    Abstract: A method and arrangement for computing and regulating distribution of linear load in a multi-nip calender. A material web is passed through the nips in a set of rolls including a variable-crown upper roll, a variable-crown lower roll and intermediate rolls positioned between the upper and lower rolls. The rolls in the set of rolls are supported so that, when the nips are closed, the bending lines of the rolls are curved downwards. When computing and regulating the linear loads, one or more of the physical properties affecting the bending of each intermediate roll under load, such as bending rigidity, mass, shape, and material properties, are taken into account. The ratio of the linear loads applied to the intermediate rolls, the weight of the rolls per se, and/or the support forces applied to the rolls are regulated so that the set of rolls is in a state of equilibrium and a predetermined state of deflection.

  • Patent number: 6782811
    Abstract: Extended-nip roll press for dewatering a material web comprises a rotating mating roll and an extended-nip press roll. The extended-nip press roll has a stationary support and a flexible roll cover which rotates about the support. A press shoe is arranged on the support, and the roll cover has end sections which are clamped firmly on rotatable end walls on the support. End wall clamping rings respond to a first actuating device and clamp a resilient spreader ring radially against an outer ring that can be connected firmly to the end walls. A sealing ring is arranged on each end wall adjacent the clamping ring and can be deformed radially against the outer ring by means of a second actuating device.

  • Patent number: 6764578
    Abstract: 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 adapted to impart a linear load on a fiber web passing therethrough. The linear load is oriented through the rotational axes of the press roll and the opposing roll. As such, the suspension mechanism comprises a suspension arm having opposed ends and a medially-disposed pivot, wherein the press roll is rotatably engaged at the rotational axis thereof with one of the opposed ends of the suspension arm. The suspension arm is further pivotably and adjustably mounted at the pivot so as to allow the pivot to be adjusted in substantially parallel relation to the linear load.

    Abstract: The invention relates to a method for controlling a surface quality variable (300) in one or more fibre webs (3) in a shoe calender (1) comprising one or more calender nips. In each calender nip of the shoe calender, the overall loading pressure of the shoe element (8) and the loading pressure difference between the leading edge (8′) and the trailing edge (8″) of the shoe element are controlled so as to achieve minimum difference between the determined values (300″) for the surface quality variables of the fibre web and the set values (300′) for the same quality variables after the shoe calender.

  • Patent number: 6513424
    Abstract: A pair of compression rollers 38a and 38b parallel with each other are provided and powder grains are supplied to a powder grain introduction/compression part 50 formed between the rollers 38a and 38b and, thereby, compression moldings of the powder grains are formed. A powder grain press/feed means 20 is provided in a front stage of the rollers 38a and 38b. The press/feed means 20 has a deaerating barrel 24 and previously presses the powder grains supplied between the rollers 38a and 38b. In side surfaces of the rollers 38a and 38b, side seals 37 are arranged with clearances 72 maintained from the rollers 38a and 38b. During pressing the powder moldings, the powder grains enter into the clearances so that closer layers are formed between the side surfaces of the compression rollers 38a and 38b and the side seals 37, thereby sealing the powder grain introduction/compression part 50.
