ABSTRACT:
A stretchable U-shaped conveyor belt with reinforcing members extending transversely of the belt and spaced apart longitudinally of the belt. Elastic stretchable material between the reinforcing members permits prestretching the belt so that the edges remain in tension when the belt passes around curves and thereby maintains the molded shape of the belt in horizontal and vertical curves. The conveyor belt is driven by a power belt and guided by guide rollers. The power belt and conveyor belt are carried by support rollers mounted on frames at spaced-apart positions along the belt path. The frames are fastened to a resilient, flexible spine member which provides for positioning of the frames around vertical and horizontal curves. The U-shaped cross section of the belt is also maintained by U-shaped reinforcing members of high modulus material which are positioned in two spaced layers within the molded body of the belt. Layers of cords of low modulus textile material between the reinforcing members provide resistance to tearing and strengthen the belt for holding fasteners as well as increase the effectiveness of the U-shaped reinforcing members.
