  • Sheet registration device
    Patent number: 5269509
    Abstract: A cut sheet registration device comprises at least two idler rolls biassed into contact with an intermittently-driven feed roll, the idler rolls being pivoted on a bar which is itself pivotable with respect to the axis of the feed roll, so as to adjust the angle which the contact joints of the idler rolls make with the feed roll. The angle of the bar is adjustable at the factory to allow for any misalignment etc. in the downstream sheet-using devices.
