ABSTRACT:
A roller conveyor includes a belt of parallel free rollers interconnecting endless conveyor chains which move along a conveyor path. At least certain ones of the rollers carry encircling O-rings engageable with traction shoes for effecting rotation of the rollers. A given roller may carry more than one O-ring of different cross-sectional thicknesses, and the roller may be provided with recesses in which the O-rings are seated. The O-rings and traction means can be arranged in various configurations for effecting rotation of different groups of rollers, for effecting rotation in opposite directions, and for effecting rotation at varying speeds.
