ABSTRACT:
An apparatus for continuously extruding shaped articles includes providing a frictional extrusion source for extruding a feed material, a chamber for holding frictionally extruded material received from the extrusion source, a plurality of die chambers, each of the die chambers receiving extruded material from the holding chamber, means for directing extruded material from the holding chamber to each die chamber for selectively filling each die chamber with extruded feed material and means for monitoring filling of each die chamber of said plurality of die chambers with extruded feed material. The directing means is responsive to the monitoring means so that extruded material can be directed from a filled die to chamber to an empty die chamber for subsequent filling, thereby permitting continuous extrusion.
