Abstract

An endless belt for use in dewatering of a paper web or sheet is described. The belt has a first surface, an opposite second surface, and a body portion. The body portion is permeable to pressurized gas and substantially impermeable to liquid. The body portion has a first portion adjacent the first surface and a second portion adjacent the second surface. The first portion has a number of air cavities adjacent and exposed to the first surface. The second portion has a number of passageways each of which is dimensioned to be permeable to pressurized gas and substantially impermeable to liquid. Each passageway extends from the second surface to a select one of the air cavities. The belt is used in a press section of a papermaking machine and has the advantage of allowing pressurized gas through the belt into the paper web or sheet while at the same time not acting as a receptor for water expressed in a press nip of the press section.
