  • Felt for papermaking machine
    Patent number: 4199401
    Abstract: A felt for use in a papermaking machine includes a surface layer of coarse fibers and an underlayer of relatively fine fibers secured to the surface layer. The surface layer supports a wet paper web as the felt and the web are moved through the press section of the machine. At the exit side of the nip of the press rolls, the water within the felt migrates by capillary action away from the web side to the finer underlayer as the nip pressure at the press section is released. Web rewetting is therefore significantly decreased.
