ABSTRACT:
An apparatus for continuously extruding shaped articles includes 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, a conduit for directing extruded material from the holding chamber to each die chamber for selectively filling each die chamber with extruded feed material and a monitor for filling of each die chamber of said plurality of die chambers with extruded feed material. The conduit is responsive to the monitor 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.
