ABSTRACT:
An apparatus for weighing mail pieces being advanced across a transport path including a weighing module having load cells, an in-feed drive module and a takeaway module. The scale platform is mounted independently of the in-feed drive module and the takeaway module, and the scale platform comprises an uninterrupted mail piece support surface. A control system is provided that acquires a mail piece weight signal when the lead edge of a mail piece reaches a sensor at the exit of the weighing module. Sensors also calculate the velocity of a mail piece as it leaves the weighing module, whereby speed of each mail piece is accelerated to its original speed and position in the mail transport path. Mail weighing throughput rates of up to 10 mail pieces per second are achieved.
