Description

Die Erfindung betrifft eine Wickelvorrichtung zur Aufwicklung einer kontinuierlich zulaufenden Materialbahn auf einen Wickel, umfassend eine Kontaktwalze, über die die Materialbahn führbar und auf den mit der Oberfläche der Kontaktwalze in Kontakt stehenden Wickel überführbar ist.The invention relates to a winding device for winding a continuous material web onto a winding, comprising a contact roller, via which the material web can be guided and transferred to the winding in contact with the surface of the contact roller.

Derartige Wickelvorrichtungen sind vielfältig bekannt und dienen beispielsweise der kontinuierlichen Aufwicklung einer zulaufenden Materialbahn auf Basis einer Kunststofffolie oder einer Kunststoff-Vliesbahn. Bauartbedingt steht bei einer solchen Wickelvorrichtung die Kontaktwalze in einem Oberflächenkontakt zu dem sich ausbildenden Wickel der Materialbahn, d.h. die Materialbahn wird unter teilweiser Umschlingung der Oberfläche der Kontaktwalze über diese geführt und an der Kontaktstelle zum Wickel auf den Wickel übergeben.Such winding devices are widely known and serve, for example, the continuous winding of a tapered material web based on a plastic film or a plastic nonwoven web. Due to the design of such a winding device, the contact roller is in surface contact with the forming web of the web, i. the material web is guided with partial wrapping of the surface of the contact roller over this and transferred to the contact point to the winding on the winding.

Problematisch bei dieser an sich bewährten Bauform einer Wickelvorrichtung sind Durchmesserunterschiede der sich ausbildenden Wickel, die beispielsweise auf Dickenschwankungen der Materialbahn zurückzuführen sind. Diese addieren sich auf dem aufgewickelten Wickel und führen dazu, dass die Kontaktwalze nur noch mit den radial höchsten Punkten des Wickels in Berührung kommt, da aus Stabilitätsgründen die Kontaktwalze eine hohe Steifigkeit aufweisen muss. Bei einem solchen nur noch punktförmigen Kontakt zwischen der Kontaktwalze und dem Wickel entsteht jedoch nachfolgend ein ungleichmäßiger Wickelaufbau bis hin zu so genannten Blockstellen oder Wickelwarzen, was verbesserungswürdig erscheint.The problem with this per se proven design of a winding device are differences in diameter of the forming coils, which are due for example to thickness variations of the web. These add up on the wound roll and cause the contact roller comes into contact only with the radially highest points of the roll, since for stability reasons, the contact roller must have a high rigidity. In such only punctiform contact between the contact roller and the winding, however, arises below uneven winding structure up to so-called block sites or winding warts, which seems to be in need of improvement.

Zur Lösung des gestellten Problems sind in der Vergangenheit bereits Versuche unternommen worden, die Kontaktwalzen mit einer weichen und damit Dickentoleranzen ausgleichenden Oberfläche zu versehen, beispielsweise indem die Kontaktwalze einen Sandwichaufbau mit einem inneren harten Trägerrohr und einem äußeren weichen Mantel erhalten hat. Diese Konstruktionen arbeiten jedoch nicht immer zufriedenstellend. Auch ist es bereits vorgeschlagen worden, Walzen zur Führung der Folienbahnen mit einem textilen Mantel auszuggestalten, der sich jedoch insbesondere im Bereich der Kontaktwalze, zwischen der und dem anliegenden Wickel Friktion besteht, nicht zufriedenstellend verhält.To solve the problem posed attempts have been made in the past to provide the contact rollers with a soft and thus thickness tolerances compensating surface, for example by the contact roller has received a sandwich construction with an inner hard carrier tube and an outer soft shell. However, these designs do not always work satisfactorily. Also, it has already been proposed to design rollers for guiding the film webs with a textile jacket, which, however, in particular in the area of the contact roller between which and the adjacent winding friction does not behave satisfactorily.

Die Erfindung hat sich daher die Aufgabe gestellt, eine Wickelvorrichtung mit Kontaktwalze dahingehend weiterzubilden, dass auch bei ungteichförmigen Wickeln infolge von Durchmessertoleranzen ein besonders gleichmäßiges Wickelergebnis sichergestellt wird.The invention therefore has the task of further developing a winding device with contact roller to the effect that even with ungrounded coils due to diameter tolerances a particularly uniform winding result is ensured.

Zur Lösung dieser Aufgabe wird erfindungsgemäß die Ausbildung einer Wickelvorrichtung gemäß den Merkmalen des Schutzanspruchs 1 vorgeschlagen.To solve this problem, the formation of a winding device according to the features of the protection claim 1 is proposed according to the invention.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Advantageous embodiments and modifications of the invention are the subject of the dependent claims.

Die Erfindung schlägt vor, dass die Kontaktwalze der Wickelvorrichtung ein Trägerrohr und außenseitig über das Trägerrohr vorstehende Fasern umfasst, welche die Oberfläche der Kontaktwalze ausbilden, wobei die Fasern sich im Wesentlichen quer zu einer Längsachse der Kontaktwalze erstrecken, dergestalt, dass die Fasern mit einem ersten Ende am Trägerrohr fixiert sind und mit ihrem anderen, freien Ende die Oberfläche der Kontaktwalze definieren. Das Trägerrohr, welches aus einem ausreichend biegesteifen formstabilen Material, wie Stahl, Aluminium oder CFK gebildet ist, weist demnach erfindungsgemäß im Bereich seiner Oberfläche, über die die Materialbahn geführt wird, vorstehende Fasern auf, auf deren freien Enden aufliegend die Materialbahn auf ihrem Weg zum Wickel geführt wird. Aufgrund der Elastizität derartiger Fasern wird der gesamten Kontaktwalze eine sehr hohe Elastizität verliehen, die die Walze in die Lage versetzt, Durchmessertoleranzen der Wickel auf überraschend einfache und effektive Weise auszugleichen. Auch große Durchmesserschwankungen stellen kein Problem dar. Gleichzeitig verleihen die elastischen Fasern der vorgeschlagenen Kontaktwalze gemäß der Erfindung eine außerordentlich gute Dämpfungseigenschaft.The invention proposes that the contact roller of the winding device comprises a carrier tube and fibers projecting on the outside over the carrier tube, which form the surface of the contact roller, wherein the fibers extend substantially transversely to a longitudinal axis of the contact roller, such that the fibers with a first End are fixed to the support tube and define the surface of the contact roller with its other, free end. The support tube, which is formed from a sufficiently rigid dimensionally stable material, such as steel, aluminum or CFRP, according to the invention in the region of its surface over which the material web is guided, protruding fibers, resting on the free ends of the material web on its way to Winding is performed. Due to the elasticity of such fibers, the entire contact roller is given a very high elasticity, which enables the roller to compensate for diameter tolerances of the coils in a surprisingly simple and effective manner. Also, large diameter variations pose no problem. At the same time, the elastic fibers of the proposed contact roller according to the invention provide an extremely good damping property.

Nach einem Vorschlag der Erfindung sind die Fasern der Kontaktwalze in einer Vielzahl diskreter Faserbündel zusammengefasst, was die Fertigung als auch die Beeinflussung des Eigenschaftsbildes der Fasern erleichtert.According to one proposal of the invention, the fibers of the contact roller are combined in a plurality of discrete fiber bundles, which facilitates the manufacture as well as influencing the property pattern of the fibers.

Spezifische Eigenschaften der erfindungsgemäß vorgeschlagenen Kontaktwalze können durch die Wahl des Faserwerkstoffes, der Faserlänge, Faserdicke, Faserform und Schränkung variiert werden, was nachfolgend näher erläutert wird.Specific properties of the contact roller proposed according to the invention can be varied by the choice of the fiber material, the fiber length, fiber thickness, fiber shape and pitch, which will be explained in more detail below.

So ist nach einem Vorschlag der Erfindung vorgesehen, dass die Fasern der Kontaktwalze eine Länge von 1 mm bis 250 mm aufweisen. Im Rahmen der Erfindung ist es sowohl möglich, ausschließlich Fasern einheitlicher Länge wie auch Fasern unterschiedlicher Länge auf einer Kontaktwalze einzusetzen.Thus, it is provided according to a proposal of the invention that the fibers of the contact roller have a length of 1 mm to 250 mm. In the context of the invention, it is both possible to use only fibers of uniform length as well as fibers of different lengths on a contact roller.

Nach einem weiteren Vorschlag der Erfindung sind die Fasern der Kontaktwalze in einem Durchmesser von 0,001 mm bis 1,0 mm ausgeführt, wobei auch hier vorgesehen sein kann, ausschließlich Fasern gleichen Durchmessers, wie auch Fasern unterschiedlichen Durchmessers auf einer Kontaktwalze zur Anwendung zu bringen.According to a further proposal of the invention, the fibers of the contact roller are designed in a diameter of 0.001 mm to 1.0 mm, which may also be provided here to bring only fibers of the same diameter, as well as fibers of different diameters on a contact roller for the application.

Fasern mit einer größeren Länge und/oder geringerem Durchmesser verleihen der Oberfläche der erfindungsgemäß vorgeschlagenen Kontaktwalze eine höhere Nachgiebigkeit bzw. Elastizität.Fibers having a greater length and / or smaller diameter impart a higher compliance or elasticity to the surface of the contact roller proposed according to the invention.

Die Fasern der erfindungsgemäß vorgeschlagenen Kontaktwalze können auf Basis eines Kunststoffes oder auch auf Basis von Tierhaar gebildet sein, wodurch sich weitere Einflussmöglichkeiten auf das Eigenschaftsbild ergeben. Nach einem Vorschlag der Erfindung können die Fasern elektrisch leitfähig ausgebildet bzw. ausgerüstet werden, um der Kontaktwalze eine elektrische Leitfähigkeit zu verleihen und beispielsweise statischen Aufladungen entgegenzuwirken.The fibers of the contact roller proposed according to the invention may be formed on the basis of a plastic or even based on animal hair, which results in further possibilities of influencing the property pattern. According to a proposal of the invention, the fibers can be made electrically conductive or equipped to give the contact roller an electrical conductivity and, for example, counteract static charges.

In Anwendungsfällen, in denen eine elektrische Aufladung der Materialbahn hingegeben gewünscht ist, kann durch entsprechende Auswahl des Materials für die Fasern auch eine elektrische Aufladung der Materialbahn erzeugt werden. Beispiele für geeignete Materialien zur Ausbildung von die Materialbahn aufladenden Fasern sind Polyamid-Kunststoffe.In applications in which an electrical charge of the material web is desired, it is also possible by electrical selection of the material for the fibers to generate an electrical charge on the material web. Examples of suitable materials for forming the web charging fibers are polyamide plastics.

Darüber hinaus können die Fasern zur Oberfläche des Trägerrohres geschränkt angeordnet werden, d.h. entweder in Drehrichtung oder entgegen der Drehrichtung der Kontaktwalze geneigt aus der Oberfläche des Trägerrohres hervortreten.In addition, the fibers can be placed confined to the surface of the support tube, i. either in the direction of rotation or counter to the direction of rotation of the contact roller inclined emerge from the surface of the support tube.

Gleichermaßen ist es auch möglich, die Fasern in Breitenrichtung der Kontaktwalze, d.h. in Richtung der Längsachse derselben zu schränken, so dass auch ein Breitstreckeffekt auf die aufzuwickelnde Materialbahn ausübbar ist.Similarly, it is also possible for the fibers in the width direction of the contact roller, i. in the direction of the longitudinal axis of the same restrict, so that a spreading effect on the wound material web is exercised.

Die geschränkten Fasern können sowohl eine geradlinige als auch eine gebogene Längserstreckung aufweisen.The constrained fibers can have both a straight and a curved longitudinal extent.

Nach einem weiteren Vorschlag der Erfindung können die Fasern der Kontaktwalze auch gekräuselt ausgeführt werden, wodurch sich eine höhere Faserdichte an der Oberfläche der Kontaktwalze erreichen lässt.According to a further proposal of the invention, the fibers of the contact roller can also be crimped, whereby a higher fiber density can be achieved on the surface of the contact roller.

Nach einem weiteren Vorschlag der Erfindung ist das Trägerrohr der erfindungsgemäßen Wickelvorrichtung entlang seiner Längserstreckung in mehrere Segmente unterteilt, die jeweils Fasern außenseitig vorstehend tragen und gemeinsam die Kontaktwalze bilden. Bei dieser Ausgestaltung der Erfindung wird die Kontaktwalze der erfindungsgemäßen Wickelvorrichtung somit nicht von einem einteilig ausgeführten Trägerrohr mit außenseitig vorstehenden Fasern oder Faserbündeln gebildet, sondern das Trägerrohr setzt sich seinerseits aus einer Vielzahl von aneinander gefügten Segmenten zusammen, welche gemeinsam die Kontaktwalze bilden.According to a further proposal of the invention, the support tube of the winding device according to the invention is divided along its longitudinal extent into several segments, each carrying the fibers on the outside protruding and together form the contact roller. In this embodiment of the invention, the contact roller of the winding device according to the invention is thus not formed by a one-piece running carrier tube with fibers or fiber bundles protruding outside, but the support tube is in turn composed of a plurality of segments joined together, which together form the contact roller.

Bei einer solchen vorangehend erläuterten Ausgestaltung des Trägerrohrs der erfindungsgemäßen Wickelvorrichtung mit einer segmentierten Unterteilung desselben lassen sich auf einfache Weise Kontaktwalzen unterschiedlicher Walzenbreite herstellen, da dann lediglich die entsprechende Anzahl an Segmenten, die standardisierte Breite aufweisen können, aneinander gefügt werden müssen, was die Produktion vereinfacht.In such an above-explained embodiment of the support tube of the winding device according to the invention with a segmented subdivision of the same can be produced contact rollers of different roll width in a simple manner, since then only the corresponding number of segments, which may have standardized width, must be joined together, which simplifies the production ,

Auch kann auf einfache Weise eine Anpassung der Kontaktwalze an wechselnde Produktbreiten der auf der erfindungsgemäßen Wickelvorrichtung verarbeiteten Materialbahnen vornehmen.Also can easily make an adjustment of the contact roller to changing product widths of processed on the winding device according to the invention material webs.

Darüber hinaus besteht die Möglichkeit, im Falle des Verschleißes der auf den Trägerrohr-Segmenten angeordneten Fasern bzw. Faserbündeln gezielt lediglich diejenigen Segmente auszutauschen, die Verschleiß unterliegen, so dass die Wartungskosten reduziert werden.In addition, in the case of wear of the fibers or fiber bundles arranged on the carrier tube segments, it is possible to selectively exchange only those segments which are subject to wear, so that the maintenance costs are reduced.

Darüber hinaus gestattet der erfindungsgemäße Vorschlag der Ausbildung des Trägerrohrs aus mehreren aneinander gefügten Segmenten eine noch genauere Abstimmung und Anpassung an die jeweils vorherrschenden Produktgegebenheiten. So ist es denkbar, auf allen Segmenten des Trägerrohres gleichartige Fasern anzuordnen, d.h. insbesondere sämtliche Segmente, die zur Ausbildung der Kontaktwalze verwendet werden, übereinstimmend auszuführen. Andererseits ist es aber auch denkbar, die auf den einzelnen Segmenten angeordneten Fasern bzw. Faserbündel unterschiedlich auszubilden etwa im Sinne der vorgenannten Erläuterungen mit unterschiedlicher Faserhärte, und/oder -länge und/oder unterschiedlichem Durchmesser sowie unterschiedlicher Materialauswahl, Schränkung etc. Auch können die einzelnen Segmente in übereinstimmender oder unterschiedlicher Breite ausgeführt sein.In addition, the proposal according to the invention allows the formation of the support tube of a plurality of segments joined together an even more accurate coordination and adaptation to the prevailing product conditions. So it is conceivable to arrange on all segments of the support tube similar fibers, ie in particular all segments that are used to form the contact roller, run consistently. On the other hand, it is also conceivable that on The individual segments arranged fibers or fiber bundles form differently in the sense of the above explanations with different fiber hardness, and / or length and / or different diameters and different material selection, setting, etc. Also, the individual segments can be designed in matching or different widths.

In jedem Fall erreicht man durch einen derartigen segmentierten Aufbau eine hohe Flexibilität und Kostenersparnis.In any case, achieved by such a segmented structure high flexibility and cost savings.

Nach einem weiteren Vorschlag der Erfindung sind die aneinander angrenzenden Segmente des Trägerrohres formschlüssig miteinander verbindbar, etwa indem sie in ihren aneinander angrenzenden Bereichen mit Eingdffsyorsprüngen und korrespondierenden Vertiefungen ausgerüstet sind, um einen formschlüssigen Eingriff nach Art einer Stimtlächenverzahnung zu gewährleisten. Die in Längserstreckung des Trägerrohres jeweils endseitig zum Liegen kommenden Segmente, d.h. die äußeren Segmente des Trägerrohres können durch entsprechende Spannmittel gegeneinander verspannt werden.According to a further proposal of the invention, the adjoining segments of the support tube are positively connected to each other, for example by being equipped in their adjoining areas with Eindffsyorsprüngen and corresponding recesses to ensure a positive engagement in the manner of a toothed teeth. The segments lying in the longitudinal extension of the support tube at each end lying, i. the outer segments of the support tube can be braced against each other by appropriate clamping means.

Aus den Figuren 2 und 3 ist schematisch eine Wickelvorrichtung zur Aufwicklung einer kontinuierlich zulaufenden Materialbahn 2, beispielsweise einer aus einer Extrusionseinrichtung stammenden Folienbahn dargestellt.
Diese wird in der Wickelvorrichtung unter teilweiser Umschlingung der Oberfläche über eine Kontaktwalze 1 geführt, die in oberflächlichem Kontakt zu einem Wickel 3 steht, der von der aufgewickelten Materialbahn 2 gebildet wird.
Die Drehrichtung der Kontaktwalze 1 ist mit Pfeil D gekennzeichnet.From the FIGS. 2 and 3 is schematically shown a winding device for winding a continuously tapered material web 2, for example, originating from an extrusion device film web.
This is guided in the winding device with partial wrapping of the surface via a contact roller 1, which is in superficial contact with a winding 3, which is formed by the wound material web 2.
The direction of rotation of the contact roller 1 is indicated by arrow D.

Wie in näheren Einzelheiten aus der Darstellung gemäß Figur 1 ersichtlich, umfasst die Kontaktwalze 1 ein beispielsweise aus Edelstahl gefertigtes biegesteifes Trägerrohr 10, welches an seinen beiden in Richtung der Längsachse L liegenden Enden Lagerzapfen 11 für die Lagerung in beispielsweise aus den Figuren 4 bis 6 ersichtlichen Drehlagern 4 aufweist. Anstelle der hier dargestellten Lagerzapfen 11 ist selbstverständlich auch eine Innenlagerung der Kontaktwalze 1 denkbar.As shown in more detail in the illustration according to FIG. 1 can be seen, the contact roller 1 comprises an example made of stainless steel rigid support tube 10, which at its two ends lying in the direction of the longitudinal axis L journals 11 for storage in for example from the FIGS. 4 to 6 has apparent pivot bearings 4. Instead of the bearing pin 11 shown here, of course, an inner bearing of the contact roller 1 is conceivable.

Außenseitig auf das Trägerrohrs 10 sind Fasern 12 aufgebracht, die jeweils mit einer bestimmten Anzahl zu diskreten Faserbündeln 13 zusammengefasst sind. Jede Faser 12 der Faserbündel 13 erstreckt sich dabei im Wesentlichen in Richtung einer Achse T, die quer zur Längsachse L der Kontaktwalze 1 verläuft, d.h. die Fasern 12 sind mit ihrem ersten Ende 121 am Trägerrohr 10 fixiert und mit ihrem anderen, freien Ende 120 stehen sie Ober das Trägerrohr 10 hervor und definieren die Oberfläche 100 der Kontaktwalze 1, über die die Materialbahn 2 zu dem Wickel 3 geführt und an diesen abgegeben wird.On the outside of the support tube 10 fibers 12 are applied, which are each combined with a certain number to discrete fiber bundles 13. Each fiber 12 of the fiber bundles 13 extends substantially in the direction of an axis T, which extends transversely to the longitudinal axis L of the contact roller 1, ie the fibers 12 are fixed with their first end 121 on the support tube 10 and stand with its other, free end 120 They protrude above the support tube 10 and define the surface 100 of the contact roller 1, over which the material web 2 is guided to the winding 3 and delivered to this.

Aufgrund der den Fasern 12 innewohnenden Elastizität ist somit die gesamte Oberfläche 100 der Kontaktwalze 1 elastisch nachgiebig und in der Lage, Durchmessertoleranzen über die Breite des sich ausbildenden Wickels 3 auszugleichen und einen über die gesamte Breite der Kontaktwalze 1 durchgehenden Kontakt zum Wickel 3 auch bei großen Durchmesserschwankungen entlang dessen Längsachse sicherzustellen.Due to the inherent elasticity of the fibers 12, the entire surface 100 of the contact roller 1 is thus elastically yielding and capable of compensating for diameter tolerances across the width of the forming roll 3 and a continuous contact over the entire width of the contact roll 1 to the roll 3, even at large Ensure diameter variations along its longitudinal axis.

Im Ausführungsbeispiel gemäß Figur 1 erstrecken sich die Fasern 12 abgesehen von einer leicht kegeligen Ausrichtung zueinander innerhalb einzelner Faserbündel 13 im Wesentlichen senkrecht zur Längsachse L der Kontaktwalze 1 und jeweils geradlinig, wo hingegen im Ausführungsbeispiel gemäß Figur 2 die einzelnen Fasern 12 eine Schränkung aufweisen, dahingehend, dass die freien Enden 120 der einzelnen Fasern 12 in Drehrichtung D der Kontaktwalze weisen.In the embodiment according to FIG. 1 extend the fibers 12 apart from a slightly conical orientation to each other within individual fiber bundles 13 substantially perpendicular to the longitudinal axis L of the contact roller 1 and each straight, where, however, in accordance with the embodiment FIG. 2 the individual fibers 12 have a twist, in that the free ends 120 of the individual fibers 12 point in the direction of rotation D of the contact roller.

Umgekehrt ist es im Ausfühfungsbeispiel gemäß Figur 3, hier weisen die freien Enden 120 der Fasern 12 in eine der Drehrichtung D der Kontaktwalze 1 entgegengesetzte Richtung.Conversely, it is in the exemplary embodiment according to FIG. 3 , Here, the free ends 120 of the fibers 12 in a direction of rotation D of the contact roller 1 opposite direction.

Durch diese Schränkung der Fasern 12 kann die Planlage der über die Oberfläche 100 der Kontaktwalze 1 geführten Materialbahn bedeutend gesteigert werden. Auch können die Fasern 12 gekräuselt werden, um die Oberflächenbedeckung der Kontaktwalze 1 mit den Fasern 12 weiter zu verbessern.By this restriction of the fibers 12, the flatness of the guided over the surface 100 of the contact roller 1 material web can be significantly increased. Also, the fibers 12 can be crimped to further improve the surface coverage of the contact roller 1 with the fibers 12.

Das Wickelergebnis einer mit einer solchen Kontaktwalze 1 ausgerüsteten Wickelvorrichtung wird überdies dadurch begünstigt, dass es auf derThe winding result of an equipped with such a contact roller 1 winding device is further favors that it on the

Oberfläche der Kontaktwalze 1 nicht zu Lufteinscttlüssen und Blasenbildung unter der Materialbahn 2 kommen kann. Auch wird einer Anhaftung von z.B. klebrigen Folienbahnen auf der Oberfläche der Kontaktwalze 1 effektiv entgegengewirkt.Surface of the contact roller 1 can not come to Lufteinscttlüssen and blistering under the web 2. Also, an adhesion of e.g. sticky film webs on the surface of the contact roller 1 effectively counteracted.

Im Ausführungsbeispiel gemäß der Figur 4 ist eine Schränkung der Fasern 12 in Richtung der Längsachse, d.h. in Breitenrichtung der Kontaktwalze 1 ersichtlich, wobei ausgehend von einem neutralen mittleren Bereich zu beiden Seiten der Kontaktwalze 1 die Fasern in Richtung der Längsachse L und in bzw. entgegen der Drehrichtung D geneigt angeordnet sind- Durch eine solche Ausrichtung der Fasern 12 wird die Materialbahn 1 während ihrer Führung über die Oberfläche 100 der Kontaktwalze 1 in Breitenrichtung derselben gestreckt, was das Wickelergebnis zusätzlich positiv beeinflusst und auch das Eigenschaftsbild der Materialbahn in einer gewünschten Weise beeinflussen kann.In the embodiment according to the FIG. 4 is a restriction of the fibers 12 in the direction of the longitudinal axis, ie in the width direction of the contact roller 1 can be seen, starting from a neutral central region on both sides of the contact roller 1, the fibers in the direction of the longitudinal axis L and inclined in or against the direction of rotation D. By such an orientation of the fibers 12, the material web 1 is stretched during its guidance over the surface 100 of the contact roller 1 in the width direction thereof, which additionally positively influences the winding result and can also influence the property pattern of the material web in a desired manner.

Aus der Figur 7 ist eine weitere Ausführungsform einer Kontaktwalze 1 ersichtlich.From the FIG. 7 is a further embodiment of a contact roller 1 can be seen.

Im Gegensatz zu der aus der Figur 1 ersichtlichen Kontaktwalze 1, die sich durch einen einstückigen Aufbau des Trägerrohrs 10 mit den darauf außenseitig vorstehenden Fasern 12 auszeichnet, ist beim Ausführungsbeispiel gemäß Figur 7 ausgehend von den beiden Lagerzapfen 11 eine durchgehende gemeinsame Achse 5 vorgesehen, auf die eine Vielzahl von beispielhaft mit 10.1, 10.2, 10.3 gekennzeichneten Segmenten des Trägerrohrs 10 aneinander angrenzend aufgeschoben sind. Die Segmente 10.1, 10.2, 10.3 tragen jeweils außenseitig vorstehend die Fasern 12, wobei die Fasern 12 hinsichtlich Anzahl, Größe, Durchmesser, Material, Härte, Ausrichtung im Vergleich zu den weiteren Segmenten gleich oder unterschiedlich ausgebildet sein können.Unlike the one from the FIG. 1 apparent contact roller 1, which is characterized by a one-piece construction of the support tube 10 with the fibers 12 projecting therefrom on the outside, is in the embodiment according to FIG. 7 starting from the two bearing journals 11, a continuous common axis 5 is provided, onto which a multiplicity of segments of the carrier tube 10, which are marked by way of example with 10.1, 10.2, 10.3, are pushed adjacent to one another. The segments 10.1, 10.2, 10.3 each carry the fibers 12 on the outside, the fibers 12 being able to be identical or different in number, size, diameter, material, hardness, orientation compared to the other segments.

Die jeweils in Längserstreckung L der Kontaktwalze 1 betrachtet endseitigen, d.h. außen liegenden Segmente 10.1 werden über Spannscheiben 50, die auf der gemeinsamen Achse 5 angeordnet sind, gegeneinander verspannt, so dass die aneinander angrenzenden Segmente 10.1, 10.2, 10.3 entlang ihrer Trennfuge aneinander gepresst werden und somit gemeinsam das Trägerrohr 10 mit den außenseitig über das Trägerrohr vorstehenden Fasern 12 bilden.The end-side, ie outer, segments 10. 1, viewed in each case along the longitudinal extension L of the contact roller 1, are braced against one another by means of tensioning disks 50 which are arranged on the common axle 5, so that the adjoining segments 10. 1, 10. 2, 10 Dividing joint are pressed together and thus together form the support tube 10 with the outside on the support tube projecting fibers 12.

In nicht dargestellter Weise kann darüber hinaus zwischen benachbarten Segmenten 10.1, 10.2, 10.3 jeweils eine Stimflächenverzahnung mit korrespondierenden Vorsprüngen und Vertiefungen vorgesehen sein, um eine formschlüssige Verbindung der aneinander angrenzenden Segmente 10.1, 10.2, 10.3 zu gewährleisten.In a manner not shown can also be provided between adjacent segments 10.1, 10.2, 10.3 each have an end face toothing with corresponding projections and depressions to ensure a positive connection of the adjacent segments 10.1, 10.2, 10.3.

Mit einer solchen, aus der Figur 7 ersichtlichen segmentiert aufgebauten Kontaktwalze 1 können unterschiedliche Faserkonfigurationen auf den einzelnen Segmenten zum Einsatz gebracht werden, um eine Anpassung an die Produktgegebenheiten vorzunehmen. Beispielsweise ist es denkbar, zur Durchbiegungskompensatioit der Kontaktwalze 1 an den äußeren Segmenten 10.1 weichere Fasern 12 als an den inneren Segmenten vorzusehen.With such, from the FIG. 7 apparent segmented contact roller 1 different fiber configurations on the individual segments can be used to make an adjustment to the product conditions. For example, it is conceivable to provide softer fibers 12 than for the inner segments for the deflection compensation of the contact roller 1 on the outer segments 10.1.

Auch ist es möglich, im Verschleißfalle gezielt nur diejenigen Segmente auszutauschen, bei denen der verschleißbedingte Austausch angezeigt ist, während andere Segmente weiter genutzt werden können, was den Wartungsaufwand und die Betriebskosten senkt.It is also possible, in the event of wear and tear, to selectively exchange only those segments in which the wear-related replacement is indicated, while other segments can continue to be used, which reduces maintenance and operating costs.

Auch kann auf einfache Weise eine Anpassung der Gesamtbreite der Kontaktwalze 1 vorgenommen werden, etwa bei veränderten Breiten der zu verarbeitenden Materialbahn oder im Rahmen der Serienfertigung derartiger Kontaktwalzen, die aus standardisierten Segmenten aufgebaut werden, wobei lediglich die Anzahl der auf die gemeinsame Achse 5 aufgereihten Segmente verändert wird.Also, an adjustment of the overall width of the contact roller 1 can be made in a simple manner, such as changed widths of the material web to be processed or in the mass production of such contact rollers, which are composed of standardized segments, with only the number of rows 5 on the common axis segments is changed.

Es versteht sich, dass die einzelnen Segmente 10.1, 10.2, 10.3 nicht nur mit gleichen oder unterschiedlichen Fasern 12 als auch mit gleicher oder unterschiedlicher Breite ausgeführt sein können.It is understood that the individual segments 10.1, 10.2, 10.3 can be designed not only with the same or different fibers 12 but also with the same or different widths.

Schließlich ist aus den Darstellungen gemäß den Figuren 5 und 6 noch ersichtlich, dass die Gesamtoberfläche der Kontaktwalze 1 nicht nur zylindrisch,Finally, from the illustrations according to the FIGS. 5 and 6 can still be seen that the total surface of the contact roller 1 not only cylindrical,
