A device for conveying flat objects in series and edge-on, in which the flat objects ( ) are moved in a conveying direction (D), while at the same time being separated each from the next by a spacing which is normally constant, has a synchronization system ( ) capable of compensating for any variations in spacing between two consecutive objects. The system includes two parallel rows ( ) of driven wheels ( A- C) made of elastically deformable elastomer and between which each object is gripped and moved in the conveying direction. Each wheel has a rotation spindle ( ), the position of which is fixed, and the wheels are rotated by a motorization system which is controlled to accelerate and/or retard the movement of each object between the two rows of wheels on the basis of a detection whether the front edge of the object has been early or late in passing a determined position upstream of the two rows of wheels compared with a time reference indicating the spacing between objects. The device may be used in a postal sorting machine operating in a synchronous mode.
