Abstract
The present invention concerns a mailpiece sorting and stacking apparatus. The sorting and stacking apparatus has a series of stacking bins. Each stacking bin is designed to include a set of kicker fingers that engage the trailing ends of the mailpieces traveling towards a stop registration wall in each stacking bin. The stop registration wall in combination with the spring force exerted by the kicker fingers against the trailing ends of the mailpiece cause the end of each mailpiece to engage the outside surface of a pressure mailpiece conveying roller. The pressure mailpiece conveying roller is part of the conveying roller assembly leading to the stacking bin. The periphery of the pressure mailpiece conveying roller along with the deflection force against the trailing end of each mailpiece caused by the kicker fingers causes each mailpiece to stack against a pressure paddle inside the stacking bin.
