Solution casting method and polymer film |
| abstract |
Side edge portions of a film in which a content of a remaining solvent is at least 30 wt. % are contacted to side parts of first-third rollers with suctioning through suction ducts. Thus a middle portion between the side edge portions is not contacted to the rollers, and the film is transported toward a tenter device in accordance with the rotation of the rollers. In the rollers, each side part of the rollers has a larger diameter of a middle part. At least one of intervals between the neighboring rollers is from 1 mm to 200 mm, and the lapping angle is from 1° to 180°. Toward the middle part of the film, and air is fed in a roller side. The obtained film doesn't have any neither crumples, wrinkle, curl and the like, and foreign materials are hardly adhered. Therefore the continuous film production can be made stably. |
