    Patent number: 6257520
    Abstract: A tension determining apparatus that is arranged above cylindrical air chambers determines tensions at both edges of a web before the web enters helical routes of the cylindrical air chambers. Middle direction changing air chambers among three direction changing air chambers arranged in a row are inclined by a predetermined angle according to the difference between the tensions at both edges of the web. Therefore, a snaking and a bias of the web are reduced, and the web can run stably.
