  • Roll that can be bent with a composite shell
    Patent number: 6592503
    Abstract: A roll has a continuous tubular roll shell (11) of a composite material and axle journals (12) rotating together with the roll shell and joined to each end of the roll shell. The axle journals are supported on a supporting element (13) surrounding the axle journal (12) by at least two bearing elements (14, 15) located at a distance from each other in the axial direction (X—X) of the roll, which supporting element (13) for its part is supported on the machine frame structures (R). The first bearing element (14, 15) is supported on the supporting element (13) through a bending mechanism (20, 21), which is used for applying to the first bearing element (14, 15) a force affecting in a radial direction in order to deflect the first bearing element (14, 15) in relation to the central axis (X—X) of the unbent roll, whereby the axle journal (12) will bend in relation to a pivot point which is formed at the second bearing element (14, 15) and a bending moment is applied to the roll shell (11).

  • Roll that can be bent for a web-like material
    Patent number: 6524227
    Abstract: A roll that can be bent for a web-like material, which roll comprises a continuous tubular roll mantle (11) of composite material as well as axle journals (12) connected to each end of the roll mantle (11). The axle journals (12) are attached by means of at least one mechanism (30), by whose means the axle journals (12) and thereby the roll mantle (11) are bent into an arc form, and a regulation device (40) by whose means the angular position of the roll arc can be regulated.

  • Composite-construction roll and a method for manufacturing it
    Patent number: 6524229
    Abstract: 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.
