Infeed system of rotary press

Abstract

In a rotary press, a traveling amount of a paper web is controlled by an infeed system including infeed rolls which feed the paper web to a subsequent stage for an operation such as a printing process. The infeed system of the rotary press includes a traveling amount measuring device disposed on a traveling line of the paper web fed by the infeed rolls for measuring the traveling amount of the paper web in a tension free state and for generating a signal representing the measured result, and a traveling amount controlling device for controlling the traveling amount of the paper web fed by the infeed rolls in response to the signal from the traveling amount measuring device.
