The invention claimed is: 1. An arrangement in connection with supporting a press roll, the press roll including a support shaft extending through a rotating roll shell in an axial direction and being supported using at least one bearing element in at least one bearing point to a support frame form
The invention claimed is: 1. An arrangement in connection with supporting a press roll, the press roll including a support shaft extending through a rotating roll shell in an axial direction and being supported using at least one bearing element in at least one bearing point to a support frame formed as a bearing block, and the arrangement comprising: at least one torque support for preventing the rotation of the support shaft, wherein the at least one torque support is arranged to at least one of the bearing points inside a bearing housing or equivalent, wherein the at least one torque support is arranged through the bearing element between the support frame and the support shaft and at least one counterbore or equivalent is arranged to the support shaft for accommodating an end of the torque support, wherein the end of the at least one torque support and the at least one counterbore of the support shaft are formed in shapes in order to lead forces from the support shaft via the at least one torque support to the support frame, and wherein a shape of portion of the at least one torque support is adapted so that the at least one torque support is able to rotate around an axis thereof, thereby enabling a deflection of the support shaft. 2. An arrangement according to claim 1, wherein at least one opening formed as a hole, is arranged to the bearing element. 3. An arrangement according to claim 1, wherein through a wall of the bearing housing is arranged at least one opening formed as a hole at a centre line of the bearing housing, is the at least one opening being horizontally arranged in a machine direction MD. 4. An arrangement according to claim 1, wherein the at least one counterbore of the support is arranged in a bearing line of the press roll, the at least one counterbore being horizontally arranged in a centre line of the press roll. 5. An arrangement according to claim 1, the wherein at least one opening is arranged through a wall of the bearing housing, the at least one opening of the bearing element, and the at least one counterbore of the support shaft is arranged in incidence so that the torque support is set in position. 6. An arrangement according to claim 1, wherein the bearing element comprises a spherical surface which has at least one permeating hole formed horizontally on a centre line of the at least one bearing point. 7. An arrangement according to claim 1, wherein the support shaft is internally torque-supported by the at least one bearing point, and is one- or multi-part. 8. An arrangement according to claim 1, wherein the support shaft is internally torque-supported by the at least one bearing point, and is central or non-central in relation to a surface of the press roll. 9. An arrangement according to claim 1, wherein, in a first end of the press roll, the at least one counterbore having such a shape which is adapted to lock the bearing housing and the press roll in relation to each other, and to allow only a CD-directional deflection (Δy) of the press roll, and only in a predetermined amount a deflection (Δx) occurring in a machine direction MD of a web. 10. An arrangement according to claim 1, wherein, at an opposite end in relation to a first end of the press roll, the at least one counterbore having a shape which allows thermal expansion of the press roll during operation, and also allows a length variation related to precision of manufacture of the press roll. 11. An arrangement according to claim 1, wherein the at least one torque is totally inside the bearing housing. 12. An arrangement according to claim 1, wherein the at least one torque support allows a deflection of the press roll in a cross-direction CD direction of a machine. 13. An arrangement according to claim 1, wherein the at least one torque support allows the press roll to deflect by a predetermined amount in a machine direction MD of a web. 14. An arrangement according to claim 1, wherein the at least one torque is form-machined to fit to the at least one counterbore of the support and at least one opening of the bearing housing. 15. An arrangement according to claim 1, wherein, on side surfaces of the bearing housing, there are form-machining counterbores for locking elements of the at least one torque support. 16. An arrangement according to claim 1, wherein there are one or more locking elements, according to a number of the at least one torque support. 17. An arrangement according to claim 1, wherein locking elements lock the at least one torque support inside the bearing housing.
