A plurality of different types (A, B, C) of components is fed to a production line or cell (L) by means of a conveyor for recirculating a plurality of pallets (P) on which said components (A, B, C) are carried. The conveyor comprises a horizontal carousel for recirculating the pallets (P) along an endless path. The conveyor is able to cause the pallets (P) to circulate in any of the two circulation directions, and the direction of circulation of the pallets is changed according to the type of component (A, B, C) required by the production line or cell (L) in each step of operation, in such a way as to carry a component of the type required to the production line or cell (L) in the shortest possible time. The conveyor (1) comprises a single chain-tensioning device (15) designed to tension the chain properly whenever the direction of movement of the chain is reversed. |
