Abstract
PURPOSE: To obtain a film which has a stretching direction at a desired angle against a longitudinal axis thereof, by a method wherein a cylindrical film having a stretching direction in a longitudinal direction is produced, and it is formed into a long-sized sheet film by slitting it at a desired angle against the stretching direction thereof.
CONSTITUTION: A cylindrical film 8 having a stretching direction 9 in a longitudinal direction is produced by an inflation method. Slits 10 are made in the cylindrical film at a desired angle for extending the film into a long-sized sheet film 11. The stretching direction 9 is at a desired angle against the longitudinal axis of the long-sized sheet film.
