Abstract:
1. A method for setting a contact pressure exerted by a first roller on at least a second roller and third roller in a printing press including: supporting said first roller in a first roller holder; supporting said first roller holder in a frame holder; providing at least two actuators between said roller holder and said frame holder; operating each said actuator for exerting a force directed radially onto said roller holder; forming a resultant force as a vector sum of all forces acting after setting said contact pressure exerted by said first roller against said second and third roller; actuating ones of said actuators having radial forces counteracting said resultant force; setting a value of said radial force of said operated actuators so that their vector sum corresponds to said resultant force; providing a control signal for said at least two actuators; and defining an opening angle between said radially directed force exerted by said at least two actuators and said resultant force as at least 15°.
