ABSTRACT:
A continuous scalloped stream of paper sheets is divided into a succession of discrete sections by an accelerating device in cooperation with one or more belt conveyors which receive the sections. The accelerating device has an elongated rubber pad attached to an endless chain conveyor which can move the pad into the path of movement of the stream of sheets toward the belt conveyor or conveyors. The belt conveyor(s) and the chain conveyor are accelerated from the speed of the advancing stream to a higher second speed as soon as the trailing end of the section which is about to be separated from the stream is engaged by the trailing end of the pad on the chain conveyor. The chain conveyor and the belt conveyor(s) are decelerated back to the speed of the stream as soon as the entire freshly formed section is transferred onto the belt conveyor(s) and before the fresh leader of the stream reaches the discharge end of the conveyor for the stream. The acceleration of sheets which are to form successive sections to a speed exceeding the speed of the stream prevents the accumulation of piles of overlapping sheets at the leader of the stream upon separation of a section therefrom.
