    摘要： A method for manufacturing a wide film comprises a casting operation, a stretching operation, and a trimming operation. The casting operation is a process of casting a film using a wide casting belt including a central belt, a left belt having a right end formed integrally with a left end of the central belt through a left joint in a length direction of the central belt, and a right belt having a left end formed integrally with a right end of the central belt through a right joint in the length direction of the central belt. The stretching operation is a process of stretching a film stripped off from the wide casting belt using a tenter. The trimming operation is a process of trimming predetermined parts of left and right sides of the stretched film. In the trimming operation, mark parts by the left and right joints are also trimmed.
