Abstract
Abstract Apparatus for handling mailpieces is provided, including a feed deck, having an upright wall, and including instrumentalities for successively feeding mailpieces downstream on said feed deck. The feeding instrumentalities include a device for engaging the lower major surface of respective mailpieces and a directional feed roller assembly; the latter including a roller and a flexible shaft. The roller extends from the flexible shaft for disposition in engagement with the upper major surfaces of respective mailpieces and cooperates with the mailpiece engaging device for urging the mailpieces against the upright wall for edge registration. The apparatus also includes instrumentalities for selectively gating mailpieces from the feed deck and for stacking the gated mailpieces on edge at a receiving station.
