Description

 Fabric tape for a fibrous web machine

The invention relates to a fabric tape which is suitable for use in a machine producing and / or processing a fibrous web, in particular a paper, board, tissue or nonwoven machine.

Tissue bands of the generic type comprise MD threads extending longitudinal threads which are interwoven with extending in the CMD direction transverse threads to form cross-hairs. Such fabric tapes are usually made flat woven. For use in a machine producing and / or processing a fibrous web, such originally flat fabric tapes are made endless at a fabric seam area, so that they can be operated in the machine as endless belts. Such a fabric seam area can be provided, for example, by longitudinal threads, which are woven back in the region of their longitudinal thread end sections and form seam loops. Such a fabric seam area may also be formed by longitudinal thread end sections of longitudinal threads which are joined together in pairs and often interweave along a common weaving path with common transverse threads to form a seam fabric which is often identical to the flat woven fabric portion with transverse threads.

The tensile strength of the seam in the weave loops as well as in the fabric seam areas provided by the seam fabric is interwoven by the number of transverse yarns with which the longitudinal yarn end portions are woven back together or by the number of transverse yarns with which the merged longitudinal yarn end portions are woven together following a common weaving path depends and increases with increasing number of transverse threads with which the longitudinal thread end sections are interwoven. By weaving back or through the common web path, however, physical properties, such as, for example, permeability, are often influenced in the tissue seam area, so that these physical properties in the tissue suture area are locally different and different to the remaining portion of the tissue band.

In order to achieve a high tensile strength on the one hand and not too great a change in the permeability on the other hand, it is proposed in the prior art to join the longitudinal threads in the region of their longitudinal thread end sections at intersections with transverse threads.

For example, it is known from US Pat. No. 8,062,480 and WO2012 / 1 13767 to connect the longitudinal and transverse threads at the crossing points by the action of laser energy. It has now been found that, in particular in the case of woven tapes with open and / or single-ply weave structure and / or with a weave structure with long floats of the longitudinal threads, the longitudinal thread end sections are often only loosely anchored in the fabric and the longitudinal thread end sections can thus at least partially easily come out of the fabric and in particular can overhang the underside facing the fibrous web and generally providing the web contact side or the underside facing the machine and generally providing the machine contact side. This can lead to the damage of the fibrous web transported on the fabric belt or to the splicing of the yarn ends and thus to the weakening of the fabric belt. It is thus the object of the present invention to reduce or prevent at least partial emergence of the longitudinal thread end sections and thus to fix the longitudinal thread end sections in the region of their thread ends in the tissue.

The object is achieved by a fabric band suitable for use in a machine producing and / or processing a fibrous web, with longitudinal threads extending in the MD direction which are interwoven with transverse threads extending in the CMD direction to form crosshairs. The fabric tape in this case has an upper side facing the fibrous web and a lower side facing the machine, as well as a fabric seam section. In which When viewed in their length, the longitudinal threads have two terminal longitudinal thread end sections with respective thread ends, wherein at least some of the longitudinal thread end sections in the woven fabric seam section are woven with woven fabric stitching transverse threads provided by a part of the transverse threads following a weaving path. In this case, the weaving path of at least some longitudinal thread end sections immediately before the thread end in the direction of the yarn end can be described as follows by interweaving with four immediately adjacent woven fabric transverse yarns;

 The respective longitudinal thread end section crosses a first and a second weave seam transverse thread, in particular when the longitudinal thread end section runs on the upper and / or lower side,

 Subsequently, the longitudinal thread end section continuously crosses a third weave seam cross thread on one side of the upper and lower side,

 Thereafter, the longitudinal thread end portion between the third weave seam transverse thread and a fourth fabric stitch transverse thread runs from the one side of top and bottom toward the other side of top and bottom without subsequently interweaving with the fourth or another fabric stitch cross thread such that the thread end is arranged in the region of the fourth woven-seam transverse thread. The fabric tape according to the invention is characterized in that in the weaving path at least some of the longitudinal thread end portions of the longitudinal thread end at the crosshairs with the third Gewebenaht cross thread is firmly bonded and / or at least one crosshairs with the first and / or second weave seam transverse thread is materially connected, provided the longitudinal thread end section continuously crosses the first and / or second woven fabric transverse thread on the upper or lower side.

According to the invention, it is accordingly provided that the weaving path of at least some longitudinal thread end sections is guided immediately in front of the thread end such that the longitudinal thread end section is guided between two transverse threads, namely the third and fourth weave transverse threads, from one side to the other side of the fabric band and at least before one of the webpath namely, at least one transverse thread of first, second or third weave seam cross thread is connected in a materially joined manner.

Due to this special guidance of the weaving path and the special cohesive connection in front of the "change point" of the thread end section from one side to the other side of the fabric belt, a coming out of the longitudinal thread end section can be significantly reduced or even prevented.

A first and a second thread are interwoven within the meaning of the present invention, when the first thread crosses the second thread on one side continuously and the first thread before and after the second thread each at least one further thread on one side opposite one side crosses. In this case, the at least one further thread need not be arranged directly adjacent to the second thread.

It is further to be noted that the terms first, second, third and fourth weave stitch transverse threads always refer to the weaving path of the respective longitudinal thread end portion. Accordingly, the first to fourth fabric stitched transverse threads of the weaving path of one longitudinal thread end portion may be provided at least in part by other woven fabric transverse threads than the first to fourth woven fabric transverse threads of the weaving path of another longitudinal thread end portion. It is also conceivable that the first to fourth weave seams of the weaving path of one longitudinal thread end portion are provided by the same woven fabric side cross-threads as the first to fourth weave seam transverse threads of the weaving path of another longitudinal thread end portion.

The solution according to the invention thus comprises weaving paths in which i) the longitudinal thread end section on one side of the top and bottom continuously crosses the first to third weave seam transverse threads and is integrally bonded to at least one of the first to third weave seam transverse threads, wherein the Longitudinal thread end portion between the third and fourth weave seam transverse thread is guided from one to the other side;

ii) the longitudinal thread end portion on the other side of the top and bottom continuously crosses the first and second fabric stitched transverse threads, then between the second and third weave seam transverse thread is guided to one side and then on the one side continuously crosses the third weave seam transverse threads and is integrally bonded to at least one of the first to third weave seam transverse threads, wherein the longitudinal thread end portion between the third and fourth woven fabric cross-thread led from one side to the other;

iii) the longitudinal thread end portion on the other side of the top and bottom continuously crosses the first fabric stitched transverse thread, then is guided to one side between the first and second fabric stitched transverse thread and then continuously crosses the second and third fabric stitching transverse threads on one side and being integrally bonded to at least one of the first to third woven-fabric transverse threads, the longitudinal-thread-end portion being guided between the third and fourth woven-fabric transverse threads from one to the other side;

iv) the longitudinal thread end portion on one side of the top and bottom continuously crosses the first weave seam transverse thread, then between the first and second

Tissue seam transverse thread is guided to the other side, then continuously on the other side crosses the second weave seam transverse threads, subsequently guided between the second and third weave seam transverse thread to one side with at least one of the first to third weave seam transverse threads is materially connected wherein the longitudinal thread end portion is guided between the third and fourth woven fabric transverse threads from one to the other side.

In the context of this invention, the terms "intersection" and "crosshairs" are to be understood as synonymous.

Advantageous embodiments and further developments of the invention are specified in the subclaims.

Preferably, in the weaving path at least some longitudinal thread end sections, in particular all longitudinal thread end sections, the respective longitudinal thread end section is adhesively connected to at least two of the first, second and third weave seam transverse threads at the respective thread crossing point. It is conceivable in this context, for example, that the at least some longitudinal thread end sections are integrally connected to the third and the first weave seam of their respective weaving path. But it is also conceivable, for example, that at least some thread sections are materially connected to the third and the second weave seam transverse thread of their respective Webpfads.

Preferably, the upper side provides the web contacting side engageable with the fibrous web, and the lower surface provides the machine contact side engageable with the machine.

Preferably, all of the longitudinal thread end portions have a weaving path respectively comprising the first, second, third and fourth weave seam transverse threads.

Preferably, in the weaving path of all the longitudinal thread end sections, one side of the upper and lower side is the upper side and the other side of the upper side and lower side is the underside. As a result, all thread ends are guided on the underside. This makes uniform processing of the tissue band possible on only one side.

The solution according to the invention can be used in particular for a fabric band which is formed by only one system of longitudinal threads and / or by only one system of transverse threads, since in such fabrics without the solution according to the invention, the longitudinal thread end section can emerge particularly frequently.

The solution according to the invention can additionally and / or alternatively preferably be used with woven tapes which have a "relatively open" weave structure, Accordingly, according to one embodiment of the invention, it may be a fabric taping having a thread density in the range from 30 to 60 longitudinal threads per inch. in particular 40 to 55 longitudinal threads per inch and / or a thread density in the range 30 to 60 cross threads per inch, in particular 40 to 55 cross threads per inch has.

The fabric tape according to the invention is preferably a fabric tape having a permeability in the range of 450 to 850 cfm, in particular 450 to 750 cfm and / or a thickness in the range of 0.5 to 2 millimeters. Furthermore, the fabric tape is preferably a dryer fabric, in particular suitable for use in a drying device in which the wire is flowed through with hot air. Such a dryer fabric is commonly referred to as a "through air dryer" screen or TAD screen. According to a specific embodiment of the invention can be provided that the weaving end of each Langsfadenendabschnitte the respective thread end is disposed within the fabric or on the other side of the top and bottom.

According to one embodiment of the invention, it is provided that, in the weaving path of all longitudinal thread end sections, the longitudinal thread end section is woven after passing to the other side of the upper and lower side with no further woven fabric transverse thread.

There are various ways for producing the cohesive connection conceivable. According to a particularly preferred embodiment of the invention, it is provided that the cohesive connection is effected by the action of radiant energy of a specific wavelength or a specific wavelength range, in particular by laser radiation energy. Such a way of producing a cohesive connection has the advantage that it can be acted on very locally without applying the entire fabric band, for example, with temperature. It is conceivable in this context in particular that the wavelength or the wavelength range is in the infrared, in particular in the range of 700 nm to 1200 nm.

Specifically, it is conceivable that at least some cohesively connected threads before exposure to the radiation energy at the crosshairs between the threads, a material was introduced, which absorbs the radiation energy stronger than the material of the threads. Such an "absorber material" may, for example, be in liquid form and be sprayed between the parts to be joined, Such a liquid "absorber material" is sold, for example, under the name "Clearweld" from Gentex Corp. Alternatively, it is conceivable in that the first thread type is made of a material which absorbs the radiation energy more strongly than the material of the second thread type. and / or woven fabric transverse threads of a material comprising carbon black and / or colored pigments and / or carbon nanotubes (CNT). It is conceivable in this connection, in particular, that at least some woven-seam transverse threads are threads of the first type of thread.

It is also conceivable that at least some longitudinal threads are threads of the first type of thread. According to a preferred embodiment of the invention, it is provided that, in at least some of the longitudinal thread end sections, in particular in all longitudinal thread end sections, the longitudinal thread end section on one side of the top and bottom continuously crosses the second and the third weave seam transverse thread and at least with the second and / or third weave seam transverse thread is connected cohesively at the crosshairs. By this embodiment, a material connection with the second and / or third weave seam transverse thread is possible, wherein the action of the radiation energy for producing the cohesive connection can be made from a single page. This considerably facilitates and simplifies the production of the fabric tape according to the invention, in particular if the weaving paths of all longitudinal thread end portions are designed in this way.

In this context, in the weaving path of at least some of the longitudinal thread end sections, the second and / or third weaving thread transverse threads are threads of the first thread type, the longitudinal threads being threads of the second thread type, in this case for producing the cohesive connection the effect of the radiation energy on the one side done from top and bottom.

If at least some of the longitudinal threads are threads of the first type of thread, wherein the transverse threads are threads of the second type of thread, in this case for producing the integral connection between the respective longitudinal thread end section and the second and / or third weave seam transverse thread, the effect of the radiation energy on the other side done from top and bottom.

According to one possible specific embodiment of the invention, the fabric band is an endless fabric band, which is formed by a flat-woven full-tissue section and the fabric seam section. Here is the Full-tissue section formed by the longitudinal threads and by interwoven with the longitudinal threads full-tissue transverse threads, wherein the solid-fabric transverse threads are provided by the other part of the transverse threads. In addition, the full-thickness fabric section is delimited in its longitudinal extent by a first and a second end-side section end, wherein at least some, in particular all, of the longitudinal threads each have first and second longitudinal thread end sections provided by their two terminal longitudinal thread end sections. Here, the first longitudinal-thread end portion protrudes in the MD direction beyond the first end-side section end of the solid-tissue section, and the second longitudinal-thread end section projects beyond the second end-side section end in the MD direction. In such an endless fabric tape, the two end portion ends of the full-weave portion are joined together by the fabric sewing portion formed by joining the first and second longitudinal thread end portions and weaving them with woven-fabric transverse threads. It should also be noted in this connection that each first longitudinal thread end section is closed by a first thread end and each second longitudinal thread end section by a second thread end. A development of the invention based on the previous embodiment provides, in particular, that the fabric tape is endless, in that in each case a first and a second longitudinal thread end section are brought together in pairs, forming so-called "meeting points".

In this case, the paired first and second longitudinal thread end sections can each be the first and second longitudinal thread end section of one and the same longitudinal thread.

A further concrete development of the invention may provide that at least some of the paired first and second longitudinal thread end sections are woven together with one or more woven fabric transverse threads. When paired first and second longitudinal yarn end portions are interwoven together with one or more woven fabric transverse yarns, the length of a joint is determined by the number of fabric seam transverse yarns with which the gathered longitudinal yarn end portions are interwoven together. At the common Interweaving, the longitudinal thread end sections, which are brought together in pairs, follow in particular in each case the same weaving path.

It should be noted in this connection that the joint weaving preferably takes place with a maximum of ten woven-seam transverse threads, preferably with a maximum of four woven-seam transverse threads. It is also conceivable, however, that the longitudinal thread end sections, which are brought together in pairs, are not interwoven with any common woven-seam transverse thread.

If at least some of the paired first and second longitudinal thread end sections are woven together with at least one woven seam transverse thread, then it is conceivable that the at least one jointly interwoven woven fabric weave transverse thread in the weaving path of the first longitudinal thread end section and in the weaving path of the second thread section at least the third weave seam weave Querfaden bereitstellt.

A development of the invention provides that at least some of the paired first and second longitudinal thread end sections are woven together with a maximum of two directly adjacent woven fabric transverse threads. In this case, in the weaving path of the first longitudinal yarn end portion, one of the two woven fabric joint transverse yarns provides the second woven fabric transverse yarn and the other of the two interwoven fabric joint transverse yarns the third woven fabric transverse yarn, and one of the second longitudinal yarn end portion in the weaving path both commonly woven fabric stitched transverse threads provide the third fabric stitched transverse thread and the other of the two interwoven fabric stitching transverse threads provide the second woven fabric stitched transverse thread. Concretely, the weave seam section may be woven in a weave pattern having a longitudinal thread and a transverse thread repeat, wherein the longitudinal thread repeat is formed by equal to or more web seam transverse threads than the number of fabric stitching transverse threads with which the paired first and second longitudinal thread end sections are woven together. By such a relatively short weaving of the merged longitudinal thread end sections with common woven-seam transverse threads vary physical properties, such as permeability, less locally in the woven-seam region than when the common-weave extends over more woven-fabric transverse threads than the longitudinal-thread repeat has woven-fabric transverse threads. Alternatively, the fabric stitching portion may be woven in a weave pattern having a longitudinal and a repeatable filament repeat, wherein the longitudinal filament repeat is formed by fewer fabric stitched transverse filaments than the number of fabric stitching transverse filaments with which the paired first and second longitudinal filament end portions are woven together. According to a further alternative embodiment, it is also conceivable that at least some of the paired first and second longitudinal thread end portions are interwoven with no common weave seam transverse thread, the fourth weave stitch transverse thread of the weaving path of the first longitudinal thread end portion and the fourth weaving thread transverse thread of the weaving path of the second Thread section either the same weave seam transverse thread or two immediately adjacent woven fabric transverse threads are. Also by this measure, a strong variation of the physical properties, such as the permeability or the flatness of the top and / or bottom, counteracted in Gewebenahtbereich, wherein it has been shown that a greater distance in the MD direction of the paired merged first and second longitudinal thread end portions, as described above, entails an adverse weakening of the woven fabric seam, as well as often a too large permeability difference at that location from other fabric portions. When paired first and second longitudinal yarn end portions are not interwoven with any woven-fabric transverse yarns, the length of a meeting is determined by the number of woven-fabric transverse yarns interposed between the two ends of the weaving paths of the two longitudinal yarn end portions being joined.

In order to increase the strength of the seam, it makes sense, if the places -Treffstellen- where the first and second Längsfadenendabschnitte in pairs are merged for different pairs in MD direction offset from each other.

Concretely, therefore, the third weave seam transverse threads in the weaving path of different first longitudinal thread end sections can be provided by different woven fabric transverse threads and / or the third woven fabric transverse threads in the weaving path of different second longitudinal thread end sections can be provided by different woven fabric transverse threads.

Specifically, the fabric seam transverse threads providing the third woven-fabric transverse threads in the weaving path respectively of adjacent first longitudinal thread end sections can be arranged offset from each other by at least one woven-fabric transverse thread, in particular at least one woven-fabric transverse thread between them. It is conceivable in this context, for example, that the third transverse seam threads in the weaving path respectively adjacent first Längsfadenendabschnitte providing tissue seam transverse threads are arranged offset from one another by a longitudinal thread repeat. Likewise, the fabric seam transverse threads providing the third woven fabric transverse threads in the weaving path respectively of adjacent first longitudinal thread end sections can be arranged offset from each other by at least one longitudinal thread repeat.

Preferably, in this connection, the woven-fabric transverse yarns to which a first pair of merged first and second longitudinal yarn end portions are interwoven together comprise a plurality of woven-fabric transverse yarns offset from the woven-fabric transverse yarns to which a pair of first and second longitudinal yarn end portions immediately adjacent to the first pair are common are interwoven. If, in this connection, the threads of the first type are provided by woven-transverse threads, then the possibility is created that the threads of the first type entering into the first pair with a cohesive connection are arranged spaced apart from the threads of the first type entering into a cohesive connection with the second pair , As a result, the rigidity of the tissue band in the MD direction can be reduced since a material-locking connection takes place in strip-like areas spaced apart from each other in the MD direction. The invention will be further explained with reference to schematic drawings. It show the

FIGS. 2a to 2c show various embodiments of weaving paths of paired first and second longitudinal thread end sections 5a, 5b of a fabric tape according to the invention with a top side OS providing a web contact side and a underside US providing a machine contact side in the fabric seam region. The fabric tape is herein single layer, formed with a system of longitudinal threads and a system of transverse threads which are interwoven with the longitudinal threads. Each longitudinal thread of the fabric tape provides, viewed in its length, two terminal longitudinal thread end portions, namely, the first longitudinal thread end portion 5a and the second longitudinal thread portion 5b. In this case, the first longitudinal thread end section 5a is closed by the first thread end 6a and the second longitudinal thread end section 5b is closed by the second thread end 6b.

FIG. 2a shows the weaving path of two longitudinal thread end sections 5a, 5b of the fabric band in a region of the fabric seam section. The fabric tape is formed by a flat-woven full-weave portion, not shown, and the fabric sewing portion, the full-fabric portion being formed by the longitudinal yarns and all-fabric cross-threads provided by another part of the transverse yarns interwoven with the longitudinal yarns, and the full-thickness fabric portion is longitudinally stretched first and a second end portion end is limited. In the present case, for each longitudinal thread, its one-end first longitudinal thread end section 5a protrudes beyond the first end-side section end in the MD direction as its other end second longitudinal thread end section 5b projects beyond the second end-side section end of the full-tissue section in the MD direction. To the endless making of Tissue tapes, the first and second longitudinal thread end portions were each paired together and interwoven with the woven fabric cross-threads, whereby the two end-side portion ends are interconnected by the Gewebahahtabschnitt. First longitudinal thread end sections 5a and second longitudinal thread sections 5b are each brought together in pairs at a meeting point T and interwoven with woven fabric transverse threads. As can be seen from the illustration of FIG. 2a, the first longitudinal thread end section 5a and the second longitudinal thread end section 5b are woven in the area immediately in front of the respective thread end 6a, 6b with woven seam transverse threads A1.

In this case, the first yarn end section 5a weaves in the direction of Ra of its yarn end designated as the first yarn end 6a with the woven fabric cross threads I to D and ends with its first yarn end 6a on the underside US of the fabric tape between the woven fabric cross threads E and D. When looking at the first longitudinal thread end portion 5a, the woven fabric transverse thread G is the first woven fabric transverse yarn 1a, the woven fabric transverse yarn F is the second woven fabric transverse yarn 2a, the woven fabric transverse yarn E is the third woven fabric transverse yarn 3a, and the woven fabric transverse yarn D is the fourth Fabric stitched transverse thread 4a ready. Concretely, the first longitudinal thread end portion 5a on the underside US continuously crosses the first and second weave seams 1a, 2a of its weaving path, then between the second and third weave seams 2a, 3a of its weaving path to the top OS around the third weave seam 3a to cross on the top OS running and then to switch between the third and fourth weave seam transverse thread 3a, 4a from the top OS to the bottom US, so that the first thread end 6a without another weave seam cross-thread A to I to cross at the Underside US is arranged in the region of the fourth weave seam transverse thread 4a.

Furthermore, the second yarn end section 5b weaves in the direction Rb of its yarn end considered as the second yarn end 6b with the woven fabric transverse threads A to F and ends with its second yarn end 6b on the underside US of the fabric tape between the woven fabric transverse threads F and E. As seen in the second longitudinal thread end portion 5b, the woven fabric thread C is the first woven fabric thread A, the woven fabric thread D is the second woven fabric thread 2a, the woven fabric thread E is the third fabric thread 3a, and the woven fabric thread F is the fourth Fabric stitched transverse thread 4a ready. Concretely, the second longitudinal thread end portion 5b on the underside US continuously crosses the first and second fabric stitched transverse threads 1b, 2b of its weaving path then alternates between the second and third weaving seams 2b, 3b of its weaving path to the topside OS around the third fabric stitching transverse thread 3b to cross the top OS continuously to subsequently switch between the third and fourth fabric stitched transverse threads 3b, 4b from the top side OS to the bottom side US so that the second thread end 6a without another fabric stitch cross thread A to I to cross at the bottom US in Area of the fourth fabric stitching cross-thread 4b of his web path is arranged. It will thus be seen that the paired first and second longitudinal thread end portions 5a, 5b are interwoven with the woven fabric transverse thread E, with the woven fabric woven transverse thread E in the weaving path of the first longitudinal thread portion 5a and in the weaving path of the second longitudinal thread portion 5b forming the third weaving seam. Querfaden 3a, 3b provides. The length of the meeting point T is determined in this case by the weave seam cross thread E.

In this case, the first longitudinal thread end section 5a and the second longitudinal thread end section 5b are connected at the intersection 7 with the woven fabric cross-thread E by a material fit by the action of radiant energy. In the present case, the woven-thread transverse thread E is provided as a thread of the first type, ie the woven-thread transverse thread E is made of a material which absorbs the radiant energy more strongly than the material of the longitudinal threads, with its longitudinal thread end portions 5a, 5b and the material of other transverse threads.
