A bookbinding system shapes a booklet in such a manner that a paper sheet bundle composed of plural text paper sheets is bound by case binding using a cover paper sheet. In this case, a paper sheet having a size fitting within a region configured with a front surface, a back surface, and a spine of the paper sheet bundle is used as the cover paper sheet. For example, vertically-long A4 paper sheets are used as the text paper sheets, and a horizontally-long A3 paper sheet is used as the cover paper sheet to carry out case bookbinding. The cover paper sheet does not protrude from the outer shape of the paper sheet bundle. Thus, it is not necessary to cut the cover paper sheet, and no cutting waste is generated.

Bookbinding apparatus adhesive applicator accurately, briefly controls adhesive temperature to a set value by selecting, in accordance with adhesive initial temperature, one of a plurality of temperature-controller heating modes defining different supply powers and supply durations for supplying power to an adhesive-container heater to control its heating temperature. A sensor detects the temperature of the adhesive in the container at applicator start-up, or on restarting a post-standby applicator. In accordance with the detected temperature, one of the heating modes is selected to heat the adhesive. The applicator warm-up time is thus set in response to the state of the adhesive: If solidified, the adhesive is heated and melted in a maximum supply-power, supply-duration mode; if low-temperature liquefied, it is heated and melted in a second-magnitude supply-power, supply-duration mode; and if the adhesive temperature is high, it is heated and melted in a minimal supply-power, supply-duration mode.

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.
