The invention relates to a method for producing blanks for collars of packs for cigarettes, wherein blanks for collars, preferably lying flat, are fed to a pair of transport rollers in a transport direction along a transport plane, and the blanks are two, preferably formed by a U-shaped incision Having folding tabs for a lid brake of a pack for cigarettes, wherein the folding tabs for the lid brake are each arranged in the transition from a collar front wall to a collar side wall, according to the preamble of claim 1.

Furthermore, the invention relates to a corresponding invention according to the preamble of claim 10.

Methods and devices of this type are known from practice in different configurations. The problem can be that the folding tabs for the cover brake cannot be brought into the correct position for a variety of reasons in order to be able to fulfill their function.

Proceeding from this, the invention is based on the object of further developing methods and devices of the type mentioned, in particular with regard to measures to ensure the function of folding tabs for a cover brake. A method for solving this problem has the features of claim 1. Accordingly, it is provided that at least the folding tabs for the lid brake of one, preferably each, blank are erected during transport through the pair of transport rollers, namely by placing a folding tab on a mandrel, preferably fixed on the circumference of a rotating transport roller of the pair of transport rollers, out of the plane of the be swiveled out.

A correct erection of the folding tab for the cover brake can be ensured by the mandrel, which is preferably arranged in a fixed manner on the circumference of the rotating transport roller.

Provision is preferably made for the folding tabs for the cover brake to be pivoted about an axis when erected, which runs parallel to the direction of transport.

Furthermore, it can be provided that a continuous material web for the collars is conveyed along the transport plane and fed to a cutting device upstream of the transport roller pair, and that the material web is provided in the cutting device with separating cuts for separating blanks for collars and/or that in the cutting device for each blank, two preferably U-shaped incisions are made to form the folding tabs for the cover brake.

Furthermore, it can be provided that the pair of transport rollers has the transport roller and a counter-roller assigned to the transport roller, between which the blanks for attaching the material weakenings are passed, and that a recess is arranged on the circumference of the counter-roller corresponding to the mandrel of the transport roller, into which a Mandrel erected folding flap for the cover brake is swung in.

This solution can have the advantage that the folding tabs for the lid brake are only pivoted about the bending edge.

Furthermore, it can be provided that the blanks, which are spread out flat apart from the erected folding flaps for the lid brake, are transported through a first collar switch, in which opposite lateral edge areas of the blanks, in particular collar side walls, are pivoted transversely to the transport direction, namely by correspondingly running guide means, along which the two edge areas are each guided during transport, the erected folding tabs for the lid brake being guided by separate guide means such that the erected folding tabs are not moved back into the plane of the blanks when the edge areas are pivoted.

Provision can also be made for the collars to be transported after the first collar switch through a second collar switch, in which the opposite lateral edge regions of the blanks, in particular the collar side walls, are pivoted back transversely to the transport direction, namely into a flat, spread-out configuration with the collars upright Folding tabs for the lid brake.

Provision can also be made for the folding tabs for the cover brake to be pivoted so far relative to the plane of the rest of the blank that a partial fiber tear occurs in the material of the blank, so that the folding tabs for the cover brake can pivot back into the Level of the blank is not possible, which is preferably provided is that the folding tabs are pivoted at an angle of 25° to 45°, in particular (approximately) 35°, relative to the plane of the rest of the blank.

A device for solving the task mentioned at the outset has the features of claim 10 . Accordingly, it is provided that the pair of transport rollers is set up to erect the folding tabs for the lid brake of one, preferably each, blank, namely to swivel them out of the plane of the blank by contacting a folding tab on a mandrel, which is preferably arranged in a fixed manner on the circumference of a rotating transport roller of the pair of transport rollers .

Provision can furthermore be made for a cutting device to be arranged upstream of the transport roller pair, with a continuous material web for the collars being able to be fed to the cutting device along the transport plane, and for the cutting device to be set up to provide the material web with separating cuts for separating blanks for collars and/or or that the cutting device is set up to make two preferably U-shaped incisions on each blank to form a folding tab for a cover brake.

Furthermore, it can be provided that the pair of transport rollers has the transport roller and a counter-roller assigned to the transport roller, between which the blanks for applying the material weakenings can be passed in an embossing manner, it being preferably provided that a recess is arranged on the circumference of the counter-roller corresponding to the mandrel of the transport roller, into which a folding tab for the cover brake, which is erected by the mandrel, can be pivoted, and it is provided in particular that the size of the recess of the counter-roller is matched to the dimensions of the folding tab for the cover brake.

Furthermore, it can be provided that the recess has a front edge directed transversely to the transport direction and a rear edge directed transversely to the transport direction, which are each positioned adjacent to the corresponding sections of an incision for a folding flap when the collar is transported by the transport roller pair.

Provision can furthermore be made for the device to have a first collar switch, with the device being set up so that the blanks, which are spread out flat apart from the erected folding flaps for the lid brake, are transported through the first collar switch, in which the opposite lateral edge regions of the blanks, in particular collars side walls, are pivoted transversely to the direction of transport, namely by means of correspondingly running guide means, along which the two edge areas are each guided during transport, with the erected folding tabs for the lid brake being guided by separate guide means in such a way that the erected folding tabs when pivoting the edge areas cannot be moved back into the plane of the blanks.

Furthermore, it can be provided that the device has a second collar switch following the first collar switch, the device being set up so that the blanks are transported through the second collar switch, in which the opposite lateral edge regions of the blanks, in particular the collar side walls , are swung back transversely to the direction of transport, namely in a flat, spread-out configuration with erected folding tabs for the cover brake.

The invention is described below with reference to a preferred exemplary embodiment illustrated in the drawings. In these shows:

Fig. 10 shows a vertical section through the device along section line X - X in Fig. 4, and

Fig. 11 shows a vertical section through the device along section line XI - XI in Fig. 4.

The invention is explained below using a pack 10 of the hinge-lid type for cigarettes 11 .

The pack 10 has, as usual, a box part 12 for accommodating a group of cigarettes, which is wrapped in an inner wrapping 14 and has a closure tape 15, which can preferably be actuated several times, in the area of a removal opening.

The pack 10 also has a lid 16 pivotably mounted on the box part 12 and a collar 17, which is arranged on the inside of the box part 12 and protrudes from the box part 12, which is open at the top, in such a way that it rests against the inside of the lid 16 when the lid is closed.

The collar 17 has folding tabs 18 that serve as a cover brake. In the present case, two folding tabs 18 are provided as lid brakes, which are each arranged in the area of upright pack edges 19, namely pack edges 19 in the area of the transition from a large pack front side 20 of pack 10 to the respective pack narrow sides 21 of pack 10. In the present case, the package edges 19 are designed as rounded edges. Correspondingly, the collar 17 is provided with material weakenings in the region of the transition from a collar front wall 22 to collar side walls 23 , namely corrugations 24 parallel to one another, which run along an (upright) longitudinal axis of the pack 10 . It goes without saying that collars 17 without grooves 24 can also be processed, for example in the case of packs 10 without round edges and/or in the case of special shapes of collars 17.

The folding tabs 18 are formed as usual by punching in the material of the collar 18, namely by a C- or U-shaped punching in the area of the round edges or package edges 19.

1 shows that the folding tabs 18 are erected in relation to the areas of the collar 18 surrounding the folding tabs, so that when the lid 16 is closed they rest on the inside with a frictional and/or positive fit and hold the lid 16 in the closed position. Within the scope of this application, this is regarded as the task and function of a folding tab 18 for a cover brake.

4 shows a device for producing collars 17 for packs 10 for cigarettes 11. A continuous web of material 25 is preferably conveyed continuously along a horizontal transport plane 26 in the transport direction 27. It goes without saying that the transport plane 26 can also be arranged inclined or upright.

In the present case, the material web 25 is transported in the direction of a cutting device 28 by means of a pair of rotating advance rollers 29 on both sides of the material web 25, between which the material web 25 is transported. It goes without saying that the transport can also take place with other conventional means of transport.

In the cutting device 28, the web of material 25 is divided into individual blanks 30 for a collar 17 each. For this purpose, corresponding cutting knives are arranged on the circumference of a rotating cutting roller 31 of the cutting device 28 in a manner known per se. In the present case, the cutting roller 31 works together with a preferably smooth counter-roller 32 . Like the advance rollers 29, both rollers are arranged on both sides of the material web 25, so that the material web runs between the cutting roller 31 and the counter roller 32 and is thereby divided into individual blanks 30 by one or more cutting knives.

In addition, two C- or U-shaped punching cuts are made for the folding flaps 18 by punching knives preferably also arranged on the circumference of the cutting roller 31, so that following the cutting device 28 a blank 30 that has been completed to this extent is made available for a collar that is unfolded and is provided lying flat in the transport plane 26 and transported further in the transport direction 27 by a pair of transport rollers 50 .

Alternatively, it is of course also conceivable that the cutting device 28 is dispensed with and the blanks 30 for collars 17 prepared to this extent are provided elsewhere, for example as prefabricated blanks 30 which can be removed from a magazine and placed in the transport plane 26.

It is also conceivable that although the separating cuts for separating the collars 17 are made in the cutting device 28 , the material web 25 is already provided with the punchings for the folding tabs 18 in a prefabricated manner.

The next pair of rollers in the transport direction 27 belongs to a grooving device 33 which has a grooving roller 34 on one side of the transport plane 26 and a counter roller 35 on the other side of the transport plane 26 . Grooving roller 34 and counter-roller 35 have grooving projections 36 and corresponding depressions 37 on the circumference, which are designed for attaching the grooving 24 to the blanks 30 passed between the rollers.

A special feature is that the creasing device 33 also implements measures for raising the folding tabs 18 for the cover brake. Thus, two mandrels 38 are arranged on the circumference of the rotating creasing roller 34, which otherwise protrude beyond the circumference of the creasing roller 35. The feed of the blanks 30 is coordinated in such a way that a mandrel 38 erects a folding tab 18 in each case. Correspondingly, the counter-roller 34 has a recess 39 which offers space for an erected folding tab 18 . Through the mandrels 38, the folding tabs are Erecting pivoted about an axis which runs parallel to the direction of transport 27 .

It goes without saying that a number of recesses 39 corresponding to the number of folding tabs 18 to be erected can be provided. Alternatively, common recesses 39 for several folding tabs 18 can also be provided with a corresponding position of the erecting folding tabs 18 .

6 shows that the crescent-shaped mandrel 38 protrudes into the recess 39. In addition, the mandrel 38 has an inclined surface 40 which specifies the angle at which the folding tab 18 is erected. An angle of about 35° is preferred.

However, deviations are also conceivable, e.g. in a range from 25° to 45°. The angle is selected so that there is a partial fiber tear in the material of the blank 30, so that the folding tab 18 for the cover brake cannot swing back into the plane of the blank 30 due to the restoring forces of the blank 30 caused by the material.

It can also be seen that the folding tab 18 is pivoted about a bending edge 49 on which part of the counter-roller 35, in particular with a grooving projection 36, is supported. Alternatively, the counter-roller 35 can also be supported with an edge facing the recess 39 on the bending edge 49, for example if the counter-roller 35 is designed as a smooth roller without elevations and/or depressions.

The mandrel 38 is preferably designed as an exchangeable molded part.

A further special feature is that the creasing roller 34 and the counter-roller 35 also serve as accelerator rollers in order to space the blanks 30 severed from the material web 25 from one another. Correspondingly, the grooving roller 34 and the counter-roller 35 are driven faster than transport elements arranged upstream. As a result, a gap is created between the collars 17 and any unwanted residual connections that are still present are torn apart.

It is also conceivable that the creasing roller 34 and the counter-roller 35 are set up not to apply any creasing to the blank 30, for example as mentioned in FIG other pack shapes or with special collars 17. The creasing roller 34 and the counter-roller 35 are then merely accelerator rollers.

Finally, it is also conceivable that the acceleration function is also dispensed with, so that the creasing roller 34 and counter roller 35 then only serve as "normal" transport rollers of a pair of transport rollers.

In this respect, the terms transport roller or pair of transport rollers are used synonymously within the scope of this application for creasing roller, counter-roller, accelerator roller or creasing device.

7 and 8 show that the recess 39 is also adapted in the transport direction 27 to the dimensions of the folding tab 18 in this direction. The recess 39 has a front edge 40 directed transversely to the transport direction 27 and a rear edge 41 directed transversely to the transport direction 27, which are positioned adjacent to the corresponding sections of an incision for a folding tab 18 when the blanks 30 are transported by the creasing device 33 . In this way, tearing and/or further tearing of the surrounding blank can be prevented.

9 to 11 deal with the further transport of the blanks 30 with the folded flaps 18 erected:

After the creasing device, the blanks 30 pass through two collar switches as guide means. A first collar switch 42 has separate guide channels for the erected folded flaps 18 and the lateral areas of the blanks 30, namely a first pair of guide channels 43 for the folded flaps 18 and a second pair of guide channels 44 for the collar side walls 23.

It goes without saying that instead of the guide channels 43, 44, switches can also be used as guide means.

With the aid of the guide channels 44, the two collar side walls 23 are erected during the transport of the blanks 30 in the transport direction 27 and the folding tabs 18 are guided separately in the guide channels 43 (FIGS. 9 and 10). In this way it can be prevented that the folding tabs 18 return to the plane of the blank 30 are moved back and get caught there in the punchings. The collar side walls 23 are thereby raised by more than 90° and are thus bent over, so that the packaging material (cardboard) is preformed and in the pack 10 has only a slight tendency to bend back.

The blanks 30 are transported by transport belts 45 which rest on the top and bottom of the blanks 30 and move them in the transport direction 27 . The transport belts 45 are guided and driven over upper and lower pairs of transport rollers 46, respectively.

In a second collar switch 47 following the first collar switch 42, the collar side walls 23 are bent back in a similar manner so that the blank 30 can be transported in a flat state only with the folded flaps 18 erected. A further pair of transport rollers 48 is provided for this purpose following the second collar switch 47 (FIG. 11).

The blank 17 is then transferred to the so-called transverse push-off. The transverse pusher is a toothed belt that conveys the finished blanks 30 at right angles to the direction of transport 27 . The blanks 30 are then transferred to a stage where they are placed on the cigarette group 13 wrapped in the inner wrapper 14 .

In other words, the procedure is summarized as follows:

The material web 25 is continuously conveyed to the cutting device 28 . The web 25 is drawn in by the feed rollers 29 and moved to the cutting device 28 . The cutting device 28 makes perforation cuts, for example with a crushing blade, the U-shaped cut for the cover brake and finally the separating cut.

The blank 30 is then transferred to the creasing device 33 by transport rollers. The creasing roller 23 and the counter-roller 35 have a slightly higher speed than the rollers of the cutting device 28. As a result, a gap is created between the collars 17 and any unwanted residual connections that are still present are torn apart. In the creasing device, the blank 30 is creased by a wavy contour in the top and bottom rollers. The grooving serves to form the radius of the collar evenly. There is a crescent-shaped mandrel in the lower creasing roller, which actively pushes out the flat brake during the rotary movement. The upper backing roller touches the flat brake in the fold line and thereby defines the length. At the radii-shaped ends, the cover brake is also fixed by the top roller to prevent undefined folding (possibly tearing) of the material.

Then the blank is transferred to folding switches. The two side flaps are bent over at an angle greater than 90° so that the cardboard material is preformed and has little tendency to bend back in the pack. While the blank 30 slides through the folding switches, the cover brake is guided in a separate channel. This is to prevent the lid brake from getting caught in the plane of the box again and no longer folding out.

During further transport, the side flaps are bent back again so that the collar can be transported flat. The lid brakes remain unfolded (Fig. 11).
