ABSTRACT:
In order to provide adaptability to a variety of material properties in a worm feed extruder for processing of synthetics or rubber, individual feed worm segments (7) and cylinder segments (10) surrounding the feed worm segments are provided at desired locations, the feed worm segments and cylinder segments being constructed divisible in the axial direction to enable these feed worm segments to be exchanged for feed worm segments of differing geometry. Removal of the cylinder (2, 3) or withdrawal of the feed worm (1) from the cylinder is thus avoided in the case where the feed worm is to be adapted to various material properties.
