  • Patent number: 11105044
    Abstract: A method of making a molded paper web includes bringing a permeable patterned surface of a patterned cylinder into contact with a nascent web and conveying the nascent web between a transfer surface and the permeable patterned surface over an arc length of the permeable patterned surface. The arc length forms at least a portion of a molding zone. The method also includes applying a vacuum over at least a portion of the arc length. The method further includes transferring the nascent web from the transfer surface to the permeable patterned surface of the patterned cylinder in the molding zone. The vacuum is applied during the transferring of the nascent web from the transfer surface to the permeable patterned surface of the patterned cylinder.

  • Patent number: 9388534
    Abstract: A method of making a belt-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a dewatered web. The dewatered web is applied to a translating transfer surface. The web is belt-creped from the transfer surface utilizing a polymeric creping belt having perforations. The web is creped from the transfer surface and redistributed on the creping belt to form a web including a plurality of fiber-enriched hollow domed regions protruding from an upper surface of the web, the hollow domed regions having sidewalls being formed along at least a leading edge of the web. Connecting regions form a network interconnecting the hollow domed regions. Transition areas include fibers that transition from the connecting regions into the hollow domed regions, by extending upwardly from the connecting regions into the sidewalls of the domed regions. The web is dried to produce the sheet.

  • Patent number: 9017517
    Abstract: A method of making a belt-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer surface moving at a transfer surface speed. The web is belt-creped from the transfer surface utilizing a generally planar polymeric creping belt provided with a plurality of perforations through the belt, the belt-creping step occurring under pressure in a belt creping nip defined between the transfer surface and the creping belt. The belt travels at a belt speed that is slower than the transfer surface speed, and the web is creped from the transfer surface and redistributed on the creping belt to form a web. The web includes hollow domed regions, connecting regions, and transition areas. The web is dried to produce the belt-creped absorbent cellulosic sheet.

  • Patent number: 8968516
    Abstract: A method of making a belt-creped absorbent cellulosic sheet that has an upper surface and a lower surface. A papermaking furnish is compactively dewatered to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer surface. The web is belt creped from the transfer surface at a consistency of from about 30% to about 60% utilizing a generally planar polymeric creping belt having a plurality of perforations. The belt-creping step occurs under pressure in a belt creping nip defined between the transfer surface and the creping belt. The belt is traveling at a belt speed that is slower than the speed of the transfer surface, and the web is creped from the transfer surface and redistributed on the creping belt to form a web.

  • Publication number: 20140103575
    Abstract: An embossing system is provided for embossing at least a portion of a web comprising a first roll and at least a second roll. The first roll and second roll may define a first nip for embossing the web. At least one of the first roll and the second roll has elongated embossing elements extending substantially in the machine direction and optionally at least one of the first and second rolls has elongated embossing elements extending substantially in the cross-machine direction. At least one of the first roll and the second roll may also have perforate embossing elements extending substantially in the cross-machine direction that may or may not be elongated. The embossing elements are capable of imparting one or both of a cube embossing pattern or a perforate emboss on the web. The web may be a cellulosic fibrous web, a portion of which is lignin-rich, high coarseness fiber having generally tubular fiber configuration. In addition, the web may be creped with an undulatory creping blade.
