でのスリップに起因する蛇行や巻姿不良を防止すること
が知られている。When winding a web, especially a thin film, meandering and poor winding may occur due to slippage between the films or between the film and the roll. Conventionally, in order to prevent these problems, in the film manufacturing stage, as shown in Fig. 4, embossing E processing is performed on both edges (edges) of the film 1 to increase the film thickness by about 5 to 15 μm. This is known to prevent meandering and poor winding caused by slips between films and film transport rolls.

近年のフィルムｌの幅広化に伴って顕著に現れている。However, if the continuous film having embossed portions is long and wide and is to be wound at high speed, it is preferable to wind it around the core with high tension in order to prevent air from being entrained during winding. However, if you wind it while applying high tension, 1.
The part of the film corresponding to the position of the step D (see FIG. 5) between the leading edge of the film and the winding core 3 is transferred and deformed for more than ten meters after the second spring. This trend is
This has become more noticeable as the width of films has increased in recent years.

の巻取方法を開発することにある。Therefore, an object of the present invention is to prevent meandering and poor winding by using a film that has embossed portions in advance, as well as to prevent the base level difference at the beginning of winding that occurs when using a film that has embossed portions. The purpose of this invention is to develop a film winding method that prevents end transfer and winding misalignment.

できる。The above problem is a method for winding up a continuous web having embossed portions on both sides in the width direction while pressing a touch roll toward the winding core, wherein the contact portion of the touch roll substantially covers the embossed portions on both sides in the width direction. This can be solved by being located only in Further, there is provided a method for winding up a continuous web having embossed portions on both sides in the width direction and in the middle in the width direction while pressing a touch roll toward the winding core, wherein the contact portion of the touch roll portion is substantially only in the embossed portion. This can be solved by being located.
本発明においては、第１図および第６図のように、フィ
ルム１のエンボス部Ｅのみにタッチロール２の接触部２
ａを接触させながら、巻取を行うものである。In the present invention, as shown in FIGS. 1 and 6, the contact portion 2 of the touch roll 2 is attached only to the embossed portion E of the film 1.
Winding is performed while contacting with a.

しないので、すり傷等品質面への悪影響が全く無い。As long as the embossed portion continues to be pressed by the touch roll, the frictional force at the embossed portion is large, and even if winding is performed with low tension, the winding misalignment will be eliminated. Also, since the pressing force of the touch roll does not act on anything other than the embossed part,
Furthermore, since winding can be performed with low tension, it is possible to prevent end transfer due to a step difference in the film at the beginning of winding. In addition, since the touch roll does not come into contact with the enhos parts, which are product parts, there is no adverse effect on quality such as scratches.
以下本発明を図面に示す具体例によってさらに詳説する
。The present invention will be explained in more detail below with reference to specific examples shown in the drawings.

つ、巻き取る。In the present invention, a touch roll winding method is adopted in order to prevent end transfer and winding misalignment due to a step difference in the film at the beginning of winding at the time of winding. That is, the second
As shown in the figure, while the core 3, which is supported by a bearing 5, is rotated by a drive device (not shown), a film l is placed on the core 3.
In the process of winding up the touch roll 2, the cylinder 4
While pressing the film I against the winding core 3 side, wind it up.
本発明においては、特に、第１図および第６図で示すよ
うに、タッチロール２を、その両端の突出環状部分２ａ
、２ａを介して、フィルム１のエンボス部Ｅ、Ｅのみを
押し当てながら巻取りを行う構成としている。In the present invention, in particular, as shown in FIGS. 1 and 6, the touch roll 2 has protruding annular portions 2a at both ends
, 2a, the winding is performed while only the embossed portions E, E of the film 1 are pressed against each other.

差による端末転写を防止することかできる。According to this embodiment, since the film 1 having the embossed portions E, E is used in advance, there is no meandering or poor winding appearance, and the touch roll 2 is always applied to the embossed portions E, E from the start to the end of winding. Since it is pressed, there will be no winding misalignment even when winding is performed with low tension. Further, since winding can be performed with low tension and the pressing force acts only on the embossed portion, it is possible to prevent end transfer due to a step difference in the film at the beginning of winding.
ところで、巻取過程において、タッチロール２の表面は

硬質プラスチック、ハードクロム、メツキされたアルミ
等の硬質な材質を用いるのが好ましい。By the way, during the winding process, the surface of the touch roll 2 is always in contact with the embossed part E and is easily worn.
It is preferable to use a hard material such as hard plastic, hard chrome, or plated aluminum.

That is,
Protruding annular portions 2A, 2a... are formed at both ends and the middle of one touch roll 2, and each protruding annular portion 2A,

Further, in addition to being integrated with the touch roll, the protruding annular portion may be a separate body whose position can be varied in the length direction (width direction of the film) in order to accommodate changes in the width of the film.

を押し付けながら巻き取った例である。At this time, while changing the initial winding tension and the pressing form by the touch roll, the film end transfer distance and the winding state were measured and observed, and the results shown in Table 1 were obtained. In Example 1, the one shown in FIG. 1 was used, and the protruding annular portion was made of hard plastic. Comparative Examples 1 and 2 are examples in which the film was wound up while pressing a touch roll between the embossed portions.

った。As shown in Table 1, in Comparative Example 1, 50kgf
Since the film was wound with a high tension of /width, no winding deviation was observed, but transfer of the film end over a period of 16 m from the start of winding was confirmed. On the other hand, in Comparative Example 2, 25 kg
Since the film was wound with a low tension of f/width, the transfer of the film end was very small at 4m from the start of winding, but at 20v
A misalignment in the winding of s was confirmed. However, in Example 1, in which winding was carried out using a touch roll that pressed only the embossed part of the film with a low tension of 25 kgf/width, the film end transfer was only slightly suppressed to 4 m from the start of winding. Moreover, no misalignment of the winding was observed.

無いと考えられた。By the way, film end transfer for 3 to 4 turns from the start of winding inevitably remains due to the accuracy of the core remaining detector. Therefore, since the value of 4 m, which is the base end transfer distance detected after winding is completed, corresponds to 4 to 5 turns from the start of winding, it was considered that there was virtually no film loss due to end transfer.

It is possible to prevent end transfer based on , and also to prevent winding misalignment.
