ABSTRACT:
A damperless, controlled speed, coverless, isometric air conveyor and method for controlling articles en masse or individually at a controlled speed is provided. A first set of louvers extend through the conveyor surface to a common plenum at an incline to the conveying surface so that the air passing through the louvers has downstream force vector of a first magnitude. A second set of louvers extend through the conveyor surface to a common plenum at an incline to the conveyor surface so that the air passing through the louvers has an upstream force vector of a second magnitude which is less than the first magnitude thereby creating a vector force differential in the downstream direction to cause movement of the articles in the downstream direction. An outboard row of louvers along each edge of the conveying surface may be angled in the inboard direction to cause a cross flow of air which creates an air barrier through which a single or sparse flow of articles must move, thereby limiting the speed of the single or sparse articles. The inboard cross flow of air also creates a low pressure drafting effect at the trailing edge of the sparse articles of the mass of articles to assist in maintaining them in an upright position.
