ABSTRACT:
The present invention provides a novel extrusion apparatus and process that are advantageous for converging rheologically dissimilar streams. Advantageously, stream convergence is effected proximate to the exit orifice to obviate or reduce the time migration effect. In an edge-laminating extrusion die in accordance with the invention, the width of an edge of an edge-laminated product may be mechanically defined.
