| 168 | Pressing device for extracting liquid from a pulp web | US423888 | 1995-04-18 | US5577441A | 1996-11-26 | Joachim Grabscheid |
| A pressing device for extracting water from a pulp web comprises two press rolls that form between them a nip and that are arranged to extend substantially in parallel one to the other in the unloaded condition. The first press roll has its two ends supported in first bearing blocks and is stationarily fixed in the axial direction at least on one end. The second press roll is supported by its two ends in two bearing blocks. The first bearing blocks and the second bearing blocks can be braced one to the other by tension members which allow the press rolls to perform a relative movement in the axial direction under load. One of the second bearing blocks is secured against displacement in the axial direction on the lower first bearing block, by an articulated joint acting preferably on the middle of the longitudinal extension of the tension element. This minimizes the bending stress exerted on the tension elements and distributes it uniformly over the two ends of the tension elements, provided a central point of attack is selected for the articulated joint. | ||||||
| 169 | Press roll having components exhibiting approximately equal gravity induced flexure | US17759 | 1993-02-16 | US5329847A | 1994-07-19 | Christian Schiel |
| A press roll in cooperation with a mating roll defines a roll nip for the treatment of a moving web of material with the press roll and mating roll being oriented to provide a non-vertical pressing plane. The press roll includes a rotatable roll casing and a yoke located within the roll casing. The roll casing and the yoke defining an intermediate space therebetween. Certain press roll parameters such as the dimensions and material of the roll casing and the yoke and/or the degree of filling of the intermediate space with a liquid are selected such that gravity induced flexures of the roll casing and the yoke occurring in a median plane perpendicular to the pressing plane are approximately equal. | ||||||
| 170 | Wet press nip with nonrotating adjustable belt exit guides | US164540 | 1988-03-07 | US4909903A | 1990-03-20 | Josef Mullner |
| 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. | ||||||
| 171 | Procedure and means in the treatment by pressing of a fibre web, in particular of a paper or cardboard web | US638683 | 1984-08-08 | US4586983A | 1986-05-06 | Jorma Laapotti |
| A pressing method and apparatus for dewatering a fibre web, such as a paper or cardboard web, in a paper machine press section including two press rolls through which the web is conducted carried on either a single fabric or interposed between a pair of fabrics. The web is pre-pressed in a pre-pressing zone located in the throat region between the press rolls. The pre-pressing pressure is applied to the web through the mediation of a substantially impermeable band which passes through the press nip in overlying relationship with the web as the latter is conducted over a sector of one of the press rolls. After the pre-pressing step, the web is immediately conducted through the zone of the press nip, the pressing of the web which takes place in the press nip determining the dry matter content of the web subsequent thereto. The pre-pressing zone immediately precedes the zone of the press nip so that the pre-pressing and nip zones together in combination constitute a pressing zone. The peak pressing pressure present in the press nip zone is greater than the pressure in the preceding pre-pressing zone. | ||||||
| 172 | Method and means for removing water from a web in a press of a papermaking machine | US653815 | 1984-09-24 | US4555306A | 1985-11-26 | Kristian Lundstrom |
| The invention relates to a method and means for removing water from a web in a press of a papermaking machine. The web to be dried is passed between press felts through a press nip formed between press rolls. A resilient mat or the like, which is in contact with one of the press felts, is also passed through the press nip. In order to produce a hydraulic counterpressure at the nip, a wire is passed between the resilient mat and one of the press rolls and water is sprayed on the wire immediately before the press nip for producing a water cushion in the section of the wire lying between the press roll and the resilient mat. The wire is in this case formed so that water cannot move in the longitudinal or vertical direction of the wire. | ||||||
| 173 | Multi-press for the dehydration of sheet products | US166734 | 1971-07-28 | US3997391A | 1976-12-14 | Giuseppe Ortolani |
| A multi-press for removing water from sheet material such as paper, comprises a suction cylinder comprising a stationary internal cylinder and a rotatable external cylinder thereon that is permeable to the passage of fluid therethrough. The stationary internal cylinder is divided into a plurality of isolated sectors of equal volume that communicate with the rotatable cylinder through slots extending longitudinally of the stationary cylinder. Separate valves individually control the vacuum in each of the isolated sectors. Equally peripherally spaced pressing cylinders press superposed webs with wet sheet material between them, against the periphery of the rotatable cylinder. The pressing cylinders are disposed one adjacent each of the slots. | ||||||
| 174 | Double-felted press | US3607626D | 1969-09-10 | US3607626A | 1971-09-21 | NILSSON JAN PETER |
| A double-felted press for a papermaking machine or the like comprises a pair of press rolls arranged to form a nip and an endless press felt trained around a segment of each of the rolls, the press felts passing through the nip. One of the rolls is a suction roll, and the suction zone is located entirely on the downstream side of the roll, relative to the direction of rotation of the roll, from the nip, is contiguous or in proximate relation to the nip, and is within the segment of the roll over which the felt for that roll is trained. A guide roll for the felt associated with the other press roll (the nonsection-roll is normally positioned such that the felt is separated from the web being pressed before the web reaches the suction zone of the suction roll but is arranged to be moved to a position training that felt around the suction zone of the suction roll so that the two felts turn around the suction zone of the suction roll and ensure that the web runs with the suction-roll felt. Normally, the two felts are trained to run together over the suction zone of the suction roll only upon startup of the machine.
