Abstract
A process for making a paper sheet is disclosed. After a web is transferred from a forming wire to a papermaking belt preferably having deflection conduits, the web is overlaid with a flexible sheet of material such that the web is disposed intermediate the sheet of material and the papermaking belt. The sheet of material has an air permeability less than the papermaking belt, and is preferably air-impermeable. An application of a fluid pressure differential to the sheet of material causes deflection of at least a portion of the sheet of material towards the papermaking belt and, preferably, deflection of at least a portion of the web into the conduits of the papermaking belt and water removal from the web through the conduits of the papermaking belt.
