Abstract
A support for a flat conveyor belt is disclosed which utilizes a pair of tapered rollers, one on each side of the belt's centerline. The rollers are mounted on shafts which are inclined to the plane of the belt such that the roller surfaces are parallel to the surface of the belt. The roller supporting shafts are also at an angle of less than 90.degree. to the centerline of the belt such that they converge either upstream or downstream of the belt with respect to the belt's direction of travel. The rollers are also free for a limited degree of travel in response to the bias given to them by the movement of the belt. The angular relationship of the shafts to the belt centerline can be varied resulting in lateral movement of the rollers. This results in vertical movement of the belt and thus a conveyor with the capacity to serve as an accumulator.
