Abstract:
A method for making a cellulosic web, comprising:(a) depositing an aqueous suspension of papermaking fibers between an endless first fabric and an endless second fabric to form a wet web wherein the wet web is sandwiched between the first and second fabrics; (b) dewatering the wet web to a consistency of about 30 percent or greater using a noncompressive dewatering device that is adapted to cause a pressurized fluid at about 5 pounds per square inch gauge or greater to flow substantially through the web due to an integral seal formed with the wet web; (c) pressing the dewatered wet web against the surface of a heated drying cylinder to at least partially dry the dewatered wet web; and, (d) drying the dewatered wet web to a final dryness.
