  • Patent number: 4344521
    Abstract: Apparatus for conveying rod-like articles, especially cigarettes, includes parallel conveyors for streams of articles and two transfer conveyors which together re-orientate articles in one stream for combination with articles in the other stream. The transfer conveyors each convey articles on a curved path having a substantially vertical axis and include guide means for elevating the outer ends of the articles on the path. In another arrangement parallel opposed conveyors deliver articles to a downwardly-extending junction provided with retractable conveyor bands which may initially extend across the junction to aid filling. The stream on one of the opposed conveyors may be delivered from a further parallel conveyor by a rotary disc transfer conveyor which turns articles through 180 degrees for delivery to the one conveyor. The apparatus is particularly useful for tip-turning of cigarettes at the exit on a filter cigarette assembling machine.
