ABSTRACT:
An apparatus for sequentially feeding cards from the bottom of a vertical stack, which includes a card transport drum positioned below the stack so as to support the forward edge portion of the bottom of the stack. The drum includes a set of suction openings disposed transversely across the outer peripheral surface of the drum, and the openings are of oval outline. To sequentially feed the cards, the drum is rotated so that the openings move across the bottom of the lowermost card and the suction grips and holds the lowermost card on the surface of the drum, to thereby advance the lowermost card from the stack. The oval outline of the openings helps ensure that only the lowermost card is gripped and advanced by the suction openings. The apparatus also includes a vertically adjustable gate assembly mounted to overlie the forward edge of the stack and so as to define an outlet gate with respect to the drum, and a pair of rollers is mounted to the gate assembly which serves to reduce the weight of the stack at the gate.
