    摘要： A venting section in an extrusion device for venting volatile elements from an extrudate, such as a plastic material, which venting section comprises a plurality of venting segments shaped to alternately compress and decompress said extrudate so as to free from the bulk of the plastic material said volatile elements which can then be carried away by a vacuum system through suitable vent openings formed in the barrel enclosing said venting section.
