Abstract
Disclosed is a touch roll () including: a center rotary shaft (); fixed end plates () concentrically disposed in two places which are away from each other in an axial direction of the center rotary shaft; an external cylinder () made of a metal-made thin film and rotatably supported, at two ends thereof, by the respective fixed end plates, the external cylinder being concentric with the center rotary shaft; and multiple rolling rubber rolls () each rotatably supported, at two ends thereof, by the respective fixed end plates, the plurality of rolling rubber rolls being in sliding contact with an outer peripheral surface of the center rotary shaft, and being in sliding contact with an inner peripheral surface of the external cylinder. In the touch roll, the rolling rubber rolls divide an annular space between the external cylinder and the center rotary shaft into multiple heating medium chambers arranged in a circumferential direction of the touch roll; and the rolling rubber rolls are configured in a way that each of the multiple heating medium chambers is filled with a heating medium.
