Abstract
Using a balanced flow path, multiple layers of extruded plastic are supplied to a chamber having independently rotating surfaces. Said rotating surfaces apply a shear force to at least the inner and outer layers of said extruded plastic to orient said materials in said layers in different helical patterns, thereby forming a multi-layer tubular product in which at least inner and outer layers have different helical patterns to strengthen the product.
