  • Patent number: 4144695
    Abstract: In the hinged-lid type cigarette packets, the upper flap protruding from the front wide side of the inner wrapper should, for convenience in the use, be folded over the upper flap protruding from the rear wide side of the same inner wrapper. In some of the conventional soft type packeting machines the folding disposition of the upper flaps is exactly opposite to the one above described, and the present invention provides for a device which allows the use, in a hinged-lid type packeting machine, of a rotating wrapping head normally used in the soft type packeting machine, since said device reverses the folding disposition of the upper flaps.

  • Patent number: 4086744
    Abstract: A device for re-orienting and redistributing hinge-lid packets of cigarettes for application of sealing strips or revenue stamps to the hinge-lids. A first conveyor unit receives the packets, disposed on edge and contacting one another with their wide sides, and having their hinge-lid portions facing away from one side of the conveyor unit. The first conveyor unit moves the packets gradually to a second conveyor unit. This unit moves more rapidly than the first, to space the packets apart. It cooperates with a deflector disk and a narrow overhead belt to turn each packet so that it travels to the delivery end of the second conveyor unit, with the hinge-lid portion facing forward, toward a machine for applying a seal strip or the like.

  • Patent number: 4056915
    Abstract: A compensating store device for cigarettes, between cigarette manufacturing machines and machines for packeting the cigarettes, wrapping the packets and making and wrapping packs of wrapped packets. The store device comprises a cylinder rotating about a vertical axis and having vertical, radial cigarette storage compartments, circumferentially distributed. A cigarette delivery channel at the top of this cylinder feeds cigarettes from a feeding conveyor run to the compartments, and tilts gradually so as not to loose its free and open, cigarette-feeding connection to the compartment in the rotating cylinder. Similarly, a cigarette-removing channel at the bottom of the cylinder is tiltably mounted. Between these channels, successive, horizontal rods are moved into, downwardly along, and ultimately from each compartment, with the aid of a further tilting mechanism, to provide supports for the cigarettes stored in the compartments.

  • Patent number: 4020608
    Abstract: A device for sealing wrapping material on pieces of candy or similar products, in what is known as the "soap" style of wrapping, and for exiting the products, in their sealed wraps, from the wrapping machine. Each wrapped product is first received in a correspondingly dimensioned pocket of a horizontal conveyor disk, which intermittently conveys the product along a sequence of plates, comprising a presser plate, a first heat-welding plate, and a first cooling plate. The presser plate eliminates bulges of the sides of the product, created during the wrapping. It presses other sides of the product, with folded tabs of the wrap thereon, into the pocket. The heat-welding plate then seals portions of the wrap on a then exposed side of the product.
