Cigarette maker with modified burn rate {APPARATUS FOR MAKING CIGARETTE WITH BURN RATE MODIFICATION}

This international application is filed on March 14, 2003, filed on November 19, 2002, and is part of US Patent Application No. 10 / 299,231, which claims priority and benefit to this application. It is a continuation of ongoing US patent application Ser. No. 10 / 389,072, which claims priority and benefit to this application.

The present invention relates to a cigarette having a modified combustion rate and a cigarette manufacturing apparatus for producing the cigarette.

The modification of this tobacco of the present invention alters the tobacco leaf of the tobacco paper such that the tobacco wrapper is adjacent to a strip wrap forming a coaxial region of the high diffusion region and a coaxial region of the low diffusion region. It involves adding. These partial double wrap cigarettes show a modified burn rate such that the standard rate of smoking of the cigarette is changed so that it will slow down significantly or turn off by itself depending on the desired result. In addition, partial double wrap tobacco means that the surroundings of the cigarette are not partially double, but partially double.

A cigarette with a modified burn rate is shown in FIG. 1 and shown as a partial double wrap cigarette 10. As shown here, the partial double wrap cigarette 10 of the present invention comprises a standard tobacco of tobacco 13 extending from the exposed end to the filter 15. The outer wrap of tobacco paper 12 surrounds the border of the cigarette holder 13. Inside the outer wrap tobacco paper 12 there are separate partial inner wrap layers 14a, 14b, i.e., strips. The separate partial inner wrap layers 14a, 14b act as burn rate modifiers for the cigarette 13 by changing the combustion properties of the cigarette 10. As can be seen from the embodiment shown in FIG. 1, the inner wrap layer strip is coaxial with the cigarette 13 and can substantially extend the length of the cigarette from the exposed end to the filter 15. In this embodiment, by inserting the separate partial inner wrap layers 14a, 14b extending coaxially to the cigarette rack 13, the filling density of the cigarette, the porosity of the outer wrap paper 12, the additives to the outer wrap, the separate Modifications may be made to the burn rate of the cigarette in such a way that the burn rate may be modified depending on the width of the partial inner wrap layers 14a, 14b of, the porosity of the inner wrap layers 14a, 14b, and additives to the inner wrap strip. have. Alternatively, the inner wrap layer can be shortened or extended in various directions so as not to extend the full length of the cigarette 13. Thus, based on combining the elements mentioned herein, many variations can be made to the burn rate of the partial double wrap cigarette 10 of the present invention.

As depicted in FIG. 1, the partial double wrap cigarette 10 of the present invention with modified burn rate characteristics has an outer wrap paper having first and second separate partial inner wrap strips 14a, 14b. And (12). The outer wrap tobacco paper 12 may be a general porous paper that usually exhibits a porosity of 15-80 Coresta units. At least a portion of the inner wrap layer, which may modify the burn rate properties of the tobacco 10, is positioned in conjunction with the outer wrap tobacco paper 12. As shown, first and second partial inner wrap layers 14a, 14b are provided on opposite sides of the cigarette rack 13. In order to provide substantially equal burn rate properties along the entire cigarette 13, the partial inner wrap strips 14a, 14b extend substantially and are coaxial with the cigarette 13 with respect to the filter 15.

As depicted in the embodiment of FIG. 4, the partial inner wrap layers 14a, 14b extend from end to end of the cigarette 13 and are selectively positioned relative to each other or selectively positioned based on the required burn rate properties. It can be.

3, the partial double wrap cigarette 10 of the present invention alternates between the high diffusion region 21 and the low diffusion region 22 by disposing the inner wrap layer or strips 14a and 14b. It can be seen that. As can be seen, at least one or more high diffusion regions 21 are considered to improve the transmission of carbon monoxide (CO) and oxygen gas through the barrier formed by the outer wrap 12 while maintaining typical emissions. In addition, the low diffusion region 22, which is defined by the degree of enclosing of each partial inner wrap layer 14a, 14b, is potentially coupled with the outer wrap layer 12 to directly influence the porosity of the inner wrap layer 14a, 14b. This can block most or all of the incoming and outgoing gas. The region where the high diffusion region 21 and the low diffusion region 22 are straight together is at least 14 cores porosity for the high diffusion regions that are straight together and 8 cores or less for the low diffusion regions that are straight together. Will show porosity.

As shown in the figure, the construction of the cigarette with modified burn rate is the partial double wrap cigarette 10 depicted here, using a standard outer wrap cigarette paper 12 having a width of 27 mm of a normal cigarette. As shown in Figure 2 and Figure 4 of another embodiment, separate partial inner wrap layers 14a, 14b extending substantially along the length of the outer wrap 12 are located along the interior of the outer wrap. Whereas the outer wrap of tobacco paper is a common configuration with general porosity, the partial inner wraps of this embodiment each have a first and second strip 14a, 14b having a width of 4 mm and a porosity of less than 8 Coresta units. Equipped. Thus, the two inner wrap layers or strips 14a, 14b will surround the circumference which is about 8 mm of the partial double wrap cigarette 10 of the present invention, but will extend around the circumference of the cigarette to 15 mm with respect to the dimensions of a typical cigarette. can do. The combination of the partial inner wrap and the outer wrap is made according to the mentioned parameters, such as the porosity of each paper, but the good burn rate properties as well as the limited impact on the nature or taste of the smoke are less than about 75% of the circumference of the outer wrap. , Preferably by incorporating an inner wrap covering up to 60%, more preferably up to 35%. This is a function of the overall cigarette and will depend on the circumference of the outer wrap. However, modifications may be made to achieve equally good results using the inventive features of the present invention, and the description is not to be considered limiting but merely illustrative.

Alternatively, many other configurations can be used to provide tobacco with modified burn rates as mentioned herein. It will be appreciated that a single inner wrap layer or a plurality of inner wrap layers may be provided by modification of the required properties and burn rate. Thus, as mentioned above, a combination of a low porosity inner wrap portion and a high porosity outer wrap portion can be used to provide various desirable linear burn rates. Thus, a typical linear burn rate of 6.0 mm per minute can be reduced based on the combination of porous outer wrap and partial inner wrap strips between other elements as required, and can be reduced to less than 4 mm per minute as needed. This includes the formulation of a single inner wrap strip with low porosity, or an interior with various components, including reconstituted tobacco, low porosity paper, bandcast tobacco, polymer based materials, and other papers or materials. Replacement with a wrap strip. The inner wrap strip may be coated with other materials to modify combustion or create at least one or more low diffusion regions along the cigarette. The paper can be coated with sodium alginate as a combustion reaction inhibitor, for example, to reduce the porosity of the paper, the outer wrap porosity, tobacco packing density, the number of circumferences and strips of the covered inner wrap, the porosity of the inner wrap and other factors By combining them in whole, appropriate properties can be provided to give the cigarette the required burn rate.

As shown in Figures 4-7, various embodiments may be used to create a low porosity zone. As depicted in Figure 4, the open standard outer wrap 12 is in line with a plurality of inner wraps or inner wrap layers 16a, 16b, 16c, 16d. Such strips will be spaced the same distance along the inside of the outer wrap 12 and may be positioned away from edges or seams that are attached to the outer wrap itself within the cigarette maker's garniture while the outer wrap dries. . As depicted, the strips 16a, 16b, 16c, 16d can all be fed into the accessory and incorporated into the interior of the outer wrap adjacent to the cigarette rack. The burn rate is modified to the required level by placing a partial inner wrap strip so that the burn rate is sufficiently reduced to cause a significantly reduced static burn rate or to turn itself off at the required intervals.

As shown in FIG. 5, an inner layer having a non-linear side, indicated by reference 17 as compared to the edge of the outer wrap 12, may be used as a partial inner wrap to create a low porous area. As shown here, the inner wrap layer 17 may have a wavy shape such that disposing a low porosity area changes its position along the axis of the cigarette. Non-linear placement of such low porosity zones may allow the cigarette to be positioned differently during static combustion to ensure that the required static burn rate is achieved regardless of the location of the cigarette.

Another embodiment of a cigarette with modified burn rate of the present invention is shown in FIG. As can be seen, the high diffusion region 21 and the low diffusion region 22 are defined by the addition of a partial double wrap inner wrap layer 18 which encloses a portion of the tobacco 13 inside the outer wrap 12. do. The partial inner wrap layer 18 shown in the figure extends around about half the circumference of the hook 13. However, various different configurations can be used to achieve the appropriate linear burn rate through the mentioned burn rate modification. The partial double wrap inner wrap layer 18 may consist of ordinary tobacco paper having a low porosity of less than 7 Coresta units or tobacco paper coated with a burn rate modification, or usually less than 5 and more preferably 3 Other configurations, such as a bandcast tobacco sheet, with or without additives having a low Coresta unit value below. A second advantage of using a bandcast or reconstituted tobacco sheet is that the coloring of the inner wrap may be similar to the cigarette 13 and not provide a whitish area of hue extending along the low diffusion area 22. . Furthermore, a polymer film or other material can be used as the inner wrap layer 18 of the partial double wrap. In order to achieve an adequate burn rate correction that is required to maintain a linear burn rate at a sufficiently low level, preferably below 4.0 mm per minute, the inner layer of the double wrap of the partial wrap shown in FIG. 6 has a width of 2 mm to 14 mm, or Preferably less than 75% of the circumference of the outer wrap.

As shown in FIG. 7, another embodiment is disclosed in which a plurality of inner wrap strips 19 are used to enclose a cigarette 13 inside the outer wrap 12. A plurality of inner wrap strips 19 can be supplied in an accessory adjacent to the outer wrap 12 to surround the cigarette 13 when formed in the cigarette maker. The plurality of strips 19 consists of low porous tobacco paper which is fed individually to the cigarette maker or to the cigarette maker adjacent to the accessory by a single or multiple strips, and can be cut to an appropriate strip width. As shown in FIG. 7, a plurality of inner wrap strips 19 are used and extend substantially coaxially along the length of the hook 13. Preferably, a plurality of strips 19 extends along the entire length of the cigarette, regardless of the location of the cigarette. By providing a plurality of strips 19 as shown in Fig. 7, it can be seen that the burn rate of the cigarette further modified can be provided.

It can be appreciated that extending the inner wrap layer substantially along the length of the cigarette 13 to be coaxial provides significant advantages over the alternately formed rings perpendicular to the axis of the cigarette 13. These vertical rings, alternating along the length of the cigarette, will provide a non-linear burn rate of the cigarette 13. Thus, in structures with rings surrounding the cigarette, the linear burn rate can vary from a low linear burn rate to a high linear burn rate depending on the porosity of the paper at the point of the ring as opposed to the porosity of the unregulated paper between the rings. do. This non-linear burn rate would not be desirable in practice, since the continuous and continuous burning of cigarettes between rings for a considerable amount of time would not result in a modification of the appropriate burn rate that could be relied upon through the entire cigarette length. In addition, at the point where a low porosity ring is present, the smoker will crank a cigarette as the burning of the cigarette passes through the low porosity ring. At this point, the delivery of the cigarette can be significantly altered to increase carbon monoxide and other compounds provided when the cigarette burns on one of these rings. The inner layer of the partial double wrap of the present invention thus solves these problems by providing a known normal discharge for the full length of the cigarette while modifying the burn rate along the entire length of the coaxial.

In the design of the cigarette 10 in which the burn rate of the present invention is modified, it may be desirable to include an inner wrap layer away from the seam of the outer wrap 12, whether a plurality of strips or a single layer. As is known in cigarette manufacture, the seam 23 shown in FIG. 1 is formed by a maker overlapping the side edge 24 of the outer wrap 12. In typical tobacco production, an adhesive is applied along one of the edges 24 before the outer wrap is folded to form the cigarette 13. During the manufacture of the cigarette 10 with modified burn rate of the present invention, the partial inner wrap layer, to ensure that the outer wrap 12 is properly formed and that the partial inner wrap layer does not interfere with the formation of the adhesive of the cigarette or the outer wrap layer. It is desirable to keep it away from this seam. Thus, as depicted in the embodiment, the partial inner wrap layer has a side edge 24 so that the inner wrap portion does not interfere with the seam of the outer wrap 12 and does not interfere with the formation of a cigarette in the accessory of a typical cigarette maker. It is shown to be located away from it. Therefore, the cigarette with the modified burn rate of the present invention will be carried out in a normal cigarette manufacturing apparatus with only minor modifications to the paper feeder, and therefore modifications are not necessarily required in the accessory. In addition, in any of the embodiments shown herein, the strips may be alternately positioned outside of the tobacco and held on the tobacco leaf by adhesive or other means to form a straight-lined area with high and low porosity cavities. have.

As shown in Fig. 8, a sample structure for producing a cigarette with a modified burn rate described herein is depicted. The paper feed assembly 50 includes two paper sources, an outer wrap bobbin 37, and an inner wrap or inner strip 32. The outer wrap scoop 37 is comprised of tobacco paper of a normal porous outer wrap having a common width of varying widths between 19 mm and 27 mm as in the usual case, and manufactures tobacco through a plurality of rollers and tensioner guides. Can be supplied to the device. In the illustrated embodiment, the partial inner wrap and outer wrap layers may be combined such that the outer wrap and inner wrap layer form a combined tobacco paper 36 that receives the tobacco in the accessory. The outer wrap layer 30 will be underneath the partial inner wrap strips 34, 35 which are supplied from an array 32 or other source of inner wrap strips. The slab 32 of the inner wrap strip may be narrower than the outer wrap because it is intended to cover only a portion of the inner surface of the outer wrap 30. Prior to forming the combined tobacco paper 36 immediately preceding the accessory, the chamfer 32 of the inner wrap strip can be unwound and fed through a roller and cut into the required strips with a knife. The strips 34, 35 forming the inner wrap portion of the tobacco of the present invention may have significantly different burn rate properties than the outer wrap 30. Thus, by supplying a double dustbin to the mechanism of the present embodiment, the porosity, contents, and other properties can be modified. A slitter 33 may be provided to cut the inner wrap paper into two or more strips.

As shown in Fig. 8, the rim 32 of the inner wrap strip may have paper having a width of 4 mm to 15 mm cut into slits into two strips. The exact combination of the porosity and combustion characteristics of the inner wrap and outer wrap layers can be adjusted to result in a modification of the appropriate burn rate desirable to produce a normal linear burn rate throughout the cigarette and tobacco.

As shown in FIG. 8, the disclosed paper feed assembly 50 provides a plurality of tensioner rollers that properly feed the outer wrap 30 and the partial inner wrap strips 34, 35 to produce a combined tobacco leaf paper 36. It includes. It will be appreciated that the narrower swab 32 causes even more problems when feeding the slit-formed paper into the accessory. Appropriate tension should be applied to the strips 34 and 35 to prevent the inner wrap strips 34 and 35 from tearing prior to the accessory. Furthermore, since the tobacco manufacturing process is processed in the form of a little stop and then thin, it is necessary to properly tension the outer wrap rim 37 and the rim 32 of the inner lap strip. Thus, the partial inner wrap strips 34 and 35 may be combined with the outer wrap paper 30 prior to the attachment, or slits may be formed to provide a suitable tension and join the two layers as shown in FIG. After tearing, they can be joined immediately.

9, there is shown a cross section of an accessory in a cigarette maker. There is usually a belt between the outer wrap 30 and the accessory 40, which is not shown here for purposes of illustration. As shown, the attachment 40 has a bend to form a cigarette and tobacco. The curved portion folds the outer wrap 30 to surround the cigarette after the cigarette is accumulated by the cigarette feeder 41 in the cigarette maker. Prior to entering the accessory, the inner wrap strips 34 and 35 are coupled to the outer wrap 30 so that the combined tobacco leaves 36 are folded and formed into tobacco while the structure of the tobacco leaves is in place. This structure allows for flexibility in combining the various properties of the outer wrap layer and the partial inner wrap layer. Another advantage of tandem formation and processing of tobacco with modified burn rates is that it is an online method that does not affect the rate or formation of actual tobacco. Thus, in the accessory, there are no significant changes required to form a tobacco rod that has been cut to a suitable length and then attached to the filter at a later stage in the cigarette maker.

As shown in Figure 9, the inner wrap strips 34, 35 are supplied to the accessory on the inner surface of the outer wrap 30 so that the cigarette maker is properly positioned when forming a cigarette and a cigarette. In this embodiment, as shown in FIG. 3, the inner wrap strips 34, 35 are located at 90 ° from the seam of the outer wrap 30, and are identical to each other to provide a smooth and continuous burn rate to the cigarette. It is located in the distance. The material of the inner wrap may preferably be located on the inner surface of the outer wrap 30 without adhesive, although materials that hold other positions may be used. Forming tobacco in the accessory 40 and filling the tobacco in the tobacco rod maintain the placement of the inner wrap strips 34, 35.

10, another embodiment of a boil feed assembly 82 is shown. In this embodiment, the outer wrap 12 is fed from its normal position to a bullet roller 82 which sends tobacco leaves to the attachment 60 for forming a cigarette. In this case, the outer wrap 12 is a normal 27 mm wide tobacco paper and has general porosity as well as other common adhesives. As depicted, the combined partial double wrap 36, which can be joined prior to the accessory, is formed from a combination of the outer wrap 12 and the inner wrap strips 34, 35 of the double line.

As can be seen, the inner wrap strip paper 32 from the mower is fed to the guide roller 58 before being cut by the rotary cutter 51 or torn to form a slit. The rotary cutter may consist of a rotary knife 52 or knife block 53. In this structure, it is desirable to have an 8 mm wide bonded portion of the interior of the cigarette, and an inner wrap 32 is provided which is slit cut while forming strips 34, 35 of equally half in width. These strips may be formed by the rotary cutter 51 and split by the split rollers 55, 56 before the partial inner wrap strips 34, 35 join the outer wrap paper 12 on the rollers 57. Can be. Of course, the inner wrap 32 can be cut into narrower strips to overlap the outer wrap.

An advantage of this structure is that the rotary cutter 51 can be provided to cut the paper to the required width. Care should be taken to prevent tearing of the inner wrap paper 32 and each of the strips 34 and 35 after the narrower strip has been formed, thus requiring a narrower strip that requires a guide roller and a tensioning roller. This is a problem when dealing with. Thus, it would be advantageous to provide the rotary cutter 51 at or near the attachment 60 to avoid significant manipulation of the narrow inner wrap strips 34, 35.

In the paper feed assembly 82 shown in FIG. 10, the rotary cutter 51 is shown to form strips 34, 35 from the original web material 32. Numerous other cutting devices or slits, such as static knives, lasers, rotary knives as shown, water jet cutters, kiss cuttings, or fine perforations, can be used in all these embodiments. Furthermore, a preformed web material may be provided, which web material is precut and formed into individual strips, which strips may be separated prior to feeding into the accessory through various processing devices. Numerous different embodiments can be used to provide a suitable inner wrap strip into the accessory in combination with an outer wrap. While the various embodiments disclosed herein teach a particular structure for supplying the inner wrap strip to the accessory, numerous embodiments may be provided for forming or supplying the inner wrap to the accessory in combination with the outer wrap. Such variations are believed to be within the scope of the teachings of the present application, and need not be contemplated of any unnecessary limitations from the specific embodiments of the paper feed assembly mentioned herein.

As disclosed in FIG. 11, a further embodiment 84 is provided in which the cigarette maker 74 includes external mower devices 70, 71. The external dustbin device 70 may be provided with a dustpan 30 of an lain first material for supplying an external wrap paper supplied to the accessory device 77. The mole 30 provides a web material 12 that is fed to the accessory and engages with the web material 32 forming an inner wrap strip. The external dusting device 71 may have a dust of the second material 32 supplied to the cutting device 75 for slit cutting. A slit former or cutting device 75 is positioned in direct contact with the accessory 77 to reduce the operating length of each narrow inner wrap strip. As shown, the maker 74 is an accessory driven by an accessory 77 and a drive shaft 73 for supplying paper and tobacco material during the cigarette formation process so that the cigarette and tobacco are formed with an internal wrap strip formed therein. The apparatus belt 78 is provided.

It will be appreciated that the provision of the outer dusting device 70, 71 for the outer wrap and inner wrap material allows for easier on-line processing of the paper and partial integration of the inner wrap strip into the cigarette maker 74. will be. Furthermore, since the moles can be spaced apart from the manufacturer 74 and no significant change is required in the area around the attachment 77 away from the guide and tension rollers, the outer wrap mould 30 The external arrangement of the inner wrap alley 32 requires minimal structural changes to the cigarettemaker 74. In addition, an external dustbin device can be implemented with current cigarettemakers and can be provided to combine the outer and partial inner wrap strips of the present invention to produce the required burn rate modification.

In use, the external device 71 may be equipped with a band-cast bobbin instead of a common mole of tobacco leaves. The bobbin may be used because of the nonuniformity of the material in the bandcast. A bobbin with a bandcast inspection can be used, where the material is 8 mm wide and fed into the manufacturer 74 through the guide rollers to minimize movement of the bandcast material when the bobbin is unwound. The material can be slit immediately before joining with the outer wrap material in the bullet roller, which is the roller generally found at the beginning of the accessory, ie at the beginning. A plurality of guide rollers and tension rollers may be provided to appropriately supply the material to the accessory to bond the material with the outer wrap material.

Cigarettes with a modified burn rate of the present invention in which the properties of the outer wrap and the inner wrap paper have been altered can be designed. As described above, the structure of a general outer wrap is a structure in which a normal outer wrap has a pore that has a linear spread of 27 mm and has a Coresta unit between 15 and 80. As is generally understood, significantly reducing the porosity of the outer wrap changes the emissions and linear burn rate of the cigarette. Modifying the standard burn rate of a typical cigarette may be achieved by adding a partial inner wrap to the cigarette. The partial inner wrap may be a single inner wrap portion or may be a plurality of inner wrap strips as shown in the various figures. Partial inner wraps may have paper properties with markedly reduced porosity such that the inner wrap paper exhibits porosity of less than 8 Coresta units. If a single inner wrap strip is used, such as a band cast or other paper previously described and shown in Figure 6, the inner wrap layer will have a width of 2-15 mm. The porosity of the inner wrap layer can be modified from any of 0 to 8 Coresta units.

Using the techniques and configurations of the present invention described herein, embodiments of some products have been practiced using configurations of partial strip wraps or partial inner wrap tobacco. In the examples, a control cigarette was used that did not have a partial inner wrap strip showing a linear burn rate between 4.3 and 4.7 mm / min. As described in the chart below, for partial inner wrap strips, different materials were used, ranging from normal treated paper to bandcast tobacco material.

Table 3

In the examples presented, it can be seen that the addition of a partial inner wrap to the tobacco clearly affected the linear burn rate and self-extinguishing compared to the tobacco of the control standard. The linear burn rate for tobacco using the present invention is directly affected, demonstrating that the linear burn rate is reduced by 40 percent. If an inner wrap strip having a width of at least 4 mm is used, the test sample leads to at least 90% self extinguishing. High self-extinguishing rates are achieved with a plurality of 4 mm or more bandcast tobacco material, but using a lower weight paper such as regular tobacco paper does not always appear to provide a high level of self-extinguishing. Narrower strips have different results, which can be corrected by using other additives or by increasing the number of strips. Reference to the self-extinguishing of tobacco in ten layers relates to the NIST test for flammability.

In embodiments where the inner wrap strip consists of heavy weight paper, the position of the second bale of the inner wrap material is an important issue. Due to the lower linear ability to wind a single narrow strip of thicker material onto the moul, the moul will be significantly heavier and wider than the single layer moulder of a typical 27 mm wide outer wrap. Inner wrap wraps of increased size and weight for use online at high speeds, preferably oversize inner wrap wraps, such as the common double wrap cigarette makers known, are not located directly in the cigarette maker in the current paper position. For example, if a heavy weight paper is used, such as a bandcast tobacco sheet for an inner wrap strip having a weight of at least 70 grams per square meter (grams per square meter) and 0 cores, a single layer strip It is not practical to wrap this material in the air. While covering such a material onto a monolayer mole, even over 1,500 to 3,000 linear feet of the material, the single layer strip mole becomes unstable. Due to the narrow width, the moul is likely to be released by some transverse force at the outer edge of the wound material. One solution is to wrap the narrow strip material in a horizontally rolled spool or spool 92 as shown in FIG. 12 so that the loosened strip moves back and forth along the central axis of the spool by unwinding the material. Positioning this wider and heavier transversely rolled spool or spool is problematic for cigarettemakers because of the width of the transversely rolled up, the weight of the trash, and the movement of the unscrewed strips transversely to the cigarettemaker.

As shown in FIG. 12, another embodiment of the unwinding device 90 is shown with the device of the present invention for stabilizing a web of a bobbin of a material 95 wound in an accessory 77. As shown in FIG. The illustrated release device 90 loads a transversely rolled spool or spool 92 onto the accessory and supplies the inner wrap strip web of material 95 to the bullet roller 98 for stable alignment. In addition, as shown in Fig. 12, the supply passage for the first web means a passage for providing the tobacco material 12 from the external dusting device 70 to the accessory device 77, and the supply passage for the second web A passage through which the material 95 is supplied from the release device 90 to the accessory device 77 is meant.

As can be seen, the transversely wound mole 92 is mounted in a cigarette maker and can be released when the cigarette is formed in the cigarette maker at high speed. The hoist 92 wound horizontally will rotate freely in the hub mounted to the release device 90. The narrow inner wrap web of material 95 of about 12 mm or less is unwound from the tufts 92 wound transversely through funnel or ballast 96 across tension bars 94 secured to tension arms 93. . A particular concern when unwinding the transversely rim 92 is to move back and forth across the central axis of the rim 92 when the inner wrap web of material 95 is released. In the embodiment shown in Figures 12 and 13, the release device 90 consists of a support arm, a tension arm 93 and a tension bar 94. The tension arm 93 is mounted and attached to the support arm by a central focal point and can move up and down by the tension of the strip 95 and the tension spring 97a. The tension arm 93 allows the spool to spin more freely and indirectly pulls the web of material in tension, acts as a brake against the spool, and in addition to this tensioning the paper, it also winds up horizontally when the system stops. It prevents the swivel from rotating freely, preventing the scoop from throwing up a large amount of paper when the swivel stops.

When the inner wrap web of material 95 is unwound from the transversely rim 92, the loose web of material 95 moves across the tension bar 94, thus preventing the transverse movement of the loose web of material. The tension bar 94 will be as wide as the tackle 92 to accommodate. Because of the transverse movement of the loose web 95 in reciprocation, the strip must stabilize before feeding into the accessory. Failure to stabilize the inner wrap web of material can cause the strip to tear in incompatible cigarette makers by incompatible tensioning forces. As shown in the figure, a ballast 96 similar to the funnel device of this embodiment allows to move laterally along the top, but inhibits the strip moving laterally at the narrower outlet of the bottom. Upon exiting the funnel or ballast 96, the inner wrap strip extends around the roller 97 in the middle and is fed to the bullet roller 98, having a plurality of intervening rollers depending on the need for proper tension. There is a possibility. Narrow inner wrap web of material 95 into a plurality of narrow strips supplied to the accessory 77 at the inner or upper surface of the outer wrap web of material 12 such that the inner wrap strip is adjacent to the tobacco hook of the cigarette. A slit forming machine or cutter 99 is disposed between the roller 97 and the bullet roller 98 that can cause the cutting to be slit.

As can be seen from the figure, the funnel or stabilizer 96 limits the reciprocating motion of the inner wrap web of the material so that the narrow web is preferably slit into a plurality of strips, preferably up to two, but up to four The web 95 is firmly fixed to be cut. Depending on the required smoking properties of the tobacco produced, the strips will each be between about 3-6 mm.

As mentioned, the release device 90 disclosed herein will be required for several embodiments of heavy inner wrap strip material. With such heavy materials, it has been found that the maximum length of material that can be placed in the swivel to function properly at high speed due to the above mentioned instability is only up to 1,500 feet in a typical monolayer swivel. However, using the transversely woven 92 as disclosed herein, about 6,000 to 120,000 linear feet of material can be accumulated and released for use in an online situation. If a large transverse bobbin is used, an external unwinding motor or drive for use in the unwinding device 92 to simultaneously unwind with the accessory belt 78 and the outer wrap strip 12 opposing the free-rotating hub. You will need to use additional devices. Such an unwinding motor is also necessary to reduce the tension created by attempting to freely rotate a heavy moul without an auxiliary device.

As shown in Figure 13, the tension arm 93 can be rotated around the central axis by the spring 97a so that the tension in the web 95 is not relaxed to cause direct tearing of paper such as material. Further, the ballast 96 may be any device as long as it restricts the lateral movement of the inner wrap strip 95 and need not necessarily be a funnel in the form as shown. Significantly different structure or implementation to provide stability equivalent to the device 96 such that the inner wrap strip 95 is fed to the intermediate roller 97 or directly to the slit former 99 or the bullet roller 98 as needed. An example can be used. Such other alternative structures may be considered within the scope of the overall structure disclosed herein, and modifications to the ballast 96 other than those shown in the figures are contemplated to be within the scope of the teachings herein. For example, the stabilizer 96 may be replaced with a roller that allows the inner wrap strip to rotate 90 degrees such that the transverse movement across the transversely rim 92 can be converted into a rotational motion around the second roller 97 and Therefore, any movement in the longitudinal direction of the axis occurring along the axis of the second roller 97 is prevented.

17 depicts a ballast 110 of another embodiment for use with the present invention. As shown here, the unwinding device 90 for the horizontally wound mole 92 may be coupled with a triangular pan 110 that restricts the tape of the inner wrap web of material 95 from moving laterally. Can be. The ballast or triangular fan 110 shown in FIGS. 17 and 17A, when supplied from a transversely wound shackle 92, houses the inner wrap web at a wider upper end. As pointed out above, while unwinding the horizontally wound mole 92, the inner wrap web of material 95 moves reciprocally across the axis of the mottle 92. The wider top of the stabilizer 110 accommodates this reciprocating lateral movement and restricts such movement at the narrower outlet end so that once the inner wrap strip is in the cigarettemaker and possibly in the middle roller 97 When supplied to a substantial portion of any movement of the inner wrap web of material 95 is removed. As shown, the triangular fan or ballast 110 can be mounted above the attachment area directly below or adjacent to the release device 90. As mentioned, in an effort to stabilize the movement of the transversely wrapped inner wrap web of material 95 so that the application of tensile force by placing the strip 95 in the cigarettemaker and its accessories can be considered normalized and manufactured at high speed. The fan or stabilizer 110 is designed to reduce the amount of lateral movement caused by coupling a transversely rolled mole to the cigarette maker. As shown in Figures 17 and 17A, the triangular fan takes into account the wide inlet area at the top, the width of the inlet area matching the reciprocating transverse movement of the inner wrap web of the material to the bin 92 and the outlet at the bottom. The department attempts to limit the material so that little lateral movement is seen in the cigarette maker. As long as the inner wrap strip 95 passes before entering the cigarette maker or slit former, the fan or stabilizer 110 may be mounted directly to the release device or adjacent to the cigarette maker.

As shown in Figures 14, 15, and 16, additional embodiments may be used for the release device 100 when a larger transverse winding 101 of the inner wrap strip is used. As seen from the configuration diagram of FIG. 14, a larger transversely winding mole 101 is mounted to the hub 106 of the release device 100. The hub may be an electric hub driven by an electric assist device 102 that is indirectly synchronized with the speed of the outer wrap web 12 and the accessory belt 78. This tuning is performed by a photodiode or sensor on a tensioning arm that continuously adjusts the speed of the power assisting device according to the looseness of the web of material and the tension inside. Since the inner wrap web of material is unrolled from the bobbin 101, reciprocation of the inner wrap strip 95 along the shaft's axis is expected. Thus, the material is transferred to a paper turning device or paper turning device 103 having a first roller 105 and a second roller 104 to stabilize the movement of the narrow strip of material 95. Thus, as the loosened strip reciprocates across a large transversely spool or spool of material 101, the reciprocating motion will be transmitted along the first roller 105 and the second roller 104. However, once the inner wrap strip 95 extends to the cigarettemaker and in particular the slit former 99, all lateral movement is eliminated and the narrow inner wrap web of material is stabilized. As shown, the paper switching device 103 completely eliminates the reciprocating motion of the narrower inner wrap web of the material 95 caused by the horizontally unwinding along the bobbin 101, or the reciprocating motion of the roller 97 is used to divert the material 95 in a manner that translates into a rotational motion with respect to 97. Thus, the unrolled inner web of material 95 is rotated about 90 degrees so that the reciprocating lateral movement is transmitted to the reciprocating rotational movement with respect to the roller 97 so that the inner wrap strip can be moved to the bullet roller 98 or the slit former 99. It is preferable to make sure that the position is stable at), and to prevent movement along the axis of the intermediate roller 97.

As can also be seen, the web of material is fed to the slit former 99, before being fed to the bullet roller 98 and combined with the outer wrap paper 12, the web is preferably two strips but more than four possible. A plurality of narrow strips of material can be slitted.

Returning to Fig. 15, the switching device 103 may be composed of a first roller and a second roller extending downward at each X moved from the vertical axis. Each roller can be moved about 45 degrees on the vertical axis. The reciprocating motion of the unwrapped inner wrap strip prior to reaching the diverting device 103 will move along the length of the axis of the hoist 101 which is wound horizontally. As such, for the material to move properly up and down the first roller 105, the first roller 105 needs to be long enough to accommodate this movement. However, it may be expected to stabilize the inner wrap strip 95 sufficiently, so that the paper is stabilized before reaching the slit former 99.

Another embodiment is shown in FIG. 16 in which a single roller 107 is used at each X moved about 45 degrees downward from the vertical axis. The roller 107 causes the narrow strip of material 95 to traverse back and forth, which is caused by the reciprocation of the material unrolled from the molar 101 and also redirects the strip as required. The roller 107 may necessarily be of sufficient length to meet this transverse reciprocating action, but it is not always necessary to be the width of the hoist 101 wound transversely due to the angle of receiving the strip from the mower.

As disclosed in Fig. 16, when a single roller 107 is used, positioning the roller outside of the cigarette maker does not necessarily require the roller to be moved vertically from the cigarette maker as shown in another embodiment. Thus, the narrow inner wrap web of material 95 exiting the diverting device or the diverting device 106 can enter a roller in the middle immediately adjacent to the slit former 99, so that it can be supplied to the bullet roller 98. Can be. An intermediate roller 97 is needed to accommodate the narrow inner wrap web of material prior to entering the slit former 99 to further stabilize the material. This structure will take into account the support and unwinding of a much larger transversely winding 101 which is comparable to or increases in length with the material located in a typical single layer outer wrap array 30.

The horizontally wound claws 101, 92 depicted herein comprise a plurality of separate pieces, each including a spool of bandcast tobacco based material having a width of between 8 mm and 12 mm or less, depending on the number of strips required or other factors. The strip of paper will be fed to the bullet roller 98 immediately adjacent to the outer wrap strip 12. It is contemplated that each inner wrap strip of width 4 mm or less will act as described herein to properly modify the burn rate of the cigarette and also improve the taste of the cigarette or alter the properties of the cigarette in both the main and secondary flows. By using a bandcast material, certain advantages related to self-extinguishing will be realized due to the weight and porosity of the paper. Such bandcast material may comprise about 22% sodium alginate, but may have a content in the range of 7% to 30%. It may also have about 7% to 22% glycerin for proper properties. The horizontally rolled scab may have a diameter of 10, 12, 20 inches or more, depending on the linear needs of the tobacco maker and the manufacturing requirements thereof. As shown in the embodiment for a heavy transverse spool, power assist device coupled to a cigarette maker, a power assist or electric unwinding motor 102 may be used, so the unwinding speed of the lateral spool is And the unwinding speed of the material of the outer wrap 12 supplied to the and the accessory.

While still using the concepts of the present invention, it is evident that changing the porosity between the outer wrap and the inner wrap, the width of the inner wrap, the materials and other elements used in the inner wrap will immediately modify the burn rate of the cigarette. It has been described herein to add a partial inner wrap layer online to adequately modify the burn rate of the cigarette, and such changes are believed to be within the scope of the teachings of the present application.
