Abstract

Extrudereinrichtung mit einem Doppelschneckenextruder (1) mit zwei gleichsinnig drehenden und miteinander kämmenden Schnecken (2, 2 '), die in einem die beiden Schnecken umschließenden Gehäuse (5) aufgenommen sind, wobei das Gehäuse zwei entlang der Längsachse des Doppelschneckenextruders sich überlappende Bohrungen zur Aufnahme der Schnecken aufweist. Die Erfindung zeichnet sich dadurch aus, dass das vordere Ende des Doppelschneckenextruders um wenigstens ein Einschneckenextruder-Element (3) verlängert ist, wobei ein als Förderschnecke ausgebildetes Verlängerungsstück einer der Schnecken des Doppelschneckenextruders in einem die Förderschnecke umschließenden Gehäuse aufgenommen ist, derart, dass das von den beiden gleichsinnig drehenden und miteinander kämmenden Schnecken geförderte und an das Einschneckenextruder-Element übergebene Material durch Rotation der verlängerten Schnecke des Doppelschneckenextruders von der Förderschnecke des Einschneckenextruder-Elements ohne Ausbildung eines signifikanten Rückstaus in dem Doppelschneckenextruder abtransportiert und in dem oder den Schneckengängen des Einschneckenextruder-Elements nach und nach ein Füllgrad von 100% erreicht werden kann.
