Abstract: A method of folding a sheet of packing material, having an extraction opening, about a group of cigarettes; the method includes the steps of: bringing a first end wall of the group of cigarettes into contact with the flat sheet of packing material, so that the major transverse edges of the group of cigarettes are parallel to the short sides of the sheet of packing material, and the minor transverse edges of the group of cigarettes are parallel to the long sides of the sheet of packing material; folding the sheet of packing material into a U about the major transverse edges of the first end wall, so that the sheet of packing material covers both the major lateral walls of the group of cigarettes completely; folding the sheet of packing material onto a second end wall of the group of cigarettes; and folding the sheet of packing material onto the minor lateral walls of the group of cigarettes; the first end wall of the group of cigarettes is positioned asymmetrically with respect to the sheet of packing material

Abstract: A package of cigarettes having a group (4) of cigarettes; an inner package (3) which encloses the group (4) of cigarettes, is defined by a sheet (22) of transparent, heat-seal plastic packing material folded directly about the group (4) of cigarettes and in direct contact with the cigarettes, and is stabilized by heat sealing; and a U-shaped stiffener (23) of rigid material located inside the inner package (3) and contacting the group (4) of cigarettes.

Abstract: A machine for packing cigarettes, having a group-forming device for forming a group of cigarettes, and a conveyor for feeding the group along a given path; the group-forming device has a number of seats, each for housing a respective subgroup of cigarettes; the subgroups are pushed, in use, through respective insertion channels tapering towards the conveyor, into a pocket of the conveyor to define the group of cigarettes; and the pocket has a substantially triangular cross section parallel to the path.

Abstract: On a packing machine, packets of cigarettes, selected from different alternative packets of cigarettes of at least a first and second type, are produced by transferring groups of cigarettes relative to the selected type of packet from a forming path to a first packing path, along which an inner sheet of packing material is folded about each group of cigarettes, and then to a second packing path, along which at least a collar is folded about each group of cigarettes and on top of the inner sheet of packing material; each group of cigarettes is then transfer red, depending on the type of packet selected, to a third packing path, along which folding of a first outer blank about each group of cigarettes is completed to form a packet of cigarettes of the first type, or to a fourth packing path, along which folding of a second outer blank about each group of cigarettes is completed to form a packet of cigarettes of the second type.

Abstract: A packet filled with articles of elongated shape comprises a substantially parallelepiped outer wrapper presenting a front wall, a rear wall or back, two flank walls, a top and a base, and scored or punched with a cutout delimiting a closure flap; the cutout appears as transverse line occupying a central area of the front wall, and two lines extending from the ends of the transverse line, at a predetermined distance from the corner edges of the relative flank walls, along the front wall and at least across the width of the top. The area of the wrapper occupied by the cutout is covered by an adhesive label furnished with a pull tab. The packet comprises an inner element serving to fill two longitudinal and substantially parallelepiped spaces within the wrapper, each coinciding positionally and dimensionally at one end with a relative portion of the top lying outside the line of the cutout.

Abstract: A method of folding a sheet (2) of packing material about a group (3) of cigarettes; the method includes the steps of: bringing a first end wall (8a) of the group (3) of cigarettes into contact with the flat sheet (2) of packing material, so that the major transverse edges (10) of the group (3) of cigarettes are parallel to the long sides of the sheet (2) of packing material; folding the sheet (2) of packing material into a U about the major transverse edges (10) of the first end wall (8a), so that the sheet (2) of packing material partly covers both the major lateral walls (6) of the group (3) of cigarettes; folding the sheet (2) of packing material about the minor transverse edges (10) of the first end wall (8a), so that the sheet (2) of packing material completely covers both the major lateral walls (6) and the minor lateral walls (7), and forms a tubular package having one open end at a second end wall (8b); and folding the sheet (2) of packing material onto the second end wall (8b) to complete the foldin

Abstract: A rigid hinge-lid packet (1) of prismatic shape, appearing substantially-triangular in section, comprises a container (10) surmounted by a lid (12), attached to the container (10) by way of a hinge (19) and pivotable between a position in which the packet is open and a position in which the packet is closed. The lid (12) of the packet (1) is retained in the closed position by locking elements (27) fashioned as a tongue (29), associated with one of the container (10) or lid (12), and a notch (30) formed in the other one of the container (10) or lid (12), insertable positively one into the other.

Abstract: A method and wrapping unit for producing a package containing a group of cigarettes, and which include: feeding the group of cigarettes along a path; feeding a sheet of wrapping perpendicularly to the path of the group of cigarettes; feeding a tubular spindle along the path of the group of cigarettes to intercept the sheet of wrapping and fold the sheet of wrapping into a U about the tubular spindle; and feeding the group of cigarettes through the tubular spindle to slide the sheet of wrapping off the tubular spindle and apply the U-folded sheet of wrapping to the group of cigarettes.

Abstract: A method and packing machine for combining an insert and a group of cigarettes; the group of cigarettes is fed to a first seat of a pocket, which first seat is designed to house the group of cigarettes; the insert is fed to a second seat of the pocket, which second seat is designed to house the insert and is separate from the first seat; and the group of cigarettes and the insert are expelled together from the pocket by a common ejector device, so as to combine the insert with the group of cigarettes.

Abstract: In a cigarette packer, groups of single cigarettes are first assembled by a formation unit and placed in trays carried by a conveyor, then directed in succession along a set feed path, advancing sideways-on, toward a wrapping unit by which each one is enveloped in a transparent or at least partly transparent wrapper; during the transfer from the formation unit to the wrapping unit, the trays are directed past a print unit stationed along the feed path, by which at least one graphic element such as lettering or a logo is impressed on at least one cigarette making up each group.

Abstract: Packets of cigarettes appearing prismatic in shape with a triangular cross section are ordered side by side and in direct contact one with another to form a group alignable on a predominating longitudinal axis, with the axes of the single packets transverse to the direction of alignment. The assembled group of packets is prismatic in shape, with a longitudinal section of trapezoidal appearance, and wrapped in a rigid carton aligned likewise on the predominating longitudinal axis, similarly prismatic and presenting a longitudinal profile of isosceles trapezoidal outline.
