Abstract
A roll for thermal and mechanical treatment of a web-shaped product, for example paper, comprises a roll body (1), thermal treatment conduits (2), insulating devices (4, 5; 4a, 5), a trunnion flange (3), and actuators (8). The insulating devices are capable of elongation in the thermal treatment conduits in the longitudinal direction of the conduits. The treatment conduits are for a thermal treatment fluid and are oriented in the roll body in the vicinity of the surface of the roll body. The trunnion flange is applied to the roll body, and the actuators are mounted in the trunnion flange and connected to the insulating devices. The actuators are mounted shiftable and fixable in the longitudinal direction of the thermal treatment conduits and are connected to the insulating devices for joint shifting.
