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 After determining that a withdrawn cover securely matches the printed products of the following job, stopped printed products of the following job are released with a main control and fed into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.

Systems, apparatuses, and methods are provided for providing a rotatable perfect binding separated step solution configured to maximize efficiency for one-off book printing. The multi-clamp binding apparatus includes a rotatable body, a plurality of fixed operation stations associated with the rotatable body, and a plurality of clamps coupled to the rotatable body. Each of the clamps may retain at least one workpiece. The rotatable body may rotate each of the plurality of clamps to one or more of the plurality of fixed operation stations. In operation, a book block is received at an in-feed location of the perfect binding apparatus. The book block is stored within a holding apparatus of the perfect binding apparatus. The book block is then rotated between a plurality of fixed operation stations. At least one operation is performed upon the book block at each of the plurality of fixed operation stations.
