| 20090020922 | PRODUCTION METHOD OF POLYMER FILM AND PRODUCTION APPARATUS OF THE SAME - A dope is cast onto a casting drum from a casting die while forming a casting bead. Oxygen concentration at the vicinity of the casting bead is set to 0 vol % or more and less than 10 vol %, and a static electricity applying electrode applies static electricity between the casting drum and the casting bead. An intervening film forming device supplies intervening film forming liquid onto the casting drum to form an intervening film. A compression chamber decompresses a downstream area from the casting bead. Thereby, it is possible to form the casting bead having a stable shape, and enhance the extent of adhesion between a casting film and the casting drum. Accordingly, it is possible to enhance the extent of adhesion between the casting drum and the casting bead, prevent occurrence phenomenon of air entrainment, and speed up a film forming speed, thus forming a polymer film. | 01-22-2009 |
