Description

Verfahren und Vorrichtung zum Kühlen rundgegossener Stereotypplatten. Rundgegossene Stereotypplatten, insbesondere solche, die weniger als eine halbkreisförmige Länge besitzen, haben beim Kühlen das Bestreben, sieh zu verziehen, so daß sie auf dem Plattenzylinder der Rotationsdruckmaschine nicht satt aufsitzen. Dies erweist sich besonders bei Illustrationsmaschinen, die für Druck bester Qualität bernutzt werden sollen, als nachteilig.Method and device for cooling round cast stereotype plates. Round cast stereotype panels, especially those that are less than a semicircular one Have length, tend to warp when cooling so that they rise Do not sit tightly against the plate cylinder of the rotary printing press. This proves This is particularly useful for commercial printing presses that are used for top quality printing should be considered disadvantageous.

Gemäß der Erfindung werden die Platten während des Küuhlens zwischen der fertigen Platte entsprechend gestaltete Preßflächen unter Druck gestellt. D4durch wird ein: Verziehen der Platten wirksam verhindert und eine solche Genauigkeit in bezug auf Stärke und Gestalt erzielt, daß die besten Druckergebnisse gewährleistet sind.According to the invention, the plates are between during cooling the finished plate correspondingly designed pressing surfaces put under pressure. D4 by is one: warping of the plates is effectively prevented and such accuracy in in terms of strength and shape achieved that ensures the best printing results are.

In den Abb. i und 2 der Zeichnung ist eine Vorrichtung zur Ausführung des Verfahrens beispielsweise schematisch in einer Seitenansicht und im Grundriß veranschaulicht.In Figs. I and 2 of the drawing is a device for execution of the method, for example, schematically in a side view and in plan illustrated.

Die untere Preßfläche a dient zur Aufnahme der zu kühlenden Platte, die mit der Bildseite nach unten hineingelegt wird. Gegen die Rückseite dieser Platte wird ein vollrunder Stempel b mittels der Handschraube c gepreßt. Dieser obere Stempel b wird durch einen- Wassermantel gekühlt. Zur Erhöhung der Kühlwirkung kann auch die untere Preßfläc!he einen Kühlmantel .erhalten.The lower pressing surface a is used to hold the plate to be cooled, which is placed face down. Against the back of this plate a full round punch b is pressed by means of the hand screw c. This upper stamp b is cooled by a water jacket. To increase the cooling effect can also the lower pressing surface will receive a cooling jacket.

Die in dieser Presse unter genügendem Druck gekühlten Platten können sich nicht verziehen und übertreffen im Drucke alle bisher bekannten Stereotypplatten.The plates cooled in this press under sufficient pressure can do not warp and surpass all previously known stereotype plates in print.
