  • Patent number: 8596635
    Abstract: A system for conveying mailpieces along a conveyance path and singulating a mailpiece from a stack of mailpieces along the conveyance path. The system includes a first conveyance for conveying mailpieces at a variable velocity and a second conveyance, downstream of the first conveyance, for conveying mailpieces at a constant velocity along the conveyance path. A series of optical sensors extends from the first to the second conveyance and is operative to issue a gap signal indicative of the relative spacing between sequential mailpieces along the conveyance path. A processor is responsive to the gap signal and is operative to control the first conveyance to decrease the relative spacing between sequential mailpieces when the gap signal exceeds a threshold value.
