ABSTRACT:
A rotary roller band device having a central roller disposed within a cluster of orbiting rollers and rows of flexible bands holding the rollers together in a self-supporting structure. The bands are intertwined between the rollers such that as the rollers rotate the bands loop around and between the rollers. The bands engage each of the rollers in a low friction rolling contact that does not require lubrication. The bands each form a C-shaped loop. The central roller is cupped inside the C of each band loop such that the outer surface of each band contacts with the surface of the central roller. The orbiting rollers are concentrically arranged around the central roller and rotate counter to the central roller. Each of the orbiting rollers is disposed inside of the loop of each band such that the outer orbiting rollers engage the inner surface of each band.
