A device (10) for non-contact support of a continuous moving web (38) of . material employs an air clamp stabilizer (10) that includes a Coanda slot (1 8) and a backstep (16) that is located downstream of the direction of the airfl ow extending from the Coanda slot (18). This configuration permits a Coanda jet to expand and to create an additional suction force. Vortex formation may al so occur which further contributes to the strength of the suction force. As the web (38) passes the stabilizer, an area of the web material rides on an air bearing that is maintained above the stabilizer surface (12A,12B,14) and downstream of the backstep (16).
