    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.

    摘要: A method for producing a long stretched film according to one aspect of the present invention includes at least a film forming step of forming a long film made of thermoplastic resin, an oblique stretching step of obliquely stretching the long film and a winding step of winding the long stretched film after the oblique stretching step. The oblique stretching device includes gripping tool travel support tools at opposite sides of the traveling long film. Each of the gripping tool travel support tools includes a plurality of gripping tools. In the oblique stretching device, the gripping tool travel support tools provided at the opposite sides of the long film include the same number of gripping tools. A combination of the gripping tools forming a gripping tool pair is constantly the same at grip start points where the long film is gripped by the gripping tools.

    摘要: 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.
