ABSTRACT:
An arrangement for fastening a flexible printing plate on a form cylinder of a printing press. The form cylinder having at least one axially directed cavity with a first wall that terminates at an acute angle with an outer surface of the cylinder so as to form an edge on which a leading leg of the printing plate is supportable, and a second wall on which a trailing leg of the printing plate is contactable. A spindle is mounted in the cylinder cavity so as to be swivelable about a longitudinal axis. Additionally, a plurality of first and second plate-like springs are distributed along and fastened to the spindle so that the first springs press the leading plate leg against the first wall of the cavity and the second springs press the trailing plate leg against the second wall of the cavity, and so that swiveling of the spindle disengages the springs from the plate legs.
