Abstract
A wiper mechanism for lateral shifting of a sheet against a side guide defining a registered reference position. The mechanism includes an oscillated wiper arm under the sheet having an arcuate sheet-engaging wiper surface with a tap roller for pressing the sheet against the wiper surface during the outward movement of the arm. The wiper surface has axially adjacent strips surfaced for different amounts of friction. The roller has an effective width corresponding to the width of one of the strips and is movable into a position of engagement with a selected strip for changing the degree of friction applied to the sheet depending upon the thickness of the sheet being handled.
