Abstract

See full text

A method of forming a conduit having at least one strip-shaped fabric substrate dividing the conduit into channels. The method contains obtaining an extrusion die configured to form the wall of the conduit and a slot configured for receipt of a strip-shaped fabric substrate and introducing a strip-shaped fabric substrate into the slot. The strip-shaped textile is air permeable and contains enlarged regions at the first and second longitudinal edges. Molten polymer is introduced at a first point in the extrusion die and at the first point the slot and the area configured to form the wall of the conduit are not in communication. The slot is exposed to the molten polymer at a point between the first point and the die exit forming the first polymeric layer of the conduit such that the first longitudinal and second longitudinal edges of the strip-shaped fabric substrate embed into the molten polymer.
