Abstract
An apparatus arranged to form a continuous tobacco rod of a smoking article, comprises a conveyor conveying a tobacco material stream in a conveyance direction, and a wrapping material supply arrangement advancing a web of wrapping material in the conveyance direction adjacent to the tobacco material stream. A constriction member receives the tobacco material stream at an inlet end and reduces a cross-sectional area of the tobacco material stream. The reduced-area tobacco material stream exits the constriction member at an exit end, and the wrapping material web wraps about the reduced-area tobacco material stream exiting the exit end. An additive source supplies an additive material to the reduced-area tobacco material stream through a dispensing port disposed about the exit end of the constriction member, prior to the reduced-area tobacco material stream being wrapped by the wrapping material web to form the continuous tobacco rod.
