  • Patent number: 5310043
    Abstract: A feed apparatus including two feedscrews for supporting flat articles as they are moved along a conveyor. The two feedscrews are mounted in parallel and are spaced apart so that each feedscrew supports the flat articles along a different edge of the articles. The flat articles are maintained in a substantially vertical alignment throughout the conveyance. A suction pickoff station removes the flat articles one at a time from the downstream end of the feed apparatus. The two feedscrews turn at equal speeds and have equal pitches which separate the flat articles into groups between consecutive projections of the helical threads of the feedscrews.
