Abstract

The method involves rolling a material-web (9) using a material-roller. A section-edge is produced by cutting another material-web (11) along cutting-directions (38, 40), where the cutting-directions include an angle lying between specific degrees. The two material-webs are connected in an area of the section-edge to an endless material-web (21). The material-webs are arranged in an overlap free manner with respect to each other. The material web (11) is rolled by another material roller. An independent claim is also included for a splice device comprising a rolling device.

Description

Die Erfindung betrifft ein Verfahren zum Splicen von Material-Bahnen, insbesondere von Papier-Bahnen zur Herstellung einer Wellpappe-Bahn in einer Wellpappe-Anlage, sowie eine zugehörige Splice-Vorrichtung.The invention relates to a method for splicing material webs, in particular paper webs for producing a corrugated web in a corrugated board system, as well as an associated splicing device.

Bekannte Splice-Vorrichtungen verbinden eine zu Ende gehende erste Material-Bahn mit einer neuen zweiten Material-Bahn, so dass eine endlose Material-Bahn entsteht. Dieser Vorgang wird in der Fachsprache als Splicen und eine entsprechende Vorrichtung als Splice-Vorrichtung bezeichnet.Known splicing devices connect a finished first web of material to a new second web of material to form an endless web of material. This process is referred to in the jargon as Splicen and a corresponding device as Splice device.

Ein bekanntes Verfahren zum Splicen von Material-Bahnen sieht vor, die zu verbindenden Material-Bahnen teilweise übereinander anzuordnen, wobei zwischen den Material-Bahnen ein doppelseitig klebendes Klebe-Band angebracht ist. Dieses Verfahren hat den Nachteil, dass es im Verbindungs-Bereich der Material-Bahnen zu einer Material-Verdoppelung kommt, die bei der Weiterverarbeitung der erzeugten endlosen Material-Bahn zu erheblichen Problemen führt. Ein weiteres bekanntes Verfahren zum Splicen von Material-Bahnen sieht vor, die zu verbindenden Material-Bahnen Kante an Kante auf einem einseitig klebenden Klebe-Band anzuordnen. Bei diesem Verfahren wird zwar eine Material-Verdoppelung im Verbindungs-Bereich vermieden, jedoch weist die erzeugte endlose Material-Bahn im Verbindungs-Bereich keine ausreichende Steifigkeit auf, da der Verbindungs-Bereich als eine Art Scharnier wirkt. Die mangelnde Steifigkeit führt ebenfalls zu erheblichen Problemen bei der Weiterverarbeitung der endlosen Material-Bahn in der Wellpappe-Anlage.A known method for splicing material webs provides partially to arrange the material webs to be connected one above the other, wherein between the material webs a double-sided adhesive tape is attached. This method has the disadvantage that it comes in the connection region of the material webs to a doubling of material, which leads to the processing of the endless material web produced further significant problems. Another known method for splicing material webs provides to arrange the material webs to be joined edge to edge on a single-sided adhesive tape. While this method avoids material doubling in the bonding area, the endless web of material produced in the bonding area does not have sufficient rigidity because the bonding area acts as a hinge. The lack of stiffness also leads to significant problems in the further processing of the endless material web in the corrugated board plant.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Splice-Vorrichtung zum Splicen von Material-Bahnen zu schaffen, die ein einfaches und für eine Weiterverarbeitung der Material-Bahnen unproblematisches Verbinden der Material-Bahnen ermöglichen.The invention has for its object to provide a method and a splicing device for splicing material webs, which is a simple and allow for further processing of the material webs unproblematic connection of the material webs.

Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche 1 und 9 gelöst. Der Kern der Erfindung besteht darin, dass vor dem Verbinden der Material-Bahnen zu einer endlosen Material-Bahn Schnitt-Kanten an den Material-Bahnen erzeugt werden, wobei sich die Schnitt-Kanten im Wesentlichen lückenlos zu der endlosen Material-Bahn ergänzen. Die Schnitt-Kanten werden durch Schneiden der Material-Bahnen mindestens entlang einer ersten Schneid-Richtung und entlang einer zweiten Schneid-Richtung erzeugt, wobei die Schneid-Richtungen einen Winkel α derart einschließen, dass 0° < α < 180° gilt. Beim Verbinden der Material-Bahnen werden diese im Wesentlichen überlappungsfrei und lückenlos zueinander angeordnet, so dass eine Material-Verdoppelung und aufgrund der profilierten sowie komplementär zueinander ausgebildeten Schnitt-Kanten eine Scharnier-Wirkung vermieden wird. Zum Erzeugen der Schnitt-Kanten weist die Splice-Vorrichtung mindestens eine Schneide- und Verbinde-Einrichtung mit entlang den Schneid-Richtungen verlaufenden Schneid-Abschnitten auf.This object is solved by the features of independent claims 1 and 9. The essence of the invention is that, prior to joining the webs of material to an endless web of material, cut edges are produced on the webs of material, the cut edges complementing one another substantially continuously to the endless web of material. The cut edges are produced by cutting the material webs at least along a first cutting direction and along a second cutting direction, the cutting directions enclosing an angle α such that 0 ° <α <180 °. When connecting the material webs, these are arranged substantially without overlapping and gaplessly with respect to one another, so that a material doubling and, due to the profiled and complementarily formed cut edges, a hinge effect is avoided. To create the cut edges, the splicing device has at least one cutting and joining device with cutting sections running along the cutting directions.

Nach den Verbindungs-Einheiten 24, 25 wird die als endlose Material-Bahn 21 bezeichnete erste Material-Bahn 9 mittels der ersten Umlenk-Walze 54 um 180° umgelenkt und zu der zweiten Umlenk-Walze 55 geführt, wo die endlose Material-Bahn 21 erneut um 180° umgelenkt wird. Der Schlitten 56 befindet sich zunächst - wie in Fig. 1 gezeigt - in der zweiten Schlitten-End-Position. Nach der zweiten Umlenk-Walze 55 wird die endlose Material-Bahn 21 zu der dritten Umlenk-Walze 58 geführt, wo die endlose Material-Bahn 21 um 180° umgelenkt und zu der vierten Umlenk-Walze 60 zurückgeführt wird. Dadurch, dass die vierte Umlenk-Walze 60 einen im Vergleich zu der zweiten Umlenk-Walze 55 kleineren Walzen-Durchmesser aufweist, kann die endlose Material-Bahn 21 ohne sich selbst zu berühren nochmals um 180° umgelenkt und zum Auslauf 59 geführt werden, wo die endlose Material-Bahn 21 die Splice-Vorrichtung 1 zur Herstellung von Wellpappe verlässt.The operation of the splicing device 1 will be described below. The first material web 9 is unrolled from the first material roll 10 and passed over the feed roller 18 by the Anpress rollers 43 of the connecting units 24, 25. As shown in FIG. 1, the adhesive roller 29 of the first preparation unit 22 is adjacent to the first cross cutter 30 of the first preparation unit 22. The table unit 26 and the glue roller 29 of the second preparation unit 23 are initially in the position shown in Fig. 2. After the connecting units 24, 25, the first material web 9 designated as endless material web 21 is deflected by the first deflecting roller 54 by 180 ° and guided to the second deflecting roller 55, where the endless material web 21 again deflected by 180 °. The carriage 56 is initially - as shown in Fig. 1 - in the second carriage-end position. After the second deflection roller 55, the endless material web 21 is guided to the third deflection roller 58, where the endless material web 21 is deflected by 180 ° and returned to the fourth deflection roller 60. Due to the fact that the fourth deflection roller 60 has a smaller roller diameter than the second deflection roller 55, the endless material web 21 can be redirected again by 180 ° without touching itself and guided to the outlet 59, where the endless material web 21 leaves the splicing device 1 for the production of corrugated cardboard.

Aufgrund des stetigen Abrollens der ersten Material-Bahn 9 geht die erste Material-Rolle 10 nach einer bestimmten Zeit zu Ende, so dass die zweite Material-Bahn 11 mit der ersten Material-Bahn 9 verbunden werden muss.Due to the continuous rolling of the first material web 9, the first material roll 10 ends after a certain time, so that the second material web 11 has to be connected to the first material web 9.

Hierzu wird die zweite Material-Bahn 11 zunächst manuell oder automatisch über die Zuführ-Walze 18 der Klebe-Walze 29 der zweiten Vorbereitungs-Einheit 23 zugeführt. Durch Drehen der Klebe-Walze 29 wird die zweite Material-Bahn 11 dem ersten Querschneider 30 zugeführt, wobei die zweite Material-Bahn 11 zwischen der Querschneider-Auflage 32 und dem ersten Messer-Balken 33 angeordnet wird. Zum Halten der zweiten Material-Bahn 11 in dieser Position wird die Tisch-Einheit 26 in der ersten Verlagerungs-Richtung 28 verlagert, so dass einer der Anpress-Puffer 52 gegen die zweite Material-Bahn 11 anliegt und diese gegen die Klebe-Walze 29 presst.For this purpose, the second material web 11 is first supplied manually or automatically via the feed roller 18 of the adhesive roller 29 of the second preparation unit 23. By rotating the adhesive roller 29, the second material web 11 is fed to the first cross cutter 30, the second material web 11 being arranged between the cross cutter support 32 and the first knife beam 33. For holding the second material web 11 in this position, the table unit 26 is displaced in the first displacement direction 28, so that one of the Anpress-buffer 52 abuts against the second material web 11 and this against the adhesive roller 29th pressed.

Zum Erzeugen einer ersten Schnitt-Kante 61 wird der erste Messer-Balken 33 in die zweite Verlagerungs-Richtung 35 verlagert, so dass die zweite Material-Bahn 11 vollständig durchtrennt wird. Beim Durchtrennen der zweiten Material-Bahn 11 taucht der erste Messer-Balken 33 in die Auflage-Nut 36 der Querschneider-Auflage 32 ein. Nach dem Durchtrennen der zweiten Material-Bahn 11 wird der erste Messer-Balken 33 entgegen die zweite Verlagerungs-Richtung 35 in die Ausgangsposition zurückverlagert.To produce a first cutting edge 61, the first knife bar 33 is displaced in the second displacement direction 35, so that the second material web 11 is completely severed. When severing the second material web 11, the first knife bar 33 dives into the support groove 36 of the cross cutter support 32. After severing the second material web 11, the first knife bar 33 is displaced back against the second displacement direction 35 to the starting position.

Die erste Schnitt-Kante 61 weist aufgrund der ersten und zweiten Schneid-Abschnitte 37, 39 des ersten Messer-Balkens 33 erste Teil-Schnitt-Kanten 62, die entlang der ersten Schneid-Richtung 38 verlaufen, und zweite Teil-Schnitt-Kanten 63, die entlang der zweiten Schneid-Richtung 40 verlaufen, auf. Die Teil-Schnitt-Kanten 62, 63 schließen entsprechend den Schneid-Richtungen 37, 39 einen Winkel α von 90° ein. Die erste Schnitt-Kante 61 ist aufgrund der in unterschiedlichen Schneid-Richtungen 38, 40 verlaufenden Teil-Schnitt-Kanten 62, 63 profiliert ausgebildet und weist erste Schnitt-Kanten-Vorsprünge 64 und erste Schnitt-Kanten-Vertiefungen 65 auf, die ein Positiv-Profil der ersten Schnitt-Kante 61 bilden. Die ersten Schnitt-Kanten-Vorsprünge 64 und die ersten Schnitt-Kanten-Vertiefungen 65 sind rechteckförmig oder quadratisch ausgebildet.The first cutting edge 61 has, due to the first and second cutting portions 37, 39 of the first knife beam 33, first part-cutting edges 62 extending along the first cutting direction 38 and second part-cutting edges 63 extending along the second cutting direction 40. The part-cut edges 62, 63 close in accordance with the cutting directions 37, 39 an angle α of 90 °. The first cut edge 61 is formed profiled due to the split-cut edges 62, 63 extending in different cutting directions 38, 40, and has first cut edge projections 64 and first cut edge depressions 65 that are positive Profile of the first cut edge 61 form. The first Cut-edge protrusions 64 and the first cut-edge recesses 65 are formed rectangular or square.

Nach dem Erzeugen der ersten Schnitt-Kante 61 wird mittels der Zuführ-Einheit das einseitig klebende Klebe-Band 41 zugeführt und zwischen der zweiten Material-Bahn 11 und der Querschneider-Auflage 32 im Bereich der ersten Schnitt-Kanten-Vorsprünge 64 und der ersten Schnitt-Kanten-Vertiefungen 65 angeordnet, wobei mittels der Vakuum-Pumpe die zweite Material-Bahn 11 beim Zuführen angehoben wird. Das Klebe-Band 41 definiert einen Verbindungs-Bereich 66 und überdeckt die ersten Schnitt-Kanten-Vorsprünge 64 sowie die ersten Schnitt-Kanten-Vertiefungen 65 vollständig.After the production of the first cut edge 61, the single-sided adhesive tape 41 is fed by means of the feed unit and between the second material web 11 and the cross cutter support 32 in the region of the first cut edge projections 64 and the first Cut edges recesses 65 are arranged, wherein by means of the vacuum pump, the second material web 11 is raised during feeding. Adhesive tape 41 defines a bonding area 66 and completely covers the first cut-edge protrusions 64 and the first cut-edge depressions 65.

Nach dem Anbringen des Klebe-Bandes 41 gibt die Tisch-Einheit 26 die zweite Material-Bahn 11 frei. Durch Drehen der Klebe-Walze 29 wird die zweite Material-Bahn 11 aus dem ersten Querschneider 30 entfernt, wobei das Drehen der Klebe-Walze 29 so lange erfolgt, bis das Klebe-Band 41 in einem der Tisch-Einheit 26 zugewandten Bereich auf der Klebe-Walze 29 zu liegen kommt. Anschließend wird die zweite Material-Bahn 11 wieder mittels der Tisch-Einheit 26 gegen die Klebe-Walze 29 gepresst und die Tisch-Einheit 26 zusammen mit der Klebe-Walze 29 und der zweiten Material-Bahn 11 entgegen die erste Verlagerungs-Richtung 28 in der Führung 27 zu der zweiten Verbindungs-Einheit 25 verlagert. Dieser Zustand ist in Fig. 3 gezeigt.After attaching the adhesive tape 41, the table unit 26 releases the second material web 11. By rotating the adhesive roller 29, the second material web 11 is removed from the first cross cutter 30, wherein the rotation of the adhesive roller 29 takes place until the adhesive tape 41 in a table unit 26 facing region on the Adhesive roller 29 comes to rest. Subsequently, the second material web 11 is again pressed by means of the table unit 26 against the adhesive roller 29 and the table unit 26 together with the adhesive roller 29 and the second material web 11 against the first displacement direction 28 in FIG the guide 27 is displaced to the second connection unit 25. This condition is shown in FIG.

Aufgrund der bekannten Länge der ersten Material-Bahn 9 erkennt die Splice-Vorrichtung 1, wann die erste Material-Rolle 10 zu Ende geht. Bevor dies eintritt, wird die vorbereitete zweite Material-Bahn 11 mit der ersten Material-Bahn 9 verbunden. Hierzu wird zunächst das Abrollen der ersten Material-Bahn 9 abgebremst und gestoppt, wobei durch das Verlagern des Schlittens 56 von der zweiten Schlitten-End-Position in die erste Schlitten-End-Position die mittels der Umlenk-Walzen 54, 55, 58, 60 von der Material-Bahn 21 gebildeten Schleifen aufgelöst werden und die Material-Bahn 21 weiterhin die Splice-Vorrichtung 1verlässt.Due to the known length of the first material web 9, the splicing device 1 recognizes when the first material roll 10 comes to an end. Before this occurs, the prepared second material web 11 is connected to the first material web 9. For this purpose, the first of the unwinding braked and stopped by moving the carriage 56 from the second carriage end position to the first carriage end position by means of the deflection rollers 54, 55, 58, 60 of the material web 21 formed loops are dissolved and the material web 21 continues to leave the splicing device 1.

Zum Verbinden der Material-Bahnen 9, 11 wird zunächst die erste Material-Bahn 9 mittels des zweiten Querschneiders 42 vollständig durchtrennt, so dass eine zweite Schnitt-Kante 67 erzeugt wird. Zum Erzeugen der zweiten Schnitt-Kante 67 wird der zweite Messer-Balken 45 in der dritten Verlagerungs-Richtung 47 verlagert, wobei der zweite Messer-Balken 45 in die zugehörige Tisch-Nut 50 des Tisches 48 eintaucht. Nach dem Durchtrennen der ersten Material-Bahn 9 wird der zweite Messer-Balken 45 entgegen die dritte Verlagerungs-Richtung 47 in die Ausgangsposition zurückverlagert.For joining the material webs 9, 11, first the first material web 9 is completely severed by means of the second cross cutter 42, so that a second cut edge 67 is produced. To generate the second cut edge 67, the second knife bar 45 is displaced in the third displacement direction 47, the second knife bar 45 dipping into the associated table groove 50 of the table 48. After severing the first material web 9, the second knife bar 45 is displaced back against the third displacement direction 47 to the starting position.

Die zweite Schnitt-Kante 67 weist entsprechend den ersten Schneid-Abschnitten 37 des zweiten Messer-Balkens 45 erste Teil-Schnitt-Kanten 62, die entlang der ersten Schneid-Richtung 38 verlaufen, und entsprechend den zweiten Schneid-Abschnitten 39 des zweiten Messer-Balkens 45 zweite Teil-Schnitt-Kanten 63, die entlang der zweiten Schneid-Richtung 40 verlaufen, auf. Die zweite Schnitt-Kante 67 ist aufgrund der unterschiedlichen Schneid-Richtungen 38, 40 ebenfalls profiliert ausgebildet und weist zweite Schnitt-Kanten-Vorsprünge 68 und zweite Schnitt-Kanten-Vertiefungen 69 auf, die ein Negativ-Profil bilden. Die zweiten Schnitt-Kanten-Vorsprünge 68 und die zweiten Schnitt-Kanten-Vertiefungen 69 sind ebenfalls rechteckförmig oder quadratisch ausgebildet.The second cutting edge 67 has, corresponding to the first cutting portions 37 of the second knife bar 45, first part-cutting edges 62 which run along the first cutting direction 38 and corresponding to the second cutting portions 39 of the second knife edge. Beams 45 second part-cut edges 63 which extend along the second cutting direction 40 on. The second cutting edge 67 is also formed profiled due to the different cutting directions 38, 40 and has second cut-edge projections 68 and second cut-edge depressions 69, which form a negative profile. The second cut-edge projections 68 and the second cut-edge depressions 69 are also rectangular or square.

Die erste Schnitt-Kante 61 und die zweite Schnitt-Kante 67 sind komplementär zueinander ausgebildet und ergänzen sich im Wesentlichen überlappungsfrei und lückenlos zu der endlosen Material-Bahn 21. Das Positiv-Profil der ersten Schnitt-Kante 61 ergänzt das Negativ-Profil der zweiten Schnitt-Kante 67 derart, dass beim Verbinden der Material-Bahnen 9, 11 die ersten Schnitt-Kanten-Vorsprünge 64 in die zweiten Schnitt-Kanten-Vertiefungen 69 und die zweiten Schnitt-Kanten-Vorsprünge 68 in die ersten Schnitt-Kanten-Vertiefungen 65 greifen. Die Schnitt-Kanten 61, 67 greifen mit den Schnitt-Kanten-Vorsprüngen 64, 68 und den Schnitt-Kanten-Vertiefungen 65, 69 somit fingerartig ineinander.The first cut edge 61 and the second cut edge 67 are formed complementary to each other and complement each other substantially without overlap and gap to the endless material web 21. The positive profile of the first cut edge 61 complements the negative profile of the second Cutting edge 67 such that when joining the material webs 9, 11, the first cut edge projections 64 in the second cut edge recesses 69 and the second cut edge projections 68 in the first cut edge recesses 65 grab. The cut edges 61, 67 thus interlock with the cut edge projections 64, 68 and the cut edge recesses 65, 69 in a finger-like manner.

Zum Verbinden der Material-Bahnen 9, 11 gibt die Tisch-Einheit 26 die zweite Material-Bahn 11 mit dem Klebe-Band 41 frei und die Material-Bahnen 9, 11 werden mittels der Klebe-Walze 29 und der Anpress-Walze 43 derart durch den Verbindungs-Spalt 44 geführt, dass die erste Material-Bahn 9 auf dem von der zweiten Material-Bahn 11 unbedeckten Teil des Klebe-Bandes 41 zu liegen kommt und im Wesentlichen überlappungsfrei und lückenlos mit der zweiten Material-Bahn 11 zu der endlosen Material-Bahn 21 verbunden wird. Die erzeugte endlose Material-Bahn 21 weist somit den durch das Klebe-Band 41 definierten Verbindungs-Bereich 66 auf, in dem die Material-Bahnen 9, 11 entlang der Transport-Richtung 53 in der beschriebenen Weise ineinander greifen. Der Verbindungs-Bereich 66 weist entlang der Transport-Richtung 53 eine Länge Lv zwischen 1 cm und 10 cm, insbesondere zwischen 2 cm und 8 cm, und insbesondere zwischen 3 cm und 6 cm auf. Die ersten Teil-Schnitt-Kanten 62 verlaufen im Wesentlichen senkrecht zu der Transport-Richtung 53 und die zweiten Teil-Schnitt-Kanten 63 verlaufen im Wesentlichen parallel zu der Transport-Richtung 53. Alternativ können die Teil-Schnitt-Kanten 62, 63 auch unter einem beliebigen Winkel zu der Transport-Richtung 53 angestellt sein, so dass der Verbindungs-Bereich 66 schräg zu der Transport-Richtung 53 verläuft und unter einem Winkel β von ungleich 90° zu der Transport-Richtung 53 angestellt ist.To connect the material webs 9, 11, the table unit 26 releases the second material web 11 with the adhesive tape 41 and the material webs 9, 11 are so by means of the adhesive roller 29 and the pressure roller 43 guided through the connection gap 44, that the first material web 9 comes to lie on the uncovered from the second material web 11 part of the adhesive tape 41 and substantially overlap-free and gapless with the second material web 11 to the endless Material web 21 is connected. The produced endless material web 21 thus has the connection region 66 defined by the adhesive band 41, in which the material webs 9, 11 engage in one another along the transport direction 53 in the manner described. The connection region 66 has along the transport direction 53 a length L v between 1 cm and 10 cm, in particular between 2 cm and 8 cm, and in particular between 3 cm and 6 cm. The first part-cut edges 62 are substantially perpendicular to the transport direction 53 and the second part-cut edges 63 are substantially parallel to the transport direction 53. Alternatively, the part-cut edges 62, 63 may also at any angle to the transport direction 53 employed be so that the connecting portion 66 extends obliquely to the transport direction 53 and is set at an angle β of not equal to 90 ° to the transport direction 53.

Nach dem Verbinden der Material-Bahnen 9, 11 wird die zweite Material-Bahn 11 von der zweiten Material-Rolle 12 abgerollt. Während des Abrollens der zweiten Material-Bahn 11 wird der Schlitten 56 zur Bildung von Schleifen der Material-Bahn 21 von der ersten Schlitten-End-Position in die zweite Schlitten-End-Position verlagert. Außerdem wird während des Abrollens der zweiten Material-Bahn 11 die Klebe-Walze 29 der zweiten Vorbereitungs-Einheit 23 in der ersten Verlagerungs-Richtung 28 verlagert und im Bereich des zugehörigen ersten Querschneiders 30 angeordnet. Ferner wird eine neue erste Material-Rolle 10 in der ersten Abroll-Einrichtung 7 angeordnet und die Tisch-Einheit 26 entgegen die erste Verlagerungs-Richtung 28 zu der ersten Vorbereitungs-Einheit 22 verlagert, so dass die neue erste Material-Bahn 9 zum Verbinden mit der zweiten Material-Bahn 11 in bereits beschriebener Weise vorbereitet werden kann. Das Schneiden und Verbinden der Material-Bahnen 9, 11 wiederholt sich nun.After joining the material webs 9, 11, the second material web 11 is unrolled from the second material roll 12. During the unwinding of the second material web 11, the carriage 56 is displaced from the first carriage end position to the second carriage end position to form loops of the material web 21. In addition, during the rolling of the second material web 11, the adhesive roller 29 of the second preparation unit 23 is displaced in the first displacement direction 28 and arranged in the region of the associated first transverse cutter 30. Furthermore, a new first material roll 10 is placed in the first unrolling device 7 and the table unit 26 is displaced against the first relocation direction 28 to the first preparation unit 22, so that the new first material web 9 for joining can be prepared with the second material web 11 in the manner already described. The cutting and joining of the material webs 9, 11 is now repeated.

Nachfolgend wird unter Bezugnahme auf die Fig. 6 ein zweites Ausführungsbeispiel der Erfindung beschrieben. Konstruktiv identische Teile erhalten dieselben Bezugszeichen wie bei dem ersten Ausführungsbeispiel, auf dessen Beschreibung hiermit verwiesen wird. Konstruktiv unterschiedliche, jedoch funktionell gleichartige Teile erhalten dieselben Bezugszeichen mit einem nachgestellten a. Der wesentliche Unterschied gegenüber dem ersten Ausführungsbeispiel besteht in der Ausgestaltung der Schnitt-Kanten 61 a, 67a und der Schnitt-Kanten-Vorsprünge 64a, 68a sowie der Schnitt-Kanten-Vertiefungen 65a, 69a. Die Schnitt-Kanten 61a, 67a sind zickzackförmig und in Folge dessen die Schnitt-Kanten-Vorsprünge 64a, 68a sowie die Schnitt-Kanten-Vertiefungen 65a, 69a dreieckförmig ausgebildet. Die Schneid-Richtungen 38a, 40a schließen einen Winkel α von kleiner als 90° ein. Die Schneid-Richtungen 38a, 40a sind relativ zu der Transport-Richtung 53 unter einem Winkel angestellt, wobei dieser Winkel die Hälfte von α ist. Alternativ können die Schneid-Richtungen 38a, 40a auch mit unterschiedlichen Winkeln relativ zu der Transport-Richtung 53 angestellt sein. Der Verbindungs-Bereich 66a ist im Wesentlichen mit einem Winkel von β ungleich 90° relativ zu der Transport-Richtung 53 angestellt. Alternativ kann der Verbindungs-Bereich 66a auch unter einem Winkel β von ungleich 90° relativ zu der Transport-Richtung 53 angestellt sein. Die Teil-Schnitt-Kanten 62a, 63a weisen jeweils die gleiche Länge auf und werden durch entsprechend verlaufende Schneid-Abschnitte 37a, 39a, die nicht näher dargestellt sind, erzeugt.Hereinafter, a second embodiment of the invention will be described with reference to FIG. Structurally identical parts are given the same reference numerals as in the first embodiment, to the description of which reference is hereby made. Structurally different but functionally similar parts receive the same reference numerals with a following a. The main difference compared to the first embodiment is the configuration of the cut edges 61 a, 67 a and the cut edge projections 64 a, 68 a and the cut edge recesses 65 a, 69 a. The cut edges 61a, 67a are zigzag-shaped and as a result the cut edge projections 64a, 68a and the cut-edge recesses 65a, 69a are triangular in shape. The cutting directions 38a, 40a include an angle α of less than 90 °. The cutting directions 38a, 40a are made at an angle relative to the transport direction 53, this angle being half of α. Alternatively, the cutting directions 38a, 40a may also be set at different angles relative to the transporting direction 53. The connection region 66a is set substantially at an angle of β not equal to 90 ° relative to the transport direction 53. Alternatively, the connection region 66a may also be set at an angle β which is not equal to 90 ° relative to the transport direction 53. The part-cut edges 62a, 63a each have the same length and are generated by correspondingly extending cutting portions 37a, 39a, which are not shown in detail.

Nachfolgend wird unter Bezugnahme auf die Fig. 7 ein drittes Ausführungsbeispiel der Erfindung beschrieben. Konstruktiv identische Teile erhalten dieselben Bezugszeichen wie bei dem ersten Ausführungsbeispiel, auf dessen Beschreibung hiermit verwiesen wird. Konstruktiv unterschiedliche, jedoch funktionell gleichartige Teile erhalten dieselben Bezugszeichen mit einem nachgestellten b. Der wesentliche Unterschied gegenüber den vorangegangenen Ausführungsbeispielen besteht in der Ausgestaltung der Schnitt-Kanten 61b, 67b und der Schnitt-Kanten-Vorsprünge 64b, 68b sowie der Schnitt-Kanten-Vertiefungen 65b, 69b. Die Schnitt-Kanten 61b, 67b und die Schnitt-Kanten-Vorsprünge 64b, 68b sowie die Schnitt-Kanten-Vertiefungen 65b, 69b sind wellenförmig ausgebildet, wobei das Erzeugen der Schnitt-Kanten 61b, 67b - mathematisch betrachtet - durch Schneiden der Material-Bahnen 9, 11 entlang von unendlich vielen Schneid-Richtungen erfolgt. Beispielhaft sind in Fig. 7 zwei Schneid-Richtungen 38b, 40b eingezeichnet, die - mathematisch betrachtet - Tangenten der Schnitt-Kanten 61b, 67b in einzelnen Punkten sind. Die einzelnen Punkte stellen die Teil-Schnitt-Kanten 62b, 63b dar, die in ihrer Gesamtheit die differenzierbaren Schnitt-Kanten 61b, 67b bilden. Die in Fig. 7 eingezeichneten Schneid-Richtungen 38b, 40b schließen ungefähr einen Winkel α von 45° ein. Die erste Schneid-Richtung 38b verläuft relativ zu der Transport-Richtung 53 im Wesentlichen senkrecht. Der Verbindungs-Bereich 66b ist relativ zu der Transport-Richtung 53 unter einem Winkel β von ungefähr 90° angestellt. Alternativ kann der Verbindungs-Bereich 66b auch unter einem Winkel β von ungleich 90° zu der Transport-Richtung 53 angestellt sein. Die Teil-Schnitt-Kanten 62b, 63b korrespondieren zu entsprechend verlaufenden Schneid-Abschnitten 37b, 39b, die nicht näher dargestellt sind.Hereinafter, a third embodiment of the invention will be described with reference to FIG. Structurally identical parts are given the same reference numerals as in the first embodiment, to the description of which reference is hereby made. Structurally different, but functionally similar parts receive the same reference numerals with a trailing b. The essential difference with respect to the preceding embodiments is the configuration of the cut edges 61b, 67b and the cut edge projections 64b, 68b and the cut edge depressions 65b, 69b. The cutting edges 61b, 67b and the cut-edge projections 64b, 68b and the cut-edge depressions 65b, 69b are wave-shaped, wherein the generation of the cut edges 61b, 67b - mathematically considered - by cutting the material Tracks 9, 11 takes place along an infinite number of cutting directions. By way of example, two cutting directions 38b, 40b are shown in FIG. 7, which - in mathematical terms - are tangents the cut edges 61b, 67b are in single points. The individual dots represent the partial-cut edges 62b, 63b, which in their entirety constitute the differentiable cut edges 61b, 67b. The cutting directions 38b, 40b shown in FIG. 7 include approximately an angle α of 45 °. The first cutting direction 38b is substantially perpendicular relative to the transport direction 53. The connection region 66b is set at an angle β of approximately 90 ° relative to the transport direction 53. Alternatively, the connection region 66b may also be set at an angle β which is not equal to 90 ° to the transport direction 53. The part-cut edges 62b, 63b correspond to correspondingly extending cutting portions 37b, 39b, which are not shown in detail.

Prinzipiell können die Schnitt-Kanten beliebig profiliert geformt sein, solange sie komplementär zueinander ausgebildet sind und sich die Material-Bahnen 9, 11 im Wesentlichen überlappungsfrei und lückenlos zu der endlosen Material-Bahn 21 ergänzen. Die mindestens zwei Schneid-Richtungen schließen einen Winkel α derart ein, dass 0° < α < 180° gilt. Für den Winkel α der Schneid-Richtungen gilt insbesondere 30° ≤ α ≤ 150°, insbesondere 45° ≤ α ≤ 135°, und insbesondere 60° ≤ α ≤ 120°. Dadurch, dass die Material-Bahnen 9, 11 im Wesentlichen überlappungsfrei und lückenlos im Bereich der Schnitt-Kanten ineinander greifen, wird einerseits eine Material-Verdoppelung und andererseits eine Scharnier-Wirkung im Verbindungs-Bereich verhindert.In principle, the cut edges can be formed profiled in any desired way, as long as they are complementary to each other and the material webs 9, 11 complement each other substantially without overlap and without gaps to the endless material web 21. The at least two cutting directions include an angle α such that 0 ° <α <180 °. For the angle α of the cutting directions, in particular 30 ° ≦ α ≦ 150 °, in particular 45 ° ≦ α ≦ 135 °, and in particular 60 ° ≦ α ≦ 120 °. Due to the fact that the material webs 9, 11 intermesh substantially without overlap and gap in the area of the cut edges, material doubling on the one hand and hinging action in the connecting region on the other hand is prevented.
