A method for controlling a combined bookbinding machine, the method comprising the steps of: reading configuration information associated at least in part with a basic signature being ready in each one of a plurality of feeding stations (110f,110p) of the combined bookbinding machine comprising at least one folding feeding station and at least one opening feeding station, the configuration information comprising a progressive number of basic signature indicative of a position of the basic signature within a group of one or more basic signatures provided by the feeding station for a corresponding overlapped signature comprising the groups of basic signatures provided by the feeding stations being overlapped one to another, selecting (642,645,660) at least one of the feeding stations whose basic signature has the progressive number of basic signature not indicative of a first basic signature of the corresponding group or whose basic signature has the progressive number of basic signature indicative of the first basic signature and the basic signature of each one of all the other feeding stations has the progressive number of basic signature indicative of the first basic signature of the corresponding group, depositing the basic signature from each selected feeding station astride a transport saddle of the combined bookbinding machine to contribute to the formation of the corresponding overlapped signature on the transport saddle and obtaining a next basic signature in the selected feeding station, transporting each overlapped signature towards a binding station of the combined bookbinding machine to contribute to the formation of a corresponding book block, comprising a plurality of overlapped signatures being bound one to another, in response to the reading of an indicator of end of overlapped signature in the configuration information, and completing the binding of the book block in the binding station in response to the reading of an indicator of end of block in the configuration information of at least one the corresponding basic signatures. reading configuration information associated at least in part with a basic signature being ready in each one of a plurality of feeding stations (110f,110p) of the combined bookbinding machine comprising at least one folding feeding station and at least one opening feeding station, the configuration information comprising a progressive number of basic signature indicative of a position of the basic signature within a group of one or more basic signatures provided by the feeding station for a corresponding overlapped signature comprising the groups of basic signatures provided by the feeding stations being overlapped one to another, selecting (642,645,660) at least one of the feeding stations whose basic signature has the progressive number of basic signature not indicative of a first basic signature of the corresponding group or whose basic signature has the progressive number of basic signature indicative of the first basic signature and the basic signature of each one of all the other feeding stations has the progressive number of basic signature indicative of the first basic signature of the corresponding group, depositing the basic signature from each selected feeding station astride a transport saddle of the combined bookbinding machine to contribute to the formation of the corresponding overlapped signature on the transport saddle and obtaining a next basic signature in the selected feeding station, transporting each overlapped signature towards a binding station of the combined bookbinding machine to contribute to the formation of a corresponding book block, comprising a plurality of overlapped signatures being bound one to another, in response to the reading of an indicator of end of overlapped signature in the configuration information, and completing the binding of the book block in the binding station in response to the reading of an indicator of end of block in the configuration information of at least one the corresponding basic signatures.
