The forming apparatus comprises a forming device with a tubular element adapted to form continuous tow material into a continuous tubular rod. The forming device comprises a fluid compressor for generating pressurized fluid, the fluid compressor being in fluid connection with the tubular element to provide pressurized fluid to the continuous tubular rod to heat or cool the continuous tubular rod. The forming device further comprises several fluid conduits to provide pressurized fluid from the fluid compressor to several injection sites arranged along the transport path, wherein at least two fluid conduits of the several fluid conduits comprise a pressure control unit including a pressure sensor and a pressure influencer.

The forming apparatus comprises a feed path for continuously feeding a continuous tow material along a transport direction, a forming device connected to a downstream end of the feed path and adapted to form the continuous tow material into a continuous tubular rod. The forming device comprises a tubular element adapted to allow the continuous tow material to pass through the tubular element to form the continuous tubular rod and a steam generator adapted to generate overheated steam. The steam generator is in fluid connection with the tubular element to provide overheated steam to the continuous tow material. The forming device further comprises several fluid conduits to provide overheated steam from the steam generator to several injection sites arranged along a length of the tubular element, wherein at least one fluid conduit of the several fluid conduits comprises a temperature control unit including a temperature sensor and a temperature influencer.

A device for burning smoking material and inhaling the resulting smoke is disclosed. The device can include an truncated conical member formed from a material having an internal elongated cavity extending from an open end to a closed end.

The present invention relates to a filter comprising a nonwoven substrate having a low density and comprising natural fibers and a binder. The filter can be used as a filter for a smoking or vaping article.

The invention relates to a smoking article having a cylindrical shape with a longitudinal axis running through respective base areas of a distal end and a mouth end of the smoking article. The smoking article segments are at least in part wrapped in a circumferential wrapper and arranged subsequently in from the distal to the mouth end as follows: a. a tobacco segment comprising tobacco or tobacco derived smokable material, b. a cooling segment having a first flow path from the tobacco segment to a filter segment, c. the filter segment comprising a second flow path from the cooling segment to the mouth end.

The filter segment comprises a tobacco product including tobacco particles having an average particle size of 30 m and a dispersion medium for dispersing the tobacco particles. The invention also comprises a method for manufacturing such a smoking article.

An aerosol-generating article (10) includes an aerosol forming substrate (20) and a filter (30) downstream of the substrate. The filter comprises filter material comprising filaments having a linear density of about 4 denier or greater. The filter has a resistance to draw of less than 130 mmWG. Preferably, the filter has a resistance to draw of 90 mmWG or less. More preferably, the filter has a resistance to draw of 70 mmWG or less. Preferably, the density of the filter material is about 0.12 g/cm.sup.3 or greater.

The present disclosure provides filter materials adapted for use as a filter element in an aerosol delivery device and methods of forming such filter materials suitable for use as a filter element in such devices. The disclosure provides, in some embodiments, a filter material which includes a plurality of fibers selected from the group consisting of regenerated cellulose, hemp, sisal, esparto, kenaf, jute, flax, wood, reconstituted tobacco, and combinations thereof, wherein the filter material is in the form of a nonwoven sheet or a fibrous tow.

A filter element suitable for use in smoking articles may include: cellulose acetate fibers bonded together using polyhydroxyalkanoate (PHA) surrounding the cellulose acetate fibers, bonded together using PHA on surfaces of the cellulose acetate fibers, and/or bonded together using PHA. A process for producing the filter element suitable for use in the smoking articles may include: embedding a bundle of the cellulose acetate fibers with an aqueous suspension of the PHA to obtain a wet bundle of the cellulose acetate fibers covered by the aqueous suspension; shaping the wet bundle into a continuous elongated element; heating the elongated element to temperature greater than or equal to 140 C. and less than or equal to 180 C. to melt the PHA and to evaporate water from the elongated element; cooling the heated elongated element to obtain crystallization of the PHA; and/or cutting the elongated element into segments.

The present disclosure relates to a flavor delivery article, a cartridge, and/or an aerosol delivery device that includes such flavor delivery article or a component thereof. The flavor delivery article includes a flavor substrate that can be formed of a porous material optionally having a graded porosity across at least a portion thereof. The flavor substrate further includes a flavor material retained thereby. The flavor substrate may be positioned within an outer shell of the flavor delivery article, and the flavor delivery article may be positioned anywhere within an aerosol delivery device (or a mouthpiece or a cartridge of an aerosol delivery device) wherein the flavor substrate retaining the flavor material may be contacted by a gaseous stream, such as a vapor stream and/or aerosol stream formed in the aerosol delivery device so that the flavor material may become entrained in the vapor stream and/or aerosol stream.
