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 subject invention relates to a device for dividing a moving paper web, which on a Drum is wound up, thereby winding up to enable an empty drum consisting of one made of paper manufactured tear tape.

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 up in a plant for the production of Paper-made paper web on spools is required then once a coil has a given winding diameter has reached at a rate of about 25 m / second moving paper web to divide the The following paper web is wound on an empty spool to be able to continue. A tear tape is used for this, which spirally coils on the empty spool, whereby at the same time the paper web is divided along a spiral line becomes. To the tear tape at the same time as through the cutting process damaged parts of the paper web for recycling It is known to be able to feed this from paper to manufacture.

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, wie es von der WO 86 00282 A offenbart wird, die dem oberbegriff des Anspruchs 1 entspricht. 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 has great tensile strength and has to have a high rigidity, has so far been a Many side by side and glued together Laces made of paper, as described by WO 86 00282 A is disclosed, which corresponds to the preamble of claim 1. To achieve the gluing process the paper cords over their entire surface wetted with a water-soluble adhesive. Since they are in the Episode lying next to each other are pressed together, glue them together at the contact surfaces. After this The drying process of the adhesive is the one produced in this way Tear tape 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. Weiter 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 from one another, which reduces the strength of the tear tape and can also cause malfunctions 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 using such a tape for dividing 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 opened, the individual Cords at different points along the length of the Tear tape separated, which consequently also Malfunctions can be caused. Furthermore are out twisted cords manufactured tear tapes in the recycling process only difficult to resolve.

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 adhere to it such a tear tape and what to do serve to attach the tear tape to the empty spool to to be able to initiate the separation process of the paper web, on a tear tape formed by paper cords only along the outer surface lines of the paper cords, making them Adhesive layers can be removed.

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 einen mehrfach gefalteten Papierstreifen gebildet ist, wobei die aneinander liegenden Lagen des Papierstreifens miteinander zumindest partiell verklebt sind. The object of the invention is therefore based on the object to create a tear tape made of paper which the well-known, made of individual cords, Tear-off disadvantages can be avoided. This is according to the invention achieved in that the tear tape through formed a strip of paper folded several times   is, with the layers of the paper strip lying against one another are at least partially glued to one another.

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 side areas of the paper strip can be used be bent several times. Preferably the two are lateral areas of the paper strip on one side bent over. Alternatively, the two side areas of the paper strip bent over on different sides. The two side edges of the paper strip can 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 are lateral areas of the paper strip on one side bent, where they overlap and preferably the two side edges of the paper strip in the area of the two Side edges of the tear tape. Furthermore, between the at least two layers of the paper strip one by at least another paper tape-formed insert can be arranged, which is also glued to the paper strip. In particular, the insert can be a multi-layer, if necessary also folded paper strips are formed. In addition, the insert can be used on both sides Adhesive paper strips or by a strip of an 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 strips made of paper material with a long fiber orientation manufactured. To make this tear tape flexible in the transverse direction design, it can also with longitudinal grooves od. Like. Provided or corrugated in its transverse direction be.

Durch ein derartiges Reißband werden sämtliche dem bekannten Reißband anhaftenden Nachteile vermieden: With such a tear tape all the known Avoid disadvantages inherent in 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 thickness and the number of paper layers it can be made with any tensile strength and rigidity be, whereby an exact adjustment to the thickness or   Quality of the paper of the paper web that divides should be achievable. Because on the outside of the Tear tape is no glue, no gluing of the wound-up tear tape. Because rather the adhesive is only inside the tear tape, too prevents the bond from being loosened by moisture, which reduces 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, one is multi-layered, with each other by means of a water-soluble Adhesive glued paper tapes Tear tape is easier to dissolve in the recycling process and therefore it is more recyclable. In addition, such a tear tape severed along an approximately straight edge, whereby no paper residues are caused, which in Delivery channel can cause malfunctions. There further one such tear tape running straight but not has sharp longitudinal edges, this is an optimal Course guaranteed when dividing the paper web. There such a tear tape also has an approximately flat surface has, so stick on this flat layers of adhesive good thing that they cannot be replaced. Finally, one Such 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 one against the other lying layers of the paper strip by means of a water-soluble adhesive are glued together. Here the adhesive is inside the tear tape and are the outside of which 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 embodiment of FIG. 1, the tear tape is off a paper strip 1 is formed, the lateral regions 11 and 12 over the central area 10 on one side so are bent so that their longitudinal edges lie close together. The layers lying one against the other are by means of a layer 13 of an adhesive glued together. This tear tape, which is two-ply, thus has two folds formed Longitudinal edges 14 and 15 through which the separation process of 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. In Fig. 2 a tear tape according to the invention is shown, which is formed from a paper strip 2, the lateral Areas 21 and 22 above the central area 20 one above the other folded and with each other by means of adhesive layers 23 are connected, whereby a three-layer tear tape is formed, whose two side edges 24 and 25 form the separating edges. Characterized in that this tear tape is formed in three layers it is increased compared to the tear tape according to FIG. 1 Tensile strength.

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 2 in that the two lateral areas 31 and 32 of the paper tape 3 on different pages of the central region 30 are folded out. Here too are the individual layers of the paper tape 3 by means of adhesive layers 33 glued together. The two side edges 34 and 35 form the dividing 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 are the two lateral areas 41 and 42 of the paper tape 4 over the central area 40 bent several times, the individual layers of the tear tape, which has four layers, by means of adhesive layers 43 are interconnected. This will make it even higher Stiffness and tear resistance achieved. 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. In Fig. 5 a tear tape is shown, which accordingly 1 from a paper tape 1   is made, the lateral regions 11 and 12 to each other are folded. It is between the reinforcement of the tear tape the layers of paper tape 1 thus formed reinforcing paper tape 5 is provided, the width of the width the tear tape is approximately the same and which one with the layers 10, 11 and 12 of the paper tape 1 by means of two layers of adhesive 13 is connected. The insert 5 can also by a Paper carrier tape, which is coated on both sides with a water-soluble Adhesive is coated, or by a strapless Adhesive tape be formed.

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 is differs from the embodiment of FIG. 5 in that paper tape 1 three paper tapes 51 lying one above the other, 52, 53, which form a reinforcing insert, and which with the layers of the paper tape 1 by means of several Adhesive layers 13 are connected.
