Abstract
The perceived softness of embossed tissue can be increased greatly while avoiding nesting when a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike bosses with deeper more sharply defined signature bosses. The stitchlike bosses can be rounded and arranged in wavy flowing intersecting lines. The signature bosses can be arranged in regions framed by the intersecting wavy flowing lines.

A nonwoven fibrous web having a machine direction and a cross direction, with the machine direction extending substantially parallel to a free edge of the web, and having a plurality of bosses formed therein comprising:
- a pattern which is made up of uniform stitch shaped bosses to form polygonal cells which make up a lattice structure;
- and
- a pattern which is made up of signature bosses which fill at least some of the cells;
- wherein the combination of lattice structure and signature bosses are offset from the machine direction.
A non woven fibrous web having a lattice pattern defined by an array of stitch shaped bosses which have a height, are encompassed by downwardly flaring regions, and form a plurality of polygonal cells, a substantial fraction, less than all, of said polygonal cells having therein a signature boss having a height exceeding that of said stitch shaped bosses and being encompassed by a downwardly flaring region more steeply inclined than the downwardly flaring regions of said stitch shaped bosses.
A sheet of tissue having a plurality of bosses formed therein defining a lattice pattern comprising a plurality of polygonal cells, a fraction, more than one-third, but less than two-thirds, of said polygonal cells having therein a signature boss, said lattice pattern being defined by an array of stitch shaped bosses arranged to form said lattice pattern, wherein said stitch shaped bosses are encompassed by arcuate regions having a cross-sectional radii of curvature exceeding that of said signature boss which has a height exceeding the height of said stitch shaped boss.
A sheet of tissue having a plurality of bosses formed therein defining a lattice pattern having a plurality of polygonal cells, a fraction, more than one-third but less than two-thirds, of said polygonal cells being filled with a signature boss, said lattice pattern having generators and being defined by a sinuous array of stitch shaped bosses undulating about the generators of said lattice pattern, said stitch shaped bosses being encompassed by rotund arcuate regions having cross-sectional radii of curvature exceeding at least about 0.015 inch;
- said signature being comprised of a plurality of elongated bosses having a height of boss exceed the height of boss of said stitch shaped bosses by at least 0.003 inch, said elongate bosses being encompassed by arcuate regions having cross-sectional radii of curvature of not more than 50% of the average radius of curvature of the arcuate regions encompassing said stitch shaped bosses.
A roll of embossed tissue having a plurality of bosses formed therein, said bosses comprising:
- two series of intersecting sinuous lines of stitch shaped bosses, one series of lines being disposed at a first acute angle clockwise of the machine direction of the roll, the other series of lines being disposed at a second acute angle counterclockwise of the machine direction of the roll whereby a repeating pattern comprising an oblique lattice of substantially uniform staggered wavy diamonds is defined;
- a plurality of signature bosses centrally located within alternating rows of said diamond, the disposition of said bosses being configured such that substantial nesting of said signature bossed on said roll occurs at a maximum of two locations on said roll, the outermost of said locations being spaced at least 1/32 inch below the exterior surface of said roll and, the innermost, at least 0.5 inch inward from said outermost substantial nesting location.
A roll of embossed tissue having a plurality of bosses formed therein, said bosses comprising;
- two equally spaced series of intersecting sinuous lines of stitch shaped bosses, one series of lines being disposed at a first acute angle clockwise of the machine direction of the roll, the other series of lines being disposed at a second acute angle counterclockwise of the roll whereby an oblique lattice of substantially uniform staggered wavy diamonds is defined;
- a plurality of signature bosses centrally located within alternating rows of said diamond, the disposition of said bosses being configured such that, adjacent to the surface of said roll, signature bosses on closely adjacent overlapping repeats are displaced from each other by at least 0.50 inch in the machine direction.
