  • the opposing element 34 is arranged in a fixed position along the wrapping path PI and therefore it is the drawer 20 which is arranged in front of the opposing element 34 moving along the wrapping path PI; alternatively, the opposing element 34 is movable and rests against the drawer 20 when the drawer 20 reaches the feeding station S2.
  • the drawer 20 moves along the wrapping path PI from the feeding station S2 to the feeding station S3, where a wrapping sheet 13 is folded in a "U"-shape" around the drawer 20 (whose pocket 24 contains the group 6 of cigarettes and the collar 9) ; in particular, the wrapping sheet 13 is folded in a "U"-shape” around the drawer 20 so that the "U"-folded sheet 13 closes the opening 26 of the pocket 24 and releases the opening 25 of the pocket 24.
  • the drawer 20 moves along the wrapping path PI from the feeding station S3 to the transfer station S4, in which a pusher enters the pocket 24 from the opening 25 to axially push out, of the pocket 24, the group 6 of cigarettes and the collar 9 coming out of the pocket 24 through the outlet opening 26 and dragging with them the wrapping sheet 13 folded in a "U"-shape.
  • the group 6 of cigarettes and the collar 9 are inserted into the "U"-folded wrapping sheet 13 when the group 6 of cigarettes and the collar 9 are extracted together from the pocket 24 of the drawer 20 through the opening 26.
  • the pocket 24 in each drawer 20 the pocket 24 has two grooves 35 which are axially arranged (i.e. parallel to the longitudinal development of the pocket 24), extending over the entire length of the pocket 24 from the opening 25 to the opening 26, are obtained through the side walls 28 and also cross the corresponding steps 32 (as is clearly illustrated in Figures 11 and 12), and are adapted to be crossed by lateral appendages of a rectangular-shaped pusher 36 (illustrated in broken lines in Figure 11) when the group 6 of cigarettes is extracted from the pocket 24 together with the collar 9.
  • the function of the two grooves 35 is to allow the rectangular-shaped pusher 36 (with its two lateral appendages) to push not only on the group 6 of cigarettes but to push also on the collar 9 so as to extract both of them from the pocket 24.
  • the pusher could push directly only on the group 6 of cigarettes (i.e. it could not push directly on the collar 9) and therefore the correct extraction of the collar 9 from the pocket 24 would not be guaranteed; instead, the two grooves 35 allow the lateral appendages of the pusher 36 to push directly also on the collar 9 thus ensuring the correct extraction of the collar 9 from the pocket 24.
  • the pocket 24 has (at least) one groove formed through the bottom wall 27 and also through the corresponding step 31 and said (at least one) groove is added to the grooves 35 formed in the side walls 28 or, alternatively, it replaces the grooves 35 formed in the side walls 28.
  • each pocket 24 has three steps 31 and 32 arranged in a "U"-shape; according to an alternative embodiment not illustrated, each pocket 24 could have only the step 31, only the two steps 32, or a further fourth step formed in the upper wall 29 (this embodiment is normally reserved for the case where the collar 9 has four walls) .
  • the collar 9 is initially inserted in each pocket 24, through the opening 26, which comes into contact by the head with the steps 31 and 32 (having a thickness at least equal, i.e. preferably slightly thicker, than the corresponding thickness of the collar 9) and then, subsequently, the group 6 of cigarettes is inserted through the opening 25 moving more on the inside of the steps 31 and 32.
  • the feeding of the collar 9 and of the group 6 of cigarettes is inverted and in this case the steps 31 and 32 have a thickness at least equal, or preferably slightly higher, than the corresponding thickness of the group 6 of cigarettes; in other words, according to this different embodiment, the group 6 of cigarettes is initially inserted in each pocket 24, through the opening 26, which comes into contact by the head with the steps 31 and 32 (having a thickness at least equal to, i.e. preferably slightly higher than, the corresponding thickness of the group 6 of cigarettes) and then, subsequently, the collar 9 is inserted through the opening 25 moving more on the inside of the steps 31 and 32.
  • the step 31 and/or the steps 32 could be movable to project inside the pocket 24 when the collar 9 and the group 6 of cigarettes are fed and to retract flush with the corresponding walls 27 and 28 when the collar 9 and the group 6 of cigarettes are extracted.
  • the collar 9 is preliminarily folded in a "U"-shape (as illustrated in Figure 6) and is then inserted folded in a "U"-shape into the pocket 24 of a drawer 20.
  • the collar 9 is not preliminarily folded in a "U”-shape and is therefore inserted flat (i.e. without folds) into the pocket 24 of a drawer 20; obviously, in this case the collar 9 is subsequently folded in a "U"-shape (as illustrated in Figure 6) after having been extracted from the pocket 24 of the drawer 20.
  • each collar 9 is axially inserted into the corresponding pocket 24 through the opening 26 which is opposite to the opening 25 through which the group 6 of cigarettes is axially inserted; i.e. each collar 9 is axially inserted into the corresponding pocket 24 through the opening 26, which is also used to axially extract the group 6 of cigarettes and the collar 9 from the drawer 20 together.
  • each collar 9 is pushed inside the drawer 20 and through the opening 26 until it (substantially) abuts against the step 31.
  • each collar 9 is axially inserted into the corresponding pocket 24 through the opening 25, which is also used to axially (and subsequently) insert the group 6 of cigarettes; in this embodiment, each collar 9 must be pushed inside the drawer 20 and through the opening 25 until it passes the step 31 (i.e. until it reaches beyond the step 31) .
  • Axially inserting each collar 9 into the corresponding pocket 24 through the opening 25 is possible, even if more complex, since an upper stroke must be imparted to the collar 9 and since the stroke of the collar 9 cannot be stopped against the step 31 which in this embodiment must be by-passed from above .
  • the packing machine 14 described above has numerous advantages.
  • the packing machine 14 described above is capable of operating rapidly (i.e. with a high hourly productivity) while ensuring, at the same time, a high and above all constant production quality.
  • This result is achieved thanks to the fact that the insertion of the collars 9 into the pockets 24 of the drawers 20 (at the feeding station SI) can be performed with high precision and without problem even when operating at high speed, since each collar 9 must enter in a very large space (the entire pocket 24) and therefore by entering into the pocket 24 it has wide tolerance margins which allow to compensate without any damage any positioning errors of the collar 9.
  • the packing machine 14 described above is particularly simple and inexpensive, since, in the pockets 24 of the drawers 20, the forming of the steps 31 and 32 only involves a trivial and fast mechanical machining of the components.
  • the embodiment illustrated in the attached figures refers to the manufacturing of a packet of cigarettes, but the present invention is applicable without substantial modifications also to the production of any other type of packet of smoking articles (for example a pack of cigars, a pack of electronic cigarettes of the liquid vaporization type, a new generation pack of cigarettes without tobacco combustion%) ⁇
