Abstract: The present invention relates to a method and a device for stacking flat mailings, in which the thickness of each individually conveyed mailing that is to be stacked is detected within a main control loop. The underfloor belt is displaced away from the stacking location by a distance that corresponds to the measured thickness minus a specific distance by means of a stack support for the arriving mailing. The stacking force is measured at different heights in the area of the stacking roll in a static correcting control loop and is re-regulated by moving the underfloor belt within set point values established for the allowed stacking force ranges once each mailing has reached the stop.

Abstract: The present invention relates to a system and method for stacking objects in a stack. The objects may be flat flexible objects with front and back edges being narrower than side walls. Accordingly, the objects may comprise mail pieces. Per the invention, the mail pieces are directed to a stacker. The stacker comprises an impact wall with abutting installation and limiting walls. Accordingly, the stack may be formed therebetween with the installation wall being urged towards the limiting wall so as to sandwich the stack. At least one diverter element or vain is included upstream from the stacker. A roller of a conveying element is positioned upstream from the upper most vain. An object is directed towards the impact wall. When the objects leading edge impacts the wall, the vain or roller closest to the trailing portion of the object causes the trailing portion to be urged towards the stack. The vains may be pivoted while the roller made to turn in a select manner.
