摘要： A press roll for acting in opposition to a counter roll. The press roll has a support member which is supported at its opposite ends. The support member is stationary in certain most embodiments and rotatable in one embodiment. A flexible, liquid-tight endless press jacket is wrapped around the support member. At each lateral end of the press roll, the press jacket is fastened to the outward end of a supporting disk, which is rotatably mounted on the support member. The lateral edge zones of the press jacket are both deformed radially inwardly around the outside of the respective supporting disks and each edge zone is clamped there by a annular clamping flange. To facilitate deformation of the edge zones, at least one of the edge zones terminates in a series of tongues separated by cutouts arrayed around the roll. Coiled tension springs engage the edge zone and/or the tongues to pull them in the direction toward the axis of the roll.

摘要： A process for the manufacture of a continuous press shell that is liquid-tight and smoothed on its inside, and which can be used as a press element in a dewatering press is provided. The press shell consists of a continuous wire belt which on its outside is coated with a plastic. Upon the smoothing of its outside, the coated press shell is turned, so that for the use of the press shell its smoothed surface will be on its inside. For turning the press shell, the one continuous edge of the press shell is first turned inward and attached to a traction device. Next, an adjoining and as yet unturned section of the press shell is held back on its outside, by means of vacuum, on a fixed guide device. Lastly, the traction device, along with the edge of the press shell attached to it, is pulled through the interior of the press shell.

摘要： 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.

摘要： A piston-cylinder arrangement, particularly useful for the press shoe of an extended nip press. The cylinder is a fluid pressure cylinder with a piston, which is fluid pressure reciprocated, disposed in the cylinder chamber. The cylinder and piston are polygonal around their peripheries. A circumferential groove in the cylinder wall carries a plurality of sealing pieces which are urged outwardly of the groove and against the periphery of the piston. The sealing pieces comprise corner pieces disposed at the corners of the polygonal cylinder and second sealing pieces joining the corner pieces. Where the corner and second sealing pieces meet around the periphery of the cylinder, they have overlying, overlapping surfaces that are oriented perpendicular to the reciprocation of the piston. A spring in the groove may urge some of the pieces outwardly toward the piston. Particular beveling or rounding of the slide surfaces of the sealing pieces and a particular thickness of the sealing pieces with respect to the groove are described.

摘要： In an extended nip proess including a stationary support member, a hydraulically actuatable press shoe supported on and extending along the support member and a rotatable counter-roll opposed to and extending along the direction of the press shoe, there is a flexible, tubular press jacket which rotates around the support member and which is sealed so as to be inflatable by air. Before rotation of the counter-roll starts, the press jacket is air inflated and expands to partially wrap around the counte-roll. After rotation of the counter-roll and the press jacket begins, and only after a set minimum velocity has been exceeded, then the press shoe is fluid pressurized against the press jacket. At the time, the air pressure in the press jacket is reduced. Various control devices control the feed of pressure liquid to the press shoe and the feed of air to the press jacket until and then after a minimum speed level is exceeded.

摘要： 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. Furthermore, control circuits may be provided, one for sensing the temperature of the liquid removed from the press belt and controlling the cooling of the press belt, and another for sensing the pressing surface temperature and controlling its cooling.

摘要： A paper machine includes a double-felt (or single-felt) wet press. Two press elements, for instance two rolls, whose axes lie in a press plane, form a press nip with each other. Two endless felt belts, and between them the paper web from which the water is to be removed, pass through said nip. Beyond the press nip the paper web travels, free of the felt belts, to the next station of the paper machine. Each of the two felt belts travels beyond the press nip over a guide element, which can be a guide roll or a nonrotating deflector, whose position is displaceable parallel to the press plane. The arrangement is operated as follows: The angle between the paper web and the wetter felt is set to a smaller value during the initial licking-up process than during the subsequent continuous operation. On the other hand, the angle between the paper web and the drier felt is set to a larger value during the initial licking-up process than during the subsequent continuous operation.
