ABSTRACT:
A press structure for performing a dewatering operation in the steps of formation of a traveling fibrous web such as in a paper making machine wherein the wet web is carried on one or more water absorbing felts through a press formed of a pair of extremely tough liquid impervious belts with the belts backed throughout a pressing zone by a series of fluid pressure chambers applying hydraulic pressures to the back of the belt. The chambers are arranged so that a first fluid pressure is applied at a first portion of the pressing zone, and subsequently a second higher pressure is applied to the belts at a second portion of the pressing zone and thereafter a third pressure is applied at a third portion. Each successive pressure is higher than the previous one so that the hydraulic resistance pressure of the moisture leaving the web does not build up at such a rate so as to disrupt the web fibers.
