  • Patent number: 5274930
    Abstract: A method and apparatus for drying of a cellulosic fibrous structure having constant basis weight and/or density or multiple regions varying in basis weight and/or density. Such a cellulosic fibrous structure may have a nonuniform moisture distribution prior to drying by the disclosed method and apparatus. An equally or more uniform moisture distribution is achieved by providing a micropore medium in the air flow path which has a greater flow resistance than the interstices between the fibers in the cellulosic fibrous structure web. The micropore medium is the limiting orifice in the air flow used in the drying process. The micropore medium may be executed in a laminate of plural laminae, each of successively increasing or decreasing pore size. This arrangement provides the advantage that minimal sagging or deformation of each lamina into the next coarser lamina occurs and lateral air flow between the micropore medium and the cellulosic fibrous structure is reduced.

  • Patent number: 5245025
    Abstract: Disclosed herein is a cellulosic fibrous structure having multiple regions distinguished from one another by basis weight. The structure is a paper having an essentially continuous high basis weight network, and discrete regions of low basis weight which circumscribe discrete regions of intermediate basis weight. The cellulosic fibers forming the low basis weight regions may be radially oriented relative to the centers of the regions. The paper may be formed by using a forming belt having zones with different flow resistances. The basis weight of a region of the paper is generally inversely proportional to the flow resistance of the zone of the forming belt, upon which such region was formed. The zones of different flow resistances provide for selectively draining a liquid carrier having suspended cellulosic fibers through the different zones of the forming belt.

  • Patent number: 5213037
    Abstract: This invention relates to an anilox printing apparatus for depositing ink onto a substrate in a predetermined pattern. The apparatus has a reservoir provided with a weir so that ink may continuously overflow the top or end of the weir and be removed from the reservoir in a controlled fashion while maintaining a constant backpressure of ink in the reservoir. This arrangement provides the advantage that ink leakage and splashing caused by debris entering the nip associated with a doctor blade held against the anilox roll or by surface imperfections interfering with the seal formed by such a doctor blade are eliminated. This also provides a printing apparatus for complete coating of the periphery of the anilox roll with ink without a high pressure system.

  • Patent number: 5171236
    Abstract: A disposable absorbent article, such as a diaper. The disposable absorbent article has a topsheet foreshortened relative to the backsheet. This foreshortening creates a void space between the topsheet and the backsheet. Fecal material is communicated through an aperture in the topsheet to the void space.At least two longitudinally oriented spacers are disposed in the void space to keep the void space open under the weight of the wearer's body. While the void space is open, fecal material communicated through the aperture can be transported towards the rear waistband without interuption significant obstruction, preferably isolating the fecal material from the skin of the wearer. This isolation provides for easier cleaning of the wearer when the disposable absorbent article is soiled and removed.

  • Patent number: 5149334
    Abstract: Absorbent articles such as diapers or sanitary napkins incorporating particulate, absorbent, polymeric compositions comprising interparticle crosslinked aggregates. The interparticle crosslinked aggregates comprise precursor particles of substantially water-insoluble, absorbent, hydrogel-forming, polymer material; and an interparticle crosslinking agent reacted with the polymer material of the precursor particles to form crosslink bonds between the precursor particles. The polymeric compositions of the present invention may be incorporated into absorbent articles as the sole absorbent material; as an absorbent core comprising a mixture of fiber material and discrete particles of the polymeric composition; or as a laminate (a layered absorbent core) containing such polymeric compositions. The performance of absorbent articles is enhanced by the use of such polymeric compositions due to the high rate of fluid uptake and minimal gel blocking properties of the interparticle crosslinked aggregates.
