Abstract
A conveyor for lightweight objects, such as plastic beverage containers, includes an upward facing conveyor surface and a drive for causing the conveyor surface to move. An air suction device located below the conveyor surface draws air through the conveyor surface. The drawn air creates an object-stabilizing suction force on an object located on the conveyor surface when the conveyor moves relative to the air suction device. The conveyor has provision for changing the suction force imposed on the object while it is being transported on the conveyor surface.
