Abstract
A method and apparatus is presented for stabilizing a free loop of web material between two web handling devices. The present invention employs fans or other forced air sources, directed toward the inner surface of the free loop, to maintain a stable free loop shape, thereby permitting simplified web handling and more accurate control of the web feeding or web take-up rate.
