PURPOSE: To pass a steel strip at a low flow rate of gas for floating with good stability by trisecting a floating supporting device to front and rear supporting devices and linear supporting device disposed therebetween before the direction of the traveling steel strip is changed in direction respectively 90°.
CONSTITUTION: The steel strip 1 travels from below and changes the direction downward by 180°. The steel strip 1 traveling from below is run horizontally by the 1/4 arc-shaped floating supporting device 2 assigned to make 90° turn. The steel strip 1 traveling horizontally is then supported from below by the linear floating supporting device 3. The steel strip 1 is successively turned 90° downward by the arc-shaped supporting device 2' similar to the rear device 2. The devices 2, 3, 2' have nozzles 4 facing inward to each other so as to intersect orthogonally with the traveling direction of the steel strip 1 and receive the pressure generated by the flow ejected from the nozzles 4 on pressure receiving surfaces 5.
