An assembly device forming a basic machine for an assembly line which includes a plurality of conveyors; the plurality of conveyors including a first main conveyor (12), a secondary conveyor (13) extending in parallel relationship to the main conveyor (12) and two relatively spaced parallel lateral conveyors (14, 15) connecting ends of the secondary conveyor (13) to the main conveyor (12), the plurality of conveyors being disposed in a working plane, a second main conveyor (18) arranged in a return travel plane substantially coincident with the first main conveyor (12), two relatively spaced parallel lateral conveyors (19a, 19b) disposed in the return travel plane which are substantially coincident with the first-mentioned two lateral conveyors (14, 15) of the working plane, and transfer stations (20-27) at the points at which the plurality of conveyors meet at right angles.
