摘要：
A film elongating method, a film elongating device and a solution casting method are provided to give the retardation to a required surface while controlling non-uniformity of the retardation in the surface in a width direction. An elongating process is performed in a TAC film(3) by a tenter part(5). The side edge of the TAC film is slit by a slitting part(12). The slit edge of the TAC film is cut by a cut blower(13). The TAC film is heat-processed by a release chamber(6) for reducing the stress. The TAC film is cooled down below 30 degrees centigrade by a cooling chamber(7). The TAC film is pressed and wound around a winding roller by a winding chamber.
摘要（中）：
提供薄膜延伸方法，延伸膜和溶液流延法，以便在宽度方向上控制表面的延迟的不均匀性，从而给所需表面提供延迟。 通过拉幅机部件（5）在TAC膜（3）中进行拉伸加工。 通过切割部分（12）切割TAC膜的侧边缘。 通过切割鼓风机（13）切割TAC膜的狭缝边缘。 TAC膜通过用于减小应力的释放室（6）进行热处理。 通过冷却室（7）将TAC膜冷却至低于30摄氏度。 通过卷绕室将TAC膜按压卷绕在卷绕辊上。
