Abstract:
A method for making a cellulosic web, comprising:(a) depositing an aqueous suspension of papermaking fibers onto an endless first fabric to form a wet web; (b) dewatering the wet web to a consistency of about 10 percent to about 30 percent; (c) transferring the wet web to an endless second fabric; (d) sandwiching the wet web between the second fabric and a support fabric and dewatering the wet web to a consistency of greater than 30 percent 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; (e) pressing the dewatered wet web against the surface of a heated drying cylinder to at least partially dry the wet web; and, (f) drying the dewatered wet web to a final dryness.
