搬送中に発生し易く、この蛇行を制御することが安定操
業には欠かせない。In the continuous processing line for the above-mentioned strips (hereinafter, the strip will be explained as an example), meandering of the copper strip tends to occur during transportation, mainly due to poor shape of the copper strip, and it is important to control this meandering stably. Indispensable for operations.

No. 4, No. 6105, and No. 6106 disclose methods using tires, disks, and jets, respectively, but the contact area with the steel strip is small, the copper strip is easy to slip, and the steel strip Depends on defective shape, etc.
Its control ability is still insufficient. On the other hand, if a centering function of the copper strip is added to the conveyor roll, that is, a crown is added to the conveyor roll,
Meandering can be stably corrected. However, since the meandering of the copper strip varies depending on the material, shape, size, processing conditions, etc. of the copper strip, it cannot be handled with a fixed crowned roll. Therefore, various proposals have been made regarding a conveyance roll that has a centering function that can cope with various meanderings by changing the crown of the conveyance roll.

In addition, the pressurization chamber is made up of a variable crown conveyor roll consisting of multiple chambers divided by partition walls and means for adjusting the pressure of the fluid filled in each chamber, and in particular, the pressurization chamber is supported at the center of the roll cylinder by a partition wall of a diaphragm. This is a variable crown type conveyor roll that is divided into an inner chamber that supports the roll body and an outer chamber that supports the roll body end.

。Here, the elastic cylindrical body is a cylindrical body made of a material that has both appropriate elasticity and rigidity.For example, if you want to increase the amount of change in roll crown, use rubber with steel cord (the same structure as a radial tire can be applied). On the other hand, when rigidity is required when the amount of roll crown is extremely small or when used in a high temperature atmosphere, it is advantageous to use a thin metal plate such as stainless steel (used within the elastic limit of metal).

The roll crown is made variable by changing the diameter of the roll cylinder in its axial direction. In particular, since the fluid pressure to each chamber constituting the pressurized chamber can be adjusted independently, for example, the diameter between the center of the roll cylinder and the end of the roll cylinder, or the diameter of each roll cylinder end can also be adjusted independently, making it possible to adjust the variable width of the roll crown. It can be expanded further.

さてこの発明に従うクラウン可変式搬送ロールの好適例
を、第１図に示す。(Example) Fig. 1 shows a preferred example of the variable crown conveying roll according to the present invention.
図中１は弾性円筒体よりなるロール胴で、このロール胴

ロール胴１に付加させ得る構成とした。On the other hand, inside the roll cylinder 1, a cylinder 4 in the form of a pressurizing chamber 3 is disposed coaxially with the roll cylinder 1 inside a cylindrical body that contacts the inner wall of the cylinder 1, and this pressurizing chamber 3 is connected to the partition wall 5. two compartments 6,
It is divided into 7. Furthermore, the cylinder 4 is provided with a large number of through holes 8 that open toward the roll cylinder 1 side, so that the pressure in the compartments 6 and 7 can be applied to the roll cylinder 1.

して帯板をＢ側に移動させ蛇行を修正する。If the above-mentioned conveyance roll is used, for example, if the strip plate 13 moves toward the A side as shown in Fig. 2, it is only necessary to correct the strip plate 13 by moving it to the B side, depending on the meandering amount and meandering speed of the strip plate. Based on this, the fluid pressure in the compartment 7 is increased, the roll crown is changed, the strip is moved to the B side, and the meandering is corrected.
