In the figure, 7 is a payoff reel, 8 is a group of equipment on the entrance side including welders, 9 and 10 are bridles on the entrance and exit sides, 11 is a traveling direction changing device shown in FIG. 2, 12 is a rolling mill, and 13 is a tension reel. Is. The strip material 3 is, for example, a strip steel plate after annealing. The coil-shaped steel strip 3 supplied from the pay-off reel 7 passes through the entrance side bridle 9 and passes through the direction changing device 11.
Then, the course thereof is changed to, for example, a right angle direction, is sent to the rolling mill 12 through the exit side bridle 10, is rolled to a required plate thickness there, and is then wound by the tension reel 13.

より多角柱状に折れ曲がる。<Problems to be solved by the invention> By the way, in the traveling direction changing device 11, the strip steel plate 3 is
The guide rollers 6 travel and are guided by contact with a large number of guide rollers 6 arranged on the virtual conical generatrix 14, but the number of guide rollers 6 is limited due to the structure of the device.
If the number of the busbars 14 that can be taken is not sufficient for the specifications (plate thickness, hardness, etc.) of the treated steel plate 3, the strip steel plate 3 may bend in a polygonal pyramid shape due to the magnitude of the tension, or a guide roller due to high tension. 6 and the strip steel plate 3 may cause an indentation of a roll mark on the strip steel plate 3 due to an excessive surface pressure to deteriorate the quality of the product plate material. In particular, this tendency is large when processing a soft thin plate material after annealing, and it is extremely possible to prevent the occurrence of waist breaks and roll indentations if the sheet is passed with the tension (about 1 kg / mm 2 ) or more applied. It will be difficult. Such a problem also occurs when the device shown in FIG. 1 is used as the traveling direction changing device. However, in this case, the strip steel plate 3 is bent by the guide roller 2 into a polygonal column shape.

センタリングが悪くなる等の難点が生じる。As a means to prevent the above problems, the bridle on the entrance side and the exit side
It is conceivable to control 9,10 to lower the tension, but in the example line, the bridle 9,10 is used for the incoming equipment group 8
Also, it is necessary to satisfy the operating tension condition of the rolling mill 12,
It is technically difficult to satisfy both conditions at the same time. Further, in order to satisfy the tension condition in the traveling direction changing device 11 as well, the bridle becomes large, and even if the bridles 9 and 10 can control the tension in the traveling direction changing device 11 to be low. If the low-strength strip steel plate portion is long in the line, it approaches a tensionless state and becomes a catenary state, which easily causes interference with the strip passing device. In addition, the meandering control of the strip steel plate 3 is also performed. There are many technical problems such as difficulty. Furthermore, the high tension as described above (for example,
When operating at about 1 kg / mm 2 or more), the traveling direction changing device 1
The wear of the guide roller 6 in 1 increases, and as a result,
There is a problem that the stripping property of the strip steel plate 3 in the traveling direction changing device 11, that is, the centering is deteriorated.

Since the tension can be arbitrarily set only in consideration of the strip passing property of the strip, it is possible to completely prevent the bending of the strip in the conventional device and the flaw of the guide roller being pushed into the strip due to high tension, and the guide roller can be completely prevented. It is possible to significantly reduce the wear of the product, prevent the quality of plate products from decreasing,
In addition, maintenance costs can be reduced. Furthermore, even thin plate materials and soft plate materials such as annealed materials, which have hitherto been particularly problematic in processing, can be easily threaded without any problems, and productivity can be improved. Incidentally, JP-A-56-16
The 1248 gazette discloses a technique of providing pinch rolls on the input side and the output side of the guide roller, but these pinch rolls simply press the plate in order to prevent the plate from rising and lateral deviation. That is, tension control is not performed as in the present invention.
