PURPOSE: To cut a thick printed sheet without damage even in the case of a high manufacturing speed, by arranging the cutting drum of a two-times drum so that the cutting drum can be actuated to the corresponding cutting thread piece drum of a five-times drum to make both the drums cooperative, and attaching the folding drum of a three-times drum to a corresponding cutting thread piece drum. CONSTITUTION: The high cutting force of a cutting drum 14 can be received without fatigue, by using a solid corresponding cutting thread piece drum 1 or a collecting drum as a corresponding cutting drum. High centrifugal force, in its turn soil due to the rub of a printed sheet, can be avoided even in the case of folding operation based on the large whole periphery of the drum 1. The action and switch of a stitching device 36 to a folding drum 18 can be possible by constituting a folding drum 18 equipped with a folding blade carrier 23 having a rotating axis 28 positioned outside the rotation center of a folding drum. Consequently the temporary stitching of a printed sheet before folding can be made in a tabloid form in particular. |
