Abstract: A method for applying adhesive on a wrapping band of a smoking article includes moving the band along a feed direction, the band has a longitudinal direction of extension, opposing first and second surfaces, a first plurality of portions having a first thickness and a second plurality of portions having a second thickness greater than the first thickness, the portions of the first and second pluralities being disposed alternately along the direction of extension. A nozzle having a delivery end, and the band are moved towards/away from each other between a first position, where the delivery end and the second surface are at a first distance which is less than or equal to the second thickness, and a second position, where the delivery end and the second surface are at a second distance greater than the second thickness. An adhesive is delivered on the first surface through the nozzle.

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.
