  A method of producing a long roll retardation film comprising the sequential steps of: (a) casting a film forming material on an endless support to form a long roll film; (b) stretching the long roll film in a lateral direction of the long roll film while both edges of the long roll film are held employing a plurality of clips for each of the edges in a tenter (First Process); (c) reducing distances in the lateral direction between the clips holding the both edges of the long roll film while the edges of the long roll film are held continuously from First Process with the clips (Second Process); (d) enlarging the distances in the lateral direction between the clips holding the both edges of the long roll film while the edges of the long roll film are held continuously from Second Process with the clips (Third Process).

  一种制造长卷延迟膜的方法，包括以下步骤：(a)在无限支撑上铸造成膜形成材料，形成长卷膜;(b)在张力机上用多个夹子夹住长卷膜的两个边缘，沿长卷膜的横向方向拉伸长卷膜（第一步骤）;(c)在第一步骤中，保持夹子夹住长卷膜的两个边缘，同时减小夹子之间的横向距离（第二步骤）;(d)在第二步骤中，保持夹子夹住长卷膜的两个边缘，同时增大夹子之间的横向距离（第三步骤）。
