    摘要： A film (F) is transported with one end side in a width direction moved relatively in a preceding manner and the other end side moved relatively in a delayed manner and thus the film (F) is stretched in an oblique direction with respect to the width direction. In the individual positions of the film (F) in the width direction, the film (F) is asymmetrically heated in the width direction such that the amount of displacement (ΔL) of an orientation angle from a desired angle caused by bowing (Bo) asymmetrically produced in the width direction by the stretching of the film (F) in the oblique direction is reduced, and thus a maximum value in the temperature distribution of the film (F) is present between a center portion in the width direction and any one of end portions.

    摘要： A method for producing obliquely stretched long film comprises an oblique stretching step and a folding step. In the oblique stretching step, a long film is stretched in the oblique direction with respect to the widthwise direction to create a stretched film (F). In the folding step, while conveying the stretched film (F) after stretching, the stretched film (F) is folded back at least once on the inner face thereof in a direction parallel or perpendicular to the stretching direction.
