Description

464 60 9 V. Description of the invention (i) Background of the invention 1. Field of the invention The present invention relates to a film manufacturing apparatus and a film manufacturing method, which are steps for manufacturing a film for use in a steel sheet covered with a resin film. In addition, by using a film width adjustment device that can change and adjust the width and thickness of the film by enlarging the film, the target width and thickness of the film are achieved at the same time, so that not only the number of cuts of the film is reduced, and thus the yield ratio is enhanced. It can also control the thickness of the film in the maximum extrusion amount of the film, and thus enhance its productivity. 2. It is well-known that the words of the head and mouth giller hall, in order to match the width of a film to be manufactured to the target width, and the yield ratio of the strengthened film, implement a For example, the method of the width of the exit of the extrusion machine of a T-die to thereby reduce the protruding waste of the film, and a remaining portion of the film material that is used to cut off the width of the product (film) and recycle Use the method that was cut off. However, in the former method of adjusting the exit width of the T-die in the manufacturing of the film, thereby reducing the waste of the protruding portion of the film, two main problems have been found: namely, first, the film material leaked from the film width adjusting portion Increase the waste of the film; and another problem is that the turbulent flow of the film material in the film width adjustment part will cause the bad shape of the film and cause the quality of the product (film) to deteriorate. In view of the aforementioned problems found in the former method, the latter method is generally used. However, when two or more kinds of films are used, they are laminated on each other.

The ratio at which the resulting product becomes second or processed. In addition, the increase in the number of film materials and the increase in the number of cut-offs are large, and it is difficult to strengthen the more layers of the film in the case of qualitative changes, so that it is not in the wide cut-off number of the product (thin), making it not Greatly increase the production of products (thin ^, all cut-off parts are not productive. Inventive invention, the material of the film may be strengthened through recycling may be recycled in the case of narrow processing, the increase may be related to the number of T-die extrusion, and at the same time Because it can be recycled, the purpose of the present invention is to solve the conventional problems related to the aforementioned adjustment of the film width adjustment: The σ of the film is to strengthen the film. Yield ratio is thin: == When the system is narrow, the f film manufacturing method and-film system = method, ;; == In the case where the number of films is the maximum number, it can also be adjusted.
