The Invention is based on the idea of a flexible system or method for producing bound paper products or book blocks to provide, as a transport dolly, in particular Self-propelled trolley, are provided, each one appropriate recording for sheet pile and sheets or interleaf sheets as well as bottom sheets and cover sheets exhibit. In addition, the, preferably self-propelled, Dolly via a suitable means of identification, For example, an RFID identification means or RFID tag and appropriate distance sensors to the distances between to detect the trolley and predetermined distances to keep between the trolleys.

Overall, a flexible book block gathering system is provided, which in particular comprises a multi-use stack removal device or a multi-purpose sheet stack delivery device and moreover comprising various bottom sheet, intermediate sheet and cover sheet feeding devices and a discharge station on a further processing machine. In this case, the sheet stack delivery device and the application devices and the further processing machine by a rail transport system, in particular a monorail transport system, connected to each other.

According to the Invention are in a sheet stack dispenser a plurality of sheet stacks, in particular at the same time, each in a receptacle of several transport vehicles inserted or handed over, so that a counted Paper layer is inserted in the receptacles respectively. Especially is already in the shots of the trolley already a bottom sheet before the first sheet pile in the recording present previously from a bottom sheet feeder in the appropriate recording of the transport direction inserted or created has been.

After that drive the trolleys from the sheet stack dispenser the subsequent application devices, so that a predetermined intermediate sheet on the previously introduced paper layers or the introduced stack of sheets with a predetermined number of paper layers on the paper machines is placed. This creates a paper intermediate, wherein the trolley via a loop to the sheet stack dispenser retracts when in the receiving of the transport carriage no complete, unbound paper intermediate is available. Accordingly, the transport slide through several times a (closed) loop on the sheet pile delivery apparatuses, until a complete paper intermediate with a predetermined Number of paper layers and intermediate sheets arranged between them and a bottom sheet and a cover sheet in the receptacle of the transport carriage is.
