。第３図は方向変換装置にこの側板を用いた例である。Although JP-A-63-176435 does not specify a direction changing device, it is a strip floating device that conveys the strip in a non-contact manner. This device is characterized in that a substantially upright side plate is installed on the side of the strip movement line. FIG. 3 shows an example in which this side plate is used in a direction changing device.

According to No. 35, the strip 1 is meandering, and as shown in Fig. 3 (B
), for example, if the gap 12 between the strip 1 and the side plate 11 becomes small, the fluid in the air suction 14 will flow through the small gap 12.
As shown in FIG. 3(C), the internal pressure 13 of the fluid cushion near 11 is smaller than the internal pressure 13 of the fluid cushion 11' as shown in FIG. 3(C). ', the strip is tilted and moved in the direction of arrow 15 to correct the position of the strip.

When the strip 1 is tilted, as shown in FIG. 3(C), the strip 1 comes into contact with the side plate 11, making it difficult for the strip to run, or the strip 1 and the side plate 11 come into contact, causing surface flaws on the strip.

Reference numeral 2 denotes a fluid pressure chamber into which fluid is pressurized, for example, from arrow 4. The fluid pressure chamber 2 has a semi-cylindrical convex upper surface. In the present invention, the semi-cylindrical shape refers to a semicylindrical shape that is close to a cylinder, and may be a geometric semi-cylindrical shape as shown in Fig. 1, or may be an ellipse or a shape with a deformed cylindrical arc surface. This is often referred to as a general term.

走行させる。In the present invention, edge nozzles 6 and 6' are further provided on the convex surface. The edge nozzles 6 and 6' float the strip 1 and prevent the strip 1 from moving in the direction of the arrow 7 and meandering. The edge nozzles 6 and 6' are provided as a pair on the top of a semi-cylindrical convex surface along the running path along which both ends 1-1 and 1-1' of the width of the strip plate 1 run, and their shape is like a V-shaped strip. The bottoms 6-1 and 6'-1 are formed facing outward as indicated by arrows 8 and 8,' in FIG. In the present invention, the strip plate 1 is run partially covering the V-shaped slits 6 and 6'.

力を受けて矢印８方向に移動する。In the apparatus of the present invention, when the strip 1 moves in the direction of the arrow 7 in FIG. Edge nozzle 6
It covers most of the edge nozzle 6' and is located away from most of the edge nozzle 6'. In Fig. 2 (B), on the 1-1 side of the strip l,
Since the strip 1 covers most of the edge nozzle 6, most of the fluid from the edge nozzle 6 is ejected towards the strip 1, increasing the pressure inside the edge nozzle 6 1-1.
The side edges are lifted. On the other hand, on the 1-1'' side of the strip, since the strip 1 is detached from the edge nozzle 6', the pressure on the inside 16' of the edge nozzle 6' does not increase due to the fluid jetted from the edge nozzle 6' to the strip 1. The amount of fluid decreases and there is no rise on the 1-1' side.Therefore, the strip 1 is tilted as shown in FIG. Moving.

る。従って帯板ｌは常に、流体圧力室２の中央を自然に
走行することとなり、帯板１の蛇行走行を防止する。As mentioned above, for example, when the strip 1 starts meandering and deviates in the direction of the arrow 7, the edge nozzles 6 and 6' tilt the strip 1 and move in the direction of the arrow 8 as shown in FIG. 2(B). let Therefore, the strip plate 1 always runs naturally in the center of the fluid pressure chamber 2, thereby preventing the strip plate 1 from meandering.

ち上げる方向に噴出するため、帯板の端部１−１は効率
よく持ち上げられる。In the present invention, the edge nozzle 6 has a V at the top of the fluid pressure chamber.
It is formed with the bottom facing outward. Therefore, when the strip 1 shifts in the direction of the arrow 7, the end 1-1 of the strip 1 approaches the bottom 6-1 of the edge nozzle 6, as shown in FIG. 2(C). 1, the fluid is ejected from the edge nozzle 6 in a direction that vertically lifts the strip 1, as shown by the arrow 9, so that the end 1-1 of the strip is efficiently lifted.
一方帯板の他の端部１−１′では、帯板１が矢印７方向

端部１−１′が持ち上げられることがない。On the other hand, at the other end 1-1' of the strip, when the strip 1 is displaced in the direction of the arrow 7, the end 1-1' of the strip 1 is connected to the edge nozzle 6'.
However, as shown in FIG. ,
Since the jet is ejected so as to swell the strip 1 laterally, the end portion 1-1' of the strip is not lifted up.

際、第２図（Ｂ）で示した如く帯板１は効率よく傾斜し
て、帯板１を迅速に矢印８方向に移動させて、帯板ｌの
蛇行走行を迅速に矯正し防止する。As described above, in the present invention, the edge nozzles 6 and 6' are formed in a V shape with the bottom facing outward at the top of the convex surface of the fluid pressure chamber. When this occurs, the strip plate 1 is efficiently tilted as shown in FIG. 2(B), and the strip plate 1 is quickly moved in the direction of arrow 8, thereby quickly correcting and preventing the meandering movement of the strip plate l. .

蛇行を自然に矯正する。In the present invention, the strip plate 1 is inclined when the meandering starts. However, in the present invention, unlike the above-mentioned Japanese Patent Application Laid-Open No. 63-176435, since the direction changing device is not provided with a side plate, the strip plate 1 is tilted.
Even if the strip is tilted, it does not come into contact with the side plates, etc., and the running of the strip is always kept smooth.Also, as already mentioned, the present invention is different from JP-A-60-138019 in that the direction of the bottom is On the contrary, since the strip plate 1 does not cover the entire edge nozzle, the meandering of the strip plate 1 is naturally corrected.
