Description

Die Erfindung betrifft einen Bogenführungszylinder mit Aufzug in einer Verarbeitungsmaschine nach dem Oberbegriff des unabhängigen Patentanspruchs 1. Als Verarbeitungsmaschinen eignen sich insbesondere Rotationsdruckmaschinen (einschließlich Lackiermaschinen), speziell Offsetdruckmaschinen und/oder Lackierwerke mit mindestens zwei Druck-/Lackwerken für die Verarbeitung von Bedruckstoffen.The invention relates to a sheet guiding cylinder with elevator in a processing machine according to the preamble of independent claim 1. Particularly suitable as processing machines rotary printing machines (including painting), especially offset printing and / or coating with at least two printing / coating units for the processing of substrates.

Bogenführungszylinder mit Aufzug sind in Verarbeitungsmaschinen wie Rotationsdruckmaschinen, insbesondere bei Schöndruck bzw. Schön- und Widerdruckmaschinen, im Einsatz. Derartige Rotationsdruckmaschinen weisen Wendeeinrichtungen nach dem Prinzip der Eintrommelwendung (beispielsweise aus DD 54703 A bekannt) oder der Drei-Trommelwendung (beispielsweise aus DE 11 07 246 A bekannt) auf. Alternativ kann die Rotationsdruckmaschine mit abwechselnd die beiden Seiten des Bogenmaterials bedruckenden Druckwerken ausgebildet sein. Eine derartige Bogendruckmaschine ist beispielsweise aus DE 32 03 879 A1 bekannt.Sheet guiding cylinder with elevator are in processing machines such as rotary printing machines, especially in Perfecting and perfecting machines, in use. Such rotary printing machines have turning devices according to the principle of Eintrommelwendung (for example DD 54703 A known) or the three-drum turn (for example DE 11 07 246 A known). Alternatively, the rotary printing machine may be formed with printing units alternately printing the two sides of the sheet material. Such a sheet-fed printing machine is for example off DE 32 03 879 A1 known.

Im Schön- und Widerdruck wird ein von einem Bogenführungszylinder getragener Bogen auf einer ersten Seite bedruckt und/oder lackiert und danach auf der zweiten Seite bedruckt bzw. lackiert. Dabei kann die frische Farbe bzw. der Lack von der unten liegenden (ersten Seite) des Bogens auf die Mantelfläche des Bogenführungszylinders durch Farb-/Lackrückspaltung ablegen bzw. abschmieren. Um die Mantelfläche nicht zu verschmutzen bzw. das Druck-/Lacksujet auf dem Bogen nicht zu beeinträchtigen wird auf einem Bogenführungszylinder ein Aufzug mit Farbe/Lack abweisender Oberfläche lösbar angeordnet.In perfecting a sheet carried by a sheet guiding cylinder is printed on a first page and / or painted and then printed on the second page or painted. In this case, the fresh paint or the paint from the underlying (first side) of the sheet on the lateral surface of the sheet guiding cylinder by paint / Lackrückspaltung deposit or lubricate. In order not to pollute the lateral surface or not to affect the printing / Lacksujet on the sheet is arranged on a sheet guiding cylinder, a lift with paint / paint repellent surface releasably.

Ein Bogenführungszylinder mit einem Aufzug dieser Art ist aus WO 02/087883 A1 bekannt, der eine spezielle Oberfläche mit einem verbesserten Farbspaltungsverhalten sowie einem verbesserten Verschleißverhalten aufweisen soll. Der Bogenführungszylinder weist einen zylindrischen Grundkörper mit wenigstens einem daran angeordneten Bogenhaltesystem und wenigstens einem in Umfangsrichtung angeordneten Aufzug auf. Der Bogenführungszylinder kann - bezogen auf einen einfachgroßen Formzylinder - als einfachgroßer oder mehrfachgroßer Zylinder ausgebildet sein und dementsprechend in Umfangsrichtung betrachtet einen lösbar angeordneten Aufzug oder mehrere umfangsseitig lösbar angeordnete Aufzüge tragen. Die Aufzüge sind mittels Spannmitteln auf dem Bogenführungszylinder fixiert, wobei die Spannmittel in einem oder mehreren Zylinderkanälen angeordnet sind. Bevorzugt sind in diesen Zylinderkanälen die Bogenhaltesysteme angeordnet.A sheet guiding cylinder with a lift of this kind is made WO 02/087883 A1 known to have a special surface with improved color splitting behavior and improved wear behavior. The sheet guiding cylinder has a cylindrical base body with at least one sheet holding system arranged thereon and at least one elevator arranged in the circumferential direction. The sheet guiding cylinder can - based on a simple-sized forme cylinder - be designed as a single-sized or multi-sized cylinder and accordingly viewed in the circumferential direction wear a detachably arranged elevator or a plurality of circumferentially releasably arranged elevators. The elevators are fixed by means of clamping means on the sheet guiding cylinder, wherein the clamping means are arranged in one or more cylinder channels. The sheet holding systems are preferably arranged in these cylinder channels.

Aus US 6 073 556 A ist eine weiterer Aufzug für einen Bogenführungszylinder bekannt. Der Aufzug umfasst ein flexibles Material und ist locker mittels Spannmitteln fixiert um den Bogenführungszylinder angeordnet.
Die Aufzüge sowie die Spannmittel erstrecken sich - in Zylinderachsrichtung betrachtet - stets über die volle Fläche des Bogenführungszylinders.Out US 6 073 556 A Another elevator for a sheet guiding cylinder is known. The elevator comprises a flexible material and is loosely fixed by clamping means around the sheet guiding cylinder.
The elevators and the clamping means always extend over the full area of the sheet guiding cylinder, viewed in the cylinder axis direction.

Aus DE 11 00 651 A1 ist eine Übergabetrommel mit Bogenhaltesystem für eine Rotationsdruckmaschine bekannt, die zum Verhindern des Abschmierens von aufliegenden Bogen mit Streifen bzw. Bändern ausgestattet ist. In einer speziellen Ausstattung weist die Übergabetrommel auf der Mantelfläche eine Anzahl von in axialer Richtung in Abständen angeordneter Drahtspiralen auf, die in achsparallelen Führungsschienen auf der Trommel verschiebbar sind.Out DE 11 00 651 A1 For example, a transfer drum with sheet holding system for a rotary printing press is known, which is equipped to prevent the smearing of overlying sheets with strips. In a special equipment, the transfer drum on the lateral surface on a number of spaced in the axial direction at intervals wire spirals, which are displaceable in axially parallel guide rails on the drum.

DE 10 2004 043 839 A1 offenbart ein Verfahren zum Betreiben einer Druckmaschine mit einer Bogenwendeeinrichtung und dieser vor- und nachgeordneten Druckzylindern. Mindestens einer der der Bogenwendeeinrichtung nachgeordneten Druckzylinder weist eine Manteloberfläche mit Farbe abweisenden Eigenschaften auf.
Ist die Farbe abweisende Manteloberfläche derart abgenutzt, dass die die Farbe abweisenden Eigenschaften einen vorgebbaren Schwellwert unterschreiten, so wird auf dieser Manteloberfläche eine Folie angeordnet. Die Folie weist wiederum eine Oberfläche mit Farbe abweisenden Eigenschaften auf und ist von der Manteloberfläche des Druckzylinders wiederentfernbar. Dabei soll statt der bekannten Spannmittel ein Haftvermittler zum Fixieren der Folie auf der inzwischen abgenutzten Manteloberfläche eingesetzt werden. Bevorzugt wird die Folie unter Zwischenfügen des Haftvermittlers auf den Druckzylinder aufgebracht. Mögliche Kleberückstände auf der Oberfläche sollen durch Aufschmelzen zum Befestigen einer neuer Folie wieder verwendbar sein. DE 10 2004 043 839 A1 discloses a method of operating a printing press with a sheet turning device and these upstream and downstream printing cylinders. At least one of the bow turning device downstream Printing cylinder has a mantle surface with color-repellent properties.
If the color-repellent mantle surface is worn in such a way that the color-repellent properties fall below a predefinable threshold value, then a film is arranged on this mantle surface. The film in turn has a surface with color-repellent properties and is removable from the mantle surface of the printing cylinder. In this case, instead of the known clamping means, a bonding agent for fixing the film to be used on the now worn jacket surface. Preferably, the film is applied to the printing cylinder with the interposition of the adhesion promoter. Possible adhesive residues on the surface should be reusable by melting to secure a new film.

Aufgabe der Erfindung ist es, einen Bogenführungszylinder der eingangs genannten Art zu schaffen, der für die abschmierfreie Förderung von Bogenmaterial, insbesondere mit großen Formatbreiten, ausgelegt ist.The object of the invention is to provide a sheet guiding cylinder of the type mentioned, which is designed for the smear-free promotion of sheet material, especially with large format widths.

Gelöst wird die Aufgabe durch die Ausbildungsmerkmale von Patentanspruch 1. Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.The problem is solved by the training features of claim 1. Further developments will become apparent from the dependent claims.

Ein erster Vorteil der Erfindung ist darin begründet, dass durch die Ausbildung wenigstens eines Bogenführungszylinders mit einem nachstehend beschriebenen Aufzug die Handhabbarkeit des Aufzuges bei der Montage bzw. Demontage auf dem Bogenführungszylinder verbessert wird. Der Aufzug ist dabei biegbar ausgebildet und ist haftfest und lösbar an dem Bogenführungszylinder angeordnet. Vorzugsweise weist der Aufzug eine Farbe und/oder Lack abweisende Oberfläche auf. Bevorzugt kann der Aufzug ein Trägermaterial aufweisen, welches aus einem relativ leichten, metallischen Material oder einem Kunststoffmaterial gebildet ist und mit der Unterseite der Mantelfläche des Bogenführungszylinders zugeordnet ist. Auf der Oberseite des Trägermaterials kann haftfest eine Beschichtung mit einem unregelmäßigen Oberflächenprofil aus wenigstens einem Metall, Mischungen bzw. Legierungen davon angeordnet sein. Auf der Oberseite dieser Beschichtung kann eine Farbe und/oder Lack abweisende Versiegelungsschicht aus der Gruppe der Polyorganosiloxane oder der Gruppe der Acrylate oder der Gruppe der Fluorpolymere angeordnet sein.A first advantage of the invention is that the design of at least one sheet guiding cylinder with an elevator described below improves the handling of the elevator during assembly or disassembly on the sheet guiding cylinder. The elevator is designed bendable and is adherent and releasably arranged on the sheet guiding cylinder. Preferably, the elevator has a paint and / or varnish-repellent surface. Preferably, the elevator may comprise a carrier material, which is formed from a relatively light, metallic material or a plastic material and is associated with the underside of the lateral surface of the sheet guiding cylinder. On the upper side of the carrier material, a coating having an irregular surface profile of at least one metal, mixtures or alloys thereof may be adhesively bonded. On top of this coating may be a color and / or paint repellent sealing layer from the group the polyorganosiloxanes or the group of acrylates or the group of fluoropolymers.

Ein zweiter Vorteil besteht darin, dass der Bogenführungszylinder bezogen auf einen einfachgroßen Platten-/Formzylinder einfachgroß (eintourig) oder mehrfachgroß, insbesondere doppeltgroß (1/2-tourig) bzw. (1/3-tourig) etc. ausgebildet sein kann, einschließlich deren Kombinationen innerhalb der Verarbeitungsmaschine. Ebenso können die Bogenführungszylinder zumindest eine Mantelfläche aufweisen, welche - bezogen auf einen theoretischen Zylinderdurchmesser - als Vollzylinder ausgebildet ist oder vorzugsweise bei mehrfachgroßer Ausbildung innerhalb des theoretischen Zylinderdurchmessers angeordnete Mantelflächen umfasst.
Auf jeder der Mantelflächen eines Bogenführungszylinders ist ein bereits beschriebener Aufzug lösbar haftfest angeordnet.A second advantage is that the sheet guiding cylinder can be formed in one-sized (one-turn) or multiple-size, especially double-sized ( 1 / 2- speed) or ( 1 / 3- speed), etc., in terms of a single-size plate / plate cylinder, including the same Combinations within the processing machine. Likewise, the sheet guiding cylinders may have at least one lateral surface which, based on a theoretical cylinder diameter, is designed as a solid cylinder or preferably comprises lateral surfaces arranged within the theoretical cylinder diameter in the case of multiple-sized formation.
On each of the lateral surfaces of a sheet guiding cylinder, an already described elevator is releasably adherent.

Als dritter Vorteil kann aufgeführt werden, dass zumindest ein derartiger Bogenführungszylinder keine Farbe abweisende Oberfläche der Mantelfläche bzw. Mantelflächen aufweisen muss, auf die erst nach deren Abnutzung ein Aufzug aufgeklebt wird. Der oder die Aufzüge sind in vorteilhafter Weise bereits vor Druckbeginn auf wenigstens einem Bogenführungszylinder haftfest angeordnet. Dabei ist eine Farbe abweisende, sich abnutzende Oberfläche auf wenigstens einem Bogenführungszylinder nicht erforderlich und somit ist ein derartiger Bogenführungszylinder kostengünstiger herstellbar. Die haftfeste Anordnung jedes Aufzugs ist dabei stets vom Bogenführungszylinder wieder lösbar. Damit kann bei Bedarf jeweils ein abgenutzter Aufzug vom Bogenführungszylinder bzw. dessen Mantelfläche(n) entfernt werden und zumindest ein neuer Aufzug am Bogenführungszylinder lösbar haftfest angeordnet werden.As a third advantage can be listed that at least one such sheet guiding cylinder does not have to have a color-repellent surface of the lateral surface or lateral surfaces, to which a lift is glued only after their wear. The elevator (s) are advantageously adhered to at least one sheet guiding cylinder even before the start of printing. In this case, a color-repellent, wearing surface on at least one sheet guiding cylinder is not required and thus such a sheet guiding cylinder is less expensive to produce. The adherent arrangement of each elevator is always detachable from the sheet guiding cylinder. Thus, if required, a worn elevator can be removed from the sheet guiding cylinder or its lateral surface (s) and at least one new elevator can be releasably adhered to the sheet guiding cylinder.

Ein vierter Vorteil ergibt sich daraus, dass wenigstens ein Bogenführungszylinder über die Formatbreite mehrere lösbar haftfest angeordnete Teilaufzügen aufweisen kann. Durch die haftfeste Anordnung der Teilaufzüge auf zumindest einer Mantelfläche des Bogenführungszylinders wird deren Planlage auf dem Bogenführungszylinder verbessert und ein möglicher Verzug spürbar vermieden. In bevorzugter Ausbildung kann jeder einzelne Teilaufzug auf dem Bogenführungszylinder einzeln justiert und haftfest lösbar angeordnet werden.A fourth advantage results from the fact that at least one sheet guiding cylinder can have a plurality of detachably adhering partial lifts over the width of the format. Due to the adherent arrangement of the partial lifts on at least one lateral surface of the sheet guiding cylinder whose flatness is improved on the sheet guiding cylinder and a possible delay noticeably avoided. In a preferred embodiment, each individual sub-elevator on the sheet guiding cylinder individually adjusted and adherently releasably arranged.

Als fünfter Vorteil ist zu nennen, dass der eine Aufzug oder die den Aufzug bildenden Teilaufzüge nicht auf Farbe und/oder Lack abweisende Aufzüge (mit oder ohne Beschichtung) beschränkt sind. Vielmehr können derartige Aufzüge bzw. Teilaufzüge auch als einfache metallische Aufzüge ausgebildet sein. Beispielsweise kann ein Bogenführungszylinder Teilaufzüge aus Stahlblechen oder Chromplatten oder Aluminiummaterial tragen. Diese Ausführungen eignen sich bevorzugt für Bogenführungszylinder mit Aufzügen/Teilaufzügen, denen zumindest eine Trenneinrichtung( einschließlich Perforiereinrichtung), beispielsweise eine Längsschneideinrichtung, zugeordnet ist. Alternativ sind einfache metallische Aufzüge auf einem Bogenführungszylinder angeordnet, welcher mit einer benachbarten Kalander -, Nut -, Präge -, Rillen -, Ritz - oder Stanzeinrichtung, alternativ einem Druck-/Lackwerk, zusammenwirkt.The fifth advantage is that the elevators or the elevators forming the elevator are not limited to paint and / or paint-repelling elevators (with or without coating). Rather, such elevators or partial lifts can also be designed as simple metallic lifts. For example, a sheet guiding cylinder can carry partial lifts made of steel sheets or chrome plates or aluminum material. These embodiments are preferably suitable for sheet guiding cylinders with elevators / part elevators, which at least one separating device (including perforating), for example, a longitudinal cutting device, is assigned. Alternatively, simple metallic elevators are arranged on a sheet guiding cylinder, which cooperates with an adjacent calender, groove, embossing, grooving, scoring or punching device, alternatively a printing / coating unit.

Im vorliegenden Beispiel sind die als Druck-/Transferzylinder ausgebildeten Bogenführungszylinder 1, 2 - bezogen auf einen einfachgroßen Platten-/Formzylinder 4 - doppeltgroß ausgebildet und weisen in an sich bekannter Weise bevorzugt umfangsseitig zwei diametral angeordnete Zylinderkanäle für die Aufnahme von Bogenhaltesystemen und somit zwei Mantelflächen I, II als Tragflächen für das Bogenmaterial auf. Zwischen beiden Bogenführungszylindern 1 der Druckwerke A, B ist beispielhaft eine Bogenwendeeinrichtung 5, 6, 7 angeordnet. Die gezeigte Bogenwendeeinrichtung 5 bis 7 ist als Drei-Trommel (Zylinder)-Wendung nach dem Prinzip der Hinterkantenwendung ausgebildet. Dabei ist in Förderrichtung 8 des Bogenmaterials ein erster Transferzylinder 5 (Bogenführungszylinder) angeordnet, welcher baugleich zu einem Bogenführungszylinder 2 sein kann. Dem ersten Transferzylinder 5 folgt ein Speicherzylinder 6 (Bogenführungszylinder) und diesem folgt ein das Bogenmaterial im Schöndruck oder im Schön- und Widerdruck führender Wendezylinder 7. Analog zu den bereits beschriebenen Bogenführungszylindern 1, 2 sind die Bogenführungszylinder 5, 6, 7 der Bogenwendeeinrichtung beispielsweise doppeltgroß ausgebildet.
Alternativ kann die als Drei-Trommel (Zylinder)-Wendung gezeigte Bogenwendeeinrichtung auch als an sich bekannte Eintrommelwendung ausgebildet sein.In the present example, the trained as a pressure / transfer cylinder sheet guiding cylinders 1, 2 - based on a single-sized plate / forme cylinder 4 - double-sized and have in a conventional manner preferably circumferentially two diametrically arranged cylinder channels for receiving sheet holding systems and thus two lateral surfaces I, II as wings for the sheet material. Between both sheet guiding cylinders 1 of the printing units A, B, a sheet turning device 5, 6, 7 is arranged by way of example. The illustrated sheet turning device 5 to 7 is formed as a three-drum (cylinder) turn on the principle of trailing edge use. In this case, in the conveying direction 8 of the sheet material, a first transfer cylinder 5 (sheet guiding cylinder) is arranged, which may be identical to a sheet guiding cylinder 2. The first transfer cylinder 5 is followed by a storage cylinder 6 (sheet guiding cylinder) and this follows the sheet material in Perfecting or perfecting leading turning cylinder 7. Analogous to the already described sheet guiding cylinders 1, 2, the sheet guiding cylinders 5, 6, 7 of the sheet turning device are, for example, double-sized.
Alternatively, the sheet turning device shown as a three-drum (cylinder) turn may also be formed as a percussion application known per se.

Im vorliegenden Beispiel tragen die Bogenführungszylinder/Druckzylinder 1 des zweiten Druckwerkes B sowie des dritten Druckwerkes C jeweils auf der Mantelfläche I, II angeordnete biegbare Aufzüge 9, welche in Umfangsrichtung angeordnet sind. Alternativ kann ein Bogenführungszylinder/Druckzylinder 1 eines Lackwerks derartige Aufzüge 9 tragen.In the present example, the sheet guiding cylinder / impression cylinder 1 of the second printing unit B and the third printing unit C each carry on the lateral surface I, II arranged flexible elevators 9, which are arranged in the circumferential direction. Alternatively, a sheet guiding cylinder / impression cylinder 1 of a coating unit can carry such elevators 9.

Ein jeder der Aufzüge 9 kann aus einem einteiligen Stück oder aus mehreren über die Formatbreite angeordneten, zusammengesetzten Teilaufzügen bestehen, die die jeweilige Mantelfläche I, II bedecken. Ein derartiger Aufzug 9 (einteilig oder mehrteilig) weist an der Unterseite einen daran fixierten Haftvermittler 10 (Klebstoff) auf. Der Haftvermittler 10 kann beispielsweise aus der Gruppe der Schmelzklebstoffe (hot melts) sein. Mittels des Haftvermittlers 10 ist der Aufzug 9 an einer Mantelfläche I, II des Bogenführungszylinders 1 lösbar haftfest angeordnet. Der eingesetzte Haftvermittler 10 kann vollflächig oder zonal oder punktuell auf der Unterseite des Aufzugs 9 fixiert sein. Bevorzugt erfolgt der Auftrag des Haftvermittlers 10 bereits im Zusammenhang mit dem oder im Anschluss an den Herstellungsprozess des Aufzuges 9.Each of the elevators 9 may consist of a one-piece piece or of several arranged over the format width, composite part elevators covering the respective lateral surface I, II. Such an elevator 9 (one-piece or multi-part) has on the underside a bonding agent 10 (adhesive) fixed thereto. The bonding agent 10 may be, for example, from the group of hot melt adhesives (hot melts). By means of the adhesion promoter 10, the elevator 9 is releasably adhered to a lateral surface I, II of the sheet guiding cylinder 1. The adhesion promoter 10 used can be fixed over the entire surface or zonally or selectively on the underside of the elevator 9. The application of the adhesion promoter 10 preferably takes place in connection with or following the production process of the elevator 9.

In einer weiteren Ausbildung kann der Aufzug 9 ein Trägermaterial 11 aufweisen an dessen Unterseite der fixierte Haftvermittler 10 angeordnet ist. Bevorzugt ist das Trägermaterial 10 bzw. der Aufzug 9 aus einem relativ leichten, metallischen Material oder einem Kunststoffmaterial gebildet. Beispielsweise kann das metallische Material ein relativ dünnes rostfreies Edelstahlblech oder ein entsprechendes Aluminiumblech oder ein entsprechendes Kunststoffmaterial sein.In a further embodiment, the elevator 9 may have a carrier material 11 on the underside of which the fixed adhesion promoter 10 is arranged. Preferably, the carrier material 10 or the elevator 9 is formed from a relatively light, metallic material or a plastic material. For example, the metallic material may be a relatively thin stainless steel sheet or a corresponding aluminum sheet or plastic material.

Das Trägermaterial 10 trägt haftfest auf der Oberseite eine Beschichtung 12 mit einem unregelmäßigen Oberflächenprofil aus wenigstens einem Metall, Mischungen bzw. Legierungen davon. Geeignete Materialien für die Beschichtung 12 sind: Chrom, Eisen, Titan, Nickel, Kobalt oder Wolfram, deren Oxide wie Al2O3, TiO2, Cr2O3, SiO2 oder ZrO2, deren Karbide wie WC, Cr3C2 bzw. Silizide dieser Metalle, Mischungen oder Legierungen davon, beispielsweise NiCr. Alternativ ist Molybdän (Mo) einsetzbar.The carrier material 10 adhesively bears on the upper side a coating 12 with an irregular surface profile of at least one metal, mixtures or alloys thereof. Suitable materials for the coating 12 are: chromium, iron, titanium, nickel, cobalt or tungsten, their oxides such as Al 2 O 3 , TiO 2 , Cr 2 O 3 , SiO 2 or ZrO 2 , their carbides such as WC, Cr 3 C 2 or silicides of these metals, mixtures or alloys thereof, for example NiCr. Alternatively, molybdenum (Mo) can be used.

Auf der Oberseite dieser Beschichtung 12 ist haftfest eine Farbe und/oder Lack abweisende Versiegelungsschicht 13 aus der Gruppe der Polyorganosiloxane oder der Gruppe der Acrylate oder der Gruppe der Fluorpolymere angeordnet. Auf dieser Versiegelungsschicht 13 wird das Bogenmaterial geführt.On the upper side of this coating 12, a color and / or lacquer-repellent sealing layer 13 from the group of the polyorganosiloxanes or the group of the acrylates or the group of the fluoropolymers is adhesively bonded. On this sealing layer 13, the sheet material is guided.

In einer Weiterbildung kann der an der Unterseite des Aufzugs 9 oder des Trägermaterials 11 fixiert angeordnete Haftvermittler 10 an der gegenüberliegenden, freien Seite eine abziehbare Schutzfolie 14 tragen.In a further development, the adhesion promoter 10 fixedly arranged on the underside of the elevator 9 or of the carrier material 11 can carry a removable protective film 14 on the opposite, free side.

Alternativ kann der Aufzug 9 aus einer Mehrzahl von Teilaufzügen gebildet sein, wobei die Teilaufzüge über die Formatbreite (in Achsrichtung) des Bogenführungszylinders 1 angeordnet sind. Dabei sind über die Formatbreite betrachtet die Seitenkanten der Teilaufzüge in Stoss-an-Stoss-Montage angeordnet. Die Teilaufzüge weisen wiederum an der Unterseite jeweils einen fixierten Haftvermittler 10 auf und mittels des Haftvermittlers 10 wird der aus einer Mehrzahl von Teilaufzügen gebildete Aufzug 9 lösbar haftfest am Bogenführungszylinder 1 angeordnet.Alternatively, the elevator 9 may be formed from a plurality of sub-elevators, wherein the sub-elevators over the format width (in the axial direction) of the sheet guiding cylinder 1 are arranged. The side edges of the part elevators are arranged in push-to-push installation, viewed over the width of the format. The sub-elevators in turn each have a fixed adhesion promoter 10 on the underside, and by means of the adhesion promoter 10, the elevator 9 formed from a plurality of sub-elevators is detachably adhered to the sheet-guiding cylinder 1.

Der einteilige oder mehrteilige Aufzug 9 weist an der Unterseite einen daran fixierten Haftvermittler 10 zum Fixieren auf der jeweiligen Mantelfläche I, II eines Bogenführungszylinders 1 auf.The one-piece or multi-part elevator 9 has at the bottom thereof a bonding agent 10 fixed thereto for fixing on the respective lateral surface I, II of a sheet guiding cylinder 1.

Die Wirkungsweise ist wie folgt. Bei einem einteiligen oder mehrteiligen Aufzug 9 bzw. einem entsprechenden Trägermaterial 10 mit jeweils an der Unterseite angeordnetem Haftvermittler 10 wird der Haftvermittler 10 mit der entsprechenden Mantelfläche I, II in Kontakt gebracht und eine stoffschlüssige Klebstoffverbindung, d.h. mittels Adhäsionskräften, mit dem Bogenführungszylinder/Druckzylinder 1 erzeugt. Bei der Anordnung von Teilaufzügen werden diese in Stoß-an-Stoß-Montage auf der jeweiligen Mantelfläche I, II haftfest angeordnet.
Hierbei kann je nach Art des Haftvermittlers 10 beispielsweise eine aktivierte thermische Quelle oder Strahlungsquelle die Erzeugung der stoffschlüssigen Klebstoffverbindung unterstützen. Diese Quelle kann die Trocknungs- / Strahlungsquelle 15 sein. Der Haftvermittler 10 ist wie beschrieben bereits vor der Erzeugung der stoffschlüssigen Klebstoffverbindung von Aufzug 9 bzw. Trägermaterial 10 mit der jeweiligen Mantelfläche I, II des Bogenführungszylinders/Druckzylinders 1 an der Unterseite von Aufzug 9 bzw. Trägermaterial 10 fixiert worden. Bevorzugt kann das Fixieren des Haftvermittlers 10 durch Aufspritzen oder Auftragen auf die Unterseite des Aufzuges 9 bzw. des Trägermaterials 10 im Zusammenhang oder im Abschluss des Herstellungsprozesses erfolgen.The mode of action is as follows. In a one-piece or multi-part elevator 9 or a corresponding carrier material 10 with each arranged on the underside adhesive 10 of the bonding agent 10 is brought into contact with the corresponding lateral surface I, II and a cohesive adhesive connection, ie by means of adhesion forces, with the sheet guiding cylinder / impression cylinder. 1 generated. In the arrangement of sub-elevators, these are in shock-to-joint assembly arranged adherently on the respective lateral surface I, II.
Depending on the nature of the adhesion promoter 10, an activated thermal source or radiation source, for example, may assist in the production of the adhesive adhesive connection. This source may be the drying / radiation source 15. As already described, the adhesion promoter 10 has already been fixed to the underside of the elevator 9 or carrier material 10 prior to the production of the adhesive adhesive connection of elevator 9 or carrier material 10 with the respective jacket surface I, II of the sheet guiding cylinder / printing cylinder 1. The fixing of the adhesion promoter 10 may preferably take place by spraying or application to the underside of the elevator 9 or the carrier material 10 in connection or at the end of the production process.

Bevorzugt weist der an der Unterseite fixierte Haftvermittler 10 im Wesentlichen eine gleiche Dicke auf. Auf dem Haftvermittler 10 kann die Schutzfolie 14 angeordnet sein, welche bei Bedarf (vor dem Erzeugen der Klebstoffverbindung) vorzugsweise durch Abziehen vom Haftvermittler 10 entfernbar ist.Preferably, the adhesion promoter 10 fixed on the underside has essentially the same thickness. On the bonding agent 10, the protective film 14 may be arranged, which is preferably removable by peeling off the adhesion promoter 10 if necessary (before the production of the adhesive compound).

Der derart auf einer Mantelfläche I oder II des Bogenführungszylinders / Druckzylinders 1 angeordnete ein- oder mehrteilige Aufzug 9 (einschließlich dessen Trägermaterial 11) kann bei Bedarf beispielsweise durch Abschälen oder mittels thermischer Beeinflussung vom Bogenführungszylinder/Druckzylinder 1 aus der ansonsten haftfesten Klebstoffverbindung wiederum gelöst werden.The thus arranged on a lateral surface I or II of the sheet guiding cylinder / printing cylinder 1 single or multi-part elevator 9 (including the carrier material 11) can be solved if necessary, for example, by peeling or by thermal interference from the sheet guiding cylinder / impression cylinder 1 from the otherwise adhesive adhesive bond again.
