<p>A conveyor belt (20), particularly suited to the food processing industry, includes a tension-bearing framework of transversely extending rods (36-38, 141, 168, 172, 177) connected to tension-bearing interconnected links (45) into which is attached a series of loose-fitting modular product support members (23-25, 134, 138). The product support modules include forwardly and rearwardly extending link ends (27, 30) such that successive modules are interfitted with one another. Each of the forwardly and rearwardly extending link ends are provided with slotted longitudinal openings (76, 77, 82) through which the transverse rods extend. The distance between a front wall portion defining the slot in a forwardly extending link end and a rear wall portion defining the slot in an associated rearwardly extending link end is greater than the fixed longitudinal spacing spanned by adjacent transverse rods so as to permit some relative longitudinal movement between the conveyor modules and the rods. In addition, at least one of the modules and the rods are provided with standoff elemnents (84, 136, 143, 170, 174, 179) which define a minimum contact area between the modules and the rods. This limited contact area creates larger openings between the conveyor modules and the rods such that when the conveyor belt is passed through a washing unit (15), washing sprays can effectively reach all surfaces. In addition, since the conveyor modules are permitted to shift longitudinally relative to the rods, this further enhances the elimination of debris trapping zones such that a highly sanitary conveyor belt arrangement is obtained. In addition, unique end cap members (47) are provided to prevent relative rotation between drive links associated with the conveyor belt and the transverse rods.</p> |
