Abstract
Description
Die Erfindung betrifft ein Papiermaschinenband, das als Gliederband insbesondere für Papiermaschinen mit sich in Querrichtung erstreckenden Scharnierdrähten und mit sich in Längsrichtung erstreckenden, jeweils wenigstens zwei benachbarte Scharnierdrähte umschließenden Gliederelementen ausgebildet ist, wobei Gliederelemente über die Breite des Gliederbands in Längsrichtung um wenigstens einen Scharnierdraht versetzt sind.The invention relates to a paper machine belt, which as Link belt in particular for paper machines Hinge wires extending transversely and with themselves extending in the longitudinal direction, at least two each adjacent hinge wires surrounding link elements is formed, link elements across the width the link belt in the longitudinal direction by at least one Hinge wire are offset.
Ein solches Papiermaschinenband ist in der US-A-4 469 221 offenbart. Es hat eine Vielzahl von in Querrichtung verlaufenden, im Querschnitt kreisrunden Scharnierdrähten, die über Gliederelemente verbunden sind. Es sind eine Vielzahl von unterschiedlich geformten Gliederelementen gezeigt, die sämtlich an ihren Enden Durchgangsöffnungen für die Aufnahme von jeweils zwei benachbarten Scharnierdrähten aufweisen. Die Durchgangsöffnungen sind geschlitzt, damit die Durchgangsöffnungen aufgeweitet werden können. Dies ermöglicht es, die Gliederelemente mit den Scharnierdrähten durch eine Bewegung senkrecht zu deren Längsachsen einschnappen zu lassen. Es können deshalb auch einzelne Gliederelemente innerhalb eines gesamten Gliederbands ausgewechselt werden.Such a paper machine belt is in US-A-4,469,221 disclosed. It has a variety of transverse, hinge wires circular in cross section, which are connected by link elements. They are one Variety of differently shaped link elements shown all through openings at their ends for holding two adjacent hinge wires exhibit. The through openings are slotted, so that the through openings are widened can. This allows using the link elements by moving the hinge wires perpendicular to to snap their longitudinal axes. It can therefore even individual link elements within an entire Link bands to be replaced.
Bei diesem Papiermaschinenband kann wegen der geschlitzten Durchgangsöffnungen nur eine begrenzte Stabilität in Zugrichtung erreicht werden. Es besteht die Gefahr des Aufweitens der Durchgangsöffnungen und des Brechens der die Durchgangsöffnungen begrenzenden Bögen der Gliederelemente.This paper machine belt can because of the slotted Through holes have limited stability in Train direction can be reached. There is a risk of Widening the through openings and breaking the the arches delimiting the through openings of the link elements.
Dies kann sich wie ein Riß fortsetzen, so daß schon die Beschädigung einzelner Gliederelemente zum völligen Bruch des Gliederbands führen kann. Weiterhin ist von Nachteil, daß sich die Luftdurchlässigkeit nicht wesentlich beeinflussen läßt. Die Luftdurchlässigkeit ist aber gerade in dem Bereich, in dem ein Gliederband hauptsächlich zur Anwendung kommt, nämlich in der Trockenpartie einer Papiermaschine, eine wesentliche Eigenschaft und muß sich deshalb auf einen optimalen Wert einstellen lassen.This can continue like a crack, so that the Damage to individual link elements to complete breakage of the link belt. Another disadvantage is that the air permeability is not significantly affected leaves. The air permeability is just in the area where a link belt is mainly used comes, namely in the dryer section of a paper machine, an essential property and must therefore have it set to an optimal value.
Daneben sind sogenannte Drahtgliederbänder bekannt, wie sie sich beispielsweise aus den US-A-4 395 308, EP-A-0 050 374, EP-A-0 128 496, EP-B-0 292 700, EP-A-0 112 432, EP-A-0 472 072, EP-A 0 171 891, EP-B-0 211 471 und DE-A-24 19 751 ergeben. Solche Drahtgliederbänder haben ebenfalls eine Vielzahl von sich in Querrichtung erstreckenden Scharnierdrähten, wobei die Scharnierdrähte nicht nur kreisrunden, sondern auch flach ovale oder rechteckige oder knochenförmige Querschnitte haben können. Die Scharnierdrähte werden bei Drahtgliederbändern durch Drahtwendeln miteinander verbunden, die jeweils zwei benachbarte Scharnierdrähte umfassen und sich in Richtung der Scharnierdrähte wendelförmig fortschreitend erstrecken. Dabei kämmen sie mit jeweils benachbarten Drahtwendeln.In addition, so-called wire link belts are known, such as they can be found, for example, in US Pat. No. 4,395,308, EP-A-0 050 374, EP-A-0 128 496, EP-B-0 292 700, EP-A-0 112 432, EP-A-0 472 072, EP-A 0 171 891, EP-B-0 211 471 and DE-A-24 19 751. Such wire link belts also have a multitude of them in the transverse direction extending hinge wires, the hinge wires not only circular, but also flat oval or can have rectangular or bone-shaped cross sections. The hinge wires are used in wire link belts connected by wire spirals, each embrace two adjacent hinge wires and in Direction of the hinge wires progressing helically extend. They comb with neighboring ones Wire helices.
Bei diesen Drahtgliederbändern besteht zwar die Möglichkeit, zwischen jeweils zwei Scharnierdrähte in den von den Drahtwendeln umgebenen Raum Füllelemente einzubauen, um hierdurch die im allgemeinen zu große Luftdurchlässigkeit gezielt herabzusetzen (vgl. EP-A-0 050 374, EP-B-0 292 700, EP-A-0 128 496, DE-A-24 19 751). Nachteilig ist jedoch bei Drahtgliederbändern, daß die Herstellung nicht einfach ist. Die Fertigung der Drahtwendeln erfolgt durch plastische Verformung unter Hitzeeinfluß, so daß hierfür nur Thermoplaste verwendet werden können. Außerdem müssen links- und rechtsgewendelte Drahtwendeln bereitgehalten sowie in der richtigen Ordnung und miteinander kämmend verbunden werden. Ferner ist nachteilig, daß die Beschädigung iner Drahtwendel den Riß des gesamten Drahtgliederbands zur Folge haben kann.With these wire link belts there is the possibility between two hinge wires in each of the to install filling elements in the space surrounding the wire helices, in order to make the air permeability generally too great targeted reduction (cf. EP-A-0 050 374, EP-B-0 292 700, EP-A-0 128 496, DE-A-24 19 751). Disadvantageous However, in the case of wire link belts, that is the manufacture is not easy. The wire helices are manufactured by plastic deformation under the influence of heat, so that only thermoplastics can be used for this. Furthermore must have left and right hand helices kept ready and in the right order and with each other combing be connected. It is also disadvantageous that the damage in the wire coil caused the crack of the whole Wire link belt can result.
In der DE-A-1 950 302 ist ein Transportband für die Herstellung von Schwämmen oder Schwammtüchern beschrieben, das als Geflecht ausgebildet ist, das aus weitgehend formstabilen Querstäben und aus Wendeln oder Einzelkettengliedern besteht, die einander überlappend die Querstäbe schlaufenartig und flexibel verbinden. Damit soll eine schnellere und gleichmäßigere Koagulation der auf das Transportband aufgebrachten Viskosemasse erzielt werden.DE-A-1 950 302 describes a conveyor belt for production described by sponges or sponge cloths, which is designed as a mesh that largely consists of dimensionally stable cross bars and made of spirals or single chain links consists of the cross bars overlapping each other Connect in a loop-like and flexible manner. With that faster and more even coagulation of the the viscose mass applied to the conveyor belt can be achieved.
Der Erfindung liegt die Aufgabe zugrunde, ein Papiermaschinenband der eingangs genannten Art so zu gestalten, daß es besonders zugfest ist, daß die Luftdurchlässigkeit eingestellt werden kann und daß es sich auf einfache Weise unter Verwendung auch nicht thermoplastischer Werkstoffe herstellen läßt.The invention has for its object a paper machine belt of the type mentioned at the beginning that it is particularly tensile that the air permeability can be adjusted and that it is simple using non-thermoplastic materials can be made.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Gliederelemente als Ringelemente mit jeweils einer einzigen Ringöffnung ausgebildet sind, die wenigstens zwei benachbarte Scharnierdrähte umschließt.This object is achieved in that the link elements as ring elements with one each single ring opening are formed, at least encloses two adjacent hinge wires.
Grundgedanke der Erfindung ist es, als Gliederelemente Ringelemente zu verwenden, die auf die Scharnierdrähte hintereinander aufgeschoben werden und jeweils zumindest zwei benachbarte Scharnierdrähte umschließen. Im Vergleich zu den Gliederelementen der gattungsgemäßen Papiermaschinenbänder und den Drahtwendeln von Drahtgliederbändern haben die erfindungsgemäßen Ringelemente eine hohe Stabilität insbesondere in Zugrichtung des Gliederbands. Die Beschädigung eines der Gliederelemente ist unkritisch, da sich die Beschädigung nicht fortsetzen kann. Die Ringöffnungen der Ringelemente eröffnen zudem die Möglichkeit, Füllelemente aufzunehmen, um hierdurch die Luftdurchlässigkeit des Papiermaschinenbandes auf einen gewünschten Wert einzustellen. Hinzu kommt, daß sich solche Papiermaschinenbänder auf sehr einfache Weise herstellen lassen und daß man für die Teile des Papiermaschinenbandes nicht auf bestimmte Materialien festgelegt ist. So besteht die Möglichkeit, auch Duromere einzusetzen, wobei die Ringelemente durch Ausstanzen aus einem Band oder Abschneiden von entsprechend geformten Rohren gefertigt werden können. Auf diese Weise können hochfeste Papiermaschinenbänder zu relativ geringen Kosten bereitgestellt werden.The basic idea of the invention is as link elements Use ring elements on the hinge wires be pushed one behind the other and at least in each case enclose two adjacent hinge wires. Compared to the link elements of the generic Paper machine tapes and the wire coils of wire link tapes have the ring elements of the invention high stability, especially in the direction of tension of the link belt. The damage to one of the link elements is not critical, because the damage cannot continue. The ring openings of the ring elements also open the Possibility to include filler elements to thereby Air permeability of the paper machine belt on one set the desired value. In addition, there are such Making paper machine tapes in a very simple way leave and that one for the parts of the paper machine belt not limited to certain materials is. So it is possible to use thermosets, wherein the ring elements by punching out a Strip or cut appropriately shaped pipes can be manufactured. In this way, high strength Paper machine tapes at a relatively low cost to be provided.
In Ausbildung der Erfindung ist vorgesehen, daß die Höhe der Ringöffnungen über ihre Erstreckung in Längsrichtung gleichbleibend ist, wobei die Höhe der Ringöffnungen der er Scharnierdrähte entsprechen sollte. Es sind jedoch auch andere Formgebungen von Ringöffnungen denkbar.In an embodiment of the invention it is provided that the height of the ring openings over their extension in the longitudinal direction is constant, the height of the ring openings it should match hinge wires. However, there are other shapes of ring openings are also conceivable.
Desweiteren ist vorgeschlagen, daß die Ringelemente oben- und/oder untenseitig eine gerade, vorzugsweise plane Oberfläche haben. Abweichend davon besteht die Möglichkeit, die Oberflächen auch konvex oder konkav auszubilden, um eine bessere Anpassung an die jeweiligen Verhältnisse zu erzielen.Furthermore, it is proposed that the ring elements above and / or on the underside a straight, preferably plane Have surface. Deviating from this, there is the possibility make the surfaces convex or concave, to better adapt to the respective conditions to achieve.
Grundsätzlich kommen alle möglichen Querschnitte für die Ringelemente in Frage, beispielsweise runde oder ovale Querschnitte. Es kann jedoch zweckmäßig sein, den Ringelementen einen quadratischen oder rechteckigen Querschnitt zu geben, insbesondere wenn eine plane Oberfläche gewünscht ist. Basically all possible cross sections come for that Ring elements in question, for example round or oval Cross sections. However, it may be appropriate to use the ring elements a square or rectangular cross section to give, especially if a flat surface is desired.
Die Scharnierdrähte können in an sich bekannter Weise kreisrunden Querschnitt haben. Bei dieser Querschnittsform ist die Scharnierfähigkeit und damit die Umlenkbarkeit des Gliederbands besonders ausgeprägt. Es besteht jedoch auch die Möglichkeit, die Scharnierdrähte oval oder als Flachdrähte (vgl. US-A-4 395 308) auszubilden, wobei sich deren Flachseiten parallel zur Bandebene erstrecken. Solche Scharnierdrähte verbessern die Zugfestigkeit des Gliederbands bzw. bei gleicher Zugfestigkeit lassen sich besonders flache Gliederbänder herstellen. Durch Einstellung des Höhe-Breite-Verhältnisses kann auch die Luftdurchlässigkeit in gewünschter Weise beeinflußt werden. Es empfiehlt sich, daß die Scharnierdrähte unabhängig von ihrem Querschnitt stirnseitig gerundet sind, um die Scharnierfunktion zu unterstützen.The hinge wires can be made in a manner known per se have a circular cross-section. With this cross-sectional shape is the hinge ability and thus the deflectability of the link band is particularly pronounced. It exists however, the possibility of making the hinge wires oval or as flat wires (cf. US-A-4 395 308), with their flat sides parallel to the band plane extend. Such hinge wires improve tensile strength of the link belt or with the same tensile strength particularly flat link belts can be produced. By adjusting the height-width ratio also influences the air permeability in the desired manner become. It is recommended that the hinge wires regardless of their cross-section rounded on the front are to support the hinge function.
Auch bei diesem Gliederband kann vorgesehen sein, daß die Abstützung der Ringelemente an den Scharnierdrähten derart ausgebildet ist, daß die Ringelemente um Scharnierachsen verschwenken, die gegenüber der Mittelebene des Gliederbands zu einer der Flachseiten hin verschoben sind. Diese bei Drahtgliederbändern bekannte Ausbildung (EP-B-0 472 072, auf die vollinhaltlich Bezug genommen wird) hat den Vorzug, daß die tatsächliche Scharnierachse in Richtung auf die Kontaktfläche zwischen der zu transportierenden Bahn und dem Gliederband verlagert und dadurch die Relativbewegung zwischen dem Gliederband und der Bahn beim verschwenken der Ringelemente verringert wird. Also in this link belt it can be provided that the Support the ring elements on the hinge wires in such a way is formed that the ring elements around hinge axes swivel that towards the median plane of the Link bands are shifted towards one of the flat sides. This with wire link belts known training (EP-B-0 472 072, on the full reference) has the advantage that the actual hinge axis towards the contact surface between the train to be transported and the Link belt shifted and thus the relative movement between the link belt and the web when swiveling the ring elements is reduced.
Ferner ist gemäß der Erfindung vorgesehen, daß die jeweils benachbarten Ringelemente um einen Scharnierdraht in Längsrichtung des Bandes zueinander versetzt sind. Auf diese Weise ergibt sich eine besonders gleichmäßige Struktur des Gliederbands.It is further provided according to the invention that each adjacent ring elements around a hinge wire are offset from one another in the longitudinal direction of the belt. In this way there is one particularly even structure of the link belt.
In weiterer Ausgestaltung der Erfindung ist vorgeschlagen, daß die Ringelemente an einer oder beiden Flachseiten des Gliederbands verbreiterte Abschnitte aufweisen, wobei sich die Abschnitte vorzugsweise in Längsrichtung bis nahe an die von dem jeweils zugehörigen Ringelement umschlossenen Scharnierdraht erstrecken. Solche verbreiterten Abschnitte sind bei Drahtgliederbändern aus der EP-A-0 112 432, EP-A-0 171 891 und EP-B 0 211 471 bekannt. Mit Hilfe dieser verbreiterten Abschnitte läßt sich die Luftdurchlässigkeit des Gliederbands auf ein gewünschtes Maß einstellen, was insbesondere für die Verwendung vom Trockenbereich einer Papiermaschine nützlich ist. Außerdem wird hierdurch die Abstützfläche für die Papierbahn vergrößert, und zwar insbesondere dann, wenn die Abschnitte von in Querrichtung benachbarten Ringelementen so breit sind, daß sie im Bereich der Abschnitte eine im wesentlichen geschlossene Oberfläche bilden.In a further embodiment of the invention, it is proposed that that the ring elements on one or both flat sides of the link belt have widened sections, the sections preferably extending in the longitudinal direction to close to that of the associated ring element extend enclosed hinge wire. Such widened Sections are made of wire link belts EP-A-0 112 432, EP-A-0 171 891 and EP-B 0 211 471 known. With the help of these widened sections lets the air permeability of the link belt to a desired one Set size, which is especially for use from the dry area of a paper machine is. This also makes the support surface for the Paper web enlarged, especially when the sections of adjacent ring elements in the transverse direction are so wide that they are in the area of the sections form a substantially closed surface.
Das erfindungsgemäße Papiermaschinenband kann zusätzlich auf wenigstens einer der Flachseiten eine Schicht aufweisen, beispielsweise eine Faserschicht, ein Gewebe, ein Gewirke, ein Gelege und/oder eine Folie, wie dies bei Drahtgliederbändern insbesondere in Kombination mit den oben beschriebenen verbreiterten Abschnitten bekannt ist (vgl. EP-A-⊘ 171 891, EP-B-⊘ 211 471). Auf diese Weise kann die Oberflächenbeschaffenheit des Gliederbands entsprechend den jeweiligen Anforderungen angepaßt werden. Dabei kommt auch eine Kombination solcher Schichten, beispielsweise ein Gewebe oder ein Gewirke mit aufgenadelter Faserschicht, in Frage.The paper machine belt according to the invention can additionally have a layer on at least one of the flat sides, for example a fiber layer, a fabric Knitted fabrics, a Scrims and / or a film, as is the case with wire link belts especially in combination with those described above widened sections is known (cf. EP-A-⊘ 171 891, EP-B-⊘ 211 471). In this way, the Surface quality of the link belt according to the be adapted to the respective requirements. It also comes a combination of such layers, for example a fabric or a knitted fabric with a needled layer of fibers, in question.
Nach der Erfindung ist ferner vorgesehen, daß die Scharnierdrähte aus einem oder mehreren, in einer Ummantelung eingelagerten Monofilamenten, Multifilamenten und/oder Zwirnen gebildet sind, wie dies gleichfalls schon bei Drahtgliederbändern vorgeschlagen worden ist (vgl. EP-B-⊘ 292 7⊘⊘, auf die vollinhaltlich Bezug genommen wird).According to the invention it is further provided that the Hinge wires made of one or more, in one sheath embedded monofilaments, multifilaments and / or twists are formed, as is already the case with Wire link belts has been proposed (cf. EP-B-⊘ 292 7⊘⊘, to which full reference is made).
Die Ringelemente können aus Vollkunststoff bestehen, wobei der verwendete Kunststoff an die jeweiligen Anforderungen entsprechend seinen Eigenschaften angepaßt werden kann. Bei höheren Anforderungen insbesondere an die mechanische Festigkeit kommen auch Ringelemente in Frage, die aus einem mit einer Armierung versehenen Kunststoff bestehen. Die Armierung kann aus Fasern, Fäden, Gewirken, Geweben und/oder Fadengelegen bestehen.The ring elements can be made of all-plastic, the used plastic according to the respective requirements can be adapted to its properties. At higher Mechanical strength requirements in particular ring elements are also possible, which consist of one with one Reinforced plastic exist. The reinforcement can from fibers, threads, knitted fabrics, woven fabrics and / or thread beds consist.
In der einfachsten Ausführung umschließen die Ringelemente jeweils zwei benachbarte Scharnierdrähte. Es besteht jedoch auch die Möglichkeit, daß die Ringelemente drei oder mehr aufeinanderfolgende Scharnierdrähte einschließen, wobei durch entsprechende Versetzung der Ringelemente der Abstand der Scharnierdrähte auch bei dieser Ausführungsform gleichgehalten werden kann.In the simplest version, the ring elements enclose each two adjacent hinge wires. However, it also exists the possibility that the ring elements three or more consecutive Include hinge wires, with appropriate ones Displacement of the ring elements the distance of the hinge wires also be kept the same in this embodiment can.
In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispiels näher veranschaulicht. Es zeigen:
- Figur 1
- einen Ausschnitt eines ersten erfindungsgemäßen Gliederbands in perspektivischer
Figur 2- einen Ausschnitt eines zweiten erfindungsgemäßen Gliederbands in perspektivischer
- Figure 1
- a section of a first link belt according to the invention in perspective
- Figure 2
- a section of a second link belt according to the invention in perspective
Bei dem in Figur 1 dargestellten Gliederband wird die Längserstreckung und damit auch die vorgesehene Laufrichtung des Gliederbands 1 durch den Doppelpfeil A symbolisiert wird. In dieser Richtung bildet das Gliederband 1 ein geschlossenes Endlosband.In the link belt shown in Figure 1, the longitudinal extent and thus also the intended running direction of the link belt 1 is symbolized by the double arrow A. In this direction, the link belt 1 forms a closed Endless belt.
Das Gliederband 1 hat eine Vielzahl von sich in Querrichtung
erstreckenden Scharnierdrähten, die beispielhaft mit 2
bezeichnet sind. Die Scharnierdrähte haben einen abgeflachten
Querschnitt großer Breite und demgegenüber geringer Höhe mit
einem Breite-Höhe-Verhältnis
von etwa 5:1. Die Scharnierdrähte 2 sind oben-
und untenseitig eben und an den in Laufrichtung gesehen vorderen
und hinteren Seiten halbkreisförmig gerundet. Sie haben jeweils
gleichen Abstand zueinander.The link belt 1 has a plurality of itself in the transverse direction
extending hinge wires, the example with 2
are designated. The hinge wires have a flattened one
Cross section of large width and, in contrast, low height
a width-height ratio
of about 5: 1. The
Jeweils zwei benachbarte Scharnierdrähte 2 werden von einem
Ringelement - beispielhaft mit 3 bezeichnet - gemeinsam in
einer einzigen Öffnung - beispielhaft mit 4 bezeichnet - umschlossen.
Die Ringelemente 3 sind an die Formgebung der Scharnierdrähte
2 in der Weise angepaßt, daß die Ringöffnungen 4
oval ausgebildet und durchgehend eine Höhe haben, die der Höhe
der Scharnierdrähte 2 entspricht. An den in Laufrichtung gesehen
vorderen und hinteren Kanten sind die Ringelemente 3 halbkreisförmig
in Anpassung an die Rundungen der Scharnierdrähte
2 gebogen. Two
Die Ringelemente 3 haben bei dieser Ausführungsform einen quadratischen
Querschnitt und verlaufen oben- und untenseitig gerade
gestreckt. Auf diese Weise werden plane Oberflächen - beispielhaft
mit 5 bezeichnet - gebildet.The
Jeweils zwei benachbarte Ringelemente 3 sind um einen
Scharnierdraht 2 in Längsrichtung versetzt zueinander
angeordnet. Dies bedeutet, daß ein erstes Ringelement 3 zwei
bestimmte Scharnierdrähte 2 umschließt, während die beiden
benachbarten Ringelemente 3 dergestalt versetzt sind, daß das
eine Ringelement von den beiden vorgenannten Scharnierdrähten
2 nur den einen und zusätzlich den in Längsrichtung folgenden
Scharnierdraht 2 umschließt, während das andere, in
Längsrichtung dahinterliegende Ringelement 3 von den beiden
vorgenannten Scharnierdrähten 2 nur den anderen und zusätzlich
den auf der anderen Seite benachbarten Scharnierdraht 2
umschließt. Dieses Muster setzt sich in stetiger Folge fort,
so daß zwei benachbarte Scharnierdrähte 2 in Querrichtung des
Gliederbands 1 gesehen nur von jedem zweiten Ringelement 3
gemeinsam umschlossen werden.Each two
Die Ringelemente 3 lassen sich in dem vorbeschriebenen Muster
auf einfache Weise auf die Scharnierdrähte 2 aufschieben. Dieser
Prozeß kann auch mechanisiert werden, so daß sich auf einfache
und schnelle Weise große Gliederbänder 1 herstellen lassen,
wie sie beispielsweise in der Trockenpartie von Papiermaschinen
benötigt werden. Dabei schließen die Ringelemente 3
zwischen den Scharnierdrähten 2 sich in Querrichtung über die
gesamte Breite des Gliederbands 1 erstreckende Kanäle 6 ein,
in die Füllelemente, wie sie sich aus der EP-A-⊘ ⊘5⊘ 374 oder
der EP-A-⊘ 128 496 ergeben, eingesetzt werden können. Auf
diese Weise läßt sich die Luftdurchlässigkeit des Gliederbands
auf einen gewünschten Wert herabsetzen.The
Das in Figur 2 dargestellte Gliederband 11, dessen
Laufrichtung durch den Doppelpfeil B symbolisiert wird, hat
ebenfalls eine Vielzahl von sich in Querrichtung erstreckenden
Scharnierdrähten, die beispielhaft mit 12 bezeichnet sind und
in diesem Fall kreisrunden Querschnitt haben. Jeweils zwei
benachbarte Scharnierdrähte 12 werden von einem Ringelement -
beispielhaft mit 13 bezeichnet - umschlossen. Die Ringelemente
13 sind so ausgebildet, daß eine ovale Ringöffnung 14 gebildet
wird, welche durchgehend die gleiche Höhe hat, wobei die Höhe
dem Durchmesser der Scharnierdrähte 12 entspricht. An den in
Laufrichtung gesehen vorderen und hinteren Enden sind die
Ringelemente 13 halbkreisförmig in Anpassung an die
Scharnierdrähte 12 gebogen.The
Die Ringelemente 13 haben rechteckigen Querschnitt und
verlaufen oben- und untenseitig gerade gestreckt. In diesen
gerade gestreckten Bereichen weisen die Ringelemente 13 oben-
und untenseitig zu beiden Querseiten vorspringende,
verbreiterte Abschnitte - beispielhaft mit 15 und 16
bezeichnet - auf, wobei sich die Abschnitte 15, 16 von in
Querrichtung benachbarten Ringelementen 13 praktisch
aneinander anlegen, so daß in dem Bereich dieser Abschnitte
15, 16 eine fast geschlossene Oberfläche entsteht.The
Im übrigen stimmt die Anordnung der Ringelemente 13 zueinander
mit der gemäß der Ausführungsform in Figur 1 überein, d. h. im
Bereich der Scharnierdrähte 12 wechselt sich jeweils ein
erstes Ringelement 13, das zwei bestimmte Scharnierdrähte 12 umschließt,
mit einem danebenliegenden Ringelement 13 ab,
welches in Längsrichtung (Pfeil B) um einen Scharnierdraht 12
versetzt ist. Auf diese Weise werden zwei benachbarte
Scharnierdrähte 12 in Querrichtung des Gliederbands 11 gesehen
nur von jedem zweiten Ringelement 13 gemeinsam umschlossen.Otherwise, the arrangement of the
Auch bei diesem Gliederband 11 werden sich in Querrichtung
über die gesamte Breite erstreckende Kanäle 17 gebildet.
Selbstverständlich steht es frei, auch in diese Kanäle 17
Füllelemente, wie sie beispielsweise aus der EP-A-⊘ ⊘5⊘ 374,
EP-A-⊘ 128 496, DE-A-24 19 751 und EP-B-⊘ 292 7⊘⊘ bekannt,
einzusetzen. Im Regelfall kann jedoch wegen des Vorhandenseins
der Abschnitte 15, 16 bei dieser Ausführungsform auf solche
Füllelemente verzichtet werden.This
