ABSTRACT:
By providing a package processing system with pulsed or intermittently applied package retardation or separation forces, a highly effective package handling system is attained which is able to process all packages without tearing, ripping, or damaging any surfaces or surface coverings. In its preferred construction, the packages are advanced in one direction and contact one or more rollers rotationally driven to the opposed direction in order to retard and separate stacked packages into a single level array. In addition, each roller is continuously raised and lowered out of and into engagement with the packages passing therebelow. By providing this pulsed or intermittent force, the packages are separated as desired, while also preventing damage to any package surface.
