摘要:
A packet (2) of cigarettes and relative production method, wherein a label (7), defined at least partly by a portion (8) of magnetic tape, is applied to a component (3a, 16, 20) of the packet (2) so as to be visible on the outside of the finished packet (2); the label (7) being printed, on the machine and by means of a printing device (34), with data relating to the packet (2).
摘要:
A rigid container for tobacco products is prismatic in shape, substantially rectangular or triangular in section, and presents a plurality of side faces each presenting a flat central portion and two longitudinally oriented lateral bands of curved profile of which the concave surface is directed toward the inside of the container; the contiguous lateral bands of each two adjacent side faces are joined one to the other along a sharp longitudinal corner edge.
摘要:
A packet serving to contain a group of cigarettes appears substantially parallelepiped in shape with a predominating longitudinal axis disposed parallel to the longitudinal axes of the cigarettes, and comprises a front, a back and two flanks, also a bottom, and a top that can be opened at least in part to provide an area affording access to the inside of the packet. The cigarettes are packaged together with a fan-folded pressure element of stiff paper placed between the group and one flank, which is rendered flexible along at least one line or portion of elastic deformation and able thus to compress and expand elastically along an axis of compression and expansion normal to the axis of the packet; as a result of the tension stored in the pressure element, the cigarettes are invested with a uniformly applied pushing force and biased toward the access area whilst a similarly uniform reaction force is directed against the inside face of the flank.
摘要:
A method and unit for combined transfer-turnover of packets of cigarettes, whereby the packets are fed successively by a first conveyor in a first direction perpendicular to a front first face of each packet and along a portion of a path extending through a transfer station, to which each packet is supplied in time with a respective suction seat carried by a second conveyor, which engages the first face of the packet by suction, and removes the packet from the transfer station in a second direction parallel to the first face.
摘要:
A method and unit for forming groups of products, whereby an orderly first succession of products is fed to an input of a conveying path along which a screw conveyor, rotating continuously about a respective axis and having a given number of variable-pitch threads, converts the first succession into an orderly second succession of groups as the products are fed along the conveying path.
摘要:
In a method of feeding wrapper material, typically as utilized by machines for the manufacture of tobacco products, a first and a second strip presenting two longitudinal side edges and of dissimilar transverse dimensions are advanced along respective predetermined first feed lines, positioned one relative to another in a direction transverse to the respective first feed lines in such a way as to bring about their alignment along one longitudinal edge and finally joined face to face before advancing together along a predetermined common feed line toward a machine unit.
摘要:
A method of rolling cigarette portions, wherein a first succession of first pairs of cigarette portions and a second succession of second pairs of cigarette portions are advanced in a direction crosswise to the respective axes of the cigarette portions, each first pair being defined by a first and a second cigarette portion coaxial with and a given distance from each other, the second succession being parallel to the first succession, and each second pair being defined by a third and a fourth cigarette portion coaxial with and the aforementioned distance from each other; the first pairs and the second pairs are partially engaged combfashion in a relative position in which each third cigarette portion is partially inserted between two adjacent second cigarette portions; a double filter and a respective projecting band are inserted between the first and second cigarette portions and between the third and fourth cigarette portions to form respective groups; and the groups, arranged in the first and second succession, are rolled along a common rolling bed to form double filter-tipped cigarettes.
摘要:
A machine for packing groups of cigarettes, wherein a step-operated first conveying device, having a pocket conveyor belt, a transmission pulley rotating about an axis of rotation, and a number of first conveying pockets, receives a given number of groups of cigarettes during a stop period, and feeds the groups, during a transfer period, to a continuous second conveying device having second conveying pockets and, for the second conveying pockets, a conveyor drum rotating about the axis of rotation; the first and second conveying pockets being aligned with each other and moving at the same speed during the transfer period.
摘要:
A method and unit for wrapping packets of cigarettes, whereby a succession of packets is fed continuously along a wrapping path having a straight input portion and a substantially curved output portion substantially tangent to the input portion at a transfer station for transferring the packets; the input portion extends through a wrapping station where each packet engages a respective sheet of wrapping material, and folds the sheet into a U so that two end portions of the sheet project rearwards from the packet; and each packet, together with the respective sheet, is transferred, at the transfer station, from the input portion to the output portion so that the two end portions of the sheet are maintained projecting rearwards from the packet.
