A method for the production of a print job by sequential or quasi-sequential digital printing includes forming at least one stack including signatures, print sheets and/or individual sheets produced by the digital printing. Components of the stack are transferred at least to a book-related printed product by means of at least one additional processing. The formation of the stack and the components thereof is carried out by means of production-related data or data sets which, by means of at least one workflow system, firstly select a specific sequence of individual book-related printed products made of the stack, and which secondly control a layout of the individual main printed products having same or different thicknesses and/or formats and/or having same or individual contents.

The invention is directed to a method for producing printed products, in particular softcover books, with integrated cover, where method includes at least the steps: printing of paper web or individually supplied paper sheets, preferably by means of digital printing; single or multiple folding and cutting of paper web to form signatures or else single or multiple folding of paper sheets to form signatures; stacking of signatures to form signature stack with at least one top and one bottom signature; folding open top sheet of top signature or else bottom sheet of bottom signature and applying an adhesive layer in at least area of folded-open sheet, which is intended to include at least spine and/or an area of signature stack adjacent to spine; and turning over sheet folded open and provided with adhesive layer around spine of signature stack, so that cover for printed product is formed.

This compact binding device is such that binding operations can be carried out when the main body of the device is held. The binding device (1A) is provided with a cassette storage unit (60A) in which a cassette (8) can be detachably attached, said cassette housing an elongate tape (5) which has a piece (2) adhered thereto and is wound into a roll. The cassette housing unit (60A) is provided at the bottom of the device main body (110A), which comprises a base unit (11A) and a handle unit (12), and the cassette (8) does not protrude rearwards from the handle unit (12) and the base unit (11A).

The device includes a first conveyor 1 and a second conveyor 12. The first conveyor transports the book blocks B to the bookbinding apparatus and can accumulate the book blocks on a transport surface 4. A first stopper 23 is arranged at an entrance of the second conveyor and a second stopper 28 is arranged in the middle of a path of book block on the transport surface of the first conveyor. The first and second stoppers can take a block position and a retracted position. The second conveyor and the first stopper operate in synchronization with an operation of the bookbinding apparatus. The second stopper takes the block position when the number of book blocks accumulated on upstream side of the first stopper exceeds a predetermined limit value, or when a thickness difference between the book blocks transported side by side exceeds a predetermined reference value.

A device for alignment of a book block consisting of single sheets and/or signatures is useable in a processing machine, in which manufacturing of books or printed products is carried out. The device is arranged upstream of a first processing station within the processing machine. The book block is feedable directly or indirectly into the device automatically or by hand. An alignment station has a base plate with a substantially vertically extending stop surface at an end thereof. The base plate has a movable part configured to carry out a movement with respect to the stop surface such that the movement of the movable part, in an operative connection to the stop surface, brings about an alignment of the single sheets and/or signatures at a book block edge, and such that, following alignment, the book block is grippable by at least one transport clamp for processing.

A binding method of a perfect-bound booklet includes the steps of folding each leaf of sheets forming a body to obtain multiple signatures; pressing creased parts of the multiple signatures in a thickness direction thereof; jogging a one-book bundle formed of a predetermined number of signatures forming a body, a front cover, and a back cover, or a multi-book bundle formed by stacking a plurality of one-book bundles on top of one another; applying a first adhesive that remains flexible upon curing, in a layer in a middle area 5 to 10 millimeters from both top and bottom ends of a rear face of the one-book bundle or the multi-book bundle; applying a second adhesive on the entire rear face; and drying and curing the second adhesive for a predetermined drying time.
