Description

Die Erfindung betrifft eine Verbesserung an Druckpressen mit pneumatischen Anfeuchtungs- und Farbwalzen.The invention relates to an improvement in printing presses with pneumatic moistening and inking rollers.

Die bislang "bekannten Walzen dieser Art sind so ausgebildet, daß jede Walze aus einem starren, zylindrischen Kern und ein paar Stirnscheiben besteht, an welchen die üblichen Stoffe zur Aufnahme und Übertragung der Farbe oder Feuchtigkeit so befestigt sind, to daß sie eine zylindrische Mantelfläche bilden und zwischen sich und dem Walzenkern einen Spielraum belassen, in dem ein Luftschlauch untergebracht ist, der sich durch ein Ventil an einer der Stirnseitien aufblasen läßt.
Offenbar ist eine derart gebaute Walze sehr elastisch und ermöglicht, den auf die färbende und anzufeuchtende Fläche auszuübenden Druck durch Verstärken oder Verringern des Luftdruckes veränderlich zu machen.
Aber diese Walzen haben den "Nachteil, daß sie unter der Einwirkung der Drücke, denen sie ausgesetzt sind, leicht ihre Gestalt ändern. Hier setzt die Erfindung ein, welche bezweckt, diese Walzen ständig in zylindrischer Form zu halten. Sie besteht darin, daß jede pneumatische Wabe in der Arbeitsstellung entsprechend den Erzeugenden — Mantellängslinien — mit wenigstens drei starren Walzen, die parallel zu ihr sind, in Berührung steht. Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.The previously "known rollers of this type are designed so that each roller consists of a rigid, cylindrical core and a pair of end disks, to which the usual substances for absorbing and transferring the paint or moisture are attached so that they form a cylindrical outer surface and leave a clearance between itself and the roller core, in which an air hose is accommodated, which can be inflated through a valve on one of the end faces.
Apparently, a roller constructed in this way is very elastic and enables the pressure to be exerted on the surface to be colored and moistened to be varied by increasing or decreasing the air pressure.
But these rollers have the "disadvantage that they easily change their shape under the action of the pressures to which they are exposed. This is where the invention comes in, which aims to keep these rollers constantly in a cylindrical shape pneumatic honeycomb in the working position corresponding to the generators - longitudinal lines of the surface - is in contact with at least three rigid rollers which are parallel to it.

Bei dieser Ausführungsform sind die Walzen io« und ίο* sowie die Walzen pneumatische Walzen bekannter Art. Die Walzen ioa und 10* sind Beleuchtungswalzen und berühren als solche einerseits den Zinkzylinder 12 und anderseits die Werkwalze 13.In this embodiment, the rollers io "and ίο * as well as the rollers pneumatic rollers are of known type. The rollers io a and 10 * are lighting rolls and touch than those the one hand, the zinc cylinder and on the other hand, the work roller 13 12.

Zum Vermeiden der Gestaltsänderung des Stoffmantels unter dem Einflüsse des Luftdruckes werden zusätzlich GegendruckwalzenTo avoid the change in shape of the fabric jacket under the influence of air pressure are also counter pressure rollers

14 angeordnet, so daß jede elastische Walze an drei ManteUängslinien geführt ist, um eine zylindrische Form aufrecht zu erhalten.14 arranged so that each elastic roller is guided on three ManteUängslinien to one maintain cylindrical shape.

Die Wasseraufnahmewalze 11 vermag zwischen der festen Werkwalze 13 und der WalzeThe water absorption roller 11 is capable of between the fixed work roller 13 and the roller

15 zu pendeln. In diesem Falle ordnet man daher zwei Gegendruckwalzen i6a und i6* an, um der Walze 11 die zylindrische Form zu bewahren.15 to commute. In this case, therefore, two counter-pressure rollers i6 a and i6 * are arranged in order to keep the roller 11 in its cylindrical shape.
