  • Counter-clockwise single sheet rotator
    Patent number: 5145168
    Abstract: A pivot brake is used in conjunction with a ball-on-belt transport and dual registration edge guides to rotate and register the output of printers by 90.degree. to satisfy on-line finishing requirements. As a sheet is fed into the rotation mechanism by the ball-on-belt transport, it encounters the pivot brake which retards its travel. The ball-on-belt transport continues to drive the sheet, thereby rotating it about the brake and into the registration edge guides.
