Title:
ROLL-TO-ROLL PRINTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/088407
Kind Code:
A1
Abstract:
In order to provide the ability to finely control the tension of a base material, a roll-to-roll printing apparatus that performs seamless printing on a base material using a roll-to-roll system is provided with: a driving roll (74) that supplies a base material (B) to a plate cylinder; a driving roll actuator that rotates the driving roll (74); a dancer actuator (84) that changes a pass line length of the base material (B) to change the tension of the base material (B); a tension detection device (78) that detects the tension of the base material (B); and a tension control device (80) that controls the driving roll actuator and the dancer actuator (84) according to a detection result from the tension detection device (78) and compensates for a tension fluctuation of the base material (B). When compensating for the tension fluctuation of the base material (B), the tension control device (80) performs relatively rough control with the driving roll actuator and relatively fine control with the dancer actuator (84).
