Abstract
A belt conveyor comprising a conveyor belt having upper and lower inline rollers arranged in a stack and selectively actuated to rotate. When actuated, the upper article-supporting rollers are rotated by contact with the lower rollers riding on raised bearing faces in a carryway. When deactuated, the upper rollers are braked by braking pads and the lower rollers are out of contact with lowered bearing faces. The belt rollers are actuated and deactuated by a matrix of individually controllable roller actuation assemblies, each defining a roller actuation zone.
