Technisches Gebiet Die Erfindung betrifft ein Verfahren zur Herstellung einer Gewebebahn, insbesondere eines Bandgewebes, mit einer Samtkante gemäss Oberbegriff des Anspruches 1 sowie eine Vorrichtung zur Durchführung des Verfahrens gemäss Oberbegriff des Anspruches 8.TECHNICAL FIELD The invention relates to a method for producing a fabric web, in particular a tape fabric, with a velvet edge according to the preamble of claim 1 and a device for carrying out the method according to the preamble of claim 8.
Stand der TechnikState of the art
Ein Verfahren und eine Vorrichtung der eingangs genannten Art sind aus der EP 0 546 485A bekannt. Dort wird beschrieben, dass eine auf einer Webmaschine hergestellte Breitgewebebahn in einzelne Bänder zerschnitten wird, wobei nach dem Schneiden an der Schneidkante angrenzende Kettfäden herausgezogen und ab- geführt werden. Die freiliegenden Enden der Schussfäden bilden dann die Fransen einer Samtkante. Zum Herausziehen der Kettfäden dient eine Abzugsvorrichtung, die über der Gewebebahn angeordnet ist und ein rotierendes Rohr beinhaltet, durch das die abzuziehenden Kettfäden hindurchzuführen sind. Durch Reibkontakt werden die abgezogenen Kettfäden nach Art eines Seiles zusammenge- dreht und einer entsprechenden Abzugsvorrichtung zugeführt. Nachteilig ist es, dass durch den freien Abzug der Kettfäden aus der Gewebebahn kein kontrollierter Abzug gewährleistet ist und insbesondere die Gefahr besteht, dass die in der Gewebebahn vorhandenen Kettfäden, die verbleiben sollen, gelockert werden. Damit ergibt sich keine einwandfreie, gleichmässige und dauerhafte Samtkante an der Gewebebahn. Überdies sind sowohl das Verfahren wie die Vorrichtung relativ kompliziert.A method and a device of the aforementioned type are known from EP 0 546 485A. There, it is described that a wide fabric web produced on a loom is cut into individual ribbons, with warp threads adjacent to the cutting edge being pulled out and removed after cutting. The exposed ends of the weft threads then form the fringes of a velvet edge. To pull out the warp threads is a take-off device, which is arranged above the fabric web and includes a rotating tube through which the warp threads to be deducted are to pass. By frictional contact the withdrawn warp threads are twisted together in the manner of a rope and fed to a corresponding take-off device. It is disadvantageous that a controlled withdrawal is not guaranteed by the free withdrawal of the warp threads from the fabric web and in particular there is the risk that the warp threads present in the fabric web, which are to remain, are loosened. This results in no perfect, uniform and durable velvet edge on the fabric web. Moreover, both the method and the device are relatively complicated.
Darstellung der ErfindungPresentation of the invention
Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung einer Gewebebahn, insbesondere eines Bandgewebes, mit einer Samtkante und eine Vorrichtung zur Durchführung des Verfahrens zu verbessern. Diese Aufgabe wird erfindungsgemäss gelöst:The object of the invention is to improve a method for producing a fabric web, in particular a tape fabric, with a velvet edge and a device for carrying out the method. This object is achieved according to the invention:
a) beim Verfahren der eingangs genannten Art durch die kennzeichnenden Merkmale des Anspruches 1; b) bei der Vorrichtung der eingangs genannten Art durch die kennzeichnenden Merkmale des Anspruches 8.a) in the method of the type mentioned by the characterizing features of claim 1; b) in the device of the type mentioned by the characterizing features of claim 8
Dadurch, dass man nach dem Schneidwerkzeug an mindestens einer Seite in der Gewebebahn und im Abstand der abzuziehenden Kettfäden von der Schneidkante ein Ablenkglied anordnet, um die abzuziehenden Kettfäden von den verbleibenden Kettfäden zu trennen, ergibt sich eine genau definiertes Abziehen der Kettfäden aus dem Randbereich der Gewebebahn. Dabei werden insbesondere die in der Gewebebahn verbleibenden Kettfäden in ihrer Lage gehalten und es wird verhindert, dass sie sich im Zuge des Abziehens der Kettfäden lockern können. Das Ablenkglied sorgt vielmehr noch dafür, dass die verbleibenden Kettfäden der Gewebebahn fester aneinander gedrückt werden. Damit ergibt sich eine Samtkante mit Fransen von gleich bleibender Länge und mit grosser Dauerhaftigkeit.Characterized in that after the cutting tool on at least one side in the fabric web and at a distance of the deducting warp threads of the cutting edge a deflecting member to separate the deducting warp threads from the remaining warp threads, there is a well-defined stripping the warp threads from the edge region of fabric web. In particular, the remaining in the fabric web warp threads are held in position and it is prevented that they can loosen in the course of stripping the warp threads. Rather, the deflector still ensures that the remaining warp threads of the fabric web are pressed together more firmly. This results in a velvet edge with fringes of consistent length and with great durability.
Die Vorrichtung zur Durchführung des Verfahrens ist ausserordentlich einfach und wirksam, da sie lediglich die Anordnung eines Ablenkgliedes erfordert, dass dem Schneidwerkzeug nachgeschaltet stationär an der Vorrichtung angeordnet ist.The device for carrying out the method is extremely simple and effective, since it only requires the arrangement of a deflection member that is arranged downstream of the cutting tool on the device.
Vorteilhafte Ausgestaltungen des Verfahrens sind in den Ansprüchen 2 bis 8, und hinsichtlich der Vorrichtung in den Ansprüchen 10 bis 14 beschrieben.Advantageous embodiments of the method are described in claims 2 to 8, and in terms of the device in claims 10 to 14.
Grundsätzlich ist es möglich, eine Gewebebahn herzustellen, die nur auf einer Seite eine Samtkante aufweist. Der von der Gewebebahn abgeschnittene Teil kann dann beispielsweise ein Abfall sein, der zu entsorgen ist. Vorteilhafter ist das Verfahren nach Anspruch 2, wonach beidseits des Schneidwerkzeuges ein solches Ablenkglied angeordnet ist, um in beiden getrennten Gewebebahnen Kettfäden zur Bildung von Samtkanten abzuziehen. Damit ist die Samtkantenbildung symmetrisch und verbessert die gleichmässige Bildung der Samtkanten. Ausserdem ermöglicht es diese Ausbildung, eine breite Gewebebahn in einzelne Bandgewebe zu unterteilen, die beidseits mit einer Samtkante versehen sind, so wie dies aus der EP 0 546 485 bekannt ist.In principle, it is possible to produce a fabric web which has a velvet edge on only one side. The cut off of the fabric web part may then be, for example, a waste to be disposed of. More advantageously, the method of claim 2, wherein on both sides of the cutting tool such a deflecting member is arranged to deduct warp threads in both separate fabric webs to form velvet edges. Thus, the velvet edge formation is symmetrical and improves the uniform formation of the velvet edges. In addition, this design makes it possible to divide a wide fabric web into individual band webs which are provided on both sides with a velvet edge, as is known from EP 0 546 485.
Die Samtkante lässt sich weiter verbessern, wenn man gemäss Anspruch 3 in der Gewebebahn den Samtkantenbereich zur Gewebebahn hin begrenzende Schmelzfäden anordnet, deren Schmelztemperatur kleiner ist als eine etwaige Schmelztemperatur der übrigen Fäden der Gewebebahn. Zum Schmelzen kann dann gemäss Anspruch 4 entweder das Schneidwerkzeug verwendet werden, das auf die Temperatur der Schmelzkettfäden aufgeheizt ist, oder gemäss Anspruch 5 das Ablenkglied, das auf eine entsprechende Temperatur aufgeheizt ist. Unter Umständen ist es auch denkbar, gemäss Anspruch 6 in der Gewebebahn Klebfäden anzuordnen, die den Samtkantenbereich zur Gewebebahn hin begrenzen. Dabei ist es von Vorteil, wenn man nach Anspruch 7 die Ablenkglieder so anord- net, dass zwischen dem Ablenkglied und dem Schmelzkettfaden einerseits oder einem Klebekettfaden andererseits mindestens ein normaler Kettfaden angeordnet ist. Dadurch lässt sich die Samtkante weiter verfestigen, ohne dass das Ablenkglied und/oder die Fransen der Samtkante verschmutzt werden oder gar miteinander verkleben.The velvet edge can be further improved if, according to claim 3, in the fabric web, the seam edge region to the fabric web is arranged to be delimited by melting threads whose melting temperature is less than a possible melting temperature of the remaining threads of the fabric web. For melting then either the cutting tool can be used according to claim 4, which is heated to the temperature of the melt warp threads, or according to claim 5, the deflection member which is heated to a corresponding temperature. Under certain circumstances, it is also conceivable to arrange adhesive threads in the fabric web according to claim 6, which limit the velvet edge region to the fabric web. It is advantageous if, according to claim 7, the deflection members are arranged in such a way that at least one normal warp thread is arranged between the deflection member and the fusion warp thread on the one hand or a glue warp thread on the other hand. As a result, the velvet edge can be further solidified without the deflecting member and / or the fringes of the velvet edge becoming dirty or even sticking together.
Grundsätzlich kann das Schneiden der Schussfäden thermisch mittels Durchschmelzen oder Durchbrennen erfolgen. Dies liefert in der Regel jedoch keine einwandfreien Enden der Fransen. Gemäss Anspruch 8 erfolgt das Schneiden vorzugsweise mechanisch, beispielsweise mittels eines Schneidmessers oder ei- ner Schere, um einwandfreie Enden der Fransen zu erhalten.In principle, the cutting of the weft threads can take place thermally by means of melting through or burning through. However, this usually does not provide perfect ends of the fringes. According to claim 8, the cutting preferably takes place mechanically, for example by means of a cutting knife or scissors, in order to obtain perfect ends of the fringes.
Die Ansprüche 9 bis 13 beschreiben verschiedene Vorrichtungsmerkmale, um die oben diskutierten Verfahrensvarianten zu verwirklichen.Claims 9 to 13 describe various apparatus features to realize the method variants discussed above.
Grundsätzlich kann die Vorrichtung zur Durchführung des Verfahrens unabhängig von einer Webmaschine sein, wobei die Gewebebahnliefervorrichtung aus einer Rolle bestehen kann, zu der die Gewebebahn aufgewickelt ist. Vorteilhaft ist es jedoch, wenn die Vorrichtung gemäss Anspruch 14 in eine Webmaschine integriert ist, wobei sie der Webstelle nachgeordnet ist.In principle, the device for carrying out the method can be independent of a weaving machine, wherein the fabric web feeding device can consist of a roll, to which the fabric web is wound up. It is advantageous However, if the device is integrated according to claim 14 in a weaving machine, wherein it is arranged downstream of the weaving.
Kurze Beschreibung der Zeichnungen Ausführungsbeispiele der Erfindung werden nachfolgend anhand schematischer Zeichnungen näher beschrieben, dabei zeigen:BRIEF DESCRIPTION OF THE DRAWINGS Exemplary embodiments of the invention will be described in more detail below with reference to schematic drawings, in which:

Weαe zur Ausführung der ErfindungWeαe for carrying out the invention
Die Figur 1 zeigt eine Vorrichtung 2 zur Herstellung einer Gewebebahn 4 mit ei- ner Samtkante 6. Sie enthält eine Gewebebahnliefervorrichtung 8, welche im vorliegenden Beispiel als bekannte Webmaschine ausgebildet ist. An einer Webstelle 10 wird eine Gewebebahn 4 erzeugt, die an einem Warenabzug 14 abgezogen wird.1 shows a device 2 for producing a fabric web 4 with a velvet edge 6. It contains a fabric web delivery device 8, which is formed in the present example as a known weaving machine. At a weaving location 10, a fabric web 4 is produced, which is pulled off at a fabric take-off 14.
Wie insbesondere aus Figur 2 weiter zu entnehmen ist, ist der Webstelle 10 ein Schneidwerkzeug 16 nachgeordnet, das beispielsweise als stehendes oder rotierendes Schneidmesser oder gegebenenfalls als Schere ausgebildet sein kann. Das Schneidwerkzeug 16 durchtrennt Schussfäden 18 in Richtung der Kettfäden 20, sodass die Gewebebahn 4 in zwei Gewebebahnen 4a, 4b unterteilt wird. Beidseits des Schneidwerkzeuges 16 sind Ablenkglieder 22, 24 angeordnet, und zwar in einem solchen seitlichen Abstand zum Schneidwerkzeug 16, der den Kettfäden 20a entspricht, die aus der Gewebebahn entfernt werden sollen, um die Samtkante 6 zu bilden. Die Ablenkglieder 22, 24 sorgen für ein geordnetes Abziehen der Kettfäden 20a, sodass eine gleichmässige Samtkante 6 gebildet wird, ohne die verbleibenden Kettfäden 20 zu lockern. Die Ablenkglieder 22, 24 bewirken sogar ein Eindrücken und damit Verdichten der verbleibenden Kettfäden gegen die Gewebebahn und damit eine Verfestigung der Samtkante 6 und erhöhen somit die Dauerhaftigkeit der Samtkante 6. Die zu entfernenden Kettfäden 20a werden beidseits mittels Abzugsvorrichtungen 26, 28 abgeführt.As can also be seen in particular from FIG. 2, the weaving site 10 is followed by a cutting tool 16, which may be designed, for example, as a stationary or rotating cutting blade or possibly as a pair of scissors. The cutting tool 16 cuts through weft threads 18 in the direction of the warp threads 20 so that the fabric web 4 is divided into two fabric webs 4a, 4b. On both sides of the cutting tool 16 deflecting members 22, 24 are arranged, in such a lateral distance to the cutting tool 16, which corresponds to the warp threads 20 a, which are to be removed from the fabric web to form the velvet edge 6. The deflecting members 22, 24 provide for an orderly stripping of the warp threads 20a, so that a uniform velvet edge 6 is formed without loosening the remaining warp threads 20. The deflection members 22, 24 even cause a depression and thus compression of the remaining warp threads against the fabric web and thus a solidification of the velvet edge 6 and thus increase the durability of the velvet edge 6. The warp threads 20a to be removed are removed on both sides by means of draw-off devices 26, 28.
Zur weiteren Verbesserung der Verfestigung der Samtkanten 6 enthält die Ge- webebahn 4 Schmelzkettfäden 20b, deren Schmelztemperatur kleiner ist als die Schmelztemperatur der übrigen Fäden der Gewebebahn. Die Schmelzkettfäden 20b werden vorzugsweise mittels der Ablenkglieder 22,24 aktiviert, die auf eine Temperatur aufheizbar sind, welche der Schmelztemperatur der Schmelzkettfäden 20b entspricht. Um ein Verkleben der durch die freien Enden der Schussfä- den 18 gebildeten Fransen 30 der Samtkante 6 untereinander beziehungsweise mit den Ablenkgliedern 22, 24 zu verhindern, ist zwischen den Ablenkgliedern 22, 24 und den Schmelzkettfäden 20b mindestens ein normaler Kettfaden 20 angeordnet. Dies ergibt eine gleichmässige Samtkante 6, bei der die Fransen 30 überall eine gleiche Länge aufweisen, und die sich durch besonders gute Stabili- tat und Dauerfestigkeit auszeichnet.To further improve the solidification of the velvet edges 6, the fabric web 4 contains melt warp threads 20b whose melting temperature is less than the melting temperature of the remaining threads of the fabric web. The melt warp yarns 20b are preferably activated by means of the deflector members 22,24 which are heatable to a temperature which corresponds to the melting temperature of the melt warp yarns 20b. In order to prevent sticking of the fringes 30 of the velvet edge 6 formed by the free ends of the weft threads 18 with one another or with the deflecting members 22, 24, at least one normal warp thread 20 is arranged between the deflecting members 22, 24 and the melt warp threads 20b. This results in a uniform velvet edge 6, in which the fringes 30 have the same length everywhere, and which is characterized by particularly good stability and fatigue strength.
Anstelle der Schmelzkettfäden 20b ist es auch denkbar, Klebekettfäden zu verwenden.Instead of the melt warp threads 20b, it is also conceivable to use adhesive warp threads.
Die Vorrichtung zeichnet sich durch einen besonders einfachen Aufbau aus, da die Ablenkglieder 22, 24 stationär angeordnet sind also keines Antriebes bedürfen. Die Vorrichtung kann auch so ausgebildet sein, dass aus einer breiten Gewebebahn mehrere Bandgewebe mit beidseitigen Samtkanten hergestellt werden, wie dies aus der EP 0 546 485 bekannt ist. The device is characterized by a particularly simple structure, since the deflection members 22, 24 are arranged stationary so do not require a drive. The device can also be designed in such a way that a plurality of tape webs having velvet edges on both sides are produced from a wide web of fabric, as is known from EP 0 546 485.
