Description
このように、安定した巻取りテンションを得ることができるため、巻き取った状態の幅方向のずれ量を小さくすることができ、例えば3.0mmであったずれ量を0.5〜1.0mm程度にまで縮小することができる。その結果、巻き取った状態の外観が良好となり、外観上のNGを減少させることができる。また、厚みが50〜300μmの比較的厚い細幅のウエブ16aの巻き取りにも好適となる。 In this way, since a stable winding tension can be obtained, the amount of deviation in the width direction in the wound state can be reduced, and the amount of deviation, which was , for example, 3.0 mm, can be reduced to 0.5 to 1. It can be reduced to about 0 mm. As a result, the appearance in the wound state becomes good, and NG in appearance can be reduced. It is also suitable for winding a relatively thick and narrow web 16a having a thickness of 50 to 300 μm.
ところで、ウエブ16aを巻き取る上で理想的なテンションカーブが存在する。通常、巻取り装置100によってウエブ16aを巻き取る場合、その巻き取りに伴ってホルダ106へのウエブ16aの巻き径が大きくなっていき、その分、ホルダ106の回転数が減少する。それに伴って、図8に示すように、テンションカーブ(曲線a)となり、理想的なテンションカーブ(曲線b)から外れる場合がある。そこで、通常、一定としている駆動軸104の回転数を20〜30%ほど上げることにより、テンションカーブ(曲線a)を理想的なテンションカーブ(曲線b)に近づけることができる。 By the way, there is an ideal tension curve for winding the web 16a. Normally, when the web 16a is wound by the winding device 100, the winding diameter of the web 16a around the holder 106 increases with the winding, and the rotation speed of the holder 106 decreases by that amount. Along with this, as shown in FIG. 8, it may deviate from the tension curve (curve a), and the ideal tension curve (curve b). Therefore, the tension curve (curve a) can be brought closer to the ideal tension curve (curve b) by increasing the rotation speed of the drive shaft 104, which is normally constant, by about 20 to 30%.
