Abstract
A method of making a belt-creped absorbent cellulosic sheet. The method includes compactively dewatering a papermaking furnish to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer. The web from the transfer surface is belt-creped at a consistency of from about 30% to about 60%, utilizing a generally planar polymeric creping belt having a plurality of perforations. The belt-creping step occurs under pressure in a belt creping nip defined between the transfer surface and the creping belt. The belt travels at a belt speed that is slower than the speed of the transfer surface, and the web is creped from the transfer surface and redistributed on the creping belt to form a web having a plurality of interconnected regions of different local basis weights.
