Description

Lagereinstellvorrichtung für die Druckformen von Flach-, Hoch- oder Tiefdruckmaschinen. Bei den üblichen Druckmaschinen sind diejenigen Teile, die für den Druck, bzw. als Widerdruck, in Betracht kommen, in der Regel wohl einstellbar, aber festgelagert. Diese feste Lagerung bedingt eine genaue Zurichtung der Druckformen, weil sonst der Druck unklar oder unscharf wird und gestattet auch keine rasche Regelung während des Arbeitsganges.Bearing adjustment device for the printing forms of flat, portrait or Gravure printing machines. In the case of conventional printing machines, those parts that are for the print, or as reverse print, come into consideration, usually adjustable, but fixed. This fixed storage requires a precise set-up of the printing forms, because otherwise the print becomes unclear or fuzzy and does not allow rapid regulation during the process.

Gegenstand vorliegender Erfindung ist eine hydraulisch oder pneumatisch nachgiebige und einstellbare Lagerung der zur Aufnahme der Druckformen bestimmten Tische, Walzen @u. dgl. In derselben Weise kann auch der Gegendruckzylinder o. dgl. abgestützt werden. Diese Anordnung hat den Vorteil, daß die Zurichtung der Druckform wesentlich erleichtert wird, der Druck während des Arbeitsganges leicht geregelt werden kann und die Formenträger usw. leicht nachgeben können, wenn sich Unterschiede in der Papierstärke, in den Mitläufern usw. finden. Dies hat weiter zur Folge, daß bei verschiedener Spannung der Papierbahn ein Reißen derselben vermieden wird, weil die Zugbeanspruchung im Papier infolge des annähernd gleichbleibenden Druckes an den schwächer beanspruchten Stellen ausgeglichen wird. Außerdem hat man es im Tiefdruckverfahren leicht in der Hand, je nach Art der Tiefdruckplatten mithöherem oder schwächerem Druck zu arbeiten.The present invention is hydraulic or pneumatic flexible and adjustable storage of the intended for receiving the printing formes Tables, rollers @u. Like. In the same way, the impression cylinder o. be supported. This arrangement has the advantage that the preparation of the printing form is made much easier, the pressure is easily regulated during the operation and the mold carriers, etc. can easily give way if there are differences in the paper thickness, in the followers, etc. This also has the consequence that at different tension of the paper web tearing of the same is avoided because the tensile stress in the paper due to the almost constant pressure the less stressed areas are compensated. You also have it in the gravure printing process light in the hand, depending on the type of gravure printing plate with a higher or weaker one Pressure to work.

Die Anordnung wird so getroffen, daß von einem Druckakkumulator aus auf jedes Lager stets mit Hilfe einer gemeinsamen Druckleitung der gleiche Druck eingestellt wird. Man kann natürlich auch so verfahren, daß man auf einzelne Lagerstellen, wenn erforderlich, einen höheren Druck setzen kann.The arrangement is made so that from a pressure accumulator always the same pressure on each bearing with the help of a common pressure line is set. Of course, you can also proceed in such a way that you go to individual storage locations, if necessary, can put a higher pressure.
