Abstract: A method of processing mailpieces in a sorting installation including a feed inlet magazine (4) in which the mailpieces (1) for sorting are placed in a stack and on edge so as to be put in series in a sorting conveyor (5), the mailpieces (1) in series and on edge in the sorting conveyor being directed towards sorting outlets having respective stackers (6). The mailpieces (1) for sorting that arrive at the feed inlet magazine while stored in a tray (3) are taken in handfuls from the storage tray to be positioned in a stack and on edge in order to be put into series. The mailpieces (1) sorted into a stacker of a sorting outlet (6) are also transferred in handfuls from the stacker towards a storage tray (3) for the purpose of being recycled to the feed inlet magazine (4) from the sorting outlet (6) having a stacker.

Abstract: An adjustment method for adjusting the heights of the nipping belts in a transport conveyor that moves flat articles in series and on edge, so that a transport height is substantially constant for the flat articles. The method causes the conveyor to operate empty in such a manner that the nipping belts of heights that are to be adjusted run without any flat article in the conveyor, emits two parallel and superposed light beams towards a belt of height to be adjusted, spaced apart by a certain distance equal to the width of the belt between the two opposite edges of the belt to be adjusted, the light beams emitted from a portable tool, and manipulate a tensioner adjusting the belt so as to move the belt heightwise while it is running empty until the two light beams intersect respective ones of the two opposite edges of the belt.

Abstract: A method of sorting mailpieces amongst N logical sorting destinations with a sorting machine including a mailpiece conveyor that serves M sorting outlets, each of which is provided with a removable mailpiece storage tray that is handled by a tray conveyor, where M is less than N, consists in detecting that a current mailpiece to be sorted has a certain logical destination that is said to be “overbooked” and that is not associated with a sorting outlet, and in dynamically allocating to said overbooked logical destination a certain sorting outlet of the machine that is occupied by another logical destination. In said certain sorting outlet, a tray change is made and the tray extracted from said certain sorting outlet is put on standby on a loop of the tray conveyor.

Abstract: The invention relates to a stacker device comprising a support surface (24, 24?) on which a stack (P) of flat articles (O1-On) is formed as the flat articles are inserted and pushed on-edge one-by-one in a main direction (D) against a retaining element (18) for retaining the stack, which element is provided at the front end of said stack. The support surface (24, 24?) is mounted to be free to move in translation in the main direction (D), being moved synchronously with the movement of the retaining element (18) in said direction, thereby imparting excellent stability to the stack formed in this way. The retaining element (18) is also mounted to move relative to the frame (10) and associated with means arranged so as to exert a return force on the stack of flat articles (O1-On) in such a manner as to retain it. The invention also relates to a postal sorting machine equipped with at least one such stacker device.

Abstract: In a method of sorting mailpieces in a plurality of sorting passes in a postal sorting machine (10) provided with sorting outlets so as to sequence the mailpieces in the sorting outlets for delivery in the order of a delivery round, delivery points defining the delivery round are grouped together into disjoint subsets of delivery points. For the various sorting passes, the delivery points of each subset are associated every time with a common sorting outlet. Statistical data (11) is retrieved from a memory of the machine, which data is associated with respective ones of said delivery points, and is representative of the volume of mail delivered in association with the delivery point in question, and successive delivery points are grouped together into a common subset of delivery points by taking account of said statistical data associated with said delivery points.
