<p>In an apparatus having a moving mechanism for moving articles of mixed sizes from a stack of articles of mixed sizes along a feed path, a singulator apparatus including a feed deck; forwardly driving structure, connected to the feed deck, for contacting the articles along a first surface thereof and for moving the articles in a first direction along the feed path and over the feed deck; a reverse driving mechanism (45), connected to the feed deck, for contacting the articles along a second surface thereof and for driving all but one of the articles in a second direction opposite to the first direction so that only one of the articles at a time is moved by the forwardly driving structure in the first direction along the feed path and over the feed deck, the forwardly driving structure and the reverse driving mechanism being connected to the feed deck relative to each other to define a nip therebetween; apparatus for sensing if at least one of the articles is present in the nip; a control, operatively connected to the sensing apparatus, for operating the moving means to move articles from the stack toward the nip at times when the sensing apparatus does not sense the presence of the at least one of the articles in the nip and for preventing the moving mechanism from moving articles from the stack toward the nip at times when the sensing apparatus senses the presence of the at least one of the mailpieces in the nip. <IMAGE></p> |
