The technical field

The present invention relates to Smoking articles such as cigarettes, and to a method and apparatus for their manufacture.

The background to the present invention

According to the method of manufacture of cigarettes, for example, described in patent US 4771794, offered the use of a vacuum belt conveyor, the conveyor takes the tobacco from the hopper and forms a rod of tobacco, which is fed into the section (area) of the valve machines for making cigarettes where tobacco rod is wrapped in paper. Rod of tobacco, formed in a section of the vacuum belt conveyor, generally does not have enough uniform mass or density to be used directly as a high-quality cigarettes. Accordingly, the tobacco rod is cut edge using limiter removal of excess mass or density.

The removal process is carried out through a set of pruned disks. Cutting discs contain two coplanar rotating disk adjacent to each other. Cutting discs cut off the excess mass or density of the tobacco rod, passing over or between them through the use of vane wheel or brush, which rotates under the disks. The disks and the brush can be moved up and down, so that when necessary the STI, to remove more or less of tobacco.

Cigarettes often have a high density packing of tobacco on one end of the cigarette, which prevents the loss of loose tobacco of the cigarettes. Known cutting disks adapted to this by pockets in the trim discs, which allow a greater quantity of tobacco to pass through the disk at either end of the tobacco rod section of the valve of the machine. In particular, rotation of the two pruned disks are synchronized, so that the pockets form a symmetrical profile with respect to the cylindrical axis of the cigarette. This method allows to form a tight end tobacco on the open ends of the cigarettes. The use of such tight ends have proven to be very effective for keeping tobacco inside cigarettes.

In contrast, the rest of the Central area (main part) cigarette provides basically constant density of tobacco, and cutoff disks for the manufacture of such cigarettes give the appropriate form.

The invention

One variant of implementation of the present invention a device for the manufacture of Smoking articles containing the limiter at least one cutoff disk, configured for cutting the tobacco rod of a Smoking product to obtain at least one end area and high density of tobacco. Cut the disk is additionally configured to trim the core area of the tobacco rod to the main area had a variable mass of tobacco per unit length. The main area is different from the end region(s) with higher density.

In another variant implementation of the present invention a device for the manufacture of Smoking articles containing the limiter at least one cutoff disk, configured for cutting the tobacco rod of Smoking products. The edge of the trim disk includes a first segment corresponding to at least one end region with a higher density of tobacco, the second segment corresponding to the area of the main field, which must be equipped with a double zipper, and a third segment corresponding to the rest of the main plot area. The level of the third segment is intermediate relative to the level of the first segment and the second segment (in some embodiments, the implementation of this level may vary within the segment).

The present invention also offers a Smoking article containing the tobacco rod, at least one end region with a higher density of tobacco. The tobacco rod further comprises a main area, which has a variable mass of tobacco on e is inico length. The main area is different from the end region(s) with high density. The Smoking article further comprises an inner wrapper and an outer wrapper. The inner wrapper has the same length with the first section and the outer wrap lasts at least over the entire core area. In any given position along the first section of the mass of tobacco per unit length and the size of the inner wrapper in combination, a constant density of tobacco along the first section.

In another variant implementation of the present invention offers a Smoking article containing a tobacco rod with a scope with variable mass of tobacco per unit length along the tobacco rod. The density of the tobacco in this area is essentially constant. In other embodiments, implementation of the present invention proposes a method and apparatus for the manufacture of such Smoking articles.

The present invention also features a method of making Smoking articles. This method involves cutting the tobacco rod of a Smoking product to obtain at least one end region with a higher density of tobacco. The method further comprises cutting the core area of the tobacco rod to the main area had a variable mass of tobacco per unit length. The main is blast differs from the end region(s) with high density of tobacco. Pruning is performed using at least one of the bounding disk configured for cutting the tobacco rod of a Smoking product to obtain at least one end region with a higher density of tobacco, and trimming the main region of the tobacco rod to the main area had a variable mass of tobacco per unit length and differed from the aforementioned at least one end region with a higher density.

As for the famous Smoking products, end region with high density of tobacco (compared to the density of the tobacco core area may be provided at the open end Smoking products, and some tobacco products may also contain terminal region with high density of tobacco at the end of the filter. The main area of Smoking products represents a portion (body) of the tobacco rod between the end areas with high density (if on one end of the tobacco rod density is not increased, then the main plot actually involves or extends all the way to the end). In contrast to well-known cigarettes, the main area of the tobacco rod is subjected to trimming to get the variable mass per unit length.

In one embodiment, trimming the main area in which incorporates both the formation of the first section of the main area with a smaller mass of tobacco per unit length, than on the second site the main area. The mass of tobacco per unit length of the first section of the main area can be essentially constant or variable along the length of the first section, depending on the desired profile of tobacco. The first section may be continued from one end of the base region (e.g., end of the filter Smoking products) partially along the core area, the second area containing the rest of the core area. Another possibility is that the first section can contain the Central section of the core area, the second area containing the rest of the core area. In other embodiments, the implementation can be made more complex configuration from the point of view of the number of intermediate layers and/or levels of the mass of tobacco per unit length.

In one embodiment, features a Smoking article with the inner wrap and the outer wrap. The inner wrapper has the same length with the first section, and the outer wrap lasts at least over the entire main area (and basically any end region with high density). The inner wrapper may be provided for various purposes, for example to enhance the flavor and/or reduce the supply of some components of smoke to the consumer during Smoking. Reduced quantities of the tobacco in the Smoking area of the product with double wrap helps to avoid high density of tobacco in this area. For example, in one specific embodiment, at any given position of the first land mass of tobacco per unit length and the size of the inner wrapper can be combined to obtain a constant density of tobacco along the first section (providing compression of the tobacco rod when applying wrappers). This helps to ensure a constant density of tobacco for the main plot, which allows to improve the characteristics of the area and the treatment of the Smoking product, as well as to avoid potential problems during manufacturing, such as folds when applying an outer wrapper or breaks rod (screening tobacco through the wrapper).

Note that the mass of tobacco per unit length can vary even in Smoking products without internal or double wrap. For example, such a change can occur to improve filtering performance (taking into account the fact that the cigarette is lit, the degree of filtering provided by the tobacco rod is reduced), it is possible to reduce product cost, etc.

In one embodiment, the edge of the bounding disk(s) varies in level in accordance with the variable mass of tobacco per unit length of the main area. For example, the edge of the bounding disk(s) can include a first segment corresponding terminal region with increased mass of tobacco n is the unit length, the second segment corresponding to the area of the main field, which must be equipped with a double zipper, and a third segment corresponding to the rest of the site core area and located at an intermediate level relative to the level of the first segment and second segment. Cropping can be done using a pair of such disks.

In one embodiment, advanced cropping is performed using at least one restrictive brush. The radius of the bounding brush is changed in accordance with a variable mass of tobacco per unit length of the main area. For example, the radius of the bounding brush may have a first value corresponding terminal region with increased mass of tobacco per unit length, the second value corresponding section of the main area, which must be equipped with a double zipper, and a third value corresponding to the rest of the plot is the main area where the third value is relative to the first intermediate value and the second value.

In another embodiment, the bounding disk made smooth circumference (i.e. has a constant level), while restrictive brush has a constant radius. The distance between the cutoff disk and the Central axis of the tobacco rod is adjustable to fit is provided with the necessary change of the mass of tobacco per unit length of the main area. In this case, the bounding disk and brush narashima are connected to each other and move up or down together to trim more or less of tobacco from the tobacco rod.

The device and the Smoking article of the present invention also have advantages due to the additional features described above in relation to the implementation of the method.

Detailed description

Figure 1 shows a schematic top view of a device 1 for the manufacture of cigarettes in one variant of implementation of the present invention. The device comprises a pair of coplanar rotating disks 10, 20 are essentially adjacent to each other. The disks rotate in opposite directions relative to each other, so that the disc 10 is rotated clockwise, as indicated by the arrow a, and the disc 20 rotates counterclockwise, as indicated by the arrow a'. The disks 10, 20 are known as cutting disks and form part of limiter removal of tobacco from the tobacco rod.

During the operation of the tobacco rod 50 is moved through the two disks along a path parallel to the longitudinal axis of the tobacco rod. The path of the tobacco rod is essentially p is ecstasy a tangent to the two rotating disks. This path divides in half and perpendicular to the line connecting the centers of two rotating discs. Moving the tobacco rod along its path is in the direction opposite to the moving plots two rotating discs directly under the tobacco rod. Thus, as shown in figure 1, when the two disks are rotated so that they both move down (on this page) in close proximity to the path of the tobacco rod, itself the tobacco rod is moved up along this path (as indicated by the arrow B). This provides relative movement of the tobacco rod 50 and the rotating discs 10 and 20, which is used to perform the trimming.

Two rotary disc 10 and 20 in the device 1 are the same. The peripheral region of each of the rotating disk 10, 20 has three different levels or depths (measured in the direction perpendicular to the disk plane). The first area indicated by 15 in figure 1, is where the edge of the disk is on the same level as the main sector of the disk. This disk area is the highest, i.e. closest to the Central axis of the tobacco rod 50, and, thus, is used to trim the greatest amount of tobacco from the tobacco rod 50.

The second area indicated by 17 in figure 1, is where the depth of the edge section of the disk Nai is great. In other words, the region 17 lies at the lowest level relative to the plane of the disks 10 and 20 (and therefore as far from the Central axis of the tobacco rod 50). Therefore, this section of the region 17 of the disk is used to trim the smallest amount of tobacco from the tobacco rod 50.

The third area, designated 16 in figure 1, is where the depth of the area of the edge of the disk has an intermediate value compared to the regions 15 and 17. Therefore, this area of the edge of the disc is used to trim the intermediate quantities of tobacco from the tobacco rod 50, which is less tobacco than the area 15, but more tobacco than region 17.

Both rotary disc 10 and 20 in the device 1 have the same pattern around the circumference. Moreover, the pattern of the disk 10 in a horizontal direction aligned with the pattern of the disk 20 to synchronize the phase angle for the disk 10 with the phase angle of the disk 20 (providing the opposite direction of rotation). Therefore, when a specific area of the edge of the rotating disk 20, for example, the area 16, is in contact with the tobacco rod 50, the same region (i.e. region 16) of the rotating disc 10 is also in contact with the tobacco rod 50. This provides a symmetrical cutting the tobacco rod 50 relative to the line corresponding to the center (long) axis of the tobacco rod 50.

On figa shown Horiz is Talnoe section of the disk 10 (i.e. perpendicular to the disk plane) along the line S1 in figure 1. The diameter of the cross section coincides with the position of the deepest pockets on the disk, the corresponding region 17. Also on figa seen stepped up to the intermediate level for region 16. Speed increased to the highest level of disk area 15, which is located in the same plane with the main part of the disk is visible only on figa (because of the curvature of the disk).

Figb can be seen as a circular cross section of the disk 10; in other words, it is obtained by posting on the arc S2 in figure 1, but always when viewed in the direction of the center of the disk 10. As you can clearly see on figb, region 17 forms the deepest part of the edge of the disc 10. Region 16 intermediate depth is located on one side of the field 17. The rest of the edge region 15, is on the same level as the main part of the disk.

In the embodiment, by figb level region 16 is approximately 0.25 mm below the level of the region 15, while the level of area 17 is approximately 0.25 mm below the level of the region 16. Each pocket lasts approximately 7 mm radially inward towards the center of the disc 10 (after which the disk level returns to the level of region 15, i.e. the main part of the disk). Corner (circumference) length of each region 17 is closer the LNA 12 degrees; similarly, each segment region 16 has an angular length of approximately 12 degrees. The angular extent of the region 15 is approximately 54 degrees (it should be understood that these dimensions and angles are given for example only and may be different for different embodiments).

Figure 3 shows the bounding brush or vane wheel 300 for use in the device 1 for manufacturing of figure 1 according to one variant of implementation of the present invention. Wheel 300 is located under the trim disks 10, 20, i.e. on the opposite side disks 10, 20 from the Central axis of the tobacco rod 50. In contrast to the disks 10 and 20, which are mounted horizontally, the wheel 300 is mounted vertically and rotated about the horizontal axis. This axis is shifted in the direction of movement of the tobacco rod 50. Arrow W in figure 1 lies in the same vertical plane as the wheel 300, and also indicates the direction of movement of the upper part of the wheel 300. In other words, a plot of wheel 300 directly under restrictive disks 10, 20 are moved in the direction of the arrow W, therefore, touches and sweeps brush over tobacco in the direction of the disk 10. (This is the excess tobacco is then returned for reuse in the hopper from which the vacuum belt conveyor forms a t boczny rod 50.)

Wheel 300 has a variable radius of curvature corresponding to the variable depth of cut disks 10, 20. Thus, area 317 wheels 300 with the smallest radius corresponds mainly deepest pocket 17 on pruned disks. Therefore, this part of the wheel removes the small amount of tobacco from the tobacco rod 50. Region 316 wheel 300 with an intermediate radius correspond mainly intermediate pockets 16 on pruned disks. Therefore, this part of the wheel removes intermediate amount of tobacco from the tobacco rod 50. Region 315 of the wheel 300 with the largest radius corresponds mainly to the highest level 15 pruned disks. Therefore, this part of the wheel removes the greatest amount of tobacco from the tobacco rod 50.

It should be understood that the drawing edge of the disks 10, 20 occurs (repeats) four times per revolution, while the radial arrangement of the wheel 300 meets only once per turn.

Therefore, the wheel 300 rotates four times faster pruned disks 10, 20, so that each turn of the wheel 300 corresponds to one occurrence of (repeating) pattern around the edge of pruned disks 10, 20.

Radial profile and the phase angle of the wheel 300 is configured to maintain synchronization with the edge of the trim disk. In particular, the peripheral rim of the wheel 300 Ude is zivaetsja close to the bottom edge of the trim disk 10, 20 to ensure proper removal of surplus tobacco, at the same time, ensuring that the wheel 300 is not engaged on pruned disks 10, 20 (or Vice versa). Therefore, the rim 300 operates in conjunction with the bottom side of the trim disk to remove varying amounts of tobacco from the tobacco rod 50.

As indicated in figure 3, the angular (circumference) length region 317 is approximately 98 degrees, the angular extent of the region 316 of approximately 45 degrees, the angular extent of the region 315 is approximately 172 degrees. These angles are determined by the need to provide clearance for pockets on pruned disks. Note that the angular extent of the region 317 is greater than the angular extent of the respective pockets 17, even when providing a fourfold speed increase frequency, due to the finite width of the wheel 300 (i.e., measured in a direction parallel to the axis of rotation). In particular, area 317 must secure clearance from the moment when the first part of the pocket 17 encounters near the surface of the wheel 300 (defined by the direction of rotation of pruned disks), until the last part of the pocket 17 releases far surface of the wheel 300. (It is clear that the angles mentioned above are only for illustration purposes and may be different on the I different variants of implementation.)

Figure 4 is given schematic representation of the tobacco rod 400 formed with the device fabrication of figure 1 according to one variant of implementation of the present invention. In this diagram, the arrow a indicates the axial direction of the tobacco rod. Figure 4 shows the profile or change the mass (per unit length) for the tobacco rod 400 created trim disks 10, 20 and wheel 300. Because the tobacco rod 400 basically has constant density (in terms of mass of tobacco per unit volume) at this stage of processing, the change of mass in figure 4 also corresponds to a change of thickness, for example, square cross-section or radius of the tobacco rod 400. (Therefore, we can assume that the arrow R in figure 4 indicates a radial direction of the tobacco rod 400.) Note that figure 4 presents are not to scale and for clarity, the change in mass or size exaggerated.

Sections 414 tobacco rod 400 with the smallest area or mass per unit length correspond to the highest part of pruned disks 10, 20, namely region 15, and section 315 of the wheel 300 with the largest radius. Sections 412 tobacco rod with the largest mass per unit length correspond to the deepest part of the cut disks 10, 20, namely region 17, and part 317 of the wheel 300 with the smallest radius. Region 413 tobacco CTE is life with intermediate mass per unit of length are in the intermediate portion of the trim disk 10, 20, namely region 16, and part 316 of the wheel 300 with an intermediate radius. Therefore, the entire area 412 has a large mass of tobacco per unit length than the section 413, which, in turn, a greater mass of tobacco per unit length than the section 414.

For the continuous feed of the tobacco rod 50 to the device 1 for the manufacture of cigarettes, the picture changes, shown in figure 4, is repeated. The repetition period corresponds to the length of two cigarettes. In particular, the section of the tobacco rod 400 between dashed lines C1 and C2 are ultimately used to form a pair of cigarettes. Thus, sections 400A, 400B, 400C and 400D tobacco rod 400 over how different cigarettes. It should be noted that one revolution of pruned disks 10, 20 corresponds to the production of eight cigarettes (four pairs), because the figure of edges pruned drive meets four times around the circumference of the trim disk with an equal interval. (Obviously, these relationships can vary depending on the specific device to be used for manufacturing.)

Although all cigarettes that are generated from the tobacco rod 400 have the same profile changes, two cigarettes in each pair of cigarettes have opposite orientation. In particular, after section 400B and 400C tobacco rod is formed by a cut along lines C1 and C2, two outdoor conc the cigarettes are on the opposite (far) end of this section of the tobacco rod.

Dashed line C1 is divided into two section 412A, representing the maximum thickness of the tobacco rod 400 (and the corresponding deepest area of pruned disks 10, 20). In this section 412A is divided by a partition D1, which ends in the cigarette 400A, and section D2, which ends in the cigarette 400B. Therefore, the open end of the cigarette 400B contains a section 412A, or, more specifically, half of the section 412A, denoted by D2 in figure 4. Similarly, the open end of the cigarette 400C contains the first half of the plot 412B.

After complete sections C1 and C2 of the tobacco rod, corresponding to the cigarettes 400B and 400C, wrapped in a wrapper (as described in more detail below). During application of the wrapper section 412A (i.e. D2) is used to form a dense open end of a cigarette 400B, because it contains the maximum mass of tobacco per unit length. Similarly, section 412B is used to form a dense open end of a cigarette 400C. On an additional stage of manufacture (after wrapping) section 414 is divided along the dashed lines C3, and between section 414A and section 414B inserted into the filter. This filter is then divided by two, which completes the manufacture of individual cigarettes 400B and 400C.

The term "core area" is used herein to refer to a section of the tobacco rod, which excluded the raft the first end(s) - i.e. plot, except for the area(s) with high density of tobacco in the open end of a cigarette, and optionally also at the end of the filter. In an ordinary cigarette, the mass of tobacco per unit length in a generally constant along this main site, thereby ensuring constant quality while Smoking and handling.

However, it is assumed, see, for example, document WO 2005/082180 that the main plot of cigarettes may be provided with an inner wrapper in addition to the usual tissue paper used for the outer wrapper. This inner wrapper may be used to provide additional flavoring. Another potential use of the inner wrapper is to reduce the supply of some components of smoke to the consumer when Smoking. This is caused by the need to ensure a constant supply of smoke from cigarettes as Smoking. Thus, the tobacco within the tobacco rod provides some degree of filtering, but because the tobacco is burned, the corresponding filter is reduced. The use of the inner wrapper containing an absorbent material, towards the end of the cigarette filter reduces the flow components of the smoke the smoker when the final puffs, thereby, achieves smoother profile for all delays (especially for products with low output resins).

In nekotoryye inner wrap may be located between the two tight ends tobacco, while other cigarettes inner wrap may continue along the entire length to the end of the filter, without tight end on the end of the filter. This reflects the fact that providing a tight end on the end of the cigarette filter contributes mainly to the manipulation of the machine with the tobacco rod during manufacture prior to the introduction of the filter (because after the introduction of the filter, the filter itself provides the hold of tobacco in a cigarette). Additional thickening of the inner wrapper (compared to conventional tissue paper) can also facilitate manipulation of the machine with the tobacco rod, thereby reducing or eliminating the need for a tight end tobacco end of the filter (assuming that the inner wrapping is continued along the entire length to the end of the filter).

If the inner wrap continues along only part of the main plot of the cigarette, the cigarette has a double wrap (inner wrap and normal tissue paper) for this part of the cigarette, but a single wrapper (just an ordinary tissue paper) along the rest of the cigarette. For example, conventional tissue paper may have a thickness of 0.05 mm, while the inner wrapper may have a thickness of about 0.17 mm, compared with a total radius of cigarettes approximately 3,9 mm (it is Obvious that these figures are given only as p is of iMER and may vary for a particular cigarettes and accordingly, wrappers.)

The double wrapper, continuing along only part of the main plot cigarette creates a gap across the thickness of the shim. This can lead to feeling heterogeneity cigarette in his hand, rupture of the outer paper wrapper and/or rupture of the rod. In addition, the tobacco may be more compressed under a double zipper, which leads to unstable characteristics when Smoking.

Therefore, according to one variant of implementation of the present invention the profile shown in figure 4, is used to match the cigarette with (partial) double wrap. In particular, the Central region 414 cigarette with a smaller mass of tobacco per unit length corresponds to the area provided with double zipper, because sections 413 with a larger mass of tobacco per unit length provided simply with a single wrap. This also ensures that the inner wrapping in fact was located in the region of smaller radius of tobacco.

In one specific embodiment, a long roll (external) paper for the wrappers of cigarettes is served on a periodic basis with portions of the inner wrapper. The size and span for this inner wrapper corresponds to the size and amount of sections 414 with reduced thickness tobacco tobacco rod 400, thereby each section 414 with a reduced thickness of the tab is ka gets a double wrap.

The thickness of the inner wrapper corresponds to approximately the depth of field 414 compared to region 413 with the availability of compression of the inner wrapper and/or tobacco, when superimposed outer wrapper, namely cigarette paper. (Thus, the depth of 0.25 mm pocket trim in the disk 10 slightly more than the thickness of 0.17 mm inner wrapper, because the imposition of a wrapper tobacco is somewhat compressed.) This helps to maintain a constant density of tobacco along the length of the cigarette in place of the gap, where it starts/ends in an inner wrap and the reduction or elimination of local compression or tension on the outer wrapper in this gap. This, in turn, allows to improve the performance when accessing and Smoking cigarettes (partial) double wrap.

The profile in figure 4 corresponds only to the tight end tobacco on the open end of a cigarette, but not the end of the filter. As mentioned earlier, one reason for this is that the inner wrapping itself contributes to the strength at the end of the filter, thereby reducing or eliminating the need for a tight end in the manufacture. It also reflects the fact that the mechanical equipment for forming a tight end on either ends of the cigarettes are more difficult. In particular, the presence of tight ends on both ends of cigarettes mo the em to provide a plot of 15 pruned disks 10, 20, the pocket containing the same depth, and that the pocket 17, but without the intermediate ledges 16 on each side. This abrupt change in the depth of the cut disk can cause problems with clipping, and from the perspective of abrupt changes in speed crop of tobacco, and also from the point of view of the configuration of the wheel 300 to delineate, but without the collision of such a profile disk. One possibility could be the introduction of a high density thick end within the plot with double zipper, while the radius of the tight end can match only afford 16 (not pocket 17).

In one embodiment, instead of the double wrapper on the Central plot cigarette double wrap can be placed on the cigarette otherwise. In addition, some cigarettes may be provided with a different or more complex set of changes in the mass per unit length than shown in figure 4, for instance, more mass per unit length and/or more intermediate layers between the different levels. In addition, the intermediate layers can be used in a variety of profiles, such as bench, slant, curve, etc. as described in more detail later).

Although the device for the manufacture of figure 1 uses multi-level rotating disks 10, 20 to obtain changes in the thickness of the tobacco rod such as shown at F. g, in other embodiments, the implementation can be used completely flat disk in combination with cutoff wheel constant radius. Then the Cam mechanism provides adjustable compression of the tobacco rod 50 until it reaches the stopper. If the applied relatively strong compression of the tobacco rod 50 has a relatively small cross-section, therefore, the limiter removes less tobacco because tobacco is mostly closer to the Central axis of the tobacco rod, therefore, less tobacco lies below the plane of the bounding disks). Therefore, the mass of tobacco per unit length obtained tobacco stem relatively large. Conversely, if the applied relatively little compression of the tobacco rod 50 has a relatively large cross section, therefore, the limiter removes more tobacco - i.e. the mass of tobacco per unit length of the received tobacco rod is relatively small. Accordingly, it is possible to use such a Cam mechanism to obtain a thickness profile or mass in figure 4 (or any other desired profile). One of the advantages of this method is that a different profile can be obtained simply by replacing the Cam mechanism without replacing the trim disk or wheel.

A similar advantage can be realized in the device for manufacturing, which limit the positive drive and the wheel to move up and down together, rigidly connected to each other, to and from the tobacco rod 50, which allows you to change the quantity of tobacco cut from the tobacco rod 50. In particular, the movement of the disk and the wheel can be controlled in accordance with the desired thickness changes facing the tobacco rod, for example, as shown in figure 4.

Although an implementation option for 1-4 refers to the limiter with two step changes of level (on a cigarette), there are many other configurations. Figure 5 shows the bounding disk with a single step change, and one gradual level change (on a cigarette). In particular, the bounding disk 510 in figure 5 is provided with a first region containing a deep pocket 517 for the formation of a tight end, and then a second area of the intermediate level 516. Finally, there are third area 515, which basically has the highest, although gradually changing level. Thus, where the third region is connected with the second region, the level of the third region corresponds to the second region. The level of the third area gradually increases from the second region, until you reach the main part of the disk. The pattern is then repeated in the reverse direction, thereby the level of the outer area of the disk again gradually decreases in the direction to the other intermediate about the Asti, and then another deep pocket. These changes in the level shown on the profile view 6 (which corresponds to the geometry figb).

The disk 510 allows you to get 8 cigarettes per turn, and each quarter of the disk creates a pair of oppositely directed cigarettes (as the disks 10, 20 of figure 1). For example, region A and A1 in figure 5, which are formed in a single deep pocket 517, provide tight ends for two different cigarettes. First, the cigarette contains the first tight end region A, the second area with an intermediate mass of tobacco per unit length, denoted by B and is formed by level 516, and a third region with slowly varying mass of tobacco per unit length, denoted by C and is formed by gradually changing level 515. Similarly, the second cigarette contains the first tight end, formed by the area A1, the second area with an intermediate mass of tobacco per unit length corresponding to B1 and formed through the level 516, and a third region with slowly varying mass of tobacco per unit length corresponding to C1 and formed at the expense of another gradually changing level.

In one embodiment, the region C to the first cigarette continues between the intermediate section (labeled B) and filter cigarettes. The maximum height of the edge is hranitelno disk corresponds to the place, where the area of C must be adjacent to the filter. Similarly, for the second cigarette in a pair, the maximum height of the edge of the bounding disk corresponds to the place where C1 should join the filter.

In one embodiment, the pocket 517 formed at a depth of approximately 2.5 mm below the field 516, while the level of field 516 is approximately 2.5 mm below the highest point of the section 515. In other words, a gradual reduction section 515 (corresponding to region C or C1) creates a General decline of approximately 2.5 mm, which approximately coincides with the slowdown from the site 516 to afford 517. (Obviously, in other embodiments, the exercise may be other changes of level.)

7 shows the bounding brush or wheel 700 for use with the bounding disk 510 in figure 5 and 6), one variant of implementation of the present invention. As in the previous embodiment according to Fig 3, the guide wheel 700 generates one pair of cigarettes per revolution, and thus, has a speed four times the frequency of rotation of the disk 510 (but in other embodiments, the implementation can be used in other relations). The deepest region 717 (i.e. with the smallest radius) restrictive wheels 700, marked A and A1, is used to form pairs adjacent to each other tight ends.

(Of all IDNO, what region A and A1 wheels 700 correspond to the areas A and A1, respectively, of disk 510 in figure 5. In particular, the rotation of the wheels 700 and disk 510 synchronized so that the area of A disk 510 and the area of A wheel 700 both reached the tobacco rod together, similar to the areas A1.)

The staging area 716 (i.e. the region with an intermediate radius) restrictive wheels 700 indicated In (and B1), is used to form region with a standard mass of tobacco per unit length. Finally, the area 715 restrictive wheels 700 with a gradually increasing radius, denoted by C, is used to form region with decreasing mass of tobacco per unit length, thus, the end of the filter to the tobacco rod has the lowest level of the mass of tobacco per unit length. This pattern is then repeated in the opposite direction, so that additional rotation of the height of the edge of the trim disk for area C1 gradually decreases to an intermediate level region B1, which, in turn, decreases to a level pocket 717, due to which the area A1 forms a tight end. (Also, area B, B1, C and C1 wheels 700 correspond to the areas B, B1, C and C1, respectively, of the disk 510.)

Changing the radius of the bounding wheel 700 is shown by the dashed line curve W, which forms an arc of constant radius that corresponds to the maximum radius for rancitelli wheel 700. This maximum radius is set to 720, which coincides with the boundary between regions C and C1. (In one embodiment, this is the place where it will eventually be cut between the two cigarettes tobacco rod formed during one revolution of the wheel 700 to ensure that the introduction of filter material.)

The radius of wheel 700 is reduced with a change in angular position in the direction from the position 720, as can be seen by the increasing divergence between the arc W and the outer surface of the wheel 700. This decrease is the wheel radius gradually becomes larger with increase of the angle at site C to the position 721, which represents an intermediate layer from area C to area B (which has a constant intermediate radius). There is a corresponding decrease on the other side of the wheel 700 in area C1 around the circumference to position 722, which corresponds to the intermediate layer from the plot C1 to section B1.

The total change of the radius of wheel 700 in area C or C1, i.e. the change from the position 720 circumference to position 721 or 722, shown on Fig.7. the arrow 725. It should be noted that this total change of radius 725 approximately equal to a stepwise change of the radius of the intermediate layer from the field 716 B to area A 717 (or speed change, shown in figure 3).

On Fig schematically shows the tobacco rod formed with the bounding disk 510 (and wheels 70D). Fig mainly corresponds to figure 4, which also region 400A, 400B, 400C and 400D, each end of another cigarette. In addition, each cigarette contains three sections, 812, 813 and 814. However, unlike figure 4, Fig no step change in the mass of the tobacco rod, except for the portion from the intermediate layer to a tight end (i.e. between areas 812A and 813A). Rather, after an intermediate step 813A, 813B, the mass of tobacco per unit length gradually decreases to the area 814A, 814B IN to the minimum value, which is achieved at the section line C3.

Profile on Fig can be selected to encourage the management of features of Smoking cigarettes. For example, the mass of tobacco per unit length can be reduced near the end of the cigarette filter that provides the regulation of the feed rate of the components of the smoke the smoker as combustion of the cigarette. In one embodiment, the change of the mass of tobacco per unit length distributed within a single (standard) wrapping tissue paper (which leads mainly to the reduced density of tobacco near the end of the filter).

Another possibility is to replace the really supplanted tobacco inner wrap to provide additional flavoring, more uniform feeding of the components of smoke, etc. as proposed in the aforementioned document WO 2005/082180 .However, in addition to the rectangular inner wrapper (combined with the axial direction of the tobacco rod) for the wrapper can be used in other forms.

Figure 9 shows examples of different forms of the flap to the wrapper (obviously, there are many other forms): (a) rectangular; (b) triangular; (C) diamond; and (g) the ellipse. Large arrow at the bottom of figure 9 shows the direction of combustion along the axis of the cigarette. Note that the length of any given wrapper may be such that it is continued along the entire or only part of the tobacco rod of the cigarette. Perpendicular to the direction of the arrow represents the direction along the circumference (when the wrap is wrapped around the cigarette). Depending on the width of the wrapper it can continue around the entire circumference of the cigarette.

Rectangular wrap (a) can be used with the profile of tobacco, shown in figure 4. In other words, the wrapper must match the area of the small mass of tobacco 414A, 414B. As described above, the thickness of the shim may correspond to the reduction of weight of tobacco, providing, thereby, a constant density of tobacco along the length of the tobacco rod by any intermediate layer(s) between plots with and without inner wrapper.

Triangular cut-outs (b) can be used with the profile of tobacco, shown in Fig. In other words, the wrapper must match the region of the reduced mass of tobacco 814A, 814B. Reducing the width of the wrapper (and therefore coverage around the circumference) along the length of the tobacco rod is suitable is to reduce the mass of tobacco, so the density of tobacco again is constant along the length of the tobacco rod by any intermediate layer(s) between sites without an inner wrapper and an inner wrapper, and also along the length of the inner wrapper.

One of the reasons for the use of triangular shim (b) is a creation by wrapping a more gradual effect. For example, if the wrapper provides the flavor, the amount of the original distributed flavoring, when it begins to burn the narrow end of the triangular wrapper, is relatively small (because the wrapper narrow). The amount of flavoring then gradually increase as Smoking cigarettes to more and wider sections of the wrapper. This gradual shift, and then amplification of the fragrance may be more attractive to consumers than dramatic effect rectangular shim (s).

Although the triangular cut-outs (b) has a gradual effect, it ends abruptly (like a rectangular wrap (a)). Although this may not be noticeable if the inner wrap is adjacent to the filter (because at this point cigarette in any case ends), two wrappers, and in the form of a rhombus, and in the form of an ellipse ((C) and (d), respectively) provide a gradual action, as well as the gradual completion of the internal wrapper.

Another reason to ensure the progressive reduction that the women of the wrapper along the length of the tobacco rod may be compensating for a decrease in the rest of the length of the cigarette. For example, because the aroma from the inner wrapper now occurs closer to the smoker, the width of the inner wrapper, required to achieve a given strength of fragrance for Smoking, can also be reduced towards the end of the cigarette filter.

Therefore, it is obvious that there are many potential factors that affect the desired weight per unit length of the tobacco cigarettes along (with or without an inner wrapper). Respectively, can be created many different configurations of the mass of tobacco per unit length of the tobacco, in addition to shown on figure 4 and 8. Moreover, these profiles of tobacco can be obtained using any suitable device, such as a restrictive system, shown in the drawings, the Cam mechanism etc.

Thus, the expert in this field will understand the ability of many possible modifications and changes to the described embodiments.
