Process and system for the production of books with digital printing from a continuous paper strip and respective book

Abstract

A process for the production of books () with digital printing on a continuous paper strip (), in which the strip defines book sections in sequence, with signature groups (), each formed with basic sheets (); the process employs a manufacturing system () which includes a transversal cutting equipment () for separating signature groups () as signatures sheets, and transversal and longitudinal folding equipment () for the formation of respective signatures (); 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 () including a number of sheet sections having at least a page with text and/or figures; b) cut the paper strip () to separate the reduced signature group as reduced signature group; c) actuate the transversal folding equipment () limited to the sheet sections having at least a page with text and/or figures and skipping the actuation of the transversal folding equipment () for a single sheet section; and d) actuate the longitudinal folding equipment () for folding longitudinally the reduced signature group.
