Abstract

L'invention concerne les appareils de formation de films de matière plastique. Elle se rapporte à un appareil dans lequel le film extrudé 14 est fendu par un couteau 32 si bien qu'un tube 26 peut passer par l'orifice formé et peut alimenter un tube diffuseur 22 qui fait circuler de l'air de refroidissement à l'intérieur du film 14, l'air s'échappant par l'orifice formé dans le film. Application à la fabrication des films de polyéthylène et de polypropylène.
