ABSTRACT:
An endless power transmission belt and method of making same is provided wherein such belt is made primarily of an elastomeric material and the belt is a flexible, cool running, stress-relieved belt, wherein these characteristics are imparted to the belt by cooperating components thereof including a continuous fabric layer which defines the inside surface of the belt and the fabric layer has a plurality of folded portions extending into the compression section of such belt at spaced positions along the endless path of the belt. Each of the folded portions has associated portions of fabric in contact at an associated interface and the interfaces serve as stress-relief slits for the belt with the associated portions of fabric serving as fabric cushions on opposite sides of an associated stress-relief slit.
