METHOD AND APPARATUS FOR MANUFACTURING RESIN SHEET |
摘要 |
PROBLEM TO BE SOLVED: To provide a method and an apparatus capable of stably manufacturing a resin sheet, especially, a thin resin sheet with a thickness of 0.06 mm or less without generating spark discharge by rationalizing the position of a wire electrode with respect to a cooling drum. SOLUTION: The method for manufacturing the resin sheet cools and solidifies the sheetlike molten resin extruded from a slit die by a moving cooling medium while applying static charge thereto by the use of a wire electrode. The distance from the wire electrode to the moving cooling medium is set to 3 mm or less to apply static charge to the sheetlike molten resin.
