    摘要： A sealing-strip system has a sealing strip for sealing a suction zone of a suctioned roller in a machine for manufacturing and/or processing a fibrous web. The sealing strip has a wear volume which is successively removed by tribological contact with the roller, and a wear-indication unit which is formed by at least one tube which is configured in or on the sealing strip and which is at least in part disposed on or in the sealing strip in the region of the wear volume.

    摘要： In a paper-manufacturing machine a web is subjected to suction by placing a space between the web and a suction roll lapped thereby in communication with a region of substantially less than atmospheric pressure which is maintained at a part of the suction roll which is not lapped by the web. The structure includes a jacket which defines with the part of the suction roll which is not lapped by the web a hollow region with which a source of suction communicates. This hollow region of less than atmospheric pressure is situated at the exterior of the suction roll and bounded in part by an exterior surface of the suction roll, so that the hollow interior of the shell of the suction roll need not necessarily be utilized for providing the suction at the web.

    摘要： A wire is passed over the suction breast roll between the formed paper web and the doffer belt or the previously formed paper webs and doffer belt. The doffer felt is disposed in an unencumbered fashion over each of a plurality of consecutive suction breast rolls. The wire is removed from the web at a downstream point outside the dewatering influence of each breast roll. Stripping of the wire from the paper web is aided by various suction devices or couch rolls at this latter point.

    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 center (16). Thereby, the inner surface (48) of the mantle (44) assumes the shape of the envelope.

    摘要： A sealing device for sealing at least one underpressure or overpressure zone adjoining a surface which is moved in a movement direction in a paper, tissue or cardboard machine, includes at least one sealing element which is located opposite the moved surface and has at least one feed channel for a lubricant. In order to considerably decrease the wear of a sealing element uniformly over the entire length thereof, the at least one feed channel ends in a supply channel, which is arranged at the beginning of the sealing element in the movement direction.
