Abstract
The present invention provides method for making a wet pressed paper web. An embryonic web of papermaking fibers is formed on a foraminous forming member, and transferred to an imprinting member to deflect a portion of the papermaking fibers in the embryonic web into deflection conduits in the imprinting member. The web and the imprinting member are then pressed between first and second dewatering felts in a compression nip to further deflect the papermaking fibers into the deflection conduits in the imprinting member and to remove water from both sides of the web. The first felt is positioned adjacent a first surface of the web. The imprinting member is positioned between the second surface of the web and the second felt. The second felt has an air permeability which can be greater than that of the first felt.
