Abstract

The screen (5) has a coating of photographic material (6) at least at predetermined intervals. The frame has two lengthwise profiled members (1,2) of spring material and which are joined by two rigid profiled transverse ones (3,4). External force bends the lengthwise members into at leat a part-cylindrical shape, while they spring back into the flat position when this is released. The spring members can be of arched and particularly flat U-section, and they can be of spring sheet-metal. The transverse members can have a quick-acting locking device holding the screen in the form of a screen-printing cylinder.

Description

Die vorliegende Erfindung betrifft eine Siebdruckschablone mit einem Siebdruckschablonenträger in Form eines rechteckigen flachen Gebildes mit einer zumindest in vorbestimmten Abschnitten aus einer Photoschicht bestehenden Beschichtung.The present invention relates to a screen printing stencil with a screen printing stencil carrier in the form of a rectangular flat structure with a at least in predetermined sections from a photo layer existing coating.

Bei der Herstellung von grossformatigen Rotationssiebdruckzylindern stehen heute grundsätzlich zwei Systeme zur Verfügung, nämlich:

  • a) Endlos Zylinder, bei denen die Grundstruktur, d.h. der eigentliche Schablonenträger, als Zylinder hergestellt wird. Die Weiterverarbeitung zu einer druckfähigen Schablone erfolgt am Zylinder selbst. Der Arbeitsablauf ist relativ aufwendig, und die dazu erforderlichen Einrichtungen sind den jeweiligen Zylinderdurchmessern und Zylinderlängen anzupassen. Mit diesen Zylindern ist es möglich, sog. "endlose" Drucke herzustellen.
  • b) Endliche Zylinder, deren Grundstruktur, d.h. der eigentliche Schablonenträger, als flaches Material im Band- oder Bogenformat hergestellt wird. Hier erfolgt die Weiterverarbeitung im flachen Zustand. Als letzter Arbeitsschritt vor dem Druckprozess erfolgt hier die Bildung eines Druckzylinders, was relativ aufwendige und sorgfältige Montageschritte bedingt. Die Verarbeitungseinrichtungen sind praktisch formatunabhängig, da Zylinderdurchmesser und -länge nur einen beschränkten Einfluss haben.
    • There are basically two systems available today for the production of large-format rotary screen printing cylinders, namely:
  • a) Endless cylinders in which the basic structure, ie the actual template carrier, is produced as a cylinder. The further processing into a printable stencil takes place on the cylinder itself. The workflow is relatively complex, and the facilities required for this are to be adapted to the respective cylinder diameters and cylinder lengths. With these cylinders it is possible to produce so-called "endless" prints.
  • b) Finite cylinders, the basic structure, ie the actual template carrier, is produced as a flat material in the form of a ribbon or sheet. Further processing takes place here in a flat state. The last step before the printing process is the formation of a printing cylinder, which requires relatively complex and careful assembly steps. The processing equipment is practically independent of the format, since cylinder diameter and length have only a limited influence.

    • Bei diesen Zylindern ist durch die Zylindernaht immer ein Unterbruch vorhanden. Sie ermöglichen jedoch das kostengünstige Drucken mit Zylindersegmenten, da lediglich im Druckabschnitt eine relativ teure Schablone notwendig ist (der restliche Zylindermantel kann z.B. durch eine kostengünstige Folie gebildet sein).With these cylinders there is always a through the cylinder seam There is an interruption. However, they make it inexpensive Printing with cylinder segments, since only in the printing section a relatively expensive template is necessary (the rest Cylinder jacket can e.g. formed by an inexpensive film be).

    Die heutigen Schablonen dieser Art werden praktisch ausschliesslich als sog. Einwegschablonen eingesetzt, mit Drucklängen bis ca. 650 mm und Druckbreiten bis ca. 400 mm.Today's stencils of this kind are practically exclusive used as so-called disposable stencils, with print lengths up to approx. 650 mm and print widths up to approx. 400 mm.

    Die praktischen Erfahrungen mit herkömmlichen Schablonen haben gezeigt, dass ein Handling von grösseren Formaten kaum möglich ist. Eine Zylinderbildung im Druckwerk selbst und eine Wiederverwendung der Schablone sind praktisch unmöglich.Have practical experience with conventional stencils shown that handling larger formats is hardly possible is. Cylinder formation in the printing unit itself and reuse the template are practically impossible.

    Eine Siebdruckschablone der vorstehend beschriebenen Art ist in der DE-A-2 324 330 offenbart.A screen printing stencil of the type described above is in the DE-A-2 324 330.

    Aufgabe der vorliegenden Erfindung ist die Schaffung von Siebdruckschablonen, welche sich auch für die Bildung von Siebdruckzylindern mit grossen Drucklängen (über 1000 mm) und Druckbreiten (über 700 mm) eignen. Die eigentliche Schablonenherstellung soll dabei im flachen Zustand erfolgen und die Wiederverwendbarkeit des Schablonenträgers gewährleistet sein. Die Bildung zum Druckzylinder im Druckwerk selbst und die Rückführung in den flachen Zustand soll ohne grossen Aufwand möglich sein.The object of the present invention is to create screen printing stencils, which are also suitable for the formation of Screen printing cylinders with large printing lengths (over 1000 mm) and Print widths (over 700 mm) are suitable. The actual template production should be done in a flat state and the Reusability of the template carrier can be guaranteed. The formation of the printing cylinder in the printing unit itself and the Returning to the flat state should be easy to be possible.

    Diese Aufgabe wird bei einen Siebdruckschablone der eingangs definierten Art erfindungsgemäss dadurch gelöst, dass der Schablonenträger unter Bildung einer Siebdruckplatte an einem Hilfsrahmen, bestehend aus zwei Längsprofilen und zwei die beiden Längsprofile miteinander verbindenden steifen Querprofilen, angebracht ist, wobei die Längsprofile aus federndem Material bestehen und im Querschnitt so ausgebildet sind, dass sie sich durch äussere Kraftanwendung aus der flachen Form federelastisch verbiegen lassen, um die die Siebdruckschablone bildende Siebdruckplatte mindestens zu einem Teilzylinder zu formen, sich bei Wegnahme der äusseren Kräfte jedoch selbsttätig wieder in ihre flache Ausgangsform zurückbilden.This task is the beginning of a screen printing stencil defined type according to the invention solved in that the Stencil holder forming a screen printing plate on one Subframe consisting of two longitudinal profiles and two die rigid longitudinal profiles connecting the two longitudinal profiles, is attached, the longitudinal profiles made of resilient Material exist and are designed in cross section so that they come out of the flat shape by external force Let it bend resiliently around which the screen printing template forming screen printing plate at least to form a partial cylinder, when the external forces, however, automatically return to their flat Reduce the original form.

    Dank dem erfindungsgemäss eingesetzten Hilfsrahmen wird eine knitter- und fehlerfreie Schablonenherstellung auch im Grossformat möglich. Ferner ist eine einfache und faltenfreie Zylinderformung direkt im Druckwerk problemlos gewährleistet und ein mehrmaliger Druckeinsatz der Schablone garantiert.Thanks to the subframe used according to the invention, a Wrinkle-free and error-free stencil production also in large format possible. It is also simple and wrinkle-free Cylinder shaping guaranteed directly in the printing unit and multiple use of the stencil is guaranteed.

    Andererseits kann die flache Siebdruckplatte, gebildet aus dem eigentlichen Schablonenträger und dem damit verbundenen Hilfsrahmen, dank der besonderen Ausgestaltung der Rahmen-Längsprofile problemlos im Druckwerk selbst zu einem Zylinder geformt und auf die Zylindernaben aufgesetzt werden, ohne dass dank des geschlossenen Hilfsrahmens der Schablonenträger beschädigt, zerknlttert oder anderweitig verformt würde.On the other hand, the flat screen printing plate formed from the actual template holder and the associated subframe, thanks to the special design of the longitudinal frame profiles easily formed into a cylinder in the printing unit itself and be placed on the cylinder hubs without using the the closed subframe of the template carrier is damaged, crumpled or otherwise deformed.

    Dies wird dadurch möglich, dass die Biegesteifigkeit der Längsprofile beschränkt ist (ausreichend für eine normale Steifigkeit der flachen Platte, jedoch durch normalen äusseren Kraftaufwand verbiegbar). Die Befestigung des eigentlichen Schablonenträgers auf den Längsprofilen des Rahmens, z.B. durch Aufkleben, sollte möglichst im Bereich der neutralen Biegestelle des Profils erfolgen.This is made possible by the fact that the longitudinal profiles are rigid is limited (sufficient for normal stiffness the flat plate, but by normal external force bendable). The attachment of the actual template carrier on the longitudinal profiles of the frame, e.g. by Glue on, if possible in the area of the neutral bending point of the profile.

    Die Rahmenprofile, insbesondere die Längsprofile, sind üblicherweise durch Metallbänder (federhartes Blech) gebildet und weisen einen besonderen Querschnitt (ähnlich den bombierten Storenlamellen) auf, welcher ausreichende Rahmenstabilität im flachen Zustand gewährleistet, jedoch eine Verbiegung (Zylinderformung) durch leichte äussere Krafteinwirkung ermöglicht (nach Ueberschreiten des jeweiligen "Knickpunktes").The frame profiles, especially the longitudinal profiles, are usually formed by metal strips (spring-hard sheet metal) and have a special cross section (similar to the domed ones Blind slats), which has sufficient frame stability in the ensures flat condition, but a bend (Cylinder formation) due to slight external force enabled (after exceeding the respective "break point").

    Besondere Ausführungsformen des erfindungsgemässen Siebdruckschablonenträgers sind in den abhängigen Ansprüchen definiert.Special embodiments of the screen printing stencil support according to the invention are defined in the dependent claims.

    So bilden z.B. die Querprofile des Rahmens einen Schnellverschlussmechanismus (z.B. Z-Profilierung), welche zusammen mit einer Verschlussleiste die Bildung eines geschlossenen Zylinders erlauben. Diese Querprofile erhalten dank dieser Ausbildung auch eine maximale Biegesteifigkeit bei minimaler Blechdicke.For example, the cross profiles of the frame have a quick release mechanism (e.g. Z-Profiling), which together with a sealing strip the formation of a closed Allow cylinders. These cross sections get thanks to this Training also provides maximum bending stiffness with minimal Sheet thickness.

    Da die Siebdruckschablone ausserhalb des Druckwerkes immer als flache Platte vorliegt, ist eine Bearbeitung vor und nach dem Druckeinsatz mittels der im Flachsiebdruck üblichen Geräte und Vorrichtungen möglich (keine Spezialgeräte erforderlich).Since the screen printing stencil outside the printing unit always as flat plate, processing is before and after Use of printing using the devices and conventional in flat screen printing Devices possible (no special equipment required).

    Die einzelnen Rahmenprofile werden üblicherweise durch Verschweissen miteinander verbunden.The individual frame profiles are usually welded connected with each other.

    Die Verbindung des eigentlichen Schablonenträgers (Kunststoff- oder Metallgewebe oder Lochfolie, mit aufgebrachter Photoschicht) mit dem Hilfsrahmen erfolgt vorzugsweise durch Verkleben oder Verschweissen.The connection of the actual template carrier (plastic or metal mesh or perforated film with an applied photo layer) with the Subframes are preferably made by gluing or welding.

    Dank der erfindungsgemässen Ausbildung den Schablone (Hilfsrahmen) lassen sich grossformatige Siebdruckplatten praktisch aller Abmessungen herstellen und als Siebdruckzylinder im rotativen Siebdruck einsetzen. Dabei können die Abmessungen der Längs- und Querprofile des Hilfsrahmens problemlos den jeweiligen Anforderungen angepasst werden.Thanks to the inventive design, the template (Subframe) can be large-format screen printing plates produce practically all dimensions and as a screen printing cylinder use in rotary screen printing. The Dimensions of the longitudinal and transverse profiles of the subframe can be easily adapted to the respective requirements.

    Die erfindungsgemässe Schablonen, welche sich zur Bildung von Druckzylindern eignet, könnte selbstverständlich auch im flachen Zustand, d.h. als Siebdruckplatte, eingesetzt werden.The stencils according to the invention, which are used for formation of printing cylinders, could of course also in the flat state, i.e. used as a screen printing plate will.

    Der eigentliche Siebdruckschablonenträger in Form eines rechteckigen flachen Gebildes besteht üblicherweise aus einem stabilisierten Gewebe oder einer Folie, vorgelocht z.B. als Galvanoschablone oder nachgelocht, z.B. geätzt oder mit Laser bearbeitet.The actual screen printing stencil carrier in the form of a rectangular flat The structure usually consists of a stabilized fabric or a foil, pre-punched e.g. as galvano stencil or punched, e.g. etched or laser processed.

    Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels noch etwas näher erläutert. Es zeigen:

    The invention is explained in more detail below with reference to an embodiment shown in the drawing. Show it:

    Fig. 1 der Zeichnung zeigt schematisch einen Hilfsrahmen, bestehend aus zwei Längsprofilen 1, 2 und zwei damit verschweissten steifen Querprofilen 3, 4. Dieser Hilfsrahmen ist im flachen Zustand relativ stabil, d.h. er bleibt auch bei Manipulationen in der flachen Plattenform. Wie insbesondere auch Fig. 2 zeigt, ist ein Schablonenträger 5 in Form eines stabilisierten Gewebes, insbesondere eines Metallgewebes oder einer Lochfolie, mit darauf mindestens in Abschnitten aufgebrachter Photoschicht 6, beidseitig auf den Längsprofilen 1, 2 des Hilfsrahmens festgemacht (z.B. aufgeklebt). Das Besondere an der ganzen Konstruktion ist nicht nur der Hilfsrahmen allein, sondern die Ausgestaltung der Längsprofile 1, 2: Diese haben im Querschnitt die Form von bombierten Blechlamelien, welche sich durch äussere Krafteinwirkung verbiegen lassen, so dass aus dem mit Hilfsrahmen versehenen Siebdruckschablonenträger auf einfachste Weise ein Druckzylinder gebildet werden kann.Fig. 1 of the drawing shows schematically an existing subframe from two longitudinal profiles 1, 2 and two welded to it stiff cross sections 3, 4. This subframe is relatively stable when flat, i.e. he stays with Manipulations in the flat plate form. How in particular also shows Fig. 2 is a stencil holder 5 in the form of a stabilized tissue, in particular a metal mesh or a perforated film, with at least in sections on it applied photo layer 6, on both sides on the longitudinal profiles 1, 2 of the subframe attached (e.g. glued on). The Not only is that special about the whole construction Subframe alone, but the design of the longitudinal profiles 1, 2: These have the shape of a convex cross section Sheet laminates, which are caused by external forces let it bend, so that from the provided with subframe Screen printing stencil holder in the simplest way Printing cylinder can be formed.

    Um den Zylindermantel zu schliessen, sind die Querprofile vorzugsweise zur Bildung eines Schnellverschlusses (siehe Fig. 3 und 4) zusammen mit einer Schliessleiste 7 ausgebildet.In order to close the cylinder jacket, the cross profiles are preferred to form a quick release fastener (see Fig. 3 and 4) formed together with a locking bar 7.

    Sobald die äusseren Kräfte nicht mehr auf die gebogene Schablone mit Schablonenträger mit Hilfsrahmen einwirken, bildet sich diese automatisch wieder in die flache Plattenform zurück.As soon as the external forces are no longer on the curved template If the stencil carrier acts with the subframe, this forms automatically returns to the flat plate shape.

    Die Befestigung des Schablonenträgers (Gewebe 5, 6) an den Längsprofilen 1, 2 erfolgt bevorzugt im Bereich der neutralen Zone der letzteren (keine Einwirkung beim Verbiegen). Bei Verwendung eines geeigneten Klebstoffes ist der Befestigungsort jedoch unkritisch.The attachment of the template carrier (fabric 5, 6) to the Longitudinal profiles 1, 2 are preferably carried out in the neutral area Zone of the latter (no influence when bending). Using A suitable adhesive is the place of attachment however not critical.

    Die Verbindungsleiste 7 für die Querprofile 3, 4 kann auch von der Seite her aufgeschoben werden. The connecting bar 7 for the cross sections 3, 4 can also by be pushed on the side.

    Der Siebdruckzylinder kann im Druckwerk selbst montiert werden, dies durch Auflegen der sich biegenden Schablone auf seitliche Tragscheiben (Naben) für den Zylinder.The screen printing cylinder can be installed in the printing unit itself, this by laying on the bending template lateral support discs (hubs) for the cylinder.

    Der grosse Vorteil der erfindungsgemässen Siebdruckschablone liegt darin, dass alle Bearbeitungsschritte (u.a. die Herstellung der eigentlichen Druckvorlage; Bearbeitungen zur Wiederverwendung etc.) im flachen Zustand erfolgen können, und dass die Ausbildung als Zylinder auf einfachste Weise auch im Druckwerk selbst erfolgen kann.The great advantage of the screen printing stencil according to the invention lies in the fact that all processing steps (including the production the actual print template; Processing for reuse etc.) in the flat state can be done and that training as a cylinder on easiest way can also be done in the printing unit itself.
