Abstract

A system for feeding a flat article has a suction chamber; a suction belt for picking up one of a plurality of flat articles which are stacked in a vertically standing state. The suction belt moves along the front surface of the suction chamber. The flat articles are carried over a transport path by the suction belt. At an upstream position in the transport path, the intervals between the flat articles are detected. First and second motors drive the suction belt, varying the rotational motor speeds. A roller along the transport path contacts the transferred flat articles in accordance with the interval which is detected by the detecting member.
