があった。However, since the carrying roll having the above structure exerts an unreasonable force on the belt-shaped material due to the resistance of the bearing, when it is used for a low tension material such as a resin film, breakage or cracks occur. There was a problem to do. On the other hand, it is possible to rotate the carrier roll by a driving device to reduce the resistance of the bearing and use it as a carrier roll of low tension material, but as the number of rolls increases, the speed of each roll becomes the same. However, there is a problem in that it requires a large amount of equipment and cost for the adjustment.

問題点があった。Further, in the case of a long conveying roll for conveying a wide material, there is a problem that the material cannot be stably conveyed due to a large bending. In order to prevent this, the method of increasing the thickness of the roll or changing the material of the roll to increase the strength of the roll is taken, but the weight of the transport roll increases and the resistance of the bearing increases. There was a problem.

In this way, a pressure difference is generated between the upper space 47 and the lower space 48 partitioned by the partition wall 49, so that the upper gap 56a facing the upper space 47 and the lower gap 56b facing the lower space 48 are static. There is a difference in pressure and the outer cylinder 5

To do this, adjust the butterfly valve 53 and
7 is increased, and a large amount of air is discharged from the through hole 36 communicating with the upper space 47 to increase the amount of air flowing into the upper space 47.
The static pressure of 6a should be increased. The upper portion 65 of the outer cylinder 55
If a strong pressure is constantly applied to the upper space 47, the area of the through hole 36 communicating with the upper space 47 may be increased to discharge a large amount of air into the upper gap 56a, and the static pressure in the upper gap 56a may be constantly kept high.

It is held in the gap for a long time, and a stable static pressure is secured in the gap. As a result, the outer cylinder is rotatably levitated and supported, so that there is almost no resistance when the outer cylinder rotates. Therefore, since an unreasonable force is not applied to the belt-shaped material supported and conveyed by the outer cylinder, it is possible to convey a low-tensile material such as a metal foil or a resin film. Further, since the outer cylinder is floated and supported by the static pressure of the fluid over its entire length, the outer cylinder does not bend. Thereby, the strip-shaped material is stably conveyed.
