A composite-construction roll, includes a roll frame reinforced with reinforcing fibers, and a method for manufacturing such a roll. There is at least one optical fibre among the reinforcing fibers and the roll includes terminals arranged in this optical fibre for a transmitter and a receiver for measuring a selected optical quantity from the fibre.

Composite-construction roll and a method for manufacturing it

A roll that can be bent for a web-like material, which roll comprises a continuous tubular roll mantle ( ) of composite material as well as axle journals ( ) connected to each end of the roll mantle ( ). The axle journals ( ) are attached by means of at least one mechanism ( ), by whose means the axle journals ( ) and thereby the roll mantle ( ) are bent into an arc form, and a regulation device ( ) by whose means the angular position of the roll arc can be regulated.
