Abstract
Die Erfindung geht aus von einem Extruder mit zwei Schnecken in zwei sich überlappenden, axial verlaufenden Bohrungen (2, 3) in einem Zylinder. Es wird vorgeschlagen, dass in dem in Förderrichtung des Extruders liegenden Endbereich des Zylinders sich an die Bohrungen (2, 3) ein Kanal (5) anschliesst, dessen Querschnittsform senkrecht zur Zylinderachse von der Form sich überlappender Doppelkreise in die Form eines einzigen Kreises übergeht.
