Abstract

A method of embossing a sheet of non-woven fibrous web, and the resulting fibrous sheet structure, e.g. toilet tissue, with a series of identical boss elements arranged in a uniform pattern in a manner to avoid nesting of the embossments and resulting non-uniform product rolls when the sheet is rolled onto a mandrel. The embossments are uniformly spaced in rows which in the longitudinal direction form an angle in the range of 15.degree. to 23.degree. relative to the edge of the sheet or roll and an angle in the range of 40.degree. to 57.degree. relative to the cross direction of the sheet or roll.
