Abstract: A method of stabilizing a low strength sheet which involves passing the sheet under an apparatus having a width and a top surface and moving in a first direction at a rate sufficient to entrain air. The apparatus includes an airfoil adapted to extend along the top surface of the sheet. The airfoil, in turn, includes:a bottom surface adapted to extend along a portion of the top surface of the sheet;a first surface extending a first distance from the bottom surface at a first juncture;a second surface extending a second distance from the bottom surface at a second juncture; anda top surface extending from the first surface at a third juncture to the second surface at a fourth juncture. The first distance in general is less than the second distance.
