Abstract

PURPOSE:To make a band for packing etc. with uniform weight and width by a method in which the thermoplastic resin extruded at molten state from an extruder, is cooled to drawable temperature and is drawn without heating by a simple apparatus. CONSTITUTION:An extruded article A extruded from the nozzle 2 of an extruder 1, is cooled to the drawable termperature lower than the crystallization temperature in a cooling tank 5. Then water is sprayed on both sides of the extruded article A from a water supply port 3 so that the inferior on the resin surface due to boiling of water may be prevented. Further, a half circle-grating 4 is used instead of roll to prevent the wrinkles or surface inferior of the resin. Next, the extruded article A is drawn between a pinch roller 7 and a drawing roller 8. By the heat generation of the resin at the drawing, the temperature of the article A is elevated above the temperature before drawing, and the strain in the resin is removed at an annealing section 9. Next, the article A is received by roller 11 and is wound up by a coiler 12 after the article A is cooled in a cooling tank 100.
