  • US 6,171,447 B1 discloses a papermaking belt having the features of the preamble of claim 1.
  • absorbent tissue products are frequently embossed in a subsequent operation after their manufacture on the paper machine, while the dried tissue web has a low moisture content, to impart consumer preferred visually appealing textures or decorative lines.
  • absorbent tissue products having both desirable physical properties and pleasing visual appearances often require two manufacturing steps on two separate machines.
  • Such a method can produce a dried tissue web having a non-uniform basis weight in the localized areas or regions arranged in a systematic manner to form the texture. While such a method can produce textures, the sacrifice in the uniformity of the dried tissue web's physical properties such as tear, burst, absorbency, and density can degrade the dried tissue web's performance while in use.

  • the present invention relates to a sculpted fabric for the manufacture of a tissue web, as set forth in claim 1.
  • the present Invention relates to a method for manufacturing a tissue product, as set forth in claim 37.
  • the background texture regions are designed to impart preferred finished product properties when used as an UCTAD throughdrying fabric, including roll bulk, stack bulk, CD stretch, drape, and durability.

  • decorative pattern refers to any non-random repeating design, figure, or motif. It is not necessary that the curvilinear decorative elements form recognizable shapes, and a repeating design of the curvilinear decorative elements is considered to constitute a decorative pattern.
  • machine-direction refers to the direction of travel of the fabric, the fabric's individual strands, or the paper web while moving through the paper machine.
  • cross-machine direction refers to a direction orthogonal to the machine-direction extending across the width of the paper machine.
  • the strands may be arranged at acute angles to the MD and CD directions.
  • plane difference refers to the z-direction height difference between an elevated region and the highest immediately adjacent depressed region.
  • Z-direction refers to the axis mutually orthogonal to the machine direction and cross-machine direction.
  • transfer fabric is a fabric that is positioned between the forming section and the drying section of the web manufacturing process.
  • transition region Is defined as the intersection of three or more floats on three or more consecutive MD strands.
  • the transition regions are formed by deliberate interruptions In the textured background regions, which may result from a variety of arrangements of intersections of the floats.

  • a set of first raised elements 108' in a first background region 38 interacts with a set of second raised elements 108" in a second background region 128 to define a transition region 62 between the first and second background regions 38 and 50, wherein both the discontinuity or shift In the pattern across the transition region 62 as well as a change in surface topography along the transition region 62 contribute to a distinctive visual appearance in the wet tissue web 15 molded against the composite sculpted fabric 100, wherein the loci of transition regions 62 define a visible pattern in the molded wet tissue web 15 (not shown).
  • first and second raised elements 108' and 108" overlap slightly and define a nonlinear transition region 62 (i.e., there is a slight curve to it as depicted).
  • parallel, adjacent raised elements 108 in either a first or second background region 38 or 50 are spaced apart in the cross-machine direction 118 by a distance S slightly greater than the width W of a first or second raised element 108' or 108" (e.g., the cross-machine direction spacing from centerline to centerline of the first and second raised elements 108' and 108" divided by the width W of the first and second raised elements 108' and 108" can be greater than about 1, such as from about 1.2 to about 5, or from about 1.3 to about 4, or from about 1.5 to about 3.
  • the spacing S is nearly the same as the width W (e.g., the ratio S/W can be less than about 1.2, such as about 1.1 or less or about 1.05 or less).
  • the overlapping first and second raised elements 108' and 108" in the transition region 62 results in a gap width of about -2W or less (meaning that the ends 122 and beginnings 124 of the first and second raised elements 108' and 108" overlap by a distance of about twice or more the width W of the first and second raised elements 108' and 108").
  • the tapered raised elements 108 are depicted which are otherwise similar to the raised elements 108 as shown in FIGURE 3 .
  • first background region 38 comprising cured resin first raised elements 108' having a shape and dimensions ( W, L, H , and S , for example) different from those of the second raised elements 108" of the second background region 50 .
  • the raised elements 108 need not be straight, as generally depicted in the previous figures, but may be curvilinear.
