ABSTRACT:
Two movable die members that are situated opposed to each other in an extrusion die assembly, the axis of movement of the two die members is parallel to the longer sides of the rectangular cross-section of a throat opening of the extrusion die assembly. The members move in a reciprocating back and forward movement to impart shearing forces to the surface of the extruded material with a resultant multiaxial orientation of the molecules or fibrils.
