The slot nozzle 24 for applying the glue surfaces is for the Preparation of the blank according to FIG. 2 with an additional one Nozzle slot provided for applying the two front glue surfaces 67, 68.

All glue surfaces of the blanks according to FIG. 1 and FIG. 2 are expediently arranged on the same side, on the outer or printed or coated side of the blanks. This has the consequence that with certain folding flaps or connecting flaps the glue surfaces are not immediately moistened or are supplied with water, but the corresponding, folding flaps to be connected.

Alternatively, the glue surfaces can also be in accordance with the feed of moisture or water on different sides of the blank or the material web. Therefor then another glue unit is required.

Serves for the production of packs 10 of the type described a manufacturing system according to FIG. 4. This consists of a Packaging machine 41 and a separate material unit 42. The latter is positioned on the back of the packaging machine 41 and expediently in accordance with DE 198 04 614.6 educated. The material unit 42 contains bobbin magazines for the web-shaped packaging material to be processed. It it is on the one hand tinfoil 43 and on the other around paper bobbins 44. Furthermore, banderole bobbins 45 ready.

The bobbins 43, 44, 45 are each on a working pin 46, 47, 48 rotatably mounted so that the material webs are drawn off can be. These are fed to the packaging machine 41. In the present case, the material web is of particular interest 22 for the production of the (outer) blanks 12 from paper.

That of the respective paper reel 44 on the working spigot 47 removed material web 22 passes through a splice unit 49, which has the task of a running material web 22 with a new material web to a reel to be connected connect. The material web 22 then passes through a web store 50 to compensate for movement differences. It follows the described glue unit 23, which here in the area of Material unit 42 is arranged.

A drying unit 60 follows the glue unit 23 intended. This is in the area in the present example the packaging machine 41 is formed (FIG. 5). The drying unit 60 is with one for quick drying of the glue surfaces suitable energy source, for example with an infrared dryer. In the present embodiment are two heating rods within an insulating housing 72 73 installed immediately above the material web 22. The heating rods 73 are surrounded by an arcuate reflector 74.

The one provided with glue or glue surfaces in the manner described Material web 22 is after the glue surfaces have dried fed to a folding unit, namely one in an upright plane continuously rotating folding turret 51. These are along the Circumferentially spaced units for feeding the material web 22 and for severing the blanks 11 and 12 assigned. Otherwise, the folding turret 51 according to US 4,852,335.

In the area of a paper station 53 (FIG. 7) of the folding turret 51, the material web 22 made of paper or the like is fed. The paper station 53 has a separating unit 54 for Separating the (outer) blanks 12 from the material web 22.

For the manufacture of packs 10 of the soft cup type Folding turret 51 with a plurality of along the circumference Provide spaced material receptacles namely so-called folding mandrels 55. These are elongated hollow bodies that are open at both ends and the dimensions correspond to the internal dimensions of the package 10. The blanks, namely inner blank 11 and outer blank 12, are on the outside of the thin-walled hollow mandrels 55 folded. The package contents, namely a cigarette group, is inserted lengthways through a plunger into the folding mandrel 55 introduced. To form the filled package 10 the cigarettes are expelled through the pestle, taking the partially folded blanks 11, 12.

As can be seen from Fig. 8, in the area of the paper station 53 the outer cuts 12 in the correct position on the folding mandrel 55 or applied to the inner blank 11. Strip a material to form folding flaps of the bottom wall 17 protrudes in the starting position on the free side with a revolver disc 57 connected folding mandrels 55 away. The excess material serves among other things, to form the radially outer and inner Longitudinal flaps 20, 21. These folding flaps of the bottom wall 17 are successively by fixed folding switches 61, 62 folded due to the relative movement of the folding mandrels 55.

Before the bottom wall 17 is folded, the side tabs 18, 19 folded, the one in the direction of movement of the folding mandrels 55 rear side are formed as a supernatant. The radial external, in the finished packs 10 internal side flaps 19, which has the side glue surfaces 27, is first by a folding organ against the rear side of the folding mandrel 55 folded. For this purpose, a folding bike 63 with protruding Faltstegen 64. After that or in a superimposed movement the radially inner side flap on the outside of the pack 18 folded by a separate, movable folding member. Here it is an angular moth 65, the with a right-angled folding leg 66 den Side tabs 18 detected and against the approximately radially directed Side wall 16 of the package 10 or the folding mandrel 55 is folded over. The folder 65 assigned to each folding mandrel 55 is to this Purpose pivoted.

Before or during the folding steps described above the glue surfaces by adding solvent or water activated. The side glue surfaces attached to the side tab 19 27 are immediately moistened with water. To this The purpose is fixed in the area of the paper station 53 a nozzle unit 75 positioned. This exists in the present Trap of several arranged side by side in the axial direction Nozzles 76. A nozzle 76 is assigned to each side glue surface 27. Through the nozzle assembly 75 or the nozzles 76 at the moment the comparison with the pack 10 or with the side tab 19 dispensed a dosed portion of water immediately transferred to the associated side glue surface 27 becomes. This activates these glue areas. The folding organ, namely the folding webs 64 are designed so that they the side tab 19 with the activated side glue surfaces 27 in the area between these side glue surfaces 27.

Then, or in a superimposed movement, the radially inner outer side tabs 18 by a separate, movable Folded organ folded. It is an angular one trained moth 65, the one with a right angle protruding folding leg 66 grips the side tab 18 and against the approximately radially directed side surface of the pack 10 or the folding mandrel 55 or the folding mandrel 55. Everyone Folding mandrel 55 associated folder 65 is pivotable for this purpose stored.

Also glue surfaces for connecting folding tabs of the bottom wall 17 must be activated with solvents, especially water. For this purpose, the folding organs for the Side tabs 18, 19 a further nozzle assembly 77 stationary next to the movement path of the packs 10 and the folding mandrels 55 positioned. The nozzle assembly 77 is expedient only from a single nozzle that is used to activate the elongated Floor glue surface 28 with a longer opening cycle a corresponding nozzle 78 is controlled. A special feature is that the solvent / water on the outside Langslappen 20 of the bottom wall 17 is applied while the inner longitudinal tab 21 (on the outside of the blank) the ßoden-glue surface 28 carries. Accordingly, here indirect moistening of a glue surface instead. The one in the radial direction pointing inner longitudinal tab 20 is on its inside - from above or in the radial direction - with water moistened and then by the folding switch 62 due to the relative movement erected up to the plant on the previously folded Longitudinal lobe 21. Through the moistened longitudinal lobe 20 the floor glue surface 28 activated and so the connection is made.

Following this folding station for the bottom wall 17 follows stationary pressure element, namely a pressure roller 71, which the connection the folding tab of the bottom wall 17 is stabilized by pressure.

Correspondingly, the band 31 of the pack 10 fed and by activating the band glue surfaces 29, 30 connected to the pack 10. For this purpose there is a banderole station 79 provided. This is in the area a so-called dry turret (not shown), which is made of a number of elongated tubular supports for the packs 10 consists. On the inlet side of the drying tubes the banderole 31 is transferred to the associated package 10. Structure and mode of operation of the dry turret and the Banderole transfer result from US 5 544 467.

A banderole apparatus 80 is part of the banderole station 79. This is expediently modeled on DE 196 47 670.4 built, unless deviations below be described. Banderoles 31 are through the banderolen apparatus 80 in the radial direction of the packs 10 or End wall 56 supplied. The banderole apparatus is for this purpose 80 equipped with a conveyor for the banderoles 31, with a suction belt 81. The elongated, rectangular banderoles 31.

Glue surfaces, namely banderole glue surfaces 29, 30 for gluing the banderoles with front wall 13 and rear wall 14 are on the outer panel 12 attached. To activate the banderole glue surfaces 29, 30 becomes a corresponding area of the banderoles 31 moistened. In the area of the suction belt 81 is a nozzle assembly 82 positioned. This transmits in the horizontal direction Portions or drops of the solvent, in particular of water, on the free side of the banderoles 31. This is applied to the packs 10. In the present example the nozzle assembly 82 consists of two side by side Nozzles 83. These each transmit one at the same time Drops of water 84 on the banderoles 31. There are therefore two Water drops 84 in each case at an edge region of the band 31 next to each other, matching the positioning of the banderole glue surfaces 29, 30. These are therefore also indirectly moistened, namely by moistening the surfaces to be attached.

The band 31 is connected to the pack 10 - Analogous to US 5 544 467 - when inserting the packs in one Drying tube with U-shaped folding of the sleeve 31.

The described process of manufacturing packs with Glue connections from (water) soluble glue can also be used with others Pack types are used, each with the glue applied outside the area of the packaging machine becomes. This can also be done at the factory during the manufacture of the packaging material be attached, and also by others Process of the order, such as offset, gravure and other printing processes.
