A configuration for the transport and simultaneous alignment of sheets has a straightedge, at least one conveyor belt disposed slightly at an angle to the straightedge in the direction of movement of the sheets, and an air suction device. The conveyor belt exhibits open transverse slots on its upper side carrying the sheets. The upper half of the conveyor belt runs in a guide channel that is open in an upward direction, and the transverse slots are connected to the air suction device in such a way as to permit the flow to take place. A controller is provided to control the supply of air in the area of the transverse slots.
