Definitions
- the invention relates to a paper machine screen as a composite fabric, consisting of an upper or forming fabric and a lower or wear fabric with at least three sets of longitudinal threads and at least two sets of transverse threads.
- DE-OS 29 17 649 describes a forming fabric for paper machines, consisting of a first set of warp threads and a first set of weft threads, which are woven together to form a first complete fabric, and a second set of warp threads and a second set of weft threads that are woven together to form a second damplette fabric.
- the said first fabric and the second fabric are said to be special. binding weft threads located between the fabrics are bound together, which bind with threads from said first and second warp thread sets.
- the aim pursued there is to let the binding weft threads run fairly straight in the fabric body, whereby they are wrapped in warp threads of the upper and lower fabrics, whereby the binding points should lie in the fabric body and not on its outer threads and therefore do not affect the flatness of the paper side not achieved with this known sieve.
- the binding weft threads do not run straight, but are heavily cranked and form on the paper side of the screen with the weft threads of the upper fabric regularly arranged double offsets that draw depressions into the surface, which even include adjacent offsets.
- this does not eliminate the disadvantages mentioned at the outset, namely the strong markings, which are intolerable for many types of paper, in particular for fine papers.
- the object of the invention is therefore to design the paper machine screen of the type mentioned at the outset, which should preferably be used for the production of fine papers, in such a way that the marking problem is finally eliminated.
- the paper machine sieve according to the invention thus forms a composite fabric with double offsets.
- all the outer longitudinal cranks of the upper fabric are formed from the first and the second longitudinal thread set.
- the offset distribution of the upper fabric and / or the lower thread can correspond to a linen weave, and, according to a further embodiment of the invention, transverse threads can additionally be woven into the lower fabric, which span at least three longitudinal threads to the outside. These additionally woven cross threads can consist of a highly wear-resistant material.
- the lower fabric can also be woven in Batavia weave.
- first and second warp or longitudinal thread sets 1 and 2 are interwoven with the first weft or transverse thread set 4 to form a so-called simple weave, in which all outwardly shaped longitudinal cranks are formed from a warp thread 1 and a warp thread 2, as a result of which the exercise by them Pressure on the weft threads spanned by them is the same at all points. So there are no offsets that are exposed to increased tension and therefore no depressions in the forming fabric that could cause marks in the paper.
- the connection of the upper fabric and the lower fabric is made by the thread pairs 7 and 8, which alternately bind in the lower fabric.
- the threads 9 are not woven with the lower fabric, but could be replaced at any time by pairs of threads 7 and 8.
- FIGS. 2 and 2a show a preferred construction of a wear fabric to which a group of transverse threads 6 made of highly wear-resistant material has been incorporated. These wear threads 6 form long offsets spanning outward three longitudinal or warp threads and thus improve the weft properties of the wear fabric.
- cranks x of the forming fabric but also the cranks y of the wearing fabric are double cranks, the number of stitches of the forming fabric being four times as large as that of the wearing fabric. It is these cranks y that illustrate the extraordinarily high number of tie points.
- FIGS. 4 and 4a Such a combination is shown in FIGS. 4 and 4a.
- the wear fabric is woven in Batavia weave.
- the set of binding threads consists only of thread pairs 7 and 8.
- the number of binding threads is thus twice as large as the number of warp threads of the upper fabric. It even exceeds the total of all longitudinal or warp threads 1 and 3 of the two fabrics.
- the number of stitches is Forming fabric four times the size of wear fabric.
- the number of binding threads is always substantially smaller than the number of threads of the forming fabric running in the same direction, this number of binding threads in the fabric according to the invention is larger, for example, as explained above, twice as large.
- all of the offsets are on the outside the longitudinal or warp threads of the upper or forming fabric are double-woven, as a result of which all offsets of this fabric and not just a few are disturbed in the same way.
- This advantageously not only largely eliminates the marking, but also optimally distributes the entirety of the binding forces to a maximum of binding points, thereby reducing the load on the individual binding point to a minimum.

Abstract
Description
Die Erfindung betrifft ein Papiermaschinen-Sieb als Verbundgewebe, bestehend aus einem Ober- oder Formiergewebe und einem Unter- oder Verschleißgewebe mit wenigstens drei Längsfadensätzen sowie aus wenigstens zwei Querfadensätzen.The invention relates to a paper machine screen as a composite fabric, consisting of an upper or forming fabric and a lower or wear fabric with at least three sets of longitudinal threads and at least two sets of transverse threads.
Bisher bekanntgewordene Verbundgewebe als Papiermaschinen-Siebe konnten bis heute zur Herstellung von Feinpapieren aufgrund der mangelhaften Beschaffenheit der papierseitigen Oberfläche, die zu Markierungen aller Art im Papier führt, nicht erfolgreich eingesetzt werden. In diesem Zusammenhang sind Längsmarkierungen, Quermarkierungen und Diagonalmarkierungen bekanntgeworden, die so stark sind, daß die Siebe in den meisten Fällen aus der Papiermaschine herausgeschnitten werden mußten.To date, composite fabrics that have become known as paper machine screens have not been successfully used for the production of fine papers due to the poor quality of the surface on the paper side, which leads to all kinds of markings in the paper. In this connection, longitudinal markings, transverse markings and diagonal markings have become known which are so strong that in most cases the sieves had to be cut out of the paper machine.
In der DE-OS 29 17 649 ist ein Formiersieb für Papiermaschinen beschrieben, bestehend aus einem ersten Satz Kettfäden und einem ersten Satz Schußfäden, die miteinander zu einem ersten kompletten Gewebe zusammengewebt sind, und aus einem zweiten Satz Kettfäden sowie einem zwiten Satz Schußfäden, die miteinander zu einem zweiten dampletten Gewebe verwoben sind. Das genannte erste Gewebe sowie das zweite Gewebe sollen dabei durch besondere. zwischen den Geweben gelegene Bindeschußfäden zusammengebunden werden, die mit Fäden aus den genannten ersten und zweiten Kettfädensäzen einbinden. Das dort angestrebte Ziel, die Bindeschußfäden ziemlich gerade im Gewebekörper verlaufe zu lassen, wobei sie von Kettfäden des oberen und des unteren Gewebes umschlungen werden, wodurch die Bindepunkte im Gewebekörper und nicht an dessen Außenfäden liegen sollen und deshalb die Ebenheit der Papierseite nicht beeinflussen, wird bei diesem bekannten Sieb jedoch nicht erreicht. Die Bindeschußfäden verlaufen nicht gerade, sondern sind stark gekröpft und bilden auf der Papierseite des Siebes mit den Schußfäden des Obergewebes regelmäßig angeordnete Doppelkröpfungen, die in die Oberfläche Vertiefungen hineinziehen, welche sogar noch benachbarte Kröpfungen umfassen. Dadurch werden aber die eingans genannten Nachteile, nämlich die starken Markierungen, die für viele Papiersorten, insbesondere für Feinpapieer ,untragbar sind, nicht beseitigt.DE-OS 29 17 649 describes a forming fabric for paper machines, consisting of a first set of warp threads and a first set of weft threads, which are woven together to form a first complete fabric, and a second set of warp threads and a second set of weft threads that are woven together to form a second damplette fabric. The said first fabric and the second fabric are said to be special. binding weft threads located between the fabrics are bound together, which bind with threads from said first and second warp thread sets. The aim pursued there is to let the binding weft threads run fairly straight in the fabric body, whereby they are wrapped in warp threads of the upper and lower fabrics, whereby the binding points should lie in the fabric body and not on its outer threads and therefore do not affect the flatness of the paper side not achieved with this known sieve. The binding weft threads do not run straight, but are heavily cranked and form on the paper side of the screen with the weft threads of the upper fabric regularly arranged double offsets that draw depressions into the surface, which even include adjacent offsets. However, this does not eliminate the disadvantages mentioned at the outset, namely the strong markings, which are intolerable for many types of paper, in particular for fine papers.
Durch die US-PS 3 127 308 ist nun zwar ein Formiersieb bekanntgeworden, das eine feinmaschige Seite nach der Papierbahn und eine grobmaschige Seite als Verschleißseite hat, die in Form von kompletten Geweben vorliegt, welche mit besonderen Bindekettfäden zusammenbinden, jedoch werden bei dieser bekannten Konstruktion keine Angaben über die Verteilung der Bindungspunkte und deren Einfluß auf die Papierseite des Siebes gemacht, so daß davon auszugehen ist, daß auch bei diesem bekannten Sieb der wellenförmige Verlauf der Kettfäden auf der Papierseite zu den genannten nachteiligen Markierungen führen wird.Through the US-
Die Aufgabe der Erfindung besteht deshalb darin, das Papiermaschinen-Sieb der eingangs genannten Art, das vorzugsweise zur Herstellung von Feinpapieren Verwendung finden soll, so auszubilden, daß das Markierungsproblem endgültig beseitigt wird.The object of the invention is therefore to design the paper machine screen of the type mentioned at the outset, which should preferably be used for the production of fine papers, in such a way that the marking problem is finally eliminated.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß wenigstens die Hälfte aller außen liegenden Längskröpfungen des Obergewebes (Papierseite) des Siebes aus Längsfadensätzen 1 und 2 gebildet sind, und daß der erste Längsfadensatz 1 mit dem ersten Querfadensatz 4, der dritte Längsfadensatz 3 mit dem zweiten Querfadensatz 2 und wenigstens Teile des zweiten Längsfadensatzes 2 mit beiden Querfadensätzen 4 und 5 verwoben sind.This object is achieved in that at least half of all outer longitudinal cranks of the upper fabric (paper side) of the sieve are formed from longitudinal thread sets 1 and 2, and that the first longitudinal thread set 1 with the first transverse thread set 4, the third longitudinal thread set 3 with the second transverse thread set 2 and at least parts of the second longitudinal thread set 2 are interwoven with both
Somit werden beim erfindungsgemäßen Sieb möglichst viele aber wenigstens die Hälfte aller außen liegenden Kröpfungen der Längsfäden des Obergewebes und damit der Papierseite doppelt gewoben. Dadurch werden wenigstens die Hälfte aller Kröpfungen des Obergewebes und nicht nur einzelne in gleicher Weise gestört.Thus, as many as possible, but at least half of all external cranks of the longitudinal threads of the upper fabric and thus of the paper side are woven twice in the sieve according to the invention. As a result, at least half of all bends in the upper tissue and not just some are disturbed in the same way.
Das erfindungsgemäße Papiermaschinen-Sieb bildet somit ein Verbundgewebe mit Doppelkröpfungen. Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind alle außen liegenden Längskröpfungen des Obergewebes aus dem ersten und dem zweiten Längsfadensatz gebildet. Ferner ist die vorteilhafte Möglichkeit gegeben, alle Fäden des zweiten Querfadensatzes mit Fäden des zweiten Längsfadensatzes zu verweben. Die Gesamtheit der Bindekräfte wird auf ein Maximum von Bindepunkten verteilt, die Belastung des einzelnen Bindepunktes dadurch auf ein Minimum reduziert.The paper machine sieve according to the invention thus forms a composite fabric with double offsets. According to an advantageous embodiment of the invention, all the outer longitudinal cranks of the upper fabric are formed from the first and the second longitudinal thread set. Furthermore, there is the advantageous possibility of interweaving all threads of the second set of transverse threads with threads of the second set of longitudinal threads. The totality of the binding forces is distributed over a maximum of binding points, the load on the individual binding point is thereby reduced to a minimum.
Die Kröpfungsverteilung des Obergewebes und/oder des Untergewehes kann einer Leinenb indung entsprechen, und in das Untergewebe können, gemäß einer weiteren Ausgestaltung der Erfindung, zusätzlich Querfäden eingewoben sein, die nach außen wenigstens drei Längsfäden überspannen. Diese zusätzlich eingewobenen Querfäden können aus einem hochverschleißfesten Material bestehen.The offset distribution of the upper fabric and / or the lower thread can correspond to a linen weave, and, according to a further embodiment of the invention, transverse threads can additionally be woven into the lower fabric, which span at least three longitudinal threads to the outside. These additionally woven cross threads can consist of a highly wear-resistant material.
Des weiteren hat sich bewährt, wenigstens einen Teil des zweiten Längsfadensatzes aus einem Material hoher Dehnung herzustellen und den Durchmesser der Fäden des zweiten Längsfadensatzes höchstens 3/4 des Durchmessers der Fäden des ersten Längsfadensatzes auszulegen.Furthermore, it has proven useful to produce at least part of the second longitudinal thread set from a material of high elongation and to design the diameter of the threads of the second longitudinal thread set at most 3/4 of the diameter of the threads of the first longitudinal thread set.
Ferner kann das Untergewebe auch in Batavia-Bindung gewoben sein.The lower fabric can also be woven in Batavia weave.
Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. In der Zeichnung zeigt:

- 1 and 1a plan view and longitudinal sectional view of a composite fabric according to the invention from a fine forming fabric in linen weave and a coarse wear fabric in linen weave,
- 2 and 2a in plan view and sectional view of a composite fabric according to the invention with a wear fabric, in which a group of transverse threads made of highly wear-resistant material has been incorporated,
- 3 and 3a show a top view of the composite fabric according to the invention in two different fabric finenesses, the cranks x of the forming fabric and the cranks y of the wear fabric being double cranks and

Die Fig. 1 und 1a zeigen ein Verbundgewebe, das aus einem feinen Formiergewebe in Leinenbindung und einem groben Verschleißgewebe ebenfalls in Leinenbindung besteht. Die ersten und zweiten Kett- oder Längsfadensätze 1 und 2 sind mit dem ersten Schuß- oder Querfadensatz 4 zu einer sogenannten einfachen Bindung verwebt, bei der alle nach außen geformten Längskröpfungen aus einem Kettfaden 1 und einem Kettfaden 2 gebildet sind, wodurch der durch sie ausgeübte Druck auf die von ihnen überspannten Schußfäden an allen Stellen gleich ist. Es gibt also keine Kröpfungen, die einer erhöhten Spannung ausgesetzt sind, und somit keine Vertiefungen im Formiergewebe, die Markierungen im Papier verursachen könnten. Die Verbindung des Obergewebes und des Untergewebes wird durch die Fadenpaare 7 und 8 hergestellt, die abwechselnd im Untergewebe abbinden. Die Fäden 9 sind nicht mit dem Untergewebe verwebt, könnten aber jederzeit durch Fadenpaare 7 und 8 ersetzt werden.1 and 1a show a composite fabric, which consists of a fine forming fabric in linen weave and a coarse wear fabric also in linen weave. The first and second warp or longitudinal thread sets 1 and 2 are interwoven with the first weft or transverse thread set 4 to form a so-called simple weave, in which all outwardly shaped longitudinal cranks are formed from a warp thread 1 and a warp thread 2, as a result of which the exercise by them Pressure on the weft threads spanned by them is the same at all points. So there are no offsets that are exposed to increased tension and therefore no depressions in the forming fabric that could cause marks in the paper. The connection of the upper fabric and the lower fabric is made by the
Die Fig. 2 und 2a zeigen eine bevorzugte Konstruktion eines Verschleißgewebes, dem eine Gruppe Querfäden 6 aus hocherschleißfestem Material eingebunden wurde. Diese Verschleißfäden 6 bilden lange, nach außen drei Längs- oder Kettfäden überspannende Kröpfungen und verbessern so die Schußläufereigenschaften des Verschleißgewebes.2 and 2a show a preferred construction of a wear fabric to which a group of
In den Fig. 3 und 3a ist eine Ausführungsform gezeigt, bei der nicht nur die Kröpfungen x des Formiergewebes, sondern auch die kröpfungen y des Verschleißgewebes Doppelkröpfungen sind, wobei die Anzahl der Maschen des Formiergewebes viermal so groß ist wie beim Verschleißgewebe. Gerade diese Kröpfungen y verdeutlichen die außerordentlich hohe Zahl von Bindepunkten.3 and 3a show an embodiment in which not only the cranks x of the forming fabric, but also the cranks y of the wearing fabric are double cranks, the number of stitches of the forming fabric being four times as large as that of the wearing fabric. It is these cranks y that illustrate the extraordinarily high number of tie points.
Es ist natürlich auch möglich, mit dem erfindungsgemäßen Verbindungsprinzip Gewebe mit unterschiedlichen Bindungen miteinander zu kombinieren. Eine solche Kombination zeigen die Fig. 4 und 4a. Hierbei ist das Verschleißgewebe in Batavia-Bindung gewoben. Der Bindefadensatz besteht nur aus Fadenpaaren 7 und 8. Die Anzahl der Bindefäden ist somit doppelt so groß wie die Anzahl der Kettfäden des Obergewebes Sie übersteigt sogar die Summe aller Längs-oder Kettfäden 1 und 3 der beiden Gewebe auch hier ist die Anzahl der Maschen des Formiergewebes viermal so groß wie beim Verschleißgewebe.It is of course also possible to combine fabrics with different weaves with one another using the connection principle according to the invention. Such a combination is shown in FIGS. 4 and 4a. The wear fabric is woven in Batavia weave. The set of binding threads consists only of
Während also bei den bekannten Verbundgeweben der eingangs genannten Art die Anzahl der Bindefäden stets wesentlich kleiner ist als die Anzahl der in der gleichen Richtung verlaufenden Fäden des Formiergewebes, ist diese Bindefädezahl beim erfindungsgemäßen Gewebe größer, beispieielweise wie oben erläutert, doppelt so groß.So while in the known composite fabrics of the type mentioned, the number of binding threads is always substantially smaller than the number of threads of the forming fabric running in the same direction, this number of binding threads in the fabric according to the invention is larger, for example, as explained above, twice as large.
Somit werden beim erfindungsgemäßen Papiermaschinen-Sieb in bevorzugter Ausführung alle außen liegenden Kröpfungen der Längs- oder Kettfäden des Ober- oder Formiergewebes doppelt gewoben, wodurch alle Kröpfungen dieses Gewebes und nicht etwa nur einige wenige, in gleicher Weise gestört werden. Dadurch wird in vorteilhafter Weise nicht nu eine weitgehende Beseitigung der Markierung erreicht, sondern auch eine optimale Verteilung der Gesamtheit der Bindekräfte auf ein Maximum von Bindepunkten, wodurch die Belastung des einzelnen Bindepunktes auf ein Minimum reduziert wird.Thus, in the preferred embodiment of the paper machine sieve according to the invention, all of the offsets are on the outside the longitudinal or warp threads of the upper or forming fabric are double-woven, as a result of which all offsets of this fabric and not just a few are disturbed in the same way. This advantageously not only largely eliminates the marking, but also optimally distributes the entirety of the binding forces to a maximum of binding points, thereby reducing the load on the individual binding point to a minimum.
Es versteht sich, daß durch entsprechende Verwendung von Bindeschüssen auch alle außen liegenden, papierseitigen Schußkröpfungen zu Doppelkröpfungen gemacht werden können. Das hier beschriebene, erfindungsgemäße Bindungsprinzip wäre dann zwar um 90° gedreht zur Anwendung gelangt, jedoch mit der gleichen Wirkung, allerdings wäre in diesem Fall der Webaufwand größer.It goes without saying that, by appropriately using binding wefts, all outside, paper-side weft cranks can also be made into double cranks. The binding principle according to the invention described here would then have been used rotated by 90 °, but with the same effect, but in this case the weaving effort would be greater.
