Abstract
An apparatus for fiberizing bales of pulp into substantially dry fibers and fiber aggregates. One embodiment 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, 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, an adjustable reciprocating assembly permitting adjustment of the frequency by which the transportation assembly moves back and forth over the opening.
