  • Patent number: 11291242
    Abstract: A system, apparatus and method for forming a smoke filter including a forming nozzle through which a fibrous bundle material passes. The forming nozzle includes a converging passage, at least one first internal cavity in fluid connection with a first working fluid source, and a plurality of first holes fluidly connecting the at least one first internal cavity with a working surface of the forming nozzle. The plurality of first holes are further positioned and directed such that in passing through the plurality of first holes, the first working fluid conveys the fibrous bundle material through the forming nozzle in a transport direction. A guide pin is disposed along a central axis of the converging passage, the guide pin including an elongated body which tapers in the transport direction. A bobbin disposed downstream of the forming nozzle.

  • Publication number: 20200068950
    Abstract: A non-combustible smoking article and method of use thereof may be provided. The non-combustible smoking article may include a composite filter forming an elongated, cylindrical rod. The composite filter may further include a cavity having a nicotine source; an aerosol-forming substrate proximate the nicotine source; and at least one capsule filled with an additive for modifying a characteristic of inhalable vapor. An internal heater may be inserted into at least the nicotine-containing cavity of the composite filter. A peripheral heating source may also be disposed along an exterior length of the composite filter. The internal heater and the peripheral heating source may be activated to heat at least a portion of the composite filter, wherein the heat generates inhalable vapor to be drawn and inhaled by a consumer.
