An accumulator having a general U-shape includes 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 the parallel conveyors. The accumulator 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 the upper side located beneath the semicircular conveyor (10). The lowering places in the same plane, the transport plane of the first conveyor (5) and the transport plane of the semicircular conveyor (10). The guide is simultaneously mobile with the carriage (16) for manoeuvring in translation the semicircular conveyor (10) so that the downstream end of the transport plane of the first conveyor (5) should follow the displacement of the upstream end of the semicircular conveyor (10). |
