Method and apparatus for forming a batt of particulate material for use as a component in an absorbent core assembly
Abstract:
A method and apparatus for forming a wad of particulate material which may be used in an absorbent article. The apparatus may include a laydown drum having a plurality of vacuum zones, a plurality of fence zones, and a plurality of blow-off zones. The plurality of vacuum zones may be substantially permeable to permit vacuum air to pass through and into the laydown drum. The plurality of fence zones may be substantially impermeable to inhibit air to pass through. The plurality of blow-off zones may be substantially permeable to permit blown air to pass out of and through said laydown drum. The apparatus may also include a deposition chute for depositing particulate material on a web of material in close proximity to the laydown drum. A shield may also be attached to the deposition chute.
