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.

A production installation (21) produces book blocks (22) in parallel from digital prints on basic sheets (24). Each book block has n book sheets aligned through rows (46) and columns (44) and each basic sheet has m book sheets (43) equal to the number m of book blocks to be produced. Under the control of an electronic unit (56), a point bonding group (51) dispenses adhesive strokes (61) on the basic sheets across the rows and/or the columns, a stacking group (52) stacks the basic sheets and forms a basic block (62) stabilized by the point bonds, while a separation group (53) cuts and separates the book blocks from the basic block along the rows and the columns for following treatments. The basic sheets have machine-readable basic codes (68) and the electronic control unit actuates the point bonding group, the stacking group and the separation group on the basis of information derived from the basic codes.

An apparatus and a method for processing a digitally printed-on paper web, conveyed continuously through the apparatus includes a perforating tool for perforating the paper web transverse to its movement direction, and a cutting tool for cutting print sheets from a downstream end of the paper web. The tools are attached spaced-apart to a tool carrier which can be moved to two operating positions in which respectively one of the tools can be made to engage with a counter tool on a rotating cutting drum.

Provided is a lay-flat book block production apparatus. The apparatus comprises a glue dispenser, the glue dispenser to transition between an active state in which glue is to be provided to one side of the web which is to be guided past the glue dispenser and an inactive state in which glue is not to be provided to the web which is to be guided past the glue dispenser. The apparatus further comprises a folding unit, wherein the folding unit is to fold the web along a plurality of crease lines wherein each of a plurality of flat portions of a side of the folded web faces another of the plurality of flat portions of a same side.

A notebook is formed by folding up zigzag a continuous web form for every unit form with rouletted fold lines to form a text unit including a preset number of unit forms. After cutting off one folded side to leave the other folded side, the text unit is sandwiched between a front cover and a back cover and is covered with a spine. The spine is pressed against the remaining the other folded side of the text unit together with the front cover and the back cover by the medium of a mesh cloth impregnated with an adhesive so as to cover and wrap the whole a back of the stack of the front cover, the text unit and the back cover. The notebook can be used in a completely spread state (180-degree horizontal state) and conveniently, and retains high security and high functionality. A process for producing the notebook.
