Vorrichtung zur Herstellung von ungefalteten Abschnitten aus einer Bahn aus Papier, Zellstoff, Faservliesen oder dgl.Device for the production of unfolded sections from a web of paper, cellulose, Nonwovens or the like.
Zusatz zu:P 22 49 767.2Addition to: P 22 49 767.2
Die Erfindung betrifft eine Verbesserung einer Vorrichtung zur Herstellung von ungefalteten Abschnitten aus einer Bahn aus Papier, Zellstoff, Faservliesen oder dgl. nach Patent 2 24? 767.The invention relates to an improvement of an apparatus for producing unfolded sections from a web Paper, cellulose, nonwovens or the like according to Patent 2 24? 767.
Gegenstand des Hauptpatentes ist ein Verfahren und eine Vorrichtung zur Herstellung von ungefalteten Abschnitten aus einer Bahn aus Papier, Zellstoff, Faservliesen oder dgl·, bei der die Falten an den beiden Randpartien des Stapels unmittelbar nach dem Falten abgeschnitten werden. Dazu dient nach dem Hauptpatent eine Vorrichtung, bei der einer Zickzack-Faltmaschine zwei parallel zueinander angeordnete Bandmesser rachgeschaltet sind, deren paralleler Abstand kleiner ist als die Breite des Stapels.The main patent relates to a method and a device for the production of unfolded sections from a web of paper, cellulose, nonwovens or the like which the folds on the two edge parts of the stack are cut off immediately after folding. This is used according to the main patent a device in which a zigzag folding machine is switched up with two band knives arranged parallel to one another whose parallel spacing is smaller than the width of the stack.

Der Gegenstand des Hauptpatentes hat sich gut bewährt. Handelt es sich bei der Bahn, aus der die ungefalteten Abschnitte geschnitten werden sollen, um sehr weiches biegsames Material, so kann es jedoch vorkommen, daß beim Abschneiden die gefalteten Enden den Bandmessern ganz oder teilweise ausweichen, so daß die Falten unvollkommen abgeschnitten werden oder statt der geraden, gekrümmte Seitenkanten entstehen.The subject matter of the main patent has proven itself well. Acts the web from which the unfolded sections are to be cut is a very soft, pliable material, however, it can happen that the folded ends give way completely or partially to the band knives when they are cut, so that the folds are cut off imperfectly or instead of straight, curved side edges arise.
Gemäß der Zusatzerfindung kann diesem Mißstand dadurch abgeholfen werden, daß bei der Vorrichtung nach dem Hauptpatent in Bewegungsrichtung des Stapels vor den Bandmessern beiderseits des Stapels Walzen mit Längsrillen angeordnet sind, die im gleichen Drehsinn rotieren, wie die entsprechenden Walzen der Zickzack—Faltmaschine, d.h. jeweils in solchem Drehsinn, daß die den Stapel zugewandten Seiten der Walzen sich in der gleichen Richtung bewegen wie der Stapel. Die Längsrillen der Walzexi sind zweckmäßig sägezahnförmig, wobei die steileren Flanken der Zähne in Drehrichtung nach vorne liegen. Durch diese Walzen werden die abzuschneidenden Falten auf ihre ganze Länge erfaßt und gegen die Bandmesser geschoben, so daß sie dem Schnitt nicht ausweichen können und ein glatter gerader Schnitt sichergestellt ist.According to the additional invention, this deficiency can be remedied that in the device according to the main patent in the direction of movement of the stack in front of the band knives on both sides of the stack rollers with longitudinal grooves are arranged, which rotate in the same direction of rotation as the corresponding rollers of the zigzag folding machine, i.e. each in such direction of rotation, that the sides of the rollers facing the stack move in the same direction as the stack. The longitudinal grooves of the Walzexi are appropriately sawtooth-shaped, with the steeper ones The flanks of the teeth lie forward in the direction of rotation. By means of these rollers, the folds to be cut off are completely covered Recorded length and pushed against the bandknife so that they cannot avoid the cut and a smooth straighter Cut is ensured.
Um die Drehgeschwindigkeit der Walzen dem jeweils zu verarbeitenden Material anwtpassen zu können, werden die beiden Walzen zweckmäßig durch einen eigenen Antrieb, d.h. durch einen vom Antrieb der Zickzack-Faltmaschine unabhängigen Antrieb mit einstellbarer Drehzahl angetrieben. Der Antrieb kann jedoch auch von der Hauptwelle der Zickzack-Faltmaschine,gegebenenfalls unter Zwischenschaltung eines Wechselgetriebes, erfolgen. Zweckmäßig werden die beiden Walzen mit einer solchen Drehzahl angetrieben, daß die Umfangsgeschwindigkeit der Walzen größer ist als die Vorrückgeschwindigkeit des Stapels, wodurch erreicht wird, daß unmittelbar vor den Bandmessern die Lagen der zickzackfömig gefalteten Bahn dichter aufeinanderliegen alsIn order to be able to adapt the rotational speed of the rollers to the material to be processed, the two rollers are expediently driven by their own drive, ie by a drive with an adjustable speed that is independent of the drive of the zigzag folding machine. However, the drive can also come from the main shaft of the zigzag folding machine, if necessary with the interposition of a change gear. The two rollers are expediently driven at such a speed that the circumferential speed of the rollers is greater than the advance speed of the stack, whereby it is achieved that the layers of the zigzag-folded web lie closer to one another than directly in front of the band knives

in de* Abschnitt zwischen den Faltzylindern und den Walzen, Zur Vereinfachung der Anordnung und um ein symmetrisches Arbeiten der Maschine sicherzustellen, können die beiden Walzen durch einen gemeinsamen Antriebssynchron angetrieben werden. Zusätzlich kann noch eine in Bewegungsrichtung des Stapels bewegbare Platte vorgesehen sein, an der die vorrückende Stirnseite des Stapels anliegt, so daß das weiche Material \on der Stirnseite her gestützt wird und dadurch verhindert wird, daß sich zwischen den Bandsägen das Material durchbiegt oder schräg stellt.in de * section between the folding cylinders and the rollers, Zur Simplification of the arrangement and to ensure a symmetrical operation of the machine, the two rollers can by one common drive are driven synchronously. Additionally can a movable plate in the direction of movement of the stack can also be provided, on which the advancing end face of the stack so that the soft material is supported on the front side and thereby prevents the material from sagging or tilting between the band saws.
Ein Ausführungäoeispiel einer Vorrichtung gemäß der Erfindung ist in der Figur dargestellt.An embodiment of a device according to the invention is shown in the figure.
Die Figur zeigt die Vorrichtung im Grundriß. Wie bei der Vorrichtung nach dem Hauptpatent wird die zu faltende Bahn 2 den Falzzylindern 5 zugeführt, die um ihre vertikalen Drehachsen rotieren und die nicht dargestellte Falze besitzen, so daß die Bahn abwechselnd von dem einen und dem anderen Zylinder 5 erfaßt und nach rechts bzw. links gezogen wird und,wie dargestellt, diesen Teil der Vorrichtung als zickzackförmig gefalteter Stapel 8a verläßt. Im Anschluß an die Falzzylinder 5 sind zu beiden Seiten dies Stapels 8a die Bandmesser 6a und 6b so angeordnet, daß die vertikalen Randpartien des Stapels 8a abgeschnitten werden. Die abgeschnittenen Enden 7 jeder einzelnen Falte fallen ab und aus der Vorrichtung tritt ein Stapel 8b aus, der aus einzelnen ungefalteten Abschnitten besteht. Gemäß der Erfindung sind vor den Bandmessern 6a, 6b zwei Walzen 10a, 10b angeordnet, die durch eine nicht gezeichnete Antriebsvorrichtung in solchem Drehsinn angetrieben werden, daß sich die dem Stapel zugewandten Seiten in der gleichen Richtung bewegen, wie der Stapel, wie dies durch die in die Walzen 10a, 10b eingezeichneten Pfeile angedeutet ist. Die Drehrichtun-g dieser Walzen stimmt somit, wie aus den in die Walzen 5 eingezeichneten Pfeile ersichtlich, jeweils mit der Drehrichtung des auf der gleichen Seite liegenden Zylinders der Faltvorrichtung überein. Wie dargestellt, sind die Walzen 10a, 10b mit Längsrillen versehen,The figure shows the device in plan. As in the device according to the main patent, the web 2 to be folded is fed to the folding cylinders 5, which rotate about their vertical axes of rotation and have the folds (not shown), so that the web is alternately grasped by one and the other cylinder 5 and to the right or to the right. is pulled to the left and, as shown, leaves this part of the device as a zigzag folded stack 8a. Following the folding cylinder 5, the band knives 6a and 6b are arranged on both sides of this stack 8a in such a way that the vertical edge portions of the stack 8a are cut off. The cut ends 7 of each individual fold fall off and a stack 8b emerges from the device and consists of individual unfolded sections. According to the invention, two rollers 10a, 10b are arranged in front of the band knives 6a, 6b, which are driven by a drive device (not shown) in such a direction of rotation that the sides facing the stack move in the same direction as the stack, as shown by the in the rollers 10a, 10b drawn arrows is indicated. The direction of rotation of these rollers thus corresponds, as can be seen from the arrows drawn in the rollers 5, with the direction of rotation of the cylinder of the folding device lying on the same side. As shown, the rollers 10a, 10b are provided with longitudinal grooves,

die sägezahnförmig sind, wobei die steilen Flanken 11 der Zähne in Drehrichtung vorangehen. Durch diese steilen Planken der Zähne der Walzen, deren Länge mindestens gleich der Höhe des Stapels ist, werden die Falten auf ihre ganze Länge erfaßt und gegen die Bandmesser 6a, 6b geschoben. Dabei werden die Walzen 10a, 10b zweckmäßig mit einer Geschwindigkeit angetrieben, die etwas größer ist als die Vorrückgeschwindigkeit des Stapels 8a, wodurch erreicht wird, daß die einzelnen Lagen der Zickzackförmig gefalteten Bahn vor den Bandmessern fest aufeinanderliegen, so daß auch sehr weiches Material sich nicht durchbiegen oder dem Sägeschnitt ausweichen kann. Auf diese Weise ist sichergestellt, dazwischen den Sägemessern ein Stapel 8b heraustritt, der aus einzelnen ungefalteten Abschnitten mit sauber beschnittenen Rändern besteht. Dieser Stapel 8b liegt mit seiner Stirnseite an einer Platte 12 an, die in Bewegungsrichtung des Stapels bewegbar ist und mit dem Vorrücken des Stapels zurückweicht. Wird ein Teil des Stapels 8b zur weiteren Verarbeitung und Verpackung entnommen, so rückt die Platte 12 wieder bis zur neuen Stirnseite des Stapels vor und stützt diese beim weiteren Vorrücken ab.which are sawtooth-shaped, with the steep flanks 11 of the teeth go ahead in the direction of rotation. Through these steep planks of the teeth of the rollers, the length of which is at least equal to the height of the Stack is, the folds are grasped over their entire length and pushed against the band knives 6a, 6b. Thereby the rollers 10a, 10b expediently driven at a speed that is slightly greater than the advance speed of the stack 8a, whereby it is achieved that the individual layers of the zigzag folded web lie tightly on top of each other in front of the band knives, so that even very soft material does not bend or can avoid the saw cut. That way is ensures that a stack 8b emerges between the saw blades, which consists of individual unfolded sections with cleanly trimmed edges. This stack 8b rests with its end face on a plate 12, which extends in the direction of movement of the stack is movable and recedes as the stack advances. Part of the stack 8b becomes another Processing and packaging removed, the plate 12 advances again to the new end face of the stack and provides support this off as you advance.
