  • Particulate addition method and apparatus
    Patent number: 6709613
    Abstract: A nonwoven web contains an even distribution of its composite materials by the separate application of particulate material such as superabsorbent particles into a forming head outside the air stream for deposition of thermoplastic fibers in the forming head. The thermoplastic fibers are distributed by air entertainment through tubular forming screens having rotary distribution members therein. The particulate absorbents are generally placed in the forming box by distribution units which may have metering devices and outlet chutes extending into the forming head.
    Type: Grant
    Filed: December 21, 2001
    Date of Patent: March 23, 2004

  • Method and apparatus for applying a material to a web
    Patent number: 5997691
    Abstract: A method and apparatus of manufacturing a web which is striped with add-on material, comprising: a first arrangement which establishes a sheet of base web from a first slurry and moves the established sheet along a first path; a second arrangement for preparing a second slurry; a moving orifice applicator operative so as to repetitively discharge the second slurry upon the moving sheet of base web, the moving orifice applicator comprising: a chamber box arranged to establish a reservoir of the second slurry across the first path; an endless belt having an orifice, the endless belt received through the chamber box; a drive arrangement operative upon the endless belt to continuously move the orifice along an endless path and repetitively through the chamber box, the orifice when communicated with the reservoir being operative to discharge the second slurry from the reservoir through the orifice; a flow distribution system for introducing the second slurry into the chamber box at spaced-apart feed locations alon
