• a slider 87 which detects two inner packs 13 by a drive, not shown, and further transports a position.
• the slide 87 has on top two recesses 88 which are each sized to receive an inner pack 13.
• the guides 86 have a folding finger 90 in the inlet area, for folding over the other corner tabs 89 on both sides.
• the folding flaps 110, 11 1 are folded in the region of the inner side walls 35 during transport of the inner package 13.
• This can be done by folding switches, not shown, which is basically known from the prior art.
• Another peculiarity, however, is the sequence of folding.
• the folding flaps 110 projecting laterally in the region of the inner rear wall 34, which also have the fin fold 37 are folded against the package contents and then the folding flaps 11 projecting laterally in the area of the inner front wall 32.
• After transfer of the partially folded inner pack 13, this is in a configuration according to FIG. 4 on the cyclically driven sealing turret 92.
• the pockets 91 of the sealing revolver 92 rotating about a horizontal axis are directed radially and serve to receive an inner pack 13.
• a pocket 91 for receiving the inner pack 13 in extension of the conveyor 85 is in alignment therewith aligned.
• sealing devices 93 are provided, namely at eleven o'clock, twelve o'clock, one o'clock and two o'clock positions.
• the sealing devices 93 each consist of two sealing jaws 94 which can be pressed against the inner side walls 35 of the inner pack 13 over their entire surface from both sides.
• the sealing of the folding tabs 110, 111 takes place correspondingly in four successive stations. It is understood that both a larger and a smaller number of sealing devices 93 can be provided.
• the sealing devices 93 can also be arranged at other positions.
• the sealing turret 92 has two turret disks 95 arranged in parallel planes, which are arranged at a distance from one another.
• the revolver discs 95 recesses are arranged to form the radial pockets 91.
• an outer guide 96 along the transport path of the inner packs 13 on the circumference of the sealing turret 92 is provided.
• the sealing jaws 94 are moved for sealing in the horizontal direction against the inner side walls 35 and removed again after sealing for further transport of the sealing turret 92 by one position. The ejection of the fully sealed inner packs 13 takes place in the aforementioned extension station.
• the packs are detected by a horizontal discharge conveyor 97, which engages like the slider 87 between the turret discs 95 to remove a pack from a pocket 91.
• a horizontal discharge conveyor 97 On the discharge conveyor 97 are the inner packs 13 with the inner rear wall 34 pointing down on a conveyor belt 98 between drivers 99 thereof.
• coupons 100 or other print carrier can be placed on the inner front walls 32 of the sealing blocks 25.
• Coupon runners and magazines for holding the coupons 100 are known in the art.
• Fig. 5 shows this, the supply of a continuous material web 101 and an adjoining cutter 102 with knife roller 103 and counter roller 104 for separating the collar 16 from the material web 101.
• the isolated collar 16 are subsequently brought to a distance from each other and then passed to a cross conveyor 105 which transports the collar 16 in the direction of the conveyor 97 to above the sealing blocks 25. There they are placed by a collar 106 on the sealing blocks 25.
• the device can be designed in this area according to EP 0 496 261 B1 or EP 0 667 232 B1 from the applicant's own house.
• the sealing blocks 25 are transferred to a folding turret 107, in which prefolded blanks for the outer package 12 are kept ready.
• the package 10 is then completed on the folding turret 07 in a known manner.
