A scrollerwheel is a mechanical device composed of a number of rollers (four or more) and connective bands under tension, which wrap around and weave between the rollers forming a self-supporting cluster possessing a central roller. The cluster of rollers is bound by the connective bands in such a way that the static friction between the rollers and bands prevent the rollers from slipping as they roll and orbit the central roller.
