Abstract: A method of making a fibrous sheet including bringing a permeable patterned surface of a patterned cylinder into contact with a nascent web and conveying the nascent web between a transfer surface and the permeable patterned surface over an arc length of the permeable patterned surface. The arc length forms at least a portion of a molding zone. The method also includes applying a vacuum over at least a portion of the arc length. The method further includes transferring the nascent web from the transfer surface to the permeable patterned surface of the patterned cylinder in the molding zone. The vacuum is applied during the transferring of the nascent web from the transfer surface to the permeable patterned surface of the patterned cylinder.

Abstract: An absorbent cellulosic sheet made by a method that includes forming an aqueous cellulosic web on a portion of a structuring fabric in a papermaking machine, and drying the cellulosic web to form the absorbent cellulosic sheet. The portion of the structuring fabric on which the cellulosic web is formed has a planar volumetric index of at least about 26. The absorbent cellulosic sheet has a caliper of at least about 160 mils/8 sheets and a dry machine direction (MD) to cross machine direction (CD) tensile ratio of less than about 1.0.
