Abstract of the Disclosure An adjustable apparatus is provided for uncurling,both edges of a running web to insure that the web moves in a flat or open width condition for proper drying. A plurality of transversely extending telescopic tubes are mounted in closely spaced parallel relation with respect to the face of the running web. The tubes are connected to a common plenum chamber which, in turn, is connected to a blower driving recirculated vapor or air through the tubes under pressure. The outer end of each tube is provided with a movable nozzle for directing a jet of air or vapor against the opposing selvedges, forcing them flat against a supporting conveyor. The nozzles are connected to a common support and drive mechanism which allows transverse adjustment of the nozzles to accommodate webs of different widths.
