Abstract: An absorption apparatus 1 that is an example of a loop amount absorption apparatus of a slitter line to which the present invention is applied is disposed in a region of a loop pit 3 provided in the slitter line 2. The absorption apparatus 1 includes a negative pressure roll 9 that grips and conveys strips and an up-down moving device 10 that enables the negative pressure roll 9 to move up and down. By gripping and conveying the strips 14 by the negative pressure roll 9, two loops 15 of the strips are formed. The negative pressure roll 9 includes a rotating shaft 16, an inner cylinder 17, an intermediate cylinder 18, and a non-woven fabric laminated outer layer 19.

Abstract: The negative pressure roll 1 is provided with a rotating shaft 2, an internal cylinder 3, an intermediate cylinder 4 and a multi-layered non-woven fabric laminated outer layer 5. Further, the rotating shaft 2 is a member at the center of rotation of the negative pressure roll 1 and connected to the internal cylinder 3 by a reinforcement circular disk 9. Still further, the internal cylinder 3 is formed in a tubular shape and rotates together with the rotating shaft 2. In addition, the rotating shaft 2 and the internal cylinder 3 correspond to a rotating main body. Further, the intermediate cylinder 4 is a cylindrical tubular material formed outside the internal cylinder 3 and rotates in association with the rotating shaft 2 and the internal cylinder 3. Still further, the multi-layered non-woven fabric laminated outer layer 5 is formed outside the intermediate cylinder 4 and given as a part at which the negative pressure roll 1 is in contact with the metal strip 13. The multi-layered non-woven fabric laminated outer layer 5 also rotates in association with the rotating shaft 2, the internal cylinder 3 and the intermediate cylinder 4. In addition, the negative pressure roll 1 is provided with a controller 6 for suppressing rotation of the negative pressure roll 1.
