A device for moving tubular bodies, includes feeding means for feeding a plurality of tubular pieces, each extending along a respective axis of extension, where the feeding means are configured in such a way as to provide a succession of groups of tubular pieces where each group is defined by a predetermined number of tubular pieces positioned in succession along the respective axis of extension and transversely offset therefrom, and at least one translational transfer means configured to move the pieces along the respective axis of extension to juxtapose them and define an ordered succession of pieces. The translational transfer means is provided with at least one housing for containing at least one tubular piece and with blowing means operating inside the housing and configured to produce an air cushion by which the tubular piece is transferred translationally outside the housing along its respective axis of extension.

A smoking article (10) comprises a tobacco rod (12) and a filter (14) connected to the tobacco rod. The filter (14) comprises a flow restrictor (24). The smoking article further comprises a ventilation zone (18) at a location along the filter downstream of the flow restrictor. The diameter of the tobacco rod (12) is from about 5 mm to about 8.5 mm, the tobacco packing density within the tobacco rod is from about 180 mg/cubic centimetre to about 280 mg/cubic centimetre, and the length of the tobacco rod is from about 15 mm to about 45 mm. Further, the tobacco rod (12) is circumscribed by a wrapper (13) having an air permeability of less than about 20 Coresta units, the wrapper being made of a transparent regenerated cellulose film, or cellophane.

An insertable filter unit for insertion into a smoking article filter having a recess, wherein the insertable filter unit includes an outer casing defining a cavity for storing a smoke modifying agent, and wherein the insertable filter unit is arranged to be inserted into the recess of the smoking article filter by a user.

There is provided a tubular element for use in the manufacture of a filter of a smoking article, the tubular element comprising a first and a second layer wound of substantially continuous strips of a cellulose-fibre-based web material. The strips have predetermined thickness (T) and width (W). The web material is coated on a first surface with an activatable polymer and the first surface of the web material in the first layer faces the first surface of the web material in the second layer. An external diameter of the tubular element is substantially uniform over a given length.

A reusable smoking filtration apparatus includes a tip having a tubular shape with a first end and a second end, a freshness plug configured to be coupled to the first end of the tip, and a cross-hair shaped filter configured to be coupled to the second end of the tip.

The present disclosure relates to an aerosol-forming article comprising: an aerosol-forming substrate; and a filter element having a hollow bore extending from the downstream axial end of the substrate to the downstream axial end of the article.

A tip for a smoking article such as a cigar is disclosed. The tip comprises a longitudinally extending element comprising a plurality of bicomponent fibers which define at least one channel extending longitudinally of the element.

An aerosol-generating article is provided, including: a substrate portion containing aerosol-forming substrate; and a hollow tubular filter portion having an inner diameter of between 0.5 millimeters and 2 millimeters, and the aerosol-forming substrate including at least one aerosol-former selected from the group consisting of: polyhydric alcohols, esters of polyhydric alcohols, and aliphatic esters of mono-, di-, or polycarboxylic acids. A system for generating an aerosol is also provided, including an aerosol-generating device including a heating chamber and a heating element; and the aerosol-generating article, the aerosol-generating article being configured to be insertable into the heating chamber.

A smoking article comprises a tobacco rod and a filter connected to the tobacco rod. The filter comprises a first filter segment and a hollow tube segment downstream of the first filter segment. The hollow tube segment defines a cavity at the mouth end of the filter providing an unrestricted flow channel that extends from the downstream end of the first filter segment to the mouth end of the filter. The length of the hollow tube segment is at least about (25) percent and less than about (50) percent of the overall filter length. Further, the smoking article comprises a ventilation zone in communication with the cavity at a location along the hollow tube segment.
