The invention concerns a device for separating imbricated flat products, in particular, folding boxes, with a delivery belt on which the products are supported in the form of an imbricated flow and are transported at a transport speed, with a transfer conveyor belt, disposed downstream of the delivery belt, which has a higher transport speed than the delivery belt. The transfer conveyor belt is designed as vacuum belt, or comprises a vacuum belt, and a retaining device is provided for the trailing flat products.
