Summary:Mixing characteristics of an elastic melt extruder are improved by providing, in the opposing, spaced-apart walls of a rotor and a stator, shaped recesses arranged annularly about the axis of rotation. During processing, the visco-elastic material, generally travelling radially inward between the wall surfaces of the rotor and the stator, is accelerated into the recesses and mixed together before it is caused to move in toward the center of the gap and continue its radial inward movement with the mass of material.
