ABSTRACT:
An air press for noncompressively dewatering a wet web to consistency levels not previously thought possible at industrially useful speeds without thermal dewatering. Side seal members are positioned beyond the lateral edges of the wet web and support fabrics. These seals flex into sealing contact with the opposite sealing contact surfaces upon exposure to the presurized fluid of the air press.
