Abstract

A redistributing device for use with melt flow exhibiting boundary layer flow and centralized flow comprises a body including a melt flow inlet end and a plurality of melt flow outlets. A first flow diverter is included for distributing at least the boundary layer flow among the plurality of the melt flow outlets. A second flow diverter is included for distributing at least the centralized flow among the plurality of melt flow outlets.
