Abstract
Die apparatus configured for forming corrugated pipe from thermoplastic material in association with transported wall mold sets defining a wall forming tunnel. The apparatus employs two homogenizer stations, a first at its entrance for providing homogenized material to an outer wall delivery channel extending to an outer wall extrusion nozzle. Plastic material is delivered under pressure along a heated internally disposed extender pipe to a liner homogenizer stage located downstream and feeding a liner extrusion nozzle. An access region is made available between the outer wall extrusion nozzle and the liner extrusion nozzle.
