ABSTRACT:
A plastifying extruder of the double-screw type, to avoid dead zones in the flow, has at its throttle location throttle disks on the screws formed with outwardly open recesses angularly equispaced on the disks. Pins distributed around the screws in the throttle region project radially into gaps between the disks and can penetrate to a greater or lesser extent into these gaps to provide a variable flow cross section.
