The first substrate segment includes a first aerosol former, the second substrate segment includes a second aerosol former different from the first aerosol former, and the second substrate segment is positioned between the first substrate segment and a downstream end of the aerosol source member. The first substrate segment and the second substrate segment are configured such that when heated by a heat source, the first substrate segment is heated to a first temperature and the second substrate segment is heated to a second temperature that is less than the first temperature.

A web of tipping paper and a smoking article manufacturing machine that cuts the web of tipping paper into individual patches and wraps each patch about a respective dual length filter rod to attach a rod of smokable material to opposite ends of each dual length filter rod before the dual length filter rod is cut to form a first and second type of smoking article having first and second filter rod segments, respectively, and in which the first filter rod segment of the first type of smoking article differs from the second filter rod segment of the second type of smoking article, the web of tipping paper including a first lateral portion, and a second lateral portion that differs from the first lateral portion, where the smoking article manufacturing machine is configured to cut the tipping paper web so that each patch is partly formed from the first lateral portion, and partly formed from the second lateral portion, the machine also being configured to wrap the patch about the dual length filter rod such that the part of the patch formed from the first lateral portion is wrapped about a part of the dual length filter rod which, when cut, forms the first filter rod segment, and the part of the patch formed from the second lateral portion is wrapped about a part of the dual length filter rod which, when cut, forms the second filter rod segment.

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 metre. 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).

An elongated smoking article is described that comprises a cylindrical smoking body with a combustible material and a hollow bore filter element downstream to the cylindrical smoking body. The hollow bore filter element comprises a first base area facing the smoking body and a second base area opposite the first base area and a hollow bore extending from the first base area to the second base area. The elongated smoking article further comprises a filter membrane that is arranged between the smoking body and the hollow bore filter, that comprises at least one filter aperture aligned with the hollow bore, that is configured for filtering particles emitted by the heated smoking body, that is permeable for vapor emitted by the heated smoking body and has an effective size between 0.5 μm and 1.5 mm.

A non-combustible heating-type smoking article includes: a tobacco part. The tobacco part includes: a tobacco filler; and a wrapper enclosing the tobacco filler. The tobacco part has a hardness of 0.41 to 1.5 N when compressed by a length corresponding to 10% of a diameter of the tobacco part in a diameter direction of the tobacco part. The wrapper is formed by attaching two or more sheets. The wrapper has a tensile strength of 10 to 30 N in a transverse direction crossing an axial direction of the tobacco part.

The present disclosure relates to smoking substitute consumables, including an aerosol-forming article comprising an aerosol-forming substrate and a terminal filter element at a downstream axial end of the article/consumable. The terminal filter element may comprise a hollow bore extending from an upstream axial end of the terminal filter element to a downstream axial end of the terminal filter element. The hollow bore may be off-set from the axial centre of the terminal filter element.

The present disclosure provides an aerosol-forming article comprising an aerosol-forming substrate and an axially adjacent, downstream filter arrangement. In some implementations, the filter arrangement comprises an upstream filter element, an intermediate filter element and a terminal filter element. The upstream and terminal filter elements may be independently selected from a solid filter element and a hollow bore filter element. The intermediate filter element may be a hollow bore filter element having a greater bore diameter than any other hollow bore filter element in the filter arrangement.
