A method and apparatus for the extrusion of multilayered composite products,
is
provided. The inventive apparatus includes a coextrusion structure and a partition
member. In accordance with the inventive method, the relative orientation of a
first shaped flow stream and a second shaped flow stream to one another is changed,
and the reoriented shaped streams are melt-laminated to produce a layered composite
formed independent of division of a layered precursor stream. The reorientation
occurs via a flow sequencer, which may be removably disposed. Beneficially, layered
flow streams that differ from one another may be used. The coextrusion structure
may advantageously include one or more removably disposed, flow-shaping inserts,
and the partition member may be a removably disposed, partition plate.
