Abstract: An extrusion device for producing an article of a heterogeneous blend of incompatible polymers, one polymer forming a matrix and the other being in a discontinuous phase within the matrix. The device is used with either side-fed or center-fed multiple parison die heads. The desired heterogeneous resin structure is formed and maintained by a unique extrusion screw and adapter configuration that avoids division of the melt stream to feed the multiple parison die head after formation of the desired resin structure. This is accomplished by a plurality of arcuate flow passages in the terminal portion of the extrustion screw directly feeding each die. The arcuate flow passages are formed by ribs that extend radially inwardly from the extruder barrel toward a flightless terminal portion of the screw shaft and tip. Circulatory resin flow in the arcuate flow passages driven by the screw rotation forms the desired laminar resin structure.
