Abstract
A device for mounting, removing and transporting an easily bendable device, such as a printing plate, to and from a plate cylinder includes a printing plate preparation device which supports the plate, and a cross arm with a plate gripper and pressing assembly. A gripper portion of the plate gripper and pressing assembly acts on the plate and is movable toward and away from a suspension strip of a cylinder. The plate gripper and pressing assembly can be moved to a parked position where it is out of the way and is shielded from contaminants.
Claims2
A device for mounting, removing and transporting an easily bendable, curved printing plate having front and rear, dimensionally stable beveled suspension edges which are resistant to being bent open, and whose respective legs form an opening angle (alpha) of less than 90.degree., on and from a cylinder of a rotary printing press, which has at least one suspension strip of a nose-shaped cross section and a closure which engages said rear beveled suspension edge of the printing plate and which has pivotable resilient clamping flaps comprising:
- a gripper and pressing device for a printing plate which is to be removed or mounted, said gripper and pressing device being disposed positionable in and movable to a parked position close to the cylinder;
- and
- linear drives for moving said gripper and pressing device to said parked position and wherein said linear drives include threaded spindles, said parked position being located in an extension of said linear drives in a production direction past a disengagement position determined by the intersection of a perpendicular line drawn from an axis of rotation of the cylinder with said threaded spindles of said linear drives.
