Abstract (en)

The method involves placing each new roll (14) on a support tray (22) before sliding between support arms to fit into the printing press. The lateral alignment of the roll is checked by two sensors (26,27) and is adjusted by a lateral slider. The programmed width of the new roll is compared with the measured width and the roll position is aligned with the printing requirement. The programmed width values are store as the expected spacing at each side of the roll. The roll is positioned with one edge on a reference mark, or equidistant between the sensors, depending on the print alignment requirements.
