  • the applicator unit which applies the transverse closure strip 47 is essentially similar to that described earlier. There being no unit feeding in packs of blanks 30, the two reels 48, 48' are in this case horizontally adjacent to each other.
  • the applicator disc 54 of the transverse closure strip applicator unit is positioned eccentrically with respect to the axis of the transfer disc 24', over the top of the finished packet 20, the latter having been rotated through 90° with respect to the position in which it was taken from the folding drum 14' and is displaced to one side of said transfer disc 24'.
  • the transfer disc 24' rotates the finished packet 20 from the position in which the cigarette axes lie in the front-to-rear direction of the machine to the standing position where their axes are oriented vertically, the top of the packet being towards the slot 154 of the applicator disc 54.
  • the packet 20 is pushed out of the socket 124' into a coinciding position underneath the slot 154 of the applicator disc 54 and is then pushed in the direction of the arrow 61 through said slot 154, thereby causing the transverse strip to be applied to the top of the packet as described in the previous embodiment, and simultaneously moving the packet 20 to the inlet of the magazine in which the discharged packets are stored.
  • the storage magazine has only one transport track 18, but it can also be built in a similar way to the illustrative embodiment described earlier.
  • Figs. 18A and 18B illustrate the soft-packet version of the cigarette packaging machine denoted 1S in Fig. 12, produced by combining blocks 101 and 301.
  • Figs. 16A and 16B illustrate the block 201 which, coupled to the previously described block 101, provides the hard-packet version of the cigarette packaging machine 1H.
  • This block 201 comprises the forming unit which forms the hard packet around the foil-wrapped group of cigarettes, the feeder of blanks 130 from packs of blanks 30, the magazine 29 of blanks on the rear side of the machine, the feeder of the web of material, the unit 35, 34 which cuts and applies the collar 31 from said web of material and the magazine for storing discharged packets.
  • the hard packet forming unit has only two socketed drums 14' and 15' which are positioned vertically one above the other and rotate about axes parallel with the front-to-rear direction of the machine.
  • the applicator disc 34 by which the collar 31 is applied cooperates directly with the drum 14' which feeds the foil-wrapped groups of cigarettes to the drum 15' above it which folds the blank 130 for the hard packet.
  • the transfer from the foil sheet folding drum 6 to the drum 14' is brought about by a transfer disc 11' which rotates about a vertical axis and has peripheral sockets arranged in diametrically opposing pairs, e.g.
  • a further point of difference with the previous illustrative embodiment is that instead of the transfer discs 23 and 24 for transferring the finished packet 20 from the blank 130 folding drum to the magazine where the discharged packets are stored, a spoked wheel 21' is provided, similar to that used to transfer finished packets 20 from the lower track 18 to the upper track 19 of the storage magazine.
  • the spoked wheel 21' is so arranged that the finished packets 20 are transferred to it by a radial movement of expulsion from the drum 15', whereby the packet 20 is brought into axial coincidence with the socket 121 of the wheel 21' and then by an axial movement in the direction of the arrow 62.
  • Figs. 19A and 19B which illustrate the complete packaging machine 1H produced by combining blocks 101 and 201
  • the drums 14' and 15' of the hard packet forming unit and the transfer disc 11' are so positioned that said drums are in line with the drums 5 and 6 of the foil wrapping forming unit, while the transfer disc 11' extends underneath the folding drum 6 to a position where one of its peripheral sockets is vertically in line with the bottommost vertical socket of the folding drum 6.
  • the group of cigarettes in their foil wrapping is therefore transferred to the transfer disc 11' by radial expulsion from the folding drum 6.
  • the foil-wrapped group of cigarettes is transferred from the disc 11' to the drum 14' by a vertical upward movement followed by a radial movement towards the drum 14', the corresponding socket thereof being in alignment but vertically displaced upwards relative to the adjacent socket of the transfer disc 11'.
  • all the working parts of the machine are arranged in a vertical front space of the machine and the path of the products being packaged and of the packaging materials also lies within this space.
  • the width measured in the front-to-rear direction of the machine is such as to permit both direct visual monitoring of all packaging stages and of the working parts, and direct access by the operator to the products in the different stages of packaging and to the working components of the machine. In particular, this width is between approximately two and three times the axial length of the cigarettes.
  • the packaging machine according to the invention may be constructed in a non-convertible version, i.e. for packaging cigarettes in either hard packets only or soft packets only; and all without departing from the underlying principle described above and claimed below.
