  • Patent number: 5769205
    Abstract: A continuous cigarette manufacturing machine wherein an input feedbox presents at least two outputs located at a loading station and for successively feeding respective groups of cigarettes directly into respective folding spindles on a wrapping wheel rotating continuously about its axis; the spindles are divided into groups, each presenting a number of spindles equal to the number of outputs of the feedbox; and the spindles in each group are activated by respective actuating devices moving with the wrapping wheel, and presenting respective spindle supporting elements oscillating differently in relation to the wrapping wheel by virtue of respective cam devices.
    Type: Grant
    Filed: October 10, 1995
    Date of Patent: June 23, 1998
    Assignee: G. D Societa Per Azioni
    Inventors: Bruno Belvederi, Giulio Barbieri
  • Patent number: 5404889
    Abstract: A device for perforating cigarette wrapping material by means of at least one-laser beam, whereby the wrapping material, in the form of a strip, is fed past a focusing head which is supplied with a pulsed laser beam by a laser source and focuses it on to the strip by moving the focused beam in a plane slanting in relation to the traveling direction of the strip; a shutter element, made of material impervious to the laser beam, being used for intercepting and restricting the focused beam to a sector of given shape and size, and so preventing the beam from impinging on given portions of the strip.

  • Patent number: 5247948
    Abstract: A filter assembly machine wherein one laser source emits a beam through a dividing device which divides the beam into two secondary beams directed respectively towards a cutting head for cutting a continuous strip into bands connecting double filters to cigarette portions, and towards a piercing device for forming ventilating holes in the bands.

  • Patent number: 5225649
    Abstract: A device for cutting a strip fed continuously on a roller through a cutting station where a series of at least partial transverse cuts are made successively in the strip by a cutting unit. On the cutting unit, a hollow rotary drum receives a laser beam emitted by a laser source, and focuses the beam at at least one point which, as the drum rotates, moves along an annular trajectory, the plane of which intersects the route of the strip at the cutting station and forms a given angle with a line intersecting the route of the strip.
