摘要:
A method of manufacturing an obliquely stretched long film includes an oblique stretching step and a tension application step. In the oblique stretching step, a long film is stretched in an oblique direction with respect to a width direction into a stretched film (F). In the tension application step, while the stretched film (F) is being drawn along a longitudinal direction, a tension in a drawing direction is applied to the stretched film (F). Here, in the tension application step, the tension in the drawing direction of the stretched film (F) is changed in the width direction, and thus the stretched film (F) is drawn.

The present invention provides a method for producing a long stretched film, including at least the steps of: forming a long film containing a thermoplastic resin; stretching the long film in an oblique direction; and winding the long film having been subjected to the oblique stretching. The oblique stretching is performed in a heating section including a preheating section, a stretching section, and a thermosetting section, the preheating section and the stretching section are separated from each other by a partition wall. The stretching section and the thermosetting section are separated from each other by a partition wall, each of the partition walls has an opening for permitting the long film to pass, and slide members independently movable on the opposite sides of the opening and in widthwise directions of the long film, the slide members can adjust the width of the opening and the widthwise position of the opening.

A method for producing a long stretched film according to one aspect of the present invention includes at least a step of forming a long film, a step of obliquely stretching the long film and a step of winding the long stretched film. A winding direction of the long stretched film can be arbitrarily changed to a direction oblique to a delivering direction of the long film. In the oblique stretching step, grip release points of gripping tools gripping opposite end parts of the long stretched film are independently movable in the winding direction of the long stretched film and so adjusted that a grip release line connecting the grip release points on respective opposite sides becomes parallel to the width direction of the long stretched film.
