ABSTRACT:
In accordance with this invention, a method of transporting upright cylindrical articles is provided wherein the articles are fed from a mass at an upstream location into single file at a downstream location. The articles are fed in mass into the infeed of the deck of an air table. A lower air pressure zone is created on a first lateral portion of the deck plate between the upstream and downstream locations. A higher air pressure zone is created on a second lateral portion of the deck plate to cause the articles to move into single file in the first lateral portion. Velocity air pressure is used to move the single filed articles to a downstream location. The articles are held in single file with a directional mass volume of air. The pressure differential between the high and low pressure zones can be adjusted to vary the density of the articles at the infeed. A higher air pressure zone can be created in a downstream single file area to cause articles which are not in single file to move upstream to be placed in single file.
