Abstract: A packaging machine to make an airtight wrapper (12) comprising a wrapping sheet (112) wrapped airtight around a structured assembly (11) consisting of an organized group of smoking articles (14) associated with a reinforcement insert (16) comprises, in working sequence on one or more cyclical conveyor devices (39, 71) of the wheel or carousel type: a structured assembly formation unit (30), a combination unit (31) suitable to combine the structured assembly (11) with said wrapping sheet (112), a wrapping sheet work unit (32) and a welding unit (34).

Abstract: Method to feed and form organized groups of smoking articles, providing to feed a plurality of pockets of a transfer conveyor with pockets moved step-wise, thrusting said organized groups of smoking articles, by means of thrusters actuated independently from each other, in a direction of transfer and through respective forming drawers, into said pockets on the basis of a predefined production rhythm. The method provides, in the event of obstruction, stoppage or blockage of a forming drawer, to vary the operating speed of the thrusters associated with the other forming drawers in coordination and in synchrony with the step-wise feed speed of said transfer conveyor with pockets, in order to obtain an effective production rhythm equal or near to said predefined production rhythm.

Abstract: Transfer device configured to transfer smoking articles in a direction of transfer from a feed store to a transfer conveyor with pockets of an apparatus to feed and form organized groups of smoking articles. The transfer device includes a forming drawer comprising an upper wall and a bottom wall. The upper wall is disposed fixed in a position opposite the bottom wall and the bottom wall is configured automatically mobile with respect to the fixed upper wall between a closed position and an open position.

Abstract: Packet for smoking articles, comprising an external shell and an internal shell to contain smoking articles. The external shell comprises an external containing body, a closing lid hinged to the internal shell and a connection tongue configured to connect the closing lid to the external containing body. Moreover, the internal shell is configured to slide, with respect to the external containing body, between a closed configuration where the internal shell is completely inserted inside the external shell, and an open and extracted configuration where the internal shell is partly extracted from the external containing body.

Abstract: A packet is suitable to contain products in loose or organized form and comprises at least two elements such as a mobile lid, affecting the upper part of the packet, and a containing body. The containing body consists of two lateral, a rear wall, a front wall, an upper wall and a lower wall, all defining a front bulk and a lateral bulk. The elements are connected to each other by movement means. The mobile lid is suitable to assume a closed position and an open position. The mobile lid, the walls of the containing body and the movement means define a kinematic mechanism suitable to make the mobile lid assume an open position as well.

Abstract: Method to command and control an electric motor of an automation unit. The unit comprises a mechanical member, driven by a drive shaft, a central command and control unit, and a position detection mean. The method provides that the central command and control unit receives the position signals of the shaft of the electric motor and/or of the mechanical member from the position detection mean, divides the operating cycle into a plurality of sub-phases equal with respect to each other, consisting of elementary units and, for each of said sub-phases, or multiple of sub-phases, selects predefined or self-learnt current reference values, and generates a signal consisting of an instantaneous current reference (feed forward) for the electric motor.
