Abstract
A device and method are provided for transferring articles to and from an air conveyor. The device comprises a first plenum chamber, a second plenum chamber, and an air supply. The first plenum chamber has a transfer surface with a first plurality of perforations for directing air toward the air conveyor. The second plenum chamber is located at least above a portion of the air conveyor and has a plate with a second plurality of perforations for directing air away from the air conveyor. The air supply supplies air to the first plenum chamber to keep articles going down the air conveyor and to feed articles onto the air conveyor, and supplies air to the second plenum chamber to transfer articles off of the air conveyor.
