  • Patent number: 5338408
    Abstract: In a Fourdrinier paper making system where all of the water from the stock slurry is removed in one direction downwardly through the paper web, a sheet forming unit, including two spaced dandy rolls with a pocket roll inbetween, is added to press a secondary fabric downwardly on the top surface of the paper web. The pocket roll cooperates with a suction box below the paper web to remove water while the web passes over a low vacuum section and then over a high vacuum section and then over a low vacuum section of the suction box. This treatment produces a better internal bond between the fibers in the paper web and also produces better surface properties.
