CONTINUOUS EXTRUSION OF COMPLEX ARTICLES

摘要

An apparatus (20) for continuously extruding shaped articles includes a frictional extrusion source for extruding a feed material (31), a chamber for holding (42, 43) frictionally extruded material received from the extrusion source, a plurality of die chambers (10, 10a), each of the die chambers (10, 10a) receiving extruded material from the holding chamber (42, 43), a conduit (44, 45) for directing extruded material from the holding chamber (42, 43) to each die chamber (10, 10a) for selectively filling each die chamber (10, 10a) with extruded feed material and a monitor (53) for filling of each die chamber (10, 10a) of said plurality of die chambers with extruded feed material. The conduit (44, 45) is responsive to the monitor (53) so that extruded material can be directed from a filled die chamber (10, 10a) to an empty die chamber (10, 10a) for subsequent filling, thereby permitting continuous extrusion.
