Abstract:
The present invention relates to an apparatus for manufacturing an optical film and more particularly, an apparatus for manufacturing a cellulose acylate film using a teflon coated roller which includes the teflon coated roller having a fluorine resin coating layer formed on the outer peripheral surface thereof and a steam jet cylinder for steam jetting thereby efficiently eliminating curls generated upon the manufacture of a cellulose acylate film.
