Description

Die gegenständliche Erfindung betrifft eine Vorrichtung zum Auftrennen einer Papierbahn, welche auf eine erste Trommel aufgewickelt wird, und zur Einleitung der Aufwicklung dieser Papierbahn auf einer leeren, zweiten Trommel, wobei das Auftrennen der Papierbahn mittels eines Bandes od.dgl. erfolgt, dessen freies Ende mittels einer Fördereinrichtung längs einer unterhalb der Papierbahn befindlichen und quer zu dieser ausgerichteten Führungsschiene von der einen Seite der Papierbahn auf deren andere Seite bewegbar ist und auf der leeren Trommel befestigbar ist, worauf es auf dieser spiralig aufgewickelt wird, wodurch die Papierbahn aufgetrennt sowie auf die leere Trommel übergeführt wird.The present invention relates to a device for cutting a paper web, which is wound on a first drum, and for initiating the winding of this paper web on an empty, second drum, the cutting of the paper web by means of a belt or the like. takes place, the free end of which is movable by means of a conveyor along a guide rail located below and aligned transversely to this from one side of the paper web to the other side and can be fastened to the empty drum, whereupon it is wound up spirally on it, whereby the Paper web is separated and transferred to the empty drum.

Eine derartigte Vorrichtung ist aus der EU 186 659 B1 bekannt. Dabei befindet sich auf der einen Seite der Papierbahn eine Fördereinrichtung für ein aus Papierschnüren gebildetes Reißband, welches von einer Vorratstrommel abziehbar ist. Unterhalb der Papierbahn ist eine Führungsschiene angeordnet, welche sich quer zur Papierbahn von der einen Seite auf deren andere Seite erstreckt und welche mit einem nach oben offenenen und hinterschnittenen Kanal zur Aufnahme des Reißbandes ausgebildet ist. Mittels der Fördereinrichtung wird das freie Ende des Reißbandes von der einen Seite der Papierbahn auf deren andere Seite hin bewegt. Auf der anderen Seite der Papierbahn ist eine Einrichtung vorgesehen, mittels welcher das freie Ende des Reißbandes zur leeren Trommel hinbewegt wird, auf welcher es mittels einer Klebstoffbeschichtung befestigt wird. Da der in der Führungsschiene vorgesehene Kanal nach oben offen ist, wird in der Folge das Reißband aus der Führungsschiene nach oben herausgezogen und wird es auf der leeren Trommel spiralig aufgewickelt, wodurch die Papierbahn gleichfalls längs einer spiraligen Linie aufgetrennt wird und die folgende Papierbahn auf der leeren Trommel aufgewickelt wird.Such a device is known from EU 186 659 B1. There is a conveyor on one side of the paper web for a tear tape formed from paper cords, which can be pulled off a storage drum. A guide rail is arranged below the paper web, which extends transversely to the paper web from one side to the other side and which is designed with an upwardly open and undercut channel for receiving the tear tape. By means of the conveyor, the free end of the tear tape is moved from one side of the paper web to the other side. On the other side of the paper web, a device is provided, by means of which the free end of the tear tape is moved towards the empty drum, on which it is attached by means of an adhesive coating. As the channel provided in the guide rail is open at the top, the tear tape is subsequently pulled out of the guide rail and wound up spirally on the empty drum, whereby the paper web is also split along a spiral line and the following paper web on the empty drum is wound up.

Diese bekannte Vorrichtung weist jedoch eine Mehrzahl von Nachteilen auf. Einerseits muß das Reißband die erforderliche Steifigkeit aufweisen, um mittels der Fördereinrichtung längs des in der Führungsschiene befindlichen Kanals von der einen Seite der Papierbahn auf deren andere Seite geschoben werden zu können. Andererseits besteht aufgrund dessen, daß der in der Führungsschiene vorgesehene Kanal auf die Breite des Papierbandes abgestimmt sein muß, das Erfordernis, entweder für unterschiedlich breite Reißbänder unterschiedliche Führungsschienen vorzusehen, wodurch der Fertigungsaufwand erhöht wird, oder das Erfordernis, unabhängig von den technischen Gegebenheiten, nämlich der unterschiedlichen Breiten und der unterschiedlichen Stärken der Papierbahnen immer gleich breite Reißbänder einzusetzen. Dies bedingt jedoch das Erfordernis, unabhängig von der Betriebsart jeweils ein Reißband mit maximaler Zugfestigkeit einzusetzen.However, this known device has a number of disadvantages. On the one hand, the tear tape must have the required rigidity in order to be able to be pushed from one side of the paper web to the other side by means of the conveying device along the channel located in the guide rail. On the other hand, due to the fact that the channel provided in the guide rail must be matched to the width of the paper tape, there is the need either to provide different guide rails for tear strips of different widths, which increases the manufacturing outlay, or the requirement, regardless of the technical circumstances, namely the different widths and the different thicknesses of the paper webs always use the same width tear tapes. However, this necessitates the use of a tear tape with maximum tensile strength, regardless of the operating mode.

Weiters wird bei der bekannten Vorrichtung das Reißband beim Trennvorgang aus dem hinterschnittenen Kanal nach oben hinausgerissen, wodurch es geschwächt werden kann, was bei dessen Dimensionierung berücksichtigt werden muß. Weiters können im Kanal Reste des Reißbandes verbleiben, wodurch bei einem folgenden Trennvorgang der Transport des Reißbandes durch den Kanal hindurch behindert wird. Demnach besteht bei der bekannten Vorrichtung das Erfordernis, den Kanal für die Führung des Reißbandes periodisch zu reinigen, um aufgrund von Verstopfungen bedingte Funktionsstörungen aussschließen zu können.Furthermore, in the known device, the tear tape is torn out of the undercut channel during the separating process, as a result of which it can be weakened, which must be taken into account when dimensioning it. Furthermore, remnants of the tear tape can remain in the channel, whereby the transport of the tear tape through the channel is hindered in a subsequent separation process. Accordingly, in the known device, there is a need to periodically clean the channel for guiding the tear tape in order to be able to rule out malfunctions caused by blockages.

Der gegenständlichen Erfindung liegt demnach die Aufgabe zugrunde, eine Vorrichtung zu schaffen, durch welche die der bekannten Vorrichtung anhaftenden Nachteile vermieden werden. Dies wird erfindungsgemäß dadurch erzielt, daß längs der Führungsschiene ein Schlitten geführt ist, welcher mit einer Halteeinrichtung für das Reißband od.dgl. ausgebildet ist, wodurch dessen freies Ende von der einen Seite der Papierbahn auf deren andere Seite förderbar ist.The object of the invention is therefore to provide a device by which the disadvantages inherent in the known device are avoided. This is achieved according to the invention in that a slide is guided along the guide rail, or the like with a holding device for the tear tape. is trained, whereby its free end can be conveyed from one side of the paper web to the other side.

In particular, the second clamping jaw on the carrier can be pivoted against the action of a return spring with respect to the first clamping jaw.

Nach einer bevorzugten Ausführungsform ist der Schlitten innerhalb der Führungsschiene geführt, wobei die Führungsschiene mit einem Schlitz ausgebildet ist, welcher von einem Träger für die Halteeinrichtung durchsetzt ist. Weiters ist vorzugsweise die Führungsschiene unterhalb der Papierbahn von einem Gehäuse umgeben, in dessen Innenraum sich die Führungsschiene befindet. Dabei ist dieses Gehäuse auf derjenigen Seite, welche der leeren Spule zugewandt ist, mittels einer abschwenkbaren Klappe verschlossen.According to a preferred embodiment, the slide is guided within the guide rail, the guide rail being formed with a slot which is penetrated by a carrier for the holding device. Furthermore, the guide rail is preferably surrounded below the paper web by a housing, in the interior of which the guide rail is located. This housing is closed on the side facing the empty spool by means of a hinged flap.

Nach weiteren bevorzugten Ausführungsformen befindet sich der Schlitz der Führungsschiene, welcher vom Träger für die Halteeinrichtung durchragt ist, auf einer ersten Seite, befindet sich die Halteeinrichtung angenähert unterhalb der Schiene, wobei sie zur anderen Seite hin öffenbar ist, und befindet sich die öffenbare Klappe auf der anderen Seite des Gehäuses.According to further preferred embodiments, the slot of the guide rail, which is penetrated by the support for the holding device, is located on a first side, the holding device is located approximately below the rail, wherein it can be opened to the other side, and the openable flap is open the other side of the case.

Vorzugsweise ist die Führungsschiene an einer Tragschiene befestigt, welche sich unterhalb der Papierbahn erstreckt. Weiter ist vorzugsweise der Schlitten längs der Führungsschiene mittels eines Seiles od.dgl. bewegbar. Dabei kann das Seil in sich geschlossen sein, wobei ein Trum innerhalb der Führungsschiene und das andere Trum innerhalb der Tragschiene geführt ist.The guide rail is preferably fastened to a mounting rail which extends below the paper web. Furthermore, the slide is preferably or the like along the guide rail by means of a rope. movable. The rope can be self-contained, one strand being guided within the guide rail and the other strand being guided within the carrier rail.

Nach weiteren bevorzugten Merkmalen ist die Halteeinrichtung durch zwei Klemmbacken gebildet, welche als am Träger verdrehbar gelagerte Walzen ausgebildet sind, wobei eine derselben mit einer Rücklaufsperre ausgebildet ist und weiters eine derselben antreibbar ist. Hierfür kann eine dieser beiden Walzen mit einem Kegelrad ausgebildet sein, welches mit einem Drehantrieb kuppelbar ist.According to further preferred features, the holding device is formed by two clamping jaws, which can be rotated on the carrier mounted rollers are formed, one of which is formed with a backstop and further one of the same is drivable. For this purpose, one of these two rollers can be designed with a bevel gear which can be coupled to a rotary drive.

Vorzugsweise sind im Bereich der Führungsschiene, wo diese nicht vom Gehäuse umschlossen ist, Bügel vorgesehen, welche mit verstellbaren, insbesondere elastischen Klappen ausgebildet sind.Brackets are preferably provided in the region of the guide rail, where it is not enclosed by the housing, which are designed with adjustable, in particular elastic flaps.

Eine erfindungsgemäße Vorrichtung wird bei einer Anlage zum Aufspulen einer Papierbahn, welche am Ende einer Papiererzeugungsanlage vorgesehen ist, eingesetzt. Diese Vorrichtung weist ein Traggestell 1 für eine erste Trommel 11 auf, welche an eine Antriebstrommel 13 anliegt und auf welche die von der Papiererzeugungsanlage einlangende Papierbahn 10, welche über eine Führungswalze 15 zugeführt wird, aufgewickelt wird. Weiters ist eine verschwenkbare Trageinrichtung 14 für eine zweite Trommel 12 vorgesehen, auf welche die Papierbahn 10 dann aufgewickelt wird, sobald die erste Trommel 11 den angestrebten Wickeldurchmesser erreicht hat. Um beim Vorgang des Aufwickelns von der ersten Trommel 11 auf die zweite Trommel 12 übergehen zu können, muß die Papierbahn 10 aufgetrennt werden.A device according to the invention is used in a system for winding up a paper web, which is provided at the end of a paper production system. This device has a support frame 1 for a first drum 11, which bears against a drive drum 13 and onto which the paper web 10 arriving from the paper production system passes over a guide roller 15 is fed, is wound. Furthermore, a pivotable support device 14 is provided for a second drum 12, onto which the paper web 10 is then wound as soon as the first drum 11 has reached the desired winding diameter. In order to be able to pass from the first drum 11 to the second drum 12 during the winding operation, the paper web 10 must be separated.

Hiezu dient ein Reißband 20, dessen freies Ende von einem Gerät 2, welches sich auf der einen Seite der Papierbahn 10 befindet, mittels einer Fördervorrichtung 3 von dieser Seite der Papierbahn 10 auf deren andere Seite hin gefördert wird. Sobald der Vorgang der Auftrennung der Papierbahn 10 eingeleitet werden soll, wird das Reißband 20 mittels einer auf diesem befindlichen Klebstoffbeschichtung auf der leeren Trommel 12 befestigt, wodurch es auf dieser spiralig aufgewickelt wird. Dabei wird das Reißband 20 aus der Fördereinrichtung 3 bis zu einem Bügel 59 herausgerissen. Hierdurch wird die Papierbahn 10 gleichfalls spiralig auftrennt. Gleichzeitig wird die vordere Reißkante der Papierbahn 10 an die leere Trommel 12 zur Anlage gebracht, wodurch in der Folge die Papierbahn 10 auf der zweiten Trommel 12 aufgewickelt wird. Hierauf wird die erste Trommel 11, welche den angestrebten Wickeldurchmesser erreicht hat, entfernt, wird an deren Stelle die zweite Trommel 12 angeordnet, welche durch Anlage an die Antriebstrommel 13 in Rotation gehalten wird, und wird in die Trageinrichtung 14 eine weitere leere Trommel eingesetzt.A tear tape 20 is used for this purpose, the free end of which is conveyed by a device 2, which is located on one side of the paper web 10, by means of a conveying device 3 from this side of the paper web 10 to the other side thereof. As soon as the process of separating the paper web 10 is to be initiated, the tear tape 20 is fastened to the empty drum 12 by means of an adhesive coating thereon, as a result of which it is wound spirally thereon. The tear tape 20 is torn out of the conveyor 3 to a bracket 59. As a result, the paper web 10 is also cut spirally. At the same time, the front tear edge of the paper web 10 is brought into contact with the empty drum 12, as a result of which the paper web 10 is subsequently wound on the second drum 12. Then the first drum 11, which has reached the desired winding diameter, is removed, the second drum 12 is arranged in its place, which is kept in rotation by contact with the drive drum 13, and another empty drum is inserted into the carrying device 14.

Mit einer derartigen Anlage kann demnach die von der Papiererzeugungsanlage z.B. mit einer Geschwindigkeit von 25m/sek. zugeführte Papierbahn 10 kontinuierlich auf Trommeln aufgewickelt werden. Sobald die erste Trommel 11 den vorgesehenen Wickeldurchmesser erreicht hat, wird die Papierbahn 10 aufgetrennt, erfolgt der Übergang des Aufwickelns auf die leere, zweite Trommel 12 und wird die volle Trommel abtransportiert.With such a system, the paper production system can therefore, for example, at a speed of 25 m / sec. fed paper web 10 are continuously wound on drums. As soon as the first drum 11 has reached the intended winding diameter, the paper web 10 is separated, the transition from winding to the takes place empty, second drum 12 and the full drum is removed.

Das Reißband 20 wird mittels des Gerätes 2 von einer Vorratstrommel 21 abgezogen und der Fördereinrichtung 3, durch welche das freie Ende des Reißbandes 20 von der einen Seite der Papierbahn 10 auf deren andere Seite bewegt wird, zugeführt. Im Gerät 2 wird weiters auf das vordere freie Ende des Reißbandes 20 ein Klebstoff aufgebracht, der dazu dient, das Reißband 20 an der leeren Trommel 12 zu befestigen, um den Trennvorgang einleiten zu können. Am Gerät 2 befindet sich ein Gehäuse 22, in welchem für den Trennvorgang erforderliche Schlaufen des Reißbandes 20 gebildet werden. Zudem sind im Gerät 2 eine Bremseinrichtung und eine Schneidvorrichtung für das Reißband 20 enthalten. An das Gerät 2 schließt die Fördereinrichtung 3 an, welche nachstehend anhand der Fig. 2 erläutert ist.The tear tape 20 is drawn off from a storage drum 21 by means of the device 2 and fed to the conveyor 3, through which the free end of the tear tape 20 is moved from one side of the paper web 10 to the other side. In the device 2, an adhesive is also applied to the front free end of the tear tape 20, which is used to attach the tear tape 20 to the empty drum 12 in order to be able to initiate the separation process. On the device 2 there is a housing 22 in which loops of the tear tape 20 required for the separation process are formed. In addition, the device 2 includes a braking device and a cutting device for the tear tape 20. The conveyor 3 connects to the device 2, which is explained below with reference to FIG. 2.

Die Fördereinrichtung 3 weist eine Tragschiene 31 auf, an welcher mittels einer nach unten abragenden U-förmigen Leiste 32 mittels Bolzen 33 eine Führungsschiene 34 lösbar befestigt ist. Die Führungsschiene 34 ist mit einem zylindrischen Kanal 35 ausgebildet, innerhalb dessen ein zylindrischer Schlitten 36 geführt ist. Vom Schlitten 36 ragen seitlich nach außen zwei Zapfen 37 ab, welche einen in der Führungsschiene 34 befindlichen Schlitz 38 durchragen und an welchen ein Träger 40 für zwei Klemmbacken 41 und 42 befestigt ist. Der obere Klemmbacken 41 ist mit dem Träger 40 starr verbunden. Demgegenüber ist der untere Klemmbacken 42 am Träger 40 um einen Zapfen 43 entgegen der Wirkung einer Rückstellfeder 44 verschwenkbar gelagert. In Bewegungsrichtung des Reißbandes 20 vor den beiden Klemmbacken 41 und 42 befindet sich ein Bügel 45, innerhalb desssen das Reißband 20 geführt ist und welcher entgegen der Wirkung einer Feder 46 um den Bolzen 43 nach oben verschwenkbar ist. Der Schlitten 36 ist mittels eines in sich geschlossenen Zugseiles 30 im Kanal 35 der Führungsschiene 34 bewegbar. Dabei ist das eine Trum des Zugseiles 30 im Kanal 35 der Führungsschiene 34 geführt und ist das andere Trum in einem in der Tragschiene 31 angeordneten Schlauch 30a in der Art eines Powdenzuges geführt. Die beiden Klemmbacken 41 und 42 sind durch verdrehbare Walzen gebildet. Eine der beiden Walzen, insbesondere die obere Walze 41, ist mit einer Rücklaufsperre ausgebildet. Zudem ist die obere Walze 41 mittels einer Welle mit einem Kegelrad 48 auf Mitnahme gekuppelt.
An der Tragschiene 31 ist ein Gehäuse 49 befestigt, welches die Führungsschiene 34 und den Träger 40 umschließt und welches an der den Trommeln 11 und 12 zugewandten Seite mittels einer Klappe 50 aus einem elastisch verformbaren Material verschlossen ist.The conveying device 3 has a support rail 31, on which a guide rail 34 is detachably fastened by means of a U-shaped bar 32 projecting downwards by means of bolts 33. The guide rail 34 is formed with a cylindrical channel 35, within which a cylindrical slide 36 is guided. Two pins 37 protrude laterally from the slide 36, which protrude through a slot 38 in the guide rail 34 and to which a carrier 40 for two clamping jaws 41 and 42 is fastened. The upper jaw 41 is rigidly connected to the carrier 40. In contrast, the lower jaw 42 is pivotally mounted on the carrier 40 about a pin 43 against the action of a return spring 44. In the direction of movement of the tear tape 20 in front of the two jaws 41 and 42 there is a bracket 45 within which the tear tape 20 is guided and which can be pivoted upward about the bolt 43 against the action of a spring 46. The carriage 36 is in the channel 35 of the guide rail by means of a self-contained pull cable 30 34 movable. One strand of the pull cable 30 is guided in the channel 35 of the guide rail 34 and the other strand is guided in a hose 30a arranged in the support rail 31 in the manner of a Powden cable. The two clamping jaws 41 and 42 are formed by rotatable rollers. One of the two rollers, in particular the upper roller 41, is designed with a backstop. In addition, the upper roller 41 is coupled to be entrained by means of a shaft with a bevel gear 48.
A housing 49 is fastened to the mounting rail 31, which encloses the guide rail 34 and the carrier 40 and which is closed on the side facing the drums 11 and 12 by means of a flap 50 made of an elastically deformable material.

In der Ausgangsstellung befinden sich der Schlitten 34 und damit der Träger 40 mit den Klemmbacken 41 und 42 auf derjenigen Seite der Vorrichtung, auf welcher sich das Gerät 2 befindet. In diesem Bereich, welcher in den Fig. 3a und 3b dargestellt ist, ist ein dem Träger 40 zugeordneter Steuerzylinder 23 vorgesehen, durch dessen Kolben 24 die untere Walze 42 entgegen der Wirkung der Feder 44 nach unten abschwenkbar ist. In der abgeschwenkten Lage dieser Walze 42 kann zwischen den beiden als Klemmbacken dienenden Walzen 41 und 42 das Reißband 20 hindurchgefördert werden, wobei dessen freies Ende, welches mit einer Klebstoffbeschichtung versehen ist, sich außerhalb der beiden Klemmbacken 41 und 42 befindet, wodurch die Klebstoffschichte nicht beschädigt wird.In the starting position, the carriage 34 and thus the carrier 40 with the clamping jaws 41 and 42 are on the side of the device on which the device 2 is located. In this area, which is shown in FIGS. 3a and 3b, a control cylinder 23 assigned to the carrier 40 is provided, by means of the piston 24 of which the lower roller 42 can be pivoted downward against the action of the spring 44. In the pivoted-down position of this roller 42, the tear tape 20 can be conveyed between the two rollers 41 and 42 serving as clamping jaws, the free end of which, which is provided with an adhesive coating, being located outside the two clamping jaws 41 and 42, as a result of which the adhesive layer does not is damaged.

Wie dies aus Fig.4 ersichtlich ist, ist die Führungsschiene 34 auf der anderen Seite der Papierbahn 10 mit einer räumlichen Krümmung ausgebildet, wobei sie in einer Trageinrichtung 52, welche an einem Gestell 51 vorgesehen ist, endet. Mittels dieser Trageinrichtung 52 ist das zwischen den beiden Klemmbacken 41 und 42 erfaßte Reißband 20 so gehalten, daß dessen freies Ende 20a auf die leere Trommel 12 hin ausgerichtet ist. Da das Gehäuse 49 im Bereich des linken Randes der Papierbahn 10 endet und das Reißband 20 im Bereich der Krümmung der Führungsschiene 34 einer Führung bedarf, sind hierfür mehrere Bügel 55 vorgesehen, welche das Reißband 20 umschließen. Der Trageinrichtung 52 ist weiters ein Antrieb 57 zugeordnet, welcher über eine flexible Welle 58 an ein Antriebsrad 56 geführt ist, welches mit dem Kegelrad 48 kuppelbar ist.As can be seen from FIG. 4, the guide rail 34 is formed on the other side of the paper web 10 with a spatial curvature, it ending in a support device 52, which is provided on a frame 51. By means of this support device 52, the tear tape 20 gripped between the two clamping jaws 41 and 42 is held in such a way that its free end 20a points towards the empty drum 12 is aligned. Since the housing 49 ends in the area of the left edge of the paper web 10 and the tear tape 20 needs a guide in the area of the curvature of the guide rail 34, several brackets 55 are provided for this purpose, which enclose the tear tape 20. The support device 52 is also assigned a drive 57 which is guided via a flexible shaft 58 to a drive wheel 56 which can be coupled to the bevel gear 48.

In Fig. 5 ist der Verlauf der Führungsschiene 34 und des Reißbandes 20 in Richtung der Achsen der Trommeln 12 und 13 dargestellt. Wie daraus ersichtlich ist, verläuft die Führungsschiene 34 in einer Krümmung nach oben und in der Folge in einer Krümmung außerhalb der Antriebstrommel 13. Das Reißband 20, welches mittels des Schlittens 36 längs der Führungsschiene 34 gefördert wird, folgt diesem Verlauf, wobei es innerhalb der Bügel 55 geführt ist. An der Trageinrichtung 52 ist weiters eine Umlenkrolle 60 für das Förderseil 30 gelagert.
Wie dies aus Fig.6 ersichtlich ist, sind die Bügel 55, welche an der Führungsbahn 34 befestigt sind, mit zwei elastisch verformbaren Klappen 55a und 55b ausgebildet.
Wie dies insbesondere aus Fig. 7 ersichtlich ist, kommt am Ende der Führungsschiene 34 das Kegelrad mit dem Antriebsrad 56 in Eingriff. Sämtliche diese Details sind auch in den Fig. 8a und 8b dargestellt.5 shows the course of the guide rail 34 and the tear tape 20 in the direction of the axes of the drums 12 and 13. As can be seen from this, the guide rail 34 runs upward in a curve and subsequently in a curve outside the drive drum 13. The tear tape 20, which is conveyed along the guide rail 34 by means of the carriage 36, follows this course, being within the Bracket 55 is guided. A deflection roller 60 for the conveyor cable 30 is also mounted on the support device 52.
As can be seen from FIG. 6, the brackets 55, which are fastened to the guideway 34, are designed with two elastically deformable flaps 55a and 55b.
7, the bevel gear comes into engagement with the drive gear 56 at the end of the guide rail 34. All of these details are also shown in FIGS. 8a and 8b.

Die Wirkungsweise dieser Vorrichtung ist wie folgt:
Mittels des Gerätes 2 wird von der Vorratsspule 21 ein Reißband 20 abgezogen, dessen vorderes freies Ende 20a im Gerät 2 an der Oberseite mit Klebstoff beschichtet wird. Hierauf wird das vordere freie Ende 20a des Reißbandes 20 zwischen den beiden Klemmbacken 41 und 42, welche sich in der ersten Endstellung des Schlittens 36 bzw. des Trägers 40, welche in Fig. 3b dargestellt ist, in Offenstellung befinden, hindurchgeführt. In der Folge werden die beiden Klemmbacken 41 und 42 mittels des Stellzylinders 23 in ihre Schließstellung gebracht, wodurch das Reißband 20 hinter der Klebeschichte 20a erfaßt wird, und wird der Schlitten 36 mittels des Seiles 30 von der einen Seite der Papierbahn 10 auf deren andere Seite gefördert, wobei das Reißband 20 nachgezogen wird. Das Reißband 20 befindet sich dabei in leicht gespanntem Zustand innerhalb des Gehäuses 49. Der Schlitten 36 wird weiter bis zur Trageinrichtung 52 bewegt und zieht das Reißband 20 mit. An dieser Stelle ist das freie Ende 20a des Reißbandes 20 auf die leere Spule 12 hin ausgerichtet, wobei sich die Klebeschichte an dessen Oberseite befindet.The operation of this device is as follows:
By means of the device 2, a tear tape 20 is pulled off the supply reel 21, the front free end 20a of which is coated in the device 2 on the top with adhesive. The front free end 20a of the tear tape 20 is then passed between the two clamping jaws 41 and 42, which are in the first end position of the slide 36 or the carrier 40, which is shown in FIG. 3b, in the open position. As a result, the two clamping jaws 41 and 42 are brought into their closed position by means of the actuating cylinder 23, as a result of which the tear tape 20 is gripped behind the adhesive layer 20a, and the carriage 36 is moved from one side of the paper web 10 to the other side by means of the cable 30 promoted, the tear tape 20 is pulled. The tear tape 20 is in a slightly tensioned state within the housing 49. The slide 36 is moved further to the support device 52 and pulls the tear tape 20 with it. At this point, the free end 20a of the tear tape 20 is aligned with the empty spool 12, the adhesive layer being on the top thereof.

Sobald die Papierbahn 10 aufgetrennt werden soll, wird die leere Trommel 12 mittels eines dieser zugeordneten Antriebes auf die Rotationsgeschwindigkeit der ersten Trommel 11 gebracht. Hierauf wird die Trageinrichtung 14 im Uhrzeigersinn verschwenkt, wodurch die Trommel 12 an der Antriebstrommel 13 zur Anlage kommt und von dieser in Rotation gehalten wird. Sobald hierauf das freie Ende 20a des Reißbandes 20 mittels des Antriebes 57 und über das Kegelrad 48 auf die Trommel 12 hin bewegt wird, bleibt es aufgrund der Beschichtung mit Klebstoff auf dieser haften und wird es von dieser nachgezogen. Hierdurch wird das Reißband 20 aus den beiden Klemmbacken 41 und 42 herausgerissen, wobei der Bügel 45 entgegen der Wirkung der Feder 46 nach oben ausgeschwenkt wird und das Reißband 20 freigibt. Zudem wird das Reißband 20 auch aus den Bügeln 55, deren elastische Klappen 55a und 55b sich öffnen, ebenso wie aus dem Gehäuse 49, dessen elastische Klappe 50 sich gleichfalls öffnet, bis zum Bügel 59 herausgerissen und wird es auf der Trommel 12 spiralig aufgewickelt. Dabei werden die vorher gebildeten Schlaufen aufgebraucht. Schließlich wird das Reißband 20 abgeschnitten. Die Bewegung des Reißbandes 20 wird durch die elastastischen Klappen 55a und 55b der Bügel 55, durch die elastische Klappe 50 des Gehäuses 49 und durch die im Gerät 2 befindliche Bandbremse gebremst. Hierdurch werden stoßartige Bewegungen des Reißbandes 20 vermieden.As soon as the paper web 10 is to be separated, the empty drum 12 is brought to the rotational speed of the first drum 11 by means of a drive assigned to it. The support device 14 is then pivoted clockwise, as a result of which the drum 12 comes into contact with the drive drum 13 and is held in rotation by the latter. As soon as the free end 20a of the tear tape 20 is then moved onto the drum 12 by means of the drive 57 and via the bevel gear 48, it remains adhering to the drum 12 due to the coating with adhesive and is pulled by the latter. As a result, the tear tape 20 is torn out of the two jaws 41 and 42, the bracket 45 being pivoted upward against the action of the spring 46 and releasing the tear tape 20. In addition, the tear tape 20 is also torn out of the brackets 55, whose elastic flaps 55a and 55b open, as well as from the housing 49, whose elastic flap 50 also opens, up to the bracket 59 and is spirally wound on the drum 12. The loops previously formed are used up. Finally, the tear tape 20 is cut off. The movement of the tear tape 20 is by the elastic flaps 55a and 55b of the bracket 55, by the elastic flap 50 of the housing 49 and by the band brake located in the device 2 slowed down. This avoids jerky movements of the tear tape 20.

Mit dem spiraligen Aufwickeln des Reißbandes 20 auf der Trommel 12 wird die Papierbahn 10 gleichfalls spiralig aufgetrennt und wird deren vordere Reißkante an die Trommel 12 zur Anlage gebracht, wodurch die weitere Papierbahn 10 auf der Trommel 12 aufgewickelt wird. Hierauf wird die volle Trommel 11 entfernt, wird an deren Stelle die leere Trommel 12 angeordnet, wird die Trageinrichtung 14 zurückverschwenkt und wird in diese eine leere Trommel eingsetzt. Zudem wird der Schlitten 36 in seine Ausgangsposition zurückverstellt und wird das vordere Ende des folgenden Reißbandes 20, nachdem es mit Klebstoff beschichtet worden ist, mittels der Fördervorrichtung wieder auf die andere Seite der Papierbahn 10 bewegt. Somit ist die Vorrichtung für einen erneuten Reißvorgang und den Beginn des Wickelvorganges auf eine leere Spule vorbereitet.With the spiral winding of the tear tape 20 on the drum 12, the paper web 10 is also spirally separated and its front tear edge is brought into contact with the drum 12, whereby the further paper web 10 is wound on the drum 12. The full drum 11 is then removed, the empty drum 12 is arranged in its place, the carrying device 14 is pivoted back and an empty drum is inserted into it. In addition, the carriage 36 is moved back to its starting position and the front end of the following tear tape 20, after it has been coated with adhesive, is moved again to the other side of the paper web 10 by means of the conveyor device. The device is thus prepared for a new tearing process and the start of the winding process on an empty spool.

Da mittels einer derartigen Vorrichtung jegliche Arten von Reißelementen von der einen Seite der Papierbahn auf deren andere Seite bewegbar sind, können die Reißbänder auf die Breite der Papierbahn bzw. auf die Festigkeit des Papiers abgestimmt werden. Maßgeblich ist nur die aufgrund der Papierbahn erforderliche Zugfestigkeit des Reißelementes. Anstelle von Reißbändern können auch Reißseile eingesetzt werden.Since any type of tear elements can be moved from one side of the paper web to the other side by means of such a device, the tear tapes can be matched to the width of the paper web or to the strength of the paper. The only decisive factor is the tensile strength of the tear element due to the paper web. Ropes can also be used instead of tear tapes.
