  • Patent number: 11744278
    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.

  • Patent number: 6913023
    Abstract: A filter attaching apparatus comprises a drum 20 for conveying an intermediate product of a filter cigarette and a receiving drum 36 for feeding a tip paper piece, and winds the tip paper piece around the intermediate product while rotating these drums with the tip paper piece adhered to the intermediate product. Suction chambers 48 and 50 are disposed in the vicinity of the drum 20 that conveys the intermediate product, and suction openings of the suction chambers extend in a conveying direction of the intermediate product along an outer periphery of the drum 20. Fine particles of shredded tobacco and the like that are scattered by rotation of the drum 20 are sucked through the suction openings into the suction chambers 48 and 50 and the like, so that the intermediate product is completely isolated from an atmosphere of the fine particles of the shredded tobacco and the like.
