ABSTRACT:
A flexible conveyor belt having layers of oppositely extending cord members which abut each other at the lateral centerline of the conveyor belt. The angle of the cord members in each successive layer may be opposed to that of the previous layer. The conveyor belt includes an elastomeric body having spaced apart edge portions and a top and bottom surface. An internal stretch limiter, such as an angularly woven fabric, is disposed in the central region of the belt along the lateral centerline of the belt. Because the angle of the cord members in each successive layer are opposed to each other, the belt is strengthened. Because the angled cord members abut each other along the lateral centerline, the sideways forces acting on the belt are negated. Because stretch limiting devices are provided along the lateral centerline, the belt may be pretensioned up to the limit of the elongation of the stretch limiter and remain under tension during use to enable the inner and outer edges to negotiate horizontal curves while retaining material thereon during the curves.
