Abstract
A method and an apparatus for accumulating reams of paper sheets into stacks. A file of reams is fed by the upper reach of a belt conveyor which is flanked by a shifting arm and an elevator platform. The arm is caused to move transversely of the conveyor and the delivery of succeeding reams can continue without awaiting retraction of the shifting mechanism. The reams are accumulated in the stacking region on an elevator mechanism and are raised by the elevator mechanism to a delivery position above the receiving position after a desired number of reams have been accumulated on the elevator mechanism. The accumulated reams are removed from the elevator mechanism at the delivery position and the elevator mechanism is lowered back to the receiving position after the accumulated reams have been removed, without awaiting retraction of the removing mechanism.
