Abstract

Eine Extruderschnecke zur Verarbeitung von Material, insbesondere von Kunststoffen, mit einem Schneckenkörper (1), welcher einen Schneckenkern (2) aufweist, wobei um den Schneckenkern (2) mindestens zwei durch einen Barrieresteg (3) getrennte Schneckenkanäle (4, 5) angeordnet sind und wobei derart mindestens ein Feststoffkanal (4) und ein Schmelzekanal (5) gebildet sind, ist im Hinblick auf eine gute Aufschmelzleistung bei einfacher Konstruktion derart ausgestaltet und weitergebildet, dass im Feststoffkanal Mittel (6) zur partiellen Verringerung der Querschnittsfläche des Feststoffkanals (4) vorgesehen sind. Ferner wird eine Verfahrenseinheit gezeigt mit einer erfindungsgemäßen Extruderschnecke und mit einem Zylinder, in dem der Schneckenkörper (1) drehbar angeordnet ist, dadurch gekennzeichnet, dass im Zylinder und/oder im Barrieresteg (3) Nuten angeordnet sind.
