Abstract

PURPOSE: To uniformalize the thickness in the direction of width by blasting cooling air on a film when it is calendered for forming.
CONSTITUTION: On the occasion that thermoplastic resin material 5, for instance, is rolled between rolls 11W14 sequentially to be formed into a film, air is blasted on the thinner part of the film for cooling in front of a point B where the film exfoliates from the final calender roll 14 by an air blasting device 3 provided along the direction of the width of the film, and then the film is taken over by take-over rolls 2.
