ABSTRACT:
The invention provides a roller assembly including a roller for a damping unit or an inking unit in a rotary printing machine, which is supported relative to rollers via a pressure mechanism with springs, for example, a pressure spring and a leaf spring, so that the weight of the roller is balanced by the leaf spring. In this way, the roller has the same nip widths as the adjacent rollers. In addition, the roller is equipped with a holding mechanism, through which a bedding of the roller that has been set can be clamped, so that the roller has a fixed position during the printing process. The holding mechanism includes, for example, a pneumatic cylinder, a gripping lever or an adjusting screw.
