Abstract
Selected individual stacks or selected groups of two or more successive stacks of paper sheets or the like are transferred sideways from a predetermined portion of a stack-supplying conveyor onto a facility employing one or more air cushion tables, or across the facility onto a second conveyor, in such a way that the transfer involves only a short-lasting interruption of advancement of stacks toward and in the predetermined portion of the stack-supplying conveyor, namely for an interval which is required to transfer the selected stack(s) from the predetermined portion of the stack-supplying conveyor onto the facility. This is accomplished by employing a stack evacuating system which is movable transversely of the conveyor or conveyors and of the facility and employs one or more flaps or other suitable transfer members pivotable or otherwise movable (a) downwardly to engage the side face(s) of the selected stack(s) for transfer from the predetermined portion of the stack-supplying conveyor onto or into the facility or onto the second conveyor and (b) upwardly and to a level above the stacks for return movement to a starting position.
