Abstract
Abstract A conveying system includes a first continuous belt supported horizontally at two ends by a pair of rollers. A plurality of balls are mounted to the belt for rotation. A second conveyor belt is positioned within the space between the rollers defined by the upper and lower portions of the first belt such that the upper surface of the second belt contacts the balls of the first belt. As the two belts are rotated, articles may be conveyed by the first belt and rotation of the balls by the second belt causes the articles to move diagonally over the upper surface of the first belt whereupon they may be justified to one side or the other of the belt.
