ABSTRACT:
Improved system for controlling the forming and dewatering of a web of paper by submerged drainage in which air does not penetrate the fiber/aqueous dispersion and the formed web. The dewatering is via altering the natural tension of the meniscus of the water to induce enhanced drainage of water from the aqueous dispersion of paper making fibers in the wetter end of the system and from the drier end of the fabric. Also, the improved horizontal system provides substantially equivalent side surfaces to the paper formed in such system.
