The drawings deal with the preferred area of application, namely the design and manufacture of cigarette packs 10. These consist of the actual packaging container to include the contents of the pack. Two are preferred Examples shown, namely on the one hand a "hard pack" made of thin cardboard, namely a hinged box 12 (Hinge Lid Pack) in Fig. 1 and Fig. 2 and on the other hand one "Soft pack", namely a cup pack or a cup 65 in Fig. 8.

The content of a cigarette packet 10 consists of a cigarette group, which is surrounded by an interior cut, predominantly from tinfoil (not shown). This unity forms a cigarette block 11 as the contents of the pack. The cigarette pack is on the outside 10 surrounded by an outer casing 13, which a transparent or clear plastic film or cellophane is formed.

The hinged box 12 is designed as standard, exists namely from a (lower) box part 14 and an (upper) Lid 15. Box part 14 and lid 15 are in the area common rear wall over a transverse hinge line connected with each other.

The blank for the box part 14 is designed such that narrow, upright side walls 16 consist of two layers, namely side lobes completely or partially overlapping one another 17, 18. These are bonded together. Analogous lid side walls 19 are formed, namely with two each other cover side flaps 20, 21 also covering

Inside the box part 14 is one of them partially protruding collar positioned, of which a collar side tab in Fig. 2 22 is shown. The one from the box part 14 protruding parts of the collar or the side flap of the collar 22 is through the lid 15 in the closed position of the hinged box 12 includes.

The lid 15 forms on the front of the pack or hinged box 12 opposite to a box front wall Butt or closing edge 23. This also extends in the region of the opposite side walls 16 of the Hinged box 12. A side closing edge 24 is common diagonally, namely to the back of the hinged box 12 rising towards (Fig. 1).

In the present example, the package is thin rectangular blank made of paper, namely with a (Control) banderole 25. This is in the area of the side wall 16 and lid side wall 19 positioned. The side closing edge 24 is covered by the band 25.

In the present exemplary embodiment, the band is 25 between the outside of the side wall 16, 19 on the one hand and the outer casing 13 on the other hand. A special feature is that the band 25 on the one hand with the Hinged box 12 is connected and on the other hand with (the inside) the outer wrapper 13. As a lanyard is here one glue layer 26, 27 is provided, that is, on both Sides of the banderole 25. These are full-surface Glue layers 26, 27. Instead of a full-surface glue layer 26, 27 other glue patterns, for example glue dots, can be applied become.

The outer casing 13 is with a tear strip running all around 28 provided. This is on the inside of the outer casing 13 attached. A tip 29 is used to detect the Tear strip 28 at one end and for tearing the tear strip 28 while cutting through the outer casing 13.

The tear strip 28 also runs in the area of the banderole 25. As can be seen from FIG. 2, the tear strip is 28 between the band 25 on the one hand and the facing side or wall of the hinged box 12, on the other hand, in the present case on the side wall 16 of the box part 14. The tear strip 28 is through the glue layer 26 on the Side wall 16 fixed and connected to the band 25 at the same time. When the tear strip 28 is actuated, the banderole becomes 25 severed in the middle. The tear strip 28 runs in the present case at the level of the closing edge 23 or below the oblique side closing edge 24.

In the manufacture of cigarette packs 10 of these or others Execution is carried out so that the print carrier or the band 25 on the inside of a blank for the outer wrapping 13 is attached (Fig. 3). The band 25 lies on the inside of the blank of the outer casing 13 and tear strip 28 (inside) on banderole 25. Alternatively the full length of the tear strip 28 can be made directly on the blank the outer casing 13 abut. With this version the tear strip 28 is covered on the inside by the band 25. In this alternative, the band 25 remains in the removal the outer casing 13 with the aid of the tear strip 28 intact on the hinged box 12.

The outer casing 13 encloses the hinged box 12 on all sides. The blank for the outer casing 13 accordingly forms a front wall 30, an equally large rear wall 31, a middle one Side wall 32 and outer side wall tabs 33, 34. The latter together form an opposite side wall 32 Side wall of the outer casing 13 by overlap and connection with each other by gluing or by thermal sealing. Edge strips of the blank of the outer covering 13 form end-folding tabs 35 and bottom folding flap 36.

The blanks designed according to FIG. 3 are of a continuous material web 37 made of thin, transparent Film material separated. The banderoles 25 are opened beforehand the material web 37 applied, and exactly accordingly the position within the cigarette pack 10, so here in Area of a side wall 32. Thereafter, also during the continuous transport, the continuous, self-adhesive tear strip 28 applied. From the material web prepared in this way 37, the blanks are cut off at a predetermined position.

Details of a device for manufacturing or preparing the material web 37, the blanks for the outer casing 13 and attaching them to the (cigarette) packs 10 are shown in Figs. 5-7.

The material web 37 is preferably continuously of one Pulled off Bobine 38. The material web is guided over deflection rollers 39 37 promoted to the area of a first glue station 40. Here glue is used to fix the band 25 onto the material web 37 brought, namely the (rectangular or strip-shaped) Glue layer 27. The precise position with glue spots or Material layers 37 provided with glue layers 27 then enter a transfer station 41 for placing the individual banderoles 25 onto the material web 37 in the area of the glue pattern or the glue layer 27.

The material web 37 then arrives in a further glue station 42. In their area, glue is applied to the free side of the banderoles 25 applied, namely in particular the glue layer 26. The material web 37 then passes through a thread station 43. In this becomes the continuous tear strip 28 on the material web 37 hung up. The tear strip 28 is one Strip bobbin 44 subtracted.

The one provided with the banderoles 25 and the tear strip 28 Material web 37 then runs through a cutting unit 45 through it. Here, blanks according to FIG. 3 are made from the material web 37 separated and in an upright level for takeover held ready by the packs or hinged boxes 12.

In the first gluing station 40, an (approximately) horizontal conveying path of the material web 37 from above glue applied, namely the glue layer 27. For this purpose, a glue nozzle 46 activated. This is with a slit-shaped nozzle opening Mistake. During a precisely controlled opening time becomes a rectangular as a result of the conveying movement of the material web 37 Glue pattern, namely the glue layer 27, applied.

The glue nozzle 46 is part of a glue unit 47 that is movable is mounted on a machine frame, namely on a supporting wall 48. The glue unit 47 can be removed from the glue position (FIG. 6). withdrawn, by pivoting along one Swivel bearing 49. To actuate the glue unit 47 in the sense a cylinder 50, which is on the supporting wall, serves for a pivoting movement 48 attached and its piston rod with the glue unit 47 or a swivel arm of the same is connected.

The transmission station 41 is designed in a special way (Fig. 7). The banderoles 25 (or other blanks) are taken from a banderole magazine 51. On the open bottom of the banderole magazine 51, a removal organ is effective, namely a reel 52 known in principle. This removes a single banderole 25 by a rolling movement from the banderole magazine 51. The unwinder 52 is on a lower one Removal opening of the band magazine 51 through a Parallelogram linkage 79 reciprocable. The dispenser itself is on a handlebar 80 as part of the parallelogram linkage 79 attached.

The removed banderole 25 is transferred to a transmission device, namely to a transfer roller 53. This is longitudinal of the circumference with radially directed, open suction bores 54 provided for gripping a banderole 25 and for transporting the same by turning according to arrow 55. The transfer roller 53 applies the banderole 25 to the material web 37, specifically in exact, packaged position. The rectangular banderoles 25 extend with their longitudinal extent in the axial direction the transfer roller 53.

The material web 37 is used to take over the banderole 25 a backup roller 56 guided opposite to the transfer roller 53 is positioned. The transfer of the banderole 25 to the material web 37 takes place in the area of the support of the Material web 37 on the support roller 56.

To support the handover process is in this area a stationary scraper 57 is provided. This is approximately tangential directed to the circumference of the transfer roller 53 and so trained that the band 25 with the in the direction of movement front area runs onto the scraper 57 and thereby lifted from the circumference of the transfer roller 53 and on the material web 37 is pressed. Furthermore are in this Area controlled the suction holes 54 so that they with Pressure and thereby the solution of the banderole Support 25 of the size of the transfer roller 53.

The material web provided with the band 25 is then the second glue station 42 supplied. In the area of an incline 58 glue is applied to the section by a glue nozzle free side of the band 25 applied. The glue nozzle 58 is Part of a glue unit, which is analogous to the glue unit 47 is formed and also moved by a cylinder 60, namely can be pivoted.

The material web 37 prepared in the manner described is then continuously in the area of the thread station 43 with the Tear strip 28 provided on the facing side of the Material web 37 is pressed and in the area of the banderoles 25 covers this.

The cutting unit 45 holds those separated from the material web 37 3 ready in a vertical plane. Upright suction belts 61 are provided for this purpose, on which the blanks lie with lateral areas. The Folded boxes conveyed on a horizontal packing line 12 are conveyed between the suction belts 61 in Direction towards a folding turret 62. The ready one is kept Cut taken from a folding box 12 and from the suction belts 61 detached. When inserting a hinged box 12 with outer covering 13 in a pocket 63 of the folding turret 62 the cut of the outer casing 13 is U-shaped Pack or hinged box 12.

The folding turret 62 is then rotated in cycles. Go through it the pockets 63 folding stations (not shown) in which the outer wrapping 13 is folded. Opposite the insertion side the finished cigarette packs 10 from the Folding turret 62 pushed out into a packing tower 64. Then the finished cigarette packs 10 are further processed fed, especially the formation of containers.

When taking a ready-made blank of the outer casing with you 13 by a hinged box 12 and when inserted in a pocket 63 of the folding turret 62 is the cut relative so positioned to the hinged box 12 that an area for Formation of the side wall 32 of the outer casing 13 on the facing or side wall 16 lying in the direction of movement and cover side wall 19 abuts. The in this embodiment provided on the free side with glue (glue layer 26) Banderole 25 is also included in this transfer process the hinged box 12 connected, namely to the side wall 16/19.

Another embodiment of a cigarette pack 10 is shown in Fig. 8. It is a pack of the Type soft cup. The container for the package contents is there proportionately from an open cup 65 made of paper or other thin packaging material. The cup 65 is on all sides closed, except for an upper, frontal area. The contents of the pack, namely the cigarette block, protrude here 11, slightly out of the cup 65. One across connecting control sleeve 66 extending over the end face the cup 65 in this area with the package contents, namely the cigarette block 11.

The cup 65 and its contents are also covered by an outer casing 67 surrounded, which consists of a blank according to FIG. 3. Indeed is a tear strip 68 adjacent in this example to the upper end face of the outer covering 67 (forehead folding flap 35) attached.

The blanks for the outer wrapper 67 are also from separated from a continuous web of material 69.

The cigarette pack 10 according to FIG. 8 is cut to size 70 provided, which serves as a print medium, namely for information, Advertising, but also for including one in many Countries prescribed health warning. The rectangular one Blank 70 is also between the clear outer casing 67 and the actual package, namely the cup 65 arranged, with a print side facing outwards. Analogous to the embodiment described the blank extends 70 in the area of a central or inner, closed Side wall 32 of the outer casing 67. The blank 70 is however dimensioned so that a middle area over the Width of the side wall 32 extends and legs 71, 72 in the Area of the adjacent packing areas, namely the front wall 30 and rear wall 31, protrude. The blank 70 has inside the cigarette pack 10 has a U-shaped cross-sectional shape.

To produce such a cigarette pack 10, the Cuts 70 also on the material web 69 in a package-appropriate manner Position hung up, namely in the position described in the area of the side wall 32. The material web 69 is thereby prepared so that the tear strip 68 is placed first and then the blank 70 is attached. At the finished As a result, the blank 70 lies on the inside of the tear strip 68 at. When opening the package or when cutting the outer casing 67 by actuating the tear strip 68 Accordingly, the blank 70 remains intact. If only connected to the material web 69 or the outer casing 67 the blank 70 with the outer covering 67 can be removed become. But it is also conceivable that by appropriate Connection of the blank 70 permanently on the pack or on Cup 65 sticks.

The device for producing such packs or Preparing the material web 69 is analogous to that in FIG. 11 5 designed. The material web 69 is withdrawn from a bobbin 73 and fed to a thread station 74. The tear strip 68 is continuously in its area connected to the material web 69.

In the area of a transmission station 75, the individual Blanks 70 by a feed roller 76, namely in the region of the side wall 32, on the material web 69 created. The blanks 70 are on the material web 69 glue on the facing side.

The material web prepared in this way becomes a cutting unit 77 fed. Here are blanks for the outer wrapping 67 manufactured and kept ready for takeover by cup packs 65.

When inserting the cup packs 65 with a blank for the outer covering 67 in a pocket 63 of the folding turret 62 not only is the outer wrapping 67 folded in a U-shape, but also also the blank 70 attached to it during this insertion movement the legs 71, 72 also folded.

The bands 25 or blanks 70 can also be on another Place attached inside the outer casing 13 or 67 be, for example in the region of front wall 30 and / or Rear wall 31.

There are also special features with regard to the type of attachment possible. So the fixation of the bands 25 or Blanks 70 on the material web 37 or 69 can be selected that only for the duration of the folding process in the area of the cutting unit 45, 77 or the folding turret 62 a sufficient Connection is given. This is possible, for example by a glue, that is, by a layer of glue 27, which after is automatically removed for a certain time (so-called Stick-no-stick glue). A special alternative is Banderole 25 or blank 70 glue-free on the material web 37, 69 to fix, namely by electrostatic charging of the Material web 37, 69. In the device according to FIG. 11 there is a Activation element 78 shown schematically, with which the electrostatic Charging of the passing web 69 knitted becomes. The blank 70 which is subsequently placed on is cut by the electrostatic charge for a sufficient duration and with sufficient durability fixed to the web 69.

The relative position of the tear strip 28, 68 is to be selected so that - depending on the intended purpose - the banderole 25 or the blank 70 when opening the cigarette pack 10 with the help of the tear strip 28, 68 is destroyed.

The material web 37 or 69 can in the manner described Area of the packaging machine. But it is also possible a partial preparation of the material web outside the packaging machine, namely in the field of production the film web. In this case in the production of the film or the web of material, the printing medium - banderole 25 or blank 70 - already applied, namely connected to the material web by gluing. This will then wrapped in a bobbin and in this prepared version made available to the packaging machine. In the area the packaging machine is then, as usual, only the Tear strips 28 attached.
