<p>An extrusion apparatus (10) includes a die (12) and a combining adaptor (14) inserted in a cavity in the die (12). The extrusion apparatus (10) includes flow channels (16, 18) which converge in the proximity of a locus (48) at which a layered melt stream, formed by the convergence, is caused to diverge and flow transversely. The locus of divergence (48) is within a manifold (46). The apparatus can be used to make a laminate having layers of substantially uniform thickness, without profiling of the layered melt stream.</p> |
