Abstract

PURPOSE:To manufacture a thermoplastic resin film with slight thickness unevenness, by driving a arum for cooling the molten film with a specific modor to reduce the variation in rotation of the drum. CONSTITUTION:A thermoplastic resin is molten and extruded through a die into a film, which is charged electrostatically, cooled and solidified by a rotating drum. The drum is directly driven by a motor having a brake torque controlled at any given constant speed with a speed control unit without using a mechanical reduction gear, thus maintaining the instantaneous variation in rotation of 1% or below.
