ABSTRACT:
A belt tensioning system for a belt transport particularly adapted for use in a document handling system of a reproducing machine. A belt is arranged for movement about first and second pulleys which are adjustably supported within a frame. The frame includes a tensioning system for adjusting the tension of the belt by changing the relative distance between the pulleys. The tensioning system includes a vernier for providing fine adjustment of the belt tension. The vernier system allows the belt tension to be adjusted while maintaining the parallelness of the belt pulleys.
