がある。2. Description of the Related Art In recent years, for the purpose of improving productivity and yield, a continuous annealing line is followed by a temper rolling line and a conditioning line. At that time, even if it is an existing continuous annealing line and there is no space linearly continuous to this line on the exit side, or even if it is a new installation, it is a long line on a straight line in terms of layout. There is a demand for changing the traveling direction of the steel strip (guiding in a curved direction by a predetermined angle) on the exit side of the continuous annealing line because it may be unfavorable or the construction cost may be high.

の周面に鋼帯が接触することもある。However, in this apparatus, since the steel strip is guided while being spirally bent, the steel strip tends to have a shape with a small bending strain due to rigidity, particularly in the case of a steel strip having a large plate thickness. As a result of being guided in a twisted state,
There may be a difference in the flying height in the plate width direction, and the steel strip may come into contact with the peripheral surface of the cylindrical body on the side where the flying height is small.

The angle is not limited to this as long as it is an acute angle, and the smaller the change angle α is, the smaller the degree of twisting is, which is preferable. However, depending on the movement angle between the two lines, the number of floaters used may be increased or necessary for direction change. Since the space to be formed becomes large, it is economically set to, for example, 30 ° or more.

Therefore, the change angle α by one floater is equal to the change angle by one guide surface 2, but when the steel strip is wound around the cylindrical body 1 forming the floater a plurality of times, a number corresponding to the number of times of winding around the cylindrical body 1 is used. Of the guide surfaces 2a to 2c are formed continuously, as shown in FIG.
The change angles α 1 to α 3 in 2c are set to acute angles.

For example, it may be a semi-cylindrical shape or a cylindrical body having a cross section in which an arc and a polygon are connected.
