    摘要： A dewatering roll (10) comprises a roll body (20), a mantle support structure (30) and a mantle (40). The mantle support structure (30) is attached around the roll body (20). The mantle (40) is attached against an outer surface (36) of the mantle support structure (30). The mantle (40) has a plurality of through holes (42) constituting mantle flow paths (44). The mantle support structure (30) presents support flow paths (38) from the outer surface (36) of the mantle support structure (30). The support flow paths (38) are in fluid contact with the mantle flow paths (44). The outer surface (36) of the mantle support structure (30) has a static geometric shape defining an envelope having a smaller radius in vicinity of each axial end ( 15) than in vicinity of a centre (16). Thereby, the inner surface (48) of the mantle (44) assumes the shape of the envelope.

    摘要： A disc segment adapted to be attached to other disc segments to form a disc assembly, the disc segment including an isosceles trapezoid frame. The frame comprises a left side rail and a right side rail, and a plurality of spaced apart parallel horizontally extending ribs connected between the side rails. The frame defines a first disc side and an opposite second disc side, each disc side including a corrugated left bottom clamp list adjacent the left side rail and supported by the ribs, and a corrugated right bottom clamp list adjacent the right side rail and supported by the ribs. Each disc side also includes a corrugated wire mesh supported by the left and right clamp lists, and supported by the frame ribs.

    摘要： A device (10) is provided for preventing rewetting in a pulp washer (100), with two press rolls (2), arranged to rotate in opposite directions and having permeable outer surfaces (4), inside of which filtrate channels (6) are arranged. The device (10) comprises an anti-rewet beam (12), the cross-section of which forms a closed shape. The anti-rewet beam in turn comprises a filtrate barrier (12a) positioned towards the outer wall (6a) of the filtrate channel to prevent flow of liquid from the trailing part of the filtrate channel to the outer surface of the press roll, a support member (12b) positioned towards the rear side wall (6d) of the filtrate channel, and at least one intermediate beam portion (12c, 12c'), interconnecting the filtrate barrier and the support member, to form the closed beam shape.
