Abstract
The present invention is directed to a method and apparatus for fiberizing bales of pulp into substantially dry fibers and fiber aggregates, i.e., dry fluff, and metering the resulting dry fluff to a receptacle or other process, such as an airlaid process for making disposable absorbent articles. One version of an apparatus having features of the present invention includes: a bale support member for supporting a bale of pulp, the bale support member defining two openings; two rotatable fiberizing assemblies having disrupting elements protruding through the openings an adjustable distance above the bale support member to contact a surface layer of the bale of pulp, the surface layer having a dimension parallel to the longitudinal axis of the fiberizing assembly, each disrupting element extending longitudinally and substantially continuously along the fiberizing assembly for a distance of 100% or more of said surface-layer dimension; a transportation assembly for moving the bale of pulp back and forth along the bale support member and over the openings so that the disrupting elements contact a surface layer in the bale to form substantially dry, individual fibers and fiber aggregates…
