Abstract: The present invention discloses an improved paperboard for use in food or non-food products. The disclosed board utilizes a novel method of applying adsorptive material to packaging paperboard to overcome emissions (by adsorption thereof) of odiferous manufacturing components from the board, as well as any offensive odors emitted by contents of packages made from the board. The disclosed approach utilizes known adsorptive materials, which are applied to the pulp stock in such a manner that it does not negatively impact either the appearance or physical attributes of the finished board.

Abstract: Quickly exchangeable inserts for sheet feeding vacuum cups are provided to accommodate an extended range of sheet permeability. Projecting form structure inserted within a feed cup bellows provides a surface discontinuity for the vacuum nozzle to retard and inhibit double sheet feeding of either highly permeable or highly impermeable paper. Single sheet feed reliability is thereby improved.
