摘要： 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.

摘要： 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.
