An intermediate storage including an intake station and an output station, two vertical conveyors, and two horizontal conveyors forming a conveying circuit with the two vertical conveyors. All conveyors are in a form of chain conveyors. The two vertical conveyors each include chains including catches and are arranged in pairs, each with an individual chain drive. Level differences which occur in operation between transferring edgers of unit load suppliers and carrier plates can be identified and corrected immediately. To keep a mutual gap between successive gondolas small, the gondola of a gondola pair that is running ahead is deflected sideways in the region of the deflection. A collision with the following gondola is thus reliably avoided.
