In transporting sheets of paper it is useful to be able to accurately position them in the direction of travel. Reg-istration, as this is called, may be accomplished either against a moving barrier if the sheet is to subsequently be carried elsewhere, or against a fixed barrier if the stream of sheets is to be assembled into a stack. In either case, over-driving the sheet enough to get reliable registration tends to buckle the sheet.
