发明名称 WET PRESSED PAPER WEB AND METHOD OF MAKING THE SAME
摘要 The present disclosure provides a wet pressed paper web (120B, 120C). The web has a first relatively high density region (1083) having a first thickness K, a second relatively low density region (1084) having a second thickness P, which is a local maximum, and a third region (1074) extending intermediate the first and second regions. The third region (1074) includes a transition region (1073) having a third thickness T, which is a local minimum. The present disclosure also provides a method of making a wet pressed web. An embryonic web (120) of papermaking fibers is formed on a foraminous forming member (11), and transferred to a foraminous imprinting member (219) to deflect a portion of the papermaking fibers in the embryonic web (120) into deflection conduits (230) in the imprinting member (219). The intermediate web (120A) and the imprinting member (219) are then pressed between first and second dewatering felts (320, 360) in a compression nip (300) to further deflect the papermaking fibers into the deflection conduit (230) in the imprinting member (219) and to remove water from both sides of the web (120A). The imprinting member (219) can have a continuous, monoplanar web contacting surface (220) for molding a wet paper web (120A, 120B) to have a continuous, relatively high density network (1083) and a plurality of relatively low density, discrete domes (1084) dispersed through the relatively high density network.
