Even if the slats 5 are shown in one piece in the exemplary embodiments, they can also be formed in several parts. In particular, the idea is to design the slats 5 as a slat body with a covering applied to it. This covering can then be optimized for the special requirements of the respective material web 2. These slats 5 grip the web 2, an axial movement of the slat 5 being transmitted to the web 2.

Description

Die Erfindung betrifft eine Walze zum Führen und/oder Breitstrecken einer laufenden Warenbahn, wobei die Walze mindestens einen Tragkörper aufweist. An diesen Tragkörper sind außenseitig Aufnahmen für axial verschiebbare Latten vorgesehen, die die Warenbahn erfassen.The invention relates to a roller for guiding and / or spreading a running web of material, the roller having at least one support body. On the outside of this support body, receptacles for axially displaceable slats are provided, which grasp the web of material.

Aus der DE 1 460 639 A ist eine gattungsgemäße Walze bekannt. Diese besteht aus einem Walzenkörper, in dessen Außenseite Nuten eingeformt sind. In diesen Nuten sind H-förmige Profile eingeschoben, welche elastisch ausgebildet sind. Mit den Außenseiten ergreifen diese Profile die Warenbahn. Durch gegensinniges Verschieben der einzelnen Profile kann die Warenbahn in ihrer Breite gestreckt werden. Diese Walze bildet den Ausgangspunkt der vorliegenden Erfindung.From the DE 1 460 639 A a generic roller is known. This consists of a roller body, in the outside of which grooves are formed. H-shaped profiles, which are elastic, are inserted into these grooves. These profiles grip the material web with the outside. The width of the web can be stretched by moving the individual profiles in opposite directions. This roller forms the starting point of the present invention.

Der Erfindung liegt die Aufgabe zugrunde, eine Walze der eingangs genannten Art zu schaffen, die sich durch eine erhöhte Funktionalität auszeichnet.The invention is based on the object of creating a roller of the type mentioned at the beginning, which is characterized by increased functionality.

Diese Aufgabe wir mit den folgenden Merkmalen gelöst.This task is solved with the following features.

Eine erfindungsgemäße Walze dient zum Führen und/oder Breitstrecken einer laufenden Warenbahn. Unter Führen ist dabei die Lageänderung der Warenbahn quer zu ihrer Laufrichtung zu verstehen, wobei die Warenbahnbreite dabei im Wesentlichen unverändert bleibt. Unter Breitstrecken versteht man dagegen die Dehnung der Warenbahn quer zu ihrer Laufrichtung, wobei die Warenbahnmitte in ihrer Lage im Wesentlichen unverändert bleibt. Selbstverständlich können Führen und Breitstrecken auch in Kombination, also gleichzeitig ausgeführt werden. Die Walze weist mindestens einen Tragkörper auf, der vorzugsweise um eine Achse drehbar gehalten ist. Am Tragkörper sind außenseitig Aufnahmen für Latten vorgesehen, an denen axial verschiebbar Latten gehalten sind. Diese Latten können die Warenbahn außenseitig mittelbar oder unmittelbar erfassen. Zur Erhöhung der Funktionalität der Walze ist am mindestens einen Tragkörper zwischen zwei der Latten mindestens eine hinterschnittene Nut eingeformt, welche zur Aufnahme mindestens eines Funktionsbauteils dient. Dieses mindestens eine Funktionsbauteil kann zwar grundsätzlich wie die Latten axial verschiebbar sein. In der Regel reicht es jedoch aus, das mindestens ein Funktionsbauteil fest mit dem mindestens einen Tragkörper zu verbinden. Das mindestens eine Funktionsbauteil kann durch die gewählte Lage der mindestens einen Nut problemlos zwischen zwei Latten greifen und dadurch die Warenbahn erreichen.A roller according to the invention is used to guide and / or spread a moving web of material. In this context, guiding is understood to mean the change in position of the web of material transversely to its running direction, the web width essentially remaining unchanged. Spreading, on the other hand, means the stretching of the web transversely to its running direction, the position of the web center remaining essentially unchanged. Of course, guiding and spreading can also be carried out in combination, i.e. at the same time. The roller has at least one support body, which is preferably held rotatably about an axis. On the outside of the support body, receptacles for slats are provided on which slats are held in an axially displaceable manner. These slats can directly or indirectly grasp the material web on the outside. To increase the functionality of the roller, at least one undercut groove is formed on the at least one support body between two of the slats, which groove serves to accommodate at least one functional component. This at least one functional component can in principle be axially displaceable like the slats. As a rule, however, it is sufficient to firmly connect the at least one functional component to the at least one support body. Due to the selected position of the at least one groove, the at least one functional component can easily grip between two slats and thereby reach the material web.

Insbesondere unter beengten Platzverhältnissen ist es vorteilhaft, wenn sich die Aufnahmen der Latten mit der mindestens einen Nut zur Aufnahme des Funktionsbauteils in radialer Richtung überlappen. Damit greift ein Befestigungsfuß des mindestens einen Funktionsbauteils - in radialer Richtung gesehen - unter die Latten, so dass auch bei beengten Platzverhältnissen ein ausreichend sicherer Halt des mindestens einen Funktionsbauteils gegeben ist.In particular where space is limited, it is advantageous if the receptacles of the slats with the at least one groove for receiving the functional component overlap in the radial direction. A fastening foot of the at least one functional component thus engages under the slats - viewed in the radial direction - so that the at least one functional component is held in a sufficiently secure manner even in confined spaces.

Um das mindestens eine Funktionsbauteil optimal mit der Walze verbinden zu können, ist es vorteilhaft, wenn die mindestens eine hinterschnittene Nut mindestens einen Gewindetreibkanal aufweist. Damit kann das mindestens eine Funktionsbauteil einfach mit der Walze verschraubt werden. Ein Gewindetreibkanal hat zudem den Vorteil, dass mindestens eine Schraube längs zur mindestens einen hinterschnittenen Nut an jeder beliebigen Stelle einschraubbar ist, ohne dass eine fluchtende Ausrichtung mit einer Gewindebohrung erforderlich wäre.In order to be able to optimally connect the at least one functional component to the roller, it is advantageous if the at least one undercut groove has at least one threaded drive channel. In this way, the at least one functional component can simply be screwed to the roller. A threaded drive channel also has the advantage that at least one screw can be screwed in at any point along the at least one undercut groove without the need for an aligned alignment with a threaded hole.

Zur Erzielung einer platzsparenden Anordnung ist es außerdem vorteilhaft, wenn die mindestens eine Nut mindestens eine S-förmige Hinterschneidung aufweist. Auf diese Weise lässt sich der Platz zwischen der Aufnahme der Latten einerseits und der mindestens einen Nut zur Aufnahme des Funktionsbauteils andererseits optimal ausnutzen. Außerdem ergibt sich auf diese Weise eine günstige Form zum leichten Einschieben des mindestens einen Funktionsbauteils.To achieve a space-saving arrangement, it is also advantageous if the at least one groove has at least one S-shaped undercut. In this way, the space between the reception of the slats on the one hand and the at least one groove for receiving the functional component on the other hand can be optimally used. In addition, this results in a favorable shape for easy insertion of the at least one functional component.

Damit das mindestens eine Funktionsbauteil eine Ausstreifwirkung auf die Warenbahn ausüben kann, ist es günstig, wenn es spitzwinkelig zu einer Warenbahnlaufrichtung angestellte Rippen aufweist, die die Warenbahn erfassen. Auf diese Weise ergibt sich eine vorteilhafte Ausstreifeinrichtung, die insbesondere Kanten der Warenbahn ausrollt und ein Wiedereinrollen verhindert.So that the at least one functional component can exert a wiping effect on the web of material, it is advantageous if it has ribs which are set at an acute angle to a direction of web travel and which grasp the web of material. This results in an advantageous spreading device which, in particular, rolls out the edges of the material web and prevents it from rolling in again.

Alternativ oder zusätzlich kann das mindestens eine Funktionsbauteil auch mindestens eine Bürste aufweisen. Dabei ist es für mehrere Funktionen wichtig, dass die mindestens eine Bürste auch die Warenbahn erfassen kann.Alternatively or additionally, the at least one functional component can also have at least one brush. It is important for several functions that the at least one brush can also grasp the material web.

Insbesondere durch schräg angeordnete Borstenreihen der mindestens einen Bürste ergibt sich eine ausstreifende Wirkung. Hierbei können die Borstenreihen schräg in axialer Richtung angeordnet sein oder ähnlich zu den oben genannten Rippen. Die mindestens eine Bürste drückt sich dabei gegen die Warenbahn und verursacht dabei eine von der Geschwindigkeit der Warenbahn abhängige Reibungskraft. Infolge der schräg angeordneten Borstenreihen wird diese Reibungskraft, welche ursprünglich in Warenbahnlaufrichtung gerichtet ist, in eine Komponente in Richtung der Borstenreihen und eine Komponente quer dazu aufgeteilt. Damit entsteht eine von der Mitte der Warenbahn weg gerichtete Kraft, welche beispielsweise eingerollte Kanten glattstreifen kann. Alternativ oder zusätzlich können die Borsten selbst spitzwinkelig zur Radialrichtung der Walze ausgerichtet sein. Auch hierdurch entsteht eine quer zur Bahnlaufrichtung ausgerichtete Kraft.In particular, the obliquely arranged rows of bristles of the at least one brush produce a spreading effect. Here the Rows of bristles can be arranged obliquely in the axial direction or similar to the ribs mentioned above. The at least one brush presses against the material web and causes a frictional force that is dependent on the speed of the material web. As a result of the inclined rows of bristles, this frictional force, which is originally directed in the direction of travel of the web, is divided into a component in the direction of the rows of bristles and a component transversely thereto. This creates a force that is directed away from the center of the material web and can, for example, smooth out rolled edges. Alternatively or additionally, the bristles themselves can be oriented at an acute angle to the radial direction of the roller. This also creates a force oriented transversely to the direction of travel of the web.

Alternativ oder zusätzlich können die Borstenreihen der mindestens einen Bürste auch derart angeordnet sein, dass sich eine fixierende Wirkung ergibt. Hierunter ist zu verstehen, dass durch die Einwirkung der mindestens einen Bürste verhindert wird, dass sich die Warenbahn nach Verlassen der Walze wieder auf ihre ursprüngliche Breite zusammenzieht. Zur Erzielung einer fixierenden Wirkung ist eine schräg nach außen ausgerichtete Borstenreihe nicht erforderlich. Die Borsten sind aber vorzugsweise derart angeordnet, dass sie mit dem Vektor der Warenbahnlaufrichtung einen stumpfen Winkel einschließen, wodurch die Borsten eine entsprechende Normalkraft auf die Warenbahn ausüben, ohne den Lauf der Warenbahn wesentlich zu behindern.As an alternative or in addition, the rows of bristles of the at least one brush can also be arranged in such a way that a fixing effect results. This means that the action of the at least one brush prevents the material web from contracting again to its original width after leaving the roller. In order to achieve a fixing effect, a row of bristles oriented obliquely outwards is not necessary. The bristles are, however, preferably arranged in such a way that they enclose an obtuse angle with the vector of the web running direction, whereby the bristles exert a corresponding normal force on the web without significantly hindering the running of the web.

Alternativ oder zusätzlich kann das mindestens eine Funktionsbauteil auch eine elektrisch leitende Verbindung zwischen der Warenbahn und dem mindestens einen Tragkörper herstellen. Dies ist insbesondere bei elektrostatisch aufladbaren, isolierenden Warenbahnen wichtig, da auf diese Weise Oberflächenladungen leicht abgeleitet werden können. Derartige Oberflächenladungen können weitere Prozessschritte, denen die Warenbahn unterworfen wird, behindern oder nachfolgende Geräte stören.Alternatively or additionally, the at least one functional component can also produce an electrically conductive connection between the material web and the at least one support body. This is particularly important in the case of electrostatically chargeable, insulating material webs, since surface charges can easily be dissipated in this way. Such Surface charges can hinder further process steps to which the material web is subjected or interfere with downstream devices.

Das mindestens eine Funktionsbauteil kann auch mindestens eine Gleitfläche für die Warenbahn aufweisen. Diese Gleitfläche verhindert, dass sich Kanten der Latten in die Warenbahn eindrücken könnten, so dass die Warenbahn nicht erneut geglättet werden muss. Insbesondere empfindliche Warenbahnen wie Naturseide, dünne Kunststofffolien oder dünne Metallfolien werden auf diese Weise geschont und die Bildung von eingedrückten Lattenkanten verhindert.The at least one functional component can also have at least one sliding surface for the material web. This sliding surface prevents the edges of the slats from being pressed into the material web, so that the material web does not have to be smoothed again. In particular, sensitive material webs such as natural silk, thin plastic foils or thin metal foils are protected in this way and the formation of indented lath edges is prevented.

Insbesondere, wenn der der Walze folgende Prozessschritt eine glatte Warenbahn erfördert, ist die Gleitfläche des Funktionsbauteils vorteilhaft. Alternativ oder zusätzlich kann diese Gleitfläche auch schräg zur Warenbahnlaufrichtung angestellt sein, um auf diese Weise eine ausstreifende Wirkung auf die Warenbahn zu erzielen.In particular, when the process step following the roller requires a smooth web of material, the sliding surface of the functional component is advantageous. As an alternative or in addition, this sliding surface can also be set at an angle to the direction of travel of the web in order to achieve a spreading effect on the web in this way.

Für die Gleitfläche hat es sich als günstig herausgestellt, wenn sie in Umfangsrichtung des mindestens einen Tragkörpers gekrümmt ist. Vorzugsweise liegt die Gleitfläche fluchtend und tangential zu den beiden benachbarten Latten, so dass an der Oberfläche der Walze keinerlei Kanten entstehen, die sich in die Warenbahn eindrücken könnten.It has proven to be favorable for the sliding surface if it is curved in the circumferential direction of the at least one support body. The sliding surface is preferably aligned and tangential to the two adjacent slats, so that no edges whatsoever arise on the surface of the roller which could be pressed into the web of material.

Selbstverständlich können die oben beschriebenen Ausbildungen der Funktionsbauteile auch in beliebiger Weise kombiniert werden, um mehrere Funktionen gleichzeitig zu erfüllen.Of course, the above-described designs of the functional components can also be combined in any way in order to fulfill several functions at the same time.

Der Erfindungsgegenstand wird beispielhaft anhand der Zeichnung erläutert, ohne den Schutzumfang zu beschränken.The subject matter of the invention is explained by way of example with reference to the drawing, without restricting the scope of protection.

Die Figur 1 zeigt eine Schnittdarstellung einer Walze 1 zum Führen bzw. Breitstrecken einer laufenden Warenbahn 2. Um die Details besser erkennen zu können, zeigt die Figur nur einen kleinen Ausschnitt der Walze 1 und der Warenbahn 2. Die Walze 1 weist einen Tragkörper 3 auf, der im Wesentlichen zylindrisch aufgebaut ist. Der Tragkörper 3 ist um eine nicht dargestellte Achse drehbar gehalten, wobei die Achse senkrecht zur Bildebene gemäß Figur 1 ausgerichtet ist.The Figure 1 shows a sectional view of a roller 1 for guiding or spreading a running web 2. In order to be able to see the details better, the figure shows only a small section of the roller 1 and the web 2. The roller 1 has a support body 3, which in the Is constructed essentially cylindrical. The support body 3 is held rotatably about an axis (not shown), the axis being perpendicular to the image plane according to FIG Figure 1 is aligned.

Am Tragkörper 3 sind außenseitig Aufnahmen 4 für Latten 5 vorgesehen, welche axial zum Tragkörper 3 verschiebbar abgestützt sind. Auch wenn die Latten 5 in den Ausführungsbeispielen einstückig dargestellt sind, können diese auch mehrteilig ausgebildet sein. Insbesondere ist daran gedacht, die Latten 5 als Lattenkörper mit einem darauf aufgebrachten Belag auszubilden. Dieser Belag kann dann auf die besonderen Erfordernisse der jeweiligen Warenbahn 2 optimiert werden. Diese Latten 5 erfassen die Warenbahn 2, wobei sich eine axiale Bewegung der Latte 5 auf die Warenbahn 2 überträgt. Damit kann die Warenbahn 2 geführt, also in ihrer Lage verändert und/oder breitgestreckt, also in ihrer Breite verändert werden. Die Aufnahmen 4 sind dabei hinterschnitten ausgebildet, um einen sicheren Halt der Latten 5 in den Aufnahmen 4 zu gewährleisten.On the outside of the support body 3, receptacles 4 for slats 5 are provided, which are supported axially to the support body 3 so as to be displaceable. Even if the slats 5 are shown in one piece in the exemplary embodiments, they can also be formed in several parts. In particular, the idea is to design the slats 5 as a slat body with a covering applied to it. This covering can then be optimized for the special requirements of the respective material web 2. These slats 5 grip the web 2, an axial movement of the slat 5 being transmitted to the web 2. The material web 2 can thus be guided, that is to say changed in its position and / or stretched out, that is to say changed in its width. The receptacles 4 are formed undercut in order to ensure that the slats 5 are held securely in the receptacles 4.

Zwischen den Latten 5 ist im Tragkörper 3 außerdem jeweils eine hinterschnittene Nut 6 vorgesehen, in der ein Funktionsbauteil 7 abgestützt ist. Da der Raum zwischen den Latten 5 in der Regel sehr klein ist, greift die hinterschnittene Nut 6 - in radialer Richtung 8 betrachtet - teilweise unter die Latten 5. In diesem Bereich ist der Tragkörper 3 ausreichend dickwandig ausgebildet, so dass die damit verbundene Materialschwächung des Tragkörpers 3 keine Rolle spielt. Um das Funktionsbauteil 7 leicht in die hinterschnittene Nut 6 einführen bzw. aus dieser herausziehen zu können, ist eine Hinterschneidung 9 S-förmig ausgebildet. Diese Form hat außerdem den Vorteil, dass sie sich platzsparend in den Tragkörper 3 einfügt. In der hinterschnittenen Nut 6 greift ein passend geformter Fuß 10 des Funktionsbauteils 7 ein, welches auf diese Weise sicher im Tragkörper 3 gehalten ist. Dieser Fuß 10 ist vorzugsweise elastisch verformbar ausgebildet, um auf diese Weise einen spielfreien Sitz des Funktionsbauteils 7 in der hinterschnittenen Nut 6 zu gewährleisten. Dies ist insbesondere in jenen Anwendungsfällen wichtig, in denen die Ausrichtung des Funktionsbauteils 7 von Bedeutung ist.In addition, an undercut groove 6, in which a functional component 7 is supported, is provided in each case in the support body 3 between the slats 5. Since the space between the slats 5 is usually very small, the undercut groove 6 - viewed in the radial direction 8 - partially engages under the slats 5. In this area, the support body 3 is sufficiently thick-walled so that the associated material weakening of the Support body 3 does not matter. In order to be able to easily introduce the functional component 7 into the undercut groove 6 or to be able to pull it out of it, an undercut 9 is S-shaped. This shape also has the advantage that it fits into the support body 3 in a space-saving manner. A suitably shaped foot 10 of the functional component 7 engages in the undercut groove 6 and is held securely in the support body 3 in this way. This foot 10 is preferably designed to be elastically deformable in order in this way to seat the functional component without play 7 in the undercut groove 6 to ensure. This is particularly important in those applications in which the alignment of the functional component 7 is important.

Die Figur 2 zeigt eine alternative Ausführungsform der Walze 1, wobei gleiche Bezugszeichen gleiche Teile benennen. Im Folgenden wird lediglich auf die Unterschiede zur Ausführungsform gemäß Figur 1 eingegangen.The Figure 2 shows an alternative embodiment of the roller 1, wherein the same reference numerals designate the same parts. Only the differences from the embodiment according to FIG Figure 1 received.

Bei der Ausführungsform gemäß Figur 2 ist die ist hinterschnittene Nut 6 als Gewindetreibkanal 11 ausgebildet, so dass auf diese Weise sehr einfach ein nicht dargestelltes Funktionsbauteil mit der Walze 1 verschraubt werden kann. Auf diese Weise ergibt sich eine gute Fixierung des Funktionsbauteils an der Walze 1 auch in axialer Richtung. Dies kann insbesondere dann von Bedeutung sein, wenn, das Funktionsbauteil axiale Kräfte auf die laufende Warenbahn 2 übertragen soll.In the embodiment according to Figure 2 the undercut groove 6 is designed as a threaded drive channel 11, so that in this way a functional component (not shown) can be screwed to the roller 1 very easily. This results in a good fixation of the functional component on the roller 1, also in the axial direction. This can be of particular importance when the functional component is to transmit axial forces to the moving material web 2.

Das Funktionsbauteil 7 wird anhand der Darstellungen gemäß den Figuren 3 bis 9 näher erläutert:
Die Figur 3 zeigt ein Funktionsbauteil 7, an dem außenseitig Rippen 20 angeordnet sind. Diese Rippen 20 sind spitzwinkelig zu einer Warenbahnlaufrichtung 21 angestellt und erzeugen auf diese Weise auf die Warenbahn 2 eine nach außen gerichtete Kraft. Diese Rippen 20 sorgen zum Beispiel für ein Ausrollen von eingerollten Warenbahnkanten bzw. verhindern ein Wiedereinrollen der Kanten. Zu diesem Zweck sind die Rippen 20 im Bereich des anderen Gegenendes spiegelsymmetrisch zu den dargestellten Rippen 20 angeordnet, um entsprechend linke und rechte Warenbahnkanten auszurollen.The functional component 7 is based on the representations according to Figures 3 to 9 explained in more detail:
The Figure 3 shows a functional component 7 on which ribs 20 are arranged on the outside. These ribs 20 are set at an acute angle to a web running direction 21 and in this way generate an outwardly directed force on the web 2. These ribs 20 ensure, for example, that rolled-up web edges are rolled out or prevent the edges from rolling in again. For this purpose, the ribs 20 are arranged in the area of the other opposite end mirror-symmetrically to the ribs 20 shown in order to roll out left and right web edges accordingly.

Die Figur 4 zeigt eine alternative Ausführungsform des Funktionsbauteils 7. Bei diesem sind die Rippen 20 durch Bürsten 30 ersetzt. Diese Bürsten 30 können einerseits eine Ausstreifwirkung und/oder eine Fixierwirkung auf die Warenbahn 2 ausüben. Unter Fixierwirkung versteht man dabei eine Maßnahme die dafür sorgt, dass die Warenbahn 2 in der breitgestreckten Lage verbleibt.The Figure 4 shows an alternative embodiment of the functional component 7. In this, the ribs 20 are replaced by brushes 30. These brushes 30 can on the one hand exert a spreading effect and / or a fixing effect on the web 2. A fixing effect is understood to mean a measure that ensures that the web 2 remains in the extended position.

Die Bürsten 30 sind dabei derart schräggestellt, dass sie jeweils zum nächstliegenden Walzenende hin geneigt sind. Hierdurch wird die Ausstreifwirkung entsprechend erhöht. Alternativ könnten die Bürsten 30 auch in radialer Richtung ausgerichtet sein, so dass die Bürsten 30 nur noch aufgrund ihrer Anordnung quer zur Laufrichtung eine entsprechende Ausstreifwirkung aufweisen. Als weitere Alternative ist außerdem daran gedacht, die rippenartige Schrägstellung der Bürsten 30 nicht zu nutzen und stattdessen die Bürsten 30 axial hintereinander anzuordnen.The brushes 30 are inclined in such a way that they are each inclined towards the nearest end of the roller. This increases the spreading effect accordingly. Alternatively, the brushes 30 could also be aligned in the radial direction, so that the brushes 30 only have a corresponding wiping effect due to their arrangement transverse to the running direction. As a further alternative, it is also contemplated not to use the rib-like inclination of the brushes 30 and instead to arrange the brushes 30 axially one behind the other.

Die Figur 5 zeigt eine weitere Ausführungsform des Funktionsbauteils 7. Dieses weist im Außenbereich eine Gleitfläche 40 auf, die tangential und fluchtend zu den beiderseits angrenzenden Latten 5 ausgebildet ist. Diese Gleitfläche 40 verhindert zum Beispiel das Entstehen von eingedrückten Lattenkanten. Diese Gleitfläche 40 ist insbesondere in jenen Fällen von Bedeutung, in denen die Latten 5 geteilt sind, um neben einer Führungsauch eine Ausbreitwirkung auf die Warenbahn 2 zu erzielen. Durch diese Teilung ergibt sich jedoch eine Lücke, über die die Warenbahn 2 nicht abgestützt ist. Diese Lücke kann vorteilhaft von der Gleitfläche 40 des Funktionsbauteils 7 überbrückt werden, um einer erhöhten Beanspruchung der Warenbahn 2 vorzubeugen.The Figure 5 shows a further embodiment of the functional component 7. This has a sliding surface 40 in the outer area, which is tangential and aligned with the slats 5 adjoining on both sides. This sliding surface 40 prevents, for example, the occurrence of indented slat edges. This sliding surface 40 is particularly important in those cases in which the slats 5 are divided in order to achieve a spreading effect on the web 2 in addition to a guide. However, this division results in a gap over which the web 2 is not supported. This gap can advantageously be bridged by the sliding surface 40 of the functional component 7 in order to prevent increased stress on the material web 2.

Die Figur 6 zeigt eine räumliche Darstellung eines weiteren Funktionsbauteils 7. Dieses Funktionsbauteil 7 weist elektrisch leitende Bürsten 12, 13 auf, die die Warenbahn 2 und/oder mindestens eine der Latten 5 berührt. Auf diese Weise ergibt sich eine elektrische Verbindung zur Walze 1. Damit wird eine statische Aufladung der laufenden Warenbahn 2 bzw. der Latte 5 verhindert, welche zu elektrischen Überschlägen bzw. Beeinträchtigung der Funktion nachfolgender elektrischer Baugruppen führen könnte. Eine derartige Maßnahme ist nur bei elektrisch isolierenden Warenbahnen 2 zweckmäßig, zumal selbst geringfügig leitende Warenbahnen 2 keinerlei elektrische Aufladungsphänomene zeigen.The Figure 6 shows a three-dimensional representation of a further functional component 7. This functional component 7 has electrically conductive brushes 12, 13 that touch the material web 2 and / or at least one of the slats 5. This results in an electrical connection to the roller 1. This prevents static charging of the moving web 2 or the lath 5, which could lead to electrical flashovers or impairment of the function of subsequent electrical assemblies. Such a measure is only useful in the case of electrically insulating material webs 2, especially since even slightly conductive material webs 2 do not show any electrical charging phenomena.

Die elektrisch leitenden Bürsten 12 berühren dabei die Warenbahn 2 unmittelbar, während die elektrisch leitenden Bürsten 13 lediglich eine elektrische Verbindung mit den Latten 5 herstellen. Je nach Anwendungsfall kann auch auf die Bürsten 12 oder 13 verzichtet werden.The electrically conductive brushes 12 are in direct contact with the material web 2, while the electrically conductive brushes 13 merely establish an electrical connection with the slats 5. Depending on the application, the brushes 12 or 13 can also be dispensed with.

Die Figur 7 zeigt eine räumliche Darstellung eines weiteren Funktionsbauteils 7 mit einer Stützfunktion. Dieses Funktionsbauteil 7 unterstützt dabei in radialer Richtung innenseitig die Latten 5. Dies ist bei hohen Lasten auf den Latten 5 wichtig, um ein Verbiegen der Latten 5 zu vermeiden. Oberseitig weist dieses Funktionsbauteil 7 Gleitflächen 40 auf.The Figure 7 shows a three-dimensional representation of a further functional component 7 with a support function. This functional component 7 supports the slats 5 on the inside in the radial direction. This is important in the case of high loads on the slats 5 in order to prevent the slats 5 from bending. This functional component 7 has sliding surfaces 40 on the upper side.

Die Figur 8 zeigt eine räumliche Darstellung eines weiteren Funktionsbauteils 7 mit einer Transportsicherungsfunktion. Das Funktionsbauteil 7 ist ähnlich zur Ausführungsform gemäß Figur 5 aufgebaut, wobei eine Stütze 50 radial beträchtlich über die Latten 5 übersteht. Auf diese Weise wird während des Transports der Walze 1 zuverlässig verhindert, dass unerwünschte Kräfte auf die Latten 5 einwirken. Für den Betrieb muss dieses Funktionsbauteil 7 demontiert werden.The Figure 8 shows a three-dimensional representation of a further functional component 7 with a transport security function. The functional component 7 is similar to the embodiment according to FIG Figure 5 constructed, with a support 50 protruding radially considerably over the slats 5. In this way, during the transport of the roller 1, it is reliably prevented that undesired forces act on the slats 5. This functional component 7 must be dismantled for operation.

Die Figur 9 zeigt eine räumliche Darstellung eines weiteren Funktionsbauteils 7 mit einer Reinigungsfunktion. Dieses Funktionsbauteil 7 weist im radial außen liegenden Bereich näherungsweise in Umfangsrichtung der Walze 1 ausgerichtete Borsten 60 auf, die die Latten 5 während ihrer axialen Bewegung reinigen. Grundsätzlich können die Borsten 60 mit einem physikalischen oder chemischen Reinigungsmittel versehen sein. In der Regel reicht jedoch die mechanische Wirkung der Borsten völlig aus, um die Latten 5 zu reinigen.The Figure 9 shows a three-dimensional representation of a further functional component 7 with a cleaning function. In the radially outer area, this functional component 7 has bristles 60 which are oriented approximately in the circumferential direction of the roller 1 and which clean the slats 5 during their axial movement. In principle, the bristles 60 can be provided with a physical or chemical cleaning agent. In the As a rule, however, the mechanical action of the bristles is completely sufficient to clean the slats 5.

Die dargestellten und beschriebenen Ausführungsformen des Funktionsbauteils 7 können auch in beliebiger Kombination eingesetzt werden.The illustrated and described embodiments of the functional component 7 can also be used in any combination.
