Abstract

An apparatus is provided which both floatingly supports a web, and maintains the web in a substantially straight path as it travels through a dryer. The apparatus comprises a steerable air bar assembly comprising: i) one or more adjustable air bars, each having an elongated surface from which air may be discharged, said surface being in opposing relation to the running web, and each having two ends; ii) air supply means, in fluid communication with the air bars; and iii) adjustment means for altering the orientation of the elongated surfaces of the adjustable air bars with respect to the running web, In a preferred embodiment the orientation of the, surfaces is adjusted such that each said surface rotates about an axis which is substantially parallel to the longitudinal centerline of the running web. Said steerable air bar assembly is positioned in a web dryer such that the web is guided through the dryer in a substantially straight path. A plurality of such steerable air bar assemblies can be used in a web dryer. The dryer can also include one or more fixed air bars.
In a preferred embodiment of the invention, the apparatus further comprises in combination with the steerable air bar assembly, back pressure means for creating an opposing force to urge the web back to a substantially centered position. Said back pressure means preferably comprises one or more edge dams preferably disposed at or near the ends of one or more fixed air bars in the web dryer.
