A device ( ) for removing flat objects from a stack includes a magazine ( ), in which flat objects are stacked on edge to be serialized, and a vertical destacking plate ( ) disposed directly in front of the magazine ( ) and against which the first object (O ) of the stack is pressed. The first object (O ) of the stack is ejected in a direction (E) perpendicular to the direction of advance (D) of the stack of flat objects in the magazine ( ). The device ( ) also includes means ( ) for measuring the thickness of each flat object pressed against the destacking plate ( ). This thickness measurement serves as a feedback control for the movement of the stack of flat objects in the magazine ( ). The device ( ) may be used in a postal sorting machine.

The device for the high-speed conveying of post envelopes ( A, B) comprises a fixed sole plate ( ) extending along the path which the conveyed envelopes follow and along which the envelopes, standing on edge and arranged in series, glide, a motorized endless reference belt ( ) stretched along one side of the sole plate, a motorized endless press belt ( ) stretched along the other side of the sole plate, and a series of elastically deformable elastomer wheels ( ) for elastically pressing against the reference belt in such a way as to grip the envelopes arranged on the sole plate between the reference belt and the press belt. The wheels ( ) each have a hub mounted to rotate on a stationary spindle, and an annular tread strip in contact with the press belt, the hub and the annular tread strip of each wheel being connected by elastically deformable circular-arc-shaped fins. The two ends of each fin, which are for connection to the hub and to the annular tread strip of the wheel, lie on a radius of the wheel.

The deice for conveying flat objects edge-on in series at high speed between an entry (A) and an exit (B) of a conveying path comprises a routing system for diverting some of these flat objects towards another exit (B&prime;) between the entry and the exit of the conveying path. This system comprises two mobile flaps ( ) kept mutually parallel and arranged between the entry and the exit of the conveying path, and two motorized endless belts ( ) moving between these two flaps and between which the flat objects conveyed are gripped, these two flaps being mounted so that they can pivot so as to route the flat objects either towards the exit (B) of the conveying path or towards the other exit (B&prime;). A stationary post ( ) is located at the point where the flat objects are routed downstream of the mobile flaps between the entry and the exit of the conveying path. The exit (B) of the conveying path is distant from the stationary post ( ), and one ( ) of the motorized endless belts extends beyond the stationary post as far as the exit of the conveying path, and this makes it possible to ensure the continuity of the conveying of the envelopes exiting the routing system.
