  • Patent number: 5533613
    Abstract: In a cigarette packet of the type with a hinged lid composed of a rigid box and a soft inner wrapping directly enveloping the cigarettes, the lid end is reinforced internally by a frame lodged between the wrapping and the box, and the packet often assembled with a leaflet or coupon inserted between the frame and the wrapping. To ensure that the coupon does not slip out of place as assembly operations proceed, the frame or the coupon itself is fashioned with at least one slot position to interlock with a corresponding part of the coupon or the frame, accordingly.

  • Patent number: 5515965
    Abstract: In a cigarette packet that consists of a single wrapper with an easy opening tear ribbon, applied to the inside surface, the wrapper exhibits break lines coinciding one with each longitudinal edge of the ribbon, and incisions positioned to coincide with the opposite ends of the ribbon; also applied to the inside surface of the wrapper, at least over the areas exhibiting the incisions, are respective ribbon patches able to restore the continuity of the wrapper where broken by the incisions, in such a way that the contents of the packet will remain isolated from the external environment until the ribbon is removed.

  • Patent number: 5497598
    Abstract: Seal labels are affixed to containers by means of equipment comprising a system of conveyors serving to direct a succession of the containers along a predetermined path, and a feed device by which gummed labels are supplied to a fixing station occupying a position alongside one part of the selfsame path. The feed device affords a recess located between two points against which the two ends of each label are restrained, and operates in conjunction with a first push rod by which each container in turn is displaced from the conveying path, directed forcibly against a relative label supported by the device and caused to penetrate the recess to a given depth together with the label. Thereafter, the container is ejected from the recess and repositioned on the conveying path by a second push rod.

  • Patent number: 5473862
    Abstract: Divisible packs consisting in two wrappers breasted frontally one with another are conveyed broadside, singly and in succession, to the point of being taken up between paired belt loops carrying teeth which are timed to impinge on the two wrappers and bring them into vertical alignment. Thereafter, the pack draws level with an applicator station where labels are affixed to the now perfectly matched end faces of the wrappers, then passes on to a further station at which correct application of the labels is verified by two pneumatic control elements: these consist in suction cups or nozzles connected to respective transducers which, by sensing changes in the pressure levels registering at the end faces of the wrappers, will detect any pack from which either or both of the labels may be missing.

  • Patent number: 5447673
    Abstract: A cigarette packet of the rigid type having a hinged lid is fashioned in a mold, composed of a bottom die and a top die which combine to create two distinct voids and a slender channel by which the voids are interconnected. A moldable material is directed between the bottom die and top die, filling the voids and the channel completely and resulting in the formation respectively of a container, a lid, and a hinge connecting the lid to the container.

  • Patent number: 5443681
    Abstract: A slender ribbon currently in use and nearing depletion is spliced automatically with a similarly slender new ribbon, held motionless and ready to feed as the replacement for the ribbon in use, by a device comprising a pair of jointing rollers positioned in symmetry on opposite sides of the two ribbons and disposed normally in a standby configuration, stationary, which allows the ribbon in use to pass freely between their two peripheral faces whilst the leading end of the new ribbon is restrained by one of the rollers and distanced from the ribbon in use through the action of an adjacent pulley; in a second configuration, the two rollers contrarotate synchronously and in a direction concurrent with the feed direction of the ribbon in use, completing one full revolution during which the new strip is accelerated initially by the restraining roller to a feed velocity matching that of the ribbon in use, whereupon the two ribbons are sandwiched between two stickers and pinched tight.

  • Patent number: 5238355
    Abstract: An apparatus for feeding packaging machines with stacks of cutouts includes a centering member for supporting members of a plurality of stacks of cutouts, the stacks being arranged mutually side by side so as to form parallel and mutually adjacent rows on the supporting members; a unit for removing and transferring individual rows, provided with a head fitted with pushers which are arranged vertically side by side and are adapted to move a single row of stacks in a horizontal transfer direction; a switching platform which is adapted to cooperate with the pushers so as to receive the row of stacks and allow its transfer to a belt for input to the packaging machine.

  • Patent number: 5190430
    Abstract: The apparatus for feeding packaging machines with stacks of sheet material has a unit for the removal and transfer of stacks of sheet material which are arranged mutually side by side on supports and are individually wrapped by respective bands. The removal and transfer unit has a head which is vertically and horizontally movable and has grip elements for removing individual stacks from the supports and for transferring them to a feeding station of the packaging machine. A station for cutting the band is arranged ahead of the feeding station.
