Abstract
A multi-section folding apparatus has two outer formers which are respectively provided on both sides of a pair of inner formers which are defined by a pair of upper and/or lower formers of a vertical two-stage former folding machine in such a manner that the outer formers are positioned at the same level as that of the inner formers and with a slight spacing provided therebetween, thereby forming a quadruple former assembly. Two groups of turn bar mechanisms are disposed in such a manner that the course of each of the halved traveling sheets which are obtained by halving a traveling sheet and which are fed toward the two inner formers along their respective ones of the four travel lanes is changed to any one of the other three travel lanes. It is therefore possible to issue a newspaper made up of six to eight sections by means of straight folding without lowering the production speed. In addition, it is possible, by virtue of the turn bar mechanisms, to issue a newspaper made up of an odd-number section in addition to an even-number section, and also to set as desired the number of pages of each of the sections constituting a newspaper.
