Abstract: A long-nip press roll and a mating roll form an areal press nip with each other. The long-nip press roll has a flexible tubular press shell which is mounted by means of two support disks on a stationary support member which extends through the inside of the press shell. Within a hydraulic pressure chamber provided on the supporting member is a radially displaceable press shoe which can press the press shell against the mating roll. Support member, pressure chamber and mating roll are arranged symmetrically relative to a press plane. The slide surface of the press shoe which contacts the press shell is arranged offset with respect to the press plane in the direction opposite the direction of travel of the press shell. The axis of rotation of the press shell and its two support disks is also arranged offset out of the press plane in the direction opposite the direction of travel of the press shell.

Abstract: A continuously working press is provided having a rolling rod conveyor connected to a guide chain, whereby in the critical entering arc and also in the tangential transition into the horizontal pressing zone the guide chain has the same arc dimension and secant dimension as the rolling rods, because they are guided coaxially with the same radius via entering gear wheels and lead-in gear wheels. Consequently, the orientation of the rolling rods orthogonal to the feeding direction is maintained. Furthermore, the rods are kept exactly equidistant during the transition from the entering arc into the horizontal pressing plane. Linear shifts are absorbed in an elastically compensating manner by bearing bolts composed of spring steel. The high spring forces which occur in the bearing bolts as a result of linear shifts of the rolling rods are absorbed in a compensating manner by thick sleeves and sextuple plate stacks of the guide chain.

Abstract: In a wet press for dewatering a web of material, for instance a paper web, a contact pressure device is provided which presses against a rotating roll and exerts an incrementally increasing pressure in the direction of travel of the paper web. The contact pressure device comprises only a single pressure element arranged in the direction of travel of the paper web. The pressure element has two or more pressure pockets arranged sequentially in the direction of web travel and which are connected with a common pressure chamber by conduits. The increasing contact pressure is attained by arranging the pressure element unsymmetrically in relation to the pressure chamber. The effective pressure cross-sectional areas of pressure pockets arranged sequentially in the direction of web travel can additionally be reduced in the direction of web travel or the cross-sections of the associated bores can be increased.

Abstract: An extended nip press for removal of water from a web of fibers experiences a press shoe expansion and deformation problem due to uneven heating of the press shoe under load. The press nip includes a rotatable press roll, which is opposed to a press shell or jacket that rides over a press shoe that is supported in a recess on a supporting member. The press shoe has an upper part with a top surface on which the press belt slides through the press nip and has a lower supporting part. The upper and lower parts are heat insulated by an inserted insulating layer. The upper and lower parts are form locked by a spline connection toward the inlet side of the press nip. To avoid heat-caused deformation of the press shoe, the lower supporting part has a greater moment of resistance against flexure than the upper part due to their respective cross-sections.

Abstract: The invention relates to a process and a device for laminating of one sheet on the other sheet. The sheets to be laminated are underpinned and guided to an abutment, so that no breakdowns can occur even with unstable paper.

Abstract: Paper and paperboard which have been thoroughly dried but not calendered is provided with a smooth surface by rewetting a thin layer (5% to 10% of the thickness) along the surface and then pressing the resulting damp surface against a substantial portion of the surface of a heated dryer drum or other smooth-surfaced cylinder. This technique provides the web with a surface comparable in smoothness with what can be obtained by calendering but without the degree of compaction which occurs in calendering, due to the fact that with the major portion of the web dried, it is highly resistant to such compaction. The same method steps can be applied subsequently to the reverse side of the web to provide it with two smooth surfaces. It is also possible to forego the rewetting step if the initial drying of the web is unsymmetrical so that one surface remains wetter than the remaining portion of the web.

Abstract: A belt press for use in removing water from sewage sludge, and including a frame, a pair of belts for compressing sludge material therebetween, the said belts being water-permeable whereby water in said sludge may drain through said belts, and a gravity belt thickener adjacent the belt press.

Abstract: The invention relates to a method and a device for reducing the rewetting of a web after a press nip. The web to be dried is passed together with a press felt through a press nip formed by a first and a second press roll. The web and the felt are separated from each other after the press nip. For reducing the compressive pressure as quickly as possible after the center line of the nip, a mat made of a water-impermeable and resilient material is arranged to pass through the nip, said mat being in contact with the surface of either press roll and one of the surfaces of the web. After the press nip, the mat is subjected to a tensile stress, preferably by means of a second pair of rolls for preventing the returning of the mat to its original thickness starting immediately after the center line of the press nip.

Abstract: The belt press unit of a paper machine includes an elastic tubular press belt which passes around the circumference of and is spaced from the surface of a hollow, annular supporting body. A press shoe in the supporting body presses outwardly and urges the press belt against an opposing surface on a mating roller for defining a press nip. Circumferentially outside of the press zone, each of a plurality of circumferentially spaced guide ledges extends across the direction of travel of the belt. A torsionally rigid beam extends through and is attached at two axially spaced locations along the hollow of the annular supporting body. At least one of the guide ledges is supported to the beam, whereby radial deflection of the supporting body does not result in radial deflection of the beam and thus does not cause radial shifting of the guide ledge. The beam is axially displaceable with respect to the supporting body.

Abstract: The disclosure concerns a press device for a paper making machine, and particularly concerns an extended nip press. A hollow tubular, stationary support body extends around a supporting beam, which is a flexing beam. Hydraulic piston-cylinder combinations extend between the beam and the supporting body in a press plane. A radially non-displaceable press shoe is supported on the support body and faces toward a counter-roll to define a press nip between them. The outwardly facing surface of the press shoe is concave in the circumferential direction of the support body. The amount of pressure in the hydraulic supporting means determines the press force which prevails in the press zone.

Abstract: In a wet press for dewatering a web of material, for instance a web of paper, a contact pressure device presses against a rotating roll and exerts a pressure which increases in the travel direction of the web of paper. For this purpose, several rows of contact pressure elements are arranged sequentially in the travel direction of the web of paper. In each row the contact pressure elements are arranged side by side transversely to the travel direction of the web of paper. In order to circumvent a differential dewatering at the location of the contact pressure elements and at the gaps between the contact pressure elements of a row, the contact pressure elements of successive rows are shifted or staggered in relation to one another transversely to the web of material such that they mutually overlap. This prevents the arisal of strips in the paper being processed.

Abstract: In a belt pressing unit, which preferably serves as wet press of a paper machine, an elastic tubular press belt travels around a supporting body and, together with a back roll, forms an extended press zone. Beyond the press zone along the path of the press belt, liquid is fed to the inner side of the press belt in order to cool the press belt. This liquid is permitted to travel, together with the press belt, around the supporting body. Most of the liquid is then removed from the press belt, preferably at a position in front of the press zone. The liquid may then be cooled and fed back to the press belt. In addition, liquid may also be fed to the inner side of the press belt where the press belt enters the press zone, for cooling and lubricating a pressing surface of a press shoe which presses the press belt toward the back roll.
