ABSTRACT:
A pin-barrel extruder suitable for processing rubber and thermoplastic plastics materials having pin adjustment means is disclosed. The extruder comprises a barrel having a screw rotating therein. Pins project radially inwardly into the hollow interior of the barrel. These pins are distributed both uniformly around the periphery of the barrel and in axial alignment with one another. Axially aligned pins are made adjustable, with regard to their depth of penetration into the barrel by being connected to a bar or rail. This bar or rail is disposed radially outwardly of the barrel but extends parallel to the axis thereof. Actuating means are provided for displacing the bar or rail, and hence the pins, relative to the barrel.
