Abstract
A modular conveyor belt with sturdy edges capable of supporting the weight of the belt along a carryway. The sturdy edges have bearing surfaces, such as the peripheries of wheels or the faces of wear pads, mounted at the sides of the belt to bear the belt's weight when the belt rollers are not supported on a roller-activation system.
