Abstract: A method of making a belt-creped absorbent cellulosic sheet. A paper making furnish is compactively dewatered to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer surface that is moving at a transfer surface speed. The web is belt-creped from the transfer surface at a consistency of from about 30% to about 60% utilizing a generally planar polymeric creping belt having a plurality of perforations, 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. 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. The web is then dried.

Abstract: A method of making a fabric-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a nascent web having an apparently random distribution of papermaking fiber. The dewatered web is applied to a translating transfer surface. The web is fabric-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric, under pressure, in a fabric creping nip defined between the transfer surface and the creping fabric.

The web is creped from the transfer surface and redistributed on the creping fabric to form a web with a drawable reticulum having a plurality of interconnected regions of different local basis weights. The web is dried and the web is drawn. The step of drawing the web preferentially attenuates the fiber-enriched regions of the web.
