    • PURPOSE: An optical film manufacturing device including a guide plate and a method for manufacturing an optical film using the guide plate are provided to prevent a bubble on both edge parts of the casting film by installing an upper dry unit and a lower guide plate. CONSTITUTION: A first rotation unit and a second rotation unit are separated from each other. A casting belt(120) is wound around the first and second rotation units and is cast with a dope including a polymer solution on the upper side of an upper driving unit. A lower dry charging duct(311) is installed on the lower side of a lower driving unit(122) of a casting belt to dry the casting film and includes a warm air outlet. A lower guide plate is installed along the driving direction of the lower driving unit on the lower side of an inner side of both edges of the lower driving unit of the casting belt to guide the warm air discharged from the lower dry discharge duct.
    • 目的:提供一种包括引导板和使用该引导板制造光学膜的方法的光学膜制造装置,以通过安装上部干燥单元和下部引导板来防止流延膜的两个边缘部分上的气泡。 构成:第一旋转单元和第二旋转单元彼此分离。 铸造带(120)缠绕在第一和第二旋转单元周围,并且在上部驱动单元的上侧用包含聚合物溶液的涂料浇铸。 较低的干燥充气管道(311)安装在铸造带的下部驱动单元(122)的下侧以干燥流延膜并且包括温暖的空气出口。 沿着下侧驱动单元的驱动方向,在下侧驱动单元的内侧的内侧的下侧安装下引导板,以引导从下部干式排出管排出的暖空气。
