PRINTING AND FINISHING LINE Russian patent published in 1996 - IPC

FIELD: printing and finishing machines. SUBSTANCE: the line printing and finishing machine is made up of a number of printing sections of the "ribber-to-rubber" type; each section prints its own group of pages on paper cloth unrolled from the roll. Normal position of printing sections - with printing pressure off. At a passage through the section of paper cloth, where the respective group of pages should be located, printing pressure is switched on, and this group is printed. Each printing section is actuated by an individual torque motor, which is controlled by an electronic system. The necessity of drive of the printing sections from individual controlled motors is conditioned by the fact that at printing of an incomplete group of pages by one of the sections the cylinders of sections should be turned through a definite correction angle. In the folding and picking section the printed cloth is cut into strips, each having two longitudinal rows of pages. The strips are folded in two on folding forms, after which thin and narrow strips of glue located near their folds are applied onto them (every other). The glues are glued together and directed to the lateral cutting mechanism, where the pack of strips is cut into packs of single folded sections glued together by strips of glue near the spine folds. EFFECT: enhanced efficiency. 5 dwg
