Abstract
An apparatus and method for stabilizing and changing the direction of a web moving in a web path between web handling devices. The apparatus includes an airfoil having a bulbous front end tapering to a narrowed rear end, the airfoil having first and second oppositely facing surfaces. A coplanar surface extends from the rear end of the airfoil to define an active surface with the second surface of the airfoil. The web is arranged to move in spaced relation with and along the active surface such that the interaction between the active surface and the boundary layer air associated with the moving web serves to both stabilize and alter the direction of the boundary layer air and the moving web.
