ABSTRACT:
A device for tracking a belt moving along a path in a predetermined direction, including a member including opposed arcuate marginal regions and a central region interposed therebetween. The opposed arcuate marginal regions have a first coeffecient of friction and the central region has a second coeffecient of friction less than the first coeffecient of friction so as to maintain the belt moving over the member in substantial alignment with the predetermined direction. A second belt path defining member or roller may further contribute to straight belt tracking. Plural belt/roller systems may be used cooperatively in sheet moving systems and decurlers in printing machines and in other applications.
