  • Patent number: 9523173
    Abstract: A press apparatus is disclosed for removing water from a web that has been supported on an upstream forming wire. The press apparatus includes a first roll which cooperates with the forming wire for transferring the web from the forming wire to the first roll, the first roll being a suction roll. A second roll is disposed downstream relative to the first roll, the second roll cooperating with the first roll for defining therebetween a first nip for the removal of a first portion of the water from the web during passage of the web through the first nip. The second roll is a suction roll. A third roll is disposed downstream relative to the second roll, the third roll cooperating with the second roll for defining therebetween a second nip for the removal of a second portion of the water from the web during passage of the web through the second nip. The third roll is a plain roll.

  • Patent number: 8557085
    Abstract: In a papermaking machine, a dryer apparatus for drying a web. The dryer apparatus includes a drying cylinder and an upstream roll cooperating with a peripheral surface of the drying cylinder. A looped felt extends around the upstream roll and is guided by the upstream roll so that the looped felt and the peripheral surface of the drying cylinder define therebetween a nip for the passage therethrough of the web. The looped felt moves away from the peripheral surface of the drying cylinder downstream relative to the nip such that the web inherently follows and is supported by the peripheral surface of the drying cylinder downstream relative to the nip. A shoe press is disposed downstream relative to the nip, the shoe press including a looped press felt and a shoe which cooperates with the peripheral surface of the drying cylinder downstream relative to the nip.

  • Patent number: 7811419
    Abstract: A press apparatus (10) is disclosed for removing water from a web (W). The apparatus includes a rotatable roll (12) which defines a peripheral surface (14). An elongate shoe (16) has a curved surface (18) which cooperates with the peripheral surface (14) of the roll (12) for defining therebetween a nip (N) for the passage therethrough of the web (W). The arrangement is such that when the web (W) extends through the nip (N), water is pressed from the web (W). A blanket (20) is disposed between the curved surface (18) of the shoe (16) and the web (W) for supporting the web (W) during the passage of the web through the nip (N), the blanket (20) enclosing the shoe (16). Moreover, the blanket (20) has a diameter within a range 500 mm to 875 mm.

  • Patent number: 6886456
    Abstract: In an enclosed shoe press having a press blanket extending through an extended nip defined between a backing roll and a press shoe, an anchor device is disclosed for anchoring a peripheral edge of the press blanket. The anchor device includes a rotatable head which defines a conical peripheral surface for supporting the blanket. A ring defines a concave surface which cooperates with the conical surface of the rotatable head such that the peripheral edge of the blanket is anchored between the conical surface of the head and the concave surface of the ring. Also, a pin extends radially inwardly from the ring, the pin engaging a hole defined by the peripheral edge of the blanket. Additionally, a plurality of barbs extend away from the concave surface for assisting in anchoring the peripheral edge of the blanket against the conical surface of the rotatable head.
