  • Patent number: 4506779
    Abstract: Apparatus for transferring bar shaped articles from one conveyor to another wherein the two conveyors are each provided with equally spaced suction housings for holding the articles with the spacing in one conveyor being different from the other. The apparatus comprises a link-up conveyor which includes a first and a second rotating element that revolve in the same direction at identical angular velocity, around separate parallel axes. To the perimeter of the first rotating element are pivoted equally spaced cranks, each provided with a suction housing for holding and releasing an article. Each crank is connected to the second element by a link which, as the link-up conveyor rotates, causes it to oscillate at such a rate as to match the velocity of the crank suction housing to that of the suction housings of the two conveyors in the positions in which the articles are transferred thereto or therefrom by the link-up conveyor.

  • Patent number: 4442848
    Abstract: A cigarette-making machine in which tobacco, in part from a carding unit and in part from a plurality of channel elements, is supplied to the upper end of a shaft. The channel elements, to which recycled tobacco can be supplied, are located alongside one another and communicate laterally with the shaft below the shaft top. A vibrator device is associated with each channel element. The frequency of vibration of each vibrator is a function of the level of tobacco within the shaft beneath the tobacco delivery end of each channel element in communication with the shaft.

  • Patent number: 4433694
    Abstract: A device for applying filters to cigarettes by means of adhesive connection bands of a type comprising a peripherally grooved conveyor roller which transfers to a position, referred to as rolling position, units comprising two axially aligned cigarettes with the interposition of a filter section. At the rolling position an element, referred to as counter-rolling element, defines in combination with said conveyor roller a passage at which said bands are rolled up about the units. By means of a cutting device cooperating with said conveyor roller, the bands are provided by a paper web fed from a reel.After receiving adhesive on one face by a gluing device and before reaching the conveyor roller, said web skirts the surface of a heated rotating roller which causes the partial evaporation of the solvent in the adhesive.

  • Patent number: 4431010
    Abstract: The device for applying cigarette filters by use of glued junction hands is of the conventional type and comprises a rotating main drum for receiving on grooves provided on its cylindrical surface a plurality of units disposed in parallel arrangement with the axis of said drum. Each unit, formed by one cigarette, a filter section and by another cigarette coaxially disposed, is wrapped up by a band of adhesive paper material covering said filter section and about 1/8" of the end sections of the two cigarettes. The rolling operation of the band is carried out within a rolling passage defined at one side by said main drum and at the other side by a web slidingly guided along a curved surface concentric with the main drum.The improvements according to the invention provide means for retaining said web adhering to said guide and sliding surface, said means being of magnetic or suction type.

  • Patent number: 4395177
    Abstract: The apparatus comprises a continuous path, divided into a first rising section and a second substantially horizontal section, having a conveyor extending there along and carrying one or more pushers adapted to withdraw individually folded and flattened cartons from a container magazine provided and arranged at the top of the rising section. At the junction location between the two sections, movable supports are provided which receive, when at a first position arranged in continuation of the rising section, individually folded and flattened cartons and transfers the latter, when arranged at a second position in which said supports are arranged parallel to the conveying along the substantially horizontal section, again on the conveyor without said cartons being left by the one or more pushers. This assures a correct arrangement of said cartons on said conveyor downstream of the junction location.
