Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to smoking articles having a modified flue gas delivery amount. 5 [Prior Art] A smoking article (e.g., a cigarette) includes a roll of smokable material (e.g., grass) that is tightly wrapped in a wrapping paper (cigarette paper). A filter unit comprising 0 - or more filter assemblies may be joined to the wrapped tobacco roll using a tipping paper. For a uniformly composed tobacco roll, the flue gas transmitted from the burning tobacco via the tobacco roll is determined by the following three main factors under any given suction condition: The amount of air that is inhaled (which will depend on the degree of ventilation through the cigarette paper); the filtering of the flue gas through the remaining unburned portion of the tobacco roll; and the burning rate of the tobacco roll between suctions ( Smoulder rate 15 (smoulder rate)). Therefore, the amount of flue gas delivered by any single suction will depend on the length of the remaining tobacco roll, and the standard amount of suction from the end of the tobacco roll will result in a shortening of the tobacco roll. Higher smoke delivery. The filter unit and the structure containing any of the venting means therein (and the venting means that can be placed in the tipping paper) modify the actual flue gas/air combination that is delivered to the smoker. Therefore, the characteristics of the filter unit and the ventilator are typically adjusted to provide different smoking characteristics for different brands of smoking articles in terms of the amount of smoke delivered. However, because the smoke will pass through the unburned portion of the tobacco, the structure of the tobacco roll also plays a role in the delivery of smoke to the smoker. Therefore, modifying the structure of the tobacco roll so that it does not have a uniform composition can be used to further adjust the amount of smoke delivery. 5 SUMMARY OF THE INVENTION Accordingly, a first aspect of the present invention is directed to a smoking article comprising: a grass roll; a wrapper wrapped around the grass roll; and a material patch positioned Between the tobacco roll and the wrapping paper and extending longitudinally along the tobacco roll from an intermediate point of the tobacco roll to the mouth end of the tobacco roll 10, the structure of the material allows the patch to provide The tobacco-to-mouth flue gas path upstream of the patch, which path allows the smoke to flow through less than the path of tobacco passing under the patch. This structure modifies the smoke flow effect compared to an equivalent smoking article without the patch. When the smoker draws the smoking article, the smoke generated from the tobacco portion in the fifteenth portion of the tobacco roll will have a lower resistance path through the smoking article, so that the smoke will be delivered more efficiently. This will change the quality of the smoking experience of a good smoker. The patch also provides an additional effect. Introducing an open structure of material into the smoking article increases the static burning rate of the smoking article above the portion containing the patch. Therefore, the smoker can perform less suction from the second portion of the smoking article, thereby receiving less smoke, and thus having a smaller amount of residue due to consumption of the first portion of the smoking article. The relationship is piled up in the tobacco. The length and position of the patch can be selected to provide a high smoke transfer rate and a low smoke transfer ratio. For example, the patch can extend longitudinally from the midpoint of 2009 38103 5 Ο 10 15 ❹ 20 to the mouth end of the tobacco roll. Alternatively, the patch may extend longitudinally from the intermediate point to a second point between the intermediate point and the mouth end. The second point may be between 1% and 40% of the total length of the tobacco roll from the mouth end. A range of patch lengths may be employed, for example, the patch may extend longitudinally over substantially 10% to 90% of the total length of the tobacco roll, or the patch may extend longitudinally over the total length of the tobacco roll. The essence of the degree is above 40% to 80%. The patch may extend substantially around the entire circumference of the tobacco roll. Alternatively, the patch may include one or more portions of material disposed about the tobacco roll. These practices may be selected to adjust the degree of smoke flow modification produced by the patch. A variety of combustible materials are available for the patch. Any material that provides the necessary low resistance flue gas flow patches is suitable. Materials can be selected based on their structure to help provide a special level of smoke flow resistance. In some embodiments, the patch may comprise a foam material. In other embodiments, the patch may include a creped material that wrinkles substantially longitudinally in the tobacco roll. Wrinkle materials of various structures can be used. For example, the crease material may have a laminated structure comprising a crease layer and a non-wrinkle layer. The non-wrinkle layer can be disposed between the tobacco roll and the crease layer or between the crepe layer and the wrapper. Alternatively, the crease material may have a laminated structure comprising a crease layer sandwiched between two non-wrinkle layers. Alternatively, a wrinkle layer can be used alone without any non-wrinkle layers. In another embodiment, the patch may comprise a embossed material, 5 200938103 having a score extending substantially longitudinally in the tobacco roll; or a grooved material having a substantially longitudinal extension in the tobacco a groove in the roll; sheet material. V ' 5 e 10 15 ❹ 20 The patch may include at least one oxidant to raise the static burning rate of the smoking article over the length including the patch. This can be used to adjust the static burn rate and thus adjust the number of puffs from the back of the smoking article. The patch may have a different color than the wrapping paper and/or the tobacco roll. This allows the patch to be detected by an optical defect detection system, which is sometimes used to provide quality control during the manufacture of the smoking article. The tobacco roll may have a smaller weight per unit length of tobacco under the patch than upstream of the patch. This provides space to accommodate the patch and further enhances the inclusion of the patch in the smoking article. Part of the burning rate of the static bear. Any convenient method can be used to provide the tobacco roll. For example, by trimming the tobacco from the outside of the tobacco roll, or by removing the tobacco ring from the tobacco roll ( Tobacco bead) can be used to trim the grass to produce a smaller weight. The smoking article may further include - a filter, unit attached to the mouth of the grass roll. The fresh element may be wounded - or more Ventilation hole. The second Wei point of the present invention relates to a method for manufacturing a smoking article, which comprises a m-roll; on the roll, a technical patch is placed on the roll, and the sticker is taken along the secret grass roll. The structure of the material extends longitudinally to the mouth end of the grass roll at the intermediate point of the grass roll and the patch is oriented such that the patch provides one from the finished smoking article. 200938103 Upstream tobacco to mouth tobacco a path that causes the resistance of the smoke to flow less than a path through the tobacco below the patch to an intermediate point of the tobacco roll; and wrapping the tobacco roll with a wrapper. The material patch may be included The patch is positioned on the tobacco roll prior to wrapping the tobacco roll 5. Alternatively, providing the material patch may include adhering the patch to the wrapping paper prior to wrapping the tobacco roll with the wrapping paper. The inner surface. _ The method may include: trimming the tobacco from the outside of the tobacco roll over the area where the patch is to be placed, thereby producing a lighter 10 tobacco weight per unit length; and placing the patch in Above the tobacco roll, the patch will cover the area from which the tobacco has been trimmed. Alternatively, the method may include trimming the tobacco from the outside of the tobacco roll over the area where the patch is to be placed, thereby Producing a lighter weight; removing a tobacco roll from the tobacco ring; and placing the patch over the tobacco roll such that the patch covers the area where the tobacco has been trimmed. D [Embodiment] It is an object of the present invention to provide a smoking article, such as a cigarette, that delivers fumes to a smoker 20 with improved efficiency in a first portion of the smoking article, and from all of the remainder of the smoking article The smoke generated in or part of the smoke may be smaller than the conventional smoking article. To solve this problem, the present invention positions a material patch below a portion of the wrapping paper outside the smoking article, as compared to the tobacco in the smoking article. The material patch allows the flue gas to pass more freely. 7 200938103 : kg: according to a method of the embodiment of the present invention, the object includes - in the grass: or in the Zhuo Juan 12, which will be Around the right tenth, the parcel paper will form a wrapper 14 (cigarette paper) having a first end to be ignited; the barrel 14. The second end of the smoking article is Β.

Into @非包包纸14' is arranged to be modified by the volume of 'by the people' and is different from the conventional design. The patch will extend from the mouth end B (this example) to the mouth end.
的-中間點。該貼片在該吸煙物件之::燃之末端Α之間 高的透氣性可讓空氣與煙氣流動(所以，具有J 構的材料所構成或者會被建構成讓』貼片 供開放結構），因此，其會在冒煙期間，為由該吸煙=之 被點燃端所產生且經由該吸煙物件被吸入的煙氣提供一 條路徑，據於通過位於該W上方4草的路徑，該路 徑讓煙氣流動的阻力較小。所以，從該貼片上游的菸 部分處關祕草所產生的煙氣相較於經㈣終草可更 自由地經由該貼片材料通往該口端。 圖2所示的係圖1的簡化形式（其中，為清楚起見已經 略去終草和貼片的陰影部分），用以表示流過該吸煙物件 8 200938103 ίο的煙氣所佔據的路徑。當吸煙者在已點燃的吸煙物件上 抽吸時，因燃燒菸草所產生的煙氣20會依照慣常的方式 通過該菸草捲的第一部分朝口端B傳播。抵達該吸煙物件 中該貼片16之起始處的中間點時，該煙氣會有兩條傳播 5 路徑可用：通過貼片16的第一低阻力路徑22 ;以及通過 菸草12的第二較高阻力路徑24。相較於該菸草路徑，通 過該貼片材料的路徑的障礙較小而且具有很小的過濾效 ©率。阻力差意謂著大部分的煙氣會經由貼片16前進至口 端。所以，相較於沒有貼片的習知菸草捲，來自菸草捲12 10 上游部分的煙氣20會以較小的阻力且更有效地被傳遞至 吸煙者。所以，吸煙者在抽吸該吸煙物件時以較小的氣力 便可以收到相同的煙氣量，甚至在首次抽吸該吸煙物件期 間所產生的煙氣中被傳遞的百分比會高於正常情況。 當該被點燃吸煙物件10的燃線抵達該貼片16時，該 15 貼片的開放結構會提高該吸煙物件的靜態燃燒速率或悶 燒速率（此為吸煙者未抽吸時該吸煙物件的材料被燒掉的 ® 速率）。這會減少可從該吸煙物件之第二部分處（含有該貼 片的部分）進行的抽吸次數，因此從該第二部分處被傳遞至 吸煙者的總煙氣量會小於從沒有貼片的習知吸煙物件處 20 被傳遞的總煙氣量。這非常有利，因為會累積在下游部分 之於草中之來自該吸煙物件之第一上游部分的殘餘物中 較大的數量被燒掉而較少數量會被傳遞至吸煙者。 因該貼片16之開放結構所給定的高燃燒速率可藉由 讓用以製作該貼片的材料具備一或多個助燃劑而被進一 9 200938103 步提高。該些係提高（作為一表面層或是藉由浸潰 (impregnation)來施加）一材料的燃燒速率的物質其施加於 該材料上。助燃劑的數量和類型可依照貼片材料、菸草、 以及包裹紙的類型來選擇，用以提供所期望的燃燒速率。 5 合宜的助燃劑包含檸檬酸鹽，例如獰檬酸鈉或檸檬酸鉀。 亦可使用熟習本技術的人士已知的任何助燃劑/添加劑作 為燃燒速率添加劑，例如鈉鹽或卸鹽、醋酸鹽與酒石酸 鹽、磷酸一銨、磷酸氫二鈉、檸檬酸鈉與檸檬酸鉀、以及 醋酸鈉。 10 所以，大體言之，相較於不具有貼片的等效吸煙物 件，一具備根據本發明之貼片的吸煙物件從該菸草捲的第 一部分處會具有增高的煙氣傳遞量而從該菸草捲的第二 部分處會具有降低的煙氣傳遞量。 圖1與2顯示一從該吸煙物件的口端B實質延伸至該 15 菸草捲12之中點的貼片16。不過，本發明並未受限，並 且可以使用其它長度的貼片。該長度可經過篩選用以選擇 @ 介於增高的煙氣傳遞量之部分和降低的煙氣傳遞量之部 分之間的任何所期望的比例。經發現，可以使用介於該菸 草捲之總長度的10%與90%之間的長度，舉例來說，介於 2〇 範圍40%至80%中的長度。 另外，該貼片並不需要一直延伸至該吸煙物件的口 端。終止在不及該口端處的貼片，仍會提供上述從該貼片 上游部分處具有高煙氣傳遞量，以及從包含該貼片的部分 處具有低煙氣傳遞量的效果。該貼片下游的剩餘部分提供 200938103 的煙氣傳遞量則與不具有貼片的習知吸煙物件相當。該貼 片與口端之間的間距可經過篩選，用以在三種類型的煙氣 傳遞量之間提供所期望的總體平衡。舉例來說，該貼片可 從該菸草的一中間上游點延伸至與該口端相隔介於該菸 5 草捲總長度範圍1%至40%中的某一點。 為針對一給定長度的貼片提供最大的煙氣傳遞量修 改效果，該貼片應該延伸在該菸草捲的整個周圍。 圖3所示的係圖1的吸煙物件10沿著直線X-X的橫 向剖面圖。於該範例中，貼片16完全圍住菸草捲12。請 10 注意，在貼片16和包裹紙14之間雖然顯示一間隙，但這 僅係為清楚起見；包裹紙14通常會接觸貼片16。 藉由使用一並未整個延伸圍繞該菸草捲12的貼片 16，便可進一步改變煙氣傳遞量修改結果。於此實施例 中，貼片16包括一或多個分離部分的貼片材料。對一個 15 以上部分來說，該等部分會被分隔設置在該菸草捲12的 周圍上。為均勻燃燒該吸煙物件，該等部分可對稱分隔設 Θ 置在該周圍上。 圖4所示的係吸煙物件10的橫向剖面圖，其中，貼 片16包括三個個別部分26,它們係在該包裹紙14下方被 2〇 均勻地定位在該於草捲12周圍上。 該貼片可以具有適當燃燒與組成特性的任何材料來 製作，用以納入一吸煙物件中並且為煙氣傳播提供必要的 低阻力通道。可以使用本質上具有所期望之結構的材料， 例如具有充分開放結構的纖維薄片材料。該纖維薄片材料 11 200938103 可能係纖維素薄片材料或是含菸草的薄片材料，例如再生 菸草薄片材料或菸草替代薄片材料。或者，材料可經過特 別製作而具有合宜的開放結構。 舉例來說，可以使用泡珠材料，其中，在發泡過程中 5 所形成的氣泡會提供一開放結構並且為煙氣提供一實質 自由路徑。合宜泡沫材料的範例為擠壓菸草再生材料以及 泡沫帶鑄菸草薄片。 _ 圖5所示的係一吸煙物件10的部分縱向剖面圖，其 5 中，貼片16包括一泡沫材料。 10 於其它實施例中，該貼片可能包括有皺摺的材料，例 如有皺摺的紙或硬紙板。藉由將該材料中的皺摺或是凸脊 /凹槽(ridges/troughs)排列成縱向佈設在該於草捲中，便會 在該菸草捲的周圍提供複數個平行縱向的開放通道。有數 種有皺摺材料配置可以使用。 15 圖6A所示的係有皺摺材料30的第一範例的側面圖。 材料30具有層疊結構並且包括一被夾設在一外側平坦非 Θ 皺摺層34和一内侧平坦非皺摺層36之間的皺摺層32。該 等皺摺的末端會被黏著至該等平垣層，用以形成一複合層 疊。該等各層可能係由相同或不同的材料所製成。 20 圖6B所示的係吸煙物件10的橫向剖面圖，其具有由 圖6A的有皺摺材料30所製成的貼片16。外侧平坦層34 會被包裹紙14包住且菸草捲12會接觸内側平坦層36。第

The patch has a high gas permeability between the end of the smoking article: the end of the burning, allowing the air and the flue gas to flow (so, the material having the J-structure or being constructed to make the patch for the open structure) Therefore, it will provide a path for the flue gas generated by the smoking end and which is inhaled via the smoking article during the smoking period, according to the path of the grass located above the W, which allows The resistance to smoke flow is small. Therefore, the smoke gas generated from the tobacco portion upstream of the patch can be more freely passed through the patch material to the mouth end than the (4) terminal grass. Figure 2 is a simplified version of Figure 1 (where the shaded portions of the final grass and patch have been omitted for clarity) to indicate the path occupied by the smoke flowing through the smoking article 8 200938103 ίο. When a smoker smokes on a ignited smoking article, the smoke 20 produced by the burning of the tobacco propagates through the first portion of the tobacco roll toward the mouth B in a conventional manner. Upon reaching an intermediate point in the smoking article at the beginning of the patch 16, the smoke will have two propagation paths available: a first low resistance path 22 through the patch 16; and a second comparison through the tobacco 12 High resistance path 24. The path through the patch material is less obstructive and has a small filtration efficiency compared to the tobacco path. The difference in resistance means that most of the fumes will advance through the patch 16 to the mouth. Therefore, the flue gas 20 from the upstream portion of the tobacco roll 12 10 will be delivered to the smoker with less resistance and more effectively than the conventional tobacco roll without the patch. Therefore, the smoker can receive the same amount of smoke with less force when sucking the smoking object, and even the percentage of the smoke generated during the first suction of the smoking article will be higher than normal. . When the wicking of the ignited smoking article 10 reaches the patch 16, the open configuration of the 15 patch increases the static burning rate or smoldering rate of the smoking article (this is the smoking article when the smoker is not pumping) The rate at which the material is burned off). This reduces the number of puffs that can be taken from the second portion of the smoking article (the portion containing the patch), so the total amount of smoke delivered to the smoker from the second portion will be less than the amount of the patch that has never been patched. The amount of total smoke delivered by the conventional smoking article 20 is. This is very advantageous because a larger amount of residue from the first upstream portion of the smoking article that accumulates in the downstream portion of the grass is burned off and a smaller amount is delivered to the smoker. The high burn rate given by the open structure of the patch 16 can be increased by providing the material used to make the patch with one or more oxidizers. The materials are applied to the material as a surface layer or by impregnation to apply a rate of burning of a material. The amount and type of oxidizer can be selected in accordance with the type of patch material, tobacco, and wrapping paper to provide the desired rate of burning. 5 A suitable combustion improver comprises a citrate such as sodium citrate or potassium citrate. Any combustion improver/additive known to those skilled in the art can also be used as a burn rate additive, such as sodium or salt stripping, acetate and tartrate, monoammonium phosphate, disodium hydrogen phosphate, sodium citrate and potassium citrate. And sodium acetate. 10 Therefore, in general, a smoking article having a patch according to the present invention will have an increased amount of smoke transfer from the first portion of the tobacco roll compared to an equivalent smoking article that does not have a patch. There will be a reduced amount of smoke transfer at the second portion of the tobacco roll. 1 and 2 show a patch 16 extending substantially from the mouth end B of the smoking article to a point in the 15 tobacco roll 12. However, the invention is not limited and other length patches can be used. The length can be screened to select @ between any portion of the increased flue gas delivery amount and a portion of the reduced flue gas delivery amount. It has been found that a length between 10% and 90% of the total length of the tobacco roll can be used, for example, a length between 40% and 80% in the range of 2〇. Additionally, the patch does not need to extend all the way to the mouth of the smoking article. Terminating the patch that is not at the end of the mouth will still provide the above-described effect of having a high flue gas transfer from the upstream portion of the patch and a low flue gas transfer from the portion containing the patch. The remainder of the downstream of the patch provides 200940103 with a smoke delivery equivalent to a conventional smoking article without a patch. The spacing between the patch and the mouth can be screened to provide the desired overall balance between the three types of smoke delivery. For example, the patch can extend from an intermediate upstream point of the tobacco to a point spaced from the mouth end by between 1% and 40% of the total length of the tobacco roll. To provide maximum smoke delivery modification for a given length of patch, the patch should extend throughout the circumference of the tobacco roll. Figure 3 is a transverse cross-sectional view of the smoking article 10 of Figure 1 taken along line X-X. In this example, the patch 16 completely encloses the tobacco roll 12. Please note that although a gap is shown between the patch 16 and the wrapper 14, this is for clarity only; the wrapper 14 typically contacts the patch 16. The smoke delivery amount modification result can be further changed by using a patch 16 that does not extend entirely around the tobacco roll 12. In this embodiment, patch 16 includes one or more discrete portions of the patch material. For a portion of 15 or more, the portions are spaced apart around the tobacco roll 12. To evenly burn the smoking article, the portions are symmetrically spaced apart on the periphery. A cross-sectional view of the smoking article 10 shown in Figure 4, wherein the patch 16 includes three individual portions 26 that are evenly positioned 2x around the wrapping paper 14 around the grass roll 12. The patch can be made of any material with suitable combustion and composition characteristics to be incorporated into a smoking article and provide the necessary low resistance channels for smoke propagation. A material having a desired structure in nature, such as a fibrous sheet material having a sufficiently open structure, can be used. The fibrous sheet material 11 200938103 may be a cellulose sheet material or a tobacco-containing sheet material such as a reconstituted tobacco sheet material or a tobacco substitute sheet material. Alternatively, the material can be specially made to have a suitable open structure. For example, a bead material can be used in which the bubbles formed during the foaming process provide an open structure and provide a substantial free path for the flue gas. Examples of suitable foam materials are extruded tobacco reconstituted materials and foam tape cast tobacco flakes. Figure 5 is a partial longitudinal cross-sectional view of a smoking article 10, wherein the patch 16 includes a foam material. In other embodiments, the patch may include creased material such as creased paper or cardboard. By arranging the creases or ridges/troughs in the material longitudinally in the grass roll, a plurality of parallel longitudinal open channels are provided around the tobacco roll. There are several wrinkle material configurations available. 15 is a side view of the first example of the crease material 30 shown in FIG. 6A. The material 30 has a laminated structure and includes a crease layer 32 sandwiched between an outer flat non-creped layer 34 and an inner flat non-corrugated layer 36. The ends of the wrinkles are adhered to the flat layers to form a composite laminate. The layers may be made of the same or different materials. 20 is a transverse cross-sectional view of the smoking article 10 of Figure 6B having a patch 16 made of the creased material 30 of Figure 6A. The outer flat layer 34 will be wrapped by the wrapping paper 14 and the tobacco roll 12 will contact the inner flat layer 36. A first group of flue gas channels are defined between the inner flat layer 36 and the wrinkle layer 32, and a second group of flue gas channels are defined between the wrinkle layer 32 and the outer 12 200938103 side flat layer 34 between. A side view of a second example of a wrinkle material 38 is shown in Figure 7A. In this case, the creased material includes only a crease layer 32 and an inner flat layer 36. 5 is a transverse cross-sectional view of the smoking article 10 shown in Figure 7B using the patch material 38 of Figure 7A. There is no outer layer 34 in Figure 6A, so. The crease layer 32 will contact the wrapper 14. The overall structure is equivalent to FIG. 6B, and the second group of flue gas channels are defined between the wrinkle layer 32 and the wrapper 14, rather than being defined between the wrinkle layer 32 and the outer flat layer 34. Between 1 。. This alternative arrangement uses less material, however, it has been found that structural toughness may be less than the embodiment of Figure 6B due to the open space relationship directly beneath the wrapper 14. In addition, the rate of combustion will vary due to the small amount of material. A side view of a third example of a crease material 40, shown in FIG. 8A, includes a crease layer 32 and an outer flat layer 34. This is the same as the wrinkle material 38 of Figure 7A after being turned upside down, however, providing an outer flat layer to take the inner flat layer provides a different structure for the final smoking article. A transverse cross-sectional view of the smoking article 10 of Figure 8B, including the creased patch material 40 of Figure 8A. The outer flat layer 34 will contact the wrapper 20 14, and a group of flue gas channels will be defined between the outer flat layer 34 and the wrinkle layer 32. However, the absence of the inner layer (e.g., the inner layer in Figures 6B and 7B) indicates that no additional flue gas channels are defined on the inner side of the wrinkle layer 32. Instead, the groove on the side of the wrinkle layer will be filled with tobacco 12. This configuration will result in an increase in the amount of flue gas delivered from the upstream portion of the grass roll 13 200938103 which is smaller than the embodiment of Figures 6B and 7β and will also provide different combustion rates. Therefore, the structure of the patch material can be screened to adjust the modification of the smoke delivery amount caused by the presence of the patch. Figure 9A is a side elevational view of a fourth example of a wrinkle material 42 that includes only a layer of -10, without a (10) or (four) flat layer. Figure 9A is a transverse cross-sectional view of a smoking article 1 , having a patch composed of a hostile material of Figure _9Α. It will achieve the same structure as that provided by the corrugated material 4〇 of Fig. 8Β, which is only outside the wrinkle layer 32 (in this case, it is composed of the wrinkle layer 32 and the wrap 10 The paper 14 defines a groove in which the grass 12 is located inside the crease layer 32. It uses less material to produce the same structure, but is the same as the embodiment of Fig. 7B' because there is no outer flat layer below the wrapping paper 14. Therefore, the outer toughness of the smoking article may decrease. It is possible to use a sticker 15# material which has a similar structure to the creped material, for example, a pair of parallel ribs extending therebetween When the patch is applied to the tobacco roll, the ribs are longitudinally disposed in the length of the tobacco roll and radially extend between the two flat layers. The term "material" means a patch material that includes the same structure for providing a plurality of longitudinal flue gas paths. "2" or "The patch may use a embossed material having a --scratch pattern, and the scribes will Being embossed on its surface and being positioned at the suction The objects 'are arranged to provide a road grip along the length of the patch. The scores can be straight and straight and will be aligned "parallel to the length of the tobacco roll, thereby providing - substantially equivalent The 200938103 structure with enemy patches on one side. Alternatively, the indentations may be curved or straight but arranged to form an angle with the length of the hail. These configurations provide The flue gas path is longer than the longitudinal extent of the patch, which can be used to further modify the amount of flue gas delivered from the tobacco upstream of the patch. 5 Aligning the grooves to the upstream of the patch by using a grooved material The flue gas provides a path that achieves the same effect as a embossed material. The patch can be colored 'to help identify the defect detection system commonly used during the manufacture of smoking articles to confirm one or more A completed or partially completed smoking object of a defective or defective component. Such detection 10 systems may be optical systems that monitor the number of light transmitted or reflected by one or more wavelengths by various components. Therefore, if the color of the patch is different from tobacco and/or wrapping paper, then an optical detection system can be used to determine whether the patch is present in the finished smoking article. The gas delivery provides a practical modification of 15 degrees. The thickness of the patch will be much larger than the typical thickness of a standard wrapping paper (cigarette paper). For example, the thickness of the patch may be between the thickness of the wrapping paper. Between 5 and 50. This corresponds to a patch having a thickness substantially in the range of 111. 2111111 to 2 mm. During the manufacture of the smoking article, the patch may be positioned in the tobacco prior to application to the wrapping paper. Around the roll; or, 20 the patch can be adhered to the wrapping paper before wrapping the paper roll (in a manner similar to the technique described in WO 2005/082180 for wrapping paper in a smoking article) An adsorbent material and a perfume mesh layer are provided below. In either case, the grass below the patch will be squeezed to achieve a substantially constant diameter over the length of the smoking article. Therefore, the tobacco concentration in the section 200938103 upstream of the final grass roll will be less than the tobacco in the downstream part of the tobacco roll. This further affects the relative resistance of the tobacco to the patch for flue gas flow and affects the static burning rate of the second portion of the smoking article. To address these additional effects, according to another embodiment, it is proposed to reduce the width of the tobacco roll underneath the patch such that the weight of the tobacco per unit length below the patch is less than the upstream of the patch. This can be achieved by removing some of the tobacco from the tobacco roll, for example, by using one or more trimmers (ecreteur) discs (e.g., in smoking articles in the prior art) 10 A disc for sizing, shaping, and trimming a tobacco ring. A portion of the tobacco is cut from a continuous tobacco ring from which the tobacco roll is to be cut. Figure 10 is a side elevational view of the tobacco roll 12 that has been shaped in this manner. One end of the tobacco roll 12 (designated as the upstream end 15 A of the smoking article) has a diameter a, and the other end of the tobacco roll 12 (designated as the downstream end B of the smoking article) has a smaller diameter b. The difference between the diameters is substantially the same as the thickness of the material forming the patch. Therefore, when the patch is positioned around the smaller diameter portion of the tobacco roll, the combination of the tobacco roll and the patch will There is a substantially uniform diameter. This will give the final smoking article a flat outer surface and a constant tobacco density. To this end, the smoking articles described herein have included tobacco rolls, wrappers, and patches to provide unfiltered smoking articles. In this case, a color or other distinguishing mark or feature pattern may be applied to the outside of the wrapper at the mouth end of the final smoking article to help the consumer correctly recite the end before smoking. Alternatively, the grass roll may have an over-twisting unit for providing a cutting-edge filter (four) smoking article in a conventional manner, wherein a filter unit is joined to the mouth end of a wrapped tobacco roll by a tipping paper. . The filter unit may have any configuration, including single or multiple components, and may or may not be equipped with ventilation means/, for example by on-line laser processing or by pre-perforation. A surrounding vent column or zone is provided. Accordingly, the term "smoking article" as used herein is intended to include: a non-filtered smoking article comprising a tobacco roll without a filter unit; a smoking article with a filter attached to the tip, including an attached filter unit a tobacco roll; and a grass roll without a filter, but a filter unit can be attached thereto by a later stage of production to form a smoking article with a tip attached to the filter. A longitudinal 15 side view of a smoking article with a filter attached to the tip, including the tobacco roll 12, wrapper 14, and patch 16 shown in Figure 1, coupled to the tobacco roll by a tipping paper 46 With a filter unit 44, the tipping paper 46 will surround the filter unit 44 and overlap the end of the tobacco roll 12 over the wrapper 14 in a known manner. The filter unit 44 has a venting means in the form of a row of front perforations 20 48 formed in the tipping paper 46. The term "r-tobacco" as used herein is understood to include a material that can emit smoke. Generally, it includes tobacco materials (eg, tobacco stems, lamina, grass dust, silk, and Expanded Tobacco Regenerated Tobacco, and Tobacco Substitute Materials. 17 200938103 [Simple Description of the Drawings] To better understand the present invention and how to practice the present invention, the following figures have been referred to by way of example, wherein: A longitudinal sectional view of a smoking article according to an embodiment of the present invention; FIG. 2 is a simplified form of FIG. 1 for indicating smoke flowing through the smoking article; FIG. 3 is a view according to the present invention.
