Description

Die Erfindung betrifft eine Vorrichtung zum Splicen von Bah­nen, insbesondere von Papierbahnen für die Herstellung von Wellpappe mit den Merkmalen des Oberbegriffs des Pa­tentanspruches 1.The invention relates to a device for splicing webs, in particular paper webs for the production of corrugated cardboard, with the features of the preamble of claim 1.

Eine derartige Vorrichtung ist aus der DE-0S 21 29 903 und DE-0S 23 30 945 bekannt. Hierbei wird die ablaufende Bahn über eine Umlenkwalze zu einer Speichervorrichtung geleitet, die überhalb dem Abrollgestell für die Bahnrollen angeordnet ist. Die vorbereite, mit der ablaufenden Bahn zu verbindende weitere Bahn wird an einer daneben angeordneten Walze durch Saugdüsen festgehalten. Das Ende dieser vorbereiteten Bahn ist mit einem beidseitigen Klebeband versehen. Zum Verbinden der beiden Bahnen wird die die vorbereitete Bahn festhal­tende Haltewalze an die Umlenkwalze für die ablaufende Bahn angepreßt. Ein Messer schneidet die weiterhin abgezogenen verbundenen Bahnen hinter der Walze für die ablaufende Bahn ab. Nachteilig ist hierbei, daß die Verbindung der beiden Bahnen eine Restfahne aufweist. Dies führt zu Schwierigkei­ten im weiteren Bahnablauf. Außerdem ist die Klebeverbindung nur einem verhältnismäßige kurzem Andruck ausgesetzt. Es be­steht die Gefahr von Bahnabrissen.Such a device is known from DE-0S 21 29 903 and DE-0S 23 30 945. Here, the running web is passed over a deflection roller to a storage device which is arranged above the unwinding frame for the web rolls. The further web, which is ready to be connected to the running web, is held on an adjacent roller by suction nozzles. The end of this prepared web is covered with double-sided adhesive tape. To connect the two webs, the holding roller holding the prepared web is pressed against the deflecting roller for the running web. A knife cuts off the connected webs that are still pulled off behind the roller for the web that is running off. The disadvantage here is that the connection of the two webs has a residual flag. This leads to difficulties in the further course of the web. In addition, the adhesive connection is only subjected to a relatively short pressure. There is a risk of web breaks.

Der Erfindung liegt die Aufgabe zugrunde, die bekannte Vor­richtung so auszubilden, daß die Splicung der beiden Bahnen ohne Restfahne erfolgt und daß eine erhöhte Splicesicherheit gewährleistet wird.The invention has for its object to design the known device so that the splicing of the two webs takes place without a residual lug and that increased security against splices is ensured.

Die Erfindung löst diese Aufgabe mit den kennzeichnenden Merkmalen des Patentanspruches 1.The invention solves this problem with the characterizing features of claim 1.

Dadurch, daß die Splicung der beiden Bahnen ohne Restfahne erfolgt, wird eine erhöhte Splicesicherheit für den weiteren Ablauf der Bahn durch die gesamte Wellpappenanlage gewähr­leistet.The fact that the two webs are spliced without a residual flag ensures increased splice security for the further course of the web through the entire corrugated cardboard system.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements of the invention result from the subclaims.

Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. In der Zeichnung zeigen:

Zwischen den Wangen 10, von denen die vordere als abgenommen anzusehen ist, befindet sich am rechten Endteil eine Umlenkwalze 11 und eine Umlenkwalze 12 für die ablaufende Bahn 13. Eine An­preß- und Umlenkwalze 14, wird von der ablaufenden Bahn 13 umschlungen. Von dieser Umlenkwalze 14 läuft die Bahn 13 dann weiter zu einer waagrecht geführten, gegen eine vor­eingestellte Kraft bewegliche Speicherwalze 15, die zwischen der vollausgezogenen Walzenstellung bis zur strichpunktiert angegebenen Walzenstellung eine Bahnschleife 16 bildet. Von der Speicherwalze 15 läuft die Bahn 13 waagrecht zu einer Ablaufwalze 17 am linken Ende der Wangen 10. Von dort ge­langt die Bahn 13 weiter zu einer nicht dargestellten Vor­richtung der gesamten Wellpappenanlage.The stand 8 of the unwind stand 2 resting on the floor 7 continues upwards into a stand part 9 which carries horizontal cheeks 10 of the splicing device 1. Between the cheeks 10, of which the front is to be regarded as removed, there is a deflecting roller 11 and a deflecting roller 12 for the running web 13 on the right end part. A pressing and deflecting roller 14 is wrapped by the running web 13. From this deflection roller 14, the web 13 then continues to a horizontally guided storage roller 15 which is movable against a preset force and which forms a web loop 16 between the fully extended roller position and the roller position indicated by dot-dash lines. The web 13 runs horizontally from the storage roller 15 to a discharge roller 17 at the left end of the cheeks 10. From there, the web 13 continues to a device (not shown) of the entire corrugated cardboard system.

Die Anpreß- und Umlenkwalze 14 ist an einer hin und her schwenkbaren Wippe 20 drehbar gelagert. Die Wippe 20 ist um die ortsfeste Mittelachse 21 schwenkbar. Am gegenüberliegen­ den Wippenende ist eine weitere Anpreß- und Umlenkwalze 22 drehbar angeordnet. Die Anpreß- und Umlenkwalzen 14 und 22 sind wechselweise zueinander verschiebbar.The pressure and deflection roller 14 is rotatably mounted on a rocker 20 which can be pivoted back and forth. The rocker 20 can be pivoted about the fixed central axis 21. At the opposite a further pressure and deflection roller 22 is rotatably arranged at the rocker end. The pressure and deflection rollers 14 and 22 are mutually displaceable.

Unterhalb der Anpreß- und Umlenkwalze 14 ist eine Haltewalze 25 drehbar und verschiebbar in einer Führungsbahn 26 ange­ordnet. Die Haltewalze 25 hält in Arbeitsstellung A unter­halb der Anpreß- und Umlenkwalze 14 den Anfang 27 der vorbe­reiteten Bahn 28 fest, die von der Papierrolle 6 auf dem Armpaar 4 abgezogen ist.A holding roller 25 is rotatably and displaceably arranged in a guide track 26 below the pressure roller and deflection roller 14. The holding roller 25 holds in the working position A below the pressure and deflection roller 14, the beginning 27 of the prepared web 28, which is pulled off the paper roll 6 on the pair of arms 4.

Hierzu kann die Haltewalze 25 mit einer Haftklebeschicht 29 und/oder mit Saugdüsen versehen sein.For this purpose, the holding roller 25 can be provided with a pressure-sensitive adhesive layer 29 and / or with suction nozzles.

In der Ausgangsstellung B nimmt die Haltewalze 25 die in Fig. 1 strichpunktierte Stellung am linken Ende der Wangen 10 ein. In diese Ausgangsstellung B gelangt die Haltewalze 25 über die nach abwärts gekrümmte Führungsbahn 26. In der Ausgangsstellung B ist die Haltewalze 25 in ihrer Drehlage festgelegt.In the initial position B, the holding roller 25 assumes the position shown in broken lines in FIG. 1 at the left end of the cheeks 10. The holding roller 25 reaches this starting position B via the downwardly curved guide track 26. In the starting position B, the holding roller 25 is fixed in its rotational position.

Das Ende 30 der vorbereiteten Papierbahn 28 wird zunächst über die Umlenkwalze 31 geführt und dann über die Haltewalze 25 gelegt.The end 30 of the prepared paper web 28 is first passed over the deflection roller 31 and then placed over the holding roller 25.

Ein balkenförmiger Messerträger 35 ist in Ausgangsstellung B neben der Haltewalze 25 angeordnet. Dieser Messerträger 35 ist gleichfalls über die Führungsbahn 26 in diese Ausgangs­stellung B verschiebbar. In dieser Ausgangsstellung B kann der Messerträger 35 an die Haltewalze 25 angepreßt werden. In dieser Stellung kann der Messerträger 35 dann mit der Haltewalze 25 verklinkt sein.A bar-shaped knife carrier 35 is arranged in the starting position B next to the holding roller 25. This knife carrier 35 can likewise be moved into this starting position B via the guideway 26. In this starting position B, the knife carrier 35 can be pressed against the holding roller 25. In this position, the knife carrier 35 can then be latched to the holding roller 25.

Die Anpreßfläche 36 an der einen Seite 37 des Messerträgers 35 ist entsprechend der Oberfläche der Haltewalze 25 ge­wölbt. Die Anpreßfläche 36 kann einen entsprechenden elasti­ schen Belag aufweisen.The contact surface 36 on one side 37 of the knife carrier 35 is curved in accordance with the surface of the holding roller 25. The contact surface 36 can have a corresponding elastic have a covering.

Das Bahnende 30 wird mit einer Verbindungsschicht, vorzugs­weise einem beidseitig klebenden Band 40, vorzugsweise 5 cm breit, oder einem anderen Klebemittel, z.B. Hot Melt, aufge­sprüht oder als Raupenauftrag versehen. Hinter der Klebe­schicht wird das Ende 30 mittels einem Messer 41 manuell bzw. automatisch unter Zuhilfenahme einer Schneidleiste 42 definiert beschnitten.The web end 30 is covered with a bonding layer, preferably a double-sided adhesive tape 40, preferably 5 cm wide, or another adhesive, e.g. Hot melt, sprayed on or applied as a caterpillar application. Behind the adhesive layer, the end 30 is trimmed manually or automatically using a knife 41 with the aid of a cutting bar 42.

Die Haltewalze 25 mit dem verklinkten Messerträger 35 mit Bahn 28 wird nun in die Arbeitsstellung A nach Fig. 1 verschoben. Dabei wird, wie ersichtlich, die Bahn 28 um die Umlenkwalze 32 geführt. Der Messerträger 35 wird in eine horizontale Lage überführt. Die Haltewalze 25 wird dabei in einer solchen Stellung gehalten, daß das Bahnende 30 die Walze 25 halbkreisförmig umschließt.The holding roller 25 with the latched knife carrier 35 with the web 28 is now moved into the working position A according to FIG. 1. As can be seen, the web 28 is guided around the deflection roller 32. The knife carrier 35 is brought into a horizontal position. The holding roller 25 is held in such a position that the web end 30 encloses the roller 25 in a semicircular shape.

Der Messerträger 35 besitzt an der der Seite 37 gegenüber­liegenden Seite wiederum eine gewölbte Anpreßfläche 43, ent­sprechend ausgebildet wie die Anpreßfläche 36. Außerdem be­sitzt er eine ebene, vorzugsweise waagrechte Oberseite 44, über die die ablaufende Bahn 13 verläuft.The knife carrier 35 in turn has a curved contact surface 43 on the side opposite the side 37, correspondingly designed as the contact surface 36. In addition, it has a flat, preferably horizontal upper side 44 over which the running web 13 runs.

Weiterhin besitzt der Messerträger 35 zwei sich über die ganze Bahnbreite erstreckende Zackenmesser 45, 46. Diese sind wechselweise aus der eingezogenen Stellung in die Wirk­stellung ausschiebbar, wozu eine nicht dargestellte Messer­antriebsvorrichtung dient. Die Messer 45, 46 verlaufen schräg zur Bahn 13. Das ausgefahrene linke Messer 45 er­streckt sich dabei, wie aus Fig. 3 ersichtlich, in den freien Zwickelraum 47 zwischen den aneinandergepreßten Wal­zen 14 und 25. Dadurch kann die ablaufende Bahn 13 in ge­ringster Entfernung von der linienförmigen Berührung der Walzen 14, 25 abgeschnitten werden. Diese Entfernung ent­spricht etwa der Breite der Verbindungsschicht, z.B. dem Klebeband 40.Furthermore, the knife carrier 35 has two serrated knives 45, 46 which extend over the entire width of the web. These can alternately be pushed out of the retracted position into the active position, for which purpose a knife drive device, not shown, is used. The knives 45, 46 run obliquely to the web 13. The extended left knife 45 extends, as can be seen in FIG. 3, into the free gusset space 47 between the rollers 14 and 25 pressed against one another the linear contact of the rollers 14, 25 are cut off. This distance corresponds approximately to the width of the connection layer, for example that Adhesive tape 40.

Der Messerträger 35 ist über die sich nach rechts (Fig. 1) fortsetzende Führungsbahn 26 auch in eine rechte Ausgangs­stellung B′ überführbar. In dieser arbeitet er mit einer zweiten Haltewalze 39 zusammen, um den Anfang 30′ einer vorbereiteten Papierrolle 6 in dem rechten Armpaar 3, wie beschrieben, zu klemmen (Fig. 2).The knife carrier 35 is on the right (Fig. 1) continuing guideway 26 also in a right starting position B 'can be transferred. In this he works with a second holding roller 39 to clamp the beginning 30 'of a prepared paper roll 6 in the right pair of arms 3, as described (Fig. 2).

Wie aus Fig. 1 ersichtlich, sind neben den Anpreß- und Um­lenkwalzen 14 und 22 höhenbewegliche Anpreßbalken 50, 51 an­geordnet. Diese besitzen an ihrer Unterseite einen Reibbelag 52. Die Anpreßbalken 50, 51 werden wechselweise gegen die Oberseite 44 des Messerträgers 35 gepreßt und halten dadurch die zwischen der Unterseite des Anpreßbalkens 50, 51 und der Oberseite 44 des Messerbalkens 35 hindurchlaufende ablau­fende Papierbahn 13 fest.As can be seen from FIG. 1, in addition to the pressure and deflection rollers 14 and 22, height-adjustable pressure bars 50, 51 are arranged. These have a friction lining 52 on their underside. The pressure bars 50, 51 are pressed alternately against the top 44 of the knife carrier 35 and thereby hold the running paper web 13 running between the bottom of the pressure bar 50, 51 and the top 44 of the knife bar 35.

Eine geänderte Ausführung der verschiebbaren Haltewalze 39 und Messerträger 35 ist in den Figuren 5, 6 und 7 darge­stellt. Die Führungsbahn 26 besteht hierbei aus einem waag­rechten Mittelteil 60, das von einer im Querschnitt U-förmi­gen Schiene 61 gebildet ist. Die Endteile 62 der Führungs­bahn 26 werden jeweils von einer geraden, im Querschnitt wiederum U-förmigen Schiene 63 gebildet. In der in Fig. 5 dargestellten Stellung fluchten die Schienen 61 und 62 mit­einander. Die Länge des Endteiles 62 ist so bemessen, daß es den Wagen 64 mit in den Schienen 61, 62 laufenden Rollen 65 für die Haltewalze 39 (entsprechend der vorbereiteten Pa­pierrolle 6 in rechter Stellung, Fig. 2) und Wagen 66 mit Rollen 67 für Messerträger 35 mit Abstand voneinander auf­nehmen kann.A modified version of the displaceable holding roller 39 and knife carrier 35 is shown in FIGS. 5, 6 and 7. The guideway 26 here consists of a horizontal central part 60 which is formed by a rail 61 with a U-shaped cross section. The end parts 62 of the guideway 26 are each formed by a straight rail 63, again U-shaped in cross section. In the position shown in FIG. 5, the rails 61 and 62 are aligned with one another. The length of the end part 62 is such that it is the carriage 64 with rollers 65 running in the rails 61, 62 for the holding roller 39 (corresponding to the prepared paper roll 6 in the right position, FIG. 2) and carriage 66 with rollers 67 for knife carriers 35 can accommodate at a distance from each other.

Das Endteil 62 ist mit einem Schwenkansatz 68 fest verbun­den, der um eine Schwenkachse 69 hin und her schwenkbar ge­lagert ist. Dadurch ist das Endteil 62 aus der in Fig. 5 dargestellten Aufnahmestellung in die abgesenkte Ausgangs­stellung B′ nach Fig. 6 zur Aufnahme des Endteiles 30 der vorbereiteten Papierbahn 28 geeignet.The end part 62 is fixedly connected to a pivot attachment 68, which is pivotably mounted to and fro about a pivot axis 69. As a result, the end part 62 is from that in FIG. 5 6 shown in the lowered starting position B 'of FIG. 6 suitable for receiving the end portion 30 of the prepared paper web 28.

Dieses Absenken des Endteils 62 kann über eine Betätigungs­vorrichtung 70, z. B. bestehend aus einem Gestänge 71, ma­nuell oder selbsttätig gesteuert erfolgen.This lowering of the end part 62 can be done via an actuating device 70, e.g. B. consisting of a linkage 71, manually or automatically controlled.

Wie aus Fig. 6 ersichtlich, werden Haltewalze 39 und Messer­träger 35 zunächst im Abstand voneinander gehalten in die abgekippte Lage zur Aufnahme des Endes 30′ der vorbereiteten Papierrolle 6 auf den rechten Armen 3 (Fig. 2) überführt. Nach Einfädeln des Endes 30′ der vorbereiteten Papierbahn 28 wird der Messerträger 35 in die Anpreßlage überführt, wobei die rechte Anpreßfläche 38 mit der Walze 39 zusammenwirkt. Walze 39 und Messerträger 35 können in dieser Lage verklinkt werden. Das Messer 41 beschneidet dann in Verbindung mit der Messerleiste 42 (vergl. Fig. 7), die am Wagen 64 der Halte­walze 25 positionierbar angeordnet sein kann, das Ende 30′ der vorbereiteten Papierbahn 28.As can be seen from Fig. 6, the holding roller 39 and knife carrier 35 are initially held at a distance from each other in the tilted position for receiving the end 30 'of the prepared paper roll 6 on the right arms 3 (Fig. 2) transferred. After threading the end 30 'of the prepared paper web 28, the knife carrier 35 is transferred to the pressure position, the right pressure surface 38 cooperating with the roller 39. Roller 39 and knife carrier 35 can be latched in this position. The knife 41 then cuts in conjunction with the knife bar 42 (see FIG. 7), which can be positioned on the carriage 64 of the holding roller 25, the end 30 'of the prepared paper web 28th

Hierauf wird zur gegebenen Zeit das Endteil 62 in die Stel­lung nach Fig. 5 zurückgekippt. Die Walze 39 mit Messerträ­ger 35 mit Papierbahn 28 werden in Arbeitsstellung A unter die Walze 22 überführt.The end part 62 is then tilted back into the position shown in FIG. 5 at the appropriate time. The roller 39 with knife carrier 35 with paper web 28 are transferred into the working position A under the roller 22.

Die Splicevorrichtung 1 arbeitet wie folgt:The splicing device 1 works as follows:

Es wird angenommen, daß wie in Fig. 1 gezeigt, die Papier­rolle 5 in der angedeuteten Pfeilrichtung abgewickelt wird und daß die ablaufende Papierbahn 13 über die Umlenkwalzen 11, 12, die Anpreß- und Umlenkwalze 14, sowie über die Speicherwalze 15 der Auslaufwalze 17 zuläuft.It is assumed that, as shown in Fig. 1, the paper roll 5 is unwound in the direction indicated by the arrow and that the outgoing paper web 13 runs over the deflection rollers 11, 12, the pressure and deflection roller 14, and also over the storage roller 15 of the outlet roller 17 .

Eine neue Papierrolle 6 ist auf das Armpaar 4 links der Mit­telebene XX angebracht. Das abgezogene Endteil 30 dieser Pa­ pierrolle 6 nimmt die strichpunktierte Lage ein. Es verläuft über die untere Umlenkwalze 31 zur in Ausgangsstellung B be­findlichen Haltewalze 25 (strichpunktiert dargestellt). Durch Anpressen des Messerträger 35 an die Walze 25 wird das Ende 30 festgelegt. Ein Messer 41 mit Schneidleiste 42 be­schneidet dieses Endteil 30. Dabei steht das Bahnende etwa 5 cm frei über den Messerträger 35 vor. Es wird nun ein ebenso breites beidseitig klebendes Band 40 oder ein andere Klebe­mittel auf dieses Bahnende aufgebracht. Hierauf fährt die Haltewalze 25 samt verklinktem Messerträger 35 mit Papieran­fang 30 in die Arbeitsstellung A unter die Anpreß- und Um­lenkwalze 14, welche nach links zur Mittelebene XX versetzt angeordnet ist. Diese Walze 14 wird von der ablaufenden Bahn 13 umschlungen. Die nun in Arbeitsstellung A befindliche Haltewalze 25 hält das Ende der vorbereiteten neuen Bahn 28 an der Oberseite etwa in der Mitte fest. Die Walzen 14 und 25 sind noch geringfügig voneinander beabstandet.A new paper roll 6 is attached to the pair of arms 4 on the left of the middle plane XX. The peeled end part 30 of this Pa pierrolle 6 takes the dot-dash position. It runs over the lower deflection roller 31 to the holding roller 25 located in the starting position B (shown in broken lines). The end 30 is fixed by pressing the knife carrier 35 against the roller 25. A knife 41 with a cutting bar 42 cuts this end part 30. The end of the web projects about 5 cm freely above the knife carrier 35. An equally wide, double-sided adhesive tape 40 or another adhesive is now applied to this end of the web. Thereupon, the holding roller 25 together with the latched knife carrier 35 with paper start 30 moves into the working position A under the pressure and deflection roller 14, which is arranged offset to the left to the central plane XX. This roller 14 is wrapped in the running web 13. The holding roller 25, which is now in working position A, holds the end of the prepared new web 28 at the top approximately in the middle. The rollers 14 and 25 are still slightly spaced apart.

Geht die Bahn 13 der Papierrolle 5 zuende, wird ggf. durch ein Auslösesignal der Splicevorgang automatisch eingeleitet. Um den Anfang 30 der mit einem Klebeband 40 versehenen vor­bereiteten neuen Bahn 28 unter Vermeidung einer Restfahne an die ablaufende Bahn 13 anzukleben, ist zunächst die ablau­fende Bahn 13 zum Stillstand zu bringen. Hierzu wird der rechts in Fig. 1 neben der Walze 14 befindliche Anpreßbalken 50 in der angegebenen Pfeilrichtung (Fig. 3) nach abwärts mit seiner Reibfläche 52 gegen die ablaufende Bahn 13 und die Oberseite 44 des darunter befindlichen Messerträger 35 gepreßt. Dadurch wird die ablaufende Bahn 13 auf v = 0 abge­bremst. Anstelle eines Reibbelages 52 könnte auch eine Vaku­umsaugfläche im Anpreßbalken 50 verwendet werden.If the web 13 of the paper roll 5 comes to an end, the splicing process may be initiated automatically by a trigger signal. In order to adhere the beginning 30 of the prepared new web 28 provided with an adhesive tape 40 to the running web 13 while avoiding a residual flag, the running web 13 must first be brought to a standstill. For this purpose, the pressure bar 50 located on the right in FIG. 1 next to the roller 14 is pressed downward in the indicated arrow direction (FIG. 3) with its friction surface 52 against the running web 13 and the upper side 44 of the knife carrier 35 located underneath. As a result, the running web 13 is braked to v = 0. Instead of a friction lining 52, a vacuum suction surface in the pressure beam 50 could also be used.

Hierauf wird die auf der Wippe 20 drehbar sitzende Anpreß- und Umlenkwalze 14 durch geringfügiges Schwenken der Wippe 20 in der angegebenen Pfeilrichtung gegen die Walze 25 ge­preßt und die beiden Bahnen 30 und l3 werden im Preßspalt verklebt. Die Anpreß- und Umlenkwalze 14 ist vorzugsweise mit einem elastischen Belag versehen.Then the pressure and deflection roller 14, which is rotatably seated on the rocker 20, is pressed against the roller 25 by slightly pivoting the rocker 20 in the direction indicated by the arrow, and the two webs 30 and 13 are in the press nip glued. The pressure and deflection roller 14 is preferably provided with an elastic covering.

Die ablaufende Bahn 13 wird nun durch das Messer 45 des Mes­serträgers 35 im Zwickel 47 nahe der Anpreßstelle der beiden Walzen 14 und 25 abgeschnitten. Die Länge des freien Endes der ablaufenden Papierbahn 13 entspricht etwa der Breite des Klebebandes 40. Vorzugsweise ist die Länge bzw. Breite etwa 50 mm. Da auf die ablaufende Bahn 13 über die sich verklei­nernde Speicherschleife 16 immer noch ein Bahnzug ausgeübt wird, wird nach Lösung der Verklinkung der Haltewalze 25 und Messerträger 35 sowie Wegfahren desselben von der Walze 25 die vorbereitete, neue Bahn 28 über die drehende Walze 25 hinweggezogen. Die in Anpreßstellung befindliche Walze 14 sorgt dabei für ein festes Aneinanderdrücken der zu verkle­benden Bahnteile.The running web 13 is now cut off by the knife 45 of the knife carrier 35 in the gusset 47 near the contact point of the two rollers 14 and 25. The length of the free end of the running paper web 13 corresponds approximately to the width of the adhesive tape 40. The length or width is preferably approximately 50 mm. Since a web tension is still exerted on the running web 13 via the shrinking storage loop 16, after the latching of the holding roller 25 and knife carrier 35 has been released and the roller 25 has moved away from the roller 25, the prepared new web 28 is pulled over the rotating roller 25. The roller 14 in the pressing position ensures that the web parts to be glued are firmly pressed together.

Vorzugsweise wird die andere, nicht in Arbeitsstellung be­findliche etwas hoch geschwenkte Umlenk- und Anpreßwalze 22 auf der Wippe 20 in Richtung der Walze 14 in der angegebenen Pfeilrichtung verschoben, bis sie in Anpreßstellung zur Walze 14 gelangt (vergl. Fig. 3). Hierdurch wird eine Nach­preßung der zwischen diesen beiden Walzen 22 und 14 durch­laufenden Verklebung der Bahn 13 und Bahn 28 erreicht. Somit wird eine sichere Verbindung der fahnenlosen verklebten nachgepreßten Verbindung von ablaufender Bahn 13 mit vorbe­reiteter neuer Bahn 28 erreicht (vergl. Fig. 4).Preferably, the other, not in the working position, slightly swiveled deflection and pressure roller 22 is moved on the rocker 20 in the direction of the roller 14 in the direction indicated by the arrow until it reaches the roller 14 in the pressure position (see FIG. 3). As a result, re-pressing of the web 13 and web 28 between these two rollers 22 and 14 is achieved. A secure connection of the flameless, glued, re-pressed connection of the running web 13 with the prepared new web 28 is thus achieved (cf. FIG. 4).

Die Walze 25 (Fig. 1 und 2) wird nun in die Ausgangsstellung B am linken Ende der Wangen 10 verschoben. Die Bahn 13 der Papierrolle 5 auf dem linken Tragarmpaar 4 läuft dann ent­gegen dem Uhrzeigersinn in der in Fig. 2 gezeigten Weise über die Umlenkwalze 31, die Umlenkwalze 32 zur zurückver­schobenen Umlenk- und Anpreßwalze 22, hochgeschwenkten Um­lenk- und Anpreßwalze 14, Speicherwalze 15 und Auslaufwalze 17 ab.The roller 25 (FIGS. 1 and 2) is now moved into the starting position B at the left end of the cheeks 10. The web 13 of the paper roll 5 on the left pair of support arms 4 then runs counter-clockwise in the manner shown in FIG Outlet roller 17 from.

Der Messerträger 35 wird in Fig. 1 nach rechts in die abge­senkte und beabstandete Lage zu einer weiteren Haftwalze 39 verschoben. Es wird nun auf die rechten Haltearme 3 eine neue vorbereitete Papierrolle 6 aufgebracht. Deren Ende 30′ wird über die Umlenkwalze 11 zur Haltewalze 39 geführt, wie beschrieben beschnitten und durch den Messerträger 35 ge­klemmt.The knife carrier 35 is shifted to the right in FIG. 1 into the lowered and spaced-apart position to a further adhesive roller 39. A new prepared paper roll 6 is now applied to the right holding arms 3. The end 30 'is guided over the deflecting roller 11 to the holding roller 39, trimmed as described and clamped by the knife carrier 35.

Für einen neue Splicevorgang wird Haltewalze 39 mit ver­klinktem Messerträger 35 in die Arbeitsstellung A über­führt, wobei die Haltewalze 39 unter die Umlenk- und An­preßwalze 22 zu liegen kommt. Über dem Messerträger 35 be­findet sich nun der Anpreßbalken 51.For a new splicing process, the holding roller 39 is brought into the working position A with the knife carrier 35 locked, the holding roller 39 coming to rest under the deflection and pressure roller 22. The pressure bar 51 is now located above the knife carrier 35.

Zur gegebenen Zeit wiederholt sich erneut der bereits be­schriebene Splicevorgang. Hierauf fährt der Messerträger 35 wieder in die in Fig. 1 gezeigte Stellung am linken Ende der Wangen 10.The splicing process already described is repeated again at the appropriate time. The knife carrier 35 then moves back to the position shown in FIG. 1 at the left end of the cheeks 10.

Wie aus Fig. 8 ersichtlich, können die Anpreß- und Umlenk­walzen 14, 22 auch mit den Anpreßbalken 50, 51 jeweils zu einer Einheit 80, 81 zusammengefaßt sein. Entweder sind beide Einheiten 80, 81 zueinander, in die Anpreßstellung verschiebbar oder die eine Einheite 80 ist ortsfest, während die andere verdrehbar und an die andere anpreßbar ist. Zu­sätzlich sind die Anpreß- und Umlenkwalzen 14, 22 sowie die Anpreßbalken 50, 51 absenkbar und abhebbar angeordnet.As can be seen from FIG. 8, the pressure and deflection rollers 14, 22 can also be combined with the pressure bars 50, 51 to form a unit 80, 81, respectively. Either both units 80, 81 can be moved relative to one another, into the pressing position, or one unit 80 is stationary, while the other can be rotated and pressed against the other. In addition, the pressure and deflection rollers 14, 22 and the pressure bars 50, 51 can be lowered and raised.
