Abstract
A mailpiece feed device comprising a mailpiece-receiving deck for receiving a stack of mailpieces, conveyor rollers for conveying the mailpieces along a longitudinal referencing wall and towards a separator device designed to separate the mailpieces one-by-one from said stack of mailpieces and to convey them downstream, and, incorporated vertically in said longitudinal referencing wall, at least one friction roller of varying roughness, with its coefficient of friction decreasing from the top to the bottom of said longitudinal referencing wall.
