  • Sieve Mechanism For the Production of Paper, and Method For the Treatment of Non-Woven Fibers
    Publication number: 20080196854
    Abstract: To increase the processing speed of a sieve mechanism (9) for extracting carrier liquid from a fiber suspension (39) during the production of paper (27), paperboard, or cardboard, the sieve mechanism (9) is provided with a first electrode (43) which is disposed above, in, or below a sieve region and is connected to a high-voltage surge generator (46). A plasma can be generated in the fiber suspension (39) or in the immediate vicinity thereof, whereby the tensile strength of the paper (27) is also increased.
