Ferner bezieht sich die Erfindung auf ein Verfahren zum Verstellen von mindestens einem Registerelement in einer Druckmaschine, entsprechend dem Oberbegriff des Anspruchs 8.The invention further relates to a method for adjusting at least one Register element in a printing press, according to the preamble of claim 8.

Vorrichtungen und damit realisierbare Verfahren der hier angesprochenen Art sind bekannt (EP 0 596 337 B1). Dabei dient die Klemmschiene insbesondere einer Bogenoffsetdruckmaschine dazu, eine Druckplatte an einem zugeordneten Plattenzylinder zu befestigen. Aufgrund von sich einstellenden, nicht erwünschten Toleranzen in der Druckmaschine und somit auch am Plattenzylinder ist es notwendig, eine Lageverstellung der Registerelemente (Registerstifte) in Bezug auf eine zu fixierende Druckplattenvorderkante vorzusehen. Es ist aus EP 0 596 337 B1 bekannt, die Registerelemente jeweils relativ zur Klemmschiene mittels eines entsprechend ausgebildeten Befestigungsmechanismus lagezuverstellen. In dieser Weise werden nicht zu vermeidende Ungenauigkeiten beziehungsweise Spiele am Plattenzylinder der Druckmaschine zwischen der Klemmschiene und der zu fixierenden Druckplatte ausgeglichen, so dass eine zu klemmende Druckplatte in präziser und korrekter Weise am Plattenzylinder mittels der mit der Klemmschiene wirkverbundenen Registerelemente befestigt werden kann.Devices and thus realizable methods of the type mentioned here are known (EP 0 596 337 B1). The clamping rail serves in particular a sheetfed offset printing machine to a printing plate on an associated plate cylinder Fasten. Because of tolerances that arise in the Printing machine and thus also on the plate cylinder, it is necessary to adjust the position the register elements (register pins) with respect to a printing plate leading edge to be fixed provided. It is known from EP 0 596 337 B1, the register elements in each case relative to the clamping rail by means of an appropriately designed fastening mechanism lagezuverstellen. In this way, inaccuracies are unavoidable or games on the plate cylinder of the printing machine between the Compensated clamping rail and the pressure plate to be fixed, so that one too clamping plate in a precise and correct manner on the plate cylinder using the the clamping rail can be attached to operatively connected register elements.

Da die Klemmschiene mittels einer verhältnismäßig großen Anzahl an Klemmmitteln (Klemmschrauben) mit dem Plattenzylinder wirkverbunden ist, ist das Lösen dieser Klemmmittel zur anschließenden Lageverstellung der Klemmschiene mit Registerelementen nachteilhafterweise zeitaufwendig und kompliziert.It is also known for the position adjustment of register elements, the whole of Plate cylinder released clamping rail - consisting of an upper clamping rail and one interacting with this lower terminal block - together with the Position register elements. Since the clamping rail is relatively large number of clamping devices (clamping screws) with the plate cylinder is operatively connected, is the loosening of this clamping means for subsequent position adjustment the clamping rail with register elements disadvantageously time consuming and complicated.

Mittels einer während des Verstellvorgangs stets geführten oberen Klemmschiene ist es möglich, unter Einsatz eines geeignet ausgebildeten und mit der oberen Klemmschiene wirkverbundenen Verstellmittels eine schnelle und definierte Verstellung des Registerelements zu erzielen. Dabei ist es nicht notwendig, zur Verstellung des Registerelements die obere Klemmschiene komplett vom Plattenzylinder zu lösen, sondern es besteht aufgrund der vorgesehenen Führung der Klemmschiene auch die Möglichkeit, selbige mittels eines geeigneten Verstellmittels elastisch in eine Verstellrichtung zu verformen beziehungsweise zu verbiegen zur Erzielung einer sich entsprechend einstellenden Positionierung des jeweiligen Registerelements relativ zu der am Plattenzylinder zu befestigenden beziehungsweise zu klemmenden Druckplatte. Nach Einnahme einer gewünschten Betriebsposition der elastisch verformten Klemmschiene beziehungsweise des zugehörigen Registerelements kann die Klemmschiene mittels geeigneter Klemm- oder Spannmittel am Plattenzylinder lagefixiert werden.
