Abstract
A conveyor system utilizing a plurality of modular links mounted by a plurality of transverse cross rods that retain the links together, forming the conveyor belt. The modular links include a plurality of apex portions, a plurality of leg portions extending therefrom and a plurality of foot portions. The apex portions include an elongated slot receiving the cross rod to allow longitudinal freedom of movement to the conveyor belt. The modular links further include side link portions that are adapted to engage conveyor guide rails integral with a support frame. Each side link portion is formed by including a depending arm having a transversely extending tab. A locking tab including resilient prongs is placed within a corresponding slot in each side link to retain the cross rod. Side rails attached to side rail brackets are provided adjacent the peripheral edges of the conveyor belt to maintain the transported product on the conveyor belt. The side rail brackets include a horizontally extending leg passing through a cross bar that supports the attached guide rails. The bore of the cross bar has grooved side surfaces to mate with ridged surfaces included on the horizontal leg of the si…
