Abstract (en)

The invention relates to a sleeve roll for a wire section of a fiber web machine. The sleeve roll (21) includes a stationary axle (28) and two circular roll heads (29) supported on the stationary axle (28) and arranged to rotate. The sleeve roll (21) further includes a belt loop (30) arranged around the stationary axle (28) and tensioned between the roll heads (29). There is also a curvilinear forming element (22) arranged between the stationary axle (28) and the belt loop (30). Said forming element (22) is in contact with the belt loop (30) in order to form rising pressure for water removal. Before the forming element (22) in the rotating direction of the belt loop (30) there is a lubricated sliding surface (31) for fabric support and lubrication of the forming element (22).
