ABSTRACT:
A mail accumulating device having a number of stream forming units, each of which has a pair of powered belts superimposed at a point of contact defining the input of the unit. Each stream forming unit is provided with a sensor for detecting the passage of a mail item into the unit, and for generating a signal for activating the belts, thereby moving the mail items retained on the belts from the input to the output of the unit in discrete steps, and forming a group of overlapping mail items with the leading edges separated by a substantially constant distance. The device also includes a number of conveyor belt devices, each of which has an input communicating with the output of a respective stream forming unit, to enable the conveyor belt to receive a group of mail items at the input and feed the group of mail items to an output of the conveyor belt device to define an accumulating unit.
