A method for production of adhesive-bound printed products in a machine belonging to an adhesive-binder line. To change over from one job under production to a following job, supplied printed products of the following job are detected via a barcode and stopped prior to being fed into the machine of the adhesive-binder line. Remaining printed products of a preceding job are moved and fully processed through individual processing stations of the machine while the printed products of the following job remain in a waiting position in front of the machine. After completing the last printed product of the preceding job, an empty withdrawal of covers stored in a cover deposit and belonging to the following job is initiated until it is ensured that the stored covers are available for the printed products of the following job. After determining that a withdrawn cover securely matches the printed products of the following job, stopped printed products of the following job are released with a main control and fed into the machine for being processed via the individual processing stations.

Disclosed are various embodiments relating to verifying a printed work comprises a correct number of pages. Associated with a stack comprising one or more pages is an identifier that may be used to obtain an expected value for a physical characteristic of the pages in the stack. A sensor may then measure an actual value for the physical characteristic of the pages in the stack. Before binding the pages in the stack, the expected value may be compared to the actual value in order to verify the stack comprises the correct number of pages.

Systems and methods are provided for automatically correcting book portion mismatches in a book binding operation. First sensor outputs relate to a first book portion sequence along a first assembly channel, and second book portion sequence along a second assembly channel, each leading into a book binding stage. A mismatch state between first and second book portions is predicted based on the respective sequences and a defined book assembly batch, responsive to which an intervention event is selected and executed. One such intervention event includes selective routing of the first and/or second book portion associated with predicted mismatch states into a correction channel and reinsertion of the first and/or second book portion into the respective assembly channel corresponding to a modified version of the respective sequence. In some embodiments, a further sensor may be provided at the book binding stage entry for further confirmation/control feedback regarding matched book portions.

A production plant (22) for books (23) printed with digital technologies, comprising one or more forming stations (26) of book blocks (32), one or more cover binding machines (27) for assembling the book blocks with respective covers (33), an electronic center (29) and a plurality of spiral towers (39) for accommodating the book blocks of the forming stations and transfer them to the binding machines. The book blocks and the covers have respective book codes (34) and cover codes (36) uniquely associated with the respective books of a given working order. Each tower (39) includes a conveyor belt (42) that can be moved along a spiral path, a belt motorization group and an electronic control unit (44). The towers serve as a temporary storage for the blocks and capacity of movement between loading areas (49) adjacent to the forming station and unloading areas (50) adjacent to the binding machines. The electronic control units (44) pre-set the towers to store in an optimized way along the conveyor belt the book blocks from the forming stations, to supply the binding machines with the stored book blocks and to form and memorize databases identifying the stored book blocks. The electronic center (29) of the plant is interfaced with the electronic control units (44) of the towers and with the binding machines for a survey of the loading data and for a functional coupling of the loaded towers with the binding machines.
