Aufgrund der heutzutage zur Verfugung siehenden Klebebandbreiten ist es dabei eilordeihch. daß mehreie Klebebänder nebeneinander auf den Druckzv linder geklebt w erdenFlexo printing is a rotary high-pressure process for printing on packaging materials, for example. Forms. Foils or the like, in which printing plates, preferably made of photopolymers or rubber, are glued to the printing cylinders. In order to enable the clichés to be attached easily, it is known to refer to the Apply a double-sided adhesive tape on which the cliché is stuck again. Due to the adhesive tape widths available today, it is extremely easy. that several adhesive tapes are glued side by side on the printing cylinder
Um eine einw andfreie Befestigung des Klischees sicherzustellen, insbesondere dann, wenn \ eιschιedene Klischees auf veischiedenen Druckwaizen aufgebracht werden, um Farbdrucke herstellen zu können, muß darauf geachtet w erden, daß der Druckz\ linder flächig und ohne Überlappung mit dem doppelseitigen Klebeband versehen wird. Dies bereitet jedoch eiheb che Schw ierigkeiten und ist mit einfachen technischen Maßnahmen bisher nicht möglich Nach der DE 39 17 S42 A I ird ein Ring auf einen Zylinder einer Transportvor- πchtung w ie Rollgang mittels eines Doppelklebebands befestigt, dessen Breite des Rings entspricht.In order to ensure that the cliché is fixed without any problems, particularly when clichés are applied to various printing presses in order to be able to produce color prints, care must be taken that the printing cylinder is provided with the double-sided adhesive tape overlap and without overlap. However, this causes considerable difficulties and has so far not been possible with simple technical measures According to DE 39 17 S42 AI, a ring is attached to a cylinder of a transport device such as a roller table by means of double-sided adhesive tape, the width of which corresponds to the ring.
Um Enden von von Spulen abzuwickelnden Bahnen untereinander zu verbinden, sind nach der DE 34 16 356 AI Klebebänder vorgesehen. Die miteinander verbundenen Bahnen werden sowohl zwischen stationären als auch verschwenkbaren Walzen gefuhrt.In order to connect ends of webs to be unwound from coils, adhesive tapes are provided according to DE 34 16 356 AI. The interconnected webs are guided between both stationary and swiveling rollers.
In der alteren, jedoch nicht vorveröffentlichten DE 195 25 403 AI wird ein doppelseitiges Klischeeklebeband für die Druckindustrie beschrieben.In the older, but not pre-published DE 195 25 403 AI, a double-sided cliché tape for the printing industry is described.
Um Druckplatten positionsgenau auf einen Druckzylinder auszurichten, ist nach der EP 0 144 334 B l eine die Druckplatte aufnehmende Hilfsschiene vorgesehen, die auf die Langsachse des linders ausrichtbar istIn order to align printing plates with a precise position on a printing cylinder, an auxiliary rail which accommodates the printing plate is provided according to EP 0 144 334 B1, which is arranged on the longitudinal axis of the can be aligned
Der \ orliegenden Erfindung liegt das Problem zugrunde, eine Vorrichtung der eingangs genannten Art zur Verfugung zu stellen, mit der sichei gestellt ist. daß ein einwandfreies Bekleben des Druckz lmdeis mit einem doppelseitigen Klebeband möglich ist, ohne daß dieses ubei l ppt oder bei nebeneinander anzuordnenden Klebebandern diese zueinander beabstandet sind. Außerdem sollen Luftblasen oder Falten ausgeschlossen sein.The problem underlying the present invention is to provide a device of the type mentioned at the outset with which it is ensured. that a perfect gluing of the Druckz lmdeis with a double-sided adhesive tape is possible without this ubei l ppt or with adhesive tapes to be arranged side by side, these are spaced apart. In addition, air bubbles or wrinkles should be excluded.
Das Problem w ird eifindungsgemaß im w esentlichen dadurch gelost, daß die Vor- πchtung eine Halterung umfaßt, in der achsparallel zu dem Druckzylinder die Rolle des Doppelklebebandes gelagert ist. daß die Halterung ein auf das doppelseitige Klebeband in Richtung des hndeιs einw irkendes Anpresselement aufweist und daß von der Halterung eine Schneide in Richtung mit einem achsparallel verlaufenden Schneid- eiement ausgeht. Dabei ist insbesondere das Anpresselement schwerkraftbedingt oder durch gezielte Krafteinleitung über z B. Zylinder, Gewichte verschiebbar in der Halte- l u g Gelage t und als Rolle ausgebildet. oThe problem is essentially solved in accordance with the invention in that the device comprises a holder in which the roll of the double-sided adhesive tape is mounted parallel to the axis of the printing cylinder. that the bracket on the double-sided tape in the direction of hndeιs acting contact pressure element and that from the holder a cutting edge in the direction with an axially parallel cutting element. In this case, the contact pressure element is, in particular, caused by gravity or by means of targeted force introduction, for example by means of cylinders, weights, which can be displaced in the retainer structure and is designed as a roller. O
Durch die erfindungsgemaße Lehre ist sichergestellt, daß mehrere doppelseitige Klebe- bandrollen Stoß an Stoß auf einer gemeinsamen Welle angeordnet werden, wobei beim Abziehen des doppelseitigen Klebebandes von jeder Rolle sichergestellt ist, daß diese im Randbereich Stoß an Stoß auf dem Druckzylinder aufgebracht werden, ohne daß sich eine Lücke ausbildet oder eine Überlappung erfolgt; denn dadurch, daß die doppelseitigen Klebebandrollen auf einer achsparallel zur Längsachse, also Welle des Druckzylinders verlaufenden Welle anordbar sind, ist eine fluchtende Ausrichtung möglich. Femer ist sichergestellt, daß das doppelseitige Klebeband paßgenau, also ebenfalls nicht überlappend abgelangt werden kann, da das verwendete Schneidelement ebenfalls achsparallel zu dem Druckzylinder ausgerichtet ist.The teaching according to the invention ensures that a plurality of double-sided adhesive tape rolls are arranged abutting one abutment on a common shaft, and when the double-sided adhesive tape is removed from each roll it is ensured that these are applied abutting the abutting area on the printing cylinder without a gap is formed or an overlap occurs; Because the double-sided adhesive tape rolls can be arranged on a shaft running axially parallel to the longitudinal axis, that is to say the shaft of the printing cylinder, an aligned alignment is possible. It is also ensured that the double-sided adhesive tape can be cut to length, ie also not overlapping, since the cutting element used is also aligned axially parallel to the printing cylinder.
Alternativ kann Bahn für Bahn an Klebeband auf dem Zylinder aufgebracht werden, wobei z.B. eine Klebεbandrolie entlang einer Welle verschiebbar und sodann positionierbar ist.Alternatively, web by web can be applied to the cylinder with adhesive tape, e.g. an adhesive tape roll can be moved along a shaft and then positioned.
Mittels des Anpresselementes ist sichergestellt, daß das doppelseitige Klebeband stets die erfoidei li he Vorspannung ei fahrt, um faltenfiei auf den Druckz\ linder aufgeklebt zu werden Hierzu kann das Anpresselement w ie -iolle in einer schhtzfoi mi en Aufnahme linder das Klebeband gefuhrt w ird, so daß dieses eine Vorspannung in Richtung des lιnders erfahrt. Ein Verschwenken in Richtung des Zy linders und Anpressen mittels z B linder ist gleichfalls möglichBy means of the pressing element it is ensured that the double-sided adhesive tape always travels the required preload in order to be glued onto the pressure cylinder in a wrinkle-free manner. For this purpose the pressing element can be placed in a protective receptacle the adhesive tape is guided so that this is a pretension in the direction of the countries experience. A pivoting in the direction of the cylinder and pressing by means of z linder is also possible
Des weiteren ist vorgesehen, daß die Halterung Aufnahmen aufweist, wobei in den Aufnahmen die Welle des Diuckzyhndei s abstutzbar ist bzw. die Aufnahmen auf der Welle des Druckzylinders abstutzbar sind.Furthermore, it is provided that the holder has receptacles, wherein the shaft of the Diuckzyhndei s can be supported in the receptacles or the receptacles can be supported on the shaft of the printing cylinder.
Mit anderen Worten besteht die Möglichkeit, zum einen den Druckzylinder bereits in der Druckmaschine bzw. Aufklebegeraten (Klischeemontagegerate) verbleiben zu lassen und sodann die Halterung mit ihrer entsprechenden Aufnahme gegen die Druckzylin- derwelle zum Beispiel hydraulisch anzuheben. Alternativ kann der Druckzylinder mit seiner Welle in einer entsprechenden Aufnahme der Halterung eingelegt werden, um sodann das Klebeband aufzubringenIn other words, it is possible, on the one hand, to leave the printing cylinder already in the printing press or gluing device (plate mounting device) and then to hold the holder with its corresponding receptacle against the printing cylinder. hydraulic shaft, for example. Alternatively, the pressure cylinder with its shaft can be inserted in a corresponding receptacle of the holder in order to then apply the adhesive tape
Die Aufnahmen selbst sollten \ on Seitenwangen der Halterung ausgehen und können vorzugsweise durch pπsmenform ge Aussparungen gebildet werden.The recordings themselves should start on the side cheeks of the holder and can preferably be formed by pπsmenform cutouts.
Eine besonders einfache Konstruktion ergibt sich dann, wenn jede Seitenwange einen ersten Aufnahmeschlitz für die Rolle des doppelseitigen Klebebandes bzw. eine diese aufnehmende Welle und einen zweiten Aufnahmeschlitz für das als Anpressrolle ausgebildete Anpresselement aufweist. Dabei \ erlauft der zweite Schlitz in Richtung der Welle des Druckzylinders, so daß infolgedessen die Anpressrolle stets das Bestreben zeigt, innerhalb des zweiten Schlitzes in Richtung des Druckzylinders zu gleiten, so daß das Doppelklebeband die eifoiderhche Vorspannung ei fahrt.A particularly simple construction results when each side cheek has a first receiving slot for the roll of the double-sided adhesive tape or a shaft receiving it and a second receiving slot for the pressing element designed as a pressing roller. Here \ runs the second slot in the direction of the shaft of the printing cylinder, so that consequently the pressure roller always shows the effort to slide within the second slot in the direction of the printing cylinder, so that the double-sided tape drives the egg-like pre-tension egg.
Alternativ kann das Anpreßelement mittels Verstellz} linder zur Anlage an den Druckzylinder gebracht w erden.Alternatively, the pressure element can be brought into contact with the pressure cylinder by means of an adjusting cylinder.
Nach einem w eiteren Vorschlag der Eifindung ist \ orgesehen. daß die Voi πchtung eine Aibeitsllache aufweist, entlang der das Klebeband fühlbar ist und auf der der Druck- linder drehbar aufliegt und daß auf den arbensflachenabgew andten Wellenbereich ein Hebelelement einwirkt. Somit erfahrt der Di uckz\ linder eine eindeutige Lagefiλierung. um den Druckzy linder diehen zu können. Hierdurch u n d automatisch das Klebeband auf dei Obei Hache des Dι lmdeιs aufgebracht Sodann ist es nur noch erforderlich, das Klebeband im erfoidei liehen Umfang abzul ngenAnother suggestion of finding is envisaged. that the device has a surface, along which the adhesive tape can be felt and on which the pressure relief device rotates, and that a lever element acts on the shaft area facing away from the surface. Thus, the di uckz \ linder experiences a clear position fixation. to be able to see the printing cylinder. This and automatically the tape on the Obei Hache des Dι lmdeιs applied Then it is only necessary to cut the adhesive tape to the extent required
Von der Arbeitsfläche selbst kann des w eiteren eine Aufnahme für das doppelseitige Klebeband bzw. die diese aufnehmende Welle ausgehen. Die entsprechenden Aufnahmen können als Schenkel oder Seitenwangen ausgebildet sein und sind vorzugsweise zueinander \ erstellbar, um auf die Breite des Druckzylinders angepaßt zu w erden Zusätzlich kann die Welle des doppelseitigen Klebebandes spannbar sein, um das doppelseitige Klebeband beim Abrollen vorzuspannen.Furthermore, a receptacle for the double-sided adhesive tape or the shaft receiving it can emanate from the work surface itself. The corresponding receptacles can be designed as legs or side cheeks and are preferably adjustable to one another in order to be adapted to the width of the printing cylinder In addition, the shaft of the double-sided adhesive tape can be tensioned in order to pretension the double-sided adhesive tape when unrolling.
In Weiterbildung der Erfindung ist vorgesehen, daß sowohl der Druckzvlinder als auch die doppelseitige Klebebandrolle bzw. -rollen bzw. deren Welle jeweils in einer Aufnahme w ie Aufnahmeprisma in Wangen einer Halterung gelagert sind, wobei das Doppelklebeband ebenfalls in Richtung des Druckzylinders eine Vorspannung erfahrt.In a further development of the invention, it is provided that both the printing cylinder and the double-sided adhesive tape roll or rolls or their shaft are each mounted in a receptacle such as a receiving prism in the cheeks of a holder, the double adhesive tape likewise being preloaded in the direction of the printing cylinder.
Insbesondere ist vorgesehen, daß mehrere doppelseitige Klebebandrollen von einer gemeinsamen Welle ausgehen, wobei die doppelseitigen Klebebandrollen Stoß an Stoß auf der Welle angeoidnet sindIn particular, it is provided that a plurality of double-sided adhesive tape rolls originate from a common shaft, the double-sided adhesive tape rolls being anoidally abutted on the shaft

Wegen der Länge der Druckzylinder 10 ist es dabei erforderlich, daß mehrere doppelseitige Klebebandabschnitte nebeneinander auf der Oberfläche 10 des Druckzylinders 12 aufgebracht werden, wobei aufgrund der erfindungsgemäßen Lehre die Klebebandabschnitte lückenlos Stoß an Stoß und an den Enden überlappungsfrei aufgeklebt sind.Fig. 4 shows a \ ated embodiment of a device for applying a double-sided adhesive tape. In the figures, in which basically the same elements are provided with the same reference numerals, various embodiments of devices are shown in side view, with the aid of which a double-sided adhesive tape 14, which is unwound from a roll 16, is to be glued onto the surface 10 of a printing cylinder 12 , in order to then apply a printing plate such as a flexographic cliché to the outside, after a protective paper such as silicone paper has been removed therefrom. Because of the length of the printing cylinder 10, it is necessary for a plurality of double-sided adhesive tape sections to be applied next to one another on the surface 10 of the printing cylinder 12, the adhesive tape sections being adhesively bonded joint-to-joint and without overlap at the ends due to the teaching according to the invention.
In Fig. 1 ist eine Vorrichtung 18 dargestellt, die eine Halterung 20 umfaßt, die zum Beispiel hydraulisch angehoben w ird, um den in dem Andruck- und Montagegerät installierten Druckzylinder 12 bzw. dessen Oberfläche 10 mit dem doppelseitigen Klebeband 14 zu beschichten.In Fig. 1, a device 18 is shown, which comprises a holder 20 which is raised hydraulically, for example, in order to coat the pressure cylinder 12 installed in the pressure and assembly device or its surface 10 with the double-sided adhesive tape 14.
Hierzu weist die Halterung entlang der Stirnflächen 22' des Druckzylinders 12 verlaufende und auf dessen Länge einstellbare Wangen 22 auf. Zum Verstellen können die Wangen 22 entlang einer Kugellagerfuhrung 24 verschoben w erden. Von den Wangen 22 gehl ein Schenkel 26 aus. der eine prismenartige Aufnahme 28 für den Druckzvlinder 12 bzw. dessen Welle 0 aufweist. Hierdurch ist eine eindeutige Plazierung der Halterung 20 zu dem Druckzylinder 12 sichergestellt.For this purpose, the holder has cheeks 22 which run along the end faces 22 'of the pressure cylinder 12 and are adjustable in length. For adjustment, the cheeks 22 can be moved along a ball bearing guide 24. One leg 26 extends from the cheeks 22. which has a prism-like receptacle 28 for the pressure cylinder 12 or its shaft 0. This ensures a clear placement of the holder 20 to the pressure cylinder 12.
Achsparallel zu der prismenartigen Aufnahme 28 und damit zu der Welle 30 des Druckzylinders 12 verläuft eine Aufnahme 32. in der eine Welle 34 gelagert ist, auf der eine oder mehrere Klebebandrollen 16 Stoß an Stoß angeordnet sind. Die Aufnahme 32 geht dabei von einem ersten Schlitz 36 aus. um eine sichere Lagerung beim Abziehen des Doppelklebebandes 14 zu ermöglichen. Ungeachtet dessen verläuft aufgrund der erfindungsgemäßen Lehre die Welle 30 des Druckzylinders 12 achsparallel zu der Welle 34 der Klebebandrollen 16, so daß infolgedessen mehrere Klebebandrollen und Abschnitte ein- und derselbe Klebebandrolle Stoß an Stoß und damit das von diesen abgezogene Klebeband bündig ineinander übergehend nebeneinander auf der Oberfläche 10 des Druckzylinders 12 aufgeklebt werden können.A receptacle 32 runs parallel to the axis of the prismatic receptacle 28 and thus to the shaft 30 of the printing cylinder 12, in which a shaft 34 is mounted, on which one or more rolls of adhesive tape 16 are arranged abutting one another. The receptacle 32 starts from a first slot 36. to enable secure storage when pulling off the double-sided adhesive tape 14. Regardless of this, due to the teaching according to the invention, the shaft 30 of the printing cylinder 12 runs axially parallel to the shaft 34 of the adhesive tape rolls 16, so that as a result a plurality of adhesive tape rolls and sections of one and the same adhesive tape roll abut one another and thus the adhesive tape peeled off from them merging into one another flush on the Surface 10 of the printing cylinder 12 can be glued.
Damit ein einwandfreies Befestigen des Doppelklebebandes 14 auf der Oberfläche 10 des Durckzylinders 12 sichergestellt ist, ohne daß eine Faltenbildung erfolgt, verläuft das Doppelklebeband 14 zwischen einer Anpressrolle 38 und dem Druckzylinder 12, so daß das Klebeband 14 eine Vorspannung in Richtung des Druckzylinders 12 erfährt. Die Anpressrolle 3S kann dabei in einem zweiten Schlitz 40 schwerkraftbedingt verschiebbar, so daß eine automatische Anpaßung an den Umfang der Doppelbandkleberolle 16 bzw. des Druckzylinders 12 erfolgt, ohne daß ein Nachjustieren erforderlich ist. Alternativ kann die Anpressrolle 38 mittels Stellzylinder (Fig. 4) in Richtung des Druckzylinders verstellt werden.In order to ensure that the double-sided adhesive tape 14 is securely attached to the surface 10 of the pressure cylinder 12 without wrinkling, the double-sided adhesive tape 14 runs between a pressure roller 38 and the printing cylinder 12, so that the adhesive tape 14 is pretensioned in the direction of the printing cylinder 12. The pressure roller 3S can be displaced in a second slot 40 due to gravity, so that an automatic adaptation to the circumference of the double tape adhesive roller 16 or the pressure cylinder 12 takes place without readjustment being necessary. Alternatively, the pressure roller 38 can be adjusted in the direction of the pressure cylinder by means of an actuating cylinder (FIG. 4).
Von den Wangen 22 geht des w eiteren eine Schneideinrichtung 42 mit einem achsparallel zu der Welle 28 des Druckzylinders 12 und damit der Welle 34 der Doppel- klebebandroile 16 verlaufenden Schneidelement 44 aus. um das Doppelklebeband 14 im erforderlichen Umfang ablängen zu können. Das Schneidelement 44 wie Messer erstreckt sich senkrecht von einem Schenkel 46 der Schneideinrichtung 42. in dessen oberer Seile eine rinneni'örmiee Aufnahme 48 v orgesehen ist, in der die Andrückrolle 38 einlegbar ist. Dies ist dann erforderlich, wenn ein neues Doppelklebeband 14 auf die Oberfläche 10 des Druckzylinders 12 geklebt werden soll.Furthermore, a cutting device 42 with a cutting element 44 running axially parallel to the shaft 28 of the printing cylinder 12 and thus the shaft 34 of the double-adhesive tape 16 starts from the cheeks 22. to be able to cut the double-sided adhesive tape 14 to the required extent. The cutting element 44 such as a knife extends perpendicularly from one leg 46 of the cutter 42 in the upper ropes a rinneni 'örmiee recording is esigned v 48 in which the pressure roller can be placed 38th This is necessary if a new double-sided adhesive tape 14 is to be glued to the surface 10 of the printing cylinder 12.
Bei dem Ausführungsbeispiel der Fig. 2 wird der Druckzylinder 12, der in einem Andruck- und Montagegerät liegt, mittels eines Hebelelementes 52 mit einer prismen- artigen Aufnahme 54 für die Welle 30 achsparallel ausgerichtet. Entlang der Arbeitsfläche 56 des Tisches 50 w ird sodann das auf die Oberfläche 10 des Druckzylinders 12 aufzubringende Klebeband 14 geführt. Hierzu geht die Rolle 16 bzw. die diese aufnehmende Welle 34 von einer Wange 58 aus. in der ein Schlitz 60 verlauft, auf dessen Boden die Welle 34 gelagert ist. und zwar achsparallel zum Verlauf der Welle 30 des Druckzylinders 12.In the embodiment of FIG. 2, the pressure cylinder 12, which lies in a pressure and assembly device, is aligned axially parallel by means of a lever element 52 with a prism-like receptacle 54 for the shaft 30. The adhesive tape 14 to be applied to the surface 10 of the printing cylinder 12 is then guided along the working surface 56 of the table 50. For this purpose, the roller 16 or the shaft 34 receiving it starts from a cheek 58. in which a slot 60 runs, on the bottom of which the shaft 34 is mounted. namely axially parallel to the course of the shaft 30 of the printing cylinder 12.
Um die achsparallele Ausrichtung vorzunehmen, wird die Welle 30 des Druckzylinders 12 mittels des Hebels 52 in der prismenformigen Aufnahme 54 lagefixiert. Hierdurch ist sichergestellt, daß beim Drehen des Druckzylinders 12, wodurch das Klebeband 14 auf dessen Oberfläche 10 aufgebracht wird, dessen Welle 30 stets achsparallel zu der Welle 34 des Doppelklebebandes 16 verläuft.In order to carry out the alignment parallel to the axis, the shaft 30 of the pressure cylinder 12 is fixed in position in the prism-shaped receptacle 54 by means of the lever 52. This ensures that when the printing cylinder 12 is rotated, as a result of which the adhesive tape 14 is applied to its surface 10, its shaft 30 always runs axially parallel to the shaft 34 of the double-sided adhesive tape 16.
Von dem Tisch 50 geht des weiteren eine Schneideinπchtung 66 mit einem parallel zu der Welle 34 der Doppelklebebandrolle 16 und damit zur Welle 30 des Druckzylinders 12 verlaufende Schneidelement w ie Messer 68 aus. Die Schneideinπchtung 66 kann um eine Achse 70 \ erschw enkt w erden, um die der Hebei 52 drehbar ist.Furthermore, a cutting device 66 with a cutting element parallel to the shaft 34 of the double-sided adhesive tape roll 16 and thus to the shaft 30 of the printing cylinder 12 extends from the table 50, such as a knife 68. The cutting device 66 can be swiveled about an axis 70 about which the lifting device 52 can be rotated.
Das Ausfuhrungsbeispiel der Fig. 3 entspricht \ om prinzipiellen Aufbau dem der Fig. 1 mit der Einschr nkung, als daß in einer Halterung 72 bzw . deren Seitenw angen 74 sowohl die Welle 34 der Doppelklebebandrolle 16 als auch die Welle 30 des Druck- lιnders 12 eingesetzt w eiden. Hierzu sind in den Seitenw angen 74 pπsmenformige Aufnahmen 76. 78 v orgesehen, die achsparallel zueinander \ eι laufen. In die Aufnahmen 76. 78 können nicht naher bezeichnete Rollen hineinragen, um die Wellen 30. 34 reibungsmindernd abzustutzen. Dies kann selbstverst ndlich auch für die Ausfuhrungsformen der Fig. 1 und 2 gelten.3 corresponds to the basic structure of that of FIG. 1 with the restriction that in a holder 72 or. whose side walls 74 both the shaft 34 of the double-sided tape roll 16 and the shaft 30 of the pressure changer 12 are used. For this purpose, 74 p-shaped receptacles 76, 78 are provided in the side walls, which run axially parallel to one another. Rollers, not specified in more detail, can protrude into the receptacles 76, 78 in order to support the shafts 30, 34 to reduce friction. This can of course also apply to the embodiments of FIGS. 1 and 2.
Das von der Doppelklebebandrolle 16 abgezogene Doppelklebeband 14 erfahrt -w ie bei dem Ausfuhrungsbeispiel der Fig. 1 - mittels einer in einem Schlitz SO verstellbaren Anpressrolle 82 die erforderlich Vorspannung zum faltenfreien Aufliegen auf der Oberfläche 10 des Druckzv linders 12. Von den Wangen 74 geht des weiteren eine Schneideinrichtung 84 aus. um achsparallel zu der Welle 30 das Klebeband 14 abschneiden zu können.The double-sided adhesive tape 14 pulled off the double-sided adhesive tape roll 16 experiences - as in the exemplary embodiment in FIG. 1 - by means of a pressing roller 82 adjustable in a slot SO the pretension required for it to lie wrinkle-free on the surface 10 of the pressure sensor 12. A cutting device 84 also extends from the cheeks 74. in order to be able to cut the adhesive tape 14 parallel to the shaft 30.
In Fig. 4 ist eine weitere Ausführungsform einer Anordnung dargestellt, mit Hilfe der auf einen Druckzylinder 12 ein doppelseitiges Klebeband 14 faltenfrei und nicht überlappend aufgebracht wird. Hierzu wird das Klebeband 16 von einer Rolle auf die Oberfläche des Druckzylinders 12 aufgebracht, wobei auf das Klebeband 14 eine Spannrolle 86 wirkt, die mittels nicht näher bezeichneter Verstell- wie Druckzylinder derart auf das Klebeband 14 einwirkt, daß dieses sich faltenfrei auf die Oberfläche des Druckzylinders 12 auflegt.4 shows a further embodiment of an arrangement with the aid of which a double-sided adhesive tape 14 is applied to a printing cylinder 12 without creases and not overlapping. For this purpose, the adhesive tape 16 is applied from a roll to the surface of the printing cylinder 12, with a tensioning roller 86 acting on the adhesive tape 14, which acts on the adhesive tape 14 by means of adjusting and printing cylinders, not specified, in such a way that the adhesive tape 14 wrinkles-free on the surface of the Printing cylinder 12 hangs up.
Bei dem Klebeband 16 kann es sich um mehrere auf einer Welle aneinandergereihte Einzelrollen oder um eine einzige Rolle handeln, welche entlang der Welle verstellt wird, um so Streifen \ on Klebeband Stoß an Stoß auf der Oberfläche des Druckzylinders 12 aufzubringen. The adhesive tape 16 can be a plurality of individual rolls lined up on a shaft or a single roll which is adjusted along the shaft so as to apply strips of adhesive tape to the surface of the printing cylinder 12 one after the other.
