。Detailed Description of the Invention: a. Field of Industrial Application The present invention relates to a film slitting method, and more specifically, to an improvement of a slitting method in which a raw film such as a synthetic resin film is cut and wound into a plurality of narrow film rolls. Regarding.

断することが行なわれている。b6 Purpose of the Invention Conventionally, when slitting synthetic resin films such as polyester films, the tension was controlled while unwinding the film from a wide roll of raw material and transporting it with rollers, etc.
In addition, the film is expanded in its width direction using a curved roller that rotates around a curved axis called an expander, or a device called a flat expander that uses the expansion and contraction of special rubber on a horizontal roll surface, and then the desired slit width is formed. Judgment is being done.

がある。However, this method has the problem that the film is not sufficiently widened and the width of the cut film varies. On the other hand, in recent years, a method has been proposed in which the tension of each cut film is individually controlled when winding thin films that are difficult to roll up, or films that are easy or non-slip. There is a problem in that a movement occurs in the running tension and it is difficult to control the winding tension.
本発明はこのような問題を解決覆るスリット方法を提供
するものである。The present invention provides a slitting method that solves these problems.

The material is guided by the material and expanded in its width direction to remove wrinkles and shrinkage. As the expansion roller 7, any expansion roller such as a curved rotating roller or a flat expander that utilizes rubber expansion and contraction can be used as described above. 8 is expansion roller 7
It is a nip roller installed immediately after the Ic roller whose surface is lined with rubber, and the raw film immediately after being expanded is held between the Ic rollers, and the film from which wrinkles and shrinkage have been removed is fixedly covered in that state for 10 days. It is transferred to the cutting section 9 which is the next process. The cutting section 9 consists of a cutting roller 9a, a cutter 9b, etc.
Cut the original film into multiple narrow films. The cut narrow-width film is wound into a film roll by a winding device 10 provided individually for each film, with the tension angle controlled for each film.

。d1 Effects of the invention In the present invention, immediately after the original film is expanded with an expansion roller, the entire width of the film is once nipped and cut, which eliminates tension irregularities in the width direction and stabilizes the cutting width of the film. , stable cutting is possible, and the tension of each narrow-width film after cutting is constant and stable.Especially when controlling the tension of each narrow-width film to perform precise winding, the tension of each film can be adjusted. The sixth point is that fluctuations in the winding speed are reduced, contributing to stable roll winding.

However, the method of the present invention is not limited to this winding method, and can be applied to other winding methods. It is also useful in the case of
