Folding apparatus of rotary press

摘要

A folding apparatus of a rotary press which can select collect run or straight run comprises: a fixed pin cam 2 which performs operations of straight run and collect run; a correction pin cam 3 which stops in case of straight run, and protrudes/retracts a pin end portion with respect to an outer periphery of a folding cylinder once per two rotations of a folding cylinder 12 in case of collect run; a blade cam 4 which thrusts a blade of each blade device 16 into a jaw device 17 once per rotation of the folding cylinder in case of straight run, and thrusts the same into the jaw device 17 once per two rotations of the folding cylinder in case of collect run; switching means 62 for switching between a drive side connection and a stop side connection of the correction pin cam and the blade cam; and detecting means 61 for detecting a start-up timing of the switching means.
