Abstract
A device and method for performing a printing plate change on a plate cylinder of a printing press is disclosed. The device includes a rolling element featuring several rollers for pressing at least one printing plate on the plate cylinder during a printing plate change. A strip bearing several alignment elements extends parallel to the rolling element, where a printing plate can be aligned true-to-register between every two adjacent alignment elements before the printing plate is clamped in a lockup slot of the plate cylinder.
Claims12
A device for performing a printing plate change on a plate cylinder of a printing press, with a rolling element featuring several rollers for pressing a printing plate on the plate cylinder during a printing plate change, wherein a strip bearing several alignment elements extends parallel to the rolling element, wherein a printing plate is alignable true-to-register between every two adjacent alignment elements before the printing plate is clamped in a lockup slot of the plate cylinder.
A device for positioning a printing plate on a plate cylinder of a printing press, comprising:
- a strip including a first alignment element and a second alignment element;
- a first centering pin disposed at a first end of the strip and a second centering pin disposed at a second end of the strip;
- a plurality of rollers disposed within the strip and between the first and second alignment elements;
- and
- a clamping element coupled to the strip and disposed between the first and second alignment elements.
A method for positioning a printing plate on a plate cylinder of a printing press, comprising the steps of:
- positioning a strip on the plate cylinder by inserting a first centering pin disposed at a first end of the strip and a second centering pin disposed at a second end of the strip into a first recess defined by the plate cylinder and a second recess defined by the plate cylinder, respectively;
- and
- positioning the printing plate between a first alignment element and a second alignment element disposed on the strip.
