Definitions

  • the present invention relates to paper sheets or webs with removable self-adhesive labels and, in particular, to a novel method for producing such paper sheets or webs, in which a pressure-sensitive adhesive and a release paper are applied to a running paper web, at least in the area of the label, and the labels are passed through Paper web are punched out by a punching device.

  • Punching is extremely problematic and delicate with the method described last. Setting up and dressing the corresponding punching device is complex and time-consuming and, moreover, difficult to keep constant over a longer period of time. In order to get the punching under control from a manufacturing point of view, thicker and therefore more expensive release papers than required for the intended use per se must be used.

Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft Papierbögen oder -bahnen mit heraustrennbaren Selbstklebe-Etiketten sowie insbesondere ein neuartiges Verfahren zur Herstellung solcher Papierbögen- oder -bahnen, bei welchem auf eine laufende Papierbahn zumindest im Bereich der Etikette ein Haftkleber und ein Trennpapier aufgebracht und die Etiketten beim Durchlauf der Papierbahn durch eine Stanzvorrichtung ausgestanzt werden. Die Erfindung betrifft schliesslich auch noch eine Vorrichtung zur Durchführung dieses Verfahrens.The present invention relates to paper sheets or webs with removable self-adhesive labels and, in particular, to a novel method for producing such paper sheets or webs, in which a pressure-sensitive adhesive and a release paper are applied to a running paper web, at least in the area of the label, and the labels are passed through Paper web are punched out by a punching device. Finally, the invention also relates to a device for performing this method.

STAND DER TECHNIKSTATE OF THE ART

In der EP-B1-0175719 werden eingangs mehrere Verfahren zur Herstellung von Papierbögen oder Papierbahnen, insbesondere von Formularen, mit heraustrennbaren Selbstklebe-Etiketten beschrieben, die im Bereich der Etiketten eine unerwünscht grosse Dicke aufweisen und/oder bei welchen die Gefahr besteht, dass unter Wärme- oder Druckeinwirkung Haftkleber über den Bereich der Etiketten hinaus in die umliegende Randzone austritt, was zu einem Verkleben führen kann.EP-B1-0175719 initially describes several processes for the production of paper sheets or paper webs, in particular of forms, with removable self-adhesive labels which have an undesirably large thickness in the area of the labels and / or in which there is a risk that under Heat or pressure exposure pressure sensitive adhesive leaks beyond the area of the label into the surrounding edge zone, which can lead to sticking.

Bei den Verfahren gemäss der EP-B1-0175719 werden diese Nachteile zwar vermieden; die Etiketten werden dabei jedoch nicht vollständig aus der Papierbahn ausgestanzt, sondern bleiben über Schwächungslinien, wie z.B. Perforationen, mit der Papierbahn verbunden.These disadvantages are avoided in the methods according to EP-B1-0175719; however, the labels are not completely punched out of the paper web, but remain connected to the paper web via weakening lines, such as perforations.

Bei einem ähnlichen Verfahren, das in der Praxis konkret angewendet wird, werden auf eine Papierbahn im Bereich der Etiketten zunächst eine Haftklebeschicht und Trennpapierstücke aufgebracht. Erst nachfolgend werden die Etiketten ausgestanzt, wobei durch die Papierbahn und die Haftklebeschicht durchgestanzt (Nass-Durchstanzen), das Trennpapier auf der Rückseite der Papierbahn jedoch lediglich angestanzt wird. Die Etiketten bleiben dabei in der Papierbahn fixiert, weil die Haftklebeschicht und die Trennpapierstücke die Etiketten flächenmässig allseitig etwas überragen. Indem die Trennpapierstücke ihrerseits allseitig die Haftklebeschicht etwas überragen, wird vermieden, dass Haftkleber über den Bereich des Trennpapiers hinaus austreten und zu einem Verkleben führen kann.In a similar method that is used in practice, a layer of pressure-sensitive adhesive and pieces of release paper are first applied to a paper web in the area of the labels. Only then are the labels punched out, punched through the paper web and the pressure-sensitive adhesive layer (wet punching), but the release paper on the back of the paper web is merely punched out. The labels remain fixed in the paper web because the pressure-sensitive adhesive layer and the pieces of release paper protrude slightly from the labels on all sides. By the projecting pieces of release paper in turn projecting slightly beyond the pressure-sensitive adhesive layer, it is avoided that pressure-sensitive adhesives can escape beyond the area of the release paper and lead to sticking.

Äusserst problematisch und delikat bei dem zuletzt beschriebenen Verfahren ist das Anstanzen. Das Einrichten und Zurichten der entsprechenden Stanzvorrichtung ist aufwendig und zeitraubend und überdies schwierig über einen längeren Zeitraum konstant zu halten. Um das Anstanzen fertigungstechnisch überhaupt in den Griff zu bekommen, müssen dickere und somit teurere Trennpapiere als für den Gebrauchszweck an sich erforderlich verwendet werden. Dickere Trennpapiere führen vor allem zu einer grösseren Gesamtdicke der Papierbögen- oder bahnen im Bereich der Etiketten, was deren Handhabung beim Stapeln, Rollen oder Beschriften erschwert.Punching is extremely problematic and delicate with the method described last. Setting up and dressing the corresponding punching device is complex and time-consuming and, moreover, difficult to keep constant over a longer period of time. In order to get the punching under control from a manufacturing point of view, thicker and therefore more expensive release papers than required for the intended use per se must be used. Thicker release papers lead above all to a greater total thickness of the paper sheets or webs in the area of the labels, which makes their handling when stacking, rolling or labeling difficult.

Das Anstanzen wird auch durch die vorgängige Beschichtung mit dem Haftkleber erschwert. Der in den allermeisten Fällen eingesetzte wässrige Acrylkleber feuchtet die Papierbahn an, was eine Reduktion der Stanzleistung zur Folge hat. Abhilfe kann hier zwar eine Vortrockung schaffen, doch ist diese aufwendig, energiefressend und gefährdet zudem die Planlage der Papierbahn. Ein Laserprinterdurchlauf beim Kunden kann dadurch erschwert oder unmöglich gemacht werden.Punching is also made more difficult by the previous coating with the pressure sensitive adhesive. The aqueous acrylic adhesive used in the vast majority of cases moistens the paper web, which results in a reduction in the punching performance. This can be remedied by pre-drying, but this is complex, energy-consuming and also jeopardizes the flatness of the paper web. A laser printer run at the customer can be made difficult or impossible.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist insbesondere Aufgabe der vorliegenden Erfindung, ein einfaches und wirtschaftliches Verfahren zur Herstellung von Papierbögen oder -bahnen mit integrierten, jedoch voll ausgestanzten Selbstklebe-Etiketten der eingangs genannten Art anzugeben, das die vorerwähnten Nachteile vermeidet und unter Verwendung von wesentlich dünnerem Trennpapier ausführbar ist. Zudem soll eine zur Durchführung des Verfahrens geeignete Vorrichtung angegeben werden.It is a particular object of the present invention to provide a simple and economical process for the production of paper sheets or webs with integrated but fully die-cut self-adhesive labels of the type mentioned at the outset, which avoids the aforementioned disadvantages and can be carried out using considerably thinner release paper. In addition, a device suitable for carrying out the method is to be specified.

Das erfindungsgemäss Verfahren ist in Anspruch 1 gekennzeichnet. Die Ansprüche 2 bis 10 betreffen vorteilhafte Ausgestalungen dieses Verfahrens.The method according to the invention is characterized in claim 1. Claims 2 to 10 relate to advantageous embodiments of this method.

Bei dem erfindungsgemässen Verfahren ist das Stanzen demnach ein Trocken-Durchstanzen, welches nur an der Papierbahn vor dem Aufbringen des Haftklebers und des Trennpapiers ausgeführt wird. Der Haftkleber wird erst nachfolgend zusammen mit dem Trennpapier auf die Papierbahn aufgebracht. Die ausgestanzten, d.h. mit der Papierbahn nicht mehr verbundenen Etiketten werden in der Papierbahn an ihrem ursprünglichen Ort solange fixiert, bis diese Fixierung durch das mit dem Haftkleber beschichtete Trennpapier übernommen wird.In the method according to the invention, the punching is therefore a dry punching, which is carried out only on the paper web before the pressure sensitive adhesive and the release paper are applied. The pressure sensitive adhesive is only subsequently applied to the paper web together with the release paper. The punched out, i.e. Labels that are no longer connected to the paper web are fixed in their original position in the paper web until this fixing is carried out by the release paper coated with the pressure-sensitive adhesive.

Das Ausstanzen erfolgt gemäss der Erfindung nicht im fertigen, sogenannten Haftkleberlaminat, sondern per Durchstanzen allein in der Papierbahn, bevor diese mit Haftkleber und Trennpapier zusammengeführt wird.According to the invention, the punching is not carried out in the finished, so-called pressure-sensitive adhesive laminate, but rather by punching through the paper web alone before it is brought together with pressure-sensitive adhesive and release paper.

Das erfindungsgemässe Verfahren ermöglicht die Herstellung von Selbstklebe-Etiketten auf Trennpapieren mit wesentlich dünneren Stärken als bisher. So lassen sich z.B. Silikonpapiere von den bisher üblichen 80 g/m2 oder zumindest 50 g/m2 auf lediglich 30g/m2 reduzieren. Die Stärke silikonisierter Folien lässt sich von 50µ auf 20 bis 25µ reduzieren.The method according to the invention enables the production of self-adhesive labels on release papers with considerably thinner thicknesses than previously. So the user can select silicone papers from the usual 80 g / m 2 or at least 50 g / m 2 to only 30 g / m 2 reduced. The thickness of siliconized foils can be reduced from 50µ to 20 to 25µ.

Mit dem erfindungsgemässen Verfahren lassen sich höhere Produktionsgeschwindigkeiten erreichen und vor allem die Einrichtzeiten der Produktionsmaschinen wesentlich verkürzen.With the method according to the invention, higher production speeds can be achieved and, above all, the set-up times of the production machines can be significantly reduced.

Die Fixierung der ausgestanzten Etiketten in der Papierbahn zwischen dem Austanzen und dem Aufbringen des Haftklebers bzw. Trennpapiers erfolgt vorzugsweise elektrostatisch oder vakuumtechnisch und zwar entweder auf einem der Zylinder der Stanzvorrichtung oder einem mit der Papierbahn sich mitbewegenden Endlos-Förderband.The punched-out labels are preferably fixed in the paper web between the punching out and the application of the pressure-sensitive adhesive or release paper, preferably by electrostatic or vacuum technology, either on one of the cylinders of the punching device or on an endless conveyor belt which moves with the paper web.

Das Trennpapier wird vorzugsweise von einer Rolle abgezogen. Das Trennpapier kann bereits auf der Rolle mit dem Haftkleber beschichtet sein. Die Beschichtung mit dem Haftkleber kann jedoch ebenfalls erst unmittelbar vor dem Aufbringen auf die Papierbahn erfolgen.The release paper is preferably pulled off a roll. The release paper can already be coated on the roll with the pressure sensitive adhesive. However, the coating with the pressure sensitive adhesive can also only be carried out immediately before being applied to the paper web.

Die Papierbahn kann ganzflächig mit dem Trennpapier laminiert werden, was dann von Vorteil ist, wenn man praktisch nur Selbstklebeetiketten herstellen möchte. Das Trennpapier kann andererseits vor dem Aufbringen auf die Papierbahn auf lediglich etwa die Grösse der Etiketten zugeschnitten werden. Dies empfiehlt sich z.B. bei Formularen, die in einer grösseren Papierfläche nur eine einzelne, vergleichsweise kleine Etikette enthalten.The entire surface of the paper web can be laminated with the release paper, which is an advantage if you only want to produce self-adhesive labels. The release paper, on the other hand, can be cut to only about the size of the labels before being applied to the paper web. This is recommended e.g. for forms that contain only a single, comparatively small label in a larger paper area.

Der Haftkleber wird nach der Erfindung zusammen mit dem Trennpapier aufgebracht. Nachfolgend muss er sich jedoch so gut mit dem Etikettenmaterial verbinden, dass er auf der Etikettenrückseite haftet, wenn diese bei Gebrauch abgezogen wird. Es soll nach dem Abziehen der Etikette kein Haftkleber mehr auf dem Trennpapier im Bereich der Etikette zurückbleiben. Dieser sogenannte Haftklebertransfer kann durch Druckausübung beim Aufbringen des Trennpapiers unterstützt und beschleunigt werden. Wenn die Papierbahn z.B. in einer Stanzvorrichtung mit einem rotierenden Stanzzylinder um diesen umgelenkt wird und das Aufbringen des Trennpapiers ebenfalls auf dem Stanzzylinder erfolgt, dann üben die Stanzmesser des Stanzzylinders an den Schnittkanten der Etiketten einen erhöhten Druck aus, der sich, wie erläutert, günstig auf den Haftklebertransfer auswirkt. Der dabei ausgeübte Druck ist allerdings viel geringer als der beim Stanzen, so dass keine Probleme wie z.B. beim Anstanzen auftreten.The pressure sensitive adhesive is applied according to the invention together with the release paper. Subsequently, however, it must bond to the label material so well that it sticks to the back of the label if it is peeled off in use becomes. After the label has been removed, there should be no pressure-sensitive adhesive left on the release paper in the area of the label. This so-called pressure-sensitive adhesive transfer can be supported and accelerated by applying pressure when applying the release paper. If, for example, the paper web is deflected in a punching device with a rotating punching cylinder and the release paper is also applied to the punching cylinder, the punching knives of the punching cylinder exert an increased pressure on the cut edges of the labels, which, as explained, is favorable affects the pressure sensitive adhesive transfer. However, the pressure exerted is much lower than that during punching, so that no problems such as punching occur.

Die erfindungsgemässe Vorrichtung ist in Anspruch 11 gekennzeichnet, wobei die Ansprüche 12 bis 18 bevorzugte Ausgestaltungen dieser Vorrichtung betreffen.The device according to the invention is characterized in claim 11, claims 12 to 18 relating to preferred embodiments of this device.

Ein nach dem erfindungsgemässen Verfahren hergestellter Papierbogen oder eine entsprechende Papierbahn mit mindestens einer heraustrennbaren Etikette ist schliesslich in Anspruch 19 gekennzeichnet, wobei Anspruch 20 wiederum eine bevorzugte Ausführungsform mit einem extrem dünnen und nur sehr wenig auftragenden Trennpapier angibt. Charakteristisch ist, dass das Trennpapier sowie der Haftkleberauftrag keinerlei Stanzspuren aufweisen.A sheet of paper produced by the method according to the invention or a corresponding paper web with at least one label that can be removed is finally characterized in claim 19, claim 20 again specifying a preferred embodiment with an extremely thin and only very little releasing paper. It is characteristic that the release paper and the pressure sensitive adhesive application show no punch marks.

Die Figuren 2 bis 4 zeigen drei verschiedene Vorrichtung zur Ausführung des erfindungsgemässen Verfahrens zur Herstellung solcher Bögen respektive Formulare in drei unterschiedlichen Varianten. In den Figuren sind übereinstimmende Teile mit den gleichen Bezugszeichen versehen.The invention will be explained in more detail below on the basis of exemplary embodiments in connection with the figures. In Fig. 1, a single sheet of paper or a form with a removable self-adhesive label is shown in supervision and in two sections. FIGS. 2 to 4 show three different devices for executing the method according to the invention for producing such sheets or forms in three different variants. In parts in the figures are provided with the same reference numerals.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

Zunächst wird auf Fig. 1 bezug genommen. Diese zeigt unter a) ein mit einer Randlochung versehenes Formular 1 aus einem Papiermaterial mit einer aus diesem heraustrennbaren Etikette 2. Wie sich in der geschnittenen Darstellung unter b) (Schnitt A-A in Fig. 1a) ersehen lässt, ist die Etikette 2 im Formular 1 durch ein rückseitig auf dieses aufgeklebtes, die Etikette 2 randseitig allseitig überragendes Trennpapierstück 3 fixiert. Mit 4 ist in Fig. 1 jeweils eine Haftklebeschicht bezeichnet, welche die Etikette ebenfalls randseitg allseitig überragt, flächenmässig jedoch etwas kleiner als das Trennpapierstück 3 ist. Der Haftkleber der Haftklebeschicht 4 weist am Papier des Formulares 1 bzw. der Etikette 2 eine grössere Haftung auf als am Trennpapier 3. Die Haftklebeschicht rückseitig der Etikette 2 löst sich demzufolge zusammen mit der Etikette bei deren Ablösung vom Trennpapier 3 ab, wie dies Fig. 1c) zeigt.First, reference is made to FIG. 1. This shows under a) a form 1 provided with a perforation at the edge from a paper material with a label 2 that can be removed therefrom. As can be seen in the sectional illustration under b) (section AA in FIG. 1a), the label 2 in form 1 is fixed by a piece of separating paper 3 glued to the rear of the label 2 and projecting from all sides on the edge. 1 in FIG. 1 denotes a pressure-sensitive adhesive layer, which also extends beyond the label on all sides, but is somewhat smaller in area than the release paper piece 3. The pressure-sensitive adhesive of the pressure-sensitive adhesive layer 4 has greater adhesion to the paper of the form 1 or the label 2 than to the release paper 3. The pressure-sensitive adhesive layer on the back of the label 2 consequently detaches from the release paper 3 when the label is detached, as shown in FIG. 1c) shows.

Bei der Vorrichtung von Fig. 2 läuft eine Papierbahn 5 von einer Rolle 6 zunächst zwischen einem Stanzzylinder 7 und einem Gegenstandszylinder 8 einer Stanzvorrichtung 9 durch. Dabei werden die gewünschten Etiketten 2 aus der Papierbahn 5 ausgestanzt. Nach dem Stanzen weisen die Etiketten 2 keinerlei Verbindung mehr mit der Papierbahn 5 auf. Von einer weiteren Rolle 10 wird eine Trennpapierbahn 11 (z.B. ein Silikonpapier oder auch eine Trennfolie) abgezogen und in einer Beschichtungsstation 12 mit einem Haftkleber 4 selektiv beschichtet. Mittels einer Schneidvorrichtung 13 werden von der Trennpapierbahn 11 einzelne, mit Haftkleber beschichtete Trennpapierstücke 3 abgeschnitten. Die beschichteten Trennpapierstücke 3 werden nachfolgend in einer Laminierungsvorrichtung 14 auf die Papierbahn 5 im Bereich der Etiketten 2 auflaminiert. Die Laminierungsvorrichtung 14 umfasst hier einerseits den bereits erwähnten Stanzzylinder 7 der Stanzvorrichtung 9 sowie einen Laminierungszylinder 15.In the device of FIG. 2, a paper web 5 from a roll 6 first runs between a punch cylinder 7 and an object cylinder 8 of a punch device 9. The desired labels 2 are punched out of the paper web 5. After punching, the labels 2 no longer have any connection with the paper web 5. A release paper web 11 (for example a silicone paper or also a release film) is drawn off from a further roll 10 and selectively coated with a pressure sensitive adhesive 4 in a coating station 12. By means of a cutting device 13, individual pieces of release paper 3 coated with pressure sensitive adhesive are cut off from the release paper web 11. The coated release paper pieces 3 are subsequently laminated onto the paper web 5 in the area of the labels 2 in a laminating device 14. The lamination device 14 here comprises, on the one hand, the already mentioned punch cylinder 7 of the punch device 9 and a lamination cylinder 15.

Damit die beim Durchlauf zwischen dem Stanzzylinder 7 und dem Gegenstandszylinder 8 aus der Papierbahn 5 ausgestanzten Etiketten 2 bei der Weiterbewegung der Papierbahn 5 an ihrer ursprünglichen Stelle in der Papierbahn 5 verbleiben, bis sie durch die auflaminierten Trennpapierstücke 3 dort fixiert werden, werden sie vorübergehend auf dem Stanzzylinder 7 fixiert. Eigens zu diesem Zweck wird die Papierbahn 5 um diesen herum umgelenkt. Nach nur etwa einer Viertelumdrehung auf dem Stanzzylinder 7 werden die Trennpapierstücke 3 bereits über den Laminierungszylinder 15 zugeführt. Dem Stanzzylinder 7 kommt dann auch noch die Aufgabe zu als Gegendruckzylinder beim Laminierungsvorgang zu wirken. Die kurzfristige Fixierung auf dem Stanzzylinder 7 erfolgt insbesondere elektrostatisch, wobei die statische Elektrizität hierzu mittels der Elemente 16 erzeugt wird. Zur vakuumtechnischen Fixierung müsste der Stanzzylinder mit Vakuumsauglöchern von ca 1 - 3 mm Durchmesser versehen sein, welche periodisch auf Saugen und Loslassen angesteuert werden.So that the labels 2 punched out of the paper web 5 during the passage between the punch cylinder 7 and the object cylinder 8 remain in their original position in the paper web 5 during the further movement of the paper web 5 until they are fixed there by the laminated release paper pieces 3, they are temporarily opened the punch cylinder 7 fixed. For this purpose, the paper web 5 is deflected around it. After only about a quarter turn on the punch cylinder 7, the release paper pieces 3 are already fed through the lamination cylinder 15. The punch cylinder 7 then also has the task of acting as an impression cylinder in the lamination process. The short-term fixation on the punch cylinder 7 takes place, in particular, electrostatically, the static electricity being generated for this purpose by means of the elements 16. For vacuum-technical fixation, the punching cylinder would have to be provided with vacuum suction holes of approx. 1 - 3 mm in diameter, which are periodically activated by suction and release.

Im Beispiel von Fig. 2 wird die Papierbahn 5 um den Stanzzylinder 7 um 180° umgelenkt. Grundsätzlich wäre jedoch bereits ein kleinerer Umlenkwinkel ausreichend, wobei dieser allerdings von der Grösse der Etiketten und dem Durchmesser des Stanzzylinders abhängt.In the example of FIG. 2, the paper web 5 is deflected around the punching cylinder 7 by 180 °. In principle, however, a smaller deflection angle would be sufficient, although this depends on the size of the labels and the diameter of the punch cylinder.

Die Umlenkung der Papierbahn 5 und die Fixierung der Etiketten 2 könnte auch um bzw. auf dem Gegenstandszylinder 8 erfolgen. Die diesbezügliche Verwendung des Stanzzylinders 7 hat jedoch den Vorteil, dass im Augenblick des Auflaminierens der beschichteten Trennpapierstücke 3 die Messerkanten des Stanzzylinders für einen gewissen zusätzlichen Laminierungsdruck im Randbereich der Etiketten bewirken, der sich günstig auf den Transfer des Haftklebers vom Trennpapier auf die Etiketten auswirkt.The deflection of the paper web 5 and the fixing of the labels 2 could also take place around or on the object cylinder 8. The use of the punch cylinder 7 in this regard has the advantage, however, that at the moment the coated release paper pieces 3 are laminated on, the knife edges of the punch cylinder cause a certain additional lamination pressure in the edge area of the labels, which is favorable affects the transfer of the adhesive from the release paper to the labels.

In Fig. 2 sind mit 17 noch ein Endlos-Förderband für die Zuführung der Trennpapierbahn 11 sowie mit 18 eine Trocknungsvorrichtung für den Haftkleberauftrag auf der Trennpapierbahn 11 bezeichnet. Das Endlos-Förderband 17 wird vorzugsweise relativ zur Bewegung der Papierbahn 5 so gesteuert, dass die Trennpapierstücke 3 exakt richtig auf dieser im Bereich der ausgestanzten Etiketten 2 zu liegen kommen.In FIG. 2, 17 is also an endless conveyor belt for feeding the release paper web 11 and 18 a drying device for applying adhesive on the release paper web 11. The endless conveyor belt 17 is preferably controlled relative to the movement of the paper web 5 in such a way that the separating paper pieces 3 come to lie exactly on the latter in the area of the punched-out labels 2.

Bei der Vorrichtung von Fig. 3 entfällt die Beschichtungsstation 12 und die Trocknungsvorrichtung 18, da hier die Trennpapierbahn bereits auf der Rolle 10 mit dem Haftkleber 4 beschichtet ist. Die Haftkleberbeschichtung ist nicht durchgehend, sondern, wie bereits bei Fig. 2, selektiv unterbrochen. Die Trennpapierstücke 3 können dadurch auf den Formularen die Haftklebeschichten flächenmässig etwas überragen. Auch muss die Schneidvorrichtung 13 nicht durch den Haftkleber mit durchschneiden. Ansonsten bestehen keine Unterschiede zwischen Fig. 2 und Fig. 3.3, the coating station 12 and the drying device 18 are dispensed with, since here the release paper web is already coated with the pressure-sensitive adhesive 4 on the roll 10. The pressure sensitive adhesive coating is not continuous, but rather, as in FIG. 2, selectively interrupted. The release paper pieces 3 can thus slightly protrude the pressure-sensitive adhesive layers on the forms. The cutting device 13 also does not have to cut through with the pressure sensitive adhesive. Otherwise there are no differences between FIGS. 2 and 3.

In Fig. 4 erfolgt die zeitweilige Fixierung der Etiketten 2 nicht auf einem der Zylinder der Stanzvorrichtung 9 sondern auf einem extra zu diesem Zweck vorgesehenen Endlos-Förderband 19. Dieses ist am Zylinder 8 der Stanzvorrichtung um eine Rolle 20 mit einem gegenüber dem Zylinder 8 sehr kleinen Durchmesser umgelenkt, um die Etiketten 2 bereits übernehmen zu können, solange diese noch nicht vollständig aus der Papierbahn ausgestanzt sind. Der Abstand zwischen der Rolle 20 und der Engstelle zwischen den beiden Zylindern 7 und 8 der Stanzvorrichtung 9 sollte also kleiner als die Ausdehnung der Etiketten 2 in Längsrichtung der Papierbahn 5 sein. Die Fixierung der Etiketten auf dem Endlos-Förderband 19 erfolgt wieder elektrostatisch. Auch in Fig. 4 ist die Trennpapierbahn 11 bereits auf der Rolle 10 mit Haftkleber vorbeschichtet. Der Haftkleberauftrag ist hier allerdings kontinuierlich und weist keine Lücken auf wie in Fig. 3. Die Vorrichtungen von Fig. 2 und Fig. 3 könnten natürlich ebenfalls mit einem kontinuierlichen Haftkleberauftrag auf der Trennpapierbahn betrieben werden.4, the temporary fixation of the labels 2 does not take place on one of the cylinders of the punching device 9 but on an endless conveyor belt 19 specially provided for this purpose deflected small diameter in order to be able to take over the labels 2 as long as they have not yet been completely punched out of the paper web. The distance between the roll 20 and the constriction between the two cylinders 7 and 8 of the punching device 9 should therefore be smaller than the extent of the labels 2 in the longitudinal direction of the paper web 5. The labels are again fixed electrostatically on the endless conveyor belt 19. 4, the release paper web 11 is already precoated on the roll 10 with pressure sensitive adhesive. However, the pressure sensitive adhesive application is continuous here and has no gaps as in Fig. 3. The devices of Fig. 2 and Fig. 3 could of course also be operated with a continuous pressure sensitive adhesive application on the release paper web.

Schlussendlich muss zur Herstellung von Einzelbögen oder Einzelformularen aus der Papierbahn 5 diese natürlich noch geeignet beschnitten werden, was in den Figuren allerdings nicht mehr dargestellt ist. Die Papierbahn kann also solche aber auch belassen werden.Finally, for the production of single sheets or single forms from the paper web 5, these must of course still be suitably trimmed, which is however no longer shown in the figures. However, the paper web can also be left as such.
