Abstract
Bei einem Verfahren zur Entnahme von Produktproben aus dem Prozeßraum eines Extruders, wird ein in dem Gehäuse oder in einem Gehäusemodul (1) des Extruders vorgesehener, von dem Prozeßraum (2) ins Freie führender Auslaßkanal (3) durch Zurückschieben eines längs der Achse des Auslaßkanals (3) verschiebbaren Profilverschlußkolbens (4) geöffnet, so daß eine Produktprobe (7) durch eine in dem Prozeßraum (2) vorgesehene Auslaßöffnung (8) in den Auslaßkanal (3) gedrückt wird. Sodann wird mittels eines Ausstoßkolbens (6), der in einem den Auslaßkanal (3) kreuzenden Ausstoßkanal (5) geführt ist, die Produktprobe (7) ins Freie gedrückt.
