Device for a drying section useful in the manufacture of paper or paperboard as a fibrous web. The drying section includes a drying drum rotatable about a first axis of rotation and arranged such that the fibrous web runs in contact with a surface of the drying drum, at least about a part of its circumference, and is dried thereby. The device includes at least one press roller rotatable about a second axis of rotation which is essentially parallel with the first axis of rotation, and is arranged, with a line load, to bear against the fibrous web, whereby the drying drum supports the at least one press roller. The at least one press roller is positioned at a corresponding longitudinal edge of the fibrous web, the least one press roller having a first cross-sectional diameter (D) at outer short ends in the device, and a second cross-sectional diameter (d) at inner short ends of the device, the first cross-sectional diameter (D) being larger than the second cross-sectional diameter (d). |
