The present invention relates to a multicomponent aerosol-forming article defining a longitudinal axis, the article comprising: a first rod-shaped component comprising a first longitudinal surface having a first and a second axially opposed ends, said first longitudinal surface being at least partially wrapped around the longitudinal axis in a first wrapping sheet; a second rod-shaped component comprising a second longitudinal surface having a first and a second axially opposed ends, said second longitudinal surface being at least partially wrapped around the longitudinal axis in a second wrapping sheet, the first end of the second component being in direct abutment to the second end of the first component along said longitudinal axis; wherein a portion of said second longitudinal surface at said first end of said second component is free of said second wrapping sheet; and wherein said first wrapping sheet is wrapped for at least an overlapping length along the longitudinal axis on the second wrapping sheet.

A method of producing smoking articles, the method comprising a first step of providing a continuous array of first filter members (42), second filter segments (20) and tubular members (40). A tubular member (40) is provided between each pair of consecutive first filter members (42) and a second filter segment (20) is provided between each first filter member (42) and each tubular member (40). Each second filter segment (20) contains one or more breakable capsules, wherein each breakable capsule comprises an outer shell and an inner core containing an additive. The continuous array of first filter members (42), second filter segments (20) and tubular members (40) is then wrapped with a continuous sheet of plug wrap (44) to form a wrapped filter array, wherein the plug wrap (44) has a basis weight of less than 90 grams per square meter. The wrapped filter array is cut at an intermediate position along each first filter member (42) to provide multiple filter rods, each filter rod comprising two first filter segments (18), a tubular member (40) positioned between the first filter segments (18) and a second filter segment (20) provided between each first filter segment (18) and the tubular member (40). Next, a tobacco rod (12) is provided in axial alignment with and adjacent to each first filter segment (18) of one of the filter rods, and the filter rod and a portion of each tobacco rod (12) are wrapped in a tipping wrapper (50). Finally, the tipping wrapper (50) and the filter rod are cut at an intermediate position along the length of the tubular member (40) to form multiple smoking articles (10), each smoking article (10) comprising a tobacco rod (12) connected to a filter (14), wherein each filter (14) comprises a first filter segment (18) downstream of the tobacco rod (12), a second filter segment (20) downstream of the first filter segment (18), and a hollow tube segment (22) positioned between the second filter segment (20) and the mouth end of the filter (14). The hollow tube segment (22) defines a cavity (24) at the mouth end of the filter (14).

A smoking article includes a smokable material and a filter downstream of the smokable material. The filter includes activated carbon material having a BET of between 1000 and 2000 m.sup.2/g and exhibiting less particle breakthrough than granulated coconut shell derived activated carbon currently used for filters of smoking articles.

There is provided an aerosol generating article (10) comprising an aerosol generating substrate (12), a mouthpiece (14) in axial alignment with the aerosol generating substrate (12), and a tipping wrapper (20) wrapped around the mouthpiece (14) and at least a portion of the aerosol generating substrate (12).
