ABSTRACT:
A method for adjusting contact between two rollers of a printing mechanism of a rotary printing press, which rollers are adjustable with respect to their distance relative to one another. The method includes separating the two rollers, driving a first one of the rollers at a first speed, moving the rollers toward one another on one end until they reach a point where the first roller drives a second roller, and sensing rotation of the second roller and registering value data representing the point where the first roller drives the second roller. Next, the rollers are separated after the value data has been registered. Following this separation the method continues with moving the rollers toward one another on a second end until the first roller drives the second roller, sensing rotation of the second roller and stopping movement of the rollers at the second end when rotation of the second roller is sensed. Finally, the first end is adjusted to the point where the first roller drives the second roller.
