<p>The direction of orientation for a long inclined oriented film is inclined relative to the longitudinal direction and the direction of width. Let S1(m) be the length in the direction of width of a film (F) that includes the long inclined oriented film, and let Q(N) be the tension applied in the longitudinal direction to the film (F). In a state in which tension (Q) is applied to the film such that Q/S1 is 5 - 100 N/m, the film (F) is severed in the direction of width by a severing member (8a).</p> |
