Abstract
Side by side extruders provide an extrusion apparatus which has an imposed order of longitudinal displacement of the process material in relation to itself so that cross-shearing is directed to newly aligned material in a manner which achieves volumetric blending with little unproductive shearing. The extrusion apparatus mixes and extrudes polymer like materials with as little waste shearing as possible, so as to preserve the viscosity of the polymer materials and to produce a uniformity processed material of the highest quality possible from the starting materials.
