A plate cylinder of a printing press, with a tensioning channel which extends
in
the axial direction, in which means for fixing the plate ends of at least one printing
plate which can be positioned on the plate cylinder are arranged. The leading plate
end can be fixed by a holding element against a contact surface by means of a tensioning
rail which can be moved in the tensioning channel. After that, and after the plate
cylinder has been rotated, it is then possible to hook the trailing plate end on
the extended tensioning rail. After that, it is possible to draw the tensioning
rail back in again to tension the trailing plate end.
