A rotary drum apparatus comprises a drum that is rotatable about an axis of rotation. The apparatus comprises a first set of first shell segments having a first number of first shell segments. Each first shell segment is releasably connectable with the drum and has an outer surface. The outer surfaces of the first shell segments combine to form a continuous first outer circumferential surface defining a maximum radial distance from the axis of rotation. The apparatus comprises a second set of second shell segments having a second number of second shell segments. Each second shell segment is releasably connectable with the drum and has an outer surface. The outer surfaces of the second shell segments combine to form a continuous second outer circumferential surface located within 10% of the maximum radial distance. The first number of first shell segments is greater than the second number of second shell segments.

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.
