A cigarette feeder 100 becomes cigarettes to a cigarette block forming device 101. In the cigarette block forming device 101, in known forms of cigarette blocks, for example Blocks of 19 or 20 cigarettes. It can be filter cigarettes or cigarettes act without a filter. The cigarette packs formed are transferred into a cell band 102 and from there into a block handover 104 continues. Next up an inside wrap, such as tinfoil, fed to the packing machine and around the cigarette blocks beaten. The block transfer is with the reference number 104 indicated and the inside wrap feed with the Reference number 105. Blocks in continue Inner wrap 106 shown. As a next step the blocks in inside wrap 106 are already with prefolded collar in a collar feeder 107 at one first folding plate 108 merged and folded.

When transferring from a first folding plate to one second folding plates 109 are blankets 110, some of which are glued, in particular in such a way that the collar with the blankets and an area of the Inside wrap to be glued to the blank can, the one with collar and inside fold Blocks fed. Then in the second folding plate the respective blank 110 up to the side tabs folded. The blank feed is designated 111. After the second folding plate 109, the side tabs the blank with a strip of hot glue and one Strips of cold glue in the gluing area for side tabs 112 and fed to a molding wheel 113, in where the final folding takes place. After a certain time the packs remain in the form wheel are due to the hot glue cooling adequately fixed so that the glued parts of the Packs can no longer move against each other. Finally, the packs are made dry lines 114 fed. Within the scope of this invention means glue especially hot and cold glue.

It is then possible in further procedural steps for example, to wrap a film and / or pack cigarette sticks.

The packing machine is divided into different areas. These are the area of block formation A, inside wrap B, the area of the folding plate C and the area the gluing of the side flaps of the blanks and the eventual folding D.

In normal operation, the packing machine is completely through the main drive 103 driven, via a Drive distribution for areas A and B 120 and an associated toothed belt 115, via the drives first folding plate 121 and second folding plate 122 and about the drive separation for blank feed 123 and that Superposition gear for gluing and form wheel 124 and the associated toothed belts 115.

If a fault occurs, the machine stops inside fewer cycles, e.g. two to three bars, and remains stand completely in the prior art, so that Packs with already glued side tabs or with Adhesive side tabs without corresponding to be folded, dry so that they already glued packs are not properly manufactured can and become a committee. Even partially glued blankets 110 must then, since they Have already passed the gluing line, excluded become. However, in the prior art when commissioning the packaging machine, there are also others Packs committee, namely those who are in the Folding plates are and those not freshly glued Blanket can be fed.

According to the present invention, the committee however reduced. This is achieved in that in this particular embodiment in the stopping phase the main drive 103 has at least one auxiliary drive, such as the second auxiliary drive 126, is put into operation and via a superposition gear for gluing and form wheel 124, that in particular is a differential gear, the packaging machine in the gluing area is driven empty for side tabs 112. The Auxiliary drive can be operated until that too Form wheel is empty.

Before starting up the main drive 103 by means of the first auxiliary drive 125 and a drive disconnection for the blank feed 123, for example is a differential gear, blankets freshly glued and the blank feed for further Operations are filled to operate at one set main drive 103 sufficiently freshly glued Blankets for further blocks to be packed in the inner wrapping to provide.

2 is a diagram of the speeds of the main drive and an auxiliary drive shown. On the The speed is plotted on the ordinate and on the Abscissa time. The main drive has a speed 200 and one of the auxiliary drives or both or have a speed 201. It can be spotted, that the speed of the main drive 200 from a certain Time will decrease while stopping the speed of the auxiliary drive 201 increases. Out of this results in a total speed 202 which is a sum of Speed 200 and speed 201 is. With this sum the range of speeds 202 is driven.

When restarting the main drive first started an auxiliary drive and at actual commissioning of the main drive then the auxiliary drive stopped. Here it is particular possible to drive from auxiliary drive to Switch main drive or the drive separation of the Separate auxiliary drive from the corresponding area.

This embodiment has made it clear that Committee through the inventive method and device according to the invention can be reduced. It it has also become clear that further drive separations or provided in the special case differential gear can be, such as on the drive for the second folding plate 122 or when driving the first Folding plates 121 to prevent further rejects if necessary.
