ABSTRACT:
A cable drive mechanism wherein a cable member comprising a plurality of individual cables disposed in side by side relation to form a flat member is successively wrapped around at least one cable wheel in one rotational direction and around at least one tension wheel in an opposite rotational direction, the tension wheel being mounted on pivot arms and connected to drive motors such that rotation of the tension wheel induces an angular moment in the pivot arms to urge the tension wheel toward the cable wheel in order to provide gripping friction on the cable member between the cable wheel and the tension wheel sufficient to overcome the inertia of the cable during start-up.
