Abstract: In a filter cigarette having a tobacco strand, a wrapping and a filter, the filter possesses at least one gas phase-active filter part which contains at least one gas phase-reducing substance. The gas phase-reducing substances are embedded in a filter material matrix. They are introduced in a quantity of at least 75 mg per filter and at least 5 mg/mm of the length of the gas phase-active filter part. The filter cigarette exhibits a filter ventilation of at most 30% (or of from 30% to 70%). The NFDPM value is between 4 and 10 mg/cigarette (or in the range of from 2 to 4 mg/Cigarette), as measured in accordance with ISO smoking conditions. The gas phase quotient Q1, defined as (?g of benzene per cigarette)/(mg of CO per cigarette) and measured in accordance with ISO smoking conditions, is less than 1.5, preferably less than 1.

Abstract: In a process of manufacturing smokeless tobacco articles on a rod-making device, an endless tobacco web (1a), the filler web, is shaped into an endless rod (1b), preferably by use of a funnel-like formatting device (4). Another endless web (5a), the wrapper web, is provided as a wrapper and wrapped around the endless rod (1b). The endless wrapped rod is cut into individual cylindrical portions (11).

Abstract: A smoking article includes a tobacco rod and a wrapper, wherein the wrapper includes at least one zone treated with an inorganic salt providing reduced ignition propensity. Preferably, the porosity of the wrapper in the treated zones is larger than 10 CU. Suitable inorganic salts are, e.g., magnesium chloride, aluminum sulfate, alum, sodium tetraborate, the hydrated forms of these compounds, sodium chloride, or mixtures thereof.

Abstract: The invention relates to a process for enhancing the filling capacity of tobacco, such as cut tobacco leaf or tobacco midribs, or tobacco additional material, by treating the tobacco material having an initial moisture of 10-30% with a treatment gas consisting of nitrogen and/or argon at pressures of 400 to 1,000 bar followed by a continuous decompression and subsequent thermal post-treatment of the discharged tobacco material. The filling density of the tobacco charge in the autoclave is greater than 0.2 kg/dm3.

Abstract: The invention relates to a process for the improvement of the filling capacity of tobacco such as shredded tobacco leaves or ribs by treatment of the tobacco material having up to approx. 30 wt.-% initial moisture with a treatment gas composed of nitrogen and/or argon at pressures of 50 to 1,000 bar under continuous or stepped compression, followed by a continuous or stepped decompression, the compression and decompression steps taking place in either one autoclave or in cascade-like sequence in several autoclaves, and by subsequent thermal aftertreatment of the discharged tobacco material, which is characterized in that the thermal aftertreatment is carried out with a flowing heat-transferring medium of a mixture of permanent gases and superheated water vapour, wherein the proportion of permanent gas is kept constant at a value in the range from 10 to 60 vol.-%.

Abstract: The invention relates to a method for improving the fillability of tobacco, as tobacco leaves or ribs and/or tobacco additives, by treatment of the tobacco material, which has approx. up to 15 wt. % initial moisture with a treatment gas consisting of nitrogen and/or argon at pressures of 50 to 1,000 bar with continuous or graduated compression followed by continuous or graduated decompression, with the compression and decompression stages taking place in either one autoclave or with cascade-type switching in several autoclaves, followed by thermal after-treatment of the tobacco material discharged, which is characterised in that the compression is carried out at an operating temperature above 55° C., preferably at 60 to 90° C. and the initial moisture of the tobacco material lies within the range 8 to 14 wt. %.
