  • Patent number: 10385516
    Abstract: The disclosure provides tissue webs and products comprising cross-linked cellulosic fibers. In certain embodiments cross-linked cellulosic fibers are selectively disposed in one or more layers of a multi-layered tissue, wherein the tissue layer comprising cross-linked fibers is adjacent to a layer which is substantially free from cross-linked fiber. The cross-linked fibers may include hardwood kraft fibers reacted with a cross-linking agent selected from the group consisting of DMDHU, DMDHEU, DMU, DHEU, DMEU, and DMeDHEU. Tissue products and webs produced in this manner generally have improved sheet bulk, without losses in strength, compared to similar tissue products produced without cross-linked cellulosic fibers. As such the tissue products of the present invention generally have a basis weight from about 10 to about 50 gsm, a sheet bulk greater from about 8.0 to about 12.0 cc/g and geometric mean tensile from about 730 to about 1,500 g/3?.

  • Patent number: 7699959
    Abstract: Tissues are provided as multi-ply tissue products having greater tactile sensation and resiliency in hand. Improved tissues may have a thickened and reduced density middle layer. The tissues may serve as applicators for chemical agents to be released during use of the tissue. A tissue having an improved tactile impression to the consumer, with enhanced resilience and high external bulk is disclosed. In one embodiment, a multi-ply structure having at least three plies is desirable. A middle or intermediate ply is comprised an increased thickness and a greater bulk is employed. In general, the exterior plies of the tissue are smooth and desirable to the consumer.

  • Patent number: 7608165
    Abstract: A multi-layer web formation section has at least two successive wire units (300, 310). First and second headboxes (100, 110) supply pulp suspension jets to the forward end of the first wire unit (300) and the second wire unit respectively to form a first partial web (W1) and a second partial web (W2) which are joined at a joint (N1) between the second wire unit (310) and a bottom wire (11). A first non-pulsating dewatering zone (Z1b) in the forward end of a two-wire stretch of the second wire unit (310) is formed by a fixed formation shoe (200b) having a curved cap (201) placed against one side, having openings with an under-pressure applied. A two-wire stretch of the second wire unit (310) has a second pulsating dewatering zone (Z2b), formed by fixed dewatering lists (210b) in the cross machine direction with gaps (220b) therebetween with an under-pressure (Pb) applied.

  • Patent number: 7524404
    Abstract: An apparatus for producing an embossed product including a first embossing member having a plurality of discrete embossing elements disposed in a first non-random pattern having at least one first single pattern unit. The total area of the distal ends of the discrete embossing elements in the first single pattern unit is less than about 5.0 cm2. The apparatus also includes a second embossing member having a plurality of linear embossing elements disposed in a second non-random pattern having at least one second single pattern unit. The total area of the second distal ends in the second single pattern unit is less than about 10 cm2. The second non-random pattern is coordinated with the first non-random pattern such that when engaged with each other the first single pattern unit and the second single pattern unit make up an embossing pattern single pattern unit.

  • Publication number: 20080295984
    Abstract: The invention comprises a method for producing identification marks (5) on layer-structured paper or board (7) to be manufactured in a continuous web and the marked papers and boards obtained with this method. With this method, the marks (5) are made with a laser beam on a moving web form fiber layer (1), on which a second layer of material (6) is subsequently overlaid in such a way that the marks remain inside the layer-structure of the moving web. The second material layer (6) may comprise a second fiber layer or, for example, a polymer coating. The laser marking could take place, for example, by burning the surface of the fiber layer (1) or by engraving it. Inside the layer structure, the marks (5) are protected, but detectable with a detector to ensure the authenticity of the material. The marked paper or board is suitable for product packages to be protected against product forgeries.

  • Patent number: 7435313
    Abstract: The present invention relates to an apparatus for producing a deep-nested embossed paper product comprising two embossing cylinders, each cylinder having a plurality of protrusions on its surface. The protrusions on each cylinder are disposed in a non-random pattern where the respective non-random patterns are coordinated to each other. The two embossing cylinders are aligned such that the respective coordinated non-random pattern of protrusions nest together such that the protrusions engage each other to a depth of greater than about 1.016 mm. The protrusions each comprise a top plane and sidewalls, with the top plane and sidewalls meeting at a protrusion corner. The protrusion corners of the protrusions of the embossing cylinders of the apparatus of the present invention have a radius of curvature ranging from about 0.076 mm to about 1.778 mm.

  • Patent number: 7387702
    Abstract: Paper or paperboard laminate composed of at least one bulk-promoting layer, here termed bulk layer (1), 40-98% of which is composed of cellulose fibers with a freeness value of 550-950 ml CSF, and on at least one side of the bulk layer at least one secondary layer (3a, 3b?), which has a greater density than the bulk layer, the secondary layer and bulk layer being joined indirectly to one another over basically the whole of their opposing surfaces and the laminate having a bending stiffness index greater than 2.5 Nm7/kg3, but less than 14 Nm7/kg3, calculated as a geometric mean value for machine direction and cross direction. According to the invention a thin intermediate layer (2a), which has a higher drainage resistance than the bulk layer and has been formed together with the bulk layer, is arranged between the said bulk layer (1) and secondary layer (3a, 3b?).
