Abstract
A method of making a belt-creped absorbent cellulosic sheet includes compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fiber orientation, applying the nascent web having the apparently random distribution of fiber orientation to a translating transfer surface that is moving at a transfer surface speed, belt-creping the web from the transfer surface at a consistency of from about 30% to about 60% utilizing a patterned creping belt, the belt-creping step occurring under pressure in a belt creping nip defined between the transfer surface and the creping belt, the web being creped from the transfer surface and redistributed on the creping belt to form a web with a reticulum having a plurality of interconnected regions of different local basis weights.
