ABSTRACT:
A live roller conveyor includes a plurality of rollers arranged in a curved path with the axes of the rollers being located at an acute angle with respect to each other. A rotatable drive disc is located above the adjacent inner ends of the rollers, and an O-ring is mounted in a groove formed in the lower surface of the drive disc and engages the inner ends of the rollers. Rotation of the drive disc will be transmitted through the O-ring to the rollers to rotate the rollers about their axes. The vertical position of the drive disc relative to the rollers can be adjusted to provide precise control of the frictional engagement between the O-ring and the rollers.
