ABSTRACT:
A cutting and folding apparatus receives a printed web from a printing section including a plate cylinder and produces a variety of signatures. The apparatus includes a folding cylinder having a diameter two or more times as large as that of the plate cylinder, a collecting cylinder adjacent the folding cylinder and having a diameter 1.5 times as large as that of the plate cylinder, a pin cylinder adjacent the collecting cylinder and having the same diameter as the plate cylinder, and a gripping cylinder adjacent the folding cylinder and having the same diameter as the folding cylinder. To obtain superimposed signatures, cutting knives circumferentially provided on the folding cylinder transversely sever, in cooperation with holding members on the collecting cylinder, the running web supplied therebetween. The severed sheets are held by the holding members and superimposed one over the other, two superimposed sheets being successively transferred to the pin cylinder for delivery. For producing transversely folded signatures, cutting and holding members are provided on the folding cylinder and transversely sever the running web and holding the severed webs. Jaws on the gripping cylinder can cooperate with tucker blades for folding the severed webs carried by the folding cylinder.
