摘要： A method for drying a fibre web, said method comprising passing the fibre web with at least one paper machine fabric between two bands which move in parallel, said bands having a good thermal conductivity and being impermeable to air, in such a manner that the fibre web is in contact with the first band (1) to be heated and a paper machine fabric (9) is in contact with the second band (4). The method comprises heating the first band with pressurized hot water, and cooling the band to be cooled with water having substantially the same pressure and lower temperature.

摘要： A top roll lifting arrangement for a roll press in a press section of a papermaking or boardmaking machine where the roll press includes a top roll (1) and a bottom roll (2), the rolls being opposed and parallel and having main axes defining a press plane (P) and forming between them a press nip (N). The press has a framework including two side frames (6) in parallel relationship to each other, one located on the drive side of the machine and the other one on the tender side of the machine. Each side frame has a first vertical column (7) upstream of the press nip and a second vertical column (8) downstream of the press nip. The upper roll (1) is carried by a bracket (10) extending between the upstream and downstream vertical columns (7, 8). The brackets have bevelled ends (33) that co-operate with inclined surfaces (32) of plate members (31) on the vertical columns.

摘要： A press belt in the form of an endless loop includes crosswise and lengthwise reinforcing fibers. The crosswise reinforcing fibers (16) are positioned adjacent to the outside surface of the belt (10) and the lengthwise reinforcing fibers (18) are positioned adjacent to the inside surface of the belt (10). The fibers (16, 18) are laid inside a casting cylinder and an elastomeric material (20) is cast onto the fibers (16, 18) while the casting cylinder is rotating. The crosswise fibers (16) are laid into the casting cylinder first so that they are adjacent to the outer surface of the belt and then the lengthwise fibers (18) are laid over the crosswise fibers (16).

摘要： A press shoe for a shoe press with extended nip, said press shoe is of combined hydrostatic and hydrodynamic type and has a plurality of hydrostatic pressure pockets (18), each of which is preceded by a leading land surface (19) and followed by a trailing land surface (20) and into which lubricant is supplied under pressure. According to the invention each pressure pocket (18) has a first pocket zone (26) in which a hydrodynamic pressure shall be created and which comprises a bottom surface (28) located at gradually decreasing depth from the concave surface portion (4) of the press shoe (3) seen in the direction of rotation of the belt member (1), said depth being zero at the trailing end (t6) of the pressure pocket (18). The bottom surface forms an angle α of from 0° to about 2° with a tangent (29) to the concave surface portion (4) of the press shoe (3) at the trailing end (t6) of the pressure pocket (18). Further, the first pocket zone (26) is preceded by a second pocket zone (27) comprising a plane bottom surface (30) forming an angle β of from 0° to about ±10° with a plane that coincides with the bottom surface (28) of the first pocket zone (26).

摘要： An enclosed extended nip press apparatus (10) is disclosed for pressing water from a formed web (W). The apparatus (10) includes a frame (12) and a backing roll (14) rotatably secured to the frame (12). A press member (16) cooperates with a backing roll (14) for defining therebetween an extended nip (N) for the passage therethrough of the formed web (W). A press blanket (18) extends in a closed loop through the nip (N), the blanket (18) having a first and a second lateral edge (20, 22) and an inner and an outer surface (24, 26). A first and a second head (28, 30) are rotatably secured to the press member (16) with the first and second heads (28, 30) being disposed adjacent to and cooperating with the first and the second edges (20, 22) respectively of the blanket (18). The first and the second heads (28, 30) define first and second annular channels (32, 34) respectively for the reception therein of the first and the second lateral edges (20, 22) respectively of the blanket (18). A first and a second annular seal (36, 38) are disposed within respectively the first and the second channels (32, 34) with the seals (36, 38) contacting the respective edges of the blanket (18). A first and second plurality of barbs (40, 42) extend from the first and the second channels (32, 34) respectively such that the first plurality of barbs (40) extend towards and engage the first lateral edge (20) of the blanket (18) and are disposed on the opposite surface (26) of the blanket (18) relative to the first seal (36). The second plurality of barbs (42) extend towards and engage the second lateral edge (22) of the blanket (18). The second plurality of barbs (42) are disposed on the opposite surface (26) of the blanket (18) relative to the second seal (38) so that during use of the apparatus (10), lateral movement of the edges (20, 22) of the blanket (18) relative to the heads (28, 30) is inhibited.

摘要： An extended nip press for papermaking machine extracts water from a web of paper on a forming felt (14) passing over a backing roll (15) employing electromagnetic repulsion forces. In one embodiment, a belt (20) is formed with permanent magnets which have thickness oriented poles and a like pole (30, 31) is provided external to the belt surface in non-contacting relation to provide a repulsion force to the belt which is transmitted by the belt to the felt and the paper. In another embodiment, the belt (20) is formed of current-carrying nonferrous material and a repulsion force is formed by inducing current to flow in the belt (20) by causing current to flow in an adjacent coil in non-contacting relation to the belt. In either embodiment, air pressure housing (40) may be positioned over the electromagnet (30) or conductor, to cool the electromagnet (30) and to apply an air pressure force against the belt (20) in the same direction as that of the induced or repulsion force.

摘要： An extended nip press (20) has a shoe (26) driven by two pistons (36, 38) to engage a blanket-supported web (33) against a crown controlled roll (24). Each ENP shoe piston (36, 38) is offset from the line of force application (60) of the crown control piston (48) by a moment arm distance (X, Y). A balancing of the hydraulic pressures in the ENP shoe cylinders and the crown control cylinder is achieved by two equalizer valves (65, 54). Each valve has a slidable spool with faces of a selected cross-sectional area to respond to hydraulic fluid from the various cylinders to retain the correct proportion between the forces applied by the ENP shoe pistons and the crown control piston.

摘要： The grooves of a grooved press belt are formed with an improved configuration which reduces groove closure under pressure and which reduces cracking and tearing of the belt. The improved groove configuration consists of a curved bottom (20) and two upwardly diverging side walls (22). In a first embodiment the bottom wall is semi-circular and has a diameter (D) which is equal to about one half of the width (W) of the groove opening. The upwardly diverging side walls (22) preferably include radiused upper edges (24). The side walls (22) preferably have an angle of divergence between about five degrees and about fifteen degrees from a vertical plane. In a second embodiment, the bottom of the groove is substantially flat, and the bottom corners are radiused to provide a smooth transition between the flat bottom and the upwardly diverging side walls.

摘要： An extended nip press apparatus (10) is disclosed for removing water from a web (W). The apparatus (10) includes a rotatable backing roll (12) and an elongate shoe (14) which cooperate with the backing roll (12) for defining therebetween an extended nip (16) for the passage therethrough of the web (W). The shoe (14) defines a concave surface (18). A bearing blanket (20) is movably disposed between the backing roll (12) and the concave surface (18). The arrangement is such that the web (W) is supported by the blanket (20) with the web (W) being disposed between the blanket (20) and the backing roll (12). A lubricant (26) is supplied between the concave surface (18) and the blanket (20) such that the blanket (20) is slidingly supported by the concave surface (18) during passage of the blanket (20) through the extended nip (16). The concave surface (18) encompasses a pocket (28) defined by the shoe (14). The arrangement is such that the pocket (28) is filled with lubricant (26) flowing from the concave surface (18) so that in the event of a wad of the web entering into the extended nip (16), the wad is yieldingly received within the pocket (28) so that damage to the blanket (20) by the wad is minimized.
