Description

Die Erfindung betrifft eine Webmaschine mit Gewebestütze gemäss dem Oberbegriff von Anspruch 1.The invention relates to a weaving machine with a fabric support according to the preamble of claim 1.

Bei Webmaschinen wird normalerweise nahe der Anschlaglinie des Schussfadens an den Geweberand eine Gewebestütze montiert, damit das Gewebe bezüglich des Webblattes und somit auch die Kettfäden bezüglich des Schusseintragsorgans der Webmaschine eine einigermassen definierte Lage einnehmen. Bei Webmaschinen mit pneumatischem Eintrag des Schussfadens hat sich eine Bauform des Webblattes durchgesetzt, wie sie eingangs umrissen wurde. Der Abstand der Kanalwände und die Tiefe des Kanals haben Werte in der Grössenordnung von 10 mm, und die Gewebestütze ist normalerweise aus Platzgründen neben dem erwähnten Führungskanal in der Anschlagstellung der Weblade angeordnet. Es hat sich bei Versuchen an einer Luftdüsenwebmaschine gezeigt, dass besonders bei der Herstellung sehr dichter Gewebe die relativ grosse Distanz zwischen der Gewebestütze und der Anschlaglinie des Webblattes in dessen Kanalgrund als nachteilig auswirkt, da der Geweberand beim Aufschlagen des Webblattes sich entlang des Kanalgrundes verschieben kann, wenn der Kanalgrund nicht genau senkrecht zum Gewebe steht und die resultierende Zugkraft der Kettfäden ebenfalls schräg zum Kanalgrund wirkt.In the case of weaving machines, a fabric support is normally mounted near the stop line of the weft thread on the fabric edge, so that the fabric is in a somewhat defined position with respect to the reed, and thus also the warp threads with respect to the weft insertion member of the loom. In the case of weaving machines with pneumatic insertion of the weft thread, a design of the reed has become established, as was outlined at the beginning. The distance between the channel walls and the depth of the channel have values of the order of 10 mm, and the fabric support is normally arranged next to the guide channel mentioned in the stop position of the sley for space reasons. Tests on an air jet loom have shown that Especially in the production of very dense fabric, the relatively large distance between the fabric support and the stop line of the reed in the channel base has a disadvantage, since the edge of the fabric can move along the channel base when the reed is opened if the channel base is not exactly perpendicular to the fabric and the resulting tensile force of the warp threads also acts obliquely to the channel base.

Aus der EP-A-0 336 408 (Dokument gemäss Art. 54(3)) ist ein Breithaltertisch mit einem Vorsprung bekannt, wobei die vorderste Kante des Vorsprungs während des Anschlagens etwa in der Mitte des Schusseintragskanals, und zwar sowohl in horizontaler als auch in vertikaler Richtung, zu liegen kommt. Dadurch wird unabhängig von der Art des Gewebes die Anschlaglinie respektive der Anschlagpunkt immer relativ in der Mitte des Schusseintragskanals gebildet. Somit lässt sich vermeiden, dass die Anschlaglinie des Gewebes im Schusseintragskanal derart weit nach oben oder unter wandert, dass das Gewebe mit der Kante des Webblattzahnes kollidiert, was den Schussfaden beschädigen würde.A spreader table with a projection is known from EP-A-0 336 408 (document according to Art. 54 (3)), the foremost edge of the projection during the striking approximately in the middle of the weft insertion channel, both horizontally and in the vertical direction. As a result, regardless of the type of fabric, the stop line or the stop point is always formed relatively in the middle of the weft insertion channel. It can thus be avoided that the stop line of the fabric in the weft insertion channel moves so far up or down that the fabric collides with the edge of the reed tooth, which would damage the weft thread.

Die Anschlaglinie des Gewebes kann sich jedoch innerhalb des Schusseintragskanals verschieben, was zur Folge hat, dass die Schussfäden nicht gleichmässig in das Gewebe eingewoben werden und so die Schussdichte nicht gleichmässig ist.However, the stop line of the fabric can shift within the weft insertion channel, with the result that the weft threads are not woven evenly into the fabric and the weft density is therefore not uniform.

Es ist Aufgabe der vorliegenden Erfindung, die Gewebestütze einer Webmaschine mit einem aus profilierten Lamellen gebildeten Webblatt so zu verbessern und so anzuordnen, dass das Gewebe insbesondere während des Schussanschlages besser geführt wird.It is an object of the present invention to improve the fabric support of a weaving machine with a reed formed from profiled lamellae and to arrange it in such a way that the fabric is guided better, especially during the weft attack.

Die Erfindung löst die Aufgabe gemäss den kennzeichnenden Merkmalen von Anspruch 1.The invention achieves the object according to the characterizing features of claim 1.

Die Gewebestütze besitzt in einer vorteilhaften Ausführungsform an ihrem dem Gewebe zugewandten Ende einen in den Führungskanal während des Blattanschlages ragenden schnabelförmigen Vorsprung. Als geringsten Abstand zwischen der Gewebeführungsfläche und dem Kanalgrund wird man grössenordnungsmässig 1 mm wählen, damit es bei Deformationen zwischen der Weblade und der Gewebestütze unter keinen Umständen zu einer Berührung zwischen diesen Teilen kommt. Die Gewebefuhrungsfläche wird gegenüber dem Führungskanal am besten so eingestellt, dass der Abstand zwischen ihr und der oberen Kanalwand grössenordnungsmässig 1 mm beträgt. Da das Gewebe auf der Gewebeführungsfläche um einen geringen Winkel umgelenkt wird, führt man sie mit Vorteil ballig aus.In an advantageous embodiment, the tissue support has, at its end facing the tissue, a beak-shaped projection which projects into the guide channel during the blade stop. The smallest distance between the fabric guiding surface and the channel base will be chosen in the order of magnitude of 1 mm, so that there is no contact between these parts in the event of deformation between the sley and the fabric support. The tissue guiding surface is best adjusted relative to the guide channel so that the distance between it and the upper channel wall is of the order of 1 mm. Since the tissue is deflected by a small angle on the tissue guiding surface, it is advantageously performed spherically.

Ein Vorteil der Erfindung ist darin zu sehen, dass die Anschlaglinie des Gewebes in einem eng festgelegten Bereich zu liegen kommt und somit Relativbewegungen des Geweberandes entlang des Webblattes während des Anschlagens des Schussfadens weitgehend ausgeschlossen werden. Dadurch werden die Schussfäden gleichmässiger eingewoben und ein regelmässiges Gewebebild entsteht.An advantage of the invention can be seen in the fact that the stop line of the fabric comes to lie in a narrowly defined area and thus relative movements of the fabric edge along the reed are largely excluded when the weft thread is attached. As a result, the weft threads are woven in more evenly and a regular fabric image is created.

Im folgenden wird die Erfindung anhand der Figuren im einzelnen beschrieben.The invention is described in detail below with reference to the figures.

In Fig. 1 sind Teile der Weblade 3, die Gewebestütze 40 mit einem mit ihr verschraubten Halter 41 sowie das Gewebe 1 links vom Webblatt 31 und die Kettfäden 2a und 2b rechts vom Webblatt 31 gezeigt, wobei zwischen den schräg nach oben bzw. schräg nach unten gespannten Kettfäden 2a und 2b das Webfach 2 gebildet wird. Der Anschlagpunkt des Webblattes auf dem Gewebe 1 im Kanalgrund 33 wird mit P bezeichnete. Das Webblatt 31 ist mittels eines Klemmstückes 35 im Ladenprofil 34 verschraubt. Ebenfalls mit dem Ladenprofil 34 ist ein Hilfsdüsenblock 36 verschraubt, aus welchem eine Hilfsdüse 36a ragt. Da sie beim Gewebeanschlag innerhalb der Gewebestütze 40 liegt, sind in die Gewebestütze 40 Schlitze 44 eingefräst. In Fig. 1 ist die Weblade 3 in der Stellung gezeichnet, in welcher der Kanalgrund 33 in den nicht gezeichneten Schussfaden bis an die Anschlaglinie P des Gewebes 1 befördert hat. In diesem Augenblick beginnt in einer Schwenkung der Weblade nach links der Gewebeanschlag. Das Ende des Gewebeanschlages ist in Fig. 2 gezeigt, wobei das dem Führungskanal 32 zugewandte Ende der Führungsfläche 42 knapp vor dem Führungskanal 32 steht. Die Anschlaglinie P ist gegenüber Fig. 1 entlang des Kanalgrundes 33 etwas nach unten gewandert. Da die Stellung der Anschlaglinie P am Kanalgrund von Anschlag zu Anschlag leicht variieren kann, ergeben sich unterschiedliche Verhältnisse für die jeweils anzuschlagenden Schussfäden. Dies kann zu einem ungleichmässigen Einweben der Schussfäden und schlechtem Gewebeausfall besonders bei dichten Geweben führen.In Fig. 1 parts of the sley 3, the fabric support 40 with a screwed with it holder 41 and the fabric 1 to the left of the reed 31 and the warp threads 2a and 2b to the right of the reed 31 are shown, with the diagonally upwards or obliquely downwards warp threads 2a and 2b stretched below the shed 2 is formed. The anchor point of the Weave on the fabric 1 in the channel base 33 is designated with P. The reed 31 is screwed into the shop profile 34 by means of a clamping piece 35. An auxiliary nozzle block 36 is also screwed to the shutter profile 34, from which an auxiliary nozzle 36a protrudes. Since it lies within the tissue support 40 at the tissue stop, slots 44 are milled into the tissue support 40. In Fig. 1, the sley 3 is drawn in the position in which the channel base 33 has conveyed into the weft thread, not shown, up to the stop line P of the fabric 1. At this moment the fabric stop begins in a swivel of the sley to the left. The end of the tissue stop is shown in FIG. 2, the end of the guide surface 42 facing the guide channel 32 being just in front of the guide channel 32. The stop line P has migrated somewhat downward along the channel base 33 in relation to FIG. 1. Since the position of the stop line P on the channel base can vary slightly from stop to stop, there are different conditions for the weft threads to be struck in each case. This can lead to an uneven weaving of the weft threads and bad tissue loss, especially with dense fabrics.

Gemäss der Erfindung besitzt die Gewebestütze in Fig. 3 einen schnabelförmigen Vorsprung 45, wodurch sich eine wesentlich vergrösserte Führungsfläche 43 ergibt, die bis nahe an den Kanalgrund 33 reicht und in nur geringem Abstand von der oberen Kanalwand 37 liegt. Die Anschlaglinie P des Gewebes liegt hier aufgrund der relativen Lagen der Führungsfläche 43, der oberen Führungswand 37 und des Kanalgrundes 33 zueinander gerade am Ende des bogenförmigen Ueberganges zwischen der oberen Kanalwand 37 und dem Kanalgrund 33. Die Gewebestütze verhindert ein Rutschen der Anschlaglinie P weiter nach unten entlang des Kanalgrundes 33, der bogenförmige Uebergang 39 zwischen der oberen Kanalwand 37 und dem Kanalgrund 33 ein Gleiten des Gewebes bzw. der Anschlaglinie P in diesen Uebergangsbereich. Das Gewebe ist somit am Ende der Anschlagbewegung der Weblade in einer genau definierten Stellung.According to the invention, the fabric support in FIG. 3 has a beak-shaped projection 45, which results in a substantially enlarged guide surface 43 which extends close to the channel base 33 and is only a short distance from the upper channel wall 37. The stop line P of the fabric lies here due to the relative positions of the guide surface 43, the upper guide wall 37 and the channel base 33 to each other just at the end of the arcuate transition between the upper channel wall 37 and the channel base 33. The fabric support prevents the stop line P from slipping further below along the channel bottom 33, the arched transition 39 between the upper Channel wall 37 and the channel base 33 a sliding of the tissue or the stop line P in this transition area. The fabric is thus in a precisely defined position at the end of the stop movement of the sley.

Anhand der Fig. 4a und 4b wird noch erläutert, warum gerade bei dichten Geweben reproduzierbare Verhältnisse von einem Anschlag zum nächsten vorliegen müssen. Wie aus Fig. 4a, einer vergrösserten Darstellung eines Ausschnittes des Gewebes und der Kettfäden 1 bzw. 2a und 2b gemäss Fig. 3, hervorgeht, liegen die weiss gezeichneten Schussfäden A,B,C,D,...I jeweils um ein geringes Mass nach oben bzw. nach unten versetzt nebeneinander. Sie werden von den schwarz gezeichneten Kettfäden 2a, 2b umschlungen, wobei üblicherweise nicht jeder Kettfäden bei den gebräuchlichen Gewebebindungen abwechselnd oberhalb und unterhalb eines und des benachbarten Schussfadens A,B zu liegen kommt. Der Schussfaden I wird während des Anschlages aus einer Lage zwischen den Kettfäden 2a, 2b innerhalb des Webfaches 2 bis an die Anschlaglinie P mittels des Webblattes 31 befördert, wobei er etwas oberhalb des vorher angeschlagenen Schussfadens H zu liegen kommt, da die unteren Kettfäden 2b wesentlich stärker als die oberen Kettfäden 2a gespannt sind. Durch das starke Einweben der Kettfäden wird der Schussfaden I später ebenso wie die Schussfäden A,C,E,G eine gegenüber den anderen Schussfäden B,D,F,H erhöhte Lage einnehmen, so dass er seine gegenüber dem Schussfaden H erhöhte Lage nicht mehr wesentlich zu ändern braucht. Anders sieht es beim nächsten eingetragenen und anzuschlagenden Schussfaden K aus. Er wird später in der Ebene der unteren Schussfäden B,D,F,H liegen, wird aber aufgrund der erwähnten Spannungsverhältnisse der Kettfäden 2a, 2b zunächst gegenüber dem Schussfaden I in einer etwas erhöhten Lage angeschlagen. Die Schussfäden erreichen demnach erst im Laufe mehrerer nachfolgender Anschläge ihre endgültige Position relativ zu den jeweils benachbarten Schussfäden. Durch die Verlängerung der Gewebeführungsfläche 43 mittels des Vorsprunges 45 Richtung Anschlaglinie P gemäss der Erfindung wird erreicht, dass bei jedem Schussanschlag reproduzierbare Verhältnisse vorliegen, da keine Vertikalbewegung der Anschlaglinie P auf diese Weise möglich ist, wodurch der Einwebvorgang sehr gleichmässig wird.4a and 4b it will be explained why reproducible conditions from one stop to the next must be present, especially in dense fabrics. As can be seen from FIG. 4a, an enlarged representation of a detail of the fabric and the warp threads 1 or 2a and 2b according to FIG. 3, the weft threads A, B, C, D,... I drawn in white are each slightly smaller Measure up or down next to each other. They are wrapped in the black warp threads 2a, 2b, usually not every warp thread comes to lie alternately above and below one and the adjacent weft thread A, B in the usual weaves. The weft thread I is conveyed from the position between the warp threads 2a, 2b within the shed 2 to the stop line P by means of the reed 31, during which it comes to lie somewhat above the previously weft thread H, since the lower warp threads 2b are essential are tensioned more than the upper warp threads 2a. Due to the strong weaving-in of the warp threads, the weft thread I later, like the weft threads A, C, E, G, will assume a higher position than the other weft threads B, D, F, H, so that it no longer has its higher position than the weft thread H. needs to change significantly. The situation is different for the next weft thread K to be entered and attached. It will later lie in the plane of the lower weft threads B, D, F, H, but due to the tension conditions of the warp threads 2a, 2b mentioned above, it is first cast in a slightly higher position than the weft thread I. The weft threads therefore only reach their final position in the course of several subsequent attacks Position relative to the adjacent weft threads. The extension of the tissue guide surface 43 by means of the projection 45 in the direction of the stop line P according to the invention ensures that reproducible conditions are present with each weft stop, since no vertical movement of the stop line P is possible in this way, as a result of which the weaving process becomes very even.
