Turning-bar-less folding machine of w-width rotary press

Abstract

A folding machine is composed of a mechanism for longitudinally dividing W-width travelling webs into two parts and overlaying one web on the other, the mechanism being mainly constituted by a former having the configuration of an inverted triangle with the base having a length equivalent to the W-width of a travelling web, and a slitter knife; a vertical pair of mechanisms for longitudinally folding the 1/2 W-width travelling webs into two parts which is mainly constituted by a pair of formers having the configuration of an inverted triangle with the base having a length equivalent to the 1/2 W-width of the travelling webs, the pair being veritcally disposed on the downstream side of the slitting and gathering mechanism at the same position with respect to the lateral direction of the travelling webs; a mechanism for cutting and folding the 1/4 W-width travelling webs in the lateral direction thereof; and a means for combining the route for the 1/2 W-width travelling webs which are discharged from the upper folding mechanism with the route of those which are discharged from the lower folding mechanism. The folding machine may be further provided with one or more color printed page rearranging means. Two folding machines may be combined with each other to deal with the printing of a newspaper having a great number of pages.
