Abstract: A method and device for finishing packets having respective overwrappings of heat-shrink material, whereby the overwrappings are sealed about the respective packets and then heated to shrink and adapt to the configuration of the packets; after being heated, the overwrappings are cooled to set and so reduce the risk of damage to the overwrappings at subsequent processing stages.

Abstract: A wrapper with a hinged lid for tobacco products presents a front face (7), a rear race (8), two flank faces (9), a top end face (10) and a bottom end face (11), and comprises a container (13), a lid (15) hinged to the container along a crease lid (16), and a reinforcing frame (25). The wrapper (1) is fashioned from a flat diecut blank (37) comprising a central panel (41), two lateral panels (42) flanking the central panel (41) and an end panel (43), all aligned along a first axis (38), also an appendage (45) aligned with the central panel (41) along a second axis (39) perpendicular to the first axis (38), connected to one end of the central panel (41) and destined lo provide the lid (15). The frame (25) is incorporated directly into the blank (37), created by a process of deformation that involves selectively embossing portions (17a, 19a) of the front (17) and the flanks (19) of the container (13).

Abstract: A method and device for transferring packets, whereby two parallel, superimposed rows of packets are fed in a horizontal direction to a first transfer station, and the lead packets in the two rows are then conveyed in a vertical direction from the first transfer station to a second transfer station, where the lead packets are parted in the vertical direction; at this point, the parted lead packets are transferred in the horizontal direction to a heat-shrink unit having two parallel, superimposed, substantially horizontal channels, each of which is engaged by a respective row of packets.

Abstract: Transparent outer wrappers for cigarette packets are prepared by advancing a continuous strip of overwrap material along a given feed path in a given direction, piercing a predetermined area of the strip with a series of slits spaced apart one from another and extending nominally transverse to the feed direction, and bonding a narrow ribbon to the strip along the predetermined area, aligned on at least one portion of the slits; the strip then passes under a blade shaped so as to cut a series of “U” notches spaced apart one from the next, each creating a pull tab at the end of the ribbon, before being divided ultimately into leaves by a pair of contrarotating cutter rollers equipped with respective blades. Each single leaf serves as a wrapper for a relative pack, fashioned so that when torn open by pulling the ribbon, the ribbon encounters the slit and initiates two break lines extending away from the ribbon on either side to facilitate the removal of the wrapper in its entirety.

Abstract: An overwrapping machine for packets of cigarettes, wherein a first feed line feeds the packets of cigarettes successively along a first path, and a second feed line feeds sheets of transparent packing material successively along a second path intersecting the first path at a cross station to pair each packet with a respective sheet of packing material; and wherein a guide for the packets is located upstream from the cross station, and has an output end, for the packets, facing the cross station; the guide is movable to and from a forward operating position, in which the guide forms part of the first path, and the output end of the guide is positioned substantially contacting the second path.

Abstract: A method and device for finishing cellophane-wrapped packets, whereby a succession of stacks, each defined by two superimposed packets having respective heat-shrink overwrappings, are fed successively by a conveyor wheel along a circular track extending through an unloading station, prior to reaching which the packets in each stack are parted in an axial direction with respect to the conveyor wheel, and are then fed, in a radial direction with respect to the conveyor wheel, along respective superimposed paths separated by a heating plate.

Abstract: Packets (2) of cigarettes are packed in multiples adopting a rigid carton (1) of parallelepiped shape presenting two end faces (11, 12) coinciding with the flanks (13, 14), and four side faces (3, 4, 5, 6) of which two coincide with the bottom (10) and the top (8).

Abstract: A method and machine for transferring packets, whereby, as a continuous line of packets is fed in a first direction, the first packet in the line is transferred in a second direction perpendicular to the first direction, while the line and the first packet continue travelling in the first direction; the first packet is subsequently conveyed in the second direction along an output path.

Abstract: A rigid cigarette packet (1), in the form of a right parallelepiped and extending along an axis (Z), has a container (4), and a lid (5) hinged to the container (4) along a hinge (6) so as to move between a closed position and an open position in which the lid (5) permits access to a compartment (14), housing cigarettes (2), through an opening (15) in the container (4), which has a front wall (9), a rear wall (10), two lateral walls (11), a bottom wall (12), and a top wall (13); the opening (15) extends along the front wall (9), between the hinge (6) on the front wall (9) and a free edge (18) of the front wall (9).
