<p>A method of producing a low flame propagation cigarette wherein, even if the lighted cigarette is left on a combustible material, the self-extinguishing action of a combustion adjusting agent or the removal of heat of combustion by the combustible material prevents scorching from occurring in the combustible material or from advancing so much as in the past; and a device for producing a low flame propagation cigarette. The device of producing a low flame propagation cigarette comprises a combustion adjusting agent applied region forming unit (30, 30') for forming combustion adjusting agent applied regions in a plurality of longitudinally or peripherally spaced positions in a wrapping paper web (20a) being conveyed on a wrapping paper conveyer unit (18), a unit (14) for feeding cut tobacco to the wrapping paper having been formed with the combustion adjusting agent applied regions, a wrapping tube unit (23) for wrapping the wrapping paper having cut tobacco fed thereto into a cigarette form, and a cigarette cutting unit (28) for cutting the wrapping paper wrapped into a cigarette form into lengths corresponding to the length of a cigarette.</p> |
