A first press unit 2 presses each of a plurality of signatures S along a fold f, the signatures being supplied one at a time with the fold facing forward. The unit is arranged a signature conveyance unit 3 that conveys each signature received from, the first press unit while controlling the attitude to make the fold orthogonal to the conveyance direction. The unit is arranged a gluing unit 4 that applies glue to both lateral edges of a top surface of each signature received from the signature conveyance unit. The unit is arranged an accumulation unit 5 that sequentially stacks the signatures received from the gluing unit on one another while jogging the stacked signatures to form a book block B. The unit is arranged a second press unit 6 that discharges the book block received from the accumulation unit after pressing the same along the folds.

A process for the production of books (22) with digital printing from signatures, in which the book comprises signature groups (33), each formed with basic sheets (34), are parts of respective signature sheets (42). The process employs a manufacturing system (21) which includes a transversal cutting equipment (41) for cutting transversally the signatures sheets, and transversal and longitudinal folding equipment (46) for the formation of respective signatures (48). For a book with at least a sheet section devoid of text and/or figures in a last signature group, the method provides: a) identify a reduced signature group (59) including a number of sheet sections having at least a page with text and/or figures; b) cut the paper strip (23) to separate the reduced signature group as reduced signature group; c) actuate the transversal folding equipment (46) limited to the sheet sections having at least a page with text and/or figures and skipping the actuation of the transversal folding equipment (46) for a single sheet section; and d) actuate the longitudinal folding equipment (47) for folding longitudinally the reduced signature group.

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.

De-collatable bindings and methods of producing the same are disclosed. A disclosed includes a cover defining a spine and signatures disposed within the cover. The disclosed also includes a low tack adhesive disposed between the spine of the cover and the signatures to facilitate removal of the signatures from the cover.

A control unit of a paper processing apparatus controls a driving unit such that pressing by a pressing member is released after an end portion of a paper bundle pressed by the pressing member is cut by a cutting blade, and controls, when determining that a front end portion of a removal member does not reach the pressing member at a position of the pressing member in a state in which the pressing by the pressing member has been released, the driving unit to move the pressing member to a position at which the front end portion of the removal member reaches the pressing member after the paper bundle is taken out.

Provided is a saddle stitch folding apparatus including: a stitcher unit; a reel support unit configured to support a reel rotatably about the axis with a support shaft being inserted in a through-hole formed in the reel; and a rotation detecting mechanism configured to detect a rotation state of the reel, and the rotation detecting mechanism has an adhering member that is rotated while adhered to a bottom face of the reel, a rotating member having an insertion hole inserted in the support shaft, and a rotation detecting unit configured to detect the rotation state of the rotating member.

A method operates a facility, which serves for the continuous production of multiple gang runs for forming individual signatures or signature packs from which type-specific print products are made in a downstream print further processing machine. An endless web is the basis for the formation of these multiple gang runs. The endless web, in the non-folded state, is imparted complementary handling by facility-internal means according to the following criteria: i) in a 2-gang run, the individual signatures or the folded signature packs are only deflected in a second longitudinal air folding station disposed downstream of the first longitudinal air folding station; and ii) in a 3 or 4-gang run, the individual signatures or the folded signature packs are additionally folded in a second longitudinal air folding station disposed downstream of the first longitudinal air folding station.
