ABSTRACT:
Method and apparatus for smoothing and laterally guiding a longitudinally moving web of material wherein the web is longitudinally moved in a generally upward vertical direction past first pressurized fluid discharge manifolds disposed adjacent the web path on either side of the plane of the web to continuously direct streams of pressurized fluid, such as air, outwardly of the central portion of the web and toward side edges of the web to smooth and remove wrinkles from the same, and second pressurized fluid discharge manifolds located adjacent at least side edge portions of the web path for intermittently directing streams of air across opposite faces of the web toward one or the other of the side edges thereof, in response to web edge sensing means, to laterally move and guide the web during its longitudinal travel.
