ABSTRACT:
A conveyor structure of the roller type includes an alignment device for maintaining relatively flat objects in aligned positions with respect to each other. The device includes a plurality of second rollers disposed between the rollers of the conveyor, the second rollers being eccentrically rotatable about axes extending longitudinally or perpendicular to the axis of the first rollers. The second rollers move upwardly between the first rollers to engage the flat underneath surface of articles traveling on the conveyer to lift them up and to move them laterally into engagement with a positive stop position to one side of the conveyer, whereby the objects are then relatively aligned with respect to each other.
