The exemplary embodiments in the drawings deal with the production of cuboid (Cigarette) packs 10 with a conventional outer wrapper made of thin, clear film. The packs 10 can be of the hinge-lid type (Fig. 13) or soft cup. But there are also other types of packs provided with an outer covering.

The outer wrapping surrounding the pack 10 on all sides is made by a blank 11 formed, which completely surrounds the pack. In a facing end wall, The upper area of the pack 10 is the outer covering or the blank 11 with a provided all around tear strip 12. The tear strip 12 is on one outer end with a detectable handle end 57, which is marked by a color 58 is marked.

The packaging machine for attaching the outer wrapper to the packages 10 processes a continuous film web 13 made of thin, tearable film. Of this the blanks 11 are cut off in the region of a blanking station 14 and sent to the Hand packs of 10. The film web 13 is continuously activated by one Pulled off Bobine 15. A replacement bobbin 16 is available in each case.

The film web 13 is a plurality of deflection rollers and a compensation pendulum 17 out. The latter enables compensation in the event of an increase or reduced conveying speed of the film web 13.

The tear strip 12 is made of a suitably designed continuous material strip 18 separated. This is also subtracted from a strip bobbin 19. Preferably the material strip 18 is coated on one side with an adhesive, the one Connection of the material strip 18 or the tear strip 12 separated therefrom enables with the film web 13 by gluing.

The packs 10 coming from a packaging machine are on a Packing web 20 fed to the cutting station 14. Here is the film from the 13th separated blank 11 held ready in an upright plane, by suction belts 21. The respective pack 10 is cut across the plane of the blank being kept ready 11 conveyed through, the blank 11 with a U-shaped envelope Pack 10 carried by this and both inserted into a folding turret 22 become. On the opposite side, the cut 11 or Packings 10 provided from the outer turret 22.

The tear strip 12 can be in various ways with the film web 13 or Blank 11 can be associated. So it is possible to use the continuous strip of material 18 lead to the film web 13 and connect to it. On Separating unit 23, each with a rotating knife and a fixed counter knife then also cuts the tear strip 12 from the material strip with the blank 11 18 from (solution according to FIG. 2 and FIG. 5).

As an alternative it is provided that of the (free) material strip 18 with respect to the Correctly formed tear strips 12 separated and then positioned exactly be applied to the film web 13. The in the area of the separation unit 23rd In this case, the cut is carried out between the ends facing each other Adjacent tear strip 12 executed (solution according to Fig. 4 and Fig. 7).

A special feature is that the material strip 18 for producing the tear strips 12 is provided with at least one imprint. This will applied by suitable printing units in the industrial production of the material strip 18. These can be markings, namely colored or black ones Brands. Advantageously, the material strip 18 is at precise positions at intervals markings for the end of the handle. Alternatively or additionally can print with content or decorative design attached be, for example, manufacturer information etc. In addition, according to a further development also the film web 13 with prints, markings or the like provided, which are also attached precisely in the manufacture of the film web 13 become. Here, too, it can be informative or decorative prints, in the simple case, however, act as print marks 25.

It is now a question of, on the one hand, the tear strip 12 with regard to the printing on to position the exact relative position to the blank 11 and on the other hand a correct one Make a separating cut, i.e. one with regard to the prints and markings produce correctly formed blank 11.

For this purpose, the existing prints, markings etc. are scanned through optoelectronic touch sensors. The sampled data about any relative positions the prints, markings etc. are used to adjust the film web 13, the material strip 18, the tear strip 12 or the separating cut.

In the embodiment according to FIG. 2, the one provided with the material strip 18 Foil web 13 assigned a print mark reader 26, the prints or markings 24 detected in the area of the material strip 18 and recognizes any incorrect positions. The print mark reader 26 is equipped with a known evaluation unit (not shown) connected. This in turn controls the conveying movement of the film web 13 as required any deviations found. These relate to the exemplary embodiment according to Fig. 2 (and Fig. 5) the correct positioning of the separating cut by the separating unit 23. Misalignments are caused by a change in the drive of the film web 13 balanced. For this purpose, the film web 13 is adjacent in the area conveyed to the cutting station 14 by drive rollers 27, 28, at least of which a drive roller 28 is connected to a controllable drive, namely a Servomotor 29. This changes in accordance with that recorded by the print mark reader 26 If necessary, data the advance of the film web 13 in one or other direction with the consequence of a correspondingly changed positioning of the Separating cut. The drive roller 28 is for this purpose with a suitable outer coating made of a material with increased frictional resistance, for example rubber material, Plastic or silicone provided.

In the solution according to FIG. 3, in addition to the material strip 18, there is also the film web 13 provided with printing, namely, for example, with printing marks 25. These are recognized by an associated print mark reader 30, which here on the Print mark reader 26 is positioned opposite side. The print mark reader too 30 is connected to the evaluation unit. By the interaction of the print mark readers 26 and 30 it is possible, in addition, the relative position of the tear strip 12 or the material strip 18 on the blank 11 or the film web 13 and adjust if necessary.

For this purpose, the conveying movement of the material strip 18 before the connection controlled with the film web 13. The material strip 18 is around a first conveyor roller 31 and then guided around a second conveyor roller 32. Adequate The material strip 18 is deflected in the region of the conveyor rollers 31, 32 in each case caused by two deflection rollers arranged on both sides of the conveyor rollers 31, 32.

The conveyor roller 31 is connected to a controllable drive, namely a Servo motor 33. This can be controlled by the print mark readers 26 and / or 30. The Servo motor 33 and the conveyor roller 31 cooperate with the conveyor roller 32, the is driven by a motor 34, which is also a servo motor can act. Both conveyor rollers 31 and 32 are formed on the surface so that they can transmit a driving force on the material strip 18. The servo motor 33 can be used to change the relative position of the tear strip 12 or this attached labels (mark 24) can be controlled. In particular malpositions are compensated for by the fact that the conveying roller 31 also has is driven slightly lower speed than the conveyor roller 32, so that a slight stretching of the material strip 18 with a corresponding slight change the position of the prints, markings 24, etc. is effected. A Adjustment in this way is done in several steps or over a period of time carried out in small steps so that the stretching or stretching of the material strip 18 is insignificant.

Fig. 4 and Fig. 7 show a solution in which the tear strips 12 from the material strip 18 separated and then transferred to the film web 13 in the correct position become. For this purpose, the film web 13 is guided over a suction roller 35, which is the individual tear strips 12 also transported along the circumference and to the film web 13 creates. The adhesive layer of the tear strips 12 is directed outwards.

A suction unit is arranged upstream of the suction roller 35, namely a rotating knife roller 36, the one in cooperation with the circumference of the suction roller 35 as a tear strip 12 serving section separates the material strip 18 and to the suction roller 35 passes.

In this embodiment, tear strips 12 or strips of material 18 and Foil web 13 provided with prints, markings or print marks, which one on top of the other are to be coordinated. For the correct cut in the area of the cutting station 14, the print mark reader 26 is assigned to the markings 24. The printing assigned to the film web 13, for example the print mark 25 Print mark reader 30 controls a drive of the material strip 18, specifically a conveyor roller 37, which is driven by a controlled servo motor 38. By steering rollers sufficient wrap around the conveyor roller 37 is ensured. This is in The conveying direction of the material strip 18 is positioned immediately adjacent to the knife roller 36. The conveyor roller 37 can according to recognized misalignments of the printing driven in the sense of a higher or a reduced conveying speed his. If the conveying speed is lower, small, negligible ones may be required Gaps occur between the tear strips 12 lying against the film web 13. Those involved in the conveyance of the material strip 18 or the tear strip 12 Organs, namely the suction roller 35 and the knife roller 36, are machine-controlled driven at constant speed. Because in the area of the knife roller 36 by changing the conveying movement of the material strip 18 slightly Slip can occur and the material strip 18 with the glue Bears against the circumference of the knife roller 36, this is with a special Provide surface coating, especially made of silicone.

A special feature are measures for a two-lane operation with simultaneous Production of two blanks 11 (with tear strips 12). The cutting station 14 two foil webs 13 are spaced apart in the same plane in the transverse direction conveyed. The two film webs 13 are run through by a double web 39 central separation with a fixed knife 40 and spreading generated.

Analogously, the two film webs 13 are two material strips 18 with a corresponding one Distance from each other.

5, a double strip 41 is available a double-width strip of material. It is printed in full width provided, for example with markings 24, such that after division of the double strip 41, each material strip 18 has the markings 24. The Double strip 41 is over deflection rollers of a compensating pendulum 42 of a separation station fed. In its area, the double strip 41 is severed in the middle a rotating circular knife 43 which works together with a support roller 44. The separating cut is carried out in the region of a circumferential groove of the support roller 44. By feeding the formed (two) strips of material 18 to further, in axially spaced from each other deflecting rollers spread the Material strips 18 so that they are conveyed at the required distance from each other.

Each film web 13 can have a monitoring device with print mark readers 26, 30 be assigned in the described embodiment, but it has been recognized that a sufficiently precise control of both film webs 13 with respect to the tear strips 12 is possible if only one film web 13 is checked. This applies to the exemplary embodiment 5 for the markings made on the tear strip 12, but also for the prints applied to the film web 13 according to FIGS. 6 and 7, for example print marks 25, which are accordingly off-center on the double track 39 are attached and after the separation only on one of the two film webs 13 are present.

Fig. 6 shows a perspective view of the material flow for the embodiment 3, that is, with a control of the movement of the material strip 18 or Double strip 41 through the conveyor rollers 31 and 32. The central severing of the Double stripe 41 takes place after the compensating pendulum 42, namely in the 5 described manner.

FIG. 7 is the perspective illustration of the exemplary embodiment according to FIG. 4, however without representation of the conveyor roller 37. That of a common bobbin, namely Strip bobbin 19 double strips 41 removed before the tear strips are separated 12, that is, divided in the conveying direction in front of the knife roller 36. The strips of material formed 18 are spaced apart and separate knife rollers 36 and subsequent suction rollers 35 fed, as in the context described with Fig. 4.

8 to 10 show special features with regard to the provision of material strips 18 for the production of the tear strips 12 in double-lane operation. It will two separate strips of material 18 at a time from a special strip bobbin 45 or deducted from a double bobbin with two single bobbins 46, 47 (FIG. 10). In the embodiment according to FIG. 9, as shown in detail in FIG. 12, there are two separate, printed material strips 18 directly adjacent and in more exact Relative position wound on the common strip bobbin 45. The two strips of material 18 are placed side by side at the same time and without changing the relative position unwound from the strip bobbin 45 and then separated from each other until for precise transfer to the assigned film webs 13.

The two closely adjacent material strips 18 initially run over a deflection roller 48, which is axially parallel to the strip bobbin 45 on a movable support, namely a one-armed, curved or angular support lever 49 is mounted is. This is fixed at one end remote from the deflecting roller 48 Pivot bearing 50 mounted. The deflection roller is adjacent to the (variable) circumference the strip bobbin 45 is supported or lies against the circumference thereof.

The two strips of material 18 are deflected by the deflection roller 48 guided a first spreader, namely over two arranged at a short distance from each other Spreading rollers 51, 52 on a support rod connected to the support lever 49 are stored.

The two strips of material 18 then run - still at a short distance from one another - About a double role 53 as another management body. The one with two separate ones Raceways provided double roller 53 is above the strip reel 45 and the Support lever 49 and also above a compensation pendulum 54 with a plurality arranged by relatively movable pendulum rollers. Between the pendulum rollers of the compensating pendulum 54, fixed guide rollers 55, 56 are mounted. These have depressions arranged along the circumference for guiding the two Material strips 18 with increasing distance from each other. Then follow in the direction of conveyance two guide members with pairs of guide rollers 59, 60. These are rotatable Bearing on fixed axes and with increasing distance in the conveying direction arranged from each other, so that there is a spreading of the two strips of material 18 is. The guide rollers 59 are in a lower area and the guide rollers 60 stored in an upper area, so that in each case a large wrap angle the material strip 18 is given. This also applies to the positioning of the in Direction of conveyance in front of deflection and guide elements.

The two material strips 18 are in the region of a deflecting roller of the (two) film webs 13, namely in the area of a merging roller 61 on the outside of the film webs 13 created. For this purpose is immediately adjacent, namely above the Merging roller 61 a guide for the two strips of material 18 attached, which guides exactly the required distance between the two strips of material 18th from each other. These are two with a guide groove Guide rollers 62 on a common support rod. Otherwise, the device 8, 9 in the sense of the examples described above, in particular corresponding to FIG. 2.

A special feature is shown in FIG. 10. For two-lane operation, there are two Material strips 18 wound on two separate bobbins, namely single bobbins 46, 47. The winding structure of the material strips 18 is identical, so that in synchronous controlled drive when unwinding the two strips of material 18 always parallel be performed at a specified distance from each other. A special feature according to Fig. 10 is that the two individual bobbins 46, 47 on a common support member are wound, namely on a common, sleeve-shaped bobbin core 63. Die the two individual bobbins 46, 47 are independent units with a small distance between them wound. In the manufacture of the individual bobbins 46, 47 on a common Bobbin core 63 is expediently created a matching winding structure, so that the two strips of material 18 parallel and in a corresponding relative position can be subtracted from markings from the two individual bobbins 46, 47. The Bobinenkem 63 rests with a usual center opening on a trunnion 65, which is driven in rotation.

The guide members for the two strips of material 18 are analogous to FIG. 9 formed so that the side view of FIG. 8 also on the embodiment 10 applies. There are only the spreading rollers 51, 52 in one of the positions Strips of material 18 at the appropriate distance from each other on the common Support rod arranged and on this according to the winding structure forth. Furthermore, the double roller 53 is broken down into two in a corresponding manner Distance from each other rollers 64. These bring about an alignment of the when unwinding across the width of the individual bobbins 46, 47 material strips 18 to a certain, parallel winding direction. The guide rollers 55 and 56 are in with provide larger spaced guide grooves. Corresponding are also the guide rollers 59 and 60 in the same, the distance between the two strips of material 18 spaced from each other. The guide rollers 62 are designed and arranged in the same way as in the embodiment 9. This also applies to the rest of the device.

The special design of the bobbins and their handling according to FIGS. 11 and Fig. 12 can also be used with other (narrow) material webs, if two or more webs are to be processed simultaneously and synchronously.
