A system including an aerosol-generating device and the aerosol-generating article is also provided.

A filter component for tobacco smoking, comprises a filter body (1), a filter core material (2), and a filter closing layer (3). The filter body (1) is a hollow cylinder, and the filter core material (2) is built in the filter body (1). At least one end of the filter body (1) is closed by the filter closing layer (3). The filter core material (2) is a granular filter material, filament filter material, folded filter material, or similar filter material having a shape structure with a large specific surface area. The filter component for smoking can be widely used in the field of tobacco and can be built into cigarettes or arranged in related accessories. The filter component for smoking can effectively filter moisture and tar in smoke, and can also ensure good smoking feel and effect.

Smoking article include a smokable material and an activated carbon particle downstream of the smokable material. The activated carbon particle is produced from a whole seed. The activated carbon particle has a length, width and height. At least two of the length width and height are independently in a range from about 1 mm to about 7.5 mm. The particles can be spheroids, in which case the length, width and height would be the same or similar.

Tips and filters fabricated of sheets of paper like material or other suitable materials that have adhesive strategically located on at least a portion of both sides of the sheets of tips and filters papers for hand-rolling and machine rolling cigarettes. Tips and filters rolled from such sheets adhere onto itself in a manner that maintains users desired diameter and adhere to rolling papers securing tip filter inside rolled cigarette. and adhesive also on the outside of the tip filters of rolled cigarettes.

An apparatus and processes for producing compound cigarette filters by horizontally assembling multiple filter segments onto the horizontally oriented transverse flutes of a continuous belt. Spaced apart hoppers are serially arranged above the belt, and each hopper contains at least one of the multiple segments of the compound filter being assembled. A transfer structure between each hopper and the belt serially delivers the filter segments to the flutes on the belt, and after such assembly the various filter segments are removed as a group from each flute of the continuous belt. The filter segments are then combined as a group with wrapped tobacco rods to thereby produce filtered cigarettes.

The invention relates to a method for introducing elongated objects defining a longitudinal axis into a continuous flow of material, the method comprising the steps of: —providing a reservoir for holding the elongated objects to be introduced into the continuous flow of material; —introducing the elongated objects from the reservoir into a transfer chamber that is arranged such that the objects are aligned therein with their longitudinal axis parallel to each other; —moving the elongated objects along a direction parallel to their longitudinal axis in a single line path from the transfer chamber to a delivery channel by a rotatable wheel, the rotatable wheel arranged adjacent the transfer chamber and adapted to move the elongated objects located in the transfer chamber by contacting the elongated objects with a peripheral surface of the rotatable wheel; —inserting the elongated objects from the delivery channel to a location where the elongated objects are to be introduced into the continuous flow of material; and —regulating an insertion speed of insertion of the elongated object from the delivery channel to a location where the elongated objects are to be introduced into the continuous flow of material on the basis of a speed of the continuous flow of material at the location in which the elongated object is to be introduced.

The invention relates to a filter manufacturing apparatus including: —a feed path adapted to continuously feed a filter material along a longitudinal transport direction; —a forming device connected to a terminating end of the feed path and adapted to form the filter material into a rod-shaped continuous filter body and deliver the formed continuous filter body, the forming device including: a tubular element adapted to allow the filter material to pass therethrough to form the filter material into the continuous filter body; a heat source adapted to heat the filter material passing in the tubular element; —a diameter measuring device positioned at the outlet of the forming device and adapted to measure a diameter of the continuous filter body.

Cigarettes are provided which contain a filtering system and flavorants encapsulated with polyvinyl acetate, wherein deactivation of a sorbent by the flavorant is reduced through the encapsulation of the flavorant within the polyvinyl acetate. A preferred flavorant is menthol. The encapsulated flavorants are prepared by mixing at least one flavorant with polyvinyl acetate and a solvent, such as ethanol, and forming the encapsulated flavorants. Methods of making cigarettes and smoking the articles are also provided.
