Latest Patents
One of Soderlund's latest patents is titled "Method and apparatus for zoned application of particles in fibrous." This invention involves an apparatus and method for effecting zoned deposition of superabsorbent particles in a fibrous web. It utilizes dual dispensing nozzles to create selected deposition patterns, with fluidized streams of superabsorbent particles formed through rotary valve assemblies that enable pulsed flow to each nozzle. The length, width, and relative positioning of the deposition patterns can be selectively varied to meet desired performance characteristics.
Another significant patent is the "Method and apparatus for manufacture of a diaper with elastic margins." This invention outlines a method for creating a diaper that features one or more elastic margins. The diaper employs an elastomeric material for the entire moisture-permeable backing sheet, which is heat unstable and relatively inelastic in its unshrunk form but becomes stable and elastic when heat shrunk. The method allows for the maintenance of longitudinal tension in the central portion of an end-to-end assembly of diaper units while enabling the edge tension to relax, facilitating the shrinkage of the backing sheet after heating.
