Definitions
- the present invention relates to a fabric tape for a machine for producing web material, in particular paper or cardboard, according to the preamble of claim 1.
- Binder thread segments especially in the first fabric layer formed binder thread segments are known, for example, extend over five Grunditatisfäden, wherein the binder thread involved binds over the first, the third and the fifth ground weave thread of each binding segment, in the intermediate second and fourth basic binding threads, however, is guided on the inner side facing the second fabric layer.
- binding threads where they form binding segments in the first fabric layer, continue to form the plain weave of the first fabric layer, here a plain weave, so that the two threads of a respective pair of binder threads continue to form an apparent ground weave thread of the first fabric layer in the binding thread direction.
- the very regular weave pattern of the first fabric layer in this case provided by a plain weave continuing essentially over the entire first fabric layer, is superimposed on a comparatively irregular pattern of the binding segments in the second fabric layer. Attempts have been made to reduce as far as possible the marking tendency which such binding segments can bring about by avoiding any regularity, ie providing an arbitrary distribution of the binding segments in the second fabric layer within a binder thread repeat extending in the binding thread direction and transversely thereto.
- a multi-ply papermachine wire is known in which the binding segments in the lower fabric ply are arranged along diagonals.
- a fabric tape for a machine for producing web material in particular paper or cardboard, so for example a forming fabric to design such that another Reduction of the marking tendency can be achieved.
- this object is achieved by a fabric tape for a machine for producing web material, in particular paper or cardboard, with the features of claim 1.
- the present invention counteracts this problem by deviating from a completely arbitrary distribution for the binding segments arranged in the second fabric layer and proceeding to greater regularity by virtue of the or substantially all binding segments within a respective binder thread repeat along the direction of the binding thread or obliquely placed transversely to the binding yarn direction, ie diagonal cross-diagonal diagonals are arranged.
- a respective binder thread repeat therefore, there are generally several virtual lines along which the binding segments are heaped so that, although a certain local accumulation is present, it is given a certain order and thus regularity by the alignment along respective diagonals.
- mutually adjacent binding threads form a pair of binding threads, wherein preferably the binding threads of a pair of binding threads are immediately adjacent to one another.
- the fabric tape is formed with two fabric layers, they are stably connected by the binding threads in that the binding threads in the first fabric layer in binding thread direction form successive binding segments, in which the binding threads are bonded to at least one perpendicular to the binding thread direction extending base binding thread of the first fabric layer ,
- the binding threads of a respective pair of binder threads intersect each other and one of the binding threads for forming a binding segment in the first fabric layer changes thereinto and the changeover points are arranged in a binding thread repeat along a plurality of alternating diagonals.
- the Kirstellendiagonalen can run parallel to the binding segment, which is due to the fact that where binder segments are formed in the second fabric layer, no change points can be present, it is ensured that overlapping diagonals can not occur.
- the changeover diagonals are angled with respect to the binding segment diagonal.
- the Kirstellendiagonalen at least one Kirstellendiagonale of a first type with uninterrupted stringing together of change points and at least one Kirstellendiagonale a second type with interrupted by Kirstellen-Verstellstellen stringed together exchange points.
- irregularity superimposed on a regular pattern can be provided by alternately changing the alternate diodes of the first type and the second type of switching diagonals with a regular pattern.
- the change point offset points are arranged in a regular pattern.
- binding segments of a binding thread of a pair of binder yarns and binding segments of the other binding thread of the same pair of binder yarns alternately follow one another in the direction of the binding thread.
- the pattern of incorporation of the binding threads into the second fabric layer may, for example, be such that, in at least one binding segment diagonal, substantially all successive binding segments are binding segments of the same type or / and formed by binding threads of the same type.
- the binding segments of the same type are basically characterized by the fact that the manner in which a respective binding thread binds with base binding threads of the second layer of fabric is the same, which can affect both the course of a respective binding thread, and the number of basic binding threads involved in the second layer of fabric.
- Binding threads of the same kind are distinguished by the fact that they have the same course, ie the same sequence of binding sites, with respect to one another in relation to the basic bindings of the various fabric layers with which they form binding segments Bindefadenlambasraum but can be offset.
- Binding threads of different types are distinguished by the fact that, independently of the fact that they can be offset with their respective pattern of incorporation into the fabric layers in the longitudinal direction of the binding thread, they have mutually different patterns of incorporation.
- binding segments of different types and / or binding segments formed by binding threads of different types follow one another in at least one binding segment diagonal, wherein preferably the binding segments contained in at least one binding segment diagonal of different types and / or binding segments formed by binding threads of different types alternate in a regular pattern ,
- an aspect of the irregularity is provided, in that binding segments of different types or different binding threads follow each other, which then, however, contribute to a certain homogenization through the regular pattern of mutual alternation.
- binding segment diagonal In order to obtain a certain break in the regular pattern in the aspect of the regularity formed by the binding segment diagonal, it is further proposed that a plurality of binding segment diagonals with mutually different distribution and / or type of binding segments and / or binding segments of different types formed binding segments are present in a binding thread repeat ,
- binding threads with a different course are distinguished by the fact that with respect to the basic weave or fabric layers with which they Form binding segments, have a different sequence of bonding sites and not only in the binding thread longitudinal direction offset from each other, but in principle then have the same sequence of bonding sites or the same pattern of involvement in the basic bonds.
- the binding threads of a pair of binder threads in the first fabric layer form an apparent ground weave thread of the first fabric layer continuing the binding of the first fabric layer.
- a repeat length of the binding threads in the binding thread direction is greater than a repeat length of the plain weave of the first fabric layer and / or the second fabric layer in the binding thread direction.
- the invention further relates to a machine for producing web material, in particular paper or cardboard, which comprises at least one fabric tape designed according to the invention.
- a first embodiment of a weave structure of a fabric tape for a machine for producing web material such. As paper or cardboard described.
- a forming fabric fabric tape is in the in the Fig. 1 a and 1 b illustrated example with two layers of fabric 114, 116 constructed.
- the fabric layer 114 is a first fabric layer positioned on the web material side and carrying the web material to be produced.
- the fabric layer 16 is a machine or running side second fabric layer which comes into contact with the various rollers guiding or driving the belt.
- Fig. 1a a section running in the weft direction of such a fabric strip is shown, so that the threads lying in the plane of the drawing are the weft threads and the threads shown numerically and perpendicular to the plane of the drawing are the warp threads of the fabric strip.
- the weft threads comprise on the one hand the weft threads 118 used for the basic weave of the first fabric layer 114 and the weft threads 120 used for the basic weave of the second fabric layer 116.
- weft threads 118, 120 each remain in the first fabric layer 114 or the second fabric layer 116 and form there the existing warp threads a respective basic commitment.
- the plain weave of the first fabric layer 114 is a plain weave
- the plain weave of the second fabric layer 116 is a five-at-one satin weave. That is, the weft threads 120 of the plain weave of the second fabric layer 116 float over four warp threads each of the second fabric layer 116 and thus provide a wear-resistant surface of the fabric tape which is very well protected against wear.
- binding threads i1-i2, i3-i4, i5-i6, i7-i8, i9-i10, i11-i12, i13-i14, i15-i16, i17-i18 and i19-i20 assigned to each other in pairs lie directly in the warp direction side by side.
- the binding threads of a respective pair of binder threads change between the two fabric layers 114, 116, so that the binder threads i1-i2, for example, among the warp threads 11, 18, 25, 35 and 45 change points of the binding threads i1, i2 arise.
- the binding threads of the respective binder thread pairs are integrated into the first fabric layer 114 in such a way that they continue there the plain weave, ie the plain weave.
- the two binding threads of a respective pair of binder threads in the first, ie paper-side fabric layer 114 also form a fictitious background weave thread incorporated into the first fabric layer 114 and also by the multiple change of binding threads between the individual fabric layers 114, 116 in a binder thread repeat.
- Each of the binding threads i1 to i20 of a binding thread repeat forms a plurality of binding segments S 1 , S 2 , both in the first fabric layer 114 and in the second fabric layer 116.
- a binding segment is in each case formed by a section of the binding thread in question, in which it binds in a respective fabric layer 114 or 116 via at least one, possibly also a plurality and not necessarily immediately adjacent warp threads.
- the binding thread i1 of the uppermost pair of binding threads i1-i2 forms in FIG Fig. 1a a binding segment S 1 in the first fabric layer 114, which extends from the warp thread 3 to the warp thread 10.
- the binding thread 1 binds to the outside of the first fabric layer 114, that is, the side remote from the second fabric layer 116. He is guided under the warp threads 5, 8, so that there is the above-mentioned plain weave.
- Another binding segment S 1 in the first fabric layer 114 forms the binding yarn i1 with the warp threads 20, 21 and 23 or even another with the warp threads 36, 38, 40, 41, 43.
- the binding segments S 1 present in the first fabric layer 114 are each separated by a warp thread 1, 11, 18, 25, 35 and 45, which contributes equally to the preservation of the plain weave.
- Binder segments S 2 are also formed in the second fabric layer 116, wherein, for example, the first binder thread i 1 forms a binding segment S 2 with the warp threads 14, 17. Another binding segment binds this binding thread i1 with the warp threads 27, 29.
- the binding segments also comprise a plurality of warp threads, in particular two directly adjacent warp threads, so that in each binding segment S 2 of the binding thread i1, and equally also the binding thread i2 at the Running side floated over two warp threads.
- binder thread repeat which provides here so the smallest repeating unit of the weave structure, successively repeated in the weft direction and in the warp consecutively put together the entire weave structure with a total of ten pairs of binder threads, basically there are only two types of different bound binding threads. That is, all odd-numbered binding threads i1, i3, ..., i19 have basically the same course with respect to the warp threads, but are offset in the weft direction with respect to one another. The same applies to the even numbered binding threads i2, i4,..., I20.
- binding segments S 1 and S 2 are such that a larger number, namely six, binding segments S1 is present in the first fabric layer 114 than in the first fabric layer 114 second fabric layer 116, where within a binder thread repeat only four binding segments S 2 are present, which are separated from each other by three warp threads. This is due to the fact that each of the two binding threads of a respective pair of binding threads in the first fabric layer 114 forms two binding segments separated by a binding segment of the respective other binding thread, without changing in between into the second fabric layer 116.
- the Fig. 1b shows, viewed from the running side, the positioning of binding segments S 2 in the second fabric layer 116.
- the numbered with 2-49 columns form the Fig. 1b in each case the warp threads of a binder thread repeat of the second fabric layer 116, while the lines represent the weft threads or in particular the binding threads 1-20 provided by weft threads.
- the sequence of successive binding segments S 2 for example of the first pair of binding threads i 1 -i 2 , is clearly recognizable, the sequence always being such that two binding segments S 2 of the binding thread of one type follow two binding segments S 2 of the other binding thread of the other type.
- binding segment diagonals D extend both obliquely to the warp direction and obliquely to the weft direction. It can be seen that within a binder thread repeat there is a plurality of binding segment diagonals D extending substantially parallel to one another, along which the binding segments S 2 of the second fabric layer 116 are arranged consecutively.
- the binding segments S 2 of a diagonal are each offset by a warp thread in the weft direction and overlap in a warp thread.
- the binding segments S 2 of a diagonal are each offset by a warp thread in the weft direction and overlap in a warp thread.
- a certain irregularity in the superimposition of the warp threads itself is produced arranging the binding segments S 2 along the binding segment diagonal D into a tissue band with a very low marking tendency.
- Fig. 1b one recognizes further that in the individual binding segment diagonals D a regularity is also present with regard to the binding segments S 2 contained therein. This is followed in each case by two binding segments S 2 with binding threads of one kind, ie with respect to the two fabric layers 114, 116 basically integrated but mutually offset in the weft direction binding threads on two binding segments S 2 , which are each formed with a binder thread of the other type.
- the Fig. 1c illustrates the position of the binding segments S 1 , which form a respective pair of binder threads i1, i2,... i19, i20 in the first fabric layer 114.
- a binding segment S 1 is replaced by the one in Fig. 1c formed with black color binding yarn i1 at the provided in the first fabric layer 114 warp yarns 3, 5, 6, 8 and 10 is formed.
- the change points W are arranged along change-digit diagonals Dw or D w '.
- the Kirstellendiagonalen D W of a first type are formed by a regularity not interrupting juxtaposition of change points W and extend in this high regularity by in the Fig. 1c represented binder thread repeat or continue across the adjacent Bindefadenrapporte away.
- the binding segment diagonals D W 'of a second type have a sequence of change points W marked by interruptions. At change point offsets V missing in these diagonals D w 'the second kind change points. These are shifted in the binding thread longitudinal direction to offset change points W v .
- change-digit diagonals D w 'of the second type are thus provided with regularity interrupted by the change-point offsets V in the juxtaposition of the change points W.
- the change point offset points V are arranged in regular sequence in these changeover diagonals D W 'of the second type.
- the offset change points W v are in a respective binder thread repeat in a regular pattern, in the example shown also following one another along a diagonal.
- a plurality of alternate diagonals D w of the first type and D w 'of the second type are provided in a binder thread repeat, and these different types of alternating diagonals D w , D w ' alternate alternately, ie also in a regular pattern.
- a modified embodiment of a fabric band or a woven structure within a respective binder thread repeat is in the Fig. 2a and 2 B shown.
- the binding threads of a respective pair of binder threads assigned to one another in pairs for example the binding threads i1 and i2, form the binding segments S 1 , S 2 in the first fabric layer 114 and the second fabric layer 116, respectively.
- binding segments S 2 are present, which extend only over a single warp thread. This is also evident in the Fig.
- binding segments comprising three warp threads can float over these three warp threads, but can also set in the manner of a plain weave over two warp threads separated by one of the warp threads.
- Fig. 3a and 3b show an embodiment variant in which the two binding threads, ie, for example, i1, i2, are separated by a weft thread 20 of the plain weave of the second fabric layer 116 in each binding thread pair.
- binding segments S 2 in the second fabric layer 116 which comprise only one warp thread, are present in each binding yarn pair in the illustrated binder thread repeat.
- a total of two binding segments S 2 with one warp thread and two binding segments S 2 with two warp threads are present.
- the binding thread of one type always forms the binding segments S 2 with two warp threads, while the binding thread of the other type forms the binding segments S 2 with a warp thread.
- binding segments S 2 here comprise only a single warp thread, which also in the Fig. 4b is clearly visible.
- the binding segments S 2 are arranged along the binding segment diagonal D, with groups of four binding segments S 2 being present in the diagonals D, which are separated from one another by a respective warp thread on which no binding segment is then formed at a respective diagonal.
- the individual groups of four each extend over three warp threads, the middle two binding segments being formed in a respective group of four on the same warp thread.
- FIG. 5a and 5b an embodiment variant is shown, in which the again immediately adjacent binding threads of a respective pair of binder thread segments S 2 , each with a warp thread in the second fabric layer 116 form.
- the binding segments S 2 are arranged along the binding segment diagonal D, in which case there are three diagonals D, D 'and D "of different types, and a uniform distribution of the binding segments S 2 is present in the respective diagonals D, D' and D".
- the diagonal D is a sequence of individually arranged binding segments and two in the warp direction immediately adjacent arranged binding segments available.
- the diagonal D ' are each two groups of binding segments S 2 are present, which are separated in the warp direction each by another pair of binder yarns.
- the Fig. 5c shows in association with the in the Fig. 5a and 5b shown embodiment of a fabric tape again the position of the change points of the pairwise associated binding threads i1, i2, ... i19, i20 and in the first fabric layer 114 respectively formed binding segments S 1st
- the sequence of binding segments S 1 formed from a respective pair of binder threads alternately comprises a binding segment S 1 of one binding thread of a pair of binder threads and then a binding segment S 1 of the other binding thread of this pair of binder threads.
- the change points W are again arranged along the change-point diagonals Dw or D w '.
- D w of the first kind is again a regular and not interrupted sequence of change points W exists.
- D w 'of the second kind there are again offset points V and W v offset change points which change the sequence of points in the diagonal of D w' interrupt.
- Fig. 6a there are a total of ten pairs of mutually associated binding threads, where basically two different thread pairs with respect to the yarn path exist.
- the binding thread i5 has the same course with respect to the various warp threads with which it forms binding segments S 1 and S 2 , as the binding thread i1 is displaced with respect to it in the weft direction.
- the binding threads i1 and i3 or the binding threads i2 and i4 differ with respect to their binding to the warp threads.
- a sequence of binding segments S 1 is present, which is 2-3-3-2-3-2, wherein the number specified in each case the number of in a respective binding segment S 1 outside
- the warp threads of the first fabric layer 14 surrounded by a binding thread i1 or i2 are designated.
- the sequence is as follows 3-2-3-2-3-2. This sequence of binding segments S 1 of different types, that is to say in each case a different number of included warp threads, alternates alternately within a respective binder thread repeat.
- the binding segments S 2 of the second fabric layer 116 are oriented along binding segment diagonals D. Since each binding thread forms binding segments of various types, that is to say binding segments comprising a warp thread on the one hand and binding segments comprising two warp threads on the other hand, a sequence of binding segments of different types is present in each binding thread pair. This results in two different diagonals D and D 'arise. In each diagonal D or D 'binding segments S 2 of different types are included, but evenly distributed in their sequence along the diagonal D or D' again.
- the Fig. 6c again shows the position of the change points W and the binding segments S 1 in the first fabric layer 114.
- the Kirschendiagonalen Dw in which a regular and uninterrupted sequence of change points W is present. This does not preclude that here, viewed in the longitudinal direction of the binding threads, between two change points W a Kirstellendiagonale D w of the first kind is a transverse to the binding thread longitudinal direction, ie in the warp direction thread of the first fabric layer is present, at least in association with this Changeover diagonal no change point is formed.
- This uninterrupted sequence of change points is canceled in the Mattstellendiagonalen D w 'of the second type, that in the binder thread repeat each a change points offset point V exists in which the regular sequence is interrupted. Assigned to each change point offset point V is an offset change point W v , which is shifted in the binding thread longitudinal direction by two warp threads.
- the binding thread i1 after having formed a binding segment S 1 on the threads 28, 30, 31 extending transversely to the binding thread longitudinal direction, changes immediately before the thread 33 into the second fabric layer 116 under the thread 34 present there, ie, none Extending portion, in which it extends between the two fabric layers 114, 116 and arranged respectively transverse threads therethrough, as is the case, for example, at the same transition point W in the binding yarn i2 in front of the transverse thread 32 in a position between the two fabric layers 114th , 116 alternates, and extends between the transverse threads 31, 32 on the one hand and then the transverse threads 33, 34 on the other hand through and thereby crosses the binding thread i1 changing directly from the first fabric layer 114 into the second fabric layer 116.
- Fig. 7a and 7b show a modification of the embodiment described above, in which formed in the first fabric layer 14 binding segments S 1 in a kind of binder thread pair again relative to the wrapped warp threads as follows: 2-3-3-2-3-2, while in the other Art of string pair the sequence is as follows: 3-2-3-2-3-2.
- the binding segments S 2 formed in the second fabric layer 116 are arranged along the diagonals D and D ', wherein within the binder segment diagonal D, in particular recognizable by the diagonal D, a comparatively large regularity by a similar repetition of the pattern of the positioning of the binding segments of the type the binding segment or the type of binding threads used to form the binding segments is achieved.
- the Fig. 8a and 8b show a mode of embodiment in which the two pairs of binder thread pairs are each formed with the sequence of binding segments S 1 in the first fabric layer, which reads as follows: 2-3-3-2-3-2 or 3-2-3-2- 3-2.
- four different binder thread pair courses are used to generate two different pairs of binder thread, which then alternate alternately within a binder thread repeat in the warp direction.
- the binding segments S 2 of the second fabric layer are arranged lying along the binding segment diagonals D, D '.
- binding segments S 1 While in the embodiments described above in the first fabric layer in each case six binding segments S 1 are present in the in Fig. 9
- a binder thread pair with a number of eight binding segments S 1 is additionally present alternately.
- the number of binding segments S 2 in the second fabric layer 116 present in a respective binder thread pair is six here. This is also out Fig. 9b recognizable, where in assignment to each Bindefadenrect six such binding segments S 2 can be seen.
- the binding thread pairs of different types differ in that in one type, for example in the binding thread pair i1, i2, only binding segments S 2 are formed which comprise a single warp thread, while in the binding thread pair of another type, thus for example the binding threads i3, i4, in each case a binding segment S 2 is formed, in which the associated binding thread floats over two warp threads away.
- binding segments are again aligned along binding segment diagonals, with a larger number of diagonals D, D ', D "and D'" occurring in a binding thread repeat.
- the binding segments of different diagonals can, for example, continue to touch each other in the warp direction, ie they can lie next to one another in the warp direction.
- the individual diagonals there is a high degree of regularity in the sequence of the binding segments arranged there.
- binding segment diagonal D "'comprising binding segments of various types in each case has an alternating sequence of a binding segment comprising only one warp thread and a binding segment comprising two warp threads with a subsequent separation from a warp thread.
- Fig. 10a and 10b variant embodiment shown comprises at every second binder yarn pair, eight binding segments S 1 in the first fabric layer 114.
- two types of binder yarn pairs ie a total of four different binding thread runs, present, wherein every other binder yarn pair, a binder thread between two therethrough provided binding segments S 1 for a relatively long time, namely over five warp threads present in the first fabric layer 114, between the two fabric layers 114, 116 floats.
- This can be seen, for example, in the binding thread pair i3, i4, in which the binding thread i3 floats over the warp threads 20, 21, 23, 25, 26 of the first fabric layer 114.
- six binder segments S 2 are in each binding thread pair formed, which bind either over a warp thread or two warp threads.
- the Fig. 10b shows that here too the binding segments S 2 of the second fabric layer are arranged along binding segment diagonals D, D '.
- the Fig. 10c shows in association with the Fig. 10a and 10b the arrangement of the change points W and the Kir Wegdiagonalen D w , D w '.
- the Kirstellendiagonalen D w first type each include again provided without interruption of the regularity arrangement of change points W, which are separated in the binding thread longitudinal direction in each case by a transverse to the filament longitudinal direction extending yarn, in this case warp.
- the change-point diagonals D w 'of the second type four change-point offset points V or correspondingly four offset change positions W v are present in each binder thread repeat in association with each such diagonal.
- the offset change points W v can be regarded as defining an independent Kasstellendiagonale the second type, in which the present in the change points D w of the first kind regularity is interrupted by the absence of change points.
- first fabric layer 114 by providing a plain weave, this is also continued by the bound in the first fabric layer 114 binding threads or pairs of binder yarns, a very high regularity is provided, while in the second fabric layer
- the arrangement of the binding segments S 2 formed there along the binding segment diagonals also ensures a certain degree of regularity.
- the following will be with reference to the Fig. 11 to 14 in each case based on two basic binding weft threads 118, 120 for the two fabric layers 114, 116 and two binding threads i1, i2 other types of weave for the first fabric layer 114 shown.
- the binding segments S 1 of the first fabric layer 14 formed by the pairs of binder yarns can each extend over a larger number of warp threads, in the example illustrated five warp threads.
- the floats of the basic binding weft threads 118 of the first fabric layer 114 extend over in each case two warp threads, so that a 1-2 bond is present here.
- a corresponding pattern is also formed by the binding threads of the various binder thread pairs.
- the binding segments S 1 of the first fabric layer 114 extend over a total of five warp threads, a float being present over the first and second or the fourth and fifth warp threads, while the binder thread runs below the middle of these five warp threads, that is to say on the inner side thereof.
- each binding segment S 1 also forms in connection with the fact that in the weft direction successive binding segments S 1 are each separated by a warp thread, the binding of the first fabric layer on.
- the Fig. 13 shows, like the Fig. 11 also, a 1-4 bond in the first fabric ply, wherein the base bond weft yarns 118 of the first fabric ply 114 float on the outside of four warp yarns and then pass under a respective fifth warp yarn.
- the binding segments S 1 formed in the first fabric layer 114 are designed such that they extend over four warp threads in each case, ie a floating over four warp threads is present, while successive binding segments S 1 then pass through a warp thread are separated.
- the binding threads of a respective pair of binder threads continue to form the binding of the basic binding weft threads 118 of the first fabric layer.
- the Fig. 14 combines a 1-4 bond in the first fabric layer 114 with the basic bond weft threads 118 present there with a corresponding bond of the binder thread pairs.
- the binding segments S 1 of the first fabric layer 114 each comprise five warp yarns, the respective binding yarns involved floating on the outside of two warp yarns, then passing under a warp yarn and then floating again on the outside of two warp yarns before changing to a bonding segment which is formed by the respective other binding thread of the same pair of binder threads. Since the binding segments S 1 again directly adjoin one another here, ie are not separated by a weft thread, a binding pattern results, in which a floating over four warp threads is present, but this floating is formed by sections of two different binding threads.
- the binding segments S 2 are formed in the second fabric layer 116, each with a single warp.
- the number of binding segments S 1 here corresponds to the number of binding segments S 2 in a respective binder thread repeat, in particular here in the weft direction.
- a base weave is preferably selected in which the basic weaving weft threads 120 involved have comparatively long floats on the outside, so that in this case a comparatively planar surface interacting with the various guide or drive rolls forms.
- the embodiment according to the invention with the arrangement of existing in the running side fabric layer binding segments along respective Tie diagonal can of course also apply when the binding threads are formed extending in the warp direction. Furthermore, it is possible to provide binding yarns running both in the warp direction and in the weft direction, in which case the above-mentioned positioning of respective binding segments can be realized or superimposed on one another both for the binding threads extending in the warp direction and for the binding threads running in the weft direction.

Description
Die vorliegende Erfindung betrifft ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial, insbesondere Papier oder Karton, nach dem Oberbegriff des Anspruchs 1.The present invention relates to a fabric tape for a machine for producing web material, in particular paper or cardboard, according to the preamble of
Aus der
Dem sehr regelmäßigen Bindungsmuster der ersten Gewebelage, hier also bereitgestellt durch eine sich im Wesentlichen über die gesamte erste Gewebelage fortsetzende Leinwandbindung, ist ein vergleichsweise unregelmäßiges Muster der Bindesegmente in der zweiten Gewebelage überlagert. Hier wurde versucht, durch das Vermeiden jedweder Regelmäßigkeit, also dem Bereitstellen einer willkürlichen Verteilung der Bindesegmente in der zweiten Gewebelage innerhalb eines in Bindefadenrichtung und quer dazu ausgedehnten Bindefadenrapportes, die Markierungsneigung, welche derartige Bindesegmente mit sich bringen können, so weit als möglich zu reduzieren.The very regular weave pattern of the first fabric layer, in this case provided by a plain weave continuing essentially over the entire first fabric layer, is superimposed on a comparatively irregular pattern of the binding segments in the second fabric layer. Attempts have been made to reduce as far as possible the marking tendency which such binding segments can bring about by avoiding any regularity, ie providing an arbitrary distribution of the binding segments in the second fabric layer within a binder thread repeat extending in the binding thread direction and transversely thereto.
Aus der
Es ist die Aufgabe der vorliegenden Erfindung, ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial, insbesondere Papier oder Karton, also beispielsweise ein Formiersieb, derart auszugestalten, dass eine weitere Verringerung der Markierungsneigung erzielt werden kann.It is the object of the present invention, a fabric tape for a machine for producing web material, in particular paper or cardboard, so for example a forming fabric to design such that another Reduction of the marking tendency can be achieved.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial, insbesondere Papier oder Karton, mit den Merkmalen des Anspruchs 1.According to the invention, this object is achieved by a fabric tape for a machine for producing web material, in particular paper or cardboard, with the features of
Es wurde ausgehend von der aus der
Die vorliegende Erfindung tritt diesem Problem dadurch entgegen, dass für die in der zweiten Gewebelage angeordneten Bindesegmente von einer völlig willkürlichen Verteilung abgewichen wird und zu einer größeren Regelmäßigkeit dadurch übergegangen wird, dass die bzw. im Wesentlichen alle Bindesegmente innerhalb eines jeweiligen Bindefadenrapportes entlang von zur Bindefadenrichtung bzw. quer zur Bindefadenrichtung schräg gestellt, also diagonal verlaufenden Bindesegmentdiagonalen angeordnet sind. In einem jeweiligen Bindefadenrapport entstehen somit im Allgemeinen mehrere virtuelle Linien, entlang welchen die Bindesegmente gehäuft angeordnet sind, so dass gleichwohl zwar eine gewisse lokale Häufung vorhanden ist, dieser aber durch das Ausrichten entlang jeweiligen Diagonalen eine gewisse Ordnung und somit Regelmäßigkeit gegeben wird. Durch das Bereitstellen einer geringeren Anzahl an Bindesegmenten in der zweiten Gewebelage wird es möglich, zwischen den einzelnen Bindesegmentdiagonalen einen vergleichsweise großen Zwischenraum zu belassen. Durch das Bereitstellen des erfindungsgemäßen Verhältnisses zwischen Grundbindungsfäden der ersten und zweiten Gewebelage wird es möglich, der vergleichsweise hohen Regelmäßigkeit in der ersten Gewebelage einen Aspekt der Unregelmäßigkeit in der zweiten Gewebelage zu überlagern, mit entsprechend verringerter Markierungsneigung. Es hat sich gezeigt, dass damit eine deutlich reduzierte Markierungsneigung erreichbar ist.The present invention counteracts this problem by deviating from a completely arbitrary distribution for the binding segments arranged in the second fabric layer and proceeding to greater regularity by virtue of the or substantially all binding segments within a respective binder thread repeat along the direction of the binding thread or obliquely placed transversely to the binding yarn direction, ie diagonal cross-diagonal diagonals are arranged. In a respective binder thread repeat, therefore, there are generally several virtual lines along which the binding segments are heaped so that, although a certain local accumulation is present, it is given a certain order and thus regularity by the alignment along respective diagonals. By providing a smaller number of binding segments in the second fabric layer, it becomes possible to leave a comparatively large gap between the individual binder segment diagonals. By providing the ratio according to the invention between base binding threads of the first and second fabric layers, it becomes possible to superimpose on the comparatively high regularity in the first fabric layer an aspect of the irregularity in the second fabric layer, with a correspondingly reduced marking tendency. It has been shown that thus a significantly reduced tendency to mark can be achieved.
Bei dem erfindungsgemäß aufgebauten Gewebeband bilden einander benachbarte Bindefäden ein Bindefadenpaar, wobei vorzugsweise die Bindefäden eines Bindefadenpaares einander unmittelbar benachbart sind.In the fabric band constructed according to the invention, mutually adjacent binding threads form a pair of binding threads, wherein preferably the binding threads of a pair of binding threads are immediately adjacent to one another.
Bei einer alternativen Ausgestaltung ist es möglich, dass zwischen den Bindefäden eines Bindefadenpaares wenigstens ein in Bindefadenrichtung sich erstreckender Grundbindungsfaden der zweiten Gewebelage oder/und wenigstens ein in Bindefadenrichtung sich erstreckender Grundbindungsfaden der ersten Gewebelage angeordnet ist.In an alternative embodiment, it is possible that between the binding threads of a pair of binding thread at least one in the binding thread direction extending base binding thread of the second fabric layer and / or at least one in the binding thread direction extending base binding thread the first fabric layer is arranged.
Da das Gewebeband mit zwei Gewebelagen ausgebildet ist, werden diese durch die Bindefäden dadurch stabil verbunden, dass die Bindefäden in der ersten Gewebelage in Bindefadenrichtung aufeinander folgende Bindesegmente bilden, in welchen die Bindefäden an wenigstens einem quer zur Bindefadenrichtung sich erstreckenden Grundbindungsfaden der ersten Gewebelage abgebunden sind.Since the fabric tape is formed with two fabric layers, they are stably connected by the binding threads in that the binding threads in the first fabric layer in binding thread direction form successive binding segments, in which the binding threads are bonded to at least one perpendicular to the binding thread direction extending base binding thread of the first fabric layer ,
Um durch die Bindefäden unter der Möglichkeit, das durch die Grundbindungsfäden in der ersten Gewebelage erzeugte Bindungsmuster fortsetzen zu können, einen stabilen Zusammenhalt zwischen den Gewebelagen bereitstellen zu können, gleichzeitig jedoch für die erste Gewebelage eine gewisse Regelmäßigkeit bereitstellen zu können, wird weiter vorgeschlagen, dass an Wechselstellen die Bindefäden eines jeweiligen Bindefadenpaares einander kreuzen und einer der Bindefäden zum Bilden eines Bindesegments in der ersten Gewebelage in diese wechselt und das die Wechselstellen in einem Bindefadenrapport entlang einer Mehrzahl von Wechselstellendiagonalen angeordnet sind.In order to be able to provide a stable cohesion between the fabric layers through the binding threads with the possibility of being able to continue the binding pattern produced by the basic binding threads in the first fabric layer, but at the same time being able to provide a certain degree of regularity for the first fabric layer, it is further proposed that at changing points, the binding threads of a respective pair of binder threads intersect each other and one of the binding threads for forming a binding segment in the first fabric layer changes thereinto and the changeover points are arranged in a binding thread repeat along a plurality of alternating diagonals.
Dabei können die Wechselstellendiagonalen zu den Bindesegmentendiagonalen parallel verlaufen, wobei auf Grund der Tatsache, dass dort, wo Bindesegmente in der zweiten Gewebelage gebildet sind, keine Wechselstellen vorhanden sein können, dafür gesorgt ist, dass einander sich überdeckende Diagonalen nicht auftreten können.In this case, the Wechselstellendiagonalen can run parallel to the binding segment, which is due to the fact that where binder segments are formed in the second fabric layer, no change points can be present, it is ensured that overlapping diagonals can not occur.
Bei einer alternativen Variante kann vorgesehen sein, dass die Wechselstellendiagonalen bezüglich der Bindesegmentdiagonalen angewinkelt verlaufen.In an alternative variant, it can be provided that the changeover diagonals are angled with respect to the binding segment diagonal.
Um das durch die Anordnung der Wechselstellen entlang von Wechselstellendiagonalen eingeführte regelmäßige Muster in gewissenTo the introduced by the arrangement of the change points along Wechselstellendiagonalen regular pattern in certain
Bereichen zu unterbrechen und durch geringfügige Unregelmäßigkeiten ein verbessertes Markierungsverhalten zu erzielen, wird vorgeschlagen, dass die Wechselstellendiagonalen wenigstens eine Wechselstellendiagonale einer ersten Art mit unterbrechungsfreier Aneinanderreihung von Wechselstellen und wenigstens eine Wechselstellendiagonale einer zweiten Art mit durch Wechselstellen-Versatzstellen unterbrochener Aneinanderreihung von Wechselstellen umfassen.To interrupt areas and to achieve an improved marking behavior by minor irregularities, it is proposed that the Wechselstellendiagonalen at least one Wechselstellendiagonale of a first type with uninterrupted stringing together of change points and at least one Wechselstellendiagonale a second type with interrupted by Wechselstellen-Verstellstellen stringed together exchange points.
Auch mit den verschiedenen Arten von Wechselstellendiagonalen kann eine einem regelmäßigen Muster überlagerte Unregelmäßigkeit dadurch bereitgestellt werden, dass die Wechselstellendiagonalen der ersten Art und die Wechselstellendiagonalen der zweiten Art einander mit regelmäßigem Muster abwechseln.Also, with the various kinds of alternate diagonals, irregularity superimposed on a regular pattern can be provided by alternately changing the alternate diodes of the first type and the second type of switching diagonals with a regular pattern.
Weiterhin kann vorgesehen sein, dass die Wechselstellen-Versatzstellen in regelmäßigem Muster angeordnet sind.Furthermore, it can be provided that the change point offset points are arranged in a regular pattern.
Weiter ist vorgesehen, dass in der ersten Gewebelage Bindesegmente eines Bindefadens eines Bindefadenpaares und Bindesegmente des anderen Bindefadens desselben Bindefadenpaares in Bindefadenrichtung alternierend aufeinander folgen.It is further provided that in the first fabric layer binding segments of a binding thread of a pair of binder yarns and binding segments of the other binding thread of the same pair of binder yarns alternately follow one another in the direction of the binding thread.
Das Muster der Einbindung der Bindefäden in die zweite Gewebelage kann beispielsweise derart sein, dass in wenigstens einer Bindesegmentdiagonale im Wesentlichen alle aufeinander folgenden Bindesegmente Bindesegmente gleicher Art sind oder/und durch Bindefäden gleicher Art gebildet sind. Die Bindesegmente gleicher Art sind grundsätzlich dadurch charakterisiert, dass die Art und Weise, wie ein jeweiliger Bindefaden mit Grundbindungsfäden der zweiten Gewebelage abbindet, gleich ist, was sowohl den Verlauf eines jeweiligen Bindefadens betreffen kann, als auch die Anzahl der involvierten Grundbindungsfäden der zweiten Gewebelage. Bindefäden gleicher Art zeichnen sich dadurch aus, dass sie, bezogen auf die Grundbindungen der verschiedenen Gewebelagen, mit welchen sie Bindesegmente bilden, den gleichen Verlauf, also die gleiche Abfolge von Abbindestellen aufweisen, bezüglich einander in Bindefadenlängsrichtung aber versetzt liegen können. Bindefäden unterschiedlicher Art zeichnen sich dadurch aus, dass sie, unabhängig davon, dass sie mit ihrem jeweiligen Muster der Einbindung in die Gewebelagen in Bindefadenlängsrichtung versetzt liegen können, zueinander unterschiedliche Muster der Einbindung aufweisen.The pattern of incorporation of the binding threads into the second fabric layer may, for example, be such that, in at least one binding segment diagonal, substantially all successive binding segments are binding segments of the same type or / and formed by binding threads of the same type. The binding segments of the same type are basically characterized by the fact that the manner in which a respective binding thread binds with base binding threads of the second layer of fabric is the same, which can affect both the course of a respective binding thread, and the number of basic binding threads involved in the second layer of fabric. Binding threads of the same kind are distinguished by the fact that they have the same course, ie the same sequence of binding sites, with respect to one another in relation to the basic bindings of the various fabric layers with which they form binding segments Bindefadenlängsrichtung but can be offset. Binding threads of different types are distinguished by the fact that, independently of the fact that they can be offset with their respective pattern of incorporation into the fabric layers in the longitudinal direction of the binding thread, they have mutually different patterns of incorporation.
Weiter kann vorgesehen sein, dass in wenigstens einer Bindesegmentdiagonale Bindesegmente unterschiedlicher Art oder/und durch Bindefäden verschiedener Art gebildete Bindesegmente aufeinander folgen, wobei vorzugsweise die in wenigstens einer Bindesegmentdiagonale enthaltenen Bindesegmente unterschiedlicher Art oder/und durch Bindefäden verschiedener Art gebildete Bindesegmente einander in regelmäßigem Muster abwechseln. Auf diese Art und Weise wird in der durch die Bindesegmentdiagonalen gebildeten Regelmäßigkeit einerseits ein Aspekt der Unregelmäßigkeit vorgesehen, indem Bindesegmente verschiedener Art bzw. verschiedener Bindefäden aufeinander folgen, welche dann aber durch das regelmäßige Muster des gegenseitigen Abwechselns wieder zu einer gewissen Vergleichmäßigung beitragen.It can further be provided that binding segments of different types and / or binding segments formed by binding threads of different types follow one another in at least one binding segment diagonal, wherein preferably the binding segments contained in at least one binding segment diagonal of different types and / or binding segments formed by binding threads of different types alternate in a regular pattern , In this way, in the regularity formed by the binding segment diagonal, on the one hand, an aspect of the irregularity is provided, in that binding segments of different types or different binding threads follow each other, which then, however, contribute to a certain homogenization through the regular pattern of mutual alternation.
Um in dem durch die Bindesegmentdiagonalen gebildeten Aspekt der Regelmäßigkeit eine gewisse Durchbrechung des regelmäßigen Musters zu erlangen, wird weiter vorgeschlagen, dass in einem Bindefadenrapport mehrere Bindesegmentdiagonalen mit zueinander unterschiedlicher Verteilung oder/und Art von Bindesegmenten oder/und durch Bindefäden verschiedener Art gebildeten Bindesegmenten vorhanden sind.In order to obtain a certain break in the regular pattern in the aspect of the regularity formed by the binding segment diagonal, it is further proposed that a plurality of binding segment diagonals with mutually different distribution and / or type of binding segments and / or binding segments of different types formed binding segments are present in a binding thread repeat ,
Bei einer hinsichtlich aufgrund des möglichst einfachen Aufbaus des Bindungsmusters vorteilhaften Variante wird weiter vorgeschlagen, dass in einem Bindefadenrapport die Anzahl der Bindefadenpaare mit zueinander unterschiedlichem Verlauf der diese bildenden Bindefäden kleiner ist als die Anzahl der in einem Bindefadenrapport vorhandenen Bindefadenpaare. Auch hier zeichnen sich Bindefäden mit unterschiedlichem Verlauf dadurch aus, dass sie bezüglich der Grundbindungen bzw. Gewebelagen, mit welchen sie Bindesegmente bilden, eine unterschiedliche Abfolge von Abbindestellen aufweisen und nicht nur in Bindefadenlängsrichtung zueinander versetzt liegen, grundsätzlich aber dann die gleiche Abfolge von Abbindestellen bzw. das gleiche Muster der Einbindung in die Grundbindungen aufweisen.In a variant which is advantageous with regard to the simplest possible construction of the binding pattern, it is further proposed that in a binder thread repeat the number of pairs of binder threads having mutually different courses of the binding threads forming them is smaller than the number of binding thread pairs present in a binder thread repeat. Here, too, binding threads with a different course are distinguished by the fact that with respect to the basic weave or fabric layers with which they Form binding segments, have a different sequence of bonding sites and not only in the binding thread longitudinal direction offset from each other, but in principle then have the same sequence of bonding sites or the same pattern of involvement in the basic bonds.
Um insbesondere in der ersten Gewebelage eine sehr hohe Gleichmäßigkeit der Bindungsstruktur bereitstellen zu können, wird vorgeschlagen, dass die Bindefäden eines Bindefadenpaares in der ersten Gewebelage einen die Bindung der ersten Gewebelage fortsetzenden scheinbaren Grundbindungsfaden der ersten Gewebelage bilden.In order to be able to provide a very high uniformity of the bonding structure, in particular in the first fabric layer, it is proposed that the binding threads of a pair of binder threads in the first fabric layer form an apparent ground weave thread of the first fabric layer continuing the binding of the first fabric layer.
Weiter kann vorgesehen sein, dass eine Rapportlänge der Bindefäden in Bindefadenrichtung größer ist, als eine Rapportlänge der Grundbindung der ersten Gewebelage oder/und der zweiten Gewebelage in Bindefadenrichtung.It can further be provided that a repeat length of the binding threads in the binding thread direction is greater than a repeat length of the plain weave of the first fabric layer and / or the second fabric layer in the binding thread direction.
Die Erfindung betrifft ferner eine Maschine zur Herstellung von Bahnmaterial, insbesondere Papier oder Karton, welche wenigstens ein erfindungsgemäß ausgestaltetes Gewebeband umfasst.The invention further relates to a machine for producing web material, in particular paper or cardboard, which comprises at least one fabric tape designed according to the invention.

Um einen Verbund zwischen den beiden Gewebelagen 114, 116 vorzusehen, sind in einem jeweiligen Bindefadenrapport insgesamt zehn Paare von Bindefäden vorhanden. Diese einander jeweils paarweise zugeordneten Bindefäden i1-i2, i3-i4, i5-i6, i7-i8, i9-i10, i11-i12, i13-i14, i15-i16, i17-i18 und i19-i20 liegen jeweils in Kettrichtung unmittelbar nebeneinander. Die Bindefäden eines jeweiligen Bindefadenpaares wechseln zwischen den beiden Gewebelagen 114, 116, so dass sich beim Bindefadenpaar i1-i2 beispielsweise unter den Kettfäden 11, 18, 25, 35 und 45 Wechselstellen der Bindefäden i1, i2 ergeben.In order to provide a bond between the two
Die Bindefäden der jeweiligen Bindefadenpaare sind so in die erste Gewebelage 114 eingebunden, dass sie dort die Grundbindung, also die Leinwandbindung, fortsetzen. Insbesondere erkennt man, dass auch durch den mehrfachen Wechsel der Bindefäden zwischen den einzelnen Gewebelagen 114, 116 in einem Bindefadenrapport die beiden Bindefäden eines jeweiligen Bindefadenpaares in der ersten, also papierseitigen Gewebelage 114 einen in die erste Gewebelage 114 eingebundenen und scheinbar durchlaufenden fiktiven Grundbindungsfaden bilden.The binding threads of the respective binder thread pairs are integrated into the
Jeder der Bindefäden i1 bis i20 eines Bindefadenrapports bildet sowohl in der ersten Gewebelage 114 als auch in der zweiten Gewebelage 116 jeweils mehrere Bindesegmente S1, S2. Ein Bindesegment ist dabei jeweils gebildet durch einen Abschnitt des betroffenen Bindefadens, in welchem dieser in einer jeweiligen Gewebelage 114 oder 116 über zumindest einen, ggf. auch mehrere und nicht notwendigerweise unmittelbar benachbarte Kettfäden abbindet. So bildet beispielsweise der Bindefaden i1 des obersten Bindefadenpaares i1-i2 in
In der zweiten Gewebelage 116 sind ebenfalls Bindesegmente S2 gebildet, wobei beispielsweise der erste Bindefaden i1 ein Bindesegment S2 mit den Kettfäden 14, 17 bildet. Ein weiteres Bindesegment bindet dieser Bindefaden i1 mit den Kettfäden 27, 29. Hier umfassen also die Bindesegmente ebenfalls mehrere Kettfäden, insbesondere jeweils zwei unmittelbar nebeneinander liegende Kettfäden, so dass bei jedem Bindesegment S2 der Bindefaden i1, und gleichermaßen auch der Bindefaden i2 an der Laufseite über zwei Kettfäden flottiert.Binder segments S 2 are also formed in the

Die
Die Anordnung der Bindesegmente S2 in der zweiten Gewebelage 116 ist derart gewählt, dass diese Bindesegmente S2 entlang von Bindesegmentdiagonalen D angeordnet sind. Diese Bindesegmentdiagonalen D verlaufen sowohl schräg zur Kettrichtung als auch schräg zur Schussrichtung. Man erkennt, dass innerhalb eines Bindefadenrapportes eine Mehrzahl im Wesentlichen parallel zueinander verlaufender Bindesegmentdiagonalen D existiert, entlang welchen die Bindesegmente S2 der zweiten Gewebelage 116 aufeinander folgend angeordnet sind.The arrangement of the binding segments S 2 in the
Es hat sich gezeigt, dass durch das Bereitstellen derartiger Bindesegmentdiagonalen D, entlang welchen die Bindesegmente S2 der zweiten Gewebelage 116 bevorzugt angeordnet sind, in der zweiten Gewebelage 116 eine von einer vollkommen willkürlichen Verteilung der Bindesegmente S2 abweichende Regelmäßigkeit erzielt wird, die wiederum eine Markierungsneigung zur Folge hat. Insbesondere kann damit die bei willkürlicher Positionierung entstehende Clusterbildung vermieden werden.It has been found that by providing such binding segment diagonal D, along which the binding segments S 2 of the

Obgleich hier also eine etwas größere Unregelmäßigkeit vorhanden ist, da mehrere verschiedene Arten von Diagonalen in einem Bindefadenrapport existieren, ist innerhalb der einzelnen Diagonalen D, D' und D" wieder für vergleichsweise hohe Regelmäßigkeit gesorgt.Thus, although there is a somewhat greater irregularity since there are several different types of diagonals in a binder thread repeat, comparatively high regularity is again provided within the individual diagonals D, D 'and D ".

Insbesondere erkennt man, dass bei ein- und demselben Bindefadenpaar, beispielsweise den Bindefäden i3 und i4 zwischen zwei Wechselstellendiagonalen Dw der ersten Art, zwei Wechselstellen W, Wv liegen können, wovon eine beispielsweise auf der Wechselstellendiagonale Dw' der zweiten Art liegt, beispielsweise die am Kettfaden 10 gebildete Wechselstelle W, während eine andere als versetzte Wechselstelle Wv, also beispielsweise die am Kettfaden 16 gebildete Wechselstelle, versetzt liegt. Diese zusätzlichen Wechselstellen bzw. versetzten Wechselstellen Wv könnten letztendlich auch als eine weitere Diagonale der zweiten Art definierende Wechselstellen betrachtet werden.

Aufgrund dieser größeren Anzahl und der unterschiedlichen Art von Bindesegmenten ergibt sich wieder eine Ausrichtung der Bindesegmente entlang von Bindesegmentdiagonalen, wobei hier eine größere Anzahl von Diagonalen D, D', D" und D'" in einem Bindefadenrapport auftritt. Man erkennt, dass die Bindesegmente unterschiedlicher Diagonalen sich beispielsweise in Kettrichtung fortgesetzt berühren können, also in Kettrichtung nebeneinander liegen können. In den einzelnen Diagonalen ist eine hohe Regelmäßigkeit in der Abfolge der dort angeordneten Bindesegmente vorhanden. Insbesondere erkennt man auch, dass in der Bindesegmente verschiedener Art umfassenden Bindesegmentdiagonale D"' jeweils eine alternierende Abfolge eines Bindesegments, welches nur einen Kettfaden umfasst, und eines Bindesegments, welches zwei Kettfäden umfasst, mit einer dann folgenden Trennung von einem Kettfaden vorhanden ist.Because of this larger number and the different type of binding segments, the binding segments are again aligned along binding segment diagonals, with a larger number of diagonals D, D ', D "and D'" occurring in a binding thread repeat. It can be seen that the binding segments of different diagonals can, for example, continue to touch each other in the warp direction, ie they can lie next to one another in the warp direction. In the individual diagonals there is a high degree of regularity in the sequence of the binding segments arranged there. In particular, it can also be seen that binding segment diagonal D "'comprising binding segments of various types in each case has an alternating sequence of a binding segment comprising only one warp thread and a binding segment comprising two warp threads with a subsequent separation from a warp thread.

Bindefadenpaare, eine sehr hohe Regelmäßigkeit bereitgestellt ist, während in der zweiten Gewebelage grundsätzlich zwar auch durch das Anordnen der dort gebildeten Bindesegmente S2 entlang der Bindesegmentdiagonalen für eine gewisse Regelmäßigkeit gesorgt ist.

Die erfindungsgemäße Ausgestaltung mit dem Anordnen von in der laufseitigen Gewebelage vorhandenen Bindesegmenten entlang jeweiliger Bindesegmentdiagonalen kann selbstverständlich auch Anwendung finden, wenn die Bindefäden sich in Kettrichtung erstreckend ausgebildet sind. Ferner ist es möglich, sowohl in Kettrichtung, als auch in Schussrichtung verlaufende Bindefäden vorzusehen, wobei dann sowohl für die in Kettrichtung verlaufenden Bindefäden, als auch die in Schussrichtung verlaufenden Bindefäden die vorangehend angegebene Positionierung jeweiliger Bindesegmente realisiert bzw. einander überlagert sein kann. Weiter ist darauf hinzuweisen, dass bei einem Gewebeband für eine Maschine zur Herstellung von Bahnmaterial die Bindefäden unabhängig davon, ob sie als Schussfäden oder Kettfäden ausgebildet sind, in Maschinenrichtung, also der Bandlaufrichtung sich erstreckend ausgebildet sein können, oder in Quermaschinenrichtung, also quer zur Bandlaufrichtung sich erstreckend ausgebildet sein können.The embodiment according to the invention with the arrangement of existing in the running side fabric layer binding segments along respective Tie diagonal can of course also apply when the binding threads are formed extending in the warp direction. Furthermore, it is possible to provide binding yarns running both in the warp direction and in the weft direction, in which case the above-mentioned positioning of respective binding segments can be realized or superimposed on one another both for the binding threads extending in the warp direction and for the binding threads running in the weft direction. It should also be pointed out that, in the case of a fabric band for a machine for producing web material, the binding threads can be designed to extend in the machine direction, ie the band running direction, irrespective of whether they are weft threads or warp threads, or in the cross machine direction, ie transversely to the band running direction may be formed extending.
Weiter ist vorgesehen, dass, obgleich vorangehend ausschließlich Ausgestaltungsbeispiele mit zwei Gewebelagen beschrieben wurden, die Erfindung auch Anwendung finden kann bei Gewebebändern mit mehr als zwei Gewebelagen, also beispielsweise drei Gewebelagen. So kann zwischen der die Oberfläche zur Aufnahme des zu fertigenden Bahnmaterials bereitstellenden ersten Gewebelage und der die Rückseite zur Auflage auf den verschiedenen Antriebs- oder Umlenkwalzen bereitstellenden, laufseitigen zweiten Gewebelage eine dritte Gewebelage angeordnet sein. Die den Zusammenhalt der verschiedenen Gewebelagen bereitstellenden Bindefäden können sich durch alle diese Gewebelagen hindurch erstrecken, also dann wiederum Bindesegmente sowohl in der ersten Gewebelage, als auch der zweiten Gewebelage und dann auch der dritten Gewebelage bilden. Grundsätzlich können aber auch die die vorangehend ausführlich diskutierten Bindesegmente in der zweiten Gewebelage bildenden Bindefäden, die zweite Gewebelage direkt mit der dritten Gewebelage verbinden. Es können weiters noch zusätzliche Bindefäden oder Bindefadenpaare vorgesehen sind, welche eine Anbindung der ersten Gewebelage an die dritte Gewebelage realisieren.It is further contemplated that, although previously only embodiments with two layers of fabric have been described, the invention may also find application in fabric strips having more than two layers of fabric, for example, three layers of fabric. Thus, a third fabric layer can be arranged between the first fabric layer which provides the surface for receiving the web material to be produced and the second fabric fabric side which provides the reverse side for support on the various drive or deflection rollers. The binding threads which provide the cohesion of the various fabric layers can extend through all of these fabric layers, ie in turn form binding segments both in the first fabric layer and the second fabric layer and then also the third fabric layer. In principle, however, the binding segments forming binding threads in the second fabric layer which previously discussed in detail can also connect the second fabric layer directly to the third fabric layer. Furthermore, additional binding threads or pairs of binder threads may be provided, which realize a connection of the first fabric layer to the third fabric layer.
