ABSTRACT:
Disclosed are conveyors and methods for making the conveyors. In one embodiment, a conveyor comprises a modular conveyor belt that includes a plurality of mat-top chains having a plurality of cavities and a plurality of first rollers disposed in the cavities of the mat-top chains. The conveyor further includes at least one second roller that operatively couples to the first rollers such that the first rollers rotate as the conveyor belt travels along the second roller. The invention can also be construed as providing the method for conveying objects. The method can comprise the steps of driving a modular conveyor belt in a direction of belt travel; rotating a plurality of first rollers disposed into the modular conveyor belt in a manner in which slippage of the first rollers is reduced; and conveying objects on the modular conveyor belt using the rotating first rollers.
