In a paper or board machine drying line after the wire section, during dewatering a web's (W) width is affected in a direction crosswise to the web's traveling direction. Starting from an edge, at least one device (A,B) brings about a force effect of a desired magnitude which is directed all the way to a desired arbitrary crosswise web position in order to modify web characteristics. A device in a paper or board machine line after the wire section has means for processing the web and for dewatering. The paper or board machine line after the wire section further has at least one device (A;B) for directing a force effect at a desired partial area (WS) of the web (W) in the cross machine direction in order to modify the web's characteristics profile in the cross machine direction.

The invention concerns a connecting structure ( ) between a driving transmission ( ) and a roll ( ) driven through it. The driving transmission ( ) includes an input shaft ( ) in the drive, whereby through the input shaft ( ) the drive is transferred to toothed gears and further to the roll jacket ( ) of the driven roll ( ) to rotate it. The roll ( ) includes a central static shaft ( ) and a bearing (G) to support it. In order to allow axial and radial motions of the roll's ( ) roll jacket when the driving transmission ( ) is in the fixed position, a seal ( ) including a sliding ring ( ) is fitted in between the driving transmission ( ) and the roll ( ).
