Patent ID: 6905324

Claim:
Apparatus for producing a multilayered composite product comprising a coextrusion structure and a partition member, wherein said coextrusion structure is partitioned by said partition member into a first coextrusion substructure and a second coextrusion substructure, wherein said first coextrusion substructure comprises a first flow-shaping insert that comprises a transverse flow-providing manifold of a first flow-shaping channel wherein said first flow-shaping channel is in fluid communication with a first flow convergence channel, and wherein said second coextrusion substructure comprises a second flow-shaping channel in fluid communication with a second flow convergence channel, and downstream of and in fluid communication with said first flow convergence channel and said second flow convergence channel of said coextrusion structure, means for changing the relative orientation of a first flow stream and of a second flow stream to one another, comprising generally side-by-side inlets to a first flow-sequencing channel and a second flow-sequencing channel in fluid communication with an interface generating channel.
