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.
