Farther The invention relates to methods and apparatus for manufacturing such packs.

Cigarette packs with lifting strips for easier removal of cigarettes are known. In the package according to DE 38 06 818 A1 the lifting strip is formed as a region of an inner front wall of the inner blank by means of parallel perforation lines. The thus defined lifting strip extends with an end piece in the region of a peelable flap of the inner front wall so a flap. If this is deducted when putting the pack, a handle end of the lifting strip is exposed for actuation. In practice, such a trained Endnahmehilfe for cigarettes is inadequate, because the material of the inner blank for appropriate operations is not suitable.

In a cigarette pack according to DE 1 142 546 On the inside of the inner sheath, a separate strip of material is arranged as a lifting strip. An end portion of the strip is bonded in the region of the inner front wall below the flap with the inside of the inner blank by gluing. Opposite, namely in the area of an end wall formed by folding tabs, a projection of the strip is exposed upon removal of the flap for actuation. A lifting strip arranged in this way is a frequent cause of malfunction in the production of the pack.

Of the The invention is based on the object of a pack for cigarettes, To suggest cigarillos or similar products with one From a lifting strip existing removal aid, the manufacturing technology manageable and reliable handling by the consumer.

The lifting strip is over the full effective length provided with a particular tensile strength gain. This consists of a strip of material, with the inner blank firmly and continuously connected, preferably with the outside. The lifting strip is in the area of the inner blank by weakening lines, bounded in particular by punching and perforation lines, in such a way that one end of the lifting strip on the front side after removing a Flaps is exposed and can be detected. Alternatively, the lifting strip Part of the inner rear wall and extends to one end protruding into the front wall via a folding flap of the front wall.

The Reinforcement, in particular the reinforcing strip, is used in production on a continuous material web for the inner blank applied continuously. Thereafter, the required separation and die cuts attached under definition of the lift strip, including operating end. The of the material web separated blank may in the usual way to the package contents (Cigarette group) are folded around.

at the device according to the invention becomes a strip of material, especially self-adhesive, deducted from a strip burin and to the continuous material web for the inner blank created. Thereafter, the web passes through an embossing station for applying embossing, in particular in a Stanniolbahn (Satin), wherein the reinforcing strip the embossing is also suspended. This is followed by a punching or separating station with knives for attaching perforation and punching lines as well for separating the blank from the material web.

The illustrated in the drawings embodiments of (cigarette) packs relate to hinged boxes (hing lid packs). This type of package includes an inner wrapper made of an inner blank 10 for wrapping the package contents, namely a cigarette group 11 from a plurality of cigarettes arranged in formation, namely in rows 12 , The interior blank 10 may consist of tinfoil, paper (printed or coated) or other thin packaging material. The cigarette group 11 is preferably completely from the inner blank 10 surrounded to form a cigarette block 13 ,

The essentially cuboid cigarette block 13 sits as a package contents in an outer pack, in the present embodiment in a folding box 14 , This usually consists of thin cardboard and forms a lower box part 15 as well as a lid 16 , box part 15 and lid 16 are integrally connected together in the area of a rear, transverse line joint 17 ,

The box part 15 forms a box front wall 18 , a box back wall 19 and box sidewalls 20 , Accordingly, there is the lid 16 from the lid front wall 21 , Lid rear wall 22 , Lid side walls 23 and front wall 24 , Inside the box part 15 is a collar 25 arranged with the box part 15 in the area of box front wall 18 and / or box sidewalls 20 inside is connected. One from the box part 15 outstanding upper part of the collar 25 is in the closed position of the pack from the lid 16 includes. The collar 25 is front with a recess 26 which facilitates access to the contents of the package.

The pack comes with a removal aid for the cigarettes 12 Mistake. This consists in a lifting means for lifting at least one cigarette 12 , Specifically, it is a lifting strip 27 which is arranged and designed so that several, here three juxtaposed cigarettes 12 ( 3 ) by pulling the lifting strip 27 be lifted and are thus detectable.

The lifting strip 27 is part of the inner covering or part of the inner blank 10 , This forms according to 7 to 10 an interior front wall 28 , an interior floor wall 29 and an interior rear wall 30 , At the free end areas of inner front wall 28 and inside back wall 30 are folding flaps defined for an inner end wall 31 , The folding flaps include (trapezoidal) longitudinal flaps 32 . 33 facing each other in the area of the interior end wall 31 partially cover ( 1 ).

The lifting strip 27 preferably extends in the middle of the inner blank 10 , in its longitudinal direction and is bounded laterally by at least two preferably parallel lines of weakness, in particular by punching or perforation lines 34 . 35 , These are designed so that when detecting an end portion of the thus defined lifting strip 27 the connection to the interior blank 10 solved and the lifting strip 27 acts as an automatic organ. The width may be different, here for detecting three cigarettes juxtaposed in a front or back row 12 , The perforation lines 34 . 35 extend according to 7 . 9 over the full length or height of the inner front wall 28 , in the area of the interior floor wall 29 and along a bottom side portion of the opposite inner rear wall 30 ,

The one made of the material of the inner blank 10 formed lifting strips 27 has a particular tensile strength reinforcement. This consists in the present case of a reinforcing strip 36 at least in the area of the lifting strip 27 extends, but preferably over the full length of the inner blank 10 , The reinforcing strip 36 is preferably made of plastic and is by gluing (alternatively by thermal sealing) on the inner blank 10 attached. Advantageously, the attachment to the outside of the inner blank 10 so that the sensitive cigarettes are not affected. The reinforcing strip 36 is self-adhesive and over the full length of the interior blank 10 permanently connected with this.

The from the reinforced lifting strip 27 existing removal aid can front or back of the cigarette block 13 to be appropriate. According to 1 to 3 such as 7 and 9 is the lifting strip 27 mounted on the front, ie in the area of the inner front wall 28 , This is also provided with a conventional Abziehlappen, namely a flap 37 , This is due to a transverse weakening line, here by a perforation line 38 , in the upper part of the inner front wall 28 as well as adjacent lateral folding flap defi ned. By detecting the front longitudinal flap 32 will the flap 37 with the lid open 16 pulled out of the pack ( 2 ). The front-side cigarettes 12 are thus free with their upper area.

The lifting strip 27 extends into the area of the flap 37 and ends below the inner end wall 31 ( 7 ). A cross-sectioned cut 39 limits the end of the lifting strip 27 in the area of the flap 37 , The separation cut 39 is here arcuate, so that the end of the lifting strip 27 as a tongue-shaped end of the handle 40 is trained. The full length continuous reinforcing strip 36 is through the transverse cut 39 severed so that a substantially in the region of the longitudinal lobe 32 lying piece of reinforcing strip 36 with the flap 37 is deducted. The handle end 40 thereby lies in the region of the recess 26 of the collar 25 free ( 2 ).

Alternatively (or additionally), the lifting means may be arranged in the back of the package. In the execution according to 4 to 6 the lifting strip extends 27 over the full length of the inner rear wall 30 and the subsequent longitudinal lobe 33 the inner end wall 31 , A here also by arc-shaped separating cut 30 limited grip end 40 protrudes with a section over the longitudinal flap 33 In addition, due to appropriately contoured separating cut when separating the inner blank 10 from the material web. Opposite, namely in the area of the longitudinal lobe 32 , This creates a correspondingly formed recess 41 , The perforation lines 34 . 35 for limiting the lifting strip 27 extend in the region of the longitudinal lobe 33 , the inside back wall 30 , the interior floor wall 29 and with a short section in the area of the inside front wall 28 , The continuous reinforcement strip 36 runs from the tongue-like end of the handle 40 to the recess 41 ,

For actuating the removal aid according to this embodiment, the flap is expediently 37 away ( 4 ). This is the back longitudinal flap 33 free in the area of the face. The lifting strip 27 can be in the area of the handle end 40 recorded and dragged in the upward direction.

In a simple variant, a front lifting strip 27 in the execution according to 9 be formed, namely with a very short (curved) separating cut 39 at a distance from the perforation lines 34 . 35 ends, so in this area residual connections 42 of the material. These are when the flaps are removed 37 severed so that a tongue-like end of the lifting strip 27 or a handle end 40 corresponding 7 or accordingly 2 / 3 arises. 10 shows a simplified alternative to the example according to 8th So with back lift strip 27 , This ends blunt or with a rectilinear transverse contour in the region of the longitudinal lobe 33 , The folding flap of the inner end wall 31 namely the longitudinal flap 33 shows after removing the flap the marked end or the marked end of the handle 40 of the lifting strip 27 also in this version.

The lifting strip 27 or the reinforcing strip 36 is provided with markings indicating the direction of traction to the consumer. In the present case is a continuous series of arrows 43 on the reinforcing strip 36 printed. The perforation lines 34 . 35 consist of elongated punch cuts with interruptions as residual compounds 44 so that low power requirements are sufficient to strip the hoist 27 expose. The transverse separating cut 39 forms in the embodiments according to 7 and 8th a cross-section with the end portions of the perforation lines 34 . 35 ,

In the production of interior blanks 10 with lifting strips 27 and reinforcing strips 36 is done so that the first of the reinforcing strips 36 as a continuous strip of material on a continuous material web 45 of the respective packaging material is applied. Thereafter, the punches or separating cuts to the representation of the lifting strip 27 attached and finally a cross-sectional cut to separate the inner blank 10 ,

The above manufacturing steps are in the working process of a packaging machine, as exemplified in 11 and 12 is shown integrated. The packaging machine is used here for producing folding boxes.

In the area of a cutting station 46 are in a lower position collarbobines 47 , so wound sheets of thin cardboard for the production of the collar 25 , The collarbobins 47 are below a cigarette web 48 for the transport of cigarette groups 11 and subsequently the cigarette blocks 13 , Above the cigarette web 48 there are indoor bobs 49 of which the material web 45 is deducted. This passes through a splicing unit 50 and then enters an order station 51 for applying a strip web 52 for forming the reinforcing strips 36 , The strip track 52 is from a strip bob 53 deducted. The order station 51 consists here of a pulley 54 for the material web 45 , The deflection is about 180 °. In the area of the deflection is the strip track 52 continuously to the outside of the web 45 created due to appropriate guidance of the strip track 52 over an offset steering roller 55 ,

The unit of material web 45 and strip track 52 Then, a printing unit with at least two adjacent pressure rollers 56 . 57 fed. The pressure elements transmit pressure to the material web during transport 45 and fix the connection of the strip track 52 with this. One of the pressure rollers 56 may be formed as an embossing roll for embossing the material web 45 , especially when using Stanniol. The embossing also affects the strip web 52 ,

The prepared train 45 / 52 enters a cutting station 58 , First, in the longitudinal direction of the web 45 guided perforation lines 34 . 35 for the longitudinal limitation of the lifting strip 27 attached, here by longitudinal knife 59 which act with a counter-organ, namely a knife roller 60 , Then follow transverse cuts to limit the flap 37 that is the perforation line 38 including perforation lines to limit the grip end 40 , ie in particular the separating cut 39 by a trained cross knife 61 , Finally, a cross-sectional cut across the entire web 45 executed to the prepared inner cut 10 from the material web 45 to separate, by means of separating knife 62 , In the area of subsequent rotating suction discs 63 becomes the blank 10 held in a known manner for the acquisition by a transverse to the plane of the inner blank 10 transported cigarette group 11 ,
