Description

Die Erfindung betrifft eine Materialbahnschneideinrichtung zum Zerschneiden einer Materialbahn, insbesondere einer Kunststofffolie, in eine Vielzahl von Streifen mit einer Zuführung zum kontinuierlichen Transport der Materialbahn in eine Bahnlängsrichtung, und mit mehreren quer zur Bahnlängsrichtung in einer Querrichtung in einem Abstand zueinander angeordneten Schneidmessern zum Bilden der Streifen.The invention relates to a material web cutting device for cutting a material web, in particular a plastic film, in a plurality of strips with a feed for the continuous transport of the web in a web longitudinal direction, and with a plurality of transverse to the web direction in a transverse direction in a spaced cutting blades for forming the strips ,

Bei den bekannten Materialbahnschneideinrichtungen werden in einem Rüstvorgang die Schneidmesser gemäß der gewünschten Breite der zu bildenden Streifen montiert, wobei die Gesamtsumme der Breite der einzelnen Streifen zweckmäßigerweise auf die Breite der zugeführten Materialbahn abgestimmt ist.In the known material web cutting devices, the cutting knives are mounted according to the desired width of the strip to be formed in a setup process, wherein the total sum of the width of the individual strips is suitably adapted to the width of the supplied material web.

Da die Breite der zugeführten Materialbahn innerhalb von Produktionsschwankungen variieren kann, erfolgt in der Praxis an einer Seite oder auch an beiden Seiten ein Besäumungsschnitt, an dem überstehende äußere Ränder abgeschnitten werden, die dann als Ausschuss anfallen.Since the width of the supplied material web can vary within production variations, in practice on one side or on both sides a Besäumungsschnitt be cut off at the protruding outer edges, which then incurred as a committee.

Um beispielsweise acht Streifen zu bilden, sind dann neun Schneidmesser vorgesehen, wobei die beiden äußeren Schneidmesser zur Entfernung des überstehenden Randes vorgesehen sind.For example, to form eight strips, then nine cutting blades are provided, the two outer cutting blades are provided to remove the protruding edge.

Eine gattungsgemäße Materialbahnschneideinrichtung zum Zerschneiden einer Materialbahn, insbesondere einer elastischen Folie, in eine Vielzahl von Streifen ist aus der DE 10 2004 035 649 B4 bekannt, wobei die detaillierte Ausgestaltung der Materialbahnschneideinrichtung nicht beschrieben ist.A generic material web cutting device for cutting a material web, in particular an elastic film, in a plurality of strips is from the DE 10 2004 035 649 B4 known, wherein the detailed configuration of the material web cutting device is not described.

Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zugrunde, bei dem Bilden von Streifen aus einer Materialbahn mit einfachen Mitteln eine Effizienzsteigerung zu erreichen.Against this background, the object of the present invention is to achieve an increase in efficiency in the formation of strips from a material web with simple means.

Gegenstand der Erfindung und Lösung der Aufgabe sind eine Materialbahnschneideinrichtung gemäß Patentanspruch 1 sowie ein Verfahren zur Bildung einer Vielzahl von Streifen aus einer Materialbahn gemäß Patentanspruch 11.The object of the invention and solution of the problem are a material web cutting device according to claim 1 and a method for forming a plurality of strips of a material web according to claim 11.

Ausgehend von einer gattungsgemäßen Materialbahnschneideinrichtung ist demnach erfindungsgemäß vorgesehen, dass die Materialbahnschneideinrichtung zumindest einen an eine Steuerung angeschlossenen Lagesensor aufweist, der zur Bestimmung einer Position eines Randes der Materialbahn eingerichtet ist, wobei eine Messerverstellanordnung ebenfalls an die Steuerung angeschlossen ist und wobei zumindest ein Teil der Schneidmesser in Querrichtung durch die Messerverstellanordnung verschiebbar ist.Proceeding from a generic material web cutting device, it is accordingly provided according to the invention that the material web cutting device has at least one position sensor connected to a control, which is set up to determine a position of an edge of the material web, wherein a knife adjustment arrangement is likewise connected to the control and at least one part of the cutting blade in the transverse direction by the Messerverstellanordnung is displaced.

Durch den zumindest einen an die Steuerung angeschlossenen Lagesensor kann auf eine variierende Breite der zugeführten Materialbahn in Querrichtung reagiert werden, wobei dann die Schneidmesser in Querrichtung durch die Messerverstellanordnung entsprechend verschoben werden können.By the at least one position sensor connected to the control can be reacted to a varying width of the supplied material web in the transverse direction, in which case the cutting blades can be moved in the transverse direction by the Messerverstellanordnung accordingly.

Zweckmäßigerweise ist die Messerverstellanordnung dazu eingerichtet, einen äquidistanten Abstand zwischen den in Querrichtung aufeinanderfolgenden Schneidmessern einzustellen.Conveniently, the Messerverstellanordnung is adapted to set an equidistant distance between the successive cross-cutting blades.

Auf einen Beschnitt der Materialbahn an einem äußeren Rand wird erfindungsgemäß verzichtet. Vielmehr können die Schneidmesser so positioniert werden, dass auch die an den beiden Rändern der Materialbahn gebildeten Streifen trotz der Schwankungen der Breite der zugeführten Materialbahn innerhalb vorgegebener Toleranzen liegen.On a trimming of the material web at an outer edge is omitted according to the invention. Rather, the cutting blades can be positioned so that the strips formed at the two edges of the material web despite the variations in the width of the supplied material web are within predetermined tolerances.

Es ist somit möglich, mit einer vorgegebenen Anzahl von n Schneidmessern n+1 Streifen zu bilden.It is thus possible to form n + 1 strips with a predetermined number of n cutting blades.

Wenn dann die Breite der Materialbahn von einem Sollwert B um eine Differenz von ΔB abweicht, kann diese Maßabweichung gleichmäßig auf die n+1 Streifen verteilt werden. Für jeden Streifen ergibt sich dann von einer Soll-Breite b eine Abweichung Δb = ΔB/(n+1).If then the width of the material web deviates from a desired value B by a difference of ΔB, this dimensional deviation can be distributed evenly over the n + 1 stripes. For each strip, a deviation Δb = ΔB / (n + 1) then results from a desired width b.

Da die Maßabweichung der gesamten Materialbahn in der Querrichtung ΔB gleichmäßig auf sämtliche Streifen verteilt wird, können üblicherweise vorgegebene Toleranzen für die Breite der einzelnen Streifen eingehalten werden, so dass keine weiteren Korrekturmaßnahmen notwendig sind.Since the dimensional deviation of the entire material web in the transverse direction .DELTA.B is uniformly distributed over all the strips, usually predetermined tolerances for the width of the individual strips can be maintained, so that no further corrective measures are necessary.

Gegenüber einer aus dem Stand der Technik bekannten Materialbahnschneideinrichtung werden also weniger Schneidmesser benötigt, weil kein Beschnitt abgetrennt werden muss. Es ergeben sich dadurch hinsichtlich der Schneidmesser geringere Anlagen- und Wartungskosten.Compared to a material web cutting device known from the prior art so less cutting blades are needed because no trimming must be separated. This results in respect of the cutting blade lower investment and maintenance costs.

Hinzu kommt, dass durch den Wegfall eines Beschnitts am Rande der Material-bahn eine bisher notwendige Entsorgung des abgeschnittenen Materials entfällt, wodurch sich eine erhebliche Effizienzsteigerung unter Reduzierung der Kosten und des Materialeinsatzes ergibt.In addition, the elimination of a cut at the edge of the material web eliminates a previously necessary disposal of the cut material, resulting in a significant increase in efficiency while reducing the cost and the use of materials.

Hinsichtlich der konkreten Ausgestaltung der Messerverstellanordnung ergeben sich im Rahmen der Erfindung verschiedene Ausgestaltungsmöglichkeiten. Beispielsweise können die Stellmesser unabhängig voneinander in Querrichtung durch einen Stellmotor, einen Aktuator oder dergleichen beweglich sein, wobei dann durch die Steuerung der äquidistante Abstand zwischen den in Querrichtung aufeinanderfolgenden Schneidmessern eingestellt werden kann.With regard to the specific configuration of the knife adjustment arrangement, different design possibilities arise within the scope of the invention. For example, the adjusters can be independently in the transverse direction be movable by a servomotor, an actuator or the like, in which case can be adjusted by the control of the equidistant distance between the transversely consecutive cutting blades.

Grundsätzlich ist es auch möglich, dass sämtliche Schneidmesser in Querrichtung verschiebbar sind. Alternativ kann dagegen auch vorgesehen sein, dass bis auf ein ortsfest angeordnetes Schneidmesser sämtliche Schneidmesser mit der Messerverstellanordnung in Querrichtung verschiebbar sind. Das eine ortsfest angeordnete Schneidmesser bildet dann einen Fixpunkt, der bei der Bahnsteuerung zu berücksichtigen ist. Ausgehend von dem ortsfest angeordneten Schneidmesser erfolgt dann eine ziehharmonikaartige Verstellung der übrigen Schneidmesser.In principle, it is also possible that all cutting blades are displaceable in the transverse direction. Alternatively, on the other hand, it can also be provided that, with the exception of a stationarily arranged cutting blade, all the cutting knives are displaceable in the transverse direction with the knife adjustment arrangement. The one fixedly arranged cutting blade then forms a fixed point, which must be taken into account in the path control. Starting from the stationary arranged cutting blade then a concertina-like adjustment of the remaining cutting blade.

Das ortsfest angeordnete Schneidmesser kann sich beispielsweise nahe eines Randes der Materialbahn oder vorzugsweise in der Mitte der Materialbahn befinden.The stationarily arranged cutting blade can be located, for example, near an edge of the material web or preferably in the middle of the material web.

Wenn sich das ortsfest angeordnete Schneidmesser nahe eines Randes der Materialbahn befindet, ist die Materialbahn so zu steuern, dass zwischen dem ortsfest angeordneten Schneidmesser und dem benachbarten Rand der Materialbahn ein erster Streifen mit der gewünschten Breite erzeugt wird, während die übrigen Schneidmesser dann im notwendigen Maße nachgestellt werden. Mit zunehmendem Abstand eines Schneidmessers von dem ortsfest angeordneten Schneidmesser nimmt dann auch der Verstellweg zu.If the stationarily arranged cutting blade is located near an edge of the material web, the material web is to be controlled such that a first strip with the desired width is produced between the stationarily arranged cutting knife and the adjacent edge of the material web, while the remaining cutting knives are then to the required extent be readjusted. With increasing distance of a cutting blade from the stationary blade arranged then also increases the adjustment.

Wenn das ortsfeste Schneidmesser mittig angeordnet ist, wird die Materialbahn zweckmäßigerweise so gesteuert, dass sich in Querrichtung gesehen die Mitte der Materialbahn genau an dem ortsfest angeordneten Schneidmesser befindet, wobei dann die an beiden Seiten anschließenden, in Querrichtung verschiebbaren Schneidmesser im Wesentlichen spiegelsymmetrisch zu einer in Bahnlängsrichtung verlaufenden Symmetrieachse verstellt werden. Bei einer solchen Anordnung ist üblicherweise eine ungerade Anzahl an Schneidmessern vorgesehen.If the stationary cutting blade is arranged centrally, the material web is expediently controlled so that, seen in the transverse direction, the center of the material web is located exactly on the fixedly arranged cutting blade, in which case the adjoining on both sides, displaceable in the transverse direction Cutting knife are adjusted substantially mirror-symmetrical to a running in the web longitudinal direction of symmetry axis. In such an arrangement, an odd number of cutting blades is usually provided.

Wie bereits zuvor erläutert, kann jedes Schneidmesser mit einem zugeordneten Aktuator oder dergleichen versehen sein, um die Messerverstellanordnung zu bilden.As previously explained, each cutting blade may be provided with an associated actuator or the like to form the blade displacement assembly.

Gemäß einer bevorzugten Ausgestaltung der Erfindung weist die Messerverstellanordnung jedoch ein mechanisches Stellglied auf, an welches sämtliche in Querrichtung verschiebbaren Schneidmesser angeschlossen sind, so dass sich ein besonders einfacher Aufbau ergibt, der auch leicht gewartet werden kann.According to a preferred embodiment of the invention, however, the Messerverstellanordnung on a mechanical actuator, to which all movable in the transverse direction cutting blades are connected, so that a particularly simple structure results, which can also be easily maintained.

Beispielsweise kann das Stellglied für jedes daran angeschlossene Schneidmesser eine Führungskulisse aufweisen. Durch eine Bewegung des Stellgliedes werden dann die Schneidmesser über die Führungskulissen in einer vorgegebenen Weise in Querrichtung verschoben.For example, the actuator may have a guide slot for each connected cutting blade. By a movement of the actuator then the cutting blades are moved over the guide slots in a predetermined manner in the transverse direction.

Eine besonders einfache Anordnung ergibt sich, wenn das Stellglied um eine Drehachse mit einem an die Steuerung angeschlossenen Drehantrieb verstellbar angeordnet ist, wobei der Verlauf der Führungskulissen jeweils abhängig von dem Abstand der jeweiligen Führungskulisse zu der Drehachse bestimmt ist. Mit zunehmendem Abstand zu der Drehachse nimmt auch in Querrichtung der Verstellweg für die einzelnen Schneidmesser zu.A particularly simple arrangement results when the actuator is arranged to be adjustable about a rotation axis with a rotary drive connected to the control, wherein the course of the guide slots is determined depending on the distance of the respective guide slot to the rotation axis. With increasing distance to the axis of rotation also increases in the transverse direction of the adjustment for the individual cutting blade.

Wenn in Querrichtung gesehen ein mittleres Schneidmesser ortsfest angeordnet ist und die weiteren Schneidmesser an beiden Seiten symmetrisch anschließen, ist auch die Drehachse in Querrichtung gesehen an dem mittleren Schneidmesser angeordnet.If, viewed in the transverse direction, a central cutting blade is stationary and the other cutting blades connect symmetrically on both sides, is also the axis of rotation seen in the transverse direction arranged on the central cutting blade.

Der Drehantrieb kann beispielsweise über einen Verbindungshebel an das Stellglied angeschlossen sein.The rotary drive can be connected, for example via a connecting lever to the actuator.

Um einen einfachen Aufbau der Materiabahnschneideinrichtung zu erreichen, können auch zumindest die mit der Messerverstellanordnung verschiebbaren Schneidmesser und vorzugsweise sämtliche Schneidmesser an einer in Querrichtung verlaufenden Führungsschiene angeordnet sein.In order to achieve a simple construction of the material-cutting device, at least the cutting blades displaceable with the knife-adjusting arrangement, and preferably all the cutting blades, can also be arranged on a guide rail extending in the transverse direction.

Vorzugsweise weist die Materialbahnschneideinrichtung zwischen 5 und 13 Schneidmesser auf.The material web cutting device preferably has between 5 and 13 cutting blades.

Die Schneidmesser können ohne Einschränkung von Klingen, Schneidrollen oder auch Laser-Schneidwerkzeugen gebildet sein. Vorzugsweise sind die Schneidmesser auf einem Messerträger angeordnet, wobei die Schneidmesser über den Messerträger verstellbar sind. Die Messerträger können dazu in der beschriebenen Weise mit Führungskulissen eines mechanischen Stellgliedes zusammenwirken und/oder auf der Führungsschiene abgestützt sein.The cutting blades can be formed without limitation of blades, cutting rollers or laser cutting tools. Preferably, the cutting blades are arranged on a knife carrier, wherein the cutting blades are adjustable over the knife carrier. The knife carrier can cooperate in the manner described with guide slots of a mechanical actuator and / or be supported on the guide rail.

Gegenstand der Erfindung ist auch ein Verfahren zur Bildung einer Vielzahl von Streifen aus einer Materialbahn mittels der zuvor beschriebenen Materialbahnschneideinrichtung, wobei mit dem zumindest einen Lagesensor die Lage eines Randes der Materialbahn bestimmt wird und wobei in Abhängigkeit der Lage des Randes zumindest ein Teil der Schneidmesser derart mit der Messerverstellanordnung verschoben wird, dass mit n Schneidmessern ohne ein Verschnitt der Materialbahn an ihren Rändern n+1 Streifen gebildet werden, welche vorzugsweise innerhalb eines Toleranzbereiches eine gleiche Breite in Quer-richtung aufweisen. Der Toleranzbereich liegt üblicherweise bei weniger als ± 10 %, vorzugsweise bei weniger als ± 5 % und besonders bevorzugt bei weniger als ± 2 %.The invention also provides a method for forming a plurality of strips from a material web by means of the material web cutting device described above, wherein the position of an edge of the material web is determined by the at least one position sensor and wherein at least a part of the cutting blade in dependence of the position of the edge is shifted with the Messerverstellanordnung that with n cutting blades without a waste of the material web at its edges n + 1 strips are formed, which preferably within a tolerance range an equal width in the transverse direction exhibit. The tolerance range is usually less than ± 10%, preferably less than ± 5%, and more preferably less than ± 2%.

Wenn gewährleistet ist, dass die Materialbahn hinsichtlich ihrer Breite mittig einläuft, ist im Rahmen der Erfindung ein einziger Lagersensor an einem Rand der Materialbahn ausreichend. Hinsichtlich der Schwankungen der Breite ΔB ergibt sich bei einem mittigen Bahnlauf an jeder Seite eine zu erwartende Schwankungsbreite von ΔB/2, wobei der Lagesensor dann hinsichtlich dieser zu erwartenden Schwankungsbreite ΔB/2 mittig angeordnet wird.If it is ensured that the material web enters centrally with regard to its width, a single bearing sensor at one edge of the material web is sufficient in the context of the invention. With regard to the fluctuations of the width .DELTA.B results in a central web run on each side an expected fluctuation of .DELTA.B / 2, wherein the position sensor is then arranged centrally with respect to this expected fluctuation width .DELTA.B / 2.

Grundsätzlich können auch an beiden Rändern der Materialbahn in der beschriebenen Weise Lagesensoren vorgesehen sein, wobei dann auch das Signal der beiden Lagesensoren für eine Steuerung der Materialbahn in Querrichtung genutzt werden kann.In principle, position sensors can also be provided on both edges of the material web in the manner described, in which case the signal of the two position sensors can also be used for controlling the material web in the transverse direction.

Vorzugsweise wird im Rahmen des erfindungsgemäßen Verfahrens als Materialbahn eine elastische Folie zugeführt. Besonders bevorzugt werden die aus der elastischen Folie gebildeten Streifen nachfolgend mit einem Abstand zueinander mit zumindest einer Nonwovenbahn kaschiert, um beispielsweise einen Verbundstoff zu bilden, aus dem elastische Verschlusselemente von Wegwerfartikeln wie Babywindeln abgetrennt werden können.Preferably, an elastic film is fed as material web in the context of the method according to the invention. Particularly preferably, the strips formed from the elastic film are subsequently laminated at a distance from one another with at least one nonwoven web in order, for example, to form a composite from which elastic closure elements of disposable articles such as baby diapers can be separated.

Die Fig. 1 zeigt eine Materialbahnschneideinrichtung zum Zerschneiden einer Materialbahn 1 in eine Vielzahl von Streifen 2 (vgl. Fig. 3). Bei der Materialbahn kann es sich beispielsweise um Papier, eine Folie und vorzugsweise eine elastische Kunststofffolie handeln.The Fig. 1 shows a material web cutting device for cutting a material web 1 in a plurality of strips 2 (see. Fig. 3 ). The material web can be, for example, paper, a film and preferably an elastic plastic film.

Mit einer Zuführung 3 in Form einer Walze wird die Materialbahn 1 in einer Bahnlängsrichtung x bewegt.With a feed 3 in the form of a roller, the material web 1 is moved in a web longitudinal direction x.

Die konkrete Ausgestaltung der Materialbahnschneideinrichtung ergibt sich aus den Fig. 2A bis 2C.The concrete embodiment of the material web cutting device results from the Fig. 2A to 2C ,

Um die Materialbahn 1 in die Streifen 2 zu zerschneiden, sind quer zu der Bahnlängsrichtung x in einer Querrichtung q mehrere Schneidmesser 4, 4' in einem Abstand zueinander angeordnet. Gemäß dem Ausführungsbeispiel der Fig. 2A bis 2C sind insgesamt sieben Schneidmesser 4, 4' vorgesehen, wobei die Materialbahnschneideinrichtung noch zwei weitere Schneidmesser 4 zum Zerschneiden einer breiteren Materialbahn 1 aufnehmen kann (vgl. Fig. 3).In order to cut the material web 1 into the strips 2, a plurality of cutting blades 4, 4 'are arranged at a distance from each other transversely to the web longitudinal direction x in a transverse direction q. According to the embodiment of the Fig. 2A to 2C are a total of seven cutting blades 4, 4 'are provided, wherein the material web cutting device can accommodate two more cutting blades 4 for cutting a wider material web 1 (see. Fig. 3 ).

Aus einer vergleichenden Betrachtung der Fig. 2A mit der Fig. 1 ist ersichtlich, dass die Schneidmesser 4, 4' als Schneidrollen ausgebildet sind, wobei die Schneidrollen über jeweils einen zugeordneten Messerträger 5 auf einer in Querrichtung q verlaufenden Führungsschiene 6 angeordnet sind.From a comparative analysis of the Fig. 2A with the Fig. 1 It can be seen that the cutting blades 4, 4 'are formed as cutting rollers, wherein the Cutting rollers are arranged in each case via an associated knife carrier 5 on a guide rail 6 extending in the transverse direction q.

Erfindungsgemäß ist ein in der Fig. 2 angedeuteter Lagesensor 7 an zumindest einem Rand der Materialbahn 1 vorgesehen, wobei der Lagesensor 7 an eine nicht dargestellte Steuerung angeschlossen ist. Des Weiteren umfasst die Materialbahnschneideinrichtung gemäß den Fig. 2A bis 2C eine Messerverstellanordnung 8, welche gemäß dem Ausführungsbeispiel ein um eine Drehachse D drehbares Stellglied 9 aufweist.According to the invention in the Fig. 2 indicated position sensor 7 is provided on at least one edge of the material web 1, wherein the position sensor 7 is connected to a controller, not shown. Furthermore, the material web cutting device according to the Fig. 2A to 2C a Messerverstellanordnung 8, which according to the embodiment has a rotatable about an axis D actuator 9.

Die Drehachse D befindet sich unterhalb eines ortsfest angeordneten Schneidmessers 4', also in Querrichtung q gesehen an derselben Position wie das ortsfest angeordnete Schneidmesser 4' in der Mitte der Materialbahnschneideinrichtung.The axis of rotation D is located below a fixedly arranged cutting blade 4 ', that is seen in the transverse direction q at the same position as the stationarily arranged cutting blade 4' in the middle of the material web cutting device.

Die weiteren Schneidmesser 4, welche in einer im Wesentlichen symmetrischen Anordnung an beiden Seiten des feststehenden Schneidmessers 4' anschließen, sind in Querrichtung q über die Messerträger 5 auf der Führungsschiene 6 verschiebbar angeordnet.The further cutting blades 4, which connect in a substantially symmetrical arrangement on both sides of the fixed cutting blade 4 ', are arranged displaceably on the guide rail 6 in the transverse direction q via the blade carriers 5.

Um eine gleichmäßige Verstellung der verschiebbar angeordneten Schneidmesser 4 zu bewirken, weist das Stellglied 9 für jedes der daran angeschlossenen Schneidmesser 4 eine angepasste Führungskulisse 10 auf.In order to effect a uniform adjustment of the slidably disposed cutting blade 4, the actuator 9 for each of the cutting blade 4 connected thereto an adapted guide slot 10.

Das um die Drehachse D drehbare Stellglied 9 kann durch einen Drehantrieb 11 verdreht werden, der mit einem Verbindungshebel an einem Ende des Stellgliedes 9 angeschlossen ist.The rotatable about the rotation axis D actuator 9 can be rotated by a rotary drive 11 which is connected to a connecting lever at one end of the actuator 9.

Durch die Form der Führungskulissen 10 wird erreicht, dass die verschiebbar angeordneten Schneidmesser 4 durch eine Verdrehung gleichzeitig aber unterschiedlich stark entlang der Führungsschiene 6 bewegt werden. Konkret nimmt der Stellweg der Schneidmesser 4 mit zunehmendem Abstand von der Drehachse D zu.Due to the shape of the guide slots 10 it is achieved that the displaceably arranged cutting blades 4 are moved at the same time but differently strongly along the guide rail 6 by a rotation. Specifically, the travel of the cutting blade 4 increases with increasing distance from the rotation axis D.

Die Führungskulissen 10 des Stellgliedes 9 sind so geformt, dass durch eine Verdrehung stets ein äquidistanter Abstand zwischen den in Querrichtung aufeinanderfolgenden Schneidmessern 4 eingestellt wird.The guide slots 10 of the actuator 9 are shaped so that always a equidistant distance between the transversely consecutive cutting blades 4 is adjusted by a rotation.

Die Fig. 2B zeigt die Schneidmesser 4, 4' einander angenähert, während gemäß der Fig. 2C durch eine Drehung des Stellgliedes 9 in eine entgegengesetzte Richtung die verschiebbar angeordneten Schneidmesser 4 voneinander entfernt sind.The Fig. 2B shows the cutting blades 4, 4 'approached each other, while according to the Fig. 2C by a rotation of the actuator 9 in an opposite direction, the slidably disposed cutting blade 4 are away from each other.

Der Drehantrieb 11 ist ebenfalls an die nicht dargestellte Steuerung angeschlossen, mit der die Messwerte des Lagesensors 7 verarbeitet werden. Wenn die Materialbahn 1 eine vorgegebene Breite B genau einhält, ergibt sich die in Fig. 2A dargestellte Stellung des Stellgliedes 9. Die außenliegenden Streifen ergeben sich dann durch die äquidistante Anordnung der Schneidmesser 4, 4' in Querrichtung q ohne einen seitlichen Beschnitt. Gemäß der Fig. 2A werden also insgesamt mit n = sieben Schneidmessern 4, 4' n+1 = acht Streifen 2 gebildet. In dem Ausführungsbeispiel gemäß den Fig. 2A bis 2C ist die dargestellte Materialbahnschneideinrichtung nicht voll besetzt, wobei zwei weitere Schneidmesser 4 außen ergänzt werden können, um bei einer dann entsprechend breiteren Materialbahn 1 mit n' = neun Schneidmessern 4, 4' n'+1 = zehn Streifen 2 bilden zu können.The rotary drive 11 is also connected to the control, not shown, with which the measured values of the position sensor 7 are processed. If the material web 1 keeps a predetermined width B exactly, the results in Fig. 2A shown position of the actuator 9. The outer strips then result from the equidistant arrangement of the cutting blades 4, 4 'in the transverse direction q without a lateral trim. According to the Fig. 2A Thus, a total of n = seven cutting blades 4, 4 'n + 1 = eight strips 2 are formed. In the embodiment according to the Fig. 2A to 2C the material web cutting device shown is not fully occupied, with two other cutting blade 4 can be added to the outside to form at a then correspondingly wider material web 1 with n '= nine cutting blades 4, 4' n '+ 1 = ten strips 2.

Wenn die Materialbahn 1 innerhalb einer gewissen Schwankungsbreite von dem Sollwert der Breite B abweicht und schmaler ist, werden die Messer gemäß der Fig. 2B einander angenähert, um eine äquidistante Streifenbreite zu erreichen. Dagegen zeigt die Fig. 2C die Stellung der Schneidmesser 4, 4' für die Materialbahn 1, die innerhalb der Toleranzen breiter ist als der Vorgabewert B.If the material web 1 deviates from the target value of the width B within a certain fluctuation range and is narrower, the knives are moved according to the Fig. 2B approached each other to achieve an equidistant stripe width. In contrast, the shows Fig. 2C the position of the cutting blades 4, 4 'for the material web 1, which is wider within the tolerances than the default value B.

In der Fig. 3 sind (exemplarisch für zehn Streifen) die möglichen Abweichungen dargestellt, wobei sich bei einem genau mittigen Zulauf der Materialbahn 1 an den beiden Rändern eine Variationsbreite von ΔB/2 ergibt.In the Fig. 3 are (exemplary for ten strips) shown the possible deviations, resulting in a precisely central inlet of the material web 1 at the two edges a range of variation of ΔB / 2.

An dem unteren Ende der Fig. 3 ist angedeutet, dass durch die erfindungsgemäße äquidistante Verstellung der verschiebbar angeordneten Schneidmesser 4 die Änderung der Breite ΔB auf sämtliche Streifen 2 verteilt wird. Ausgehend von einer mittleren Breite b der Streifen gilt bei n = neun Schneidmesser 4, 4' und entsprechend n+1 = zehn Streifen 2, dass die Schwankungsbreite der einzelnen Streifen 2 bei lediglich Δb = ΔB/(n+1) liegt, so dass die einzelnen Streifen 2 auch mit einer solchen, vergleichsweise geringen Maßabweichung in der Regel ohne weiteres weiterverarbeitet werden können.At the bottom of the Fig. 3 is indicated that the change of the width .DELTA.B is distributed to all strips 2 by the inventive equidistant adjustment of the slidably disposed cutting blade 4. Starting from a mean width b of the strips, at n = nine cutting blades 4, 4 'and correspondingly n + 1 = ten strips 2, the fluctuation width of the individual strips 2 is only Δb = ΔB / (n + 1), so that the individual strips 2 can usually be processed further with such a comparatively small dimensional deviation as a rule without further ado.

Gemäß der Erfindung wird vorzugsweise eine elastische Folie als Materialbahn 1 zugeführt, aus der dann elastische Streifen 2 gebildet werden, die in einem Abstand zueinander mit zumindest einer Nonwovenbahn in ein Laminat eingebunden werden, welches dann abschnittsweise durch die elastischen Streifen 2 - gegebenenfalls nach einer erstmaligen Aktivierung durch ein Recken - elastisch Eigenschaften aufweisen.According to the invention, an elastic film is preferably fed as material web 1, from which then elastic strips 2 are formed, which are bound at a distance from each other with at least one nonwoven web in a laminate, which then in sections by the elastic strips 2 - optionally after a first Activation by stretching - elastic properties.
