Abstract
An air stabilization system employing two parallel, opposite facing Coanda nozzles, that are positioned adjacent a flexible moving web, with each nozzle exhausting gas at opposite directions, subjects the moving web to opposing forces effective to stabilize the web. Each nozzle includes an elongated slot that is parallel to the path of the moving web. The two Coanda nozzles serve as separate points along the machine direction for controlling the height of the moving web. By modulating the flow, pressure and other parameters of gases exiting the Coanda nozzles, the shape of the moving web between the nozzles can be manipulated to present a planar contour for measurements. The air stabilization system can be incorporated into a scanner head to measure the caliper of paper, plastic, and other flexible web products.
