Definitions

• the present invention relates to a method and a device for producing a package for bar-shaped smoking articles that has at least one outer layer.
• bar-shaped smoking articles is meant to include cigarettes, cigarillos, or cigars. For the sake of simplicity, mostly only cigarettes are mentioned in the following.
• a cigarette package is generally composed of an inner package that may consist of paper, plastic material, metallized paper, or synthetic paper, in rare cases also of an aluminum foil, and of an outer package that may consist of thin cardboard as it is e.g. described in WO-2010/012370 Al, or generally of plastic material, or of different layers of paper and plastic material, that offers sufficient mechanical protection, and may or not be provided with a protecting layer that protects from
• both the inner package and the outer package are supplied as blanks to the packaging machine where the cigarettes are wrapped in the inner package and introduced into the shaped outer package.
• the inner package can be embossed, i.e. satinized and provided with logos, according to known techniques.
• Supplying the two blanks synchronously to the cycle of the packaging machine requires complex synchronizing means, particularly when the inner package is being embossed and/or printed.
• increasing efforts have been made by governments and organizations to contain cigarette consumption
• the object of the present invention to provide a method and a device for producing packages for cigarettes, cigarillos, or cigars which meet the various requirements with regard to such packages without using an inner package, on one hand, and on the other hand, enable a more rational production and allow to provide the package with a large diversity of visible or virtually invisible factually, acoustically, or olfactorily perceptible signs that may also serve as authentication features.
• the term "sign" is meant to include any kind of logotypes, individual points, groups of points, colors, as well as combinations thereof which are produced by the embossing roller (s) and are visually, factually, acoustically, or olfactorily perceptible.
• embossing unit in a pinup-pinup configuration shows a roller assembly in a pinup-pindown configuration, shows a section according to line VIIIA - VIIIA in Fig. 8, shows an exemplary embodiment of a creasing roller assembly, shows a lateral view of Fig. 9, shows an exemplary embodiment of a cutting roller assembly, schematically shows a folded blank, shows a portion of cigarettes, Fig. 14 shows the package of Fig. 12 in the closed state,
• Fig. 15 shows a cigarette holder strip
• Fig. 16 shows an innerliner
• Fig. 1 shows a simplified flow chart of a possible device for producing a package for cigarettes as it is illustrated in Figures 12 and 14.
• Device 1 according to Fig. 1 comprises a foil strip reel 2 with a foil strip 3 that runs first through an embossing unit 4, then through a creasing unit 5, and finally through a cutting unit 6 in order to
• the packaging foil i.e. the foil strip 3 for producing an outer package
• a light material e.g. of paper, thin cardboard
• hybrid foils i.e. foils having multiple coatings of different materials, or of plastics foils that may be metallized or otherwise coated, or for certain applications, in certain countries where it is still allowed, a metal foil.
• this will simply be designated by the term "foil”.
• device 1 comprises a first regulating unit 8
• Work cadence P may e.g. be defined by a length of packaging foil 3 that is to be fed to the
• the packaging machine per time unit and to which operating cadence Al of embossing unit 4 has to be adjusted in the pretreatment of foil 3. Thereto corresponds an accurate positioning of embossed surface structures on each length of foil 3 that is to be supplied.
• the surface structures may be structures of the embossed signs 23S, 24S.
• Synchronizing unit 8 comprises a detection device 9 for determining the operating cadence Al of embossing unit 4. This may e.g. include an optical detection of the position of surface structures 23 that have been embossed on foil 3 in embossing unit 4. More specifically, the detection takes place on the transport path between embossing unit 4 and creasing unit 5.
• the detected operating cadence Al may subsequently be adapted to work cadence P in a positioning device 10.
• a manual and/or automated adaptation procedure may be contemplated.
• the driven roller may be temporarily disengaged from the drive in order to thus lengthen the transport path of foil 3 by a desired amount that will be in conformity with work cadence P.
• device 1 comprises a second regulating unit 11.
• Regulating unit 11 comprises a comparing device 12 that allows detecting a quantitative deviation between operating cadences Al and A2 of the embossing unit and of the creasing unit. This may e.g. be accomplished by means of an optical representation by a lamp that is arranged to irradiate the foil with light at regular time intervals in the manner of a strobe. The irradiation frequency preferably corresponds to work cadence P. In this manner, an optical representation of the relative position of the surface structures embossed in embossing unit 4 and of creasing breaks 21 a-e formed on foil 3, i.e. on blank 19 in creasing unit 5 is accomplished.
• the obtained information is subsequently used in a
• Positioning device 13 in order to adapt operating cadence A2 to operating cadence Al in such a manner that the resulting creasing breaks 21 a-e are located at the desired relative positions on foil 3.
• Positioning device 13 may e.g. be arranged for a manual and/or automated adjustment of the circumferential position of driven creasing roller 34 relative to foil 3.
• creasing roller 34 disengaging creasing roller 34 from roller drive 36 may be contemplated. In addition, this allows a demand-driven or process-dependent variation of the relative positions of creasing breaks 21 a-e on foil 3.
• Comparing device 21 may also be used for detecting the relative deviation of operating cadence A2 from work cadence P for an additional verification of the synchronization to the following packaging process. Furthermore, it is possible in this manner to obtain indirect indications of an
• another buffer unit 14b is provided downstream of creasing unit 5.
• Second regulating unit 11 is followed by a third regulating unit 15 for synchronizing the operating cadence A3 of cutting unit 6 to work cadence P.
• third regulating unit 15 comprises a comparing unit 16 that allows detecting a quantitative deviation between operating cadences A2 and A3 of the creasing and cutting units, respectively.
• the signals may be acquired in analogy to the second regulating unit.
• the thus obtained information is subsequently used in a positioning device 17 in order to adapt operating cadence A3 to
• Foil strip 3, 3b may be previously printed or unprinted. However, it is also possible to arrange a printing unit upstream of the embossing unit in order to print the foil strip in time with work cadence P.
• the regulating unit provided for this purpose is similar to the described regulating units and allows synchronizing the operating cadence of the printing unit to the operating cadence of the other units and to the work cadence.
• a station for applying odorants may be integrated into the device, in which case an additional regulating unit ensures that this station operates in time with work cadence P.
• Foil strip 3b is embossed, folded, and cut in a similar manner as foil strip 3 to obtain the blank 19b with the embossed signs 24S, creasing breaks 25, and cuts 26. It is understood that both the embossing unit and the creasing and cutting units are adapted to the width of the foil strip .
• the creasing unit is not used and the regulating units are adapted accordingly.
• the number and the design of the rollers of embossing unit 4 is largely a function of the properties of the foil strip and of the desired kind of the embossed signs. If foils similar to innerliners are being processed, one side of which is metallized or has similar properties, known

Moreover it is assumed that the foil strip is always passed between the rollers in the same orientation with respect to what will be its outside.
