A vibration-minimizing suspension mechanism for a press roll is provided. The press roll and an opposing roll each having a rotational axis and cooperate to form a press nip for imparting a linear load on a web passing therethrough. The linear load is oriented through the rotational axes of the press and opposing rolls. The suspension mechanism comprises a suspension arm having opposed ends and a medially-disposed pivot, wherein the rotational axis of the press roll is rotatably engaged with one of the opposed ends. The suspension arm is pivotably and adjustably mounted at the pivot to allow the pivot to be adjusted in substantially parallel relation to the linear load. The adjustable pivot thereby allowing a mounting line, defined by the pivot and the rotational axis of the press roll, to be maintained in substantially perpendicular orientation to the linear load to thereby minimize vibration in the press roll. |

A method and a device for controlling a paper web which is leaving a press nip in the press section of a paper-making machine. The paper web is intended to follow a felt after the press nip. Control of the paper web is achieved in accordance with the teachings of the invention by preventing air admission to the side of the felt facing away from the paper web during the expansion phase of said felt after the press nip, whereby a pressure is generated, sucking the paper web against the felt. Air admission to the felt is prevented by means of an impermeable belt which is arranged to travel in a separate loop at the same speed as the felt. The belt extends closely adjacent the felt against the side thereof facing away from the web through one or several press nips and over a distance following said press nip/nips. |

An arrangement for equalizing the compression pressure acting on a web passing through a paper machine press nip formed by two opposed press rolls and through which of at least one press fabric passes. At least one resilient loop component passes through the press nip, the resilient loop component having an outer surface facing the web whose hardness is within the range of between 10 to 80 P & J by means of which smallsize variations in the compression pressure acting on the web in the range of up to about 6 mm are equalized. The resilient loop component has a framework layer within its thickness whose hardness is substantially greater than the hardness of the outer surface which faces the web by means of which larger variations in the compression pressure acting on the web are equalized. A press section incorporating the arrangement is also disclosed. |

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. |

A paper machine press section has an intermediate press nip defined between a pair of press rolls, a web conveying fabric in the form of a suitable felt or wire travelling between these press rolls together with a web carried thereby while engaging one of the press rolls. An endless fabric means in the form of a suitable felt or wire laps the other press roll to travel also through the intermediate press nip while engaging the web at the side thereof which is directed away from the web-conveying fabric. Thus, while travelling through the intermediate press nip, the web is compressed between the above fabrics. Immediately subsequent to the intermediate press nip, the web-conveying fabric together with the web conveyed thereby lap the press roll which engages the web-conveying fabric through an angle which is at least 5.degree. and which preferably is in a range of approximately 7.degree.-30.degree.. The roll which engages the web-conveying fabric is preferably a smooth-surfaced roll, while the other press roll has a recessed water-receiving recess formed, for example, by grooves, blind bores, or the like. |

The use of a pressure roll in a water control system for suction rolls generally and couch rolls particularly for a papermaking process of the type wherein water is removed from the wet paper web that has been run around the roll and wherein a surface tension covering is provided around the periphery of the couch roll on at least a portion of the couch roll and a water control zone is provided within the couch roll to control the water removed from the paper to the surface tension member with variations of the pressure within the water control zone to directionally control the discharge of water off the couch roll in a predetermined pattern for deposit in the water collecting pan provided in proximity to the couch roll.The pressure roll, having a new soft rubber covering, is mounted in face-to-face pressure engagement against the couch roll, with the pressure nip therebetween located in the water collecting zone preferably within one to one-and-a-half inches of the beginning of the water collecting zone. The pressure roll serves to counteract the natural tendency of the pulp fines to plug up the interstices of the wire mesh screen covering on the couch roll which would cause the water removal and water control action of the couch roll to be hampered. |
