Abstract

Embodiments of the presently-disclosed subject matter include extruder screws. Some embodiments of extruder screws include a screw body for placement in an extruder barrel, a plurality of ridges on the outer surface of the screw body that extend helically from an inlet end to an outlet end of the screw body, each adjacent pair of the ridges defining a channel, and one or more notches each extending across one of the plurality of ridges and between an adjacent pair of the channels. The notches can permit a material to flow from one channel into an adjacent channel, and the notches can define crosscuts that extend along the screw body and helically rotate in an opposite direction relative to the plurality of ridges. Furthermore, some extruder screws can further comprise one or more splitter rings.
