Abstract

An on-edge stacking machine having a mailpiece input device to release mailpieces, one at a time, to a stacking deck for stacking. A speed monitoring device and a sensing device are used to monitor the moving speed and the arrival time of a mailpiece from the input device to a reference point of the stacking machine. Based on the moving speed and the arrival time, a displacement distance of the arriving mailpiece is computed. A segmented roller is then used to move the arriving mailpiece into the bottom of the stack in a two-part motion cycle, based on the displacement of the arriving mailpiece.
