Definitions

  • the present invention finds advantageous application to the production of a rigid pack of cigarettes with a " twin" type hinged lid and containing two twin sealed wraps next to one another, to which the following disclosure will make explicit reference without thereby losing generality .
  • a pack of cigarettes commercially known as "twin” has been known for several years , it comprises a rigid outer container which houses two groups of identical cigarettes (namely, “twins” , hence the commercial name of this pack of cigarettes ) , which are arranged next to one another and are wrapped in corresponding wrapping sheets .
  • Figure 17 is a front view and with parts removed for clarity of a packing machine which produces the pack of cigarettes of Figure 1 and is made according to the present invention
  • Figure 21 is a schematic front view of three wrapping drums of the packing machine of Figure 17 ;

  • the closing label 17 is fixed to the cigarette sealed wrap 3 by means of a re- stick glue that does not dry, which is applied to the lower surface of the closing label 17 and is arranged all around the extraction opening 16 to allow the closing label 17 to be repeatedly partially separated from the sealed wrap 3 and then re- fixed to the sealed wrap 3 .
  • the sealed wrap 3 is devoid of the extraction opening 16 and of the respective closing label 17 and has a removable upper portion, which is separated from the rest of the sealed wrap 3 by a preweakened tearable line to be removed by tearing at the first opening of the sealed wrap ; in this embodiment , the sealed wrap 3 is preferably provided with a tearable opening strip to facilitate the breaking of the sealed wrap 3 along the preweakened line .
  • the end 25 is parallel to a first larger side wall of the group 14 o f cigarettes and protrudes from the first lower wall of the group 14 of cigarettes continuing beyond the larger side wall ; similarly, the end 26 is parallel to a second larger side wall of the group 14 of cigarettes and protrudes from the lower wall of the group 14 of cigarettes continuing beyond the second larger side wall .

  • the two ends 25 and 26 have the same length, they are both folded into an "L" shape against the lower wall of the group 14 of cigarettes to form the sealing fin 27 , and finally the sealing fin 27 (which is initially in the centre of the bottom wall of the group 14 of cigarettes ) is folded by 90 ° against the bottom wall of the group 14 of cigarettes .
  • the two open side edges of the wrapping sheet 18 (which has a tubular shape around the group 14 of cigarettes ) are closed by means of the so-called " soap-bar fold" that for each side edge provides for : folding two smaller wings 28 and 29 against the smaller side wall of the group 14 of cigarettes ( in fact , the smaller wing 28 arranged at the top wall of the group 14 of cigarettes is folded previously when the wrapping sheet 18 is first in contact with the group 14 of cigarettes and folds in a "U"-shape around the group 14 of cigarettes ) , folding a larger wing 30 against the smaller side wall of the group 14 of cigarettes and over the two previously folded smaller wings 28 and 29 , and finally folding the other larger wing 31 against the smaller side wall of the group 14 of cigarettes and over the two smaller wings 28 and 29 and the larger wing 30 previously folded .
  • these side folds are stabili zed by heat sealing, namely, by heat sealing the overlapping parts of the wrapping sheet 18 at the smaller side walls of the group 14 of cigarettes .
  • the packing machine 33 comprises a forming unit A in which the groups 14 of cigarettes are formed in succession, a wrapping unit B in which a respective wrapping sheet 18 is wrapped around each group 14 of cigarettes to form a sealed wrap 3 , and a wrapping unit C in which a blank 32 is wrapped around each pair of coupled sealed wraps 3 (namely, arranged next to one another ) to form an outer container 2 provided with a lid 4 .
  • the wrapping unit B comprises a wrapping conveyor 38 which is arranged downstream of the forming conveyor 37 (namely, it receives the pairs of groups 14 of cigarettes next to one another from the forming conveyor 37 in the trans fer station S2 ) and is designed to move the pairs of groups 14 of cigarettes next to one another together with the corresponding wrapping sheets 18 along a wrapping path P2 to ( start to ) fold each wrapping sheet 18 around the corresponding group 14 of cigarettes .
  • each wrapping sheet 18 is initially folded in a "U"-shape and subsequently into a tube around a corresponding group 14 of cigarettes and the tubular wrap (having two open side ends ) thus formed is stabili zed by transverse sealing ( as illustrated in Figures 9- 15 ) .
  • the wrapping drum 46 by rotating around the rotation axis 47 moves each pair of pockets 48 next to one another along the circular wrapping path P2 between the trans fer station S7 in which the pair of pockets 48 next to one another receives a pair of groups 14 of cigarettes next to one another and coupled to the wrapping sheets 18 by the wrapping drum 43 and the trans fer station S4 in which the pair of pockets 48 next to one another releases the pair of groups 14 of cigarettes next to one another and coupled to the wrapping sheets 18 to the wrapping drum 40 .
