The invention relates to the production of blanks from a packaging material.

The invention will be explained with reference to various examples of a collar 10 for a cigarette pack, for example of the Hinge-Lid type. In such packs is a collar 10 arranged in a box part of the pack so that it protrudes upward from the box part. Further, the package includes a lid which is pivotally hinged to the box part and which includes the collar in the closed position.

The variants of a collar described below 10 correspond to corresponding devices for producing such blanks, which are also described accordingly. It is understood that the devices of course not only in the manufacture of collars 10 can be used for cigarette packs, but also in other blanks. In that respect, the reference to the collar 10 purely exemplary.

All the embodiments in common is that the collar 10 from a continuous material web 11 be cut out. This is done by a transverse separating cut. Furthermore, further processing steps can be performed, in particular embossing, punching, punching, grooving, scribing the material web 11 or of the collar 10 include. Also conceivable are processing steps such as printing, coating or the like. All processing steps are carried out by appropriate processing facilities that are part of a processing apparatus 12 are. The construction of the processing apparatus 12 will be described later, after some examples have been explained in terms of the basic structure and the basic arrangement.

A first embodiment is in 1 to 3 shown. The collar to be made 10 is in 3 shown. The collar 10 has a collar front wall 13 , as well as two lateral thereto arranged collar side walls 14 . 15 on both sides of the collar front wall 13 are arranged. In the area of a collar top is a recess 16 educated. In the area of a collar bottom there is a similar approach 17 , Because recess 16 and approach 17 have the same shape and dimensions, the collar 10 waste-free from the material web 11 be cut out.

Furthermore, the collar faces 10 creases 18 or scratches in the longitudinal direction of the material web, over the entire length of the collar 10 run continuously. Furthermore, the collar has 10 in the area of the collar front wall 13 below the recess 16 an imprint 19 on, as well as two C- or U-shaped punches 20 side of the recess 16 in the transition between the collar front wall 13 and the respective collar side walls 14 . 15 ,

The production of such a collar 10 takes place as shown schematically in 2 shown. Accordingly, first is a pair of feed rollers 21 provided, between which the material web 11 through in the direction of the arrow 22 is encouraged. The web 11 arrives in this way in the working area of a knife roller 23 that with a counter-roller 24 cooperates. In the area of the rotating driven knife roller 23 are all embossing, punching and separating cuts, and the grooving 18 on the collar 10 appropriate. For this the knife roller has 23 in the usual way on transverse knives, for singling the collar 10 from the material web 11 by means of a transverse to the longitudinal direction of the web 11 directed separating cut. The knife roller 23 has in the longitudinal direction of the web 11 acting organs for the formation of creases 18 , Further, on the knife roller 23 also arranged a stamping member for attaching the stamping 19 on the collar.

The drive of the feed rollers 21 takes place in the present exemplary embodiment by means of its own servo drive 25 , The knife roller 23 is preferably coupled to the drive of the packaging machine. It is also conceivable that feed rollers 21 and knife roller 23 are geared together, as in the following embodiments.

The second embodiment according to 4 to 6 differs from the embodiment according to 1 to 3 in that the collar 10 a full-surface imprint 19 having. For this purpose, the feed rollers 21 formed as embossing rolls, whereas the knife roller 23 Accordingly, no embossing member must have, but only means for performing the separating cut and for attaching the creases 18 or punching 20 ,

As already mentioned, the feed rollers 21 as well as the knife roller 23 by means of a gearbox 26 be coupled or the feed rollers 21 can by a servo drive 25 be driven separately, as in the previous embodiment.

In a third embodiment according to 7 . 8th and 10 becomes a collar 10 manufactured, as in the embodiment according to 1 to 3 , However, the attachment of the embossing takes place 19 not in the area of the knife roller 23 but in the area of an additional embossing roll 27 that with another counter-roller 24 works together and the between the feed rollers 21 and the knife roll 23 is arranged. All rollers are in this case via a common transmission 26 coupled together. Alternatively, it is of course again conceivable that the feed rollers 21 via a separate servo drive 25 are driven.

Another alternative to the collar 10 according to 10 is in 9 shown. Also the collar shown there 10 can with a device according to 8th getting produced. The embossing roller 27 but in this case is not for the attachment of a localized coinage 19 but rather for the attachment of a partially full-surface embossing 19 , Only a narrow strip-shaped area above the approach 17 is not shaped. It is also conceivable here, the attachment of a full-scale imprinting 19 as in 6 ,

In the next embodiment according to 11 to 13 comes a collar 10 or a material web 11 used, which applied a pre-processing printing 28 exhibit. The printing 28 is in the present case on the one hand of a print mark and on the other a decorative element together, which follows the contour of the collar top edge and is arranged at a small distance from the free edge of the collar top edge. Conceivable, however, are other decorative prints. By the way, the collar is 10 as in the embodiment according to 9 designed, so with a substantially full-surface imprinting 19 just a narrow strip above the neck 17 leaves free.

The associated processing apparatus 12 initially has a pair of feed rollers 21 that have their own servo drive 25 are driven. The feed rollers 21 downstream is a print mark reader 29 , On the print mark reader 29 follows a pair of embossing rollers 27 for attaching the embossing 19 and finally a knife roller 23 with counter-roller 24 , The embossing rollers 27 are with the knife roller 23 or the counter-roller 24 by means of a gearbox 26 coupled.

In the 12 The device shown works as follows: With the help of the print mark reader on the web 11 attached imprints 28 , in particular the print mark, scanned. According to the location of the imprints 28 or the print mark are the feed rollers 21 so controlled that the embossing 19 positionally correct to the print mark or the printing 28 is attached. The unembossed area or stripes on the collar 10 allows a modulation of the web 11 because the material web 11 free in this area by the embossing rollers 27 passes through. In the area of the knife roller 23 Finally, the creases 18 as well as the punching 20 attached and carried out the transverse separation cut.

In the last embodiment according to 14 to 16 becomes a collar 10 made, instead of the embossing 19 of the embodiment according to 3 at the same place a punching or perforation 30 having. The perforation 30 is in the range of a first embossing roller pair 27 appropriate, which also for feeding the material web 11 serves. This is followed by a knife roller 23 with a counter roll 24 in whose area the creases 18 on the material web 11 be attached. In the area of another knife roller 23 with counter-roller 24 are the transverse cuts for singling the collar 10 appropriate.

The embodiments described above are intended to illustrate that for the production of collars 10 Various processing steps are required, which can be done in the range of several processing stations or processing facilities. It turns out that machining devices can be designed to carry out only one machining step or, alternatively, the machining steps can be distributed to a single or several machining stations.

17 shows an overview of an apparatus for producing such collar 10 , There are two bobbins 31 shown, of which in each case a material web 11 is withdrawn and in a so-called collar apparatus 32 is directed. In the collar apparatus 32 is the processing apparatus 12 with the processing devices described above.

The processing apparatus 12 is composed of processing facilities as in 8th shown, or for the production of collars 10 according to 9 , The processing apparatus 12 according to 18 thus contains at a first position a pair of feed rollers 21 for conveying the material web 11 through the processing apparatus 12 , It then follows an embossing roll 27 for attaching the embossing 19 on the material web 11 , In third position follows a knife roller 23 with longitudinal and transverse knives 33 for applying the creases 18 and for performing the transverse cuts.

19 shows a side view of the processing apparatus 12 , Accordingly, is on a machine housing 34 , which is only partially shown, a storage means 35 arranged for the assembly of several processing facilities 36 . 37 . 38 is formed at predetermined positions. The positions are in the present case by crossbeams 39 specified. Here, however, other constructive measures can be implemented to ensure that the positions of the processing equipment to each other by the bearing means 35 are predetermined. This facilitates the alignment of the processing equipment to each other.

In the present case, the first processing device contains 36 the feed rollers 21 , In the middle, second processing facility 37 there is the embossing roller 27 , In the third processing device 38 is the knife roller 23 arranged, as well as a pair of accelerator rollers 40 , to remove the isolated collar 10 ,

Out 20 results in the construction of the transmission 26 for coupling the various processing devices 36 . 37 . 38 , The various intake, embossing and knife rollers or their counter-rollers are each on shafts 42 rotatably mounted. The rotation of the pairs of rollers is in each case by intermeshing gears 41 coupled, interlocking on one side of the waves 42 the rollers are arranged. To transfer the driving forces are between the processing facilities 36 . 37 respectively. 37 . 38 Intermediate gears 43 provided with the gears 41 the processing equipment 36 . 37 and 38 are engaged. The gears 41 . 43 together make up the gearbox 26 for coupling the different rollers together. Of importance is also the distance 44 between the processing facilities 36 . 37 . 38 , This distance 44 corresponds in each case to a multiple of the repeat length, ie the length of the material web 11 at one revolution of the respective rolls. Unless, for example, in the production of shorter collars 10 a change in the repeat length is required, so must the distance 44 between the processing facilities 36 . 37 and 38 be adjusted. This is for example in 21 shown. The intermediate gears 43 are on swivel levers 45 stored, thereby reducing the distance 44 between the processing facilities 36 the position of the idler gears 43 is changed without the coupling by means of the transmission 26 is interrupted.

The adjustment of the distance 44 between the processing facilities 36 . 37 . 38 preferably takes place in that the storage means 35 is exchanged for another storage means 35 , which is a corresponding location of the processing facilities 36 . 37 . 38 pretends. In this way, no or only a slight adjustment of the position of the processing equipment 36 . 37 . 38 required.
