Abstract
A coverless air conveyor is provided for use with containers of varying heights. The conveyor has a jet board whose jets are substantially vertical with a slight downstream tilt and has sidewalls which form air dams to create a flowing body of air which envelopes and lifts the respective containers and moves them at a very precise speed, the speed being controlled by the small downstream vector of the air along the sidewalls of the containers. In one embodiment the sidewalls are tilted inwardly from bottom to top and air is provided in sufficient volume to vertically stabilize the containers as they move along the conveyor.
