A materials handling device comprising a cascade of vibrating conveyors (61, 71, 81), each upstream conveyor (61, 71) being nestable in a downstream neighbour (71, 81) with clearance, and movable relative thereto from a nested condition in which product is conveyed from one conveyor to another, to a separated position in which product falls from the first conveyor into a gap between the adjacent conveyors. The invention avoids mechanical gates which are noisy, unreliable and are liable to trap the product being conveyed. <IMAGE> |
