The invention concerns an accumulator device having a general U-shape consisting of two parallel endless belt conveyors, communicating through an endless belt conveyor with semicircular trajectory borne by a mobile carriage driven by a translation movement parallel to said parallel conveyors. The invention is characterised in that said accumulator device comprises means for guiding (20, 21, 22, 23) the upper side of the endless belt (5) of the first conveyor (4) adapted to lower the downstream part of said upper side located beneath the semicircular conveyor (10) which does not serve as transport plane for the products, said lowering enabling to place in the same plane, the transport plane of said first conveyor (5) and the transport plane of said semicircular conveyor (10), said guiding means (20, 21, 22, 23) being simultaneously mobile with the carriage (16) for manoeuvring in translation said semicircular conveyor (10) so that the downstream end of the transport plane of said first conveyor (5) should follow the displacement of the upstream end of said semicircular conveyor (10).
