Abstract
A flow diverter for an extrusion die is disclosed. The flow diverter includes a body having an outer surface, an elongate opening that extends along a first axis, a set of input passages that extend from said outer surface through said body to said elongate opening, and a set of output passages that extend through said body from said elongate opening to said outer surface. The flow diverter also includes an adjustable valve positioned in said elongate opening. The adjustable valve also has a monolithic spool including a first recess and a second recess opposite to said first recess. The spool is rotatable with respect to said outer body between a first position in a first flow configuration, and a second position in a second, different flow configuration.
