Die gegenständliche Erfindung betrifft eine Einrichtung zur Unterteilung einer auf einer Trommel aufwickelbaren Papierbahn, bestehend aus einem aus einem Kunststoffmaterial gefertigten Reißband, welches auf der leeren Trommel wendelförmig aufgewickelt wird, wodurch es die Papierbahn längs einer wendelförmigen Linie unterteilt.The present invention relates to a device for dividing a paper web that can be wound on a drum, consisting of a tear tape made of a plastic material, which is wound helically on the empty drum, whereby it divides the paper web along a helical line.
Es ist bekannt, Papierbahnen, welche auf einer Trommel aufgewickelt werden, mittels Reißbändern, die auf der leeren Trommel wendelförmig aufgewickelt werden, zu unterteilen, um die Papierbahn in weiterer Folge auf einer leeren Spule aufwickeln zu können. Da die Reißbänder eine sehr hohe Zugfestigkeit aufweisen müssen, ist es bekannt, diese aus miteinander verklebten Papierschnüren herzustellen. Aus der EU 727 376 A2 ist weiters ein Reißband bekannt, welches durch ein gefalztes, mehrlagiges Papierband gebildet ist.It is known to divide paper webs which are wound on a drum by means of tear tapes which are wound helically on the empty drum in order to be able to subsequently wind the paper web on an empty spool. Since the tear tapes must have a very high tensile strength, it is known to produce them from paper cords glued together. From EU 727 376 A2 a tear tape is also known, which is formed by a folded, multi-layer paper tape.
Bekannte, aus Papier gefertigte Reißbänder sind deshalb vorteilhaft, weil sie zugleich mit den Papierabfällen einer Wiederverwertung zugeführt werden können. Diesen bekannten Reißbändern haftet jedoch der Nachteil an, daß sie zur Gewährleistung der erforderlichen Zugfestigkeit eine Dicke in der Größenordnung von mindestens etwa 1,5 mm aufweisen müssen. Da derartige Reißbänder auf die leere Trommel wendelförmig aufgewickelt werden und über diese Reißbänder in weiterer Folge die Papierbahn aufgewik-kelt wird, bedingt jedoch die relativ große Dicke des Reißbandes, daß in einer Vielzahl von Lagen der auf die Trommel aufgewickelten Papierbahn durch das Reißband Einprägungen verursacht werden, wodurch das Papier den Anforderungen an Qualität nicht entspricht, sondern vielmehr einen Ausschuß darstellt.Known tear tapes made of paper are advantageous because they can be recycled with the paper waste. However, these known tear tapes have the disadvantage that they must have a thickness of the order of magnitude of at least about 1.5 mm in order to ensure the required tensile strength. Since such tear tapes are wound helically on the empty drum and the paper web is subsequently wound over these tear tapes, the relatively large thickness of the tear tape, however, means that the tear tape causes impressions in a plurality of layers of the paper web wound on the drum which means that the paper does not meet the quality requirements, but rather represents a committee.
Es ist weiters auch bekannt, Reißbänder aus einem Kunststoffmaterial herzustellen. Bekannte derartige Reißbänder sind jedoch deshalb nachteilig, da sie einer Dehnung unterliegen, weswegen durch sie dem Erfordernis, die Papierbahn unter Spannung zu fixieren und diese längs einer wendelförmigen Linie aufzutrennen, nicht entsprochen wird.It is also known to produce tear tapes from a plastic material. Known such tear tapes are disadvantageous, however, because they are subject to stretching, which is why they do not meet the need to fix the paper web under tension and to tear it open along a helical line.
Der gegenständlichen Erfindung liegt somit die Aufgabe zugrunde, ein Reißband zu schaffen, welches einerseits sehr dünn ist, wodurch Beschädigungen der Papierbahn ausgeschlossen werden, und welches andererseits nicht dehnbar ist, wodurch die Papierbahn unter Spannung fixierbar ist. Dies wird erfindungsgemäß dadurch erzielt, daß das Reißband aus einem vorgereckten Polyamid oder aus einer Vielzahl von aus Polyesterfasern bestehenden Schnüren hergestellt ist und eine Dicke von maximal 0,6 mm aufweist. Vorzugsweise ist das Reißband aus einer Folie aus extrudiertem und vorgerecktem Polyamid geschnitten. Dabei kann das Reißband eine Dicke von 0,1 mm bis 0,3 mm und eine Breite von 15 mm bis 25 mm, vorzugsweise von 19 mm, aufweisen. Zudem können die Kanten des Reißbandes abgefast oder abgerundet sein.The object of the present invention is therefore to provide a tear tape which is very thin on the one hand, which prevents damage to the paper web, and which on the other hand is not stretchable, as a result of which the paper web can be fixed under tension. This is achieved according to the invention in that the tear tape is made from a pre-stretched polyamide or from a large number of cords made of polyester fibers and has a maximum thickness of 0.6 mm. The tear tape is preferably cut from a film of extruded and pre-stretched polyamide. The tear tape can have a thickness of 0.1 mm to 0.3 mm and a width of 15 mm to 25 mm, preferably 19 mm. In addition, the edges of the tear tape can be chamfered or rounded.

Fig. 4b das Detail D der Fig. 4, in vergrößertem Maßstab,4b, the detail D of FIG. 4, on an enlarged scale,
In der Fig. 1 und 1a ist ein Reißband 1 dargestellt, welches aus einer extrudierten, vorgereckten Polyamidfolie geschnitten ist, wodurch es, wie dies aus Fig. 1 b ersichtlich ist, scharfkantig ausgebildet ist.1 and 1a, a tear tape 1 is shown, which is cut from an extruded, pre-stretched polyamide film, whereby, as can be seen from Fig. 1b, it is formed with sharp edges.
Die Dicke d dieses Reißbandes beträgt 0,1 mm bis 0,6 mm, vorzugsweise 0,1 mm bis 0,3 mm. Die Breite b dieses Reißbandes 1 beträgt 15 mm bis 25 mm, vorzugsweise 19 mm. Die Zugfestigkeit dieses Reißbandes 1 beträgt mindestens 120 kg. Die Dehnung kann maximal 8 % betragen.The thickness d of this tear tape is 0.1 mm to 0.6 mm, preferably 0.1 mm to 0.3 mm. The width b of this tear tape 1 is 15 mm to 25 mm, preferably 19 mm. The tensile strength of this tear tape 1 is at least 120 kg. The stretch can be a maximum of 8%.
Ein aus extrudiertem, vorgerecktem Polyamid gefertigtes Reißband ist einerseits hinreichend steif, daß es auf eine leere Trommel aufgebracht werden kann. Es ist zudem hinreichend elastisch, um sich an die Trommel dicht anzulegen. Da es eine sehr geringe Dicke aufweist, werden nur wenige Lagen der darüber gewickelten Papierbahn mit Einprägungen versehen, wodurch der auftretende Ausschuß sehr gering ist. Da dieses Reißband 1 hinreichend zugfest ist, kann es trot2 seiner geringen Dicke die bestimmungsgemäße Funktion erfüllen, ohne daß die Gefahr besteht, daß es reißt.A tear tape made from extruded, pre-stretched polyamide is on the one hand sufficiently stiff that it can be applied to an empty drum. It is also sufficiently elastic to fit tightly against the drum. Since it has a very small thickness, only a few layers of the paper web wound over it are provided with impressions, as a result of which the reject that occurs is very small. Since this tear tape 1 has sufficient tensile strength, it can, despite its small thickness, fulfill its intended function without the risk of it tearing.
Bei unterschiedlichen Dicken der Papierbahn können dabei auch Reißbänder mit unterschiedlichen Dicken zur Anwendung gebracht werden. 2With different thicknesses of the paper web, tear tapes with different thicknesses can also be used. 2nd
