METHOD AND DEVICE FOR MANUFACTURING SYNTHETIC RESIN TUBE

摘要

PROBLEM TO BE SOLVED: To improve working accuracy of a synthetic resin tube. SOLUTION: In the method for manufacturing a synthetic resin (corrugated) tube 50 wherein a molten resin is extruded from an extruder 10 into a molding machine 20 to form a tube body r2 from the molten resin by means of the molding machine 20 and the tube body delivered from the molding machine is sent into a cooling tank 30 to cool it, the tube body delivered from the molding machine is directly fed into the tank 30 obliquely downwarclly with respect to the liquid level of a cooling liquid W in the tank.
