A smoking article filter includes a flow restrictor and a cavity downstream of the flow restrictor. The flow restrictor includes an orifice or flow channel for directing smoke into the cavity. The filter is attached to the tobacco rod with tipping paper and includes an air-admissible ventilating zone at a location downstream of the restrictor.

Smoking article with a restrictor

A smoking article filter includes a valved flow restrictor and a cavity downstream of the flow restrictor. The flow restrictor includes an orifice or flow channel for directing smoke into the cavity. The filter is attached to the tobacco rod with tipping paper and includes an air-admissible ventilating zone at a location downstream of the restrictor. The valved restrictor can be used to isolate a sorbent bearing component of the filter from a flavor bearing component.

Smoking article with valved restrictor

A smoking article, which provides lower amounts of total particulate matter in a latter portion of its puff count, includes a cylinder of smoking material, a combustible hollow tube within the cylinder of smoking material, and a heat sink at a downstream end of the hollow tube. The smoking article also includes a filter system attached to the cylinder of smoking material having a sorbent material and at least one downstream segment of filtering material.

Smoking article with improved delivery profile

An apparatus for laminating at least two strips of strip material and forming the laminate into lightweight, thin-walled tubular members that may be used in the construction of non-combustion smoking articles.

Apparatus making thin laminate structures and forming the structures

An apparatus for precision cutting lightweight, thin-walled tubes that includes transfer drums for transporting rough cut, thin-walled tubes from a source of supply past a first inspection station to determine if the tubes are crushed beyond a predetermined amount, a flaring station to flare the tube ends, an aligning station to align the tubes from cutting, and a cutting station to cut the tube into multiple sections. Section drums are provided that have second and third inspection stations to determine if the tubes have been properly cut.
