Abstract

Die Längsfäden sind an den vorderen und hinteren Gewebekanten unter Bildung von Schlaufen in das Gewebe zurückgewebt, wobei ein Teil der Schlaufen als über die Gewebekanten vorstehende Nahtschlaufen für eine Steckdrathverbindung ausgebildet sind. Damit die Krafteinleitung in den Gewebekörper günstiger ist und die Montage bei Zugbelastung erleichtert wird, sind sämtliche Nahtschlaufen (14, 15) U-förmig und zur Gewebekante hin offen ausgebildet.A machine clothing, in particular paper machine felt or wire, has a flat fabric, at least two-ply fabric, the longitudinal threads of which tie in the layers consisting of transverse threads to form offsets. The longitudinal threads are woven back into the fabric at the front and rear fabric edges to form loops, part of the loops being designed as seam loops protruding over the fabric edges for a plug-in wire connection. In order that the introduction of force into the fabric body is cheaper and the assembly is easier under tensile loads, all seam loops (14, 15) are U-shaped and open towards the fabric edge.

Description

Die Erfindung betrifft eine Maschinenbespannung, insbesondere Papiermaschinenfilz oder -sieb, mit einem als Flachgewebe hergestellten, zumindest zweilagigen Gewebe, dessen Längsfäden die aus Querfäden bestehenden Lagen unter Bildung von Kröpfungen einbinden und an den vorderen und hinteren Gewebekanten unter Bildung von Schlaufen in das Gewebe zurückgewebt sind, wobei ein Teil der Schlaufen als über die Gewebekanten vorstehende Nahtschlaufen für eine Steckdrahtnahtverbindung ausgebildet sind.The invention relates to a machine clothing, in particular paper machine felt or wire, with a flat fabric, at least two-ply fabric, the longitudinal threads of which incorporate the layers of transverse threads to form cranks and are woven back into the fabric at the front and rear fabric edges to form loops , wherein a part of the loops are designed as seam loops projecting over the fabric edges for a plug wire seam connection.

Für Papiermaschinenbespannungen werden vielfach als Flachgewebe hergestellte, zwei- oder mehrlagige Gewebe eingesetzt Solche Flachgewebe zeichnen sich dadurch aus, daß die einzelnen Lagen im wesentlichen von den Querfäden gebildet werden und jeder Längsfaden Querfäden aus allen Lagen unter Bildung von Kröpfungen einbindet. Ein solches Flachgewebe ist in der DE-PS 28 06 742 als Trägergewebe für ein Trockenfilztuch dargestellt.For paper machine clothing, flat or double-layer or multi-layer fabrics are often used. Flat fabrics of this type are distinguished by the fact that the individual layers are essentially formed by the transverse threads and each longitudinal thread integrates transverse threads from all layers with the formation of offsets. Such a flat fabric is shown in DE-PS 28 06 742 as a carrier fabric for a dry felt cloth.

Bei diesen Flachgeweben werden die beiden quer zu den Längsfäden verlaufenden Gewebekanten dadurch gebildet, daß die Längsfäden unter Bildung von Schlaufen in den Gewebekörper zurückgewebt werden, und zwar in die Ebene eines benachbarten Längsfadens, der so weit gekürzt ist, daß er mit seinem Ende auf die Stirnseite des zurückgewebten Längsfadenabschnittes trifft. Der zurückgewebte Längsfadenabschnitt wird dabei so eingebunden, daß er die Gewebebindung des verkürzten Längsfadens bis zur Gewebekante hin fortsetzt Ein Teil der Schlaufen wird so gebildet, daß sie ein gutes Stück über die Gewebekanten vorstehen. Sie bilden dann Nahtschlaufen für eine Steckdrahtnahtverbindung. Hierzu sind die Nahtschlaufen der einen Gewebekante im Verhältnis zu denen der anderen Gewebekante so angeordnet, daß sie beim Zusammenführen der Gewebekanten miteinander kämmend überlappen, so daß von ihnen ein Kanal zum Durchführen eines Steckdrahtes entsteht. Der Steckdraht bildet dann die Kupplung der beiderseitigen Gewebekanten, so daß eine endlose Maschinenbespannung entsteht.In the case of these flat fabrics, the two fabric edges running transversely to the longitudinal threads are formed by weaving the longitudinal threads back into the fabric body with the formation of loops, specifically in the plane of an adjacent longitudinal thread, which is shortened so far, that its end meets the end face of the backwoven longitudinal thread section. The backwoven longitudinal thread section is bound in such a way that it continues the weave of the shortened longitudinal thread up to the fabric edge. A part of the loops is formed so that they protrude a good distance over the fabric edges. They then form seam loops for a plug wire seam connection. For this purpose, the seam loops of the one fabric edge are arranged in relation to those of the other fabric edge in such a way that they mesh overlap with each other when the fabric edges are brought together, so that a channel for the passage of a plug wire is created. The plug wire then forms the coupling of the fabric edges on both sides, so that an endless machine covering is created.

Bei den bisher bekannten, flachgewebten Geweben sind die Nahtschlaufen zur Gewebekante hin geschlossen, weil sich die die Nahtschlaufen bildenden Längsfäden im Bereich der Gewebekante nochmals kreuzen. Diese Kreuzung ist die konsequente Fortsetzung des Gewebeschemas bis zur Gewebekante hin.In the previously known, flat-woven fabrics, the seam loops are closed towards the fabric edge because the longitudinal threads forming the seam loops cross again in the area of the fabric edge. This crossing is the logical continuation of the fabric scheme up to the fabric edge.

Bei dieser Ausbildung schließen sich die Nahtschlaufen unter Zugbelastung sehr stark um den Steckdraht, wodurch die Krafteinleitung in den Gewebekörper ungünstig ist Außerdem ist die Einführung des Steckdrahtes bei einer Montage unter Zugbelastung außerordentlich schwierig.With this design, the seam loops close very tightly around the plug wire under tensile load, as a result of which the introduction of force into the fabric body is unfavorable. In addition, the insertion of the plug wire is extremely difficult during assembly under tensile load.

Der Erfindung liegt die Aufgabe zugrunde, die Nahtschlaufen bei einer Maschinenbespannung der eingangs genannten Art so auszubilden, daß die Krafteinleitung in den Gewebekörper günstiger ist und die Montage bei Zugbelastung erleichtert wird.The invention has for its object to form the seam loops in a machine clothing of the type mentioned so that the introduction of force in the fabric body is cheaper and the assembly is easier under tensile loads.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß sämtliche Nahtschlaufen U-förmig und zur Gewebekante hin offen ausgebildet sind.This object is achieved in that all seam loops are U-shaped and open towards the fabric edge.

Erfindungsgemäß werden die Längsfäden, die Nahtschlaufen bilden sollen, im Bereich der Gewebekante so geführt, daß sie sich nicht mehr überkreuzen, sondern im wesentlichen gerade aus dem Gewebe heraus bzw. in dieses hineinlaufen. Hierdurch entsteht eine zur Gewebekante hin offene Nahtschlaufe, die sich auch unter starkem Zug nicht schließen kann. Entsprechend werden die auftretenden Kräfte besser in den Gewebekörper eingeleitet und verteilt. Das Einführen eines Steckdrahtes ist selbst unter Zugbelastung relativ einfach, da die Schlaufe auch bei dieser Belastung offen bleibt.According to the invention, the longitudinal threads that are to form seam loops are guided in the area of the fabric edge in such a way that they no longer cross over but essentially run straight out of the fabric or into it. This creates a seam loop that is open towards the edge of the fabric and that cannot close even under strong tension. Accordingly, the forces that occur are better introduced and distributed into the tissue body. The insertion of a plug wire is relatively easy even under tensile load, since the loop remains open even under this load.

In Ausbildung der Erfindung ist vorgesehen, daß die die Nahtschlaufen bildenden Längsfäden an den Innenseiten von Querfäden aus der Gewebekante aus- und in diese wieder eintreten. Diese an sich bekannte Führung der Längsfäden ist für die erfindungsgemäße Ausbildung der Nahtschlaufen besonders vorteilhaft, weil die jeweils letzte Kreuzung der Längsfäden besonders weit von der Gewebekante wegliegt, so daß sehr offene Nahtschlaufen entstehen. Dabei leisten die an der Gewebekante liegenden Querfäden nur geringen Widerstand, wenn sie unter Zugbelastung der Nahtschlaufen auseinandergedrückt werden.In an embodiment of the invention it is provided that the longitudinal threads forming the seam loops on the inside of transverse threads emerge from the fabric edge and re-enter it. This known guiding of the longitudinal threads is particularly advantageous for the formation of the seam loops according to the invention, because the last crossing of the longitudinal threads lies particularly far away from the fabric edge, so that very open seam loops are created. The transverse threads on the fabric edge offer little resistance if they are pushed apart under tensile stress on the seam loops.

Die erfindungsgemäße Nahtschlaufenform eröffnet zudem die Möglichkeit, zusätzliche Füllfäden darin einzusetzen. Hierdurch kann die Durchlässigkeit im Nahtbereich derjenigen in den übrigen Bereichen der Maschinenbespannung angepaßt werden. Damit diese Füllfäden einen guten Halt haben, sollten sie von einem Teil der die Gewebekanten bildenden Schlaufen eingebunden sein, während der andere Teil die Füllfäden nicht einbindet und sie deshalb in die Nahtschlaufe drückt.The seam loop shape according to the invention also opens up the possibility of using additional filler threads therein. This allows the permeability in the seam area those in the other areas of the machine clothing are adapted. So that these filler threads have a good hold, they should be bound by part of the loops forming the fabric edges, while the other part does not bind the filler threads and therefore presses them into the seam loop.

Die Erfindung sieht schließlich vor, daß die Enden der Längsfäden derart zurückgewebt sind, daß sie die Bindung des benachbarten Längsfadens fortsetzen. Durch diese an sich bekannte Führung der Längsfäden wird eine besonders gute Krafteinleitung der die Nahtschlaufen bildenden Längsfäden in den Gewebekörper erreicht.Finally, the invention provides that the ends of the longitudinal threads are woven back in such a way that they continue the binding of the adjacent longitudinal thread. This known guiding of the longitudinal threads achieves a particularly good introduction of force of the longitudinal threads forming the seam loops into the fabric body.

In der Zeichnung ist die Erfindung an Hand eines Ausführungsbeispiels näher veranschaulicht Sie zeigt einen Längsschnitt durch den Nahtbereich eines doppellagigen Papiermaschinengewebes (1), das insbesondere als Trägergewebe für einen Pressenfilz mit Naht geeignet ist. Für diesen Verwendungszweck wird auf die Oberseite des Papiermaschinengewebes (1) ein Vlies aufgelegt und dieses anschließend mit dem Papiermaschinengewebe (1) vernadelt.The invention is illustrated in more detail in the drawing using an exemplary embodiment. It shows a longitudinal section through the seam region of a double-layer paper machine fabric (1), which is particularly suitable as a carrier fabric for a press felt with a seam. For this purpose, a fleece is placed on the top of the paper machine fabric (1) and this is then needled to the paper machine fabric (1).

Das Papiermaschinengewebe (1) besteht aus zwei Lagen monofilen Querfäden - beispielhaft mit (2) bezeichnet -sowie aus Längsfäden, von denen hier auf jeder Seite nur zwei Längsfäden (3, 4) bzw. (5, 6) eingezeichnet sind Alle Längsfäden (3, 4, 5, 6) binden die Querfäden (2) in Kröpfungen - beispielshaft mit (7) bezeichnet - ein, wobei jeder Längsfaden (3, 4, 5, 6) nach dem Einbinden eines Querfadens (2) in der unteren Lage einen Querfaden (2) in der oberen Lage einbindet. Das Papiermaschinengewebe (1) ist damit als Flachgewebe hergestellt.The paper machine fabric (1) consists of two layers of monofilament transverse threads - denoted by (2) for example - as well as longitudinal threads, of which only two longitudinal threads (3, 4) or (5, 6) are shown on each side. All longitudinal threads (3 , 4, 5, 6) tie the transverse threads (2) into offsets - for example designated by (7) -, each longitudinal thread (3, 4, 5, 6) having a transverse thread (2) in the lower layer after binding Cross thread (2) ties in the top layer. The paper machine fabric (1) is thus a flat fabric produced.

Die Mehrzahl der Längsfäden (4, 6) bilden im Bereich der Gewebekanten (8, 9) enge Schlaufen (10, 11) und werden dann in das Papiermaschinengewebe (1) wieder zurückgewebt. Die zurückgewebten Abschnitte (12, 13) verlaufen dann spiegelbildlich zur Bindung der zugehörigen Längsfäden (4, 6). In den hier nicht mehr dargeste en Bereichen enden die zurückgewebten Abschnitte (12, 13). Dort treffen sie auf das verkürzte Ende eines benachbarten Längsfadens.The majority of the longitudinal threads (4, 6) form narrow loops (10, 11) in the region of the fabric edges (8, 9) and are then woven back into the paper machine fabric (1). The woven-back sections (12, 13) then run in mirror image to bind the associated longitudinal threads (4, 6). The areas (12, 13) which have been woven back end in the regions which are no longer shown here. There they meet the shortened end of an adjacent longitudinal thread.

Ein Teil der Längsfäden (3, 5) bilden über die Gewebekanten (8, 9) vorstehende Nahtschlaufen (14, 15). Sie passieren mit ihrem vorlaufenden Teil und mit ihren zurückgewebten Abschnitten (16, 17) jeweils das letzte Paar Querfäden (2) an den Innenseiten und laufen danach ohne Kreuzung wieder auseinander. In der gezeigten Darstellung sind die Nahtschlaufen (14, 15) beider Gewebekanten (8, 9) in kämmende Überlappung gebracht, so daß ein Kanal (18) parallel zu den Gewebekanten (8, 9) entsteht, durch den ein Steckdraht (19) als Kupplung gesteckt ist. Die Naht ist durch den Steckdraht (19) geschlossen.Part of the longitudinal threads (3, 5) form projecting seam loops (14, 15) over the fabric edges (8, 9). With their leading part and with their woven-back sections (16, 17), they each pass the last pair of transverse threads (2) on the inside and then diverge again without crossing. In the illustration shown, the seam loops (14, 15) of both fabric edges (8, 9) are brought into meshing overlap, so that a channel (18) is formed parallel to the fabric edges (8, 9), through which a plug wire (19) is used Coupling is inserted. The seam is closed by the plug wire (19).

Durch die besondere Führung sind die Nahtschlaufen (14, 15) zu den Gewebekanten (8, 9) hin offen. Bei Zugbeanspruchung werden die beiden Paare von Querfäden (2) an den Gewebekanten (8, 9) auseinandergedrückt, so daß die Schenkel der Nahtschlaufen (14, 15) gerade in das Gewebe ein- bzw aus dem Gewebe herauslaufen. Da die Längsfäden (3, 5) das jeweils nachfolgende Paar Querfäden (2) an der Außenseite einbindet, bleiben die Nahtschlaufen (14, 15) auch unter starker Zugbeanspruchung zu den jeweiligen Gewebekanten (8, 9) hin offen Im übrigen werden die zurückgewebten Abschnitte (16, 17) der die Nahtschlaufen (14, 15) bildenden Längsfäden (3, 5) entsprechend wie die zurückgewebten Abschnitte (12, 13) der Längsfäden (4, 6) geführt.The special loops open the seam loops (14, 15) to the fabric edges (8, 9). In the event of tensile stress, the two pairs of transverse threads (2) on the fabric edges (8, 9) are pressed apart so that the legs of the seam loops (14, 15) run straight into or out of the fabric. Since the longitudinal threads (3, 5) bind the subsequent pair of transverse threads (2) on the outside, the seam loops (14, 15) remain under strong Tensile stress to the respective fabric edges (8, 9) open. Otherwise, the woven back sections (16, 17) of the longitudinal threads (3, 5) forming the seam loops (14, 15) correspond to the woven back sections (12, 13) of the longitudinal threads (4, 6) performed.

In die Nahtschlaufen (14, 15) ist zudem jeweils ein Füllfaden (20, 21) eingesetzt. Die Füllfäden (20, 21) sind von den Schlaufen (10, 11) der Längsfäden (4, 6) eingebunden Weitere, hier nicht dargestellte Längsfäden verlaufen bei der Schlaufenbildung zwischen dem jeweils letzten Paar Querfäden (2) und den Füllfäden (20, 21), wodurch diese in Richtung auf den Steckdraht (19) gedrückt werden Auf diese Weise werden sie in ihrer Lage fixiert. A filler thread (20, 21) is also inserted in each of the seam loops (14, 15). The filler threads (20, 21) are bound in by the loops (10, 11) of the longitudinal threads (4, 6). Further longitudinal threads, not shown here, run between the last pair of transverse threads (2) and the filler threads (20, 21 ), whereby these are pressed in the direction of the plug wire (19). In this way they are fixed in their position.
