An object insertion unit is configured to introduce a plurality of objects into engagement with the rod member along the longitudinal axis. A dispensing device is configured to selectively dispense a liquid substance into the filter material, substantially commensurately with the introduction of the plurality of objects into engagement with the rod member, wherein the liquid substance is configured to affect an attribute associated with the objects. A rod-dividing unit is configured to divide the rod member into a plurality of rod portions such that each rod portion includes at least one object and a portion of the liquid substance.
