Abstract
A conveying device for collecting and transporting printed sheets has a first chain conveyor on which the printed sheets are placed astraddle to be conveyed in a conveying direction. A second chain conveyor is arranged downstream of the first chain conveyor in the conveying direction and synchronized with the first chain conveyor. An intermediate conveying device is arranged between the first and second chain conveyors and configured to grip intermediate products of collected printed sheets formed at the end of the collecting process on the first chain conveyor and to transport and transfer the intermediate products onto the second chain conveyor. The intermediate conveying device has a circulating traction mechanism and controllable grippers connected to the traction mechanism. The grippers grip a fold of the intermediate products lifted off the first chain conveyor and transport the intermediate products in an open position to the second chain conveyor.
