  • Method for minimizing the accumulation of static charges on fibers resulting from fiberization of pulp lap sheets
    Patent number: 4118832
    Abstract: A method for minimizing the accumulation of static charges on fibers resulting from the dry-fiberization of pulp lap sheets includes the steps of: (1) directing a plurality of the pulp lap sheets into a stacked condition; (2) directing the stack of sheets in a downstream direction to a fiberizing device for separating the fibers from the stack; and (3) applying an antistatic chemical to less than all of the sheets in the stack upstream of the fiberizing device.
