Definitions
- the invention relates to a roller for guiding and/or spreading a running web of material, the roller having at least one supporting body. On the outside of this supporting body, there are receptacles for axially displaceable slats that grasp the web.
- a generic roller according to the preamble of claim 1 is known. This consists of a roller body with grooves formed on the outside. H-shaped profiles, which are designed to be elastic, are inserted into these grooves. These profiles grip the web with the outer sides. By moving the individual profiles in opposite directions, the width of the web can be stretched. This roller forms the starting point of the present invention.
- the invention is based on the object of creating a roller of the type mentioned at the outset, which is characterized by increased functionality.
- a roller according to the invention serves to guide and/or spread a running web of material. Guiding is to be understood as meaning the change in position of the web of material transversely to its running direction, with the width of the web of material remaining essentially unchanged. By spreading, on the other hand, one understands the stretching of the web of material transversely to its direction of travel, with the position of the center of the web of material remaining essentially unchanged. Of course, leading and spreading can also be done in combination, i.e. at the same time.
- the roller has at least one supporting body, which is preferably held so as to be rotatable about an axis.
- receptacles for slats are provided on the outside, on which slats are held in an axially displaceable manner. These slats can grasp the material web on the outside directly or indirectly.
- at least one undercut groove is formed on at least one support body between two of the slats, which 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 supporting body.
- the at least one functional component can easily reach between two slats due to the selected position of the at least one groove and thus reach the web.
- the at least one undercut groove has at least one threaded drive channel.
- the at least one functional component can thus be simply screwed to the roller.
- a thread drive channel also has the advantage that at least one screw can be screwed in at any desired point along the at least one undercut groove, without the need for alignment with a threaded hole.
- the at least one groove has at least one S-shaped undercut. In this way, the space between the accommodation of the slats on the one hand and the at least one groove for accommodating the functional component on the other hand can be optimally utilized. In addition, this results in a favorable shape for easy insertion of the at least one functional component.
- the at least one functional component In order for the at least one functional component to be able to exert a stripping effect on the web of material, it is advantageous if it has ribs which are set at an acute angle to a direction of travel of the web of material and grip the web of material. This results in an advantageous stripping device which, in particular, rolls out edges of the material web and prevents it from rolling up again.
- the at least one functional component can also have at least one brush. It is important for several functions that at least one brush can also grasp the web.
- a wiping effect results in particular from the obliquely arranged rows of bristles of the at least one brush.
- Rows of bristles may be arranged obliquely in the axial direction or similar to the ribs mentioned above.
- the at least one brush presses against the web of material and causes a frictional force that is dependent on the speed of the web of material.
- this frictional force which is originally directed in the running direction of the web, is divided into a component in the direction of the rows of bristles and a component transverse thereto. This creates a force directed away from the center of the material web, which can smooth rolled edges, for example.
- the bristles themselves can be aligned at an acute angle to the radial direction of the roller. This also creates a force that is aligned transversely to the running direction of the web.
- the rows of bristles of the at least one brush can also be arranged in such a way that there is a fixing effect. This means that the action of the at least one brush prevents the material web from contracting back to its original width after leaving the roller.
- a row of bristles oriented obliquely outwards is not required.
- the bristles are preferably arranged in such a way that they enclose an obtuse angle with the vector of the running direction of the web, as a result of which the bristles exert a corresponding normal force on the web without significantly impeding the running of the web.
- the at least one functional component can also produce an electrically conductive connection between the web of material and the at least one supporting body. This is particularly important in the case of electrostatically chargeable, insulating webs of material, since surface charges can be easily dissipated in this way. such Surface charges can impede further process steps to which the web is subjected or disrupt subsequent devices.
- the at least one functional component can also have at least one sliding surface for the web of material.
- This sliding surface prevents the edges of the slats from being pressed into the web, so that the web does not have to be smoothed again.
- sensitive fabrics such as natural silk, thin plastic foils or thin metal foils are protected in this way and the formation of dented slat edges is prevented.
- the sliding surface of the functional component is particularly advantageous when the process step following the roller requires a smooth web of material.
- this sliding surface can also be set at an angle to the running direction of the web of material, in order in this way to achieve a grazing effect on the web of material.
- the sliding surface if it is curved in the circumferential direction of the at least one support body.
- the sliding surface is flush and tangential to the two adjacent slats, so that no edges are formed on the surface of the roller that could be pressed into the web.
- the figure 1 shows a sectional view of a roller 1 for guiding or spreading a running web of material 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 of material 2.
- the roller 1 has a supporting body 3, which in Is essentially constructed cylindrical.
- the support body 3 is rotatably supported about an axis, not shown, the axis perpendicular to the plane according to figure 1 is aligned.
- receptacles 4 for slats 5 are provided on the outside, which are supported so as to be displaceable axially with respect to the support body 3 .
- the slats 5 are shown in one piece in the exemplary embodiments, they can also be made in several parts. In particular, consideration is given to designing the slats 5 as slat bodies with a covering applied thereto. This covering can then be optimized for the particular requirements of the web 2 in question. These slats 5 grasp the web 2 , with an axial movement of the slat 5 being transmitted to the web 2 .
- the web of material 2 can thus be guided, that is to say its position can be changed and/or it can be spread out, that is to say its width can be changed.
- the receptacles 4 are designed with undercuts in order to ensure that the slats 5 are held securely in the receptacles 4 .
- an undercut groove 6 is also provided between the slats 5 in the supporting body 3 . Since the space between the slats 5 is usually very small, the undercut groove 6 - viewed in the radial direction 8 - reaches partially under the slats 5. In this area, the support body 3 is designed with sufficiently thick walls so that the associated weakening of the Supporting body 3 plays no role.
- an undercut 9 is S-shaped. This shape also has the advantage that it fits into the supporting 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 supporting body 3 in this way.
- This foot 10 is preferably designed to be elastically deformable, in order in this way to ensure that the functional component sits without play 7 in the undercut groove 6 to ensure. This is particularly important in those applications in which the orientation of the functional component 7 is important.
- the figure 2 shows an alternative embodiment of the roller 1, with the same reference numbers denoting the same parts. Only the differences from the embodiment according to FIG figure 1 received.
- the undercut groove 6 is designed as a threaded drive channel 11, so that a functional component (not shown) can be screwed to the roller 1 very easily in this way. 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 intended to transmit axial forces to the running material web 2 .
- the functional component 7 is based on the illustrations according to the 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 direction of travel 21 of the web of material and in this way generate an outwardly directed force on the web of material 2 . These ribs 20 ensure, for example, that rolled-up web edges roll out or prevent the edges from rolling up again. For this purpose, the ribs 20 are arranged mirror-symmetrically to the illustrated ribs 20 in the region of the other opposite end, in order to roll out the left and right web edges accordingly.
- the figure 4 shows an alternative embodiment of the functional component 7.
- the ribs 20 are replaced by brushes 30.
- FIG. These brushes 30 can on the one hand exert a stripping effect and/or a fixing effect on the material web 2.
- a fixing effect is understood to be a measure that ensures that the material web 2 remains in the spread-out position.
- the brushes 30 are inclined in such a way that they are each inclined towards the nearest end of the roller. As a result, the stripping effect is increased accordingly.
- the brushes 30 could also be aligned in the radial direction, so that the brushes 30 only have a corresponding stripping effect due to their arrangement transversely to the running direction.
- 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 bordering on both sides.
- This sliding surface 40 prevents, for example, the emergence of depressed 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 material web 2 in addition to guiding. However, this division results in a gap over which the material 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 .
- the figure 6 shows a spatial representation of a further functional component 7.
- This functional component 7 has electrically conductive brushes 12, 13 which 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 material web 2 or the slat 5. which could lead to electrical flashovers or impairment of the function of subsequent electrical assemblies.
- Such a measure is only expedient in the case of electrically insulating webs of material 2, especially since even slightly conductive webs of material 2 do not exhibit any electrical charging phenomena.
- the electrically conductive brushes 12 touch the web 2 directly, while the electrically conductive brushes 13 only establish an electrical connection with the slats 5 .
- the brushes 12 or 13 can also be omitted.
- the figure 7 shows a spatial 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.
- the figure 8 shows a spatial representation of another 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 radially considerably over the slats 5. In this way, unwanted forces are reliably prevented from acting on the slats 5 during transport of the roller 1 .
- This functional component 7 must be dismantled for operation.
- the figure 9 shows a spatial representation of a further functional component 7 with a cleaning function.
- this functional component 7 has bristles 60 which are aligned approximately in the circumferential direction of the roller 1 and which clean the slats 5 during their axial movement.
- the bristles 60 can be provided with a physical or chemical cleaning agent. In the Usually, however, the mechanical action of the bristles is completely sufficient to clean the slats 5.

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 supporting body. On the outside of this supporting body, there are receptacles for axially displaceable slats that grasp the web.
Aus der
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 outset, 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 serves to guide and/or spread a running web of material. Guiding is to be understood as meaning the change in position of the web of material transversely to its running direction, with the width of the web of material remaining essentially unchanged. By spreading, on the other hand, one understands the stretching of the web of material transversely to its direction of travel, with the position of the center of the web of material remaining essentially unchanged. Of course, leading and spreading can also be done in combination, i.e. at the same time. The roller has at least one supporting body, which is preferably held so as to be rotatable about an axis. On the support body, receptacles for slats are provided on the outside, on which slats are held in an axially displaceable manner. These slats can grasp the material web on the outside directly or indirectly. To increase the functionality of the roller, at least one undercut groove is formed on at least one support body between two of the slats, which 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 supporting body. The at least one functional component can easily reach between two slats due to the selected position of the at least one groove and thus reach the 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.It is particularly advantageous when space is limited 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—seen in the radial direction—so that the at least one functional component is held sufficiently securely 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. The at least one functional component can thus be simply screwed to the roller. A thread drive channel also has the advantage that at least one screw can be screwed in at any desired point along the at least one undercut groove, without the need for 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.In order 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 accommodation of the slats on the one hand and the at least one groove for accommodating the functional component on the other hand can be optimally utilized. 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.In order for the at least one functional component to be able to exert a stripping effect on the web of material, it is advantageous if it has ribs which are set at an acute angle to a direction of travel of the web of material and grip the web of material. This results in an advantageous stripping device which, in particular, rolls out edges of the material web and prevents it from rolling up 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 at least one brush can also grasp the 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.A wiping effect results in particular from the obliquely arranged rows of bristles of the at least one brush. Here they can Rows of bristles may be arranged obliquely in the axial direction or similar to the ribs mentioned above. The at least one brush presses against the web of material and causes a frictional force that is dependent on the speed of the web of material. As a result of the obliquely arranged rows of bristles, this frictional force, which is originally directed in the running direction of the web, is divided into a component in the direction of the rows of bristles and a component transverse thereto. This creates a force directed away from the center of the material web, which can smooth rolled edges, for example. Alternatively or additionally, the bristles themselves can be aligned at an acute angle to the radial direction of the roller. This also creates a force that is aligned transversely to the running direction 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.Alternatively or additionally, the rows of bristles of the at least one brush can also be arranged in such a way that there is a fixing effect. This means that the action of the at least one brush prevents the material web from contracting back to its original width after leaving the roller. In order to achieve a fixing effect, a row of bristles oriented obliquely outwards is not required. However, the bristles are preferably arranged in such a way that they enclose an obtuse angle with the vector of the running direction of the web, as a result of which the bristles exert a corresponding normal force on the web without significantly impeding 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 web of material and the at least one supporting body. This is particularly important in the case of electrostatically chargeable, insulating webs of material, since surface charges can be easily dissipated in this way. such Surface charges can impede further process steps to which the web is subjected or disrupt subsequent 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 web of material. This sliding surface prevents the edges of the slats from being pressed into the web, so that the web does not have to be smoothed again. In particular, sensitive fabrics such as natural silk, thin plastic foils or thin metal foils are protected in this way and the formation of dented slat 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.The sliding surface of the functional component is particularly advantageous when the process step following the roller requires a smooth web of material. As an alternative or in addition, this sliding surface can also be set at an angle to the running direction of the web of material, in order in this way to achieve a grazing effect on the web of material.
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 advantageous for the sliding surface if it is curved in the circumferential direction of the at least one support body. Preferably, the sliding surface is flush and tangential to the two adjacent slats, so that no edges are formed on the surface of the roller that could be pressed into the web.
Selbstverständlich können die oben beschriebenen Ausbildungen der Funktionsbauteile auch in beliebiger Weise kombiniert werden, um mehrere Funktionen gleichzeitig zu erfüllen.Of course, the configurations of the functional components described above 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 of the invention is explained by way of example with reference to the drawing, without restricting the scope of protection.

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
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.Also provided between the
