ABSTRACT:
An elevator load bearing assembly (20) includes a plurality of cords (22) within a jacket (24). The jacket has a plurality of grooves (32, 34, 36, 38 40) spaced along the length of the belt assembly. Each groove has a plurality of portions (50, 52, 54, 56) aligned at an oblique angle (A, B) relative to a longitudinal axis (48) of the belt (20). In one example, the grooves are separated such that there is no longitudinal overlap between adjacent grooves. In another example, transitions (60, 64) between the obliquely aligned portions are at different longitudinal positions on the belt. Another example includes a combination of the different longitudinal positions and the non-overlapping groove placement.
