In a conveying system for transporting a sequence of articles to a suspending point in captured relation and then transporting them by vacuum suspension to a plurality of separate discharge stations, comprising the combination of: at least a pair of conveyor belts disposed in vertically spaced, overlapping relation to define an elongate nip therebetween extending from a capturing point to a suspending point, the upper of said belts extending beyond the suspending point and being provided with a series of openings extending longitudinally thereof; feed apparatus for feeding articles to the capturing point in sequentially spaced relation so as to be captured between the belts and transported therebetween to the suspending point; suction apparatus overlying the upper belt beyond the suspending point and defining a first chamber for subjecting the articles to vacuum through the openings to suspend them after they pass beyond the suspending point, the suction apparatus defining a plurality of further and separate chambers in spaced sequence beyond said suspending point; and control apparatus for independently controlling vacuum to the further suction chambers to release the articles sequentially at their respective stations beginning at that station located most remotely from the suspending point.
