Abstract
A system for conveying mailpieces along a feed path includes a plurality of conveyances. A first conveyance is operative to convey mailpieces along the feed path and includes a singulating and drive belt. The singulating and drive belts define a throat for singulating a mailpiece from the stack of mailpieces. A second conveyance accepts mailpieces from the first conveyance and conveys singulated mailpiece downstream of the first conveyance. The system further includes a series of sensors extending from the first to the second conveyance for issuing a gap signal indicative of the relative spacing between sequential mailpieces along the feed path. Additionally, the system includes a means, responsive to the gap signal, for developing a variable opposing force between the singulating and drive belts to optimize singulation of mailpieces along the feed path.
