Abstract
Rod-like articles, particularly cigarettes or cigarette filter rods, are conveyed in a stream in a direction transverse to their lengths at a speed which is progressively reduced, so that the height of the conveyed stream is increased. Prior to the reduction in conveyance speed the speed of individual articles is increased briefly to avoid damage from following articles. The speed reduction takes place in a path having divergent boundary walls.
