ABSTRACT:
A plastic conveyor belt formed of a large number of plastic belt modules includes outer belt modules having integral sideplates. The sideplates are of heavier material and higher strength, for withstanding stress around the outside of curves and for withstanding edge wear in certain types of conveyor systems. In a preferred embodiment, each sideplate has a depending guide member which may include a hold down tab. In one embodiment, plastic connecting rods which serially connect belt modules are discontinuous in length, made up of several coaxial pieces which are held in place by press fitting at the outer ends. This enables the rod to be of high shear strength in areas of high pulling force, e.g. at the outside of a radius conveyor belt in a curve, but of lower strength extruded construction elsewhere.
