Patent ID: 10618271

Abstract:
In order to provide a numbering and imprinting machine capable of minimizing the amount of wasted paper produced, the numbering and imprinting machine is provided with: a first-number inspection camera (124B) that is arranged downstream of the position of contact between an impression cylinder (112) and a first-number cylinder (113) of a first-number printing unit (111) in the direction of rotation of the impression cylinder (112), and images a first number printed on paper (W) held on the impression cylinder (112); a second number inspection camera (124C) that is arranged downstream of the position of contact between an impression cylinder (117) and a second-number cylinder (118) of a second-number printing unit (116) in the direction of rotation of the impression cylinder (117), and images a second number printed on paper (W) held on the impression cylinder (117); and a printing-press control device (10) that controls first- and second-number-cylinder throw-on and throw-off devices (38, 39) based on signals from the first- and second-number inspection cameras (124B, 124C) to cause the first-number cylinder (113) and the second-number cylinder (118) to make separating movements.
