According to this Japanese Patent Laid-Open No. 176435/1988, the strip is floated and supported by a fluid cushion formed by the static pressure generated by the ejected fluid. When the strip meanders and the gap between the strip and the side plate becomes smaller, the fluid is less likely to escape from the small gap.Therefore, the pressure of the fluid cushion near the side plate where the gap between the strip and the side plate becomes smaller Becomes higher, and the strip tilts so that the end closer to the side plate becomes higher. Due to this inclination, a component force in the width direction is generated in the static pressure generated by the ejected fluid in a direction opposite to the meandering direction, and the position of the belt-like material is corrected.

The installation intervals of the following floaters for strips and the side plates are different from those of the present invention (width of strips + floating height of strips x 8).
The difference in action of each side plate will be described with respect to the larger floater for strips.

It is explanatory drawing of the effect | action of the side plates 3-1 and 3-2 when installed below. FIG. 4A is a cross-sectional view of the float 1 cut in the width direction of the strip 1 when the strip 1 is located at the center of the floater 2 and the pressure distribution of the fluid cushion applied to the strip 1 at that time.

安定する。FIG. 4 (B) is a cross-sectional view of the float 1 cut in the width direction of the strip 1 when the strip 1 meanders rightward by some external force, and a fluid cushion applied to the strip 1 at that time. Is the pressure distribution. In this case, even if the amount of meandering is small, the pressure of the fluid cushion near the side plate 3-1 closer to the meandering strip 1 immediately increases, and conversely, the pressure of the fluid cushion near the side plate 3-2 increases. The pressure drops. As a result, the left-right symmetry of the pressure distribution applied to the strip 1 is broken, a counterclockwise moment acts on the strip 1, and the strip 1 inclines so that it becomes higher as it approaches the side plate 3-1. The component of the static pressure in the width direction generated by the ejected fluid is generated in the direction opposite to the meandering direction, the position of the strip 1 is immediately corrected, and is stabilized in the center of the floater 2.

ることがない。In this case, the side plate 3 on the side where the strip 1 approaches
Since the distance between -1 and the end of the strip 1 is 4 times or more the flying height of the strip 1, the pressure of the fluid cushion near the side plate 3-1 does not change. Further, the distance between the side plate 3-2 on which the strip 1 is far away and the end of the strip 1 is also four times or more the flying height of the strip 1, so the pressure of the fluid cushion in the vicinity of the side plate 3-2. Does not change. Therefore, the center of pressure is fixed to the center of the floater 2, but the center of tension and gravity of the meandering strip 1 shifts to the left as the meandering, and a clockwise moment acts on the strip 1. As a result, the strip 1 is inclined so that it becomes lower as it approaches the side plate 3-1, and due to this inclination, the component component of the static pressure in the width direction generated by the ejected fluid is generated in the same direction as the meandering direction. The position of the strip 1 meanders further to the left and is not stabilized in the center of the floater 2.

It was done manually by visual inspection. Although not shown in the figure, instead of this method, a width detector (for example, an optical width meter) that detects the width of the strip 1 and emits the size of the width as an electric signal is used on the way of the travel route of the strip 1. In addition, it is provided between the unwinding part of the band and the floater 2. Further, a speedometer for detecting the conveying speed of the strip 1 and emitting it as an electric signal is provided.
Further, receiving the width information from the width detector and the speed information from the speedometer, the width change point of the strip 1 is set to the floater from the distance from the installation position of the width detector to the floater 2 and the speed information from the speedometer. The arrival timing is calculated, and the distance between the side plates 3-1 and 3-2 is set to (width of strip 1) or more and (width of strip 1 + flying height of strip 1) from the width information of the width detector. 8 × or less, the driving devices 4-1 and 4-2 are arranged at the timing when the width change point of the strip 1 reaches the floater.
A control device is provided for controlling the operation. Width detector,
The speed detector and the control device detect the width change of the strip 1 and the timing at which the width change point reaches the floater by the width detector and the speedometer in advance, and the control device drives the drive devices 4-1 and 4.
-2 may be automatically opened and closed according to the width of the strip 1 passing through the floater 2. The drive devices 4-1 and 4-2 used in the present invention may be ordinary mechanical devices (for example, an air cylinder, a hydraulic cylinder, a gear type actuator, etc.).

Went through. The belt floater 2 has a radius of 1200 mm,
It is a semi-cylindrical type with a width of 1400 mm, and on the arc surface of the floater 2, the installation distance W of the side plates is (width B of strip 1 + strip 1
The side plates are installed at an interval of 1100 mm so as to be at least the floating height h × 8) above and substantially perpendicular to the arc surface of the floater 2. In this case, as a result of measuring the amount of meandering, it was ± 42 mm, and the strip did not pass through the center of the floater 2.
