International ClassB65G 021/14AbstractA powdered, flexible, expandable conveyor comprises a pair of flexible, expandable link assemblies, preferably in the form of a plurality of links pivotally connected to each other in an X-shaped chain. The conveyor surface preferably includes a plurality of individually powered rollers. The individually powered rollers are mounted between the link assemblies at spaced locations along the length of the conveyor. Each of the powered rollers is rotatably driven by a motor housed inside the roller together with an individual gear box. Each motor is electrically connected to a terminal block located outside the powered roller which in turn is connected to a power supply. The gear boxes individually associated with the various motors may have different gear ratios in order to accommodate different loading. The conveyor is sufficiently flexible to be able to form a curved conveyor surface.Other References
