Abstract (en)
[origin: EP2540649A1] The invention relates to a method in connection with an unwinder (5) for a fiber web(W), according to which method a machine roll (10) is unwound to a fiber web (W) in the unwinder (5) and in which method the machine roll (10) is unwound in a first unwinding station of the unwinder (5) on first rails (17) down to a certain diameter and the machine roll (10) is unwound in a second unwinding station of the unwinder (5) on second rails (16) down from the certain diameter. The machine roll (10) is transferred from the first unwinding station on the first rails (17) to the second unwinding station on the second rails (16) during unwinding such that at least once during transferring the machine roll (10) is moved in its axial direction (S) while supported on movable / inclinable rail parts (15) between the first and the second rails (17; 16). The invention also relates to an arrangement in connection with an unwinder (5) for a fiber web(W), which unwinder (5) comprises a first unwinding station on first rails (17) for unwinding a machine roll (10) down to a certain diameter and a second unwinding on second rails (16) for unwinding the machine roll (10) down from the certain diameter. The unwinder (5) further comprises movable / inclinable rail parts (15) between the first rails (17) and the second rails (16) which first and second rails (17; 16) are not located on the same longitudinal line for providing transferring of the machine roll (10) from the first unwinding station on the first rails (17) to the second unwinding station on the second rails (16) during unwinding such that at least once during transferring the machine roll (10) is moved in its axial direction (S) while supported on movable / inclinable rail parts (15).
