Abstract

PURPOSE:A molten tube of synthetic resin is extruded horizontally from a annular orifice and is cooled by blowing a gas from a cooling ring. Simultaneously the gas on the outer periphery of the tube is removed by sucking, thus enabling the highspeed production of tubular films and the contraction of cooling zone.
