Abstract: The invention relates to a tobacco preparation method, wherein a tobacco material is prepared through at least one extrusion process comprising compressing the material with an increase in pressure and temperature and mechanically processing and abruptly flash drying the material of an extruder outlet, wherein the tobacco material comprises a tobacco lamina material. The invention further relates to a tobacco preparation device comprising a dosing conveyor (2) and an extruder (3) which compresses a tobacco material with an increase in pressure and temperature and mechanically process and abruptly flash dries the material at the extruder outlet, wherein the components (3, 4) are designated as a unit which can be modularly delimited for processing a tobacco material comprising a tobacco lamina material.
Abstract: A method for making a smoking article is described wherein an aerosol generating cartridge is inserted into a sleeve, preferably having a tobacco insulating material.Also described are articles of manufacture having an elongate jacket module with a rod segment and an annular segment. The rod segment has a length of rod of fibrous material. Disposed logitudinally on either side of the rod segment is an annular segment of insulating material.Additionally, articles of manufacture useful for making smoking articles are described having an elongate structure with two or more repeating sections wherein each section preferably has a tobacco-containing spacer segment and mouthend segment.

Abstract: A method and apparatus for manufacturing a rod of tobacco or the like enclosed by a paper strip is described, wherein a paper strip is supported and transported by a garniture tape and tobacco is deposited on the paper strip. The tobacco is compressed into a tobacco core and the paper strip is closed with its longitudinal edges parts around the compressed tobacco core. A channel is formed in the circumference of the tobacco rod during the compressing by means of an entrance finger with a ridge. A second longitudinal edge part of the paper strip is folded into the channel by a folding element and a first longitudinal edge part is subsequently laid over said channel.

Abstract: An extruded, coherent, multistrand, tobacco-containing, generally cylindrical smoking article and a process for making it are disclosed. The smoking article contains a plurality of strands that are adhered to one another so as to form passageways between the strands, the passageways extending generally along the longitude of the smoking article. The configuration of the strands and passageways provides sufficient heat transfer area and/or residence time for the smoke drawn by a smoker to cool to an acceptable level.

Abstract: Circumferentially extending recesses in the peripheral surface of a rotating suction wheel are filled with tobacco shreds which are delivered in the form of a narrow stream by a pneumatic conveyor having a narrow tobacco propelling channel extending radially of the suction wheel and receiving the shreds of the stream in a current of compressed air. The surplus of shreds is removed by the current and/or by a trimming device which is installed in the interior of the pneumatic conveyor, and such surplus is recirculated through the distributor of a cigarette rod making machine and back into the pneumatic conveyor. The batches are used to form the interrupted core of a composite tobacco filler wherein the core is surrounded by a tubular envelope containing a different blend of tobacco.
Abstract: The invention concerns a method for modifying the peripheral conformation of a cigarette, which has an external, heat deformable, wrapper comprising a proportion of thermoplastic fibers or filaments. The method comprises the application of heat to the wrapper. Heat is applied by a heat forming means moved relatively and in contact with the cigarette, in a direction transverse to the longitudinal axis of the cigarette.
