Abstract
A branching apparatus is provided in a paper-web threading apparatus of a rotary press in which, in order to thread a paper web into a threading path of the rotary press, threading guides are disposed at side portions of the threading path to extend therealong, thereby forming a threading-member traveling path through which a threading member can travel. The branching apparatus includes a branch threading guide in which a plurality of downstream threading-member traveling paths are formed such that they communicate with a single upstream threading-member traveling path via respective branching points, shifters disposed in the vicinity of the branch threading guide and having guide edges which operates at the branching points of the branch threading guide so as to guide the threading member to a selected downstream threading-member traveling path while closing the unselected downstream threading-member traveling path, and a drive for moving the shifter so as to selectively open and close the downstream threading-member traveling paths. It is possible to allow smooth traveling of the threading member. In addition, the branching apparatus can be simplified and be made compact.
