けたり、エンぎスの幅を広くしたり凹凸を高くし、更に
はエンボスを両面につける等により対処している。For example, in the manufacturing process of photographic film, a method of winding a flexible film-like base around a core is to apply an emulsion to a formed film base and send it to a drying section, thereby drying the photographic film base. It may be wound onto a core. In this winding process, as the film length of the photographic film becomes longer and the winding speed increases, winding misalignment tends to occur. In order to prevent this winding misalignment, the winding tension should be increased to the extent that the photographic film can withstand the pressure, or the width of the embossment should be made wider, such as by providing band-shaped embossments on both ends of the film base. This is countered by increasing the height of the irregularities and adding embossing to both sides.
しかし巻取張力を高める方法は、巻芯端末や端末貼り付

リや巻き取り時のスレ傷故障が発生しやすい等の問題が
ある。However, in the method of increasing the winding tension, there is a lot of loss at the end of the winding core or at the end of the tape due to tape transfer. Further, there are problems such as fogging due to pressure and damage caused by scratches during winding.

果がなくなる等の不具合がある。On the other hand, the method based on the Enzes effect uses cellulose triacetate (TAO
) In the case of pace, the emboss marking depth tends to be uneven,
To compensate for this, winding with high tension will lengthen both sides of the pace and eliminate the embedding effect. Furthermore, when multiple layers of emulsion are applied to the film surface, there are problems such as the film thickness becomes higher than that of Endes, and the effect is lost.

ている。The present invention has been made in view of the above circumstances, and by winding the core side of the flexible film base tightly, the problem of the problem that occurs due to the lengthening of the original volume and the speeding up of the winding speed is reduced. It is possible to prevent winding misalignment, and also prevent the occurrence of winding misalignment of the original winding that has no embossed effect, and enables low tension winding, which effectively eliminates pressure fog and tape transfer loss at the end and sticking of the core. It is an object of the present invention to provide a method for high-speed winding of a flexible film-like paste, which can prevent such problems and obtain a good winding condition.

る。In this way, according to the present invention, by raising both ends of the core and winding it up, the ends of the flexible film-like paste can be tightly and securely wound, which can cause problems caused by winding up due to longer lengths and higher speeds. It is possible to prevent the winding from slipping easily. Especially in the case of photosensitive materials such as photographic film bases,
There is no problem since both ends are discarded. At the same time, by winding both ends of the core high, the inner side of the original winding can be wound loosely, so that there is no loss due to transfer of the core, such as pace ends and tape attachment parts, and a good winding condition can be obtained.
