    Abstract: A fiber web transferring device comprising a conveyor belt, a suction cylinder, a lower calendering cylinder and an upper calendering cylinder. The suction cylinder having a stationary suction sector and rotates in a direction which corresponds to a linear moving direction of the conveyor belt. The suction cylinder transfers a non-consolidated fiber web from the conveyor belt to the lower calendering cylinder and is substantially tangential to the lower calendering cylinder so as to cooperate therewith to define a pre-calendering zone for the fiber web. The suction cylinder is positioned such that the suction cylinder sucks the fiber web from the conveyor belt and holds the fiber web against the outer surface of the suction cylinder to the pre-calendering zone. The fiber web then adheres to the outer surface of the lower calendering cylinder past the pre-calendering zone until the fiber web reaches the upper calendering cylinder.
