ABSTRACT:
An air table system which utilizes air jet openings in the table surface of a pattern configuration to lift, support and direct movement of objects, such as containers, to feed same from a plurality of sources to fewer destinations or vice versa. With suitable cover configuration, partially closed and open covers, movement of the containers around or to one side of blockades to accomplish controlled movement of the containers is made possible. The movement of objects can be further controlled by the use of the objects and/or side walls on the table to restrict air flow in conjunction with the solid cover portions to create selected higher air pressure zones and air flow paths to selectively move the objects. At a discharge end of the air table, a single file conveying zone is provided with air jets that blow air in the opposite direction to the normal flow of the objects to move them into single file.
