Abstract

In methods used thus far for preparing replacement reels of web material to be printed, which are to be clamped into an automatic reel changer of a rotary printing machine, it is not guaranteed that the reel beginning bears against the outer layer of the reel over its entire breadth and that the reel beginning of the new reel is taken along by the residual web running out without at the same time tearing the new web. According to the method according to the invention, an edge (3) running at an angle is cut at the reel beginning (2) and adhesively bonded on the outer layer (8) of the reel (1) over the entire breadth of the reel (1) with a continuous adhesive strip (4) which does not adhere in a perforated central zone (6). Finally, double-sided adhesive strips (10) are arranged on the reel beginning (2) to form a bonding area. The invention can be applied to all reels of any web material to be printed in rotary printing, which are intended for use in automatic reel changers. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Vorbereiten einer Rolle bahnförmigen Bedruckstoffs für eine Verwendung in einer Rotationsdruckmaschine mit automatischem Rollenwechsler.The present invention relates to a method for preparing a roll of web-shaped printing material for use in a rotary printing press with an automatic roll changer.

Bei Rotationsdruckmaschinen wird der Bedruckstoff, zum Beispiel Papier, dem Druckwerk in Form einer Bedruckstoffbahn zugeführt. Dabei wird die Bedruckstoffbahn von einer Rolle abgewickelt, die in einer im folgenden kurz als Rollenwechsler bezeichneten Vorrichtung, die am Papiereinlauf der Druckmaschine angeordnet ist, eingespannt ist. Um die insbesondere im Zeitungsdruck einzuhaltende Bedingung des unterbrechungsfreien Druckens erfüllen zu können, erfolgt das Ersetzen einer abgewickelten Bedruckstoffbahnrolle durch eine neue vorteilhafterweise im fliegenden Wechsel. Dazu weist der Rollenwechsler wenigstens zwei Spannvorrichtungen zur Aufnahme von wenigstens einer unmittelbar abzuwickelnden ersten Bedruckstoffbahnrolle und einer im Anschluß an die erste Rolle abzuwickelnden zweiten Bedruckstoffbahnrolle, eine Vorrichtung zum Antreiben wenigstens einer der Bedruckstoffbahnrollen und eine Vorrichtung zum automatischen Ankleben des Anfangs der zweiten Rolle an das Ende der ersten auf.In rotary printing machines, the printing material, for example paper, is fed to the printing unit in the form of a printing material web. In this case, the printing material web is unwound from a roll, which is clamped in a device, hereinafter referred to briefly as a roll changer, which is arranged at the paper inlet of the printing press. In order to be able to meet the requirement of uninterrupted printing, particularly in newspaper printing, a unwound printing web roll is replaced by a new one, advantageously on the fly. For this purpose, the roll changer has at least two tensioning devices for receiving at least one first printing material web roll to be unwound and a second printing material web roll to be unwound after the first roll, a device for driving at least one of the printing material web rolls and a device for automatically gluing the beginning of the second roll to the end the first on.

Ein zuverlässiges Ankleben des Anfangs der zweiten Rolle an das Ende der ersten Rolle ist jedoch nur möglich, wenn die jeweilige zweite Rolle in geeigneter Weise vorbereitet wird.However, the beginning of the second roll can only be reliably adhered to the end of the first roll if the respective second roll is prepared in a suitable manner.

Aus der EP 0 129 238 ist bekannt, die neue Rolle folgendermaßen vorzübereiten. Zunächst wird - nach erfolgtem Aus-packen der Rolle und Entfernen der beschädigten äußeren Lagen - die Kante der Bahn gerade geschnitten. Dann wird die Kante der Bahn auf der äußeren Lage mittels einer Mehrzahl von Klebestreifen festgeklebt. Die dabei verwendeten Klebestreifen weisen auf der Klebeseite eine in Streifenlängsrichtung verlaufende nichtklebende Mittelzone und rechts und links davon je eine Klebezane auf. Die Klebestreifen werden nach der Rollenkante ausgerichtet und so aufgebracht, daß die Mittelzone auf der Kante der Bahn zu liegen kommt und so die eine Klebezone auf dem Rollenende und die andere Klebezone auf dem daneben liegenden Abschnitt der äußeren Lage klebt.It is known from EP 0 129 238 to prepare the new role as follows. First, after unpacking the roll and removing the damaged outer layers, the edge of the web is cut straight. Then the edge of the web is glued to the outer layer by means of a plurality of adhesive strips. The adhesive strips used have an in on the adhesive side Non-adhesive central zone running in the longitudinal direction of the strip and an adhesive membrane on the right and left of it. The adhesive strips are aligned with the edge of the roll and applied so that the middle zone comes to rest on the edge of the web and so one adhesive zone sticks to the end of the roll and the other adhesive zone sticks to the adjacent section of the outer layer.

Wenn dann die Rolle in den Rollenwechsler eingespannt ist, wird in der Mittelzone des Klebestreifens durch eine entsprechend ausgelegte Vorrichtung eine Perforierung angebracht, um das Aufreißen der Klebestreifen beim Ankleben des Rollenanfangs an die alte Bahn zu erleichtern.When the roll is then clamped in the roll changer, a perforation is made in the central zone of the adhesive strip by means of an appropriately designed device in order to facilitate the tearing open of the adhesive strips when the roll start is glued to the old web.

Das vorstehend beschriebene Verfahren zum Vorbereiten einer neuen Bedruckstoffbahnrolle ist insofern nachteilig, als die Kante der Bahn nur an einigen Stellen auf der äußeren Bedruckstoffbahnlage festgeklebt wird. Dadurch kann sich beim Beschleunigen der neuen Rolle auf die Abwickelgeschwindigkeit der alten Rolle aufgrund der Drehrichtung Luft unter den Rollenanfang der neuen Rolle drücken und so zu einem Abheben des Rollenanfangs von der darunterliegenden Bahnlage führen. Das bedeutet die Gefahr eines unkontrollierbaren Verhaltens der neuen Rolle während des Anklebevorgangs, was u.a. bei exzentrisch laufenden Rollen zu ungewolltem, verfrühtem Ankleben führt, und insbesondere ein nicht über die gesamte Breite der Rolle gleichmäßiges Mitreißen der Bahn im Zeitpunkt der Klebung, was zu einer erhöhten Makulaturerzeugung oder Störung des Druckbetriebs führen kann.The above-described method for preparing a new roll of printing material web is disadvantageous in that the edge of the web is only glued to the outer printing material web layer in some places. As a result, when the new roll is accelerating, the unwinding speed of the old roll can press air under the beginning of the new roll due to the direction of rotation and thus lead to a lifting of the beginning of the roll from the underlying web. This means the risk of uncontrollable behavior of the new roll during the gluing process, which among other things. in the case of eccentrically running rolls leads to unwanted, premature gluing, and in particular the fact that the web is not carried along uniformly over the entire width of the roll at the time of gluing, which can lead to increased waste production or malfunction of the printing operation.

Nachteilig ist ferner, daß das Perforieren der Klebestreifen hinsichtlich der Lage und der Tiefe der Perforierung genau gesteuert werden muß, um einerseits ein Perforieren der Bedruckstoffbahn zu verhindern, um andererseits aber die Klebestreifen vollständig zu perforieren. Außerdem bilden die Klebestreifen mit der Kante der Bedruckstoffbahn Ecken, von denen ausgehend die Bedruckstoffbahn zerreißen kann, wenn beim Klebevorgang nicht alle Klebestreifen gleichmäßig aufgetrennt werden. Gerade in dieser Hinsicht ist es auch als nachteilig anzusehen, daß die Rollenanfangskante im rechten Winkel zur Abwickelrichtung geschnitten ist, denn so müssen alle Perforierungen unbedingt gleichzeitig aufreißen. Widrigenfalls kommt es, wie auch bei den davor genannten Fällen zu einem erhöhten Makulaturaufkommen.Another disadvantage is that the perforation of the adhesive strips must be precisely controlled with regard to the position and depth of the perforation, on the one hand to prevent perforation of the printing material web, but on the other hand to completely perforate the adhesive strips. In addition, the adhesive strips form corners with the edge of the printing material web, from which the printing material web can tear if all the adhesive strips are not separated evenly during the adhesive process. It is precisely in this regard also to be regarded as disadvantageous that the start edge of the roll is cut at right angles to the unwinding direction, because it is imperative that all perforations tear open at the same time. Otherwise, as in the cases mentioned before, there is an increase in waste.

Aufgabe der Erfindung ist es daher, ein Verfahren anzugeben, mit dem eine Materialbahnersatzrolle so für die Verwendung in einem Rollen­wechsler vorbereitet wird, daß auch bei hoher Abwickelgeschwindigkeit gewährleistet ist, daß der Rollenanfang der neuen Rolle sicher und störungsfrei an die auslaufende Restbahn angeklebt wird.The object of the invention is therefore to provide a method with which a material web replacement roll is prepared for use in a roll changer, so that even at high unwinding speed it is ensured that the beginning of the roll of the new roll is glued securely and trouble-free to the remaining web.

Diese Aufgabe wird durch ein Verfahren nach Patentanspruch 1 gelöst.This object is achieved by a method according to claim 1.

Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sind Gegenstand von Unteransprüchen.Advantageous developments of the method according to the invention are the subject of dependent claims.

Weitere Merkmale und Zweckmäßigkeiten der Erfindung ergeben sich aus der Beschreibung eines Ausführungsbeispiels anhand der Figuren. Es zeigen:

  • Fig. 1 eine schematische Darstellung einer Papierrolle, die nach dem erfindungsgemäßen Verfahren vorbereitet worden ist, und
  • Fig. 2 eine schematische Schnittdarstellung des erfindungsgemäß zu verwendenden Klebestreifens
Further features and advantages of the invention result from the description of an embodiment with reference to the figures. Show it:
  • Fig. 1 is a schematic representation of a paper roll that has been prepared by the method according to the invention, and
  • Fig. 2 is a schematic sectional view of the adhesive strip to be used according to the invention

In Fig. 1 ist eine Papierrolle 1 als ein Beispiel für eine Bedruckstoffbahnrolle dargestellt, die in erfindungsgemäßer Weise zum Einsetzen in einen Rollenwechsler einer Rotationsdruckmaschine vorbereitet worden ist. Die an die erste, abgewickelte Papierrolle anzuklebende Papierrolle 1 wird ausgepackt, und es werden die beschädigten Papierlagen abgetragen. Dann wird die Kante 3 des Rollenanfangs 2 unter einem Winkel α zwischen der Abwickelrichtung und der Rollenanfangskante 3 schräg abgeschnitten. Der Winkel α muß kleiner als 90° sein und sollte zweckmäßig zwischen 60° und 80° betragen. Anschließend wird die Rollenanfangskante 3 mit einem die gesamte Breite der Rolle 1 überspannenden, speziell ausgebildeten Klebestreifen 4 auf der darunterliegenden äußeren Papierlage 8 festgeklebt.1 shows a paper roll 1 as an example for a printing material web roll which has been prepared in the manner according to the invention for insertion into a roll changer of a rotary printing press. The paper roll 1 to be glued to the first unwound paper roll is unpacked and the damaged paper layers are removed. Then the edge 3 of the roll start 2 is cut off at an angle α between the unwinding direction and the roll start edge 3. The angle α must be less than 90 ° and should suitably be between 60 ° and 80 ° be. Subsequently, the edge 3 of the roll is glued to the outer paper layer 8 underneath with a specially designed adhesive strip 4 spanning the entire width of the roll 1.

Der erfindungsgemäß zu verwendende Klebestreifen 4 ist in drei Zonen 5, 6, 7 unterteilt (Fig. 2). Von diesen Zonen ist die eine äußere Zone 5 beidseitig selbstklebend, die mittlere Zone 6 nichtklebend und die andere äußere Zone 7 einseitig selbstklebend ausgebildet. Die mittlere Zone 6 ist mit einer in Streifenlängsrichtung verlaufenden Perforierung 9 versehen. Der Klebestreifen 4 wird nun derart aufgebracht, daß die mittlere Zone 6 auf der Kante 3 des Rollenanfangs 2 zu liegen kommt und daß die eine Klebezone 5 auf dem Rollenanfang 2 und die andere Klebezone 7 auf dem angrenzenden Abschnitt 8 der äußeren Papierlage klebt.The adhesive strip 4 to be used according to the invention is divided into three zones 5, 6, 7 (FIG. 2). Of these zones, one outer zone 5 is self-adhesive on both sides, the middle zone 6 is non-adhesive and the other outer zone 7 is self-adhesive on one side. The central zone 6 is provided with a perforation 9 running in the longitudinal direction of the strip. The adhesive strip 4 is now applied in such a way that the central zone 6 comes to rest on the edge 3 of the roll start 2 and that one adhesive zone 5 sticks to the roll start 2 and the other adhesive zone 7 to the adjacent section 8 of the outer paper layer.

Durch das Abschneiden der Kante 3 unter einem anderen Winkel als dem rechten Winkel und das damit einhergehende schräge Anbringen des Klebestreifens 4 wird erreicht, daß die Perforierung 9 des Klebestreifens 4 beim Rollenkleben während des Rollenwechsels von einer Seite her zuverlässig aufgerissen wird.By cutting off the edge 3 at an angle other than the right angle and the associated oblique attachment of the adhesive strip 4 it is achieved that the perforation 9 of the adhesive strip 4 is reliably torn open from one side during roll gluing during the roll change.

Abschließend wird die Außenoberfläche des Rollenanfangs 2 mit einem Klebemittel versehen, um eine Anklebefläche zu bilden, die ein sicheres Aufreißen der Perforierung gewährleistet. Und zwar wird die Außenoberfläche vorzugsweise vom Klebestreifen 4 aus mit zur Abwickelrichtung parallel verlaufenden beidseitig klebenden Streifen 10 oder mit flächig aufgetragenem Klebstoff versehen. Auf diese Anklebefläche wird dann beim Rollenkleben der Endabschnitt der zu ersetzenden Restrolle gedrückt.Finally, the outer surface of the beginning of the roll 2 is provided with an adhesive in order to form an adhesive surface which ensures that the perforation is torn open. Specifically, the outer surface is preferably provided from the adhesive strip 4 with strips 10 which are adhesive on both sides and run parallel to the unwinding direction, or with adhesive applied to the surface. The end section of the remaining roll to be replaced is then pressed onto this adhesive surface during roll gluing.

Wenn es beim speziellen Ausführungsbeispiel günstiger ist, können die Streifen 10 auch in jeder anderen, sich als vorteilhaft erweisenden Richtung als der zur Abwickelrichtung parallelen aufgetragen werden. Im Falle des flächigen Auftragens von Klebstoff kann die Zone 5 des Klebestreifens 4 einseitig selbstklebend ausgebildet sein, wobei dann der Klebstoff auch auf die Zone 5 aufzutragen ist.If it is more favorable in the specific embodiment, the strips 10 can also be applied in any other direction which has proven to be advantageous than that which is parallel to the unwinding direction. In the case of the flat application of adhesive, the zone 5 of the adhesive strip 4 can be self-adhesive on one side, the adhesive then also having to be applied to the zone 5.

In einer weiteren vorteilhaften Ausführungsform der Erfindung werden die Streifen 10 bei gleichzeitiger Verwendung eines Klebestreifens 4 mit einseitig klebender Zone 5 von einer auf der Zone 5 unmittelbar neben der Perforierung verlaufenden Linie aus aufgebracht.In a further advantageous embodiment of the invention, the strips 10 are applied with a simultaneous use of an adhesive strip 4 with a zone 5 which is adhesive on one side, from a line running on the zone 5 directly next to the perforation.

Alle Schritte der vorstehend beschriebenen Rollenvorbereitung können entweder von Hand, dabei teilweise auch unter Verwendung von Handgeräten, wie etwa eines Klebestreifenspenders, oder aber auch vollautomatisch ausgeführt werden. Im letzteren Fall ist der Rollenwechsler oder ein oder mehrere vorgeschaltete Stationen für die einzelnen Schritte in geeigneter Weise mit an sich bekannten Vorrichtungen, wie etwa einem maschinell betätigbaren Messer, ausgestattet.All steps of the roll preparation described above can either be carried out by hand, in some cases also using hand-held devices, such as an adhesive tape dispenser, or else fully automatically. In the latter case, the reel changer or one or more upstream stations for the individual steps are suitably equipped with devices known per se, such as a machine-operated knife.
