ABSTRACT:
A registration mechanism for offsetting paper sets against a registration edge which is alternately in an inboard and an outboard position. The paper sheet is urged against the registration edge by means of two rotating urathane paddle wheels positioned relatively closely to the registration edge, but the sheet is prevented from generating too much angular velocity by two restraining means in the form of TEFLON balls held in retainers which prevent the balls from moving laterally but allow the balls to move vertically and rotationally, these restraining means located relatively further away from the registration edge. Because the mechanism is operating in the absence of a sheet of paper most of the time, a freely spinning roller is provided in a space in the base plate under each wheel which normally is driven by the wheel in the absence of a sheet of paper at a speed sychronous to that of the wheel, thereby lessening the wear on the wheel.
