<p>The present invention provides method for making a wet pressed paper web. An embryonic web (120A) of papermaking fibers is formed on a foraminous forming member (11), and transferred to an imprinting member (219) to deflect a portion of the papermaking fibers in the embryonic web into deflection conduits in the imprinting member. The web (120A) and the imprinting member (219) are then pressed between first (320) and second (360) dewatering felts in a compression nip (300) 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 compression nip (300) has an extended length, and can comprise convex and concave opposed compression surfaces.</p> |
