    • Disclosed herein is a cooling/guiding method and a cooling/guiding apparatus that will be used when a film of a thermoplastic synthetic resin or the like is to be produced by the inflation method or the T-die method.According to the invention, a thermoplastic synthetic resin film is continuously passed through a section constituted by a single or a plurality of air-introducing members having air intake ports, the air surrounding said film is vacuumed by said air-introducing members so that the pressure differential imparted to the film is balanced, and the film is guided into a predetermined path under the condition where the film is separated away from the air-introducing members.Therefore, the apparatus cools and guides the film without coming into contact thereto, and without cooling the film irregularly and without marring the film, making it possible to markedly increase the film-forming speed and quality of the film.
    • 这里公开了当通过吹塑法或T模法制造热塑性合成树脂等的膜时将使用的冷却/引导方法和冷却/引导装置。 根据本发明,热塑性合成树脂膜连续地通过由具有进气口的单个或多个空气引入部件构成的部分,所述膜周围的空气被所述空气引入部件抽真空,使得压力 平衡赋予薄膜的差别,并且在薄膜与空气导入构件分离的状态下将薄膜引导到预定路径。 因此,该装置冷却并引导膜而不与其接触,并且不使膜不规则地冷却并且不会损坏膜,使得可以显着提高膜的成膜速度和质量。
