Abstract
A first transporting unit advances a series of stacks of paper sheets along a straight first path. A transfer conveyor can be lifted into the first path to divert selected stacks into the range of a second transporting unit which defines a second path making an oblique angle with the first path. The transfer conveyor is assisted by a pusher which is adjacent to the first path opposite the stack-receiving end of the second transporting unit and is movable at right angles to the first path to move the diverted stack sideways. Such stack strikes a yieldable bumper which expels it from the second path into the range of a third transporting unit serving to advance stacks in parallelism with or at right angles to the direction of movement of stacks along the first path. The orientation of selected stacks remains unchanged during diversion from the first into the second path as well as during diversion from the second into the third path.
