Paper sheets, such as creped tissue sheets used for converting into tissue products such as facial tissue and bath tissue, can be softened with by passing the sheets through one or more fixed-gap noncompactive straining nips formed between two engraved rolls having partially-engaged small straining elements of a shape which strains the sheet in all directions. The straining treatment substantially reduces the rigidity of the tissue sheet by increasing the internal bulk without substantially reducing the tensile strength. The method provides a means for making a throughdried-like tissue sheet from a wet-pressed tissue sheet.
