  • 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: 5490902
    Abstract: A method and apparatus for embossing paper products, such as paper towels or toilet tissue, in which the tensile strength extending in the machine direction is modified such that after embossing, the tensile strength in the machine direction is more nearly equal to the tensile strength in the cross-machine direction. During embossing, selected portions of the embossed pattern are embossed more deeply to fracture fibers extending in the machine direction, thereby modifying the tensile strength in the machine direction. An improved paper product is thereby formed having a machine direction:cross-machine direction tensile strength ratio which is more closer to 1:1.

  • 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: 5269983
    Abstract: A mated pair resilient and rigid embossing rolls are disclosed for achieving the advantages of conventional rubber to steel embossing, while avoiding the problems of conventional embossing approaches. In particular, a laser can be utilized to form recesses in a resilient roll such that the resilient roll receives protuberances of a rigid male embossing roll when the rolls are placed in contact. By providing recesses on the resilient roll, the pressure or force required for causing the rubber to flow around the protuberances can be significantly decreased as compared to conventional rubber to steel embossing. As a result, wear on the rolls is reduced, and smaller diameter rolls may be utilized, thereby reducing the cost of the embossing equipment. In addition, since less pressure is required to cause the rubber to flow about the protuberances, roll deflection is not a problem, and an embossed pattern can be imparted having a consistent, high degree of definition across the width of a web.

  • Patent number: 5093068
    Abstract: A method is disclosed for the production of a multi-ply sheet product in which separate non-woven fibrous webs are combined into a multi-ply sheet before embossment, embossed as a multi-ply sheet, embossed webs separated from one another and longitudinally displaced relative to one another, and then recombined into an embossed multi-ply sheet with the embossments out of register with one another. Prior to recombining the webs, the embossments on one of said web is smoothed out increasing the absorbency and softness if the web.

  • Patent number: 5091032
    Abstract: A converted product which is particularly high both in bulk and in perceived softness is produced by pre-embossing the plies individually, joining the plies and calendering and again embossing. In another example, the pre-emboss step is omitted.

  • Patent number: 5030081
    Abstract: An apparatus is disclosed for the production of a multi-ply sheet product in which separate non-woven fibrous webs are combined into a multi-ply sheet before embossment, embossed as a multi-ply sheet, the embossed webs separated from one another and longitudinally displaced realtive to one another, and then recombined into an embossed multi-ply sheet with the embossments out of register with one another. The resulting product exhibits enhanced softness and absorbence as compared with similar products comprising simultaneously embossed multi-ply webs.

  • Patent number: 4803032
    Abstract: A method of embossing a sheet of non-woven fibrous web, 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.
