Abstract
Smoke constituent reduction may be achieved by resolving from puff-to-puff analysis at which location along a tobacco rod production of a particular smoke constituent is maximized, and locally applying an attenuator at such resolved location to reduce production of the constituent. The remainder of the rod is left untreated so as to minimize impact on taste and burn characteristics of the cigarette. The attenuator material may be applied to the cigarette paper using a moving orifice device to create bands of such materials on the cigarette paper at predetermined locations along the tobacco rod.
Description
- Smoke constituent reduction may be achieved by resolving from puff-to-puff analysis at which location along a tobacco rod production of a particular smoke constituent is maximized, and locally applying an attenuator at such resolved location to reduce production of the constituent. The remainder of the rod is left untreated so as to minimize impact on taste and burn characteristics of the cigarette.
- For example, it has been discovered that 40-50% of the formaldehyde found in mainstream tobacco smoke is formed in the first puff. Any one or a combination of cigarette modifications made at the front (lit) end of the tobacco rod will reduce formaldehyde. These modifications include the introduction of an ammonium-source compound, such as ammonium bicarbonate to the tip of the tobacco rod, and the addition of alkali metal salts (fire retardants) such as potassium bicarbonate or potassium phosphate.
- These components may be applied to the cigarette paper using a moving orifice device to create bands of the add-on compound on the cigarette paper. During cigarette making operations, the cigarette rod making machinery includes registration of the compound-containing bands with tobacco rod portions that correspond to the free end portions of the completed cigarettes. The compound-containing band may be approximately 3 to 7 mm wide or possibly wider.
- Novel features and advantages of the present invention in addition to those noted above will become apparent to persons of ordinary skill in the art from a reading of the following detailed description in conjunction with the accompanying drawings wherein similar reference characters refer to similar parts and in which:
-
FIG. 1 is an elevational view of a cigarette produced by the process and apparatus of the present invention; -
FIG. 2 is a perspective view of cigarette paper produced by the process and apparatus of the present invention; -
FIG. 3 is a perspective view of apparatus for producing the cigarette paper shown inFIG. 2 , according to the present invention; -
FIG. 3A is a perspective view of a portion of the perforated belt of the moving orifice slurry applicator shown inFIG. 3 ; and -
FIG. 4 is a diagrammatic view showing the production of the cigarette shown inFIG. 1 , according to the present invention. - Referring in more particularity to the drawings, a preferred method of manufacturing a
cigarette 10 begins with the manufacture of abobbin 12 ofbanded paper 14 comprising a continuous ribbon ofbase web material 16 together with a plurality of spaced-apart transverse regions (or bands) of add-onmaterial 18 comprising the desired attenuator material. Thebase web material 16 is typically a flax or wood pulp fiber mat of basis weight and permeability typical of those used in commercially offered cigarettes. - Preferably, the
bobbins 12 are constructed in accordance with processes and apparatus described in commonly assigned U.S. Pat. Nos. 5,534,114 and 5,997,691, which patents are hereby incorporated by reference in their entireties. - In a preferred embodiment,
pulp slurry 20 is deposited upon a Fourdrinierwire 22 of apaper making machine 24 to form thebase web 16. At a location along the Fourdinierwire 22, preferably downstream of the wet-line of the wire, additional (add-on)material 18 is deposited upon thebase web 16 in the form of tansverse (cross-directional stripes) utilizing a movingorifice slurry applicator 26 which is supported in a fixed relation across thewire 22 at a angle to the moving direction of the wire. Preferably, theslurry applicator 26 comprises an elongate, open-bottom slurry box 28, an endless,perforated belt 30 which passes along the underside of box 28, asystem 32 for supplying add-on material (slurry) to the slurry box and adrive arrangement 34 operative to move the belt along its endless path. Preferably, thebelt 30 includes a row of equally spaced apartholes 36 and the endless belt is driven at a predetermined fixed speed, such that, because of the angle of the slurry box 28, the speed of thewire 22 and the speed of thebelt 30, a plurality of orthogonal spaced apartbanded regions 18 are generated upon thebase web 16. Subsequently thebase web 16, together with thebanded regions 18 are dried, rolled-up, and slit into bobbins, preferably utilizing drying and slitting techniques commonly practiced in the art of manufacturing cigarette paper. - A further aspect of the manufacture of
cigarette 10 is modification of a typicalcigarette making machine 50 comprising agarniture 52, apaper feed system 54 for feeding a ribbon ofpaper 14 to the garniture, atobacco feed system 56 for establishing and feeding a column oftobacco 58 toward thegarniture 52 and acutter 60 downstream of the garniture. Downstream ofgarniture 52, acontinuous tobacco rod 62 is formed and cut at thecutter 60 into two-uptobacco rods 64. Preferably, thecigarette maker 50 of the present invention further includes asensor 70, a data processing (controller)unit 72 and a “lag-lead”mechanism 74 operative upon thepaper 14 as it is being fed into thegarniture 52 of thecigarette maker 50, such that operation of thecutter 60 is always in desired registry (relation) with thebanded regions 18. Preferably, thesensor 70 is configured in accordance with the teachings of commonly assigned U.S. Pat. No. 6,020,969, which patent is hereby incorporated by reference in its entirety. - More particularly, in the preferred embodiment of the present invention, the
sensor 70 is configured to generate a signal indicative of the passing of eachbanded region 18 by the sensor, which signal is communicated to thecontroller unit 72, along with another signal from acutter phase detector 76 which is indicative of the operational phase relationship of thecutter 60. Thecontroller unit 72 is programmed to process these signals to generate an output signal to the lag-lead mechanism 74 to maintain proper relation of thebanded regions 18 relative to thecutter 60 as thecontinuous tobacco rod 62 enters thecutter 60. - Preferably the lag-
lead mechanism 74 is a displaceable roller that is displaceable responsively to signals received from the controller, which in a first or “retracted” position, tends to add an incremental amount of length to the path of thepaper 14 so as to retard (cause an incremental amount of lag) the arrival of banded regions to thecutter 60 so that a desired registration of cutter operation and the banded regions is maintained. Alternatively, in a second or “extended” position, themechanism 74 may effect an incremental shortening of the path of thepaper 14 so as to cause an incremental amount of lead (advancement) in the arrival of thebanded regions 18 at thecutter 60. - In the alternative, the
sensor 70 might be located between thegarniture 52 and thecutter 60 and be operative upon thecontinuous tobacco rod 62. Furthermore, in this embodiment, the lag-lead adjustment mechanism is preferably operative instead upon operation of the cutter so as to maintain the desired phase relationship between the cutter operation and the arrival ofbanded regions 18 at thecutter 60. - Additionally, in another embodiment, the output of the
controller 72 is communicated to a servo drive unit 80 of thegarniture belt 82 to maintain operational registration of thecutter 60 to the arrival ofbanded regions 18 at the cutter. If the controller resolves a drift (advance or lag) away from optimal registry, the servo drive 80 is operated as a lag-lead mechanism to make an intermittent compensatory adjustment in the speed of the garniture belt for a brief duration, immediately after which, the garniture belt is returned to its steady state operational speed. Compensatory adjustment of the garniture belt may be used in combination with the lag-lead mechanism 74 or as an alternative to that mechanism.
