ABSTRACT:
Apparatus for moving discrete sheets along a first path has a rotary hollow cylindrical foraminous barrel which is located below a portion of the first path and is adjacent to the inlet of a second path along which selected sheets move when a chamber which is rotatable relative to and is located in the interior of the barrel is connected with a suction generating device. The chamber reaches the first path at the inlet of the second path together with the leaders of successive sheets and can be connected with the suction generating device by a solenoid-operated valve which is actuated by a switch which, in turn, is actuated by an adjustable cam on the rotary core which defines the chamber. When the chamber is sealed from the suction generating device, it is connected with a source of slightly compressed air so that streamlets of air which issue from the barrel compel successive sheets to remain in the first path. The barrel is rotated at a peripheral speed which matches the speed of the conveyors of the transporting systems defining the first and second paths, preferably by a belt conveyor which is adjacent to a part of the first path as well as to a part of the second path.
