The device for conveying flat objects in series and edge-on, in which the sa id flat objects (12) 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, comprises a synchronization system (2) capable of compensating for any variations in spacing between two consecutive objects, this system comprising two parallel rows (3, 4) of driven wheels (3A-4C) made of elastically deformable elastomer and between which each object is gripped an d moved in said conveying direction. Each wheel has a rotation spindle (6), th e 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 as to 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 which indicates the spacing between objects. Application to a post al sorting machine operating in synchronous mode.
