４−５５２５４号公報に記載されているものがある。2. Description of the Related Art When a plurality of treatments are continuously performed on a steel strip or the like, the traveling direction of the steel strip may be changed between processing apparatuses due to a layout problem of the entire equipment. As an example of a device for changing the traveling direction of a strip material, there is a device described in Japanese Patent Application Laid-Open No. 4-55254.

路として鋼帯Ｓを浮上状態で案内する。This device, as shown in FIGS. 5 and 6,
A spiral belt-shaped portion 2a is provided on the semicircular peripheral surface of the cylindrical floater 1a so that the steel belt surface is opposed to the spiral belt-shaped floater 1a, and a number of gas ejection ports 22, 22a penetrate the spiral belt-shaped portion 2a. The gas introduced into the floater 1a is jetted from the gas jet port 22 toward the steel strip surface, and the steel strip S is guided in a floating state using the spiral strip 2a as a traveling path.

A side plate 5 is provided upright. This side plate 5
It is formed at one end of a cylindrical body 31 having an inside diameter that can be fitted to the cylindrical floater 1a, and this cylindrical body 31 serves as a cover for closing the gas outlet 22a of the spiral band-shaped portion serving as a non-progressive passage.

【発明が解決しようとする課題】しかしながら、前述の
サイドプレートとカバーを有する帯状材進行方向変更装
置には、以下のような問題点がある。However, the device for changing the traveling direction of a strip having the above-mentioned side plate and cover has the following problems.
【０００７】図７は鋼帯にかかる張力と浮上量との関係

合（曲線ａ）とそれほど浮上量に差はないことが分か
る。FIG. 7 is a graph showing the relationship between the tension applied to the steel strip and the flying height. Curve a shows the case where there is no side plate, and curve b shows the distance between the side plate 5 and the widthwise end of the steel strip S. When d is 30 mm, the curve c has a distance d of 80 mm.
Is the case. The lower the tension, the higher the flying height of the steel strip. Also, as compared with the case without the side plate (curve a), if the distance d is 30 mm (curve b), the flying height increasing effect is higher, but the distance d is higher. It can be seen that the effect of increasing the flying height is low when it is as large as 80 mm (curve c), and the flying height is not so different from that without the side plate (curve a).
【０００８】一方、鋼帯を通板すると蛇行が発生する

端部がサイドプレートに接触して、鋼帯に疵が発生する
恐れがある。On the other hand, meandering occurs when the steel strip is passed through, and the meandering amount increases as the passing speed increases.
For example, FIG. 8 is a graph showing the meandering amount distribution when the passing speed is 400 m / m. From the graph, if the distance d is not more than 80 mm, the meandering of the steel strip causes the width direction end of the steel strip to have a side surface. There is a possibility that the steel strip may be damaged by contact with the plate.
【０００９】すなわち、鋼帯の通板速度が高くなるほ
ど、サイドプレートによる接触疵を防止するために距離
ｄを大きくしなければならないが、これによって逆に鋼
帯の浮上量増大効果は低下してしまい、サイドプレート
の無い場合とほとんど差はなくなってしまうのである。That is, as the passing speed of the steel strip increases, the distance d must be increased in order to prevent contact flaws caused by the side plate. However, on the contrary, the effect of increasing the flying height of the steel strip decreases. In other words, there is almost no difference from the case without the side plate.

される。Further, since the cover (cylindrical body) 31 is arranged outside the cylindrical floater 1a, when the gas in the cylindrical floater is jetted from the gas jet port toward the steel strip surface, as shown in FIG. , Spiral band 2a of cylindrical floater 1a and cover 3
The gas enters the gap with the gas outlet 1 from the gas ejection port 22a and floats the cover 31, so that the gas is wastefully exhausted from the gap.

In the above, the flaw is not generated in the steel strip at the time of high-speed passing, and the invalid flow rate of the gas (the flow rate of the introduced gas that is discharged without being used for floating the steel strip)
It is an object of the present invention to reduce the amount.

する。In order to solve the above-mentioned problems, according to the present invention, a guide surface which opposes a surface of a band-shaped material is provided on a peripheral surface of a cylindrical body with a predetermined width in an axial direction. A large number of gas ejection ports for ejecting gas from the cylinder toward the surface of the band-shaped material are provided, and the gas ejected from this gas ejection port,
In the band-moving direction changing device for changing the moving direction by guiding the band in a direction intersecting with the axial direction of the cylindrical body in a floating state from the guide surface, the gas ejection ports at both ends in the width direction of the guide surface are provided.

状材の幅に応じて進行通路幅が変更できる。By covering the gas outlets at both ends in the width direction of the guide surface with the cover, the gas discharge width (progress passage width) in the width direction of the guide surface becomes smaller than the width of the guide surface. Accordingly, unnecessary ejection of gas is prevented. Here, the cover is not a circumferentially continuous tubular, I plate der, it is fitted in the semicircular surface of the cylindrical body

These spirals are provided as a width-direction outline 21 with a predetermined width L A (dimension sufficiently larger than the width L S of the guided steel strip S) in the axial direction. Through holes (gas outlets) 22 are provided at equal intervals on the entire surface of the guide surface 2. Such a guide surface 2 is formed by, for example, forming a portion corresponding to a portion between two outlines 21 of the cylindrical body 1 with a punching metal.

A plate-like cover 3 formed in the same shape as the outline 21 is provided. As shown in FIG. 3, the cover 3 covers the through holes 22 at both ends in the width direction of the guide surface 2, and a gas ejection width (progress passage width) L
K is set to a width corresponding to the width L S of the steel strip S (smaller than the width L A of the guide surface 2).

る。Gas is introduced into the cylindrical body 1 at a predetermined pressure by a gas introducing device (not shown), and the introduced gas is passed through the through hole 22 from the inside of the cylindrical body 1 to form a steel strip S.
It is supposed to be squirted toward the surface. Because of the jet gas, the steel strip S is guided along the guide surface 2 from the cylindrical body 1 in a floating state and proceeds, so that the traveling direction is changed.

As a result, the cover 3 is moved along the traveling path width L
Since the through hole 22 outside the K can be reliably closed, unnecessary ejection of the gas to the outside of the traveling path is reliably prevented. As a result, the amount of gas introduced wastefully is reduced, so that a smaller blower can be used, which leads to cost reduction.
