Abstract
An air bar web guide provides lateral adjustment of a running web passing through the guide so that the web exiting the guide is maintained in a constant lateral position. The path length of the web passing through the guide is maintained constant and does not vary from one edge of the web to the other edge. The guide includes a pair of idler rolls journaled for rotation about parallel axes and a pair of air bar guides also maintained parallel to each other. The air bar guides are mounted for pivotal movement with respect to the idler rolls to angulated positions when lateral adjustment of the web is required. A cam system driven by a linkage responsive to the angulated position of the air bar guides moves one of the idler rolls toward and away from the other idler roll to maintain a constant path length of the web passing through the guide system.
