ABSTRACT:
An active web stabilizer including a structure having a leading edge and a working surface coupled by a curved surface, the working surface being positioned proximate to a passing web. An internal pressurized air duct extends along the working surface orthogonally to the passing web. An air nozzle is provided at the leading edge and is in fluid communication with the air duct, the nozzle directing air flow around the curved surface and along the working surface. The air duct includes first and second chambers separated by a perforated baffle. An extension surface extends from the working surface and includes a trailing end which is angled away from the passing web. A comb is associated with the nozzle to promote web spreading.
