Drive means may comprise a chain 16 attached to the radially outer edge Or the belt and a drive sprocket 30, the chain being constrained to maintain its curved path to prevent the belt moving radially inwardly. The diameter of the end deflection rollers is independent of the curvature or width of the conveyor path.
