A bandcast tobacco sheet for use in a cigarette includes from about 5 to 15% by weight of wood pulp, from about 15 to 40% by weight of binder and from about 15 to 40% by weight of tobacco. A humectant may be included up to 30% by weight and an additive, such as menthol, may be added to up about 30% by weight. A bandcast tobacco sheet is used in elongated strips along the outer surface of a tobacco rod between the tobacco rod and an inner surface of an outer wrap of cigarette paper.

Process for making a bandcast tobacco sheet and smoking article therefrom

A cigarette with burn rate modification is described. The cigarette has a partial double wrap design and incorporates an inner wrap material which extends partially around the interior portion of the outer wrapper of a cigarette. The inner wrap can be a single element or can be a plurality of strips which extend coaxially along the tobacco column and which affect the burn rate of the cigarette. The partial inner wrap material exhibits a low porosity and forms zones of high diffusion and low diffusion along the length of the tobacco rod. These zones may be singular or may be alternating and are coaxial. The low diffusion zones are aligned with the inner wrap material.

Cigarette with burn rate modification

A cigarette making machine for manufacturing of a cigarette with burn rate modification is described. The cigarette maker allows for mounting of a special bobbin of material which is different in size and width of a normal wrapper bobbin and feeds both the outer wrap web of material and narrower inner wrap web of material to the garniture. A slitting device may be utilized to cut the inner wrap web of material into a plurality of individual strips which are placed adjacent the outer wrap web of material in the garniture area of the maker. The inner wrap web of material may derive from a transverse wound bobbin in order to store large linear amounts of inner wrap web material.

Apparatus for making cigarette with burn rate modification

The invention relates to a coaxial smoking article, particularly a coaxial cigarette, comprising a coaxial rod of smokable material, which rod has an inner segment (,) of smokable material surrounded by a covering (,), around which covering is an outer segment (,) of combustible or thermally destructible/decomposable material, which outer segment is also surrounded by a covering (,). The combustible or thermally destructible/decomposable material of the outer segment contains no or only a very small proportion of spot-forming substances. Further, the coverings of the inner and outer segments are such that spot-forming substances in the inner segment are essentially unable to reach the outside of the covering. Hence, a cigarette having reduced potential for the production of spotting is so formed.
