    摘要： In an aspect of the present invention, since the maximum linear pressure when a sheet-like melted resin is nipped between an elastic roller and a cooling roller is controlled at 0.3 MPa to 3 MPa, the development of retardation in film forming can be prevented. According to the aspect, since an elastic roller and a cooling roller are rotated at nearly the same speed with the periphery speed ratio thereof at 0.99 to 1.01, a sheet-like melted resin can be transported without applying a stress caused by a rotation difference between the rollers, whereby the development of retardation on the unstretched thermoplastic resin film can be prevented. Further, since the surface temperature of a cooling roller is controlled so as to be 0.01° C. to 30° C. higher than that of an elastic roller, a sheet-like melted resin is pulled toward the elastic roller side, whereby the development of retardation can be prevented.

    摘要翻译： 在本发明的一个方面中，由于将片状熔融树脂夹在弹性辊和冷却辊之间的最大线性压力控制在0.3MPa至3MPa，因此可以防止成膜时的延迟发展。 根据本发明，由于弹性辊和冷却辊以其周边速度比以几乎相同的速度旋转为0.99至1.01，所以片状熔融树脂可以在不施加由两者之间的旋转差引起的应力的情况下传送 因此能够防止未拉伸热塑性树脂膜的延迟的发展。 此外，由于将冷却辊的表面温度控制为高于弹性辊的表面温度为0.01℃至30℃，因此片状熔融树脂被拉向弹性辊侧，由此显影 可以防止延迟。
