A belt assembly for a belt turn conveyor includes a belt with a plurality of longitudinal fibers generally aligned or oriented along the curved longitudinal axis of the belt. The belt may comprise a plurality of belt segments which are interconnected to form an endless belt, with each belt segment preferably including a plurality of longitudinal fibers aligned along the longitudinal axis of each respective belt segment. When interconnected, the longitudinal fibers of each belt segment generally align along the curved longitudinal axis of the belt. Alternately, the belt may be woven such that the longitudinal fibers are substantially aligned along the curved longitudinal axis of the curved belt. Thus, a belt assembly for a belt turn conveyor is provided that exhibits a more uniform stiffness along its length, which results in the belt assembly exhibiting reduced forces across its length thus increasing the belt's capacity and longevity.
