転換に適したもの等である。Various methods have been considered as means for improving conveyance stability, for example, Japanese Utility Model Publication No. 57-11971 and Japanese Patent Laid-Open No. Sho 71-11971.
Various side guides (collars) have been proposed as measures against meandering in 63-176435 and JP-A-1-110464. These are those with springs, those that can accommodate changes in plate width, those that are suitable for direction change, and the like.

ということも起こる。However, there is a limit to the meandering prevention by the side guides alone, and when the meandering amount is large, the edge of the web is damaged, and further, the web surface is scratched by getting over the side guides. Web breaks also occur.

転換体の姿勢を制御する方法等がある。A method has also been proposed in which the meandering is corrected by tilting the diversion gas blowing box. For example, JP-B-61-2676, JP-A-62-157165, and JP-B-62-18566.
In No. 6, the arc-shaped guide surface can be tilted, and the inside of the guide surface is divided so that the blowout pressure can be changed in the width direction. There is a method of controlling.

にもなる。However, if the tilting method alone is used, it is 3-4.
In order to control fine meandering in the order of cm, it is necessary to tilt the direction-changing gas outlet box with high accuracy and at a high speed. To achieve this, a very high level of maintenance is always required. In addition, the web moves behind the tilt of the gas blowing box for direction change, which makes control very difficult. It becomes very expensive. As a result, the total maintenance load is increased, which is one of the causes of obstacles that increase the equipment mobility.

る。In the present invention, the direction-changing gas blow-out box can be tilted to accommodate a large amount of meandering, and fine meandering can be controlled by the brim, so that stable carrying property can be obtained. Further, when the web width is constant, it is preferable that the brim is on both sides. When the width of the web is changed, it can be easily dealt with by providing only one side of the brim. By the tilting mechanism, the entire traveling position of the web can be moved to the direction of the collar on one side to some extent, and further, the collar can suppress the meandering with a quick cycle. Moreover,
If the meandering detection sensor is installed on the side guide side, it is possible to easily cope with different widths without changing the installation position and changing the setting of the meandering control system. Especially when the length of the non-contact part exceeds 40 m, many position sensors, collars,
A position correction mechanism is required, and by combining such a tilting mechanism and one side collar, it is possible to greatly reduce initial costs, running costs, and maintenance.
【0011】さらに本装置を乾燥装置として用いてもよ

Further, when only the tilting device is used, when only the brim is provided on both sides, and when the tilting device and the brim of the present invention shown in FIG. It strongly hits the brim and some scratches were generated on the edge. Further, even in the case of only the tilting device, the meandering tends to be hunting and the conveyance is unstable. On the other hand, when both of the present inventions were used together, the transportability was good and stable transport was possible.
