Abstract: A conveyor system is disclosed having two independent conveyor belts which travel along the same path at various speeds. Each conveyor belt has at least one set of material handling platens attached thereto. Product is fed into the space between each pair of platens and is transported to a distal location where it is removed. A control mechanism operates the two conveyor belts such that product can be loaded into one set of platens at one speed, while product already loaded into another set of platens on the other conveyor belt can be transported and unloaded at a different rate.

Abstract: The invention is generally accomplished by providing a plurality of conveyors to which are attached material handling devices. For at least a portion of their travel the material handling devices each travel in the same track or path, although they are attached to separate conveyor mechanisms that travel parallel with each other. This allows the material handling devices attached to one belt to operate at one speed for loading of product and to stop or operate at a different speed for unloading but use the same loading and unloading stations. Each conveyor is independently driven and controlled and each of the parallel conveyors is provided with a series of material handling devices attached to a portion of the conveyor.
