The present disclosure provides an aerosol generating component containing a substrate impregnated with one or more aerosol forming materials, the substrate including a cellulosic material substantially free of sulfur compounds, and further including one or more of a tobacco pulp, an aqueous tobacco extract, a filler, and a binder. Further provided is an aerosol delivery device including the aerosol generating component. Such devices utilize electrically generated heat or combustible ignition sources to heat the aerosol forming materials, providing an inhalable substance in the form of an aerosol.

A wrapping device 1 for wrapping a sheet 3 around a group 5 of segments comprises a wrapping conveyor 7 and a contact element 25. The wrapping conveyor 7 comprises a conveyor surface 9 for receiving the group 5 of segments. The contact element 25 provides a counter surface 31. The counter surface 31 is arranged at a distance to the conveyor surface 9 of the wrapping conveyor 7. The counter surface 31 faces the conveyor surface 9 of the wrapping conveyor 7. The counter surface 31 is configured to engage the group 5 of segments and the sheet 3 when the group 5 of segments is moved along the counter surface 31 by the wrapping conveyor 7 to cause rotation of the group 5 of segments to wrap the group 5 of segments with the sheet 3. At least a first portion 41 of the contact element 25 comprising at least a first part 35 of the counter surface 31 is formed by a first material being an elastic material having a shore hardness between 30 A and 70 A.

A composite heat source for use in a smoking article is provided, including a non-combustible porous ceramic matrix; and a particulate combustible fuel embedded within the non-combustible porous ceramic matrix. The non-combustible porous ceramic matrix is formed from one or more particulate materials having a median D50 particle size at least five times less than the median D50 particle size of the particulate combustible fuel. Preferably, the non-combustible porous ceramic matrix includes one or more transition metal oxides.

There is provided an aerosol-generating article including a combustible heat source; an aerosol-forming substrate disposed in thermal communication with the combustible heat source; and a heat-conducting component disposed around at least a portion of the aerosol-forming substrate, the heat-conducting component including an outer surface forming at least part of an outer surface of the aerosol-generating article, wherein at least a portion of the outer surface of the heat-conducting component includes a surface coating and has an emissivity of less than about 0.6. A method of manufacturing the aerosol-generating article is also provided.

A smoking article is provided, having opposed lighting and mouth ends, and including a mouth end portion at the mouth end. A tobacco portion is between the lighting end and the mouth end portion. An aerosol-generation system is between the lighting end and the tobacco portion. The aerosol-generation system includes a heat generation portion, comprising an elongate fluted member actuated by ignition of the lighting end. The fluted member defines grooves extending longitudinally between opposed first and second ends, with the first end being at the lighting end and the grooves being equidistantly spaced apart about the fluted member. Each groove has a maximum depth. The depth maxima of the grooves define a circle having a radius. The maximum depth of each groove is no more than the radius of the circle. A heat generation apparatus for an aerosol-generation system of a smoking article is also provided.
