Description

[0001] Apparatus and method for use in the production of rod-shaped articles [

The present invention relates to an apparatus and a method for use in the production of rod-shaped articles. The bar-shaped article may be, for example, a smoking article.

For example, it is known to decorate rod-shaped articles such as smoking articles, for example, by printing or embossing or other decorations, to identify the brand or source of the rod-shaped article. In order to influence the fluid dynamics of smoke, it is also known to create openings in a cigarette packaging material, for example a tipping paper. It is also known to create, for example, transparent portions that allow the interior of the filter to be viewed from the outside.

There is a need to provide a method and apparatus that allows high-speed production of such bar-shaped articles.

According to an aspect of the present invention, there is provided an apparatus for use in the production of bar-shaped articles. The apparatus includes a supply unit for providing sheet material. The apparatus further comprises a cutting unit for cutting the cutout piece from the sheet material provided by the feeding unit to produce a corresponding cutout area in the sheet material. The apparatus also includes a positioning unit for positioning the sheet material at the cut position, wherein the cut-out piece is cut from the sheet material. The sensing unit, which operates in conjunction with the positioning unit, is provided to determine the cutting position so that the bar-shaped article and the cut-out area can be matched. The apparatus further comprises a removal device for removing the cut-out piece . The apparatus also includes a wrapping unit for receiving the sheet material including the cut-out area and wrapping around the at least a portion of the bar-shaped article, the sheet material including the cut-out area.

The feeding unit may comprise, for example, a bobbin, wherein the sheet material is stored and the sheet material can be unwound with the aid of proper driving. However, any other kind of supply unit may be used.

The cutting unit makes it possible to produce a cut-out region of the sheet material on-line during the manufacture of the bar-shaped article. In the context of the art, when pre-cut sheet material is used for bobbins, damage may occur during winding and unwinding of the pre-cut sheet material from the bobbin or during transport of such pre-cut material of the production apparatus, The cutout area of the material may reduce the structural strength of the sheet material. According to the invention, advantageously, the cut-out region is produced in-line. Thus, the risk of damage to the sheet material having the cutout area during production is significantly reduced.

The positioning unit enables the placement of the sheet material at the cutting position where the cutout pieces are cut from the sheet material. The positioning unit enables accurate positioning of the sheet material in the cutting unit in which the cutout piece is cut out, so that the cutout area is precisely generated at a desired position of the sheet material. Thus, according to the present invention, it is advantageously possible to precisely locate the cut-out area with respect to the required length of the filter wrapping paper or tipping paper and the corresponding distance between the subsequent cut-out areas.

The sensing unit, which operates in conjunction with the positioning unit, allows the cutting position to be determined, thereby matching the bar-shaped article with the cut-out area. Also, precise positioning of the cut-out area of the sheet material allows the cut-out area to match features or objects further down the production line, such as rod-shaped articles.

By aligning the bar-shaped article with the cut-out area, precise positioning, sensory effects of the cut-out area may be created or influenced with respect to the length of the bar-shaped article, e.g. . For example, a logo-shaped cutout area may be made visible by overlapping the bottom bar-shaped article and the cutout logo. For example, the cut-out region may create a window in the bar-shaped article, e.g., allowing viewing of the filter. Such a window may be matched to the objects contained in the bar-shaped article, for example, the filter. Such an object may be, for example, a capsule or a carbon piece.

Figure 1 shows an embodiment of a device according to the invention for use in the production of smoking articles.
Figure 2 shows the areas of the tipping paper in various processing steps.
Figure 3 shows the various process steps for producing a filter cigarette.

As used herein, the terms "matched" or "to match" generally define the alignment of two or more objects, e.g., cutout areas and barred articles or pre-applied patterns (see below). In this regard, the term "alignment " includes not only an arrangement of objects in a relatively well defined positional relationship with respect to each other, but also an arrangement of well defined overlapping / . The matching process may be implemented, for example, as part of a control loop for controlling the device, or alternatively or additionally, at the start-up of the device.

Waste sheet material, for example, waste sheet material that occurs during the manufacture of smoking articles, may seriously interfere with the manufacturing process unless properly handled. Generally, the waste sheet material is not produced in processes involving only printing, embossing or perforation of the sheet material. Typically, the perforated material in the perforation process does not produce a waste sheet material separate from the sheet material, but is generally grabbed downward and laterally from the plane of the sheet material.

In the device according to the invention, however, there is this cutout piece, and the cutout piece due to the cutting process is removed from the removal unit. The removal unit is preferably disposed close to the position where the cutout piece is produced, for example, inside the cutting unit itself.

It is possible to add features or enhance features to a bar-like article, for example a smoking article, using a sheet material comprising a cut-out area. Such features may be used for aesthetic reasons, but may also be used to influence the sensory attributes of the smoking article. The sensory attributes are, for example, attributes relating to the visual sense, palate, tactile sense or smell of a rod-shaped article.

As used herein, the term "cutout area " refers to a portion of a sheet material in which a pattern, logo, or any other shape is formed, corresponding to a cutout piece that is cut from the sheet material. The cutout region may include only one hole, an array of holes, or multiple holes of various shapes, sizes and arrangements. Hereinafter, for the sake of simplicity, the term "pattern" is used, meaning that it encompasses all the different arrangements or structures of the aforementioned cutout regions.

Thus, the cutout piece may be one piece of sheet material, or it may be various pieces depending on the pattern cut from the sheet material in the cutting unit. Thus, the singular term "cutout piece" is used to describe one or more portions of the sheet materials that are cut from the sheet material in the cutting unit.

Preferably, the sheet material is a cellulosic material such as, for example, paper. Alternatively, the sheet material may be made of a foil metal foil made of a plastic material, or a layered structure such as a laminate comprising two or more layers selected from, for example, paper, paperboard, plastic or metal.

In one embodiment of the apparatus according to the invention, the lapping unit comprises at least a first rod-shaped element and a second rod-shaped element, wherein the wrapping unit is formed by wrapping a sheet material comprising a cut-out region at least partially around both the first and second rod- And to assemble the bar-shaped article through engagement. By suitably wrapping the sheet material around the first and second bar-shaped elements, including the cut-out area, the cut-out area may be completely disposed in the first bar-shaped element or disposed in the second bar-shaped element, or The cutout region may be disposed on both the first and second bar type elements.

In the manufacture of a filter cigarette, the filter cigarette is made by forming a filter cigarette through binding the filter rod to the cigarette bar by wrapping the tipping paper around both the cigarette and filter rods. Thus, in the production of the filter rod, the tipping paper may be a sheet material including the cut-out area. The wrapping unit may be further configured to assemble a pair of smoking articles as described below.

In another embodiment of the device according to the invention, the sensing part is arranged to sense a pre-applied pattern on the sheet material so that the pre-applied pattern and the cut-out area are matched. The sensing part for sensing the pattern previously applied on the sheet material need not be the same as the sensing part for determining the cutting position. However, thereafter, the sensing unit for determining the pre-applied pattern also works in connection with the positioning unit.

The cut-out areas may be combined with pre-applied patterns that already exist on or within the sheet material and match them so that additional sensory effects may be created or influenced. For example, a cutout area in the form of a logo may be made visible by superimposing a cutout logo with a printed pattern in the form of the same logo or the same logo. The pattern previously applied to the sheet material may include, for example, a print pattern, an embossing pattern, a perforation pattern, or a combination thereof. However, the pre-applied pattern may also include additional patterns suitable for providing, for example, a sensory response. The term "pattern" is used again in the broad sense already defined above with respect to the cutout region.

The pre-applied pattern already exists in or on the sheet material at the time the sheet material is fed into the apparatus (e.g., it may have been applied to the sheet material before placing the bobbin with the reel of sheet material in the apparatus). Alternatively, a previously applied pattern may be produced in the apparatus itself in one or more sheet material processing steps before the sheet material is transferred to the cutting unit. The sensing unit senses the position of the pre-applied pattern. The sensed position of the pre-applied pattern is then used by the positioning unit to position the sheet material in the cutting unit in such a way that the cut-out area is matched to the pre-applied pattern.

In another embodiment of the device according to the invention, the cutting unit is configured to cut the cutout piece from the multilayer sheet material as the sheet material. Advantageously, said cutout piece is incised in such a way that at least one layer of said multi-layer sheet material remains uncut. The use of a multi-layer sheet material with at least one notched layer is advantageous in that the bar-shaped article includes features of the cut-out region, but other performance can be made unchanged. Leaving at least one layer of uncut portion may advantageously not require a change in other design parameters of the smoking article. Advantageously, the non-cut layer can provide the suction resistance of the same smoking article as a simple monolayer sheet material used in conventional smoking articles, such as, for example, tipping paper. In addition, the remainder of the sheet material prevents unintentional loss of material, for example tobacco, through the cutout portion.

Cutting the multi-layer sheet material without cutting at least one layer can be accomplished, for example, by providing a stopper in the cutting operation, or by placing a space between the die cutters for the at least one layer in a suitably spaced apart position By the placement of corresponding die cutters, or by any other suitable means known in the art.

In another embodiment of the device according to the invention, the wrapping unit is configured to couple the notched layer to one side of the sheet material comprising the cutout area. Bonding the non-cut layer to the sheet material comprising the cut-out area is such that the non-cut layer covering at least the cut-out area of the sheet material prior to bonding the sheet material to the non- As shown in Fig. This embodiment has the same advantages as the embodiment using the multi-layer sheet material, especially because the uncut layer is bonded to the sheet material including the cut-out area to cover at least the cut-out area. Further, in bonding the notched layer to the sheet material including the cutout area, a standard cutting unit configured for cutting the conventional single-layer sheet material may be used. This may simplify the removal of the cutout piece. For example, bonding the non-cut layer to the sheet material comprising the cut-out area may be performed by pasting. Preferably, the notched layer is a conventional sheet material used in the production of the bar-shaped article, and is preferably provided with the same or smaller dimension than the sheet material having the cut-out region. For example, the uncut layer may be in the form of a band of sheet material.

Layers made of a material that is a single-layer material that is not suitable for wrapping rod-shaped articles such as smoking articles, when using sheet materials comprising multiple layers having cut-out areas before or after each layer is bonded, Layer. ≪ / RTI > This non-conforming material may be, for example, a material that is too thin or too porous to be used as a single layer sheet material.

In another embodiment of the device according to the invention, the removal unit comprises a vacuum unit or an air injection nozzle for removing cutout pieces from the cutting unit. The vacuum unit creates a negative pressure to suck up any cutout pieces or dust produced during cutting of the sheet material. If an air injection nozzle, for example pressurized air, is used, the cutout piece is blown away by air injection. Both methods for removing cutout pieces have the advantage that they are very effective in removing lightweight materials. Both alternatives have no mechanical contact to the sheet material and can be placed at a distance from the cutting position. The cutout pieces removed by the vacuum unit or the air injection nozzle may be collected in a waste basket or recycling bin, or may be transferred to such a collection device.

According to another embodiment of the device according to the invention, the removal unit comprises a sensing unit for sensing cutout pieces cut from the sheet material. The sensing unit provides an information signal indicating the presence or absence of a cutout piece. The sensing unit senses whether the cutout piece is actually cut from the sheet material and whether it is properly removed. The sensing unit may be configured to send an alert signal if no cutout piece is generated or if the cutout piece is not properly removed. The sensing unit is particularly suitable for indicating a malfunction of the device at an early stage before the bar-shaped article is assembled. The sensing unit may be, for example, a light sensing unit.

In another embodiment of the device according to the invention, the wrapping unit is configured to assemble a pair of bar-shaped articles. Each of the bar-shaped articles includes a cigarette bar and a filter rod. The assembly includes placing cigarette rods such that one end of the pair of cigarette rods faces the other end of the pair of cigarette rods and a double-length filter rod is disposed between the two opposite ends of the cigarette rods . The double-length filter rod is then coupled to the two cigarette rods by at least partially wrapping the sheet material including cutout areas around each cigarette and double-length filter rods. The apparatus further comprises a cutter for cutting the double wrap filter rod thus wrapped. Two filter cigarettes are allowed to be made at one time by using double-length filter rods cut into the middle after being bonded to two cigarette rods.

According to another aspect of the present invention, there is provided a method of manufacturing a bar-shaped article. The method includes the steps of providing a sheet material and cutting the cutout piece from the sheet material to produce a sheet material comprising a cutout area. The method includes removing the cutout piece, placing the sheet material with the cutout area to match the bar-shaped article, as well as arranging the sheet material including the cut-out area at least around the bar- Further comprising the step of wrapping.

In one embodiment of the method according to the present invention, the step of providing sheet material comprises providing a multi-layer sheet material. In addition, cutting the cutout piece includes cutting the sheet material in such a manner that at least one layer of the multiple layers remains uncut.

Yet another embodiment of the method according to the invention is characterized in that it further comprises the step of bonding said individual notched layer to a sheet material comprising said cutout area in such a way that a separate uncut layer covers at least the cutout area of the sheet material .

The advantages of the implementations of the method according to the present invention have been discussed above with respect to embodiments of the devices already in place so that they will not be discussed again.

In a variant of said last two embodiments of the method according to the invention, said at least one uncut layer or individual notched layer is made of a material selected from the following group:

- transparent materials,

In the case of using a multi-layer sheet material, a material comprising a functional characteristic different from that of one or more different layers, or a material comprising a functional characteristic different from that of a sheet material when using a separate uncut layer,

- a material with a permeability of less than 600 korean units.

The use of a transparent or translucent layer allows the bar-shaped article to be seen through, for example, on the cigarette top of a cigarette rod or on the filter material of the filter rod. For example, due to the different colors of the cigarette and wrapping sheet material, the cutout area may be visually emphasized and the shape of the cutout area may be emphasized. In general, in the case of one or several additional layers as well as the not-cut layer, different (uncut) layer (s) or materials different from the sheet material, especially those with different sensory properties are used. The sensory attributes of visual, taste, tactile or olfactory may be used individually or in combination. The use of layers with additional properties as well as other sensory attributes, such as taste or odor, is applied to the bar-shaped articles. It is also possible to enhance certain characteristics such as the shape of the logo, for example, by providing a lower layer of a different color from the layer (s) comprising the cut-out region. Since the non-cut layer is generally the innermost layer when viewed from a bar-shaped article, a material having a low transmittance or even a hermetic material is preferably used in the case of the non-cut layer. The transmittance is preferably selected so as not to change the suction resistance of the smoking article.

In another embodiment of the method according to the invention, the sheet material has a previously applied pattern on the sheet material. Wherein the step of disposing the sheet material at the cutting position further comprises disposing a cutout piece to be cut to match the previously applied pattern. In a further step, the cutout piece is cut out of the sheet material to produce a sheet material comprising a cutout area that is mated with a previously applied pattern. The advantages of this embodiment of the method according to the invention have already been discussed above in relation to the present apparatus so that they will not be discussed again.

In another embodiment of the method according to the invention, the sheet material is a tipping paper, a tobacco wrapping paper or a filter plug wrapping paper. The apparatus and method according to the present invention advantageously provide an individual smoking article having an aesthetic or sensory effect compared to the effects of a sheet material comprising cutout areas, such as articles wrapped with a sheet material without a cutout area, Is applied to a sheet material used for manufacturing a smoking article such as a cigarette.

The present invention is directed to, and is suitable for, smoking articles that include primarily filters, but may also be applied to, for example, filterless smoking articles or cigarettes.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to embodiments shown by the following figures.

1 Shows an embodiment of a device according to the invention for use in the production of smoking articles;

2 Shows the areas of the tipping paper in various processing steps;

3 Show various process steps for producing a filter cigarette;

Fig. 1 shows an apparatus 1 for use in the manufacture of rod-shaped articles, for example smoking articles, such as filter cigarettes. The apparatus 1 comprises a holder 2 such as a bobbin holding a reel 3 of a sheet material 20 such as a tipping paper. Arrange the conveyor roller (4) to convey the web of tipping paper unwound from the reel (3) through the device (1). The individual tipping paper portions 22, 23, 24 are cut from the web of the tipping paper and each of the portions 22, 23, 24 is used to form a pair of filter cigarettes. The wrapping unit 14 attaches the double-length filter rod 17 to the pair of tobacco rods 15, 16 using the tipping paper portions 22, 23, 24. Then, the double-length filter rod 17 is cut with a suitable cutter (not shown) such as a knife or a blade to form a filter cigarette pair.

The apparatus 1 comprises a tension arm 6 arranged to adjustably secure the tipping paper tension at the required level. The apparatus 1 further includes registration rollers 7 capable of withdrawing tipping paper from the holder 2 and which can be driven by a motor (not shown) such as, for example, a servo motor.

The registration rollers 7 may delay or advance the tipping paper or may be driven by a motor (not shown). The webs of the tipping paper web may therefore be withdrawn from the reel 3, since the registration rollers serve as positioning units to position the tipping paper at any desired position of the subsequent cutting unit and may additionally serve as a drive roller .

The apparatus 1 further comprises a cutting unit comprising a pair of cutting rollers 8 arranged to cut the cutout piece from the tipping paper to produce a sheet material 21, The web of paper includes a cut-out area 210 (see FIG. 2). For this purpose, one or both of the cutting rollers 8 are provided with a cutout area 210 (or any other cutout) on the web of the tipping paper as the web of tipping paper is passed between the cutting rollers 8 A cutting blade or a cutting edge capable of forming a pattern) may be provided. The cutting rollers 8 may be replaced by any other suitable cutting means, such as, for example, a laser knife.

The cutting roller speed may be determined by the apparatus speed, the matching roller speed, or the driving roller speed. The cutting rollers 8 can be installed, for example, in a conventional tipping paper traction roller seat of a conventional cigarette making machine.

One of the cutting rollers 8 preferably has a peripheral region that is not cut. The non-cut areas are arranged so that the cutting rollers do not touch the tipping paper during rotation. Thus, when the rotational position of the cutting roller is within a predetermined range, the cutting roller does not make contact with the tipping paper. Thus, the registration rollers 7 can adjust the position of the tipping paper without the paper contacting the cutting roller. So that the position of the tipping paper can be adjusted independently of the rotation of the cutting roller. Thus, the registration rollers can advance or retard the print pattern when the cutting rollers are not cutting, for example, by a predetermined or predefined pattern, such as the print pattern 110, Can be positioned relative to the cutout area 210 to be cut. The matching rollers may also position the tipping paper such that the cutout area 210 to be cut out has a cutout area (with or without previously applied pattern) to match or match the bar type article to be wrapped with the provided tipping paper. Although it has been described above that the area without the incision is disposed on one of the cutting rollers, each of the cutting rollers 8 may have a portion without incision. On the side of the cutting unit, a removal unit (5) is arranged to remove cutout pieces from the cutting unit. It is important to remove the cutout pieces to a reliable level because the residual cutout pieces may seriously hinder the manufacturing process or may inadvertently affect the quality of the product. Thus, the removal unit 5 may comprise a waste drum, for example comprising a suction device which sucks into the waste drum with the aid of a negative pressure to remove the cut-out pieces. As an alternative to this negative pressure, or in combination with it, the elimination unit 5 can generate an air jet as a constant or individual jet stream to remove the cut-out pieces, for example, by blowing them into the waste drum or into the recycling bin An air injection nozzle for supplying air to the nozzle.

The negative pressure and air injection may also be combined to enhance the efficiency of the removal unit 5. With the aid of a sensing unit (not shown), it may be sensed whether the cutout piece is indeed cut out of the sheet material or whether the cutout piece has been properly removed by the waste removal unit. An alarm signal may be generated during a malfunction.

A control (not shown) or any other suitable means may determine the cutting position for the tipping paper. This cutting position may depend on the detected area or position of the print or other pattern on the tipping paper. Once the cutting position is determined, the tipping paper is positioned with the aid of the positioning unit. This is preferably done so that the previously applied pattern on the tipping paper when in the cutting position and the cutout area to be cut off from the tipping paper are matched. However, it may also be performed to match the bar-shaped article when the cut-out area to be cut off from the tipping paper is tapped to the tipping paper. To this end, the control unit may control a motor for driving the registration rollers 7. [

The tipping paper may be printed in advance with the print pattern 110, embossed in an emboss pattern, or otherwise provided in a previously applied pattern (see FIG. 2). For simplicity in the following, the following printed pattern 110 represents all other types of pre-applied patterns or combinations of pre-applied patterns. The printed pattern 110 on the tipping paper may include, for example, a plurality of logos associated with a particular cigarette brand. The device 1 further comprises a light sensing portion 9 such as a charge coupled device (CCD) camera for sensing the location or position of the print pattern 110 on the tipping paper, for example representing the sheet material 20 . If no print pattern should be detected, the light sensing unit 9 may be omitted.

As will be described in more detail below, the individual portions 22, 23, 24 of the tipping paper with cut-out regions 210 each include a pair of logos for use in a pair of filter cigarette assemblies You may.

FIG. 2 shows the portions of the tipping paper at various locations 100, 200 and 300 of the apparatus shown in FIG. In position 100 (sheet material 20 is not yet cut), the bottom of the tipping paper 20 is aligned with the printing pattern 110 comprising a plurality of identical "V" Respectively. The upper portion of the tipping paper has a print pattern 110 that includes the lower "V" logo, but the upper "V" logos are turned upside down so that they form a mirror image of the pattern printed on the underside .

At position 200, for the two logos in the right and leftmost "V" logos, the tipping paper 21 has already been partially broken, but still contains the printed "V" In addition, the cutting target cutout piece is indicated by the dotted line 211 around the "V" logo displayed at the leftmost position. As shown, the dashed line 211 is in alignment with the "V" logo 110 printed on the tipping paper. After the cutout piece 212 is cut out at each position of the tipping paper, the tipping paper includes a cutout area 210 corresponding in shape to the cutout piece 212. In the embodiment of the cutting process described above, the pre-applied print pattern 110 is also completely cut so that the print pattern 110 only acts as an indication of the position only when the cutout piece is to be cut. However, it is also possible to produce a cutout piece that leaves some tipping paper between the cutout piece and the printed pattern 110. Many additional configurations of cutout pieces as previously described above may be contemplated.

1, the apparatus 1 may be applied to a tipping paper to form a double-length filter rod assembled into a cigarette in the wrapping unit 14, and a tipping paper for attachment to cigarette rods, And a gummer roller (10) for producing a gummer roller (10).

The apparatus 1 also includes a cutter 11 for cutting the tipping paper into sections 22, 23, 24 for use in attaching filter rods to individual tobacco rods. The cutter 11 may include a knife drum 12 and a vacuum drum 13. In operation, the vacuum drum rotates faster than the knife drum, ensuring that the cut tipping paper is blown off before cutting the next part. The gear mechanism connected to the knife drum and the vacuum drum may be used to achieve the required rotational speed difference. The cutting speed may be determined from the apparatus speed, the matching roller speed, or the driving roller speed. Thus, the cutting speed and the cutting roller speed may be dependent on each other. For example, encoder information may be sent to the control to adjust the feed rate to ensure accurate offset with the cutter. The control unit may be configured to control the cutter 11 such that each cutting region 22, 23, 24 of the tipping paper has one cutout sub pattern. FIG. 2 shows portions 22, 23 and 24 of the tipping paper at the 300 position where the lower cut-out regions are oriented regularly while the upper cut-out regions are oriented upside down.

The logo and cutout region 210, as described above in FIG. 2, may be realized in a variety of ways. For example, dotted lines 211 may be provided to reinforce the " V "shape of the print pattern 110 by forming a larger" V "outline around the printed" V "logo of the print pattern 110, Each of a plurality of small cut portions can be formed on the tipping paper. Alternatively, as shown in Fig. 2, a larger "V" with printed pattern 110 is fully cut. In the latter case, the cutout sheet material may be a multilayer sheet material, at least the upper layer being cut in the cutting process. The printed "V" symbol remains visible at least on one or more underlying layers where the bottom layer is not cut.

If the underlying layer is made of a transparent material or has a color that is different from the color of the layers or layers having large cut-out areas, a larger area of incision is particularly effective instead of making only small individual cuts around the printed pattern 110 . Using a transparent material, the lower filter material or tobacco material may be visualized in the form of a special shape, logo or pattern. By using different colors of cut and uncut layers of multi-layered tipping paper, visibility of the logo can be significantly improved compared to layers having all the same color. Similar or different effects may also be achieved by using layers of different sensory attributes such as different visual, tactile or other characteristics.

As an alternative to the above cut of the multi-layer sheet material, a single layer sheet material can be used. In this alternative, before the cutout sheet material is conveyed to the wrapping unit 14, the second uncut layer is attached to the sheet material 21 including the cutout area 210. The second uncut layer is attached in such a manner as to cover at least the cutout region 210. As such, the tipping paper containing the cut-out region 210 and the applied uncracked layer forms at least two laminated sheet materials in the cut-out region 210. The second uncut layer preferably has a different color than the single layer sheet material or is made of a transparent material, as already described above in connection with other embodiments.

Implementation An example of the manufacturing steps performed in the wrapping unit 14 of the apparatus 1 will be described with the help of Fig. The wrapping unit is arranged between the drive rollers (not shown) axially in the manner shown in Figure 3 (top position), between the first paper wrapping cigarette rod 15, the second paper wrapping cigarette rod 16, The double-length filter rods 17 are continuously aligned. A portion 24 of the tipping paper, for example a paste 24 already shown in FIG. 2, is then wrapped around the double-length filter rod 17 and partially around the first and second cigarette rods 15, Wrapped around. In this way, the double-length filter rod 17 is engaged in both the tobacco rods 15, 16 (the center position in Fig. 3). The wrapped double-length filter rod 17 is then cut in the middle, thereby forming a pair of assembled filter cigarettes 18 (the lowest position in FIG. 3). The assembled filter cigarette 18 is wrapped around a wrapped filter rod 19, a wrapped cigarette rod 15, and a partially extended and wrapped filter rod 19 around the cigarette rod 15 of the filter cigarette And includes a generally cylindrical wrapped portion of fully extended tipping paper 25. This applies analogously to a filter cigarette comprising a second tobacco rod 16. The wrapped portion of the tipping paper 25 includes a cutout region 210 having an enlarged "V" shape. A wrapping unit 14 capable of cutting a pair of attached filter cigarettes is known as such.

The described apparatus 1 is characterized in that the cutting process of the logo is performed while the tipping paper is unwound from the bobbin 2 so that the tipping paper is distorted or crushed by the tension of the paper as in the case of paper which is cut before being wound on the bobbin .

In the following, this method during use is further described. In the first step, a bobbin of the tipping paper 20 (pre-printed material) including the printing pattern 110 is mounted on the holder 1. In the next step, the tension arm 6 adjusts the paper tension to the required level on the tipping paper. In the next step, the light sensing portion 9, for example a CCD camera, senses the position of the print pattern 110 (printing) on the tipping paper. Then, the position information on the position of the print pattern 110 is transmitted to the servo control motor of the registration roller 7. [ Then, in response to the positional information, the registration roller 7 positions the respective printing patterns 110 on the tipping paper at the necessary cutting positions with respect to the cutting rollers 8 by raising or lowering the speed, 110) and the cutout area to be produced can be matched. In the next step, the tipping paper is cut to provide the cutout area 210 to match the printed pattern 110. The glue roller 10 then applies a paste to the tipping paper 21 comprising the cutout area 210. The cutter 11 then cuts the tipping paper into individual portions 22, 23, 24. Finally, the cut portions 22, 23, 24 of the tipping paper comprising the cutout region 210 are wrapped around aligned double-length filter rods and tobacco rods 15, 16.

If there is no print pattern 110 on the tipping paper to be matched with the cut-out area 210, the step of sensing the print pattern 110 may be omitted. In this case, the light sensing portion 9 for sensing the print pattern 110 may be omitted in this case. In the registration step, the cutting position is then set relative to the tipping paper.

In another embodiment of the device 1, the embossing unit may be arranged before or after the cutting unit 8. Therefore, it is possible to combine the cutout area 210 and the printed pattern 110 or the embossed pattern in the sheet material 20 for use in manufacturing a cigarette, thereby improving various special appearance of the smoking article. The embossing unit is preferably combined with a registration roller 7 or a separate registration means to align the embossing pattern with the cutout area 210 and possibly the print pattern 110 as well.
