Abstract:
A method for fiberizing a bale of pulp into dry fluff and metering the dry fluff to an airlaid process, the method comprising the steps of:providing a bale of pulp having a density greater than 0.5 g cmâˆ’3; conveying the bale of pulp to a support member, the support member defining an opening through which disrupting elements protrude from below the support member; moving the bale of pulp back and forth over the opening at an adjustable frequency using a reciprocation assembly so that the disrupting elements, which extend outwardly from a disrupting-element support member attached to a rotating shaft, contact a surface layer in the bale of pulp to form dry fluff; selecting a frequency so that the mass of dry fluff formed per unit time corresponds to the mass of dry fluff required by the airlaid process per unit time; and conducting the mass of dry fluff formed per unit time to the airlaid process.
