ABSTRACT:
A filter making apparatus includes a positioning device having a passageway therethrough, with the passageway guiding a continuous flavor element such as a continuous strand of textile material from an inlet of the passageway to an outlet of the passageway. A liquid flavorant is introduced into the passageway at a desired flow rate and the strand of material carries the supplied liquid flavorant out of the positioning device at a rate substantially equal to the desired flow rate. A portion of the passageway can form a bath of the liquid flavorant supplied to the passageway through a separate inlet at approximately atmospheric pressure. A portion of the positioning device guides the continuous strand of material through the bath, or guides the strand to pass along the bottom of the passageway, and the saturated or partially saturated strand of material then exits from an outlet of the passageway to a point in the path of filter tow material that is being converged to form a filter rod.
