A redistributing device for use with melt flow exhibiting boundary layer and centralized flow, comprising:
- a body including a melt flow inlet end and a plurality of melt-flow outlets, said body engaging a melt flow channel;
- first means in said body for distributing at least said boundary layer among said plurality of melt flow outlets;
- second means in said body for distributing at least said centralized flow among said plurality of melt flow outlets;
- wherein said body has a central opening therein defining a central flow channel in fluid communication with said outlets comprising said second means for distributing, and said first means for distributing comprises inlets leading to a plurality of diverters positioned on said body and adjacent said opening, said diverters extending from said inlet end and into fluid communication with said plurality of melt-flow outlets,
- wherein the material flowing in the central channel meets the material flowing in the diverters and emerges at the outlets.
