Abstract
A pressure force exerted by first and second cylinders upon at least a third cylinder in a printing machine is regulated by a pressure regulating device. The device can also be using for moving a first cylinder and at least one second cylinder into and out of contact with a third cylinder. Actuators, which exert a radial force on a cylinder cooperating with the actuators, are provided. An aperture angle between the radial forces exerted by two actuators on the same cylinder is the same in both cylinders. That aperture angle is independent of an aperture angle formed by the pressure force exerted by the first and second cylinders on the third cylinder.
Claims14
A device for setting a contact pressure exerted by a first roller and a second roller on at least a third roller and for engagement and disengagement of said first and second roller with said at least third roller in a printing press comprising:
- at least first and second actuators in each of said first and second rollers;
- means for operating said at least first and second actuators in each of said first and second rollers for each said actuator exerting a radial force directed onto said third roller in operative contact with each said first and second rollers;
- a first opening angle determined by said radial forces directed by said at least first and second actuators in each said first and second roller;
- a vector sum of said radial forces of each said first and second roller, each said vector sum exerting a contact pressure on said third roller;
- roller holders supporting each of said first and second rollers;
- and
- frame holders supporting said roller holders, each said frame holder including a housing, said housing receiving said actuators for said associated roller.
