  • Patent number: 5888347
    Abstract: Uncreped throughdried cellulosic webs having improved smoothness and stretch are produced by transferring a newly formed web from the forming fabric to a slower moving, high fiber support transfer fabric, preferably using a fixed gap or kiss transfer in which the forming fabric and the transfer fabric converge and diverge at the leading edge of the transfer shoe. The web is then transferred to a throughdrying fabric and throughdried to final dryness, producing a web having an improved softness due to increased surface smoothness.

  • Patent number: 5871615
    Abstract: Security paper carries an intricate tactile surface profile pattern which has been imparted to the paper during its manufacture, at a stage after initial de-watering but before final drying, by passing the paper through a nip between a forming surface corresponding to the desired pattern and a backing surface. The tactile pattern is of excellent durability, and its intricacy offers a high degree of security. The tactile pattern is visible when viewed under low angle light, which facilitates verification or authentication of security documents made using the patterned paper.

  • Patent number: 5693403
    Abstract: High sheet count rolls of spot-embossed, soft bathroom tissue suffer from embossing patterns becoming pressed out by the high winding tension necessary to confine the size of the roll to a diameter of about 5 inches. This size is necessary in order for such high sheet count rolls to fit within the bathroom tissue dispensers found in most households. However, by embossing the tissue between a resilient back-up roll and an engraved embossing roll having short male embossing element heights of only from about 0.005 to about 0.035 inch, the tissue sheet becomes simultaneously calendered, which lowers the sheet caliper (as measured under a compressive load). Because of the resulting lower caliper, the embossed sheet can be wound into the required roll size with less tension on the sheet, such that the embossing pattern for tissue sheets within the roll remains well defined.

  • Patent number: 5470434
    Abstract: Decay-resistant paper suitable for the manufacture of a pot for raising and transplanting seedling is the one partly containing decayable portions, which is prepared by heating paper made of a natural fiber, or a fiber blend composed of a natural fiber and a synthetic fiber, and impregnated with a compound capable of crosslinking the paper cellulose, at a temperature causing the reaction of antidecay treatment and at a temperature causing no such reaction in different portions. Such decay-resistant paper partly containing decayable portions can be easily prepared by bringing the above-mentioned paper impregnated with a compound capable of crosslinking the paper cellulose into contact in a single step with a heating apparatus comprising a heating part of a temperature causing the reaction of antidecay treatment and a heating part of a temperature causing no such reaction.

  • 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: 5411636
    Abstract: The internal bulk of a tissue web can be improved during manufacturing of the basesheet by subjecting the tissue web to differential pressure while supported on a coarse fabric at a consistency of about 30 percent or greater. The differential pressure, such as by applying vacuum suction to the underside of the coarse fabric, causes the wet web to deflect into the openings or depressions in the fabric and "pop" back, resulting in a substantial gain in thickness or internal bulk. The method is especially adapted to improve the internal bulk of wet-pressed tissue webs.

  • Patent number: 5383778
    Abstract: A 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: 5382464
    Abstract: The present invention is directed to an embossed ply suitable for use in a multi-ply, embossed paper. The embossed ply has bosses of two different depths wherein the bosses having a greater depth or the "big bosses" alternate with the more shallow bosses or "small bosses". When the embossed ply is used to form a multi-ply paper, the small bosses are arranged in a tip-to-tip relation with bosses in a second embossed ply, while the big bosses of the first ply are positioned to nest between the bosses of the second ply. Furthermore, a method and apparatus for manufacturing the embossed, multi-ply paper is described.

  • Patent number: 5366785
    Abstract: Disclosed is a cellulosic fibrous structure, particularly a consumer product such as toilet tissue, facial tissue or a paper towel. In a first embodiment, extending outwardly from each face of the cellulosic fibrous structure is a plurality of protuberances. The protuberances extend bilaterally outwardly from the plane of the cellulosic fibrous structure in both directions. The bilaterally extending protuberances increase the caliper and texture of the consumer product embodied in the cellulosic fibrous structure. In a second embodiment, the protuberances extend outwardly, and are induced by fluid embossing, rather than mechanical embossing. Also disclosed is a fluid embossing process for making such cellulosic fibrous structures.

  • Patent number: 5316622
    Abstract: A method and apparatus for making an embossed or dimpled combined board is disclosed. The combined board has two outer or facing layers or webs of paperboard which sandwich an embossed or dimpled middle paperboard layer or web. The middle web is embossed by passing it over two apertured vacuum drums. Embossments extending in one direction are vacuum formed on one surface of the middle web by the first vacuum drum, while embossments extending in the opposite direction are formed on the other surface of the middle web by the second vacuum drum. The embossments, i.e., concave and convex impressions, are located in a generally chess board pattern. The vacuum openings or apertures of the second drum are larger (larger average diameter) than those of the first drum, to thereby compensate for diminishing flexibility of the middle web due to drying as it passes sequentially over the first and second vacuum drums.
