This object is achieved by a method for producing a strand of the tobacco processing industry, comprising a method for processing a wrapping material strip for a rod-shaped article of the tobacco processing industry with the following method steps:

• Providing the wrapping material strip,
• Conveying the wrapping material strip in a longitudinal axial conveying direction to an embossing device and
• Embossing the wrapping material strip, wherein the wrapping material strip is conveyed at least temporarily during embossing,
• Conveying the embossed wrapping material strip to a formatting device, wherein in one run-in region of the formatting device a strand material is dispensed onto the embossed wrapping material strip and the embossed wrapping material strip is also laid on another wrapping material strip; and the embossed wrapping material strip and the further wrapping material strip are conveyed around the strand material during longitudinal conveyance through the formatting device to be wrapped around that is further developed in that the embossed wrapping material strip between the embossing device and the inlet region of the formatting device is guided in at least two places in succession in the conveying direction of the embossed wrapping material strip by a respective guide, wherein the embossed wrapping material strip at least in the guide, which is adjacent to the inlet region of the Formalvorrichtung or adjacent to the lead-in area of the format device is guided laterally at both edges of the embossed wrapping material strip.

By means of the method according to the invention, it is possible to apply the embossed wrapping material strip very precisely onto the further wrapping material strip, so that a very exact strand production is possible. In this case, a complex position control of the wrapping material strips to each other may even be avoided or at least simplified.

Characterized in that the embossed wrapping material strip at least in the guide, which is adjacent to the lead-in area of the format device or adjacent to the lead-in area of the format device is guided laterally at both edges of the embossed wrapping material strip, a particularly precise guidance is possible without providing a degradation of the embossing ,

Further preferably, the embossed wrapping material strip at least in the guide, which is adjacent to the inlet region of the format device or adjacent to the inlet region of the format device, guided from below and / or above. By guiding from below, it is also possible to combine the wrapping material strips very precisely, since sagging of the embossed wrapping material strip is avoided and thus It is also avoided to cause waves in the longitudinal axial conveying direction of the wrapping material strip, in particular of the embossed wrapping material strip. By guiding from above any vibrations of the wrapping material strip are prevented during transport.

In this case, the guide, which is provided from below, is preferably aligned with the wrapping material strip in alignment between the embossing device or another guide or the further point at which the embossed wrapping material strip is guided, and the format device. The guide which guides the embossed wrapping material strip from below can also be arranged somewhat below the alignment between the embossing device or the further guide and the format device. This avoids that the embossed wrapping material strip is degraded with respect to the embossing, which could happen, for example, when the wrapping material strip would be deflected around a guide with a certain pulling force.

Preferably, the further wrapping material strip is glued to the side of the further wrapping material strip facing the embossed wrapping material strip prior to contact with the embossed wrapping material strip, in particular over the whole area. As a result, a very firm contact of the two wrapping material strips is achieved. In particular, then the wrapping material strips can no longer slip to each other, resulting in a very high quality strand.

The further wrapping material strip can be the otherwise usual wrapping material strip which is wound around strand material in a formatting device and is closed in order to bring the strand material in the form and to keep in shape.

The strand material can be tobacco or filter material, for example filter tow. Furthermore, the strand material may be composed of filter segments. To produce such a strand, for example, on the EP 1 427 299 B1 referenced, in which by means of several independent functional units, which are designed as modules and which together form a Filtersegmentzusammenstellmaschine or a part of the Filterherstellmaschine, filter segments are assembled, which are promoted in the compilation queraxial and then transferred with a transfer device in a longitudinal axial conveying movement be transferred to a strand of a stranding machine. In the stranding machine, the strand is then guided in the longitudinal axial conveying direction and enveloped by the wrapping material (s), in order subsequently to cut off corresponding filter rods.

With regard to the processing of FilterTow is on the EP 1 625 799 B1 See, from a filter manufacturing machine of the tobacco processing industry is known, in which a filter rod machine and a filter tow preparation machine are connected to each other to provide the filter manufacturing machine. Here, filter tow is withdrawn from a filter towball, processed in the filter preparation machine, for example, stretched and sprayed with triacetin, to be subsequently transferred to the filter rod machine and there to form a filter strand, which is for example coated with a wrapping material. Finally, corresponding filter rods are cut to length from the filter strand.

The object is further achieved by a device for producing a strand of the tobacco processing industry comprising a stranding machine, wherein an embossing device is provided with two embossing rolls, by means of which the wrapping material strip is embossed or embossed during a longitudinal axial promotion of the wrapping material strip, which is further developed by in that at least two guides are provided downstream of the embossing device, which are arranged one behind the other in the conveying direction of the embossed wrapping material strip, the stranding machine having a conveying device with a further guide for a further wrapping material strip.

By the device according to the invention a very precise production of a strand of the tobacco-processing industry, in particular a filter strand from which subsequently filter rods can be cut, possible.

The conveying device of the stranding machine according to the invention can promote the further wrapping material strips, wherein as a further guide a deflection roller can be provided for the further wrapping material strip. According to the invention, one of the at least two guides is adjacent to an inlet region of the format device or adjoins the inlet region of the format device. As a result, a very precise placement of the embossed wrapping material strip on the other wrapping material strip is possible, even without position control or with a simplified position control a very precise juxtaposition is possible.

According to the invention, at least one guide, in particular preferably the guide, which is adjacent to the inlet region of the format device or to the inlet region of the format device adjoins, lateral cheeks. By the lateral cheeks whose distance is preferably adjustable and / or predetermined, a very accurate position limitation of the wrapping material strip is possible. Due to the preferably provided adjustability of the distance between the lateral cheeks, different widths of wrapping material strips can be used, so that when the format is changed, rapid adjustability of the guide or the lateral cheeks of the guide is possible. Preferably, the at least two guides each have lateral cheeks.

According to the invention, at least one guide, in particular preferably the guide which is adjacent to an inlet region of the format device or adjoins the inlet region of the format device, has a surface which limits a movement of the embossed encapsulation material strip downwards and / or upwards. As a result, a very precise guidance of the embossed wrapping material strip is made possible also in the longitudinal axial direction, and thus a very precise placement of the embossed wrapping material strip onto the further wrapping material strip. Preferably, the at least two guides each have a surface which limits movement of the embossed wrapping material strip downwards and / or upwards.

Preferably, the surface is curved, in particular preferably circular or elliptical. This efficiently reduces the degradation of the embossed wrapping material strip.

Particularly preferred is a variant in which the inventive device as a slide-in device or process unit of a Insertion device is formed, wherein the insertion device between a filter rod machine and a filter tow preparation machine or a filter segment assembly machine for multi-segment filter is mounted or mountable, wherein the insertion device comprises in particular a supply unit which is releasably connectable to the process unit.

With regard to this preferred embodiment of the device according to the invention, reference is made in particular to the Applicant's patent application with the file reference DE 10 2011 085 981 A1 and the title "Filter Making Machine of the Tobacco Processing Industry".

As a result of this preferred measure, the filter production is more flexible than hitherto possible, since the filter material and / or the wrapping material strip can be processed or processed very variably by the insertion device. By providing one or more slide-in devices, different processing or conditioning processes can also be provided, whereby a different type of processing or processing is made possible by exchanging the respective process unit with another process unit. Thus, it is also possible to change very quickly from the production of one type of filter to another type of filter, as a result of which the filter change can be designed very efficiently. For example, this measure can very quickly provide a different type of embossing on the wrapping material strip. According to the invention, for example, a longitudinal axial embossing is provided. However, other types of embossing could be provided, which are then possible on the corresponding insertion device or the process unit of a slide-in device. Furthermore, another wrapping material can be processed accordingly or the wrapping material can be easily processed or processed with another liquid even at other process temperatures. For this purpose, for example, only the process unit must be replaced, which is then connected to the supply unit.

Preferably, one of the at least two guides is fixed to a wall of the insertion device adjacent to the filter rod machine, wherein the one of the at least two guides is arranged towards the stranding machine. This makes it possible, at least easy to exchange the process unit, and so, that few adaptation measures have to be made. In addition, in this way one of the at least two guides can be attached very close to the format device of the strand machine, in particular the filter rod machine.

Preferably, as an alternative or in addition, one of the at least two guides is mounted on the stranding machine, in particular an inlet funnel of the stranding machine. The feed hopper serves, for example, to bundle filter tow as a strand material and compress it in order to deposit it on the embossed wrapping material strip. According to the invention, a filter manufacturing machine of the tobacco processing industry comprises an aforementioned device according to the invention with the corresponding aforementioned features.

Fig. 1 schematically shows a plan view of a filter manufacturing machine according to the invention with a device according to the invention for processing a wrapping material strip. The filter-making machine comprises a filter tow-making machine 20 and a filter-rod machine 40, as described, for example, in US Pat EP 1 625 799 B1 are described. According to the invention, an insertion device 30 is now provided by means of which the wrapping material strip 33 can be processed according to the invention. In Fig. 1 the components for processing the wrapping material strip 33 are indicated only schematically and will be described in more detail below.

In Fig. 1 are in the conveying direction 100, a filter fabric preparation machine 20, the insertion device 30 and then the filter rod machine 40 arranged one behind the other. The arrangement is in this embodiment consecutively aligned or behind one another in a line. In the filter wire preparation machine 20, filter tow 11, which is drawn off from a filter towbale 10, is prepared, for example, stretched, pulled apart and sprayed with triacetin to be subsequently transferred through an inlet funnel 41 of the filter rod machine 40, which then a formatting device 42 connects. Processing steps, for example on the wrapping material strip 33, can now be carried out by the insertion device 30. In addition, processing steps can also be carried out on the filter tow. However, these further processing steps on the filter tow are not explained in detail.

In the embodiment according to the Fig. 1 Now, for example, a wrapping material strip 33 is embossed by the first embossing roll 34, which is in engagement with the second embossing roll 35. The processed or embossed wrapping material strip 33 then passes in the figure according to Fig. 1 below the filter towers 11 and below the inlet funnel 41 into the format device 42. In the format device 42, the filter tow strip 11 is deposited on the wrapping material strip 33. In the formatting device 42, the wrapping material strip is then wound around the filter tow strip 11 and, accordingly, a longitudinal seam is closed by gluing. Alternatively, the wrapping material strip 33 may be wrapped around the filter tow 11, and another wrapping material strip, not shown, wrapped around the processed wrapping material strip 33 and correspondingly provided with adhesive, may be wrapped around the filter tow 11. As a result, can be made by cutting the resulting filter strand corresponding CP filter.

In this exemplary embodiment, the insertion device 30 looks like it is divided into a supply unit 31 and a process unit 32. The supply unit 31 serves to supply electrical energy, for example current and voltage, compressed air, if necessary, water cooling or a heating with a heated one Water and a controller. In the process unit could Also, a control device may be provided, and otherwise the device features that are necessary or desirable in this case for the embossing.

As an example, which features may be desired in a corresponding process unit will be discussed below Fig. 2 received. However, it should first be pointed out that the insertion device 30 can be detachably connected to the filter strand machine 40 at its respective first side 91 and can be detachably connected to the filter fabric preparation machine 20 on its second side 92. In addition, it is possible that a plurality of insertion devices 30 are arranged one behind the other in the conveying direction 100 in order to provide further functionalities for processing wrapping material strips 33 and / or the filter tow. Preferably, only the supply unit 31 can be directly connected to the filter tow preparation machine 20 and the filter rod machine 40. The process unit 32 is then exclusively connectable directly to the supply unit 31. In addition, other processing units 32 could be used with which different types of embossing can be ensured, in such a way that a quick and easy change to the different processing units 32 is possible.

Fig. 2 schematically shows a filter manufacturing machine according to the invention of the tobacco processing industry with a very schematically illustrated Filtertowaufbereitungsmaschine 20, a device according to the invention for processing a wrapping material strip, for example in the form of the insertion device 30 and a filter rod machine 40, which is also shown very schematically. The processed filter tow 11 from the filter fabric preparation machine 20 is fed via rollers 61 above the web of the wrapping material strip 33 of the wrapping material strip processing apparatus according to the invention steered and then threaded or introduced into an inlet funnel 41 of the filter rod machine.

A wrapping material strip 33 is fed from outside the insertion device or alternatively from a supply in the insertion device 30, which is not shown and may for example be a bobbin or a bobbin changer, to a wrapping material strip tensioning device 55 via rollers 60, which ensures that the wrapping material strip as constant as possible predetermined tensile force is encouraged, steered. This is followed downstream of the wrapping material strip tensioning device 55 by a moistening device 50 in which the wrapping material strip 33 is moistened, for example with water, which is preferably mixed with a stabilizing agent, for example methyl cellulose. Upstream and / or downstream of the humidifier 50, a heater may be provided to heat the wrap strip of material. The heater can exploit heat radiation, for example, or hot air can be used here. When using methylcellulose as an additive, for example to water, the subsequent embossing is more stable. The moistening is preferably done so that the wrapping material strip 33 has a moisture content of 5 to 13 percent by mass, especially preferably 7 to 9 percent by mass and in particular 8 percent by mass, during embossing. Humidification happens in Fig. 2 one-sided from below. Particularly preferred is an embodiment in which the humidification from both sides, ie in addition to the embodiment of Fig. 2 , also happens from above.

The moistened wrapping material strip is then conveyed in the conveying direction 90 via deflecting rollers 60 to an embossing device 36. The embossing device 36 comprises a first embossing roller 34 and an embossing roller 35, which will be explained in more detail below. As a result, preferably a longitudinal axial embossing of the wrapping material strip is achieved, ie an embossing, which shows a waveform in a section transverse to the longitudinal axis of the wrapping material strip.

The humidifying device 50 may also be omitted. However, the provision of the moistening device 50 is preferred.

In Fig. 2 In the embossing device 36, a heating device 56 is integrated, which heats the wrapping material strip, in particular further, by means of heat radiation, for example infrared radiation. It can also be a heater in one or both embossing rollers 34, 35 may be provided.

At least one embossing roll, in Fig. 2 the first embossing roll 34 is provided with a pivoting device 64 which, in the case of a winder, enables the swaging of an embossing roll from the other embossing roll. Preferably, two pivoting devices, ie for each embossing roller a pivoting device 64, are provided. The embossing rollers 34 and 35 may also be arranged linearly displaceable. Downstream of the embossing device 36 may be provided a spraying device in which the embossed wrapping material strip is sprayed with a fluid. For example, by spraying with water, in which a stabilizing agent, in particular methyl cellulose, is introduced, provide for a very stable embossing. Alternatively or additionally, paint may also be applied to embossed wrapping material strip 33 and / or flavor carriers such as a menthol flavor or other additives. Besides, it is possible to glue here to apply, for example, an internal glue trace in the filter production and / or glue for connecting the embossed wrapping material strip with another wrapping material strip. The inner glue track serves, for example, for bonding the wrapping material strip 33 with a filter rod material 11.

Further details of the apparatus and a preferred method of embossing a wrapping material strip are for example EP 2 620 062 A2 and DE 10 2012 215 589 A1 refer to. In addition, a drying device 51 is in Fig. 2 provided by means of the embossed wrapping material strip 33 is dried. This is followed downstream by a guide 63, by means of which in particular a lateral guidance of the wrapping material strip is made possible so as to regulate or specify the lateral position of the wrapping material strip, in particular relative to the lateral position of a further wrapping material strip 52.

The guide 63, the in Fig. 2 can also provide a limitation of sagging of the wrapping material strip 33 downwards. For example, this can be provided a base, which is schematically in section in FIG Fig. 2 is indicated, and which is an elongated ellipse.

In order in particular to bring the lateral position of the embossed wrapping material strip 33 more precisely in line with the lateral position of the further wrapping material strip 52, a further guide 63 'is provided, which is particularly preferably on the outer wall or an outer frame, or with the first Page 91 of the insertion device 30 coincides or aligned, is attached. As a result, a defined position of the second guide 63 'is provided, which is adjacent to the format device 42 and in the inlet region of the format device 42 and adjacent thereto. In particular, this is a very precise guidance of the embossed wrapping material strip 33 possible.

The embossed wrapping material strip is then placed on a further wrapping material strip 52 in the stranding machine 40, and then wound in a format device, not shown, around the filter tow strip 11 in the format device.

The wrapping material strip 52 is glued on the adhesive side 53 by means of a gluing device 54. This results in a secure connection of the wrapping material strip 52 with the embossed wrapping material strip 33. The wrapping material strip 52 is correspondingly deflected by means of the deflecting roller 62.

Fig. 3 schematically shows a plan view of the guide 63 '. There is provided a guide body 70 in the form of a cylinder, which may be mounted with a holder, for example on the wall of the first side 91 of the insertion device 30. On the guide body 70, two cheeks 71, 72 are provided, which are displaceable in the longitudinal axial direction of the guide body and can be determined by means of screws 73, 74, for example. The guide body 70 may be formed both as a cylinder and as an ellipse.

As in Fig. 2 can be seen, the top of the guide roller 62 is aligned with the top of the guide body 70 and the embossing rollers 34 and 35. This avoids that a tension on the guide body 70 is applied to the embossed wrapping material strip 33, possibly by means of Embossing would be reduced again.

In the area between the format inlet of the strand device 40 and the embossing device 36, the embossed wrapping material strip is kept as tension-free as possible by means of the tensile force adjusting device 65. Any guides for the wrapping material strip between the embossing device and the format inlet of the strand device 40 should in particular also lead the wrapping material strip as free of tension as possible.

As wrapping material strip is paper, especially crepe paper.

The embossing rollers have a corresponding geometry, for example in the form of a matrix with a male part, which are substantially complementary to one another. These should not completely squeeze the wrapping material strip when embossing, but should keep areas free for stretching. The roll circumferences should not share a common divider to prevent wear patterns.

The gap size of the inlet finger of the format device of the stranding machine should be slightly larger than usual in the production of filters with at least partially embossed wrapping material strip in order to avoid smoothing out the embossing.

The invention minimizes some sort of floating of the embossed wrapping material strip over another wrapping material strip. For this purpose, a corresponding guide is provided which is formed at the output of an embossing device or at the output of a slide-in device or process unit of a slide-in device and adjacent to or adjacent to a Forming device of a stranding machine is arranged.

Above, the invention has been explained with reference to a single-lane strand machine. For a two or more web stranding machine, for example, wider embossing rolls may be used and a wrapping material strip may be embossed that is twice or more than one strand wide. After embossing, the wrapping material strip may be longitudinally cut into two or more strips and fed to the respective strands. It can also be prefabricated, i. precut, wrapping material to be processed. In multi-lane strand machines then multiple guides can be provided.

All mentioned features, including the drawings alone to be taken as well as individual features that are disclosed in combination with other features are considered alone and in combination as essential to the invention. Embodiments of the invention may be accomplished by individual features or a combination of several features.
