  • Concentricity stabilizer which is both a structural coupling and an alignment device
    Patent number: 6283669
    Abstract: A novel concentricity stabilizer acts as both a structural coupling and an alignment device and a means for providing a concentric structure from a series of segmental modules. The concentricity stabilizer creates a self support system that permits construction of the individual modular pocket assemblies into a perfectly circular drum ready for attachment to suitable drum flanges or discs and shaft assemblies.

  • Apparatus for forming controlled density fibrous pads for diapers and the other absorbent products
    Patent number: 6098249
    Abstract: The present invention provides an improved apparatus for forming a fibrous pad for absorbent products with improved density control. Fibers entrained in a high speed air flow are deposited onto the foraminous surface of a spaced, three-dimensional pad-forming pocket. The fine foraminous pad forming screen is supported on its periphery by two top plates, a coarse forming screen, two subplates and end rails which incorporate a device to hold the pad forming screen.A gas flow regulating system consisting of precisely placed cross directional fixed and adjustable airflow control louvers controls the air flow direction and reduces spill over and turbulence during the pad formation and especially during the transition of the forming pocket into and out of the air stream as the rotary former shell rotates through the filling position.

  • Inlet and outlet plenum apparatus for uniform delivery of fiber to a pad former
    Patent number: 5983457
    Abstract: The present invention provides an inlet and outlet plenum apparatus for improving the forming of fibrous pads for absorbent products and providing improved density control. Fibers entrained in a high speed air flow coming from a fiberizer or other fiber source enter an inlet plenum which reduces velocity by increasing the area of the inlet plenum in a linear manner thereby decreasing turbulence and improving the density distribution of the fiber deposited onto the foraminous surface of a pad-former screen. The outlet plenum allows for a controlled velocity increase which reduces under-screen turbulence and further improves fiber distribution and density control.
