Abstract: A high-speed digital printing system includes two unwinding machines for two input coils for a paper web, an input unwinding and splicing installation and a printing station and in which the input installation supplies, in turn, the printing station with the web of the two coils. The system also includes a splicing and rewinding installation with an output cutting and splicing equipment for an incoming web emerging from the printing station and two rewinding machines with two output coils. The output equipment feeds alternatively the rewinding machines with the incoming web by cutting and splicing of a web of the two output coils without stopping printing. An electronic controller switches the functionality of the output cutting and splicing equipment and of the rewinding machines with setting of the output coils as an operating coil and a waiting coil and, viceversa, as a waiting coil and an operating coil.

Abstract: Cutting equipment (41) which processes overlapped continuous forms (23H, 23L) is disclosed. The cutting is carried out by means of a cutting device (29), which separates the sheets from the forms, introduction devices (28H and 28L), which enter the continuous forms (23H, 23L) into the cutting device and a singularizing device (46) for overlapped sheets, which includes two transport paths (81 and 82), the one above the other, with differentiable transfer times; the singularizing device comprises a diverter (83) upstream of the transport paths (81 and 82); the introduction devices (28H and 28L) are actuatable for temporarily projecting a leading edge of one of the overlapped forms (23H, 23L) with respect to the other form up to a switching zone of the diverter (83), or for advancing together the overlapped forms (23H, 23L); the diverter (83) is configurable for addressing a continuous form or both forms (23H, 23L) to one or to both transport paths (81 and 82); and the introduction devices (28H and 28L) are also actuatable, in the case of projecting of one of the continuous forms, for lining up trailing edges of the sheets of the one and the other form for a joint cutting of the overlapped forms (23H, 23L) by means of the cutting device (29).

Abstract: Separator cutter for printed sheets from a continuous paper web provides multiple longitudinal divisions of different working sections with a series of single or adjacent sheets. The sheets have respective print areas with texts and/or images, while the cutter includes margining knives and longitudinal dividing knives and an electronic control unit. The cutter operates with webs wherein, at the beginning of each working section, a printed image mark (Print mark) is placed at a distance of the print area and automatically sets margins and division cuts based on a corresponding working section. The cutter includes servo mechanisms for displacement of the margining and longitudinal dividing knives and a sensor for the Print mark. In response to a new working section, the servo mechanisms is activated by positioning the knives in transverse positions based on data from the new working section and referencing the transverse position of the Print mark.

Abstract: An equipment of accumulation of sheets forms a stack of sheets on an accumulation plane by means of driving belts and diverters arranged along the path of the sheets and jump on the accumulation plane. The height of the jump is modified by shifting vertically the accumulation plane with respect to the diverters according to number and/or thickness of the sheets. The diverters can be shifted according to the length of the sheets to be accumulated, while a series of arrest lugs delimits at the rear the area of collection of the sheets and a forwarding mechanism with a pair of output rollers forwards the stack of accumulated sheets when the lugs are released.

Abstract: A cutting equipment trims strips of webs in movement by means of a stationary trimming blade and a rotating cylinder with a mobile trimming blade during transversal cuts and separation of basic sheets. The rotating cylinder includes a sector with suction openings connected to a vacuum source, which retains the strips by suction and drags the strips up to a collector of the trimmed strips. The cutting equipment cuts and separates transversal strips of two webs overlapped in adherence jointly to the cutting of the basic sheets. To this end, a perforating device perforates a row of holes on the first web adjacent to an edge of the sheets: a first web is positioned with the row of holes in front of the suction openings, while the strip of the second web is retained and dragged by suction through the holes of the first web up to the collector of the trimmed strips.

Abstract: 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.
