ABSTRACT:
A conformable drive system for transporting a surface, such as an imaging surface, along a predetermined path of travel. An intermediate drive assembly, including an endless tape loop, operatively associated with a rotational drive source is provided. The endless tape loop is driven by the rotational drive source such that the tape loop, when positioned in frictional contact with the surface to be transported, induces transport movement of the surface. The tape loop includes a nonelastic support layer for preventing the tape loop from stretching, and also includes a frictional contact layer for providing substantial frictional forces between the tape loop and the surface being transported. The configuration of the conformable drive system provides sufficient contact pressure for imparting a substantially constant velocity vector to the transported surface for maintaining substantially constant speed control of the transported surface.
