- comparatively thin threads can be used, which by grouping together nevertheless act as "thicker threads", which then together with the threads of the second fabric layer extending in the other direction which, in fact, can have a larger cross-sectional dimension without creating the disadvantages of using generally very coarse, thick-filament fabric structures to produce a very stable, stable machine contact surface.
- adjacent groups of unidirectionally extending filaments of the second fabric layer comprise the same number of filaments in the other direction.
- the interaction of the pairs of binder yarns with the unidirectional yarns of the second fabric layer may be such that a binder yarn pair alternately has a binder yarn on the machine contact side of a group of yarns of the second fabric layer extending in one direction and the other binder yarn the machine contact page of the next but one group of in the extending one direction extending threads of the second fabric layer.
- two threads of the first fabric layer extending in the other direction and two threads of the second fabric layer extending in the other direction are provided between two binding thread pairs succeeding one another.
- the number of existing threads of the first fabric layer or the second fabric layer can be chosen differently, which depends on how strong the mutual connection of the two fabric layers should be.

- the offsets formed at the attachment points not only of the threads extending in the other direction but also of the threads extending in one direction, in particular those threads extending in the other direction are loaded against each other between two in one direction Distance from each other arranged Abbindestellen, ie in particular the third and fourth Abbindestelle, are positioned.
- the threads of the second thread extending in the other direction form between the threads forming the first bonding zone and the second bonding zone Fabric layer is arranged a binder thread pair.
- the binding threads of a respective pair of binding threads are tightly bordered and thus also supported by those threads, which are combined by two or more tie-down points to in the other direction extending and then in one direction then adjacent groups.
- the second fabric layer ie the fabric layer which also makes contact with the various deflecting or driving rollers, can for example be constructed such that in a repeat field each thread of the second fabric layer extending in the other direction adjoins a single one direction extending thread of the second fabric layer for forming a Abbindestelle sets, and / or that in a repeat field at each in one direction extending thread of the second fabric layer, a single in the other direction extending thread of the second fabric layer sets.
- the one direction may, for example, correspond to the band longitudinal direction, in which case the other direction corresponds to the band transverse direction.
- the one direction corresponds to a warp direction and the other direction corresponds to a weft direction.
- Fig. 1 to 3 is based on the course of the various threads of two layers of fabric, for example, usable as a forming fabric fabric tape, the binding principle of the present invention explained.
- B1, B2, B3, B4, B5, B6, B7 and B8 denote those threads of a machine-side fabric layer 100, which in the Fig. 1 and 3 yourself extend from left to right and extend in the fabric tape preferably in a tape transverse direction CMD.
- T1, T2, T3, T4, T5, T6, T7 and T8 denote the filaments of a web material-side fabric layer 102 which extend in the same direction, that is to say the tape transverse direction CMD.
- 100 threads 2, 4, 6, 8, 10, 12, 14, 16 extend in the machine side fabric layer, which band longitudinal direction MD also corresponds to a machine direction, while equally in the web material side fabric layer 102 threads 1, 3, 5 , 7, 9, 11, 13 and 15 extend in the tape longitudinal direction MD.

- BI8 That is, within each repeat field, several such binder thread pairs Bi1-2, Bi3-4, Bi5-6, Bi7-8 exist consecutively in the band longitudinal direction MD.
- the individual binding threads change, as illustrated, for example, by means of the pair of binding threads Bi1-2, at intersections K between the web material-side fabric layer 102 and the machine-side fabric layer 104.
- binding threads Bi1 and Bi2 are integrated into the web material-side fabric layer 102, together with the filaments 1, 3, 5, 7, 9, 11, 13, 15 extending in the band longitudinal direction MD, form a plain weave, so that a very finely structured web material contact surface is formed on the web material side 106.
- the binding threads Bi1, Bi2, Bi3, Bi4, Bi5, Bi6, Bi7, Bi8 are thus also structurally forming are used, so that each binder thread pair Bi1-2, Bi3-4, Bi5-6, Bi7-8 in the web material-side fabric layer 104 actually replaces a complete and in the tape transverse direction CMD extending thread.
- the yarns B1, B2, B3, B4, B5, B6, B7 and B8 extending in the tape transverse direction CMD generally run on a side of the corresponding yarns 2, 4, 6 extending in the tape longitudinal direction MD on a machine side 108 8, 10, 12, 14, 16 of this fabric layer 100.
- each of the yarns B1-B8 extending in the transverse tape direction CMD binds at a bonding point X via one of the yarns 2, 4, 6, 8, 10, 12 , 14, 16 of this fabric layer 100 from.
- the term "over” here means that the setting takes place on the side facing away from the machine side 108 of a respective extending in the tape longitudinal direction MD thread, as for example, the Abbindestelle X of the thread B1 in Fig. 3 is illustrated. Where these threads B1-B8 form no tie-off points X, they run or float on the machine side 108 of the threads 2, 4, 6, 8, 10, 12, 14, 16 of this fabric layer 100 extending in the tape longitudinal direction MD.
- an atlas binding in the illustrated example of a repeat field with eight adjacent threads Achteratlas Kunststoff realized, which ensures that almost the entire machine contact surface is provided on the machine side 108 by evenly extending thread sections, so that on the one hand produces a very smooth, flat machine contact surface On the other hand, thereby the wear resistance is increased.
- binder thread pair Bi3-4 equally summarized with the binder thread Bi3 the threads 8, 10 to a group G1, while the binder thread Bi4 summarizes the thread 2 of this repeat field with the thread 16 of an immediately adjacent repeat field to a group G1.
- binder thread pair Bi5-6 again summarizes the threads 4, 6 and 12, 14 together to form a respective group G1.
- Fig. 1 recognizable structure in which by a respective binder thread pair Bi1-2, Bi3-4, Bi5-6, Bi7-8 groups G1 of extending in the band longitudinal direction MD threads are summarized in that a respective one of the binding threads on the machine side 108 of these threads or group G1 of threads.
- each binding thread pair for example the binding thread pair Bi1-2
- each binding thread pair Bi1-2 is then each a group of threads extending in the band longitudinal direction, which are not combined by this binding thread pair in that a respective binding thread extends on the machine side of these threads.
- the binding thread pair Bi1-2 these are in Fig. 3
- groups G1 in the band longitudinal direction MD extending threads, which are formed here by the threads 4, 6 and 8, 10 and 12, 14 and 16, 2 (in the adjoining region of two repeat fields). These groups G1 extend through the repeat field in the entire tape longitudinal direction MD.
- the spacing of threads extending in the band longitudinal direction MD within a respective group G1 with threads 4, 6 or 8, 10 or 12, 14 or 16, 2 is smaller than the spacing between the individual groups G1.
- These groups G1 thus act as a virtual "thicker" thread over which a respective thread B1, B2, B3, B4, B5, B6, B7, B8 extending in the transverse tape direction CMD sets to produce a respective binding position X.
- tie-down points X which exert forces on the threads 2, 4, 6, 8, 10, 12, 14, 16 of the machine-side fabric layer 100 extending in the tape longitudinal direction MD such that the same applies Threads 4, 6 and 8, 10 and 12, 14 and 16, 2 to be loaded on each other.
- group G2 there are two tying points X1, X2 which are positioned in the transverse tape direction CMD on both sides of the two yarns to be gathered into a group G1.
- the tying point of the thread B3 over the thread 10 can be considered as a first tying point X1, while the tying point of the thread B2 above the thread 16 can be considered as a second tying point X2.
- the thread B3 exerts a force on the thread 12, which loads it in the direction of the thread 14, while the thread B2 exerts a force on the thread 14, which loads it in the direction of the thread 12.
- Another pair of bonding sites X within such a group G2 is positioned so that it lies in the band longitudinal direction MD on both sides of the first and second bonding sites X1, X2 mentioned above, but lies between these two bonding sites X1, X2 in the band transverse direction CMD.
- the tying point of the thread B1 over the thread 12 can be considered as a third tying point X3 of the group G2, while the tying point of the thread B4 over the thread 14 can be considered as a fourth tying point X4.
- the third Abbindestelle X3 a force is generated, which spreads the threads 10 and 12 apart, while a force is generated by the fourth Abbindestelle X4, which spreads the threads 14 and 16 apart.
- Another effect generated by the provision of the binding sites X in a defined positioning is that not only the pairing of in the band longitudinal direction MD extending filaments B2-B16 is supported, but that also in the band transverse direction CMD adjacent filaments B1-B8 each to groups or couples.
- Fig. 1 This is illustrated on the left edge of the diagram by the respective threads B2, B3 or B4, B5 etc. summary brackets.
- This effect is produced by the fact that in a respective group G2, the third tie-off point X3 and the fourth tie-off point X4 are positioned so that between these two then threads that are to be gathered or combined into a pair and extend in the transverse tape direction CMD.
- the offsets generated at the respective binding sites X are not only present at the filaments extending in the band transverse direction CMD. Also extending in the tape longitudinal direction MD threads 2 to 16 are bent at these Abbindestellen, ie deflected from its rectilinear extent and produce with this crank a force in the tape longitudinal direction MD, which is exerted on an immediately adjacent in the tape transverse direction CMD extending thread.
- the thread 12 of the fabric layer 100 which sets at the bonding point X3 with the thread B1 presses the thread B2 which immediately follows in the longitudinal direction MD of the strip in the illustration of FIG Fig. 1 downward.
- the thread B3 extending in the transverse tape direction CMD is pressed upward, so that here by the group G2, in particular the tying points X3 and X4, the yarns B2 and B3 are moved closer to each other and, for example, the yarns B1 and B2 are spread apart.
- This effect utilizes the present invention to arrange a pair of binder threads between two such threads forming a thread group in the transverse direction CMD, in the example described above, the pair formed by binding threads Bi1 and Bi2.
- the yarns B2 and B3 thus closer to each other thus form a protection for the binder thread pairs enclosed there, in particular on the machine side 108, so that they are subjected to less stress, in particular in interaction with the various rollers driving or deflecting such a belt.
- FIG. 1 Another in Fig. 1 clearly recognizable special effect in the pairing of extending in the strip transverse direction CMD threads B1 to B8 interacting with the binding threads Bi1-Bi8 extending in the same direction is that the bonding sites X contributing to pair formation in a respective group B2, ie in particular the bonding sites X3 and X4, are positioned exactly there, ie those in the band longitudinal direction MD extending filaments are formed, which are summarized by a respective binder thread to a pair.
- binding thread Bi1-Bi8 on the machine side 108 of extending in the tape longitudinal direction MD threads 2 to 16 of the fabric layer 100, so this runs very exposed in terms of a wear-critical interaction with driving or deflecting rollers that in the strip transverse direction CMD extending and these binding threads enclosing threads B1-B8 are burdened by the Abbindestellen X3, X4 to each other and thus produce exactly at this critical position effective protection for a respective binder thread.
- the tape longitudinal direction MD ie the machine direction
- the tape transverse direction CMD ie the cross machine direction
- the number of threads in a respective group G1 may be different than in the illustrated example, but it has been found that the selection of groups G1 with two threads each has the desired effect of combining or loading
- the groups G1 can be oriented in such a way that they extend in the transverse direction CMD of the belt.

Description
Die vorliegende Erfindung betrifft ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial, insbesondere Papier oder Karton, umfassend eine bahnmaterialseitige erste Gewebelage und eine maschinenseitige zweite Gewebelage, jeweils mit in einer Bandlängsrichtung sich erstreckenden Fäden und in einer Bandquerrichtung sich erstreckenden Fäden, wobei die erste Gewebelage und die zweite Gewebelage durch paarweise einander zugeordnete Bindefäden miteinander verbunden sind.The present invention relates to a fabric tape for a machine for producing web material, in particular paper or cardboard, comprising a web material-side first fabric layer and a machine-side second fabric layer, each with extending in a tape longitudinal direction filaments and in a transverse direction transverse filaments, wherein the first fabric layer and the second fabric layer are connected to each other by pairwise associated binding threads.
Ein derartiges Gewebeband, welches beispielsweise als Formiersieb in einer Maschine zur Herstellung von Papier oder Karton eingesetzt werden kann, ist aus der
Ein Gewebeband gemäß dem Oberbegriff des vorliegenden Anspruch 1 ist aus dem Dokument
Es ist die Zielsetzung der vorliegenden Erfindung ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial vorzusehen, bei welchem durch den Einsatz dickerer Fäden zum Aufbau einer Maschinenkontaktoberfläche ohne Dickenzunahme der Gesamtstruktur eine erhöhte Standfestigkeit erzielt werden kann.It is the object of the present invention to provide a fabric tape for a machine for producing sheet material, in which an increased stability can be achieved by the use of thicker threads to build a machine contact surface without increasing the thickness of the overall structure.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial, insbesondere Papier oder Karton, umfassend eine bahnmaterialseitige erste Gewebelage und eine maschinenseitige zweite Gewebelage, jeweils mit in einer Bandlängsrichtung sich erstreckenden Fäden und in einer Bandquerrichtung sich erstreckenden Fäden, wobei die erste Gewebelage und die zweite Gewebelage durch paarweise einander zugeordnete Bindefäden miteinander verbunden sind,
- wobei die Bindefadenpaare mit in einer Richtung von Bandlängsrichtung und Bandquerrichtung sich erstreckenden Fäden der zweiten Gewebelage derart abbinden, dass in der zweiten Gewebelage in der anderen Richtung von Bandlängsrichtung und Bandquerrichtung aufeinander folgende Gruppen von durch die Bindefäden zusammengefassten in der einen Richtung sich erstreckenden Fäden gebildet sind,
- wobei innerhalb eines in der Bandlängsrichtung und der Bandquerrichtung ausgedehnten Rapportfeldes der zweiten Gewebelage die in der anderen Richtung von Bandlängsrichtung und Bandquerrichtung sich erstreckenden Fäden der zweiten Gewebelage an den in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage zum Bilden jeweiliger Abbindestellen an einer von einer Maschinenkontaktseite abgewandten Seite derart abbinden, dass in dem Rapportfeld wenigstens eine Gruppe von Abbindestellen gebildet ist, die Fäden einer Gruppe von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage in der anderen Richtung aufeinander zu belasten und Fäden einer Gruppe von in der anderen Richtung sich erstreckenden Fäden der zweiten Gewebelage in der einen Richtung aufeinander zu belasten.
- wherein the binder thread pairs with in a direction of tape longitudinal direction and transverse direction transverse threads of the second fabric layer set such that in the second fabric layer in the other direction of the tape longitudinal direction and tape transverse direction successive groups of combined by the binding threads in one direction extending filaments are formed .
- wherein, within a repeat field of the second fabric layer extended in the tape longitudinal direction and the tape transverse direction, the second fabric layer filaments extending in the other direction from the tape longitudinal direction and the tape transverse direction adjoin the unidirectionally extending filaments of the second fabric layer to form respective bonding sites at one of a machine contact side such that in the repeat field at least one group of bonding sites is formed to load the yarns of a group of unidirectionally extending yarns of the second fabric layer in the other direction and yarns of one group extend in the other direction To load threads of the second fabric layer in the one direction to each other.
Bei dem erfindungsgemäßen Gewebeband werden also in einer Richtung sich erstreckende Gruppen von Fäden generiert, wobei in diesen Gruppen durch das Zusammenfassen der Fäden bzw. das Belasten der Fäden aufeinander zu der gegenseitige Abstand der Fäden kleiner ist, als der Abstand einzelner Gruppen untereinander. Infolgedessen können beispielsweise für die in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage vergleichsweise dünne Fäden eingesetzt werden, die durch das Zusammenfassen zu Gruppen gleichwohl als "dickere Fäden" wirken, die dann zusammen mit den in der anderen Richtung sich erstreckenden Fäden der zweiten Gewebelage, die tatsächlich eine größere Querschnittsabmessung aufweisen können, ohne die Nachteile, die der Einsatz generell sehr grober Gewebestrukturen mit dicken Fäden mit sich bringen würde, eine sehr stabile, standfeste Maschinenkontaktoberfläche erzeugen.In the fabric tape according to the invention are thus in one direction generates extending groups of threads, in these groups by the summarization of the threads or the loading of the threads on each other to the mutual distance of the threads is smaller than the distance of individual groups with each other. As a result, for example, for the threads of the second fabric layer extending in one direction, comparatively thin threads can be used, which by grouping together nevertheless act as "thicker threads", which then together with the threads of the second fabric layer extending in the other direction which, in fact, can have a larger cross-sectional dimension without creating the disadvantages of using generally very coarse, thick-filament fabric structures to produce a very stable, stable machine contact surface.
Um in der anderen Richtung eine gleichmäßige Struktur erzeugen zu können, wird vorgeschlagen, dass in der anderen Richtung nebeneinander liegende Gruppen von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage die gleiche Anzahl an Fäden umfassen.In order to be able to produce a uniform structure in the other direction, it is proposed that adjacent groups of unidirectionally extending filaments of the second fabric layer comprise the same number of filaments in the other direction.
Der Erfindungsaspekt des Zusammenfassens einzelner in der einen Richtung sich erstreckender Fäden der zweiten Gewebelage zu Gruppen, die dann in Verbindung mit den quer dazu, also in der anderen Richtung sich erstreckenden Fäden der zweiten Gewebelage verwoben sind, ist insbesondere dann sehr effizient ausnutzbar, wenn jede Gruppe von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage zwei Fäden umfasst.The aspect of the invention of combining individual threads of the second fabric layer extending in one direction into groups, which are then interwoven in connection with the threads of the second fabric layer extending transversely thereto, ie in the other direction, can be exploited very efficiently, in particular if each Group of threads extending in the one direction of the second fabric layer comprises two threads.
Beispielsweise kann die Wechselwirkung der Bindefadenpaare mit den in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage derart sein, dass bei einem Bindefadenpaar alternierend ein Bindefaden an der Maschinenkontaktseite einer Gruppe von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage verläuft und der andere Bindefaden an der Maschinenkontaktseite der übernächsten Gruppe von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage verläuft.For example, the interaction of the pairs of binder yarns with the unidirectional yarns of the second fabric layer may be such that a binder yarn pair alternately has a binder yarn on the machine contact side of a group of yarns of the second fabric layer extending in one direction and the other binder yarn the machine contact page of the next but one group of in the extending one direction extending threads of the second fabric layer.
Weiter ist es möglich, dass bei in der einen Richtung unmittelbar aufeinander folgenden Bindefäden alternierend ein Faden eines Paars an der Maschinenkontaktseite einer Gruppe von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage verläuft und ein Faden eines folgenden Paars an der Maschinenkontaktseite einer in der anderen Richtung unmittelbar folgenden Gruppe von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage verläuft. Auf diese Art und Weise kann es vermieden werden, dass bei ein- und demselben Paar von Bindefäden deren Kreuzungspunkte beim Übergang von der ersten Gewebelage zur zweiten Gewebelage bzw. umgekehrt zwischen zwei unmittelbar benachbarten Gruppen von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage entstehen. Vielmehr kann ein derartiger Kreuzungspunkt jeweils an einer Bahnmaterialseite einer weiteren Gruppe von Fäden der zweiten Gewebelage angeordnet sein.Further, in the one direction immediately succeeding binding threads, it is possible to alternately pass one thread of a pair on the machine contact side of a group of unidirectionally extending threads of the second fabric layer and one thread of a following pair on the machine contact side one in the other Direction immediately following group of extending in one direction threads of the second fabric layer. In this way, it can be avoided that arise in one and the same pair of binding threads whose crossing points in the transition from the first fabric layer to the second fabric layer or vice versa between two immediately adjacent groups of extending in one direction threads of the second fabric layer , Rather, such a crossing point can be arranged in each case on a web material side of a further group of threads of the second fabric layer.
Weiter kann zum Erhalt einer sehr fein strukturierten Bahnmaterialkontaktoberfläche vorgesehen sein, dass zwischen zwei in der einen Richtung aufeinander folgenden Bindefadenpaaren jeweils zwei sich in der anderen Richtung erstreckende Fäden der ersten Gewebelage und zwei sich in der anderen Richtung erstreckende Fäden der zweiten Gewebelage vorgesehen sind. Es sei hier darauf hingewiesen, dass selbstverständlich in der einen Richtung die Anzahl der jeweils vorhandenen Fäden der ersten Gewebelage bzw. der zweiten Gewebelage anders gewählt sein kann, was davon abhängt, wie stark die gegenseitige Anbindung der beiden Gewebelagen sein soll.Furthermore, in order to obtain a very finely structured web material contact surface it can be provided that two threads of the first fabric layer extending in the other direction and two threads of the second fabric layer extending in the other direction are provided between two binding thread pairs succeeding one another. It should be noted here that, of course, in one direction, the number of existing threads of the first fabric layer or the second fabric layer can be chosen differently, which depends on how strong the mutual connection of the two fabric layers should be.
Zum Zusammenfassen einzelner Fäden zu einer jeweiligen Gruppe durch das Bereitstellen definiert angeordneter Abbindestellen wird vorgeschlagen, dass bei jeder Gruppe von Abbindestellen eine erste Abbindestelle und eine zweite Abbindestelle in der anderen Richtung beidseits der von durch diese Gruppe von Abbindestellen aufeinander zu belasteten Fäden einer Gruppe von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage gebildet sind. Dabei kann vorgesehen sein, dass die erste Abbindestelle und die zweite Abbindestelle durch unmittelbar benachbarte in der anderen Richtung sich erstreckende Fäden der zweiten Gewebelage gebildet sind.To summarize individual threads to a respective group by providing defined placement sites, it is proposed that, for each group of attachment sites, a first termination site and a second termination site in the other direction be located on both sides of the latter Group of binding sites on each other to be loaded threads of a group of unidirectionally extending threads of the second fabric layer are formed. It can be provided that the first ligation point and the second ligation point are formed by immediately adjacent in the other direction extending threads of the second fabric layer.
Weiterhin kann eine derartige Gruppe von Abbindestellen eine dritte Abbindestelle und eine vierte Abbindestelle umfassen, die in der einen Richtung beidseits der ersten Abbindestelle und der zweiten Abbindestelle und in der anderen Richtung zwischen der ersten Abbindestelle und der zweiten Abbindestelle gebildet sind. Dabei kann vorgesehen sein, dass die dritte Abbindestelle und die vierte Abbindestelle an unmittelbar benachbarten in der einen Richtung sich erstreckenden Fäden einer Gruppe von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage gebildet sind.Furthermore, such a group of tying sites may include a third tying site and a fourth tying site formed in one direction on both sides of the first tying site and the second tying site and in the other direction between the first tying site and the second tying site. It can be provided that the third ligation point and the fourth ligation point are formed on immediately adjacent in the one direction extending threads of a group of extending in one direction threads of the second fabric layer.
Die gemäß einem Erfindungsaspekt vorgesehenen Gruppen von Abbindestellen können neben dem vorangehend bereits diskutierten Aspekt des Bildens von in der einen Richtung sich erstreckenden Fäden zusätzlich auch noch den Effekt einer Gruppenbildung von in der anderen Richtung sich erstreckenden Fäden mit sich bringen. Durch die an den Abbindestellen gebildeten Abkröpfungen nicht nur der in der anderen Richtung sich erstreckenden Fäden, sondern auch der in der einen Richtung sich erstreckenden Fäden werden insbesondere diejenigen in der anderen Richtung sich erstreckenden Fäden aufeinander zu belastet, die zwischen zwei in der einen Richtung in Abstand zueinander angeordneten Abbindestellen, also insbesondere der dritten und der vierten Abbindestelle, positioniert sind.In addition to the previously discussed aspect of forming threads extending in one direction, the groups of tie sites provided in accordance with one aspect of the invention may additionally entail the effect of grouping threads extending in the other direction. By means of the offsets formed at the attachment points not only of the threads extending in the other direction but also of the threads extending in one direction, in particular those threads extending in the other direction are loaded against each other between two in one direction Distance from each other arranged Abbindestellen, ie in particular the third and fourth Abbindestelle, are positioned.
Um diesen Effekt der Gruppenbildung von in der anderen Richtung sich erstreckenden Fäden weiter positiv nutzen zu können, wird vorgeschlagen, dass zwischen den die erste Abbindestelle und die zweite Abbindestelle bildenden in der anderen Richtung sich erstreckenden Fäden der zweiten Gewebelage ein Bindefadenpaar angeordnet ist. Auf diese Art und Weise werden die Bindefäden eines jeweiligen Bindefadenpaars eng eingefasst und somit auch gestützt durch diejenigen Fäden, die durch zwei oder mehrere Abbindestellen zu in der anderen Richtung sich erstreckenden und in der einen Richtung dann nebeneinander liegenden Gruppen zusammengefasst sind.In order to be able to continue to positively use this effect of group formation of threads extending in the other direction, it is proposed that the threads of the second thread extending in the other direction form between the threads forming the first bonding zone and the second bonding zone Fabric layer is arranged a binder thread pair. In this way, the binding threads of a respective pair of binding threads are tightly bordered and thus also supported by those threads, which are combined by two or more tie-down points to in the other direction extending and then in one direction then adjacent groups.
Die zweite Gewebelage, also diejenige Gewebelage, welche auch den Kontakt mit den verschiedenen umlenkenden bzw. antreibenden Walzen herstellt, kann beispielsweise so aufgebaut sein, dass in einem Rapportfeld jeder in der anderen Richtung sich erstreckende Faden der zweiten Gewebelage an einem einzigen in der einen Richtung erstreckenden Faden der zweiten Gewebelage zum Bilden einer Abbindestelle abbindet, oder/und dass in einem Rapportfeld an jedem in der einen Richtung sich erstreckenden Faden der zweiten Gewebelage ein einziger in der anderen Richtung sich erstreckender Faden der zweiten Gewebelage abbindet.The second fabric layer, ie the fabric layer which also makes contact with the various deflecting or driving rollers, can for example be constructed such that in a repeat field each thread of the second fabric layer extending in the other direction adjoins a single one direction extending thread of the second fabric layer for forming a Abbindestelle sets, and / or that in a repeat field at each in one direction extending thread of the second fabric layer, a single in the other direction extending thread of the second fabric layer sets.
Weiter wird vorgeschlagen, dass zwischen zwei in der anderen Richtung aufeinander folgenden Abbindestellen eines in der anderen Richtung sich erstreckenden Fadens der zweiten Gewebelage dieser Faden an der Maschinenseite von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage verläuft. Auf diese Art und Weise ist sichergestellt, dass diejenigen Fäden der zweiten Gewebelage, die bei der erfindungsgemäßen Ausgestaltung mit größerer Abmessung, also größerer Dicke gewählt werden können, tatsächlich in wesentlichen Bereichen auch die Maschinenkontaktoberfläche erzeugen.It is further proposed that between two threads in the other direction successive lacing points of a thread extending in the other direction of the second fabric layer of this thread on the machine side extends in one direction extending threads of the second fabric layer. In this way it is ensured that those threads of the second fabric layer, which can be selected in the embodiment according to the invention with a larger dimension, ie greater thickness, actually produce the machine contact surface in substantial areas.
Das Zusammenfassen der in der einen Richtung sich erstreckenden Fäden zu einzelnen Gruppen, die vorzugsweise in der einen Richtung sich vollständig über das gesamte Band hinwegerstrecken, erfolgt dann besonders effizient, dass durch eine Gruppe von Abbindestellen in der anderen Richtung aufeinander zu belastete Fäden einer Gruppe von in der einen Richtung sich erstreckenden Fäden der zweiten Gewebelage auch durch in der anderen Richtung sich erstreckende Bindefäden zu einer Gruppe zusammengefasst sind.The combining of the threads extending in one direction into individual groups, which preferably extend in one direction completely over the entire band, then takes place particularly efficiently, such that threads of a group of yarns which are to be loaded on one another by one group of bonding sites in the other direction in one direction extending threads of the second fabric layer are also summarized by extending in the other direction binding threads into a group.
Die eine Richtung kann beispielsweise der Bandlängsrichtung entsprechen, wobei dann die andere Richtung der Bandquerrichtung entspricht. Aus herstellungstechnischen Gründen ist dabei vorzugsweise weiter vorgesehen, dass die eine Richtung einer Kettrichtung und die andere Richtung einer Schussrichtung entspricht.The one direction may, for example, correspond to the band longitudinal direction, in which case the other direction corresponds to the band transverse direction. For manufacturing reasons, it is preferably further provided that the one direction corresponds to a warp direction and the other direction corresponds to a weft direction.

In der Bandlängsrichtung MD erstrecken sich in der maschinenseitigen Gewebelage 100 Fäden 2, 4, 6, 8, 10, 12, 14, 16, welche Bandlängsrichtung MD also auch einer Maschinenlaufrichtung entspricht, während gleichermaßen in der bahnmaterialseitigen Gewebelage 102 Fäden 1, 3, 5, 7, 9, 11, 13 und 15 sich in der Bandlängsrichtung MD erstrecken. Beispielsweise folgen in der Bandlängsrichtung MD in der bahnmaterialseitigen Gewebelage 102 die Fäden T1-T8 in einem jeweiligen Rapportfeld, das die kleinste Wiederholungseinheit in Bandlängsrichtung MD und Bandquerrichtung CMD definiert, aufeinander.In the band longitudinal direction MD, 100
Nach jeweils zwei in der Bandquerrichtung CMD sich erstreckenden Fäden T1, T2 der bahnmaterialseitigen Gewebelage 102 und entsprechender Weise zwei Fäden B1 und B2 der maschinenseitigen Gewebelage 100 folgt ein Paar aus einander zugeordneten Bindefäden Bi1, Bi2, Bi3, Bi4, Bi5, Bi6, Bi7, Bi8. D.h., innerhalb jedes Rapportfeldes existieren in der Bandlängsrichtung MD aufeinander folgend mehrere derartige Bindefadenpaare Bi1-2, Bi3-4, Bi5-6, Bi7-8. Bei jedem Bindefadenpaar wechseln die einzelnen Bindefäden, wie beispielsweise anhand des Bindefadenpaares Bi1-2 veranschaulicht, an Kreuzungspunkten K zwischen der bahnmaterialseitigen Gewebelage 102 und der maschinenseitigen Gewebelage 104. Dort, wo die jeweiligen Bindefäden Bi1 bzw. Bi2 in die bahnmaterialseitige Gewebelage 102 eingebunden sind, bilden diese zusammen mit den in der Bandlängsrichtung MD sich erstreckenden Fäden 1, 3, 5, 7, 9, 11, 13, 15 eine Leinwandbindung, so dass an der Bahnmaterialseite 106 eine sehr fein strukturierte Bahnmaterialkontaktoberfläche gebildet wird. Die Bindefäden Bi1, Bi2, Bi3, Bi4, Bi5, Bi6, Bi7, Bi8 sind hier also auch Struktur bildend eingesetzt, so dass jedes Bindefadenpaar Bi1-2, Bi3-4, Bi5-6, Bi7-8 in der bahnmaterialseitigen Gewebelage 104 tatsächlich einen vollständigen und in der Bandquerrichtung CMD sich erstreckenden Faden ersetzt.After in each case two threads T1, T2 of the web material-
In der maschinenseitigen Gewebelage 100 verlaufen grundsätzlich die in der Bandquerrichtung CMD sich erstreckenden Fäden B1, B2, B3, B4, B5, B6, B7 und B8 an einer Maschinenseite 108 zugewandten Seite der entsprechenden in der Bandlängsrichtung MD sich erstreckenden Fäden 2, 4, 6, 8, 10, 12, 14, 16 dieser Gewebelage 100. Innerhalb eines Rapportfeldes bindet jedoch jeder der in der Bandquerrichtung CMD sich erstreckenden Fäden B1-B8 an einer Abbindestelle X über einen der Fäden 2, 4, 6, 8, 10, 12, 14, 16 dieser Gewebelage 100 ab. Der Ausdruck "über" bedeutet hier, dass das Abbinden an der von der Maschinenseite 108 abgewandten Seite eines jeweiligen in der Bandlängsrichtung MD sich erstreckenden Fadens erfolgt, wie dies beispielsweise anhand der Abbindestelle X des Fadens B1 in
Man erkennt insbesondere in
Er ergibt sich somit die auch in
In der Bandlängsrichtung MD fassen einander unmittelbar benachbarte Bindefadenpaare Bi1-2, Bi3-4 bzw. Bi5-6 alternierend jeweils in der Bandlängsrichtung MD sich erstreckende Fäden zu Gruppen G1 zusammen.In the band longitudinal direction MD, mutually immediately adjacent pairs of binder thread Bi1-2, Bi3-4 and Bi5-6, respectively, extend in each case in the band longitudinal direction MD extending threads to form groups G1.
Es entsteht somit eine Struktur von Gruppen G1 in der Bandlängsrichtung MD sich erstreckender Fäden, die hier gebildet sind durch die Fäden 4, 6 bzw. 8, 10 bzw. 12, 14 bzw. 16, 2 (im Angrenzungsbereich zweier Rapportfelder). Diese Gruppen G1 erstrecken sich in der gesamten Bandlängsrichtung MD durch das Rapportfeld hindurch. Der Abstand von in der Bandlängsrichtung MD sich erstreckenden Fäden innerhalb einer jeweiligen Gruppe G1 mit Fäden 4, 6 bzw. 8, 10 bzw. 12, 14 bzw. 16, 2 ist dabei kleiner, als der Abstand zwischen den einzelnen Gruppen G1. Diese Gruppen G1 wirken somit als virtueller "dickerer" Faden, über welchem ein jeweiliger in der Bandquerrichtung CMD sich erstreckender Faden B1, B2, B3, B4, B5, B6, B7, B8 zum Erzeugen einer jeweiligen Abbindestelle X abbindet. Dadurch wird es möglich, trotz des Einsatzes vergleichsweise dünner in der Bandlängsrichtung MD sich erstreckender Fäden 2, 4, 6, 8, 10, 12, 14, 16 der maschinenseitigen Gewebelage 100 vergleichsweise dicke in der Bandquerrichtung CMD sich erstreckende Fäden B1-B8 einzusetzen, die entsprechend dann auch eine höhere Verschleißfestigkeit bereitstellen.This results in a structure of groups G1 in the band longitudinal direction MD extending threads, which are formed here by the
Dieser Verlauf der Bindefäden Bi1-Bi6 bzw. die Lage von deren Kreuzungspunkten K, die in
Einen weiteren Beitrag zur Bildung einzelner Gruppen G1 von Fäden in der maschinenseitigen Gewebelage 100, die dann trotz vergleichsweise dünnen Fadenmaterials als scheinbar dickerer Faden wirken, wird durch die definierte Positionierung der Abbindestellen X der in der Bandquerrichtung CMD sich erstreckenden Fäden B1-B8 erlangt. Dies wird im Folgenden mit Bezug auf die
Dort erkennt man zwei in jeweiligen Kreisen eingefasste Gruppen G2 von Abbindestellen X, welche auf die in der Bandlängsrichtung MD sich erstreckenden Fäden 2, 4, 6, 8, 10, 12, 14, 16 der maschinenseitigen Gewebelage 100 derartige Kräfte ausüben, dass gleichermaßen die Fäden 4, 6 bzw. 8, 10 bzw. 12, 14 und 16, 2 aufeinander zu belastet werden. Bei einer derartigen Gruppe G2 existieren zwei Abbindestellen X1, X2, die in der Bandquerrichtung CMD beidseits der beiden zu einer Gruppe G1 zusammenzufassenden Fäden positioniert sind. Bei der in der
Aus dieser Erklärung erkennt man, dass jede dieser Gruppen G2 von Abbindestellen X innerhalb eines Rapportfeldes zwei in der Bandlängsrichtung MD sich erstreckende Fäden aufeinander zu belastet, die gleichzeitig auch durch ein Bindefadenpaar zu einer Gruppe G1 von in der Bandlängsrichtung MD sich erstreckenden Fäden zusammengefasst sind. Die beiden durch die Bindefäden und die Abbindestellen generierten Effekte unterstützen sich somit gegenseitig.From this explanation one recognizes that each of these groups G2 of Abbindestellen X within a repeat field two in the tape longitudinal direction MD extending yarns loaded on each other, which are simultaneously summarized by a pair of binder yarn to a group G1 of extending in the tape longitudinal direction MD threads. The two effects generated by the binding threads and the binding sites thus support each other.
Ein weiterer durch das Vorsehen der Abbindestellen X in definierter Positionierung erzeugter Effekt ist, dass nicht nur die Paarbildung von in der Bandlängsrichtung MD sich erstreckenden Fäden B2-B16 unterstützt wird, sondern dass auch in der Bandquerrichtung CMD nebeneinander liegende Fäden B1-B8 jeweils zu Gruppen bzw. Paaren zusammengefasst werden. In
Diesen Effekt wiederum nutzt die vorliegende Erfindung, um jeweils zwischen zwei derartigen, eine in der Bandquerrichtung CMD sich erstreckendes Fadengruppe bildenden Fäden ein Bindefadenpaar, in dem vorangehend beschriebenen Beispiel das durch Bindefäden Bi1 und Bi2 gebildete Paar, anzuordnen. Die somit näher aufeinander zu rückenden Fäden B2 und B3 bilden somit insbesondere an der Maschinenseite 108 einen Schutz für die dort eingefassten Bindefadenpaare, so dass diese insbesondere auch in der Wechselwirkung mit den verschiedenen ein derartiges Band antreibenden bzw. umlenkenden Walzen einer geringeren Belastung unterliegen.
Es sei in diesem Kontext darauf hingewiesen, dass man in der
It should be noted in this context that one in the

Bei dem vorangehend beschriebenen Beispiel eines Gewebebandes kann vorzugsweise die Bandlängsrichtung MD, also die Maschinenrichtung, der Kettrichtung bei der Herstellung eines derartigen Bandes entsprechen, während dann die Bandquerrichtung CMD, also die Quermaschinenrichtung, der Schussrichtung entsprechen kann. Dies kann selbstverständlich auch umgekehrt sein. Auch ist darauf hinzuweisen, dass die Anzahl der Fäden in einer jeweiligen Gruppe G1 anders sein kann, als im dargestellten Beispiel, wobei sich jedoch gezeigt hat, dass durch die Auswahl von Gruppen G1 mit jeweils zwei Fäden der gewünschte Effekt des Zusammenfassens bzw. des Belastens aufeinander zu besonders effizient erzielt werden kann, insbesondere in Verbindung mit einer Achteratlasbindung der maschinenseitigen Gewebelage 100. Auch sei darauf hingewiesen, dass grundsätzlich die Gruppen G1 so orientiert sein können, dass sie sich in der Bandquerrichtung CMD erstrecken.Another in
In the example of a fabric tape described above, the tape longitudinal direction MD, ie the machine direction, may preferably correspond to the warp direction in the production of such a tape, while then the tape transverse direction CMD, ie the cross machine direction, may correspond to the weft direction. Of course, this can also be the other way around. It should also be pointed out that the number of threads in a respective group G1 may be different than in the illustrated example, but it has been found that the selection of groups G1 with two threads each has the desired effect of combining or loading It can also be pointed out that, in principle, the groups G1 can be oriented in such a way that they extend in the transverse direction CMD of the belt.
