  • Patent number: 5597639
    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.

  • Patent number: 5593545
    Abstract: A method for making uncreped throughdried tissues is disclosed in which the dried tissue sheet is fully supported by a fabric up to the reel. This method eliminates the open draw between the throughdryer and the reel and thereby eliminates sheet breaks normally associated with such open draws. In addition, the machine direction strength of the sheet can be reduced since the added strength is not needed to traverse the open draw normally present in current processes. Reducing the MD strength in turn enables the production of more square, less stiff sheet, which improves the tactile properties of the product.

  • Patent number: 5573638
    Abstract: The invention provides a continuous paperboard sheet adapted to be slit longitudinally into a plurality of continuous paperboard plies, and to improved paperboard plies for forming single-layer, paperboard tubes. The paperboard sheet has a substantially constant width and includes a plurality of thick longitudinal sections and a plurality of thin longitudinal sections. The thick and thin sections are arranged in alternating relation across the width of the paperboard sheet. The sheet is slit longitudinally along the thin sections to provide a plurality of tube-forming paperboard plies.

  • Patent number: 5573830
    Abstract: An embossed tissue having improved bulk and puffiness while being non-nesting by having a lattice pattern and at least two signature bosses. More particularly, one of the signature bosses is defined by embossments having a lower portion which is continuous and an upper portion which is defined by crenels and merlons.

  • Patent number: 5436057
    Abstract: This invention relates to the discovery that the perceived softness of embossed tissue can be increased greatly while avoiding prior art nesting problems if a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike debossments with deeper more sharply defined signature debossments. The stitchlike debossments are rounded and arranged in wavy flowing intersecting lines. The signature debossments are arranged in regions framed by the intersecting wavy flowing lines.

  • Patent number: 4921034
    Abstract: An embossed sanitary paper product and method of making such product. The paper is embossed to form in the paper a midplane and an array of bosses extending up and down from the formed midplane. Each upward extending boss is flanked on two sides, in each of two directions, by a downward extending boss, and in at least one of the two directions, the paper between an upward extending boss tip and an adjacent downward extending boss tip on one side has a higher strain than the paper between the upward extending boss tip and an adjacent downward extending boss tip on the opposite side. The forming of a higher strain region and a lower strain region on opposite sides of a boss can be accomplished by forming asymmetric bosses with each upward extending boss rotated 180.degree. about an axis perpendicular to the plane of the paper with respect to its adjacent downward extending bosses.

  • Patent number: 4440597
    Abstract: High bulk, absorbent paper having a relatively high MD elongation at rupture, and a substantially greater stress/strain modulus in the lowest one-third of its range of MD extensibility--preferably when wet--than equally machine-direction-stretchable, purely dry-foreshortened (e.g., dry-creped) paper having substantially identical MD elongation at rupture. The process includes a differential velocity transfer of a wet-laid embryonic web having relatively low fiber consistency from a carrier to a substantially slower moving, open-mesh transfer fabric having a substantial void volume; and thereafter drying the web while precluding substantial macroscopic rearrangement of the fibers in the plane of the web. The differential velocity transfer is effected without substantial compaction of the web by avoiding substantial mechanical pressing, centrifugal slinging, air blasting, and the like.
