Abstract

Process for the manufacture of clear and thick wall tubes of polyethylene terephthalate characterized by forming a tubular body extruded by melting said polyethylene terephthalate at a melting temperature of 260 to 310ºC and solidifying the extruded body thus shaped to mold a tube by cooling said extruded body from the outside; by passing it in direct contact with an outer calibration sleeve through which a fluid circulates at a temperature of -7º to 15ºC while, simultaneously, said extruded body is cooled from the inside, passing it axially on an internal cooling mandrel through which a fluid circulates at a temperature of -7º to l5ºc.
