Abstract
A roll has a continuous tubular roll shell ( ) of a composite material and axle journals ( ) rotating together with the roll shell and joined to each end of the roll shell. The axle journals are supported on a supporting element ( ) surrounding the axle journal ( ) by at least two bearing elements ( ) located at a distance from each other in the axial direction (X—X) of the roll, which supporting element ( ) for its part is supported on the machine frame structures (R). The first bearing element ( ) is supported on the supporting element ( ) through a bending mechanism ( ), which is used for applying to the first bearing element ( ) a force affecting in a radial direction in order to deflect the first bearing element ( ) in relation to the central axis (X—X) of the unbent roll, whereby the axle journal ( ) will bend in relation to a pivot point which is formed at the second bearing element ( ) and a bending moment is applied to the roll shell ( ).
