  • Patent number: 7578777
    Abstract: Filter elements made up of least two axially aligned plugs are advanced in succession by a feed unit along a first path and in a first direction, with the plugs oriented along a second direction transverse to the first direction, toward a garniture section extending along a second horizontal path and in a third direction, on which they are formed into at least one continuous rod which is then divided up by a rotary cutter into single composite filters. A transfer unit linking the feed unit and the garniture section comprises a conveyor, rotatable about a first axis parallel to the second direction, equipped with carriers each presenting at least one slot designed to admit one filter element; the single carriers are pivotable independently relative to the conveyor about a second axis parallel to the first axis, and about a third axis transverse to the first axis, alternating between positions in which the slot extends parallel with the second direction and with the third direction.

  • Patent number: 7325547
    Abstract: A curling device for a filter tip attachment comprises at least one blade-like element offered to a continuous strip of paper material at a selected contact zone in such a way as to deform the material as it advances, so that single tipping papers separated from the strip by a cutting unit of the attachment are given a curved profile and as a result more easily wrapped around and affixed to the assembled filters and cigarette sticks when these are joined together; the curling device also comprises a delivery system by which the contact zone is flooded with a cushioning fluid designed to favor a smooth sliding contact between the curling element and the running strip, and at the same time equalize the tensions in the strip preceding and following the contact zone.
