SHEET/FILM MOLDING APPARATUS AND SHEET/FILM MOLDING METHOD |
摘要 |
A sheet/film molding apparatus includes: a main roll sandwiches and presses, with a touch roll, a resin molten sheet and conveys the sandwiched and pressed resin sheet; and a separating roll separates the resin sheet from an outer peripheral surface of the main roll and conveys the resin sheet. The separating roll has a rubber roll and a metal elastic external cylinder having the rubber roll housed therein and being eccentrically positioned to the rubber roll and thin and easily elastically deformed. Cooling water is supplied between the rubber roll of the separating roll and the metal elastic external cylinder. The resin sheet between the main roll and the metal elastic external cylinder is cooled by allowing the rubber roll to make pressure contact with an inner peripheral surface thereof. The separating roll separates the resin sheet from the outer peripheral surface of the main roll.
