Bei einer aus DE 195 16 004 A1 bekannten Druckmaschine dieser Art ist an das Gestell eine Platte angelenkt, die mit Lagern zur Aufnahme der Wellenzapfen der freien Enden der Druck- und Rasterwalzen oder mit Aufnahmen für auf die Wellenzapfen aufgesetzte Lager versehen sind Die Platte ist zwischen einer abgeklappten Stellung, in der die fliegend gelagerten Walzen frei zugänglich sind, und einer eingeschwenkten Stellung verschwenkbar, in der die Wellenzapfen der freien Enden der Walzen an der Platte gelagert sind. Bei der bekannten Druckmaschine sind an der schwenkbaren Platte zusätzliche Lager vorgesehen, die die freien Enden der fliegend gelagerten Walzen abfangen und dadurch unerwünschte Schwingungen der freien Enden der fliegend gelagerten Walzen und Durchbiegungen verhindern, die die Druckqualität beeinträchtigen können. Die Platte mit den Lagern läßt sich verhältnismäßig schnell und einfach entfernen, so daß die fliegend gelagerten Walzen von außen zugänglich sind und sich auch die Druckzylinderhülsen einfach und schnell austauschen lassen. Bei den Druckzylindern mit den austauschbare Klischees tragenden Druckhülsen kann es sich um übliche Klischeezylinder und Format- oder Formzylinder handeln.In a printing machine of this type known from DE 195 16 004 A1, the Frame hinged to a plate with bearings for receiving the shaft journals free ends of the printing and anilox rollers or with receptacles for on the shaft journal attached bearings are provided The plate is between a folded Position in which the overhung rollers are freely accessible and a swiveled in Pivotal position in which the shaft journal of the free ends of the Rollers are stored on the plate. In the known printing press are on the pivoting plate additional bearings are provided, which the free ends of the flying intercept stored rollers and thereby undesirable vibrations of the prevent free ends of the overhung rollers and deflections that may affect print quality. The plate with the bearings can be proportionate remove quickly and easily so that the overhung rollers are accessible from the outside and the printing cylinder sleeves are easy and can be replaced quickly. In the case of the printing cylinders with the interchangeable clichés carrying printing sleeves can be conventional plate cylinders and format or form cylinders.

Bei der bekannten Druckmaschine bereitet das Aufsetzen der Abfanglager oder das Anbringen der Halterungen an die bereits auf den Wellenzapfen der Druck- und Rasterwalzen befindlichen Lager gewisse Schwierigkeiten, weil sich die Lager oder Halterungen auf der Innenseite einer türartig verschwenkbaren Platte befinden, so daß einmal die Platte selbst in ihre Verschlußstellung gebracht werden muß und gleichzeitig oder anschließend die Halterungen bzw. Lager in ihre Stellungen gebracht, justiert und verriegelt werden müssen, was jedoch von außen nicht beobachtet werden kann.In the known printing press, the setting up of the interception bearing or the Attach the brackets to those already on the shaft journals of the printing and anilox rollers located camp certain difficulties because the camp or Brackets are located on the inside of a door-like pivotable plate, so that once the plate itself must be brought into its closed position and brought the brackets or bearings into their positions simultaneously or subsequently, must be adjusted and locked, but this is not observed from the outside can be.
