ABSTRACT:
An uncreped tissue sheet having improved softness results from supplementally dewatering a wet web to a consistency of greater than about 30 percent using noncompressive dewatering techniques prior to a differential speed transfer and subsequent throughdrying. An air press particularly well suited for providing the supplemental noncompressive dewatering incorporates side and/or end seals to minimize escape of pressurized fluid. A creped tissue sheet can be produced with a variety of manufacturing benefits using the air press.
