A suction roll device (1) has a rotating shaft (2), an inner cylinder (3), an intermediate cylinder (4), and an outer layer (5). The inner cylinder (3) is supported by the rotating shaft (2) with a reinforcement circular plate (9) therebetween and has a negative pressure conduction groove (14) in the surface of the inner cylinder (3). Air within the negative pressure conduction groove (14) is sucked by a vacuum pump through a negative pressure conduction hole (8) formed in the inner cylinder (3). The intermediate cylinder (4) is formed on the outside of the inner cylinder (3) and has a large number of air passage holes (16) connecting to the negative pressure conduction groove (14). The outer layer (5) is formed on the outside of the intermediate cylinder (4) and comprises overlaid sheets of nonwoven fabric. The inner cylinder (3), the intermediate cylinder (4), and the outer layer (5) rotate together with the rotating shaft (2). A metallic band plate (13) which is pulled by a re-coiler (24) is sucked to the surface of the outer layer (5), and the rotating shaft (2) is braked by a braking device (6). As a result, tensile force is applied to the metallic band plate (13).
