Abstract (en)

[origin: WO03018449A1] The invention relates to a method and a device for identifying overlap during the successive transport of flat mail in a double belt system. After edges have been detected on both sides of the transport path and after the distances between the detected edges and the respective guiding front edge measured by a light barrier have been determined, both sides of the longitudinal sides of the mail are acted upon with different transport speeds, ensuring that the minimum gaps are maintained. The distances between the edges and the guiding front edge are then re-measured. A double feed is detected if there is a change in distance.
