A method for identifying signatures in a bookbinding machine is proposed. The method includes the steps of: providing (404-418) a representation of each signature of a predetermined sequence to be repeatedly processed by the bookbinding machine, for each cycle of the bookbinding machine involving the processing of a current signature, acquiring (404-405) a digital image of the current signature, comparing (420-424) the digital image of the current signature with the representation of an expected signature in the sequence, in response to a negative result of the comparison of the digital image of the current signature, comparing (448-458) the digital image of the current signature with the representation of at least one signature being adjacent to the expected signature in the sequence, and identifying (460) the current signature according to the results of the comparisons of the digital image of the current signature.

A solution is proposed for controlling a production of batches, each one of a corresponding bookbinding product, the bookbinding product including a group of bookbinding elements each one having a plurality of pages. For each batch, a corresponding control method (A1-A16) includes the steps of providing (A1-A2) printing information and processing information of the bookbinding product, the printing information including a digital image of each page of the bookbinding product, and the processing information including an indication of a composition of the bookbinding product in terms of the bookbinding elements and an indication of a composition of each bookbinding element in terms of the corresponding pages; in the solution according to an embodiment of the invention, the control method further includes determining (A7-A9) a representative digital image of each bookbinding element, the representative digital image of the bookbinding element being determined among the corresponding digital images according to the processing information, and recognizing (A10-A16) each one of a set of selected exemplars of the bookbinding elements by acquiring a current digital image of the selected exemplar and comparing the current digital image with at least part of the representative digital images.

A solution is proposed for recognising articles to be processed. A corresponding method (600) starts with the step of storing (603-639) an indication of an expected set of repetitive processing of the articles; each article of the expected set is defined by a code complaint with a predefined coding, an offset from a representation of the code on the article, and a frame of predefined size representing a portion of the article at said offset from the representation of the code. The method then provides for repeating (642-696) the following steps for each current article to be processed, corresponding to an expected article of the expected set (being defined by an expected code, an expected offset, and an expected frame). First of all, there is acquired (645) a current image representing at least part of the current article. The representation of a current code being complaint with this coding is searched (648-669) in the current image; a position in the current image of the representation of a corrupted code partially compliant with the coding is saved in response to a negative result of the search of the current code. In this case, a current frame of said size is extracted (681-684) from the current image at the expected offset from the position of the representation of the corrupted code. The current frame is compared (687-689) with the expected frame; a correctness of the article is determined (690) according to the comparison of the current frame with the expected frame.

A solution is proposed for controlling a bookbinding folding/sewing combined machine. A corresponding method (500) includes the steps of gathering (566) printed sheets in succession from a stack of sheets being supplied to the combined machine for obtaining groups of sheets, folding (572) the groups of sheets for obtaining corresponding signatures, and sewing (575) groups of signatures through continuous threads for obtaining corresponding book blocks. In the solution according to an embodiment of the invention, there arc further provided the steps of reading (509-521) configuration information from at least part of the sheets, causing (569-572) the folding of a current group of sheets to which a current sheet being just gathered has been added for obtaining a corresponding current signature in response to the reading of an end of signature indicator in the configuration information of the current sheet, and causing (578-581) the cutting of the threads of a current group of signatures to which the current signature has been sewn for obtaining a corresponding current book block in response to the reading of an end of book indicator in the configuration information of the current sheet.
