Abstract
A method of making a fibrous sheet. The method includes forming a nascent web from an aqueous solution of papermaking fibers, dewatering the nascent web to form a dewatered web having a consistency from about ten percent solids to about seventy percent solids, moving the dewatered web on a transfer surface, and transferring the dewatered web from the transfer surface to a molding roll at a molding zone. The molding roll includes an exterior and a patterned surface on the exterior of the molding roll. Papermaking fibers of the dewatered web are redistributed on the patterned surface in order to form a molded paper web. The method also includes transferring the molded paper web to a drying section and drying the molded paper web in the drying section to form a fibrous sheet.
