SLEEVE ROLL FOR WIRE SECTION OF FIBER WEB MACHINE

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). 本发明涉及一种用于纤维幅材机的网部的衬套辊。所述衬套辊(21)包括固定轴(28)以及两个圆形的辊头(29)，所述辊头被支撑在固定轴(28)上并且被布置成旋转。所述衬套辊(21)还包括带环(30)，所述带环围绕固定轴(28)布置且在辊头(29)之间张紧。还有布置在固定轴(28)与带环(30)之间的曲线形的成形元件(22)。所述成形元件(22)与带环(30)接触，以形成用于脱水的升高压力。在带环(30)的旋转方向上，在成形元件(22)之前，具有润滑的滑动表面(31)，所述滑
