Patent number: 11148412Abstract: In order to provide, to a roll-to-roll printing apparatus which seamlessly performs printing on a base material using a roll-to-roll method, performance for finely controlling the tension of the base material, the roll-to-roll printing apparatus includes a drive roll (74) that supplies a base material (B) to a plate cylinder, a drive roll actuator that rotates the drive roll (74), a dancer actuator (84) that changes a path line length of the base material (B) to vary 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 drive roll actuator and the dancer actuator (84) in accordance with a result of the detection by the tension detection device (78) to compensate for a variation in the tension of the base material (B).Type: GrantFiled: November 7, 2017Date of Patent: October 19, 2021Assignees: ASAHI KASEI KABUSHIKI KAISHA, SUMITOMO HEAVY INDUSTRIES, LTD.Inventors: Keita Suzuki, Shinya Matsubara, Taishi Hitomi, Makoto Ikeda, Kiyoto Miyoshi, Takatora Ando
