  • Patent number: 5623720
    Abstract: Disclosed is a novel method and apparatus for rotating a stripper bar associated with a paper path. A cam and cable mechanism replaces a rigid link mechanism on the stripper bar, the cam and cable mechanism providing for a much greater angle of rotation of the stripper bar than the rigid link mechanism. The additional rotation allows the stripper fingers on the stripper bar to be rotated completely out of the way of a paper jam clearance path. Other new developments include a wrench positioning system that controls the orientation of the stripper bar and an over-rotation prevention system that stops the rotation of the stripper bar when the stripper bar and stripper fingers are being serviced.
