Abstract
A vacuum combiner is provided comprising a vacuum chamber with a wear surface forming one side thereof, a plurality of air pervious conveying surfaces, a guide rail extending across the conveying surfaces toward a single file lane, and a vacuum suction region in the wear surface on an upstream side of the guide rail. The vacuum suction region extends approximately an article width upstream of the guide to prevent article tipping without impeding article movement between the conveying surfaces toward the single file lane.
