Abstract (en)
[origin: EP3315440A1] In the present invention, a web end (1 E), which is an end in the width direction perpendicular to the travel direction of a web (1), and a pattern end (1A1), which is an end in the width direction of each pattern (1A) repeatedly printed along the travel direction on the web (1), are detected at a first position in the web travel direction. A web end detection signal (G1) representative of the detected web end (1 E) and a picture end detection signal (G2) representative of the detected pattern end (1A1) are captured, and a control signal for aligning the pattern end (1A1) with a preset picture end reference position (P1) is generated. The web is moved in the width direction by the control signal.
