An insert formed by a further paper band can be stuck between the at least two layers of the paper strip .

Description

Die gegenständliche Erfindung betrifft eine Einrichtung zum Unterteilen einer sich bewegenden Papierbahn, welche auf eine Trommel aufgewickelt wird, um hierdurch deren Aufwicklung auf eine leere Trommel zu ermöglichen, bestehend aus einem aus Papier gefertigten Reißband.The present invention relates to a device for dividing a moving paper web, which is wound on a drum, thereby enabling it to be wound on an empty drum, consisting of a tear tape made of paper.

Bei der Aufwicklung einer in einer Anlage zur Herstellung von Papier gefertigten Papierbahn auf Spulen besteht das Erfordernis dann, sobald eine Spule einen vorgegebenen Wickeldurchmesser erreicht hat, die sich mit einer Geschwindigkeit von etwa 25 m/Sekunde bewegende Papierbahn zu unterteilen, um die Aufwicklung der folgenden Papierbahn auf einer leeren Spule fortsetzen zu können. Hierfür wird ein Reißband verwendet, welches sich auf der leeren Spule spiralig aufwickelt, wobei gleichzeitig die Papierbahn längs einer spiralen Linie unterteilt wird. Um das Reißband zugleich mit den durch den Trennvorgang beschädigten Teilen der Papierbahn einer Wiederverwertung zuführen zu können, ist es bekannt, dieses aus Papier zu fertigen.When winding a paper web manufactured in a plant for the production of paper on spools, the requirement exists, as soon as a spool has reached a predetermined winding diameter, to divide the paper web moving at a speed of about 25 m / second in order to wind the following ones To be able to continue the paper web on an empty spool. A tear tape is used for this, which spirally winds on the empty spool, at the same time dividing the paper web along a spiral line. In order to be able to recycle the tear tape at the same time as the parts of the paper web damaged by the separating process, it is known to manufacture it from paper.

Ein derartiges Reißband, welches eine große Zugfestigkeit und eine hohe Steifigkeit aufweisen muß, wird bislang aus einer Vielzahl von nebeneinander liegenden und miteinander verklebten Schnüren aus Papier hergestellt. Zur Erzielung des Klebevorganges werden die Papierschnüre über ihre gesamte Oberfläche mit einem wasserlöslichen Klebstoff benetzt. Da sie in der Folge aneinander liegend miteinander verpreßt werden, verkleben sie an den Berührungsflächen aneinander. Nach dem Trocknungsprozeß des Klebstoffes wird das derart hergestellte Reißband zu einer Rolle aufgewickelt.Such a tear tape, which must have great tensile strength and high rigidity, has hitherto been produced from a large number of paper cords lying side by side and glued to one another. To achieve the gluing process, the paper cords are wetted over their entire surface with a water-soluble adhesive. Since they are subsequently pressed together, they stick together on the contact surfaces. After the adhesive has dried, the tear tape thus produced is wound up into a roll.

Einem bekannten derartigem Reißband haften jedoch mehrere Nachteile an:
Da die Schnüre bei ihrer Herstellung über den gesamten Umfang mit Klebstoff benetzt werden, kann das zu einer Spule gewickelte Reißband unter Einfluß von Feuchtigkeit verkleben. Weiters können sich unter Einfluß von Feuchtigkeit die miteinander verklebten Papierschnüre voneinander lösen, wodurch die Festigkeit des Reißbandes vermindert wird und zudem bei dessen Verwendung Störungen bedingt werden können. Ein weiterer Nachteil dieses bekannten Reißbandes besteht darin, daß die einzelnen Papierschnüre, aus welchen es gefertigt ist, einen Mindestdurchmesser aufweisen müssen, wodurch dieses Reißband eine Mindestdicke aufweist, welche bei der Verwendung eines solchen Bandes zum Unterteilen von Papierbahnen mit relativ geringem Papiergewicht deshalb nachteilige Effekte bedingen kann, da die Papierbahn beschädigt wird. Weiters besteht das Erfordernis, ein derartiges Reißband mit exakten Toleranzen zu fertigen, um hierdurch Störungen bei dessen Bewegung durch einen Förderkanal ausschließen zu können. Diesem Erfordernis kann jedoch bei einem aus mehreren Schnüren hergestellten Reißband deshalb nur schwer entsprochen werden, da die Schnüre nicht mit exakten Größen gefertigt werden können.A known tear tape of this type has several disadvantages:
Since the cords are wetted over their entire circumference with adhesive during manufacture, the tear tape wound into a spool can stick together under the influence of moisture. Furthermore, under the influence of moisture, the paper cords glued together can come apart, which increases the strength of the tear tape is reduced and, moreover, malfunctions can be caused when it is used. Another disadvantage of this known tear tape is that the individual paper cords from which it is made must have a minimum diameter, which means that this tear tape has a minimum thickness, which therefore has disadvantageous effects when such a tape is used to divide paper webs with a relatively low paper weight can cause, since the paper web is damaged. Furthermore, there is a need to manufacture such a tear tape with exact tolerances in order to be able to rule out disruptions in its movement through a conveying channel. However, this requirement can only be met with difficulty with a tear tape made from several cords, since the cords cannot be manufactured with exact sizes.

Zudem werden bei einem Auftrennen des Reißbandes die einzelnen Schnüre an unterschiedlichen Stellen des Längsverlaufes des Reißbandes abgetrennt, wodurch in der Folge gleichfalls Funktionsstörungen bedingt werden können. Weiters sind aus gedrehten Schnüren gefertigte Reißbänder im Recyclingprozeß nur schwer auflösbar.In addition, when the tear tape is cut, the individual cords are cut off at different points along the longitudinal course of the tear tape, which can also result in malfunctions. Furthermore, tear tapes made from twisted cords are difficult to dissolve in the recycling process.

Schließlich haften flächige Schichten von Klebstoff, welche auf ein derartiges Reißband aufgebracht werden und welche dazu dienen, das Reißband an der leeren Spule zu befestigen, um in der Folge den Trennvorgang der Papierbahn einleiten zu können, auf einem durch Papierschnüre gebildeten Reißband nur längs der außen liegenden Mantellinien der Papierschnüre, wodurch diese Klebstoffschichten abgelöst werden können.Finally, flat layers of adhesive, which are applied to such a tear tape and which serve to fasten the tear tape to the empty spool in order to subsequently initiate the separation process of the paper web, only adhere to a tear tape formed by paper cords along the outside horizontal lines of the paper cords, whereby these adhesive layers can be detached.

Der gegenständlichen Erfindung liegt demnach die Aufgabe zugrunde, ein aus Papier gefertigtes Reißband zu schaffen, durch welches die dem bekannten, aus einzelnen Schnüren gefertigten, Reißband anhaftenden Nachteile vermieden werden. Dies wird erfindungsgemäß dadurch erzielt, daß das Reißband durch mindestens einen mehrfach gefalteten Papierstreifen gebildet ist, wobei die aneinander liegenden Lagen des Papierstreifens miteinander zumindest partiell verklebt sind.The object of the present invention is therefore to provide a tear tape made of paper, by means of which the disadvantages inherent in the known tear tape made from individual cords are avoided. This is achieved according to the invention in that the tear tape is formed by at least one multiply folded paper strip is, the adjacent layers of the paper strip are at least partially glued to each other.

Dabei können die beiden seitlichen Bereiche des Papierstreifens mehrfach umgebogen sein. Vorzugsweise sind die beiden seitlichen Bereiche des Papierstreifens auf eine Seite hin umgebogen. Alternativ dazu sind die beiden seitlichen Bereiche des Papierstreifens auf unterschiedliche Seiten hin umgebogen. Dabei können sich die beiden Seitenkanten des Papierstreifens etwa in der Mitte des Reißbandes befinden.The two lateral areas of the paper strip can be bent several times. The two lateral regions of the paper strip are preferably bent over on one side. Alternatively, the two lateral areas of the paper strip are bent over on different sides. The two side edges of the paper strip can be located approximately in the middle of the tear tape.

Nach einer anderen bevorzugten Ausführungsform sind die beiden seitlichen Bereiche des Papierstreifens auf eine Seite hin umgebogen, wobei sie sich überlappen und sich vorzugsweise die beiden Seitenränder des Papierstreifens im Bereich der beiden Seitenkanten des Reißbandes befinden. Weiters kann zwischen den mindestens zwei Lagen des Papierstreifens eine durch mindestens ein weiteres Papierband gebildete Einlage angeordnet sein, welche mit dem Papierstreifen gleichfalls verklebt ist. Insbesondere kann dabei die Einlage durch einen mehrlagigen, allenfalls ebenfalls gefalteten Papierstreifen gebildet sein. Zudem kann die Einlage durch einen auf beiden Seiten mit Klebstoff versehenen Papierstreifen oder durch einen Streifen eines Klebstoffes gebildet sein.According to another preferred embodiment, the two lateral areas of the paper strip are bent over on one side, where they overlap and the two side edges of the paper strip are preferably located in the area of the two side edges of the tear tape. Furthermore, an insert formed by at least one further paper tape can be arranged between the at least two layers of the paper strip and is also glued to the paper strip. In particular, the insert can be formed by a multi-layer, possibly also folded paper strip. In addition, the insert can be formed by a paper strip provided with adhesive on both sides or by a strip of adhesive.

Nach einem weiteren bevorzugten Merkmal ist der mindestens eine Papierstreifen aus Papiermaterial mit einer Langfaserorientierung gefertigt. Um dieses Reißband in Querrichtung flexibel zu gestalten, kann es zudem mit in Längsrichtung verlaufenden Rillen od. dgl. versehen bzw. in seiner Querrichtung gewellt ausgebildet sein.According to a further preferred feature, the at least one paper strip is made of paper material with a long fiber orientation. In order to make this tear tape flexible in the transverse direction, it can also be provided with grooves or the like running in the longitudinal direction or be corrugated in its transverse direction.

Durch ein derartiges Reißband werden sämtliche dem bekannten Reißband anhaftenden Nachteile vermieden:Such a tear tape avoids all the disadvantages inherent in the known tear tape:

Durch Auswahl der Papierstärken und der Anzahl der Papierlagen kann es mit jeglicher Zugfestigkeit und Steifigkeit hergestellt werden, wodurch eine genaue Anpassung an die Dicke bzw. Qualität des Papieres derjenigen Papierbahn, welche unterteilt werden soll, erzielbar ist. Da sich an der Außenseite des Reißbandes kein Klebstoff befindet, können keine Verklebungen des aufgespulten Reißbandes bedingt werden. Da sich vielmehr der Klebstoff nur innerhalb des Reißbandes befindet, wird zudem verhindert, daß die Verklebung durch Feuchtigkeit gelöst wird, wodurch die Zugfestigkeit des Reißbandes vermindert wird.By selecting the paper thicknesses and the number of paper layers, it can be manufactured with any tensile strength and rigidity, which enables precise adjustment to the thickness or Quality of the paper of the paper web that is to be divided can be achieved. Since there is no adhesive on the outside of the tear tape, no sticking of the unwound tear tape can be caused. Rather, since the adhesive is only inside the tear tape, the bond is prevented from being loosened by moisture, thereby reducing the tensile strength of the tear tape.

Weiters ist ein aus mehrlagigen, miteinander mittels eines wasserlöslichen Klebstoffes verklebten Papierbändern gefertigtes Reißband im Recyclingprozeß leichter auflösbar und ist es daher besser wiederverwertbar. Zudem wird ein derartiges Reißband bei seiner Abtrennung längs einer angenähert geraden Kante abgetrennt, wodurch keine Papierreste bedingt werden, welche im Förderkanal Funktionsstörungen bedingen können. Da weiters ein derartiges Reißband zwar geradlinig verlaufende aber nicht scharfe Längskanten aufweist, wird durch dieses ein optimaler Verlauf bei der Unterteilung der Papierbahn gewährleistet. Da zudem ein derartiges Reißband eine angenähert ebene Oberfläche aufweist, haften auf diesem flächige Schichten von Klebstoff so gut, daß sie nicht abgelöst werden können. Schließlich kann ein derartiges Reißband in unbeschränkten Längen hergestellt werden.Furthermore, a tear tape made from multilayer paper tapes glued to one another by means of a water-soluble adhesive is easier to dissolve in the recycling process and is therefore easier to recycle. In addition, such a tear tape is cut off along an approximately straight edge, as a result of which no paper residues are caused which can cause malfunctions in the conveying channel. Furthermore, since such a tear tape has straight but not sharp longitudinal edges, this ensures an optimal course when dividing the paper web. Since such a tear tape also has an approximately flat surface, flat layers of adhesive adhere to it so well that they cannot be detached. Finally, such a tear tape can be made in unlimited lengths.

Der Gegenstand der Erfindung ist nachstehend anhand mehrerer in der Zeichnung dargestellter Ausführungsbeispiele erläutert:
Die Fig. 1 bis 9 zeigen unterschiedliche Ausführungsformen eines erfindungsgemäßen Reißbandes, jeweils in axonometrischer Darstellung.The object of the invention is explained below with reference to several exemplary embodiments shown in the drawing:
1 to 9 show different embodiments of a tear tape according to the invention, each in an axonometric representation.

Ein erfindungsgemäßes Reißband ist aus einem Papierstreifen gebildet, welcher mehrfach gefaltet ist, wobei die aneinander liegenden Lagen des Papierstreifens mittels eines wasserlöslichen Klebstoffes miteinander verklebt sind. Dabei befindet sich der Klebstoff innerhalb des Reißbandes und sind dessen Außenseiten von Klebstoff freigehalten.A tear tape according to the invention is formed from a paper strip which is folded several times, the layers of the paper strip lying against one another being glued to one another by means of a water-soluble adhesive. The adhesive is located inside the tear tape and the outside of it is kept free of adhesive.

Nach dem Ausführungsbeispiel der Fig. 1 ist das Reißband aus einem Papierstreifen 1 gebildet, dessen seitliche Bereiche 11 und 12 über dem mittleren Bereich 10 auf eine Seite hin so umgebogen sind, daß deren Längskanten dicht aneinander liegen. Die aneinander liegenden Lagen sind mittels einer Schichte 13 eines Klebstoffes miteinander verklebt. Dieses Reißband, welches zweilagig ist, weist somit zwei durch Falze gebildete Längsränder 14 und 15 auf, durch welche der Trennvorgang der Papierbahn eingeleitet wird.According to the exemplary embodiment in FIG. 1, the tear tape is formed from a paper strip 1, the lateral regions 11 and 12 of which are bent over on one side over the central region 10 in such a way that their longitudinal edges lie close together. The layers lying one against the other are glued to one another by means of a layer 13 of an adhesive. This tear tape, which is two-ply, thus has two longitudinal edges 14 and 15 formed by folds, through which the separation process of the paper web is initiated.

In Fig. 2 ist ein erfindungsgemäßes Reißband dargestellt, welches aus einem Papierstreifen 2 gebildet ist, dessen seitliche Bereiche 21 und 22 über dem mittleren Bereich 20 übereinander gefaltet und mittels Klebstoffschichten 23 miteinander verbunden sind, wodurch ein dreilagiges Reißband gebildet ist, dessen beide Seitenränder 24 und 25 die Trennkanten bilden. Dadurch, daß dieses Reißband dreilagig ausgebildet ist, weist es gegenüber dem Reißband gemäß Fig. 1 eine erhöhte Zugfestigkeit auf.2 shows a tear tape according to the invention, which is formed from a paper strip 2, the lateral regions 21 and 22 of which are folded over one another over the central region 20 and connected to one another by means of adhesive layers 23, whereby a three-layer tear tape is formed, the two side edges 24 of which and 25 form the separating edges. The fact that this tear tape is formed in three layers, it has an increased tensile strength compared to the tear tape according to FIG. 1.

Das in Fig. 3 dargestellt Reißband unterscheidet sich vom Reißband gemäß der Fig. 2 dadurch, daß die beiden seitlichen Bereiche 31 und 32 des Papierbandes 3 auf unterschiedliche Seiten des mittleren Bereiches 30 hin gefaltet sind. Auch hierbei sind die einzelnen Lagen des Papierbandes 3 mittels Klebstoffschichten 33 miteinander verklebt. Die beiden Seiten-kanten 34 und 35 bilden die Trennkanten.The tear tape shown in FIG. 3 differs from the tear tape according to FIG. 2 in that the two lateral areas 31 and 32 of the paper tape 3 are folded onto different sides of the central area 30. Here, too, the individual layers of the paper tape 3 are glued to one another by means of adhesive layers 33. The two side edges 34 and 35 form the separating edges.

Beim Reißband gemäß Fig. 4 sind die beiden seitlichen Bereiche 41 und 42 des Papierbandes 4 über dem mittleren Bereich 40 mehrfach umgebogen, wobei die einzelnen Lagen des Reißbandes, welches vierlagig ist, mittels Klebstoffschichten 43 miteinander verbunden sind. Hierdurch wird eine noch höhere Steifigkeit und Reißfestigkeit erzielt. Die Reißkanten sind durch die Seitenränder 44 und 45 gebildet.4, the two lateral areas 41 and 42 of the paper tape 4 are bent several times over the central area 40, the individual layers of the tear tape, which has four layers, being connected to one another by means of adhesive layers 43. This results in an even higher rigidity and tear resistance. The tear edges are formed by the side edges 44 and 45.

In Fig. 5 ist ein Reißband dargestellt, welches entsprechend dem Ausführungsbeispiel der Fig. 1 aus einem Papierband 1 gefertigt ist, dessen seitliche Bereiche 11 und 12 zueinander gefaltet sind. Dabei ist zur Verstärkung des Reißbandes zwischen den hierdurch gebildeten Lagen des Papierbandes 1 ein verstärkendes Papierband 5 vorgesehen, dessen Breite der Breite des Reißbandes angenähert gleich ist und welches mit den Lagen 10, 11 und 12 des Papierbandes 1 mittels zweier Klebstoffschichten 13 verbunden ist. Die Einlage 5 kann auch durch ein Trägerband aus Papier, welches beidseitig mit einem wasserlöslichen Klebstoff beschichtet ist, oder durch ein trägerloses Klebeband gebildet sein.FIG. 5 shows a tear tape which, according to the exemplary embodiment in FIG. 1, consists of a paper tape 1 is made, the lateral regions 11 and 12 of which are folded towards one another. In order to reinforce the tear tape between the layers of paper tape 1 formed thereby, a reinforcing paper tape 5 is provided, the width of which is approximately the same as the width of the tear tape and which is connected to the layers 10, 11 and 12 of the paper tape 1 by means of two adhesive layers 13. The insert 5 can also be formed by a carrier tape made of paper, which is coated on both sides with a water-soluble adhesive, or by a carrier-free adhesive tape.

In Fig. 6 ist ein weiteres Reißband dargestellt, welches sich vom Ausführungsbeispiel gemäß Fig. 5 dadurch unterscheidet, daß das Papierband 1 drei übereinander liegende Papierbänder 51, 52, 53, welche eine verstärkende Einlage bilden, umschließt, und welche mit den Lagen des Papierbandes 1 mittels mehrerer Klebstoffschichten 13 verbunden sind.In Fig. 6 another tear tape is shown, which differs from the embodiment of FIG. 5 in that the paper tape 1 encloses three superimposed paper tapes 51, 52, 53, which form a reinforcing insert, and which with the layers of the paper tape 1 are connected by means of several adhesive layers 13.

In Fig. 7 ist ein Reißband dargestellt, welches sich vom Ausführungsbeispiel nach Fig. 1 dadurch unterscheidet, daß zwei Papierstreifen 1 und 1a miteinander verklebt sind, wobei die seitlichen Bereiche 11a und 12a des außenliegenden Papierbandes 1a über das gefalzte Papierband 1 umgebogen und mittels innen liegender Klebschichten 13 mit den anderen Lagen verklebt sind.In Fig. 7 a tear tape is shown, which differs from the embodiment of Fig. 1 in that two paper strips 1 and 1a are glued together, the lateral areas 11a and 12a of the outer paper tape 1a bent over the folded paper tape 1 and by means of the inside lying adhesive layers 13 are glued to the other layers.

In Fig. 8 ist ein Reißband dargestellt, dessen Bereiche 10, 11, 12 gemäß Fig. 1 von einem zweiten Papierband 1b so umschlossen sind, daß sich die seitlichen Bereiche 11, 12 und 11b, 12b der beiden Papierstreifen 1 und 1b an unterschiedlichen Seiten des Reißbandes befinden.In Fig. 8, a tear tape is shown, the areas 10, 11, 12 of FIG. 1 are enclosed by a second paper tape 1b so that the lateral areas 11, 12 and 11b, 12b of the two paper strips 1 and 1b on different sides of the tear tape.

Um die erforderliche Flexibilität eines derartigen Reißbandes zu erzielen, kann dieses in Querrichtung mit Profilierungen in Form einer Wellung ausgebildet sein. In Fig. 9 ist ein Reißband 8 gemäß Fig. 8 dargestellt, welches in Querrichtung gewellt ist und auf welches eine flächige Klebstoffschichte 9, welche für den Trennvorgang benötigt wird, aufgebracht ist. Da sich diese Klebstoffschichte 9 an die Welligkeit anpaßt, werden dessen ungeachtet die dem Stand der Technik anhaftenden Nachteile vermieden.In order to achieve the required flexibility of such a tear tape, it can be designed with profiles in the form of a corrugation in the transverse direction. FIG. 9 shows a tear tape 8 according to FIG. 8, which is corrugated in the transverse direction and to which a flat adhesive layer 9, which is required for the separation process, is applied. Since this adhesive layer 9 adapts to the ripple Nevertheless, the disadvantages inherent in the prior art are avoided.

Ein derartiges aus Papier gefertigtes Reißband kann in beliebigen Längen gefertigt werden.Such a tear tape made of paper can be made in any length.
