A process for the production of books (22) with digital printing on a continuous paper strip (23), in which the strip defines book sections in sequence, with signature groups (33), each formed with basic sheets (34); the process employs a manufacturing system (21) which includes a transversal cutting equipment (41) for separating signature groups (33) as 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 process for the production of books with digital printing on a continuous paper strip, wherein said paper strip defines a longitudinal axis and book sections in sequence along said longitudinal axis, each book section is associated to a book and includes a number of signature groups, and each signature group is formed with a given number of basic sheets of the book, and wherein said process employs a system for manufacturing books comprising a transversal cutting equipment for cutting the paper strip transversally to the longitudinal axis in order to separate the signature groups as signature sheets, a transversal folding equipment for folding transversally the signature sheets with respect to the longitudinal axis, and a longitudinal folding equipment, for folding longitudinally signature sheets transversally folded in order to form respective signatures preparatory to a basic book block, said process comprising the following steps:
A system for manufacturing books printed on a paper strip, comprising a perforating equipment for longitudinal and transversal perforations of the paper strip, a transversal cutting equipment, a transversal folding equipment, a longitudinal folding equipment and a stacking device, in which said paper strip has book sections in sequence arranged as signature groups, and in which each book section includes a number of signature groups and each signature group is formed with a given number of basic sheets and the transversal cutting equipment is actuatable for separating the signature groups as signature sheets, while the transversal folding equipment and the longitudinal folding equipment are actuatable for transversal and longitudinal folds of the signature sheets, said system further comprising a program such to:
A book produced by a system for manufacturing books with print on both the sides of a paper strip and book sections of the paper strip in sequence, organized as signature groups, and in which said system comprises a transversal cutting equipment for separating the signature groups as signature sheets, a transversal folding equipment and a longitudinal folding equipment for transversal and longitudinal folds of the signature sheets, wherein said signature groups include sheet sections, which are formed by side by side basic sheets and are separable from the paper strip through a single cut, and wherein said book comprises a number of signatures each one formed with a given number of basic sheets and a signature with a reduced number of sheets when the part of the book sections regarding the last signature has at least a sheet section without pages with text and/or figures.
