Abstract
A belt conveyor with dual upper runs and dual lower runs defined by a single continuous belt for synchronized movement of the upper runs. The dual lower runs cross each other and are guided by longitudinally spaced support rollers which twist the lower belt runs and vertically shift at least one of these lower runs to provide for free unencumbered crossing of the lower belt runs and the keepers mounted on the belt to assist in movement of material.
