    • A casting unit, a dope applying method, and a solution casting method are provided to manufacture an optical functional film having a uniform thickness by adjusting a thickness of a lateral portion of a casting bead. A dope applying method comprises the steps of preparing a side dope(51a) for constituting a side portion of a bead(80) from a casting die(81), which discharges the side dope through a slit(126) extending in a widthwise direction of a support, preparing a middle dope(51c) for constituting a middle portion between the side portions of the bead, joining flows of the side dopes and the middle dope in the casting die having a partitioning member(140) formed with a cutout section so that the partitioning member forms a side flow passage for flowing the side dope and a middle flow passage for flowing the middle dope, and making a co-application of the side dopes and the middle dope.
    • 提供铸造单元,涂布方法和溶液流延法,通过调节铸造珠的侧面部分的厚度来制造具有均匀厚度的光学功能膜。 涂布方法包括以下步骤:从铸模(81)制备用于构成珠粒(80)的侧部的侧面涂料(51a),其通过沿宽度方向延伸的狭缝(126)排出侧部涂料 的支撑体,制备用于构成胎圈的侧部之间的中间部分的中间涂料(51c),在具有形成有切口部分(140)的铸模中连接侧涂料和中间涂料的流动 使得分隔构件形成用于使侧面涂料流动的侧流通道和用于使中间涂料流动的中间流动通道,并且使侧涂料和中间涂料共同施用。
