Abstract
A web-steering mechanism, particularly for the endless belt of a xerographic copier, uses two rolls to hold the belt under tension. An idler roll is designed to rotate about an axis which is at a small angle to a tilt axis of the idler roll assembly. Small tilting movements of the idler roll assembly, under the control of a servo-motor are effective to alter the angle at which the web enters and/or leaves the roll, to cause the web to walk along the tilted roll.
