Description

[0001]
Background of the Invention The position along the tobacco rod where the production of a specific smoking component is maximized is determined by a puff-to-puff analysis method, and the ate is determined at the determined position. By applying a nuator locally, the amount of smoking components produced can be reduced. The rest of the tobacco rod is left untreated to minimize its effect on the taste and burning characteristics of the cigarette.
[0002]
SUMMARY OF THE INVENTION It has been discovered that 40-50% of the formaldehyde found, for example, in mainstream smoke of tobacco is formed in the initial puff. Formaldehyde is reduced by any one or combination of cigarette modifications made to the front (lit) end of the tobacco rod. These improvements include introducing an ammonium source compound such as ammonium bicarbonate to the tip of the tobacco rod and adding an alkali metal salt (flame retardant) such as potassium bicarbonate or potassium phosphate.
[0003]
These components can be applied to cigarette paper using a moving orifice device to create a band of the impregnating compound on the cigarette paper. During the cigarette manufacturing operation, the cigarette rod maker aligns the compound-containing band with the tobacco rod portion corresponding to the free end portion of the finished cigarette. The compound-containing band is about 3-7 mm wide and may be wider.

DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings in more detail, a more preferred method of manufacturing a cigarette 10 comprises a plurality of laterally spaced regions (i.e., an impregnating material comprising a desired attenuator material). It begins by producing a bobbin 12 of banded paper 14 comprising a continuous ribbon of base web material 16 with a band 18). The base web material 16 is a mat of base weight and permeable flax or wood pulp fibers typical of the base web materials used in commercially available cigarettes.
[0006]
The bobbin 12 is preferably made by the method and apparatus described in U.S. Pat. Nos. 5,534,114 and 5,997,691 to the same owner. These patents are incorporated by reference in their entirety.
[0007]
In one preferred embodiment, the pulp slurry 20 is placed on a fourdrinier 22 of a paper machine 24 to produce the base web 16. Preferably, an additional material (impregnated material) 18 is fixedly supported across the fourdrinier at an angle to the direction of travel of the fourdrinier, preferably along the fourdrinier downstream of the wet line of the fourdrinier 22. The moving orifice slurry applicator 26 is deposited on the base web 16 in a lateral (cross-directional stripe) configuration utilizing a moving orifice slurry applicator 26. The slurry applicator 26 preferably has an elongated, open bottomed slurry box 28, an endless perforated belt 30 passing along the underside of the box 28, and supplies impregnated material (slurry) to the slurry box. It includes a system 32 and a drive 34 that operates to move the belt along its endless path. The belt 30 preferably has a row of equally spaced holes 36 and the endless belt is driven at a predetermined fixed speed so that the angle of the slurry box 28, the fourdrinier Depending on the speed of the belt 22 and the speed of the belt 30, a plurality of band regions 18 are formed on the base web 16 and are spaced at right angles. Subsequently, the base web 16 is dried, rolled up and then cut into bobbins, together with the band areas 18, preferably using the drying and cutting methods commonly practiced in the art of cigarette paper making.
[0008]
Another aspect of the manufacture of the cigarette 10 is a garniture 52, a paper supply system 54 for supplying a ribbon of paper 14 to the garniture, a tobacco supply system 56 for producing a column 58 of tobacco and supplying it to the garniture 52 and a garniture. Of a typical cigarette making machine 50 with a cutter 60 downstream of the cigarette. Downstream of the garniture 52, a continuous tobacco rod 62 is formed and then cut with a cutter 60 into a two-up tobacco rod 64. Preferably, the cigarette maker 50 of the present invention further includes a "delay" which operates on the paper 70 when the sensor 70, data processing (control) unit 72, and paper 14 are being fed into the garniture 52 of the cigarette maker 50. A "lag-lead" mechanism 74 is provided so that the operation of cutter 60 is always in the desired alignment with band area 18. Preferably, the sensor 70 is arranged in accordance with the teachings of U.S. Pat. This patent is incorporated herein in its entirety.
[0009]
More specifically, in a preferred embodiment of the present invention, sensor 70 includes a cutter phase detector, which emits a signal indicating that each band region 18 is passing, the signal being indicative of the operating phase relationship of cutter 60. It is arranged to be transmitted to the control unit 72 together with another signal from 76. The controller 72 processes these signals and issues an output signal to the lag-advance mechanism 74 to maintain the proper relationship of the band region 18 to the cutter 60 as the continuous tobacco rod 62 enters the cutter 60. Be programmed.
[0010]
The lag-advance mechanism 74 is preferably a movable roller that can move in response to a signal received from the controller, the roller reaching the cutter 60 in the first or "retracted" condition. To delay (increase the magnitude of the delay), the path length of the paper 14 is increased to try to maintain the desired alignment of cutter operation and band area. Alternatively, in the second or “extended” state, the lag-advance mechanism 74 can shorten the path of the paper 14 to increase the advance (advance) of the arrival of the band area 18 at the cutter 60. .
[0011]
Alternatively, sensor 70 can be positioned between garniture 52 and cutter 60 and actuated on continuous tobacco rod 62. Further, in this embodiment, the lag-advance adjustment mechanism preferably operates when the cutter is actuated to maintain the desired phase relationship between actuation of the cutter and the arrival of the band region 18 at the cutter 60. .
[0012]
Further, in another embodiment, the output of controller 72 is communicated to servo drive unit 80 of garniture belt 82 to maintain operative alignment of cutter 60 with the arrival of band area 18 at the cutter. When the controller resolves the deviation (lead or lag) from the optimal match, the servo drive unit 80 operates as a lag lead mechanism to intermittently compensate and adjust the garniture belt speed in a short time, Immediately, the garniture belt returns to its steady state operating speed. Garniture belt compensation adjustment can be utilized in combination with or instead of the lag-advance mechanism 74.
