Abstract
An extrusion apparatus is provided having an extrusion worm with a threaded exterior passage and rotatably driven by a drive shaft operatively couplable with a drive motor for driving rotation of the drive shaft. A feed in device feeds to the extrusion apparatus material that is to be extruded. The extrusion device includes a socket having a threaded interior passage, the socket receiving therein the extrusion worm in at least partial axial overlap such that material to be extruded passes between and in contact with the threaded exterior passage of the extrusion worm and with the threaded interior passage of the socket. The rate of rotation of the socket and the rate of rotation of the extrusion worm are independently adjustable relative to one another.
