Abstract A backup station in a carton filling machine for the delivery and packaging of premanufactured blanks into transport containers. The station is arranged between an imbrication station and a delivery belt which includes a rotation station. Within the backup station, a support rail is arranged in the direction of delivery of the blanks which provides support for the blanks. Two conveyor belts running along the support rail are raised above the surface of the support rail during normal operation and are lowered by the backed-up blanks during backed-up operation.
