Kondensator 16 kondensiert werden. Die wiedergewonnenen Flüssigkeiten werden durch entsprechende Betätigung von Hähnen in die zugehörigen Behälter 7 und 8 eingeleitet. Die Harze verbleiben in dem Behälter 12 und werden aus diesem entfernt. Im Verhältnis zur harzreichen Masse, die behandelt werden soll, wird nur eine geringe Menge Flüssigkeit benötigt. Auch ist die vollständige Wiedergewinnung der in der   Kautschukl1lasse   enthaltenen Lösungsmittel gesichert, so dass das Verfahren nicht nur durch eine rasche, sondern auch wirtschaftliche Behandlung der Ausgangsprodukte ausgezeichnet ist.

 you can easily judge the point in time at which the pouring should be stopped. Vigorous mixing with the Knotflügol brings the rubber mass into a granular state. The shaft 6 of the kneading device is now stopped and the pump 10 is activated, which serves to remove the last traces of the solvent from the granular mass. It is advantageous here to heat the container 1.



   The evaporator 12 enables the auxiliary liquids used to be recovered in a very short time, after these liquids easily separate from one another due to the difference in their boiling points and the vapors are condensed in the condenser 16. The recovered liquids are introduced into the associated containers 7 and 8 by actuating taps accordingly. The resins remain in the container 12 and are removed therefrom. In relation to the resin-rich mass that is to be treated, only a small amount of liquid is required. The complete recovery of the solvents contained in the rubber class is also ensured, so that the process is distinguished not only by a rapid but also economical treatment of the starting products.



   PATENT CLAIMS:
1. A method for cleaning raw rubber by means of resin-dissolving liquids, characterized in that the raw material is replaced by small amounts of a rubber substance prior to extraction.
