  • Patent number: 7690131
    Abstract: A device for continuous drying of a pulp web, particularly a tissue web, with a drying drum (1) and an air circulating system, where the drying drum (1) has a cylindrical shell (9) designed as a honeycombed body with an annular, flexible transition profile (13) at the edges of the shell and connected to the end covers.
    Type: Grant
    Filed: June 28, 2005
    Date of Patent: April 6, 2010
    Assignee: Andritz AG
    Inventors: Wilhelm Mausser, Gerald Schadler
  • Patent number: 7384511
    Abstract: The invention relates to a device for changing the cloth of a paper machine, particularly a tissue machine, for example a TAD (through-air drying) machine, with a number of deflection rolls (3), (4), (5), (6) and at least one cleaning device (27), (28), (29) for the machine cloth. Levers (9), (20) are provided on either side of the machine cloth (7), where these levers hold at least one deflection roll (3), (4) and can be pivoted from an operating position to a machine cloth changing position. Thus, the time and the number of personnel required to change the machine cloth are reduced substantially.

  • Patent number: 6923400
    Abstract: A process for continuous reeling of a pulp sheet, particularly a paper sheet, where the sheet runs over a reel drum and is later wound on a winding unit. The pressing force in the nip between the horizontal reel and the reel drum being measured without any losses during the entire winding process. This process is implemented by a device having a reel drum and a horizontal reel supported on load-sensing devices.

  • Patent number: 6821390
    Abstract: Apparatus and process for controlling the basis weight cross-profile, the formation, the fiber direction and other quality parameters of a pulp sheet after the headbox in a dewatering plant. The apparatus including at least one suspension feed, at least one distribution device and at least one drainage device for excess suspension from the distribution device, where the distribution device has a distribution chamber and a turbulence-generating chamber made up of a number of pipes adjacent to one another. It is mainly characterized by the two peripheral zones of the headbox, comprising distribution chamber and turbulence-generating chamber, each having a discharge device in the sheet running direction for a partial suspension stream.
