Abstract

The cylinder housing the extrusion screw carries a sleeve which is split longitudinally and with straight or helical grooves running into collector chambers each end. Outside these grooves are peripheral holes for heating elements. A number of sleeves may be connected, each supplied with air at the inlet channel, and exhausting at the outlet channel. The sleeve may be finned.
