ABSTRACT:
A plurality of transfer conveyors are arranged at right angles to and spaced along a main conveyor for transferring selected sheets from said main conveyor and either dropping them in a reject bin or stacking them in separate piles depending upon the size of the sheets. The transfer conveyors overlie the main conveyor and operate to pick up sheets from the main conveyor by Bernoulli's principle and permit them to slide by gravity to the stacking or reject means while supported in non-contacting relation by the nozzles. The nozzles are selectively actuated in groups to achieve the pickup, reject and stacking functions.
