Abstract
At least three elongated flexible elements bonded together lengthwise to form constraint means arcuate in cross-section for forcing said elements to move in a predetermined path in which the flexible elements are bent longitudinally to form a loop of substantially uniform radius intermediate the ends thereof so that at least a portion of the loop is forced into a flat cross-section while the straight portions or trailing lengths of said elements on opposite sides of the loop are self-constrained in relatively stiff and straight runs whether either straight portion is pulled or pushed in relation to the loop, such that the flexible elements move as if reeved on a reel, sheave or the like.
