As an example of the arrangement position of the negative pressure roll 1, in FIG. 12A, the negative pressure roll 1 is arranged between the separators 23 and 23 that provide a space between the metal strips.

- the metal strip 13 is wound up by the recoiler 24.
- the metal strip 13 that has passed through the separator 23 comes into contact with the multiple nonwoven fabric laminated outer layer 5 of the negative pressure roll 1 from below. At this time, the negative pressure roll 1 rotates in such a manner that it is frictionally engaged at the contact surface between the multiple nonwoven fabric laminated outer layer 5 and the metal strip 13 and pulled by the frictional force.

- the magnitude of the negative pressure can be adjusted by the negative pressure adjusting valve 11.
- the surface side of the metal strip 13 in contact with the negative pressure roll 1 receives a pressure from atmospheric pressure in proportion to the negative pressure generated inside the negative pressure roll 1. Further, the braking device 6 provided on the negative pressure roll 1 can apply a braking force to the rotation. As a result, a winding tension acting in the direction opposite to the direction pulled by the recoiler 24 is applied to the metal strip 13.
- This winding tension applies a tension when the metal strip 13 is wound around the recoiler 24, so that it can be wound up neatly. Moreover, since the nonwoven fabric 20 of the multiple nonwoven fabric laminated outer layer 5 in contact with the metal strip 13 has moderate elasticity, even if a frictional force is generated, the contact surface with the metal strip 13 is hardly damaged. ing.
- the metal strip 13 that has passed through the negative pressure roll 1 is angled by the deflector roll 26 and wound by the recoiler 24, whereby the coil-shaped material of the metal strip 13 is completed.
- the negative pressure roll 1 is used in combination with the belt-type tension device 25 for a thick metal strip that requires a large winding tension. You can also. Alternatively, for materials where slight scratches on the surface are not a problem, they are arranged on the rolls (102 and 103) in FIG. Can also be given.
- the negative pressure roll 1 composed of a low air-permeable surface material does not inhale excess air, so the internal negative pressure is kept high. Even if there is a gap, a sufficient winding tension can be applied.
- a wide sheet-like material formed of paper, resin, or the like can be reliably held and conveyed by being attracted to the negative pressure roll 1.
- a sheet-like material such as paper does not need to be adsorbed with a large negative pressure unlike a metal strip, and can be used with a negative pressure reduced by the negative pressure adjusting valve 11.
- the negative pressure roll 1 composed of a low-breathing surface layer material does not inhale excess air, so there is no need for a partition plate for adjusting the negative pressure area in the roll longitudinal direction even if the material width of the sheet material changes. Therefore, a sufficient gripping force can be exhibited with a simple configuration.

- the ultrathin plate is adsorbed by the negative pressure of the negative pressure roll 1, slip does not occur between the negative pressure roll and the ultrathin plate, and sufficient winding tension can be applied.
- the conventional multi-belt belt type winding tension applying device when tension is applied to an ultrathin plate, a mark due to the belt edge adheres to the strip and a slip is generated between the strip and the winding. The take-up tension could not be applied.
- the conventional tension pad method has a problem that scratches adhere to the band plate.
- the winding tension can be increased by increasing the roll diameter of the negative pressure roll 1. That is, a winding tension can be sufficiently applied even to a metal strip having a large plate thickness, and the application range can be expanded.
- the negative pressure conduction portion 10 is formed in a region of approximately 90 degrees on the circumference of the negative pressure roll 1 as shown in FIG.

- the negative pressure conducting portion 10 can be formed in a region of about 180 degrees on the circumference of the negative pressure roll 1. In this case, since the metal strip 13 rising from below is in contact with the region of about 180 degrees on the negative pressure roll 1, a larger negative pressure can be applied. That is, it is possible to apply a larger winding tension or gripping force. Moreover, if the negative pressure conducting part 10 is prepared as a replacement part having an arbitrary angle, the circumferential negative pressure region can be arbitrarily adjusted.
- the suction roll device to which the present invention is applied can cope with problems peculiar to the multi-strip metal strip. This problem is a problem of a speed difference generated between the metal strips.
- the uncut metal plate coil provided to the slitter line has plate thickness deviations different in thickness in the plate width direction even if the plate is coplanar due to a problem during processing. This thickness deviation leads to an outer diameter difference of the winding coil when the metal strip is wound around the recoiler after being cut into multiple strips.
- the metal strip of the coil having a large outer diameter will be wound faster, and the metal strips due to the outer diameter difference on the negative pressure roll will be wound. A minute speed difference occurs. At this time, the negative pressure roll is drawn and rotated by the metal strip having a large outer diameter, and the winding roll of the metal strip having the small outer diameter is bent and cannot be wound firmly.
- the braking force is increased by the braking device 6 and the rotational speed of the negative pressure roll 1 is suppressed, so that the metal strip having a high winding speed is slightly slipped on the negative pressure roll, and the metal that has been bent is generated. Winding tension can also be applied to the strip.
- the metal strip having a large outer diameter of the winding coil can be easily slipped on the negative pressure roll without increasing the braking force. While slipping a metal strip having a high winding speed, an appropriate winding tension can be applied to a strip having a low winding speed, and a uniform winding tension can be applied to all the metal strips.
- the suction roll device to which the present invention is applied can cope with the problem of the speed difference generated between the multiple strips of metal strips, and can apply a uniform winding tension without scratching. It has become.
- the suction roll device of the present invention can provide a sufficient winding tension by increasing the negative pressure inside the device without damaging the metal strip.
- the winding tension can be applied to a strip having a small thickness or a strip having a small width. Further, it is possible to grip and convey a sheet-like material formed of paper, resin, or the like. Furthermore, uniform winding tension can be imparted to a multi-strand metal strip.
- the suction roll device can sufficiently grasp and convey or brake various long materials without damaging them, and can reliably take up.
