Date Aug. 28, 1986.In belt conveyors having two parallel belts (1) with feeders, movement of the belts must be synchronized. The known method of achieving this is by means of electrical systems. The present invention entails a radical simplification of this synchronization by using a single belt (1) crossing over below the conveyor, the two parallel sections on the upper side of the conveyor thus moving snychronously. The conveyor according to the invention is less expensive and more reliable than previously known conveyors, nor is it dependent on a source of electric power. |
