Abstract

The gluing device has a number of holes (12) in the first layer (3) of the roll near the beginning of the paper strip., and a double-sided glue strip on the outside of the first layer of the roll, at least partly overlapping the holes. The glue forced through the holes attaches the beginning (2) of the paper strip to the second layer (8). The holes are in a part of the first layer near the beginning of the roll. There is a clearance between the edges of the holes and the beginning of the roll. The cross section of the holes in the first layer of the paper strip may be round or of some other geometric shape.

Description

Die Erfindung betrifft eine Klebemittelanordnung zum Vorbereiten einer Vorratspapierbahnrolle für miteinander zu verbindende Papierbahnrollen entsprechend dem Oberbegriff des Anspruches 1.The invention relates to an adhesive arrangement for preparing a supply paper web roll for paper web rolls to be connected to one another in accordance with the preamble of claim 1.

Durch die EP 04 18 527 A2 ist ein Verfahren zum Vorbereiten einer Rolle bahnförmigen Bedruckstoffes für automatische Rollenwechsler bekannt, mit welchem ein Klebestreifen zum Befestigen des Rollenanfanges der Bedruckstoffbahn auf der äußeren Bedruckstoffbahnlage verwendet wird, der über seine gesamte Länge in drei Zonen unterteilt ist. Dabei sind die äußeren Zonen mit Klebstoff versehen und die mittlere Zone ist perforiert und klebstofffrei ausgebildet.EP 04 18 527 A2 discloses a method for preparing a roll of web-shaped printing material for automatic roll changers, with which an adhesive strip is used to fasten the beginning of the roll of the printing material web on the outer printing material web layer, which is divided into three zones over its entire length. The outer zones are provided with adhesive and the middle zone is perforated and adhesive-free.

Der bei diesem Verfahren verwendete Klebestreifen weist infolge beidseitigem Klebemittelauftrag zuzüglich zu den zu verbindenden Bedruckstoffbahnen eine hohe Belastung für die Zylinder beim Durchgang durch Rotationsdruckmaschinen auf. Dadurch kann es zu bleibenden Verformungen im Drucktuch kommen, was zum vorzeitigen Verschleiß desselben führt.
Weitere Folgeerscheinungen sind, daß beim Weiterverarbeiten der Materialbahn durch Längsschneideeinrichtungen oder Falzeinrichtungen die Messer beim Schneiden solcher vielschichtigen Verbindungselemente auf die Dauer größere Verschleißerscheinungen aufweisen.
Schließlich ist auch noch von Nachteil, daß der nach dem o. g. Verfahren bekannte, dreizonige Klebestreifen - im Querschnitt gesehen - eine unterschiedliche, d. h. asymmetrische Dicke besitzt, so daß dieser dreizonige Klebestreifen nicht symmetrisch aufrollbar ist. Dies ist sowohl nachteilig für die Lagerhaltung als auch nachteilig für eine automatisierte Zuführung für eine Klebevorbereitung der Materialbahnen. Weiterhin sind noch sogenannte Zuhalteetiketten bekannt, welche einzeln und zumeist rechtwinklig auf den Anfang der ersten Lage der Papierbahn aufgeklebt werden und diese erste Lage auf der zweiten Lage der Papierbahn festlegen. Nachteilig bei diesen Zuhalteetiketten ist jedoch, daß diese jeweils einzeln und somit zeitaufwendig auf den Anfang der Papierbahn aufgebracht werden müssen und darüberhinaus auf die Vorratspapierbahnrolle noch ein zusätzlicher Klebestreifen für das Verbinden der Vorratspapierbahnrolle mit der ablaufenden Papierbahnrolle aufgebracht werden muß.As a result of the application of adhesive on both sides, in addition to the printing material webs to be connected, the adhesive strip used in this process has a high load on the cylinders when they pass through rotary printing machines. This can lead to permanent deformations in the printing blanket, which leads to premature wear.
Further sequelae are that when further processing the material web by slitting or folding devices the Knives when cutting such multi-layered connecting elements in the long run have greater signs of wear.
Finally, it is also disadvantageous that the three-zone adhesive strip known by the above-mentioned method has a different, ie asymmetrical, thickness, so that this three-zone adhesive strip cannot be rolled up symmetrically. This is both disadvantageous for warehousing and disadvantageous for an automated feed for preparing the adhesive for the material webs. Furthermore, so-called tumbler labels are also known, which are attached individually and mostly at right angles to the beginning of the first layer of the paper web and define this first layer on the second layer of the paper web. A disadvantage of these tumbler labels, however, is that they have to be applied individually and thus time-consuming to the beginning of the paper web and, in addition, an additional adhesive strip for connecting the stock paper web roll to the outgoing paper web roll must be applied to the stock paper roll.

Der Erfindung liegt die Aufgabe zugrunde, eine etikettenfreie Klebemittelanordnung zum Vorbereiten einer neuen Vorratspapierbahnrolle für das Verbinden mit einer zu Ende gehenden Papierbahnrolle in einem Rollenwechsler zu schaffen, welche bei einer guten Maschinengängigkeit einfach sowohl im Rollenwechsler vor Ort als auch in einer automatischen Station zum Herstellen von Klebespitzen hergestellt werden kann.The invention has for its object to provide a label-free adhesive arrangement for preparing a new supply paper web reel for connection to an outgoing paper web reel in a reel changer, which with good machine movement is easy both in the reel changer can be produced on site as well as in an automatic station for producing adhesive tips.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of claim 1.

Durch die Erfindung werden insbesondere folgende Vorteile erzielt:
Infolge des Aufbringens eines parallel zum Papierbahnanfang verlaufenden bekannten, einfachen und unperforierten Klebemittelstreifens sowie das durch die Öffnungen der obersten Lage der Papierbahn auf die zweite Lage der Papierbahn tretende Klebemittel ist mit wenig Aufwand und ohne sogenannte Zuhalteetiketten eine Klebemittelanordnung zur Vorbereitung für das Verbinden der ersten Lage einer neuen Vorratspapierbahnrolle mit der Papierbahn einer abgelaufenen Papierbahnrolle geschaffen worden. Dieser Klebemittelstreifen garantiert hinsichtlich seiner Dicke eine beschädigungsfreie Maschinengängigkeit sowie ein komplikationsloses Verbinden zweier Papierbahnen mit nachfolgendem Trennen der auf der zweiten Papierbahnlage aufgeklebten ersten Papierbahnlage von der ersten Papierbahnlage. Die Klebekraft des Anfanges der ersten Lage der Papierbahn auf der zweiten Lage der Papierbahn ist so bemessen, daß beim Drehen der Papierbahnrolle in der Anlaufphase allein die Luftwiderstandskräfte ein selbsttätiges Öffnen des Anfanges der Vorratspapierbahnrolle nicht bewirken können. Der verwendete Klebemittelstreifen ist auf Grund seines gleichmäßigen Querschnitts gut aufrollbar.The following advantages are achieved in particular by the invention:
As a result of the application of a known, simple and imperforate strip of adhesive running parallel to the beginning of the paper web and the adhesive passing through the openings in the top layer of the paper web onto the second layer of the paper web, an adhesive arrangement can be prepared with little effort and without so-called locking labels in preparation for the connection of the first layer a new stock paper web roll was created with the paper web of an expired paper web roll. With regard to its thickness, this strip of adhesive guarantees damage-free machine movement and uncomplicated connection of two paper webs with subsequent separation of the first paper web layer glued onto the second paper web layer from the first paper web layer. The adhesive force of the beginning of the first layer of the paper web on the second layer of the paper web is such that when the paper web roll is turned in the start-up phase, the air resistance forces alone cannot cause the beginning of the stock paper web roll to open automatically. The adhesive strip used is easy to roll up due to its uniform cross-section.

Eine Papierbahnrolle als Vorratspapierbahnrolle zum Verbinden an eine nahezu abgelaufene Papierbahnrolle weist in der Nähe ihres Papierbahnanfanges 2 der äußersten oder ersten Lage 3 der Papierbahn eine Vielzahl von Öffnungen oder Löcher 4 auf, die parallel zum Papierbahnanfang 2, z. B. parallel zur Achse der Vorratspapierbahnrolle verlaufen, jedoch den Papierbahnanfang 2 nicht berühren (Fig. 1). Diese Löcher 4 sind im Querschnitt vorzugsweise kreisrund ausgebildet; sie können jedoch auch einen ovalen, rechteckigen, dreieckigen oder einen Querschnitt einer beliebigen geometrischen Form aufweisen. Über diese in der ersten Lage 3 der Papierbahn eingebrachten Löcher 4 wird ein doppelseitig klebender Klebemittelstreifen 6 aufgebracht, welcher mit seiner Seitenlinie 7 parallel zum Papierbahnanfang 2 der ersten Lage 3 der Papierbahn verläuft und dessen Klebemittel durch die in der ersten Lage 3 der Papierbahn befindlichen Löcher 4 tritt und somit den Anfang der ersten Lage 3 der Papierbahn auf einer zweiten Lage 8 der Papierbahn festlegt. Die Löcher 4 können dabei sowohl vollständig oder auch nur teilweise mit dem Klebemittelstreifen 6 abgedeckt sein. Somit ist die Wirksamkeit des Befestigens der erste Lage 3 der Papierbahn auf der zweiten Lage 8 der Papierbahn neben der Klebekraft des Klebemittels vom Durchmessers d der Löcher 4, vom Abstand a der Löcher 4 voneinander sowie vom Grad der Überdeckung der Löcher 4 durch den Klebemittelstreifen 6 abhängig und somit einstellbar. Der Durchmesser jedes Loches 4 kann drei bis fünf Millimeter betragen. Der Anstand a der Löcher 4 in achsparalleler Richtung kann zwischen 50 und 100 Millimetern liegen. Dabei können auch zwei Lochreihen parallel zueinander in achsparalleler Richtung verlaufen. Der Klebemittelstreifen 6 weist eine Breite b auf, welche zwischen 12 und 50 Millimetern liegen kann. Die Löcher 4 befinden sich dabei in einem papierbahnanfangsnahem Bereich des Anfanges Gebiet der ersten Lage 3 der Papierbahn, so daß sich zwischen der papierbahnanfangsnächsten Stelle der Löcher 4 und dem Papierbahnanfang 2 der ersten Lage 3 ein kleiner Abstand e befindet. Dieser Abstand e beträgt mindestens das 0,2-fache eines Durchmessers d eines Loches 4.A paper web roll as a supply paper web roll for connection to an almost expired paper web roll has in the vicinity of its paper web start 2 the outermost or first layer 3 of the paper web a plurality of openings or holes 4 which are parallel to the paper web start 2, z. B. run parallel to the axis of the stock paper roll, but the Do not touch the beginning of the paper web 2 (Fig. 1). These holes 4 are preferably circular in cross section; however, they can also have an oval, rectangular, triangular or a cross-section of any geometric shape. About these holes 4 made in the first layer 3 of the paper web, a double-sided adhesive strip 6 is applied, which extends with its side line 7 parallel to the beginning of the paper web 2 of the first layer 3 of the paper web and its adhesive through the holes in the first layer 3 of the paper web 4 occurs and thus defines the beginning of the first layer 3 of the paper web on a second layer 8 of the paper web. The holes 4 can be completely or only partially covered with the adhesive strip 6. Thus, the effectiveness of attaching the first layer 3 of the paper web to the second layer 8 of the paper web is, in addition to the adhesive force of the adhesive, of the diameter d of the holes 4, the distance a of the holes 4 from one another and the degree of coverage of the holes 4 by the adhesive strip 6 dependent and thus adjustable. The diameter of each hole 4 can be three to five millimeters. The distance a between the holes 4 in the axis-parallel direction can be between 50 and 100 millimeters. Two rows of holes can also run parallel to one another in the direction parallel to the axis. The adhesive strip 6 has a width b, which can be between 12 and 50 millimeters. The holes 4 are in one Area of the first layer 3 of the paper web near the beginning of the paper web, so that there is a small distance e between the point of the holes 4 closest to the beginning of the paper web and the beginning of the paper web 2 of the first layer 3. This distance e is at least 0.2 times a diameter d of a hole 4.

Es ist auch möglich, den Papierbahnanfang 2 der ersten Lage 3 der Papierbahn in ihrem Verlauf abweichend von einer Achsparallelen auszubilden, z. B. schräg, V-förmig, W-förmig oder Doppel-W-förmig verlaufend. Dabei verläuft die Seitenlinie 7 des Klebemittelstreifens 6 entweder deckungsgleich zum Papierbahnanfang 2 der ersten Lage 3 der Papierbahn, oder der Papierbahnanfang 2 sowie die Seitenlinie 7 verlaufen in einem Abstand parallel zueinander. In letzterem Falle befindet sich jedoch die Seitenlinie 7 des Klebemittelstreifens 6 auf dem Anfang 9 der ersten Lage 3 der Papierbahn und nicht auf der zweiten Lage 8 der Papierbahn.It is also possible to form the beginning of the paper web 2 of the first layer 3 of the paper web in its course deviating from an axis parallel, z. B. oblique, V-shaped, W-shaped or double W-shaped. The side line 7 of the adhesive strip 6 either runs congruent to the beginning of the paper web 2 of the first layer 3 of the paper web, or the beginning of the paper web 2 and the side line 7 run parallel to one another at a distance. In the latter case, however, the side line 7 of the adhesive strip 6 is on the beginning 9 of the first layer 3 of the paper web and not on the second layer 8 of the paper web.

Das Verbinden der Papierbahn einer Vorratspapierbahnrolle an eine von einer zu Ende gehenden Papierbahnrolle erfolgt in bekannter Weise, wie z. B. in der DE 42 10 329 A1 dargestellt. Dabei wird die zu Ende gehende Papierbahn mittels einer Andrückrolle an den Anfang 9 der ersten Lage 3 der Vorratspapierbahnrolle gedrückt, so daß die zu Ende gehende Papierbahn die der ersten Lage 3 der Papierbahn abgewandte Oberfläche 11 des Klebemittelstreifens 6 berührt, wodurch der Anfang 9 der ersten Lage 3 der Papierbahn angeklebt wird. Nach diesem Verbinden beider Papierbahnen lösen sich die kreisförmigen Klebestellen von der zweiten Lage 8 der Papierbahn ab, so daß der Verbindungsvorgang beider Papierbahnen hiermit beendet ist. Als Klebeband kann handelsübliches Klebeband verwendet werden. Nach der genannten Andrückrolle und noch innerhalb des Rollenwechslers kann zweckmäßigerweise eine an die Papierbahn anstellbare Walze oder eine im Papierlauf vorhandene Leitwalze angeordnet sein, welche von der Außenseite der von der Papierbahnrolle ablaufenden Papierbahn umschlungen ist, so daß die der Papierbahn anhaftenden lochförmig angeordneten Klebemittelrückstände inaktiviert werden, z. B. mittels Silikon, Puder oder dgl. bekannten Mitteln.The connection of the paper web of a supply paper web roll to one of a paper web roll coming to an end is carried out in a known manner, such as, for. B. in DE 42 10 329 A1. The end of the paper web is pressed by means of a pressure roller onto the start 9 of the first layer 3 of the supply paper roll, so that the end of the paper web is that of the first layer 3 of the paper web touches away surface 11 of the adhesive strip 6, whereby the beginning 9 of the first layer 3 of the paper web is glued. After this connection of the two paper webs, the circular adhesive sites separate from the second layer 8 of the paper web, so that the connection process of both paper webs is hereby ended. Commercially available adhesive tape can be used as the adhesive tape. After the pressure roller mentioned and still inside the reel changer, a roll that can be placed on the paper web or a guide roller that is present in the paper path can be expediently wrapped around the outside of the paper web running off the paper web roll, so that the hole-shaped adhesive residues adhering to the paper web are deactivated , e.g. B. by means of silicone, powder or the like. Known means.

Bei einem weiteren Ausführungsbeispiel weist eine Vorratspapierbahnrolle an ihrem Papierbahnanfang 2 der äußersten oder ersten Lage 3 der Papierbahn eine Vielzahl von Ausnehmungen oder Löcher 12 auf, welche parallel zum Papierbahnanfang 2 und z. B. parallel zur Achse der Papierbahnrolle (Fig. 4) verlaufen und den Papierbahnanfang 2 der ersten Lage 3 der Papierbahn berühren. Diese Löcher 12 sind im Querschnitt vorzugsweise dreieckig ausgebildet, so daß deren Grundlinien 10 deckungsgleich mit dem Papierbahnanfang 2 der ersten Lage 3 der Papierbahn verlaufen und deren Höhen h sich rechtwinklig zum Papierbahnanfang 2 der ersten Lage 3 der Papierbahn erstrecken. Die Grundlinie 10 jeder dreieckigen Ausnehmung bzw. jedes dreieckigen Loches 12 an dem Papierbahnanfang 2 der ersten Lage 3 der Papierbahn wird jeweils durch die Punkte 13; 14 begrenzt und die Höhe h wird einerseits von der Grundlinie 10 und andererseits von einem Schnittpunkt 16 der beiden von den Punkten 13; 14 ausgehenden Geraden 17; 18 begrenzt. Diese Löcher 12 können jedoch auch einen Teil einer runden, ovalen oder anderen beliebigen geometrischen Form aufweisen. Die Löcher 12 können ebenfalls einen kreisabschnittsförmigen Querschnitt aufweisen, deren Sekante auf dem Papierbahnanfang 2 verläuft und der Grundlinie 10 entspricht. Wichtig ist, daß diese geometrische Form zum Papierbahnanfang 2 der ersten Lage 3 der Papierbahn Verbindung hat, d. h. geöffnet ist und von dem Papierbahnanfang 2 ausgehend, sich entgegen der Drehrichtung der Vorratspapierbahnrolle, d. h. in Richtung des Schnittpunktes 16 der beiden Geraden 17, 18 verjüngt. Über diese in einem streifenförmigen Bereich 19 des Papierbahnanfanges 2 der ersten Lage 3 der Papierbahn befindlichen Löcher 12 ist ein doppelseitig klebender Klebemittelstreifen 6 aufgebracht, so daß auf der zweiten Lage 8 der Papierbahn jeweils eine dreieckförmige Klebfläche 21 entsteht, welche sowohl durch die Seitenlinie 7 des Klebemittelstreifens 6, welche die beiden Geraden 17; 18 in den Punkten 22; 23 schneidet, als auch durch den Schnittpunkt 16 der beiden Geraden 17; 18 begrenzt wird. Der Papierbahnanfang 2 der ersten Lage 3 der Papierbahn kann abweichend von einer Achsparallelen (wie in Fig. 4 dargestellt) ausgebildet sein, z. B. schräg, V-förmig, W-förmig oder Doppel-W-förmig. Dabei verläuft ebenfalls, wie im ersten Ausführungsbeispiel angegeben, die Seitenlinie 7 des Klebemittelstreifens 6 entweder deckungsgleich zum Papierbahnanfang 2 der ersten Lage 3 der Papierbahn oder der Papierbahnanfang 2 sowie die Seitenlinie 7 verlaufen parallel zueinander in einem streifenförmigen Abstand f. Die Breite des streifenförmigen Abstandes f kann z. B. gleich der Höhe h des Loches 12 oder einem Teils dieser Höhe h betragen, so daß die Löcher 12 vom Klebemittelstreifen 6 ganz oder teilweise überdeckt werden und somit analog dem ersten Ausführungsbeispiel die Klebekraft der Klebestellen einstellbar ist. In letzterem Falle befindet sich auch hier die Seitenlinie 7 des Klebemittelstreifens 6 auf dem Anfang der ersten Lage 3 der Papierbahn und nicht auf der zweiten Lage 8 der Papierbahn. Ein Abstand a der Löcher 12 sowie eine Breite b des Klebemittelstreifens sind jeweils ebenso bemessen, wie im ersten Ausführungsbeispiel dargelegt.In a further embodiment, a supply paper roll on its paper web start 2 of the outermost or first layer 3 of the paper web has a plurality of recesses or holes 12 which are parallel to the paper web start 2 and z. B. run parallel to the axis of the paper web roll (FIG. 4) and touch the beginning of the paper web 2 of the first layer 3 of the paper web. These holes 12 are preferably triangular in cross section, so that their base lines 10 are congruent with the beginning of the paper web 2 of the first layer 3 of the paper web run and their heights h extend at right angles to the beginning of the paper web 2 of the first layer 3 of the paper web. The base line 10 of each triangular recess or triangular hole 12 at the beginning of the paper web 2 of the first layer 3 of the paper web is in each case indicated by the points 13; 14 and the height h is determined on the one hand by the base line 10 and on the other hand by an intersection 16 of the two from the points 13; 14 outgoing straight lines 17; 18 limited. However, these holes 12 can also have a part of a round, oval or any other geometrical shape. The holes 12 may also have a circular cross-section, the secant of which runs on the beginning of the paper web 2 and corresponds to the base line 10. It is important that this geometric shape has a connection to the beginning of the paper web 2 of the first layer 3 of the paper web, ie it is open and starting from the beginning of the paper web 2, tapers against the direction of rotation of the supply paper web roll, ie in the direction of the intersection 16 of the two straight lines 17, 18. A double-sided adhesive strip 6 is applied over these holes 12 located in a strip-shaped area 19 of the beginning of the paper web 2 of the first layer 3 of the paper web, so that a triangular adhesive surface 21 is formed on the second layer 8 of the paper web, which is formed both by the side line 7 of the Adhesive strip 6, which the two straight lines 17; 18 in points 22; 23 intersects, as well as through the intersection 16 of the two Straight line 17; 18 is limited. The beginning of the paper web 2 of the first layer 3 of the paper web can deviate from an axis parallel (as shown in Fig. 4), z. B. oblique, V-shaped, W-shaped or double W-shaped. As indicated in the first exemplary embodiment, the side line 7 of the adhesive strip 6 likewise runs either congruent with the beginning of the paper web 2 of the first layer 3 of the paper web or the beginning of the paper web 2 and the side line 7 run parallel to one another at a strip-shaped distance f. The width of the strip-shaped distance f can, for. B. equal to the height h of the hole 12 or a portion of this height h, so that the holes 12 are completely or partially covered by the adhesive strip 6 and thus analogous to the first embodiment, the adhesive force of the adhesive points is adjustable. In the latter case, the side line 7 of the adhesive strip 6 is also on the beginning of the first layer 3 of the paper web and not on the second layer 8 of the paper web. A distance a between the holes 12 and a width b of the adhesive strip are dimensioned in each case as set out in the first exemplary embodiment.
