ABSTRACT:
In a printing press, an adjustment system for positioning a rolling element such as a form roller or an impression cylinder relative to a first cylinder having a first diameter and relative to at least a second cylinder adapted to replace the first cylinder and having a second diameter different than the first diameter, the system comprising an actuating member operable to displace the rolling element relative to the first cylinder and having a pivotable fixed first end and a second end mechanically linked to the rolling element, the actuating member providing sufficient displacement to bring the rolling element into contact with the first cylinder such that a predetermined contact pressure therebetween is reached, the actuating member also being operable to bring the rolling element into contact with the second cylinder such that the predetermined contact pressure therebetween is reached. A method for displacing a rolling element is also presented.
