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.
