ーを形成しないために、すり疵や折れ疵が防止できる。FIG. 6(B) shows a device using a conventional fluid cushion, in which fluid is forced into a fluid surface 5 through a fluid inlet 6, and is jetted out from a spouting nozzle 7 onto a steel strip 1. Due to this ejection, the strip steel plate 1 floats up and travels in the direction of arrow 4. According to this method, the strip steel plate 1 runs without contact. In addition, since no catenary is formed, scratches and creases can be prevented.
しかし流体面５を並べるこの装置は設備が大規模となる
し、また多量の流体をノズル７から噴出させるために、
操業コストが高いという問題点がある。However, this device in which the fluid surfaces 5 are lined up requires large-scale equipment, and since a large amount of fluid is ejected from the nozzle 7,

している。第３図（Ｃ）、（Ｄ）は下反りとは逆の例で
、上反りの図を示している。First, we will discuss the reason why cracks occur in the strip steel plate 1 in a conventional steel sheet without a catenary control fluid pad, for example, as shown in FIG. 6(C). In a belt-shaped steel sheet manufacturing apparatus, for example, a belt-shaped steel sheet heat treatment furnace, a belt-shaped steel sheet whose shape has not been straightened is run. That is, shape correction of a strip steel plate is often performed after heat treatment or the like. For example, in FIG. 6(C), the traveling steel strip 1
is a strip steel plate whose shape is not straightened. According to the findings of the present inventors, the belt-shaped steel plate 1 whose shape is not straightened does not have a flat cross-sectional shape at a point S0 sufficiently in front of the entry pad.
It often runs with a warp in the width direction. Figure 3 (
A) and (B) are diagrams showing an example of the shape of the steel strip 1 running in the vicinity of 81 points, (A) is a side view of the steel strip 1 running, and (B) is a side view of the steel strip 1 as viewed from the arrow. FIG. The belt-shaped steel plate 1 has a center portion 1-2 in the width direction that is convex than both end portions 1-1, 1-1' in the width direction, and forms a downward curvature in the width direction as shown in FIG. 3(B). The vehicle is traveling in the four directions indicated by the arrow. FIGS. 3(C) and 3(D) are examples of upward curvature, which is the opposite of downward curvature.
形状を矯正していない帯状鋼板は、第３図に示すように
、大体どちらかに反っている。A belt-shaped steel plate whose shape has not been corrected is generally warped in one direction or the other, as shown in FIG.
第３図（Ｂ）、（Ｄ）のような断面形状をもった帯状物

従来の、カテナリー制御流体パッド（以下中間パッドと
略記する）１４がない場合、帯状物１は第４図（Ａ）で
示すように、曲り難いので、右下方向へ直進しようとす
る。A band-shaped object with a cross-sectional shape as shown in FIGS. 3(B) and (D) inevitably has a large bending rigidity, and a conventional catenary control fluid pad (hereinafter referred to as an intermediate pad) as shown in FIG. (abbreviated as ) 14, as shown in FIG. 4(A), the belt-shaped object 1 is difficult to turn and tends to move straight toward the lower right.
従って右のパッド１３へ帯状物を通板させようとする場
合、パッド１２とパッド１３の間のどこかで、急に板が
曲げられ、板の折れ発生の原因となる。Therefore, when trying to pass a strip to the right pad 13, the plate is suddenly bent somewhere between the pads 12 and 13, causing the plate to break.
第４図（Ｂ）のように、本発明の装置では中間パッド１
４の案内により、１−１． （１−３）のような、板の
反りも小さく抑制され、スムーズに定った位置で一定の
曲率で曲げられるので、帯状物１の折れは発生しない。As shown in FIG. 4(B), in the device of the present invention, the intermediate pad 1
According to the instructions in 4, 1-1. As shown in (1-3), the warp of the plate is suppressed to a small extent and the strip is smoothly bent at a fixed position with a constant curvature, so that the strip 1 does not break.

ガスが無駄に抜けることにより、流量が大きくなる等５
問題が多い。Furthermore, if there is no intermediate pad 14, as shown in FIG. 5(A), the pass line will fluctuate due to fluctuations in tension.
As shown in FIG. 5(B) and FIG. 5(C), the separation point of the strip and the pad fluctuates, and the floating becomes unstable.
The pads are likely to come into contact with each other, which can cause scratches, and gas can escape unnecessarily, increasing the flow rate, etc.
There are many problems.
即ち、第５図（Ｂ）は正常な圧力が形成されて浮上が安
定であるが、第５図（Ｃ）は剥離点に流体噴出ノズルが
ないので、圧力が低下したり流が乱れて浮上が不安定と
なる。In other words, in Figure 5 (B), normal pressure is formed and the levitation is stable, but in Figure 5 (C), there is no fluid jet nozzle at the separation point, so the pressure decreases or the flow is disturbed and the levitation is stable. becomes unstable.
当発明は、中間パッド１４を、張力が小さくなり従って
カテナリーが大きくなった第４図（Ｂ）のパスライン１
６よりさらに下の方に設ける事により、パスラインを安
定させ、帯状物１とバットの剥離点を一定に保つように
している。The present invention moves the intermediate pad 14 to the path line 1 of FIG. 4(B) where the tension is small and the catenary is large.
By providing it further below 6, the pass line is stabilized and the separation point between the strip 1 and the bat is kept constant.
よって、接触疵の発生もなく、流量も少なくて済む。こ
れらの作用のため、帯状鋼板】には、折れ疵の発生がな
く、さらにパスラインが安定するので、ガスの無駄もな
くなり、ガス量も少なくて良い。Therefore, contact flaws do not occur and the flow rate can be reduced. Because of these effects, the strip steel plate does not suffer from folding and the pass line is stabilized, so there is no waste of gas and the amount of gas can be reduced.
［実施例コ
本発明者等は、第７図に示すように焼鈍炉１５内に本発

中間パッド１４がない場合は、炉内カテナリ一部で折れ
疵が発生し、パスラインは不安定で、ガス量も変動し、
安定した操業が菫かしかった。If there is no intermediate pad 14, cracks will occur in a part of the catenary inside the furnace, the pass line will be unstable, and the gas amount will fluctuate.
The stable operation was disappointing.
中間パッド１４の使用により、製品の折れ疵がなく安定
