Abstract
A system for conveying mailpieces along a feed path including first and second 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 or 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 to vary the velocity of the drive belt based upon the location of the gap signal along the series of sensors.
