  • Patent number: 6592721
    Abstract: An air delivery device is provided for dewatering a suction roll in a paper machine by applying pressurized air to expel residual water or debris outwardly from through-holes. The air delivery device is positioned at a suitable circumferential position of the suction roll to prevent water carryover back to the suction box location. In one preferred embodiment, an internal blowbox is mounted near the inner surface of the suction roll for blowing out water from the suction roll holes to augment the natural centrifugal forces. The blowbox can be used as a standalone dewatering unit, or in conjunction with an external doctor blade or wipe. In another preferred embodiment, at least one air knife, air pipe or air shower is used for dewatering. In another preferred embodiment, at least one interior stationary air foil is used to generate a pressure pulse which creates outward air flow through the through-holes.

  • Publication number: 20030056919
    Abstract: A method of cleaning a semipermeable membrane, the semipermeable membrane being configured for carrying a fiber web, includes the steps of providing a cleaning fluid and applying the cleaning fluid on the semipermeable membrane. Further, an air press configured for carrying the semipermeable membrane therethrough is provided, and the air press has pressurized air therein. The semipermeable membrane is conveyed through the air press and is subjected to the pressurized air within the air press. The pressurized air thereby flushes the cleaning fluid through the semipermeable membrane.

  • Patent number: 6524443
    Abstract: A paper machine includes a traveling belt for carrying a fiber web, and a cutting device disposed below the belt for cutting the fiber web into smaller pieces. The cutting device has an inlet and an outlet. A guiding device guides the fiber web from the belt to the inlet of the cutting device. A pulper is connected with the outlet of the cutting device for receiving the smaller pieces of fiber web from the cutting device. The traveling belt may be in the form of, e.g., a wire, felt or water impervious belt. The cutting device may be in the form of, e.g., a shredder, fluffer, water jet cutter, laser cutter and/or roll cutter.

  • Patent number: 6502434
    Abstract: A washer for washing a fiber suspension includes a porous surface traveling in a running direction and having a width in a direction transverse to the running direction. The porous surface is configured for carrying the fiber suspension thereon. A shower includes a pipe extending parallel to the width of the porous surface. The pipe has a sidewall with a longitudinally extending slot therein. The shower further includes a pair of lips connected to the pipe. The lips are positioned immediately adjacent to and on opposite sides of the slot, thereby defining a slot nozzle with a discharge gap. The lips are movable toward and away from each other to adjust the size of the discharge gap.

  • Publication number: 20020166647
    Abstract: A method and apparatus for incorporating feature substances into a still moist but already sufficiently consolidated paper web provides for directing a feature substance suspension onto the surface of the paper web as a laminar jet with low jet pressure. A special pressure control circuit ensures that the jet pressure is always constant regardless of the number of parallel feature substance suspension jets directed onto the paper web. This makes it possible to incorporate a great variety of line codings in paper under the same process conditions without any visible changes in fiber structure occurring in the paper.

  • Patent number: 6468397
    Abstract: A system and process for removing unwanted fibers from a forming fabric during a wet papermaking process is disclosed. The system includes a scarfing shower configured to emit a cleaning fluid that contacts the forming fabric. In particular, the cleaning fluid tangentially contacts the forming fabric while the forming fabric is being guided around a turning roll. Preferably, the cleaning fluid is emitted in a direction that is opposite to the direction at which the forming fabric is moving.

  • Publication number: 20020092637
    Abstract: An apparatus (62) and method for supporting a web (22) of paper being transferred through a region (40) from the surface (26) of one moving component (24) of a papermachine (20) to the surface (30) of a subsequent moving component (28) of the papermachine utilizes an air-permeable sheet (70) and a blowbox (86) or Coanda air knives (38) supported adjacent the air-permeable sheet. The sheet is supportable in a stationary condition across so as to span at least a portion of the papermachine region through which the moving web of paper is transferred and adjacent one side (72) of the web, and the blowbox or Coanda air knives are used to move air away from the side (72) of the air-permeable sheet opposite the web so that as the web is moved through the papermachine region, the web is biased by atmospheric air pressure into contact with the air-permeable sheet and moves in sliding engagement therealong.
