Definitions
- the present invention relates to a cigarette paper which imparts self-extinguishing properties to a cigarette made therefrom and which has at least one discrete perforated area.
- a test to determine the level of inflammation of cigarettes is described in ASTM E2187-04b.
- the test consists of placing a smoldering cigarette on a pad consisting of 10 layers of filter paper. The test is carried out on 40 cigarettes and the percentage of cigarette which is extinguished on the substrate before the gluten cone reaches the beginning of the cigarette filter is determined.
- the self-extinguishing property can be understood, for example, to mean that at least the majority of the cigarette tested according to ASTM E2187-04b fulfills the mentioned criterion, ie. H. the percentage is above 50%.
- a typical cigarette is made of tobacco, which is wrapped by the cigarette paper and together with it forms a typically cylindrical tobacco rod.
- the tobacco rod is followed by the filter, which typically consists of cellulose acetate fibers.
- the filter and tobacco rod are wrapped by the tipping paper.
- the tipping paper bonds the filter to the tobacco rod.
- Self-extinguishing a cigarette is achieved in most cases by appropriate design of the cigarette paper, so the paper that covers the tobacco.
- the cigarette paper is designed so that, at least in areas of the cigarette paper, the diffusion constant is so low that not enough oxygen is added to the cone to keep the glowing process going. As a result, the smoldering cigarette goes out.
- Cigarette papers are made from cellulose fibers derived from wood, flax or other materials. Mixtures of cellulose fibers of various origins are also used. Cigarette papers have a typical basis weight of 10 g / m 2 to 60 g / m 2 , with the range of 20 g / m 2 to 35 g / m 2 being generally preferred.
- Cigarette papers also often include inorganic mineral fillers added to the paper at 10% to 40% by mass.
- a frequently used filler is lime (calcium carbonate), but also other oxides and carbonates, such as magnesium oxide and aluminum hydroxide.
- the cigarette paper may also be provided with burn salts which increase or decrease the smoldering speed of the paper.
- burn salts which increase or decrease the smoldering speed of the paper.
- very often used are sodium and tripotassium citrate and mixtures thereof, which are added to the paper to 0% to 5% of the paper pulp.
- the group of fire salts of industrial importance additionally includes citrates, malays, tartrates, acetates, nitrates, succinates, fumarates, gluconates, glycates, lactates, oxylates, salicylates, ⁇ -hydroxycaprylates and phosphates.
- Cigarette papers are typically made into rolls of, for example, between 0.3m and 5m widths and cut into reels having a cigarette circumference derived width, typically 9mm to 35mm.
- This perforation can be done by various methods.
- the electrostatic perforation is used, in which the paper is conveyed through one or more spark gaps, which burn holes in the paper. These holes typically have a diameter between 5 ⁇ and 100 ⁇ .
- the laser perforation can be used, which produces slightly larger holes with typical diameters between 50 ⁇ and 500 ⁇ .
- the mechanical perforation may also be used, in which holes are produced in the paper by needling or similar tools. These holes have a typical diameter between 100 ⁇ and 2000 ⁇ .
- the air permeability achieved in the perforation processes can be very high, for example up to more than 6000 CU, but cigarette papers are usually perforated so that the air permeability after perforation is between 50 CU and 500 CU.
- the perforation process can be carried out after papermaking on separate dedicated perforating machines in roll or bobbin width.
- a perforation on the cigarette machine so before, during or after the production of cigarettes or similar tobacco articles from the cigarette paper on the cigarette machine after any perforation possible.
- the full-surface perforation of a cigarette paper with a low outlet air permeability brings a significant disadvantage in the acceptance of a cigarette made from this paper by the smoker with it. Due to the high air permeability flows much dilution air when smoking in the cigarette. During smoking, the tobacco rod and thus the perforated cigarette paper are consumed.
- One way to compensate for this effect is not to choose the air permeability over the length of the tobacco rod constant, but to give such a continuous profile through the perforation of the cigarette paper of the air permeability along the axis of the cigarette, that the increase in the smoke values from train to train Train is reduced as possible. On the cigarette paper web, therefore, a repetitive, continuous air permeability profile is to be produced by perforation.
- the endless tobacco rod formed from the cigarette paper must be cut at the very beginning and end of such a continuous air permeability profile so that the air permeability profile is in the right place on the finished cigarette.
- the detection of the beginning of the profile is because of the continuous course of the air permeability but, if at all, then very imprecisely possible.
- the present invention is therefore based on the object to overcome the disadvantages of the prior art.

- the starting paper has a basis weight of 10 g / m 2 to 60 g / m 2 , preferably from 20 g / m 2 to 35 g / m 2 .
- the object of the present invention is further achieved by a use of a cigarette paper according to the present invention for the production of a cigarette according to the present invention.
- the present invention is based on the surprising discovery that it is not necessary to produce a continuous air permeability profile, but that it is already sufficient to perforate a discrete area with a constant air permeability located close to the filter on the cigarette paper to achieve a comparably good effect.
- the average air permeability in the mouth half closer to the mouthpiece or third is preferably higher than in the remaining part of the cigarette paper.
- a discrete perforated area lying near the cigarette filter is now located in a region of the tobacco rod in which, during smoking, the pressure difference between the environment and the interior of the tobacco rod is high, ie comparatively much air in the tobacco rod Tobacco strand can flow. In areas closer to the ember cone and farther from the mouth end, this pressure difference is smaller. Thus, these areas contribute less to the amount of air flowing into the cigarette, and it affects the Abrauch tone little in a row, if these areas are not perforated, so have a low air permeability.
- the perforated areas are now of a discrete nature and clearly demarcated from non-perforated areas, they can be clearly recognized by means of optical sensors, and it is not difficult to synchronize the cutting processes on the cigarette machine with the paper path so that the discrete areas become on each cigarette in the desired position near the filter.
- the air permeability in each of the perforated areas is constant. Therefore, the perforator only needs to be turned on and off at a timing corresponding to the paper web speed. This is much easier than following a continuous air permeability profile. Also, to perforate discrete areas of various but within the range of constant air permeability, there is no difficulty in that the perforation performance can be easily adjusted each time the perforator is turned on and off.
- Figure 1 is a schematic representation of a cigarette with an exemplary
- the cigarette paper 1 which comprises a first perforated region 2, a second perforated region 3 and further perforated regions 4.
- the cigarette paper 1 is partially unrolled from the tobacco column 7 of the cigarette.
- Figure 2 shows the special perforation pattern of the cigarette paper to the desired
- This pattern results from the typical manufacturing process machine-made cigarettes.
- an endless tobacco rod is first formed, which is then cut along the lines B into portions twice the length of the tobacco rod of a cigarette is shared.
- this double-length part of the tobacco rod along the line C is divided into two parts and moved apart in the axial direction, so that a double-length filter plug can be inserted.
- the entire double-length filter and part of the tobacco strands following the filter are glued and wrapped with a double-width tipping paper.
- this double cigarette connected by the double-length filter is divided into two cigarettes by a final cut through the center of the filter.
- the pattern to be produced by perforation on the cigarette paper can also be adapted to other methods of cigarette production.
- the starting point of the examples is a cigarette paper with the following data:
- the diffusivity is the diffusion constant of the paper [cm 2 / s] divided by the thickness of the paper [cm]. It is a transfer coefficient and thus describes the gas flow passing through the paper at a given concentration difference, irrespective of the thickness of the paper.
- the diffusivity can be measured, for example, with a C0 2 diffusivity meter from Sodim.
- This cigarette paper was now electrostatically perforated over the entire area, so that an air permeability of 50 CU, 100 CU, 150 CU and 200 CU was achieved.
- the distance is the distance from the leading edge of the tipping paper to the beginning of the discrete perforated area.
- the comparable air permeability is the air permeability of the fully perforated cigarette paper, which achieves the same levels of smoke on the test cigarette as the perforated cigarette paper in discrete areas.
- the inflammation tendency was first determined according to ASTM E2187-04b. According to ASTM E2187-04b, 40 cigarettes per cigarette paper were tested and all samples quenched 90% or more of the tested cigarettes, with no statistically significant differences between the samples.
- the cigarettes were further smoked according to the method described in DIN ISO 4387.
- a volume of 35 cm 3 is sucked in every minute for 2 seconds at the mouth end of the smoldering cigarette. This suction of 35 cm 3 is called a train.
- the process is repeated until the cigarette has smoked so far that it falls below a predetermined by the standard minimum length.
- the smoke is sucked through a glass fiber filter, which is later chemically analyzed. From this, the nicotine-free dry condensate ("tar”) and nicotine are determined and usually expressed in mg per cigarette.
- Machine smoking was carried out on a Borgwaldt RM20 smoking machine, but modified so that each pass on the cigarette was passed through another glass fiber filter so that after analysis, the smoke levels of each train could be determined. For each paper sample, 20 cigarettes were smoked by machine in this way.
- the first train Since the first move, the cigarette is lit, the first train is a special feature in terms of its Abrauch tone and is excluded from the considerations. It is also possible with standardized, machine smoking that the last train can not be completed, because the cigarette falls below the prescribed minimum length during the turn. Such a train ("fractional puff") is called Fraction of a whole train registered. To simplify the presentation, therefore, the last move is excluded from the considerations.
- the comparative value is the ratio of tar between the penultimate and second traction for a cigarette with a full perforated cigarette paper having the air permeability indicated in Table 1.
- the concentration of perforation in discrete areas near the filter allows a reduction in air permeability since the perforated areas are now in a region where the difference between the ambient air pressure and the pressure inside the tobacco rod is higher during smoking is as in closer to the gluten cone located regions.
- the full-surface perforated paper has an air permeability of 50 CU over a length of 60 mm, while sample A is only perforated to a tenth of this length, namely 6 mm. It would be expected that in order to produce the same air flow in the cigarette, the 10-fold air permeability, ie 500 CU is needed. Surprisingly, however, it has already been found that 160 CU are sufficient to achieve the same levels of exhaustion.
- the smoke values comparable to a cigarette with a cigarette paper perfused over the entire area can be achieved with an even lower air permeability.
- the perforated area is now twice as large.
- the air permeability could be half that, ie 80 CU.
- the second perforated area is farther from the mouth end and thus in a region where the pressure difference is not so great. In addition, it is consumed during the smoking process.
- the patterns A, G and H differ only in the distance of the perforated area from the leading edge of the tipping paper. In pattern A it is 1 mm, in pattern G it is 3 mm and finally in pattern H it is 5 mm. Although it can be seen that there is an improvement in the uniformity of the tension profile over the full-surface perforated paper, the extent of this improvement decreases rapidly as the first perforated area too far from the leading edge of the tipping paper. Specifically, the improvement decreases from 13% to about 8% at 3 mm and to only 5% at 5 mm distance. It will therefore strive to keep this distance at least less than 10 mm and preferably less than 5 mm.
- the patterns A, J, K and N initially differ in the width of the perforated area. Accordingly, the air permeability was adjusted to achieve comparable levels of smoke.
- pattern A with a width of 6 mm, it is 160 CU, with pattern J with a width of 7 mm about 140 CU, with pattern K with 9 mm width still 1 10 CU and with pattern N with a width of 20 mm finally only 80 CU.
- the minimum width is limited by the maximum air permeability that can be achieved in such a narrow range by perforating without unduly compromising the tensile strength of the paper. Taking Pattern B, with 650 CU on a width of 6 mm, as a guide, you will need to perforate a nominal 2 mm wide area with 1950 CU to achieve the same result. This is already a very high air permeability, which is already difficult to achieve with perforators in such a small area, which is why the width of the perforated area should be between 2 mm and 25 mm, preferably between 4 mm and 12 mm and more preferably between 5 mm and 9 mm.
- patterns L and M show that the air permeability of the two perforated areas need not be equal. Based on the results so far, it seems advantageous to perforate more strongly that area which is closer to the mouth.
- the air permeability of the first region is about 150% of the air permeability of the second region.
- the improvement in the ratio of the tar values is about 13% (pattern L) comparable to a paper with a perforated area of pattern A.
- each area should be less perforated than its predecessor, as viewed from the mouth end to the cone.
