  • Patent number: 5034100
    Abstract: A stationary drainage device for a papermaking machine is described including a drainage box which may have a plurality of vacuum chambers and a stationary curved cover formed by cover strips of ceramic material separated by drainage slots. The cover includes a central cover strip of greater width than the other cover strips on opposite sides thereof. A pressure roll presses the paper sheet and the porous conveyor transporting such sheet across the curved cover of the drainage device, against the curved upper surface of the central cover strip at a nip position spaced from the drainage slots and the other cover strips for greater dewatering efficiency. The stationary drainage device may be mounted at the output of the forming section as a stationary couch device or in the press section as a felt conveyor cleaning and dewatering device.
