  • Patent number: 4458803
    Abstract: A packaging conveyor for cylindrical articles serving to maintain cylindrical articles such as stacks of cups or the like in a desired orientation with the longitudinal axis of the cylindrical article maintained perpendicular to the direction of movement of the article along the conveyor. The conveyor is formed as a flight conveyor with a first run of flights spaced apart a distance less than 100% and greater than 25% of the diameter of the cylindrical article to be oriented, so that the cylindrical article will fall partially through the spacing between adjacent flights of this first run. A second run of flights spaced apart a distance less than the spacing between the flights of the first run is mounted for movement with the flights of the first run, receiving oriented articles from the first flight run, so as to raise the level of the articles to lie on a plane along the top of the flights.
