Abstract
A tape-type mechanical drive including a flexible but substantially inextensible tape connected between two elements so that the tape transmits forces in tension. The tape includes a plurality of plies, disposed in two runs, and an equalizing device is provided for maintaining the plies under equal tension as the curvature of the tape changes. The plies in each run remain substantially parallel to one another. The tape may be formed from a single continuous strap folded to define a plurality of spiral turns.
