Abstract

A weaving machine comprises a guide device (12b) for a cloth run (10), a cutting device (18) arranged between the guide device (12b) and a breast beam (40), followed by a fixation device (18). All aggregates are independently mounted on the weaving machine. Independent mounting greatly facilitates access to the individual aggregates for adjustment and repair purposes and the cutting heads (20) of the cutting device (18) can be adjusted in the warp direction. Cutting can thereby be synchronized with a pattern repeat. The cloth run is nevertheless carefully guided to ensure accurate cutting according to pattern.

Description

Die Erfindung betrifft eine Webmaschine gemäss Oberbegriff des Anspruches 1.The invention relates to a weaving machine according to the preamble of claim 1.

Es ist schon lange bekannt (DE-OS 1 535 330, US-PS 3 486 957, Textil-Praxis 1956, September, S. 951) Bänder, insbesondere Etikettenbänder, nicht auf herkömmlichen Bandwebmaschinen sondern auf relativ breite Gewebe herstellenden Webmaschinen zu erzeugen, weil hierdurch die Produktionskosten so weit gesenkt werden könne, dass man mit den für billige Textilien verwandten gedruckten Etiketten in Wettbewerb treten kann.It has been known for a long time (DE-OS 1 535 330, US Pat. No. 3,486,957, Textil-Praxis 1956, September, p. 951) to produce tapes, in particular label tapes, not on conventional tape looms but on relatively wide fabric-producing looms. because this can reduce production costs to such an extent that one can compete with the printed labels used for cheap textiles.

Theoretisch bereitet die Herstellung von Gewebebändern durch kettfadenparalleles Zerschneiden einer entsprechenden breiten Gewebebahn keine Schwierigkeiten. In der Praxis liess sich jedoch wegen des durch unterschiedliche Kettfadenspannungen hervorgerufenen Krumpfens der Bänder sowie wegen der verkrusteten Bandtrennkanten keine Qualitätsware in einem Arbeitsgang wirtschaftlich erreichen.Theoretically, the production of fabric tapes by cutting a corresponding wide fabric web parallel to the warp thread presents no difficulties. In practice, however, because of the shrinkage of the belts caused by different warp thread tensions and because of the encrusted belt separating edges, no quality goods could be economically achieved in one operation.

Im Bestreben, diese Nachteile zu beheben, ist in der DE-PS 2 302 949 bzw. der US-PS 3 961 650 eine Anordnung beschrieben, die die Lösung darin sieht, dass alle bereits bekannten Vorrichtungen, d.h. ein Breithalter, eine Schneidevorrichtung und eine thermische Fixiervorrichtung komprimiert in einen massiven, über die ganze Gewebebreite sich erstreckenden, speziell ausgebildeten kompakten Trägerbalken integriert werden. Damit wird wohl eine sehr gedrängte Bauart erreicht, doch beseitigt sie die oben erwähnten Nachteile nicht, da die einzelnen Vorrichtungen starr angeordnet und deren Positionen gegeneinander nicht einstellbar sind. Die gedrängte Bauweise erschwert in hohem Masse die Zugänglichkeit und Bedienung und ist zudem schmutzanfällig durch den in einer engen, fast geschlossenen Nut eingesetzten Rundstab eines Klemmbreithalters, da die Gewebebahn durch diese Nut gezogen und an den Ein- und Austrittsschlitzen geklemmt wird und somit Flusen abstreift und lose Fäden aufwickelt. Ein weiterer wesentlicher Nachteil ist, dass das nachteilige Krumpfverhalten und die verkrusteten Bandtrennnkanten nicht mit einem einseitig über bzw.unter den Bändern angeordneten Heizdraht beseitigt werden können. Die gedrängte Bauart lässt aus Platzgründen keine andere Lösung zu, was bedeutet, das die erwähnten Nachteile auch mit dieser Lösung noch nicht beseitigt sind und die vom Markt verlangte Bandqualität noch nicht erreicht werden kann.In an effort to remedy these disadvantages, an arrangement is described in DE-PS 2 302 949 and US-PS 3 961 650, which sees the solution in that all known devices, ie a spreader, a cutting device and one Thermal fixation device can be compressed and integrated into a solid, specially designed, compact support beam that extends over the entire width of the fabric. A very compact design is probably achieved with this, but it does not eliminate the disadvantages mentioned above, since the individual devices rigidly arranged and their positions are not adjustable against each other. The compact design makes access and operation more difficult and is also susceptible to dirt due to the round bar of a clamp spreader inserted in a narrow, almost closed groove, since the fabric web is pulled through this groove and clamped at the inlet and outlet slots and thus wipes off fluff and loose threads wound up. Another major disadvantage is that the disadvantageous shrinkage behavior and the encrusted strip separating edges cannot be eliminated with a heating wire arranged on one side above or below the strips. The compact design does not allow any other solution for reasons of space, which means that the disadvantages mentioned have not yet been remedied with this solution and the strip quality required by the market cannot yet be achieved.

Weiter ist aus der US-PS 4 124 420 eine Vorrichtung bekannt, die ein Breitgewebe zu Bändern zerschneidet. Allerdings ist die Vorrichtung ein selbständiges Aggregat, welches einem Brustbaum einer Webmaschine nachgestaltet ist und aus einer Vielzahl von Umlenkwalzen und einer Tänzervorrichtung zur Einhaltung einer konstanten Bandspannung und Bandgeschwindigkeit an der Schneidvorrichtung besteht. Diese Vorrichtung enthält den Nachteil, dass durch den langen Weg der Gewebebahn die Führung beeinträchtigt ist, sodass ein exaktes mustergenaues Trennen der Gewebebahn in einzelne Bänder nicht gewährleistet ist.Furthermore, a device is known from US Pat. No. 4,124,420 which cuts a wide fabric into ribbons. However, the device is an independent unit, which is modeled on a breast tree of a weaving machine and consists of a plurality of deflecting rollers and a dancer device for maintaining a constant belt tension and belt speed on the cutting device. This device has the disadvantage that the guidance is impaired by the long path of the fabric web, so that an exact pattern-accurate separation of the fabric web into individual bands is not guaranteed.

Aufgabe der Erfindung ist es, eine Webmaschine der eingangs genannten Art zu verbessern.The object of the invention is to improve a loom of the type mentioned.

Die gestellte Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Durch, dass die Führungsvorrichtung und die Schneidvorrichtung voneinander getrennt an der Webmaschine angeordnet sind, d.h. sich also nicht an einem gemeinsamen Träger befinden, ist ihre Zugänglichkeit wesentlich verbessert, sodass sie im Falle von Störungen und Einstellarbeiten leichter zugänglich sind. Hinzu kommt, dass diese einzelnen Vorrichtungen durch ihre voneinander losgelöste Anordnung, beispielsweise am Maschinengestell, individuell optimal ausgestaltet werden können. Dennoch wird durch die nahe Anordnung der Schneidvorrichtung an der Führungsvorrichtung und damit an der Schussfadenanschlagkante eine optimale Führung der Gewebebahn und damit ein mustergenaues Schneiden erzielt. Die dem Brustbaum nachgeschaltete Fixiervorrichtung ermöglicht optimale Fixierbedingungen, wobei die Führung der einzelnen Bänder nicht mehr kritisch ist.The object is achieved according to the invention by the characterizing features of claim 1. Due to the fact that the guide device and the cutting device are arranged separately from one another on the weaving machine, i.e. So they are not on a common beam, their accessibility is significantly improved, so that they are more easily accessible in the event of malfunctions and adjustment work. Added to this is the fact that these individual devices can be optimally configured individually due to their detached arrangement, for example on the machine frame. Nevertheless, due to the close arrangement of the cutting device on the guide device and thus on the weft thread stop edge, optimal guidance of the fabric web and thus pattern-accurate cutting is achieved. The fixation device located downstream of the breast tree enables optimal fixation conditions, the guidance of the individual ligaments no longer being critical.

Vorteilhafte Ausgestaltungen der Webmaschine sind in den Ansprüchen 2 bis 22 beschrieben.Advantageous embodiments of the weaving machine are described in claims 2 to 22.

Die Webmaschine kann als Führungsvorrichtung ein Umlenkstangensystem gemäss Anspruch 15 aufweisen, vorteilhafter ist jedoch ein Niederhalter gemäss Anspruch 2.The weaving machine can have a deflecting rod system as a guide device according to claim 15, but a hold-down device according to claim 2 is more advantageous.

Dadurch, dass die Gewebebahn lediglich um zwei Führungskanten von zwei Führungsleisten S-förmig geführt wird, ist der Widerstand der Gewebebahn in der Führungsvorrichtung relativ gering, so dass die Gewebebahn in beiden Richtungen durch die Führungsvorrichtung geführt werden kann. Dadurch ergibt sich ein besonders einfacher Aufbau der Führungsvorrichtung, die praktisch nicht staubanfällig ist und für Wartungs- und einstellarbeiten leicht zugänglich ist. Dennoch bietet die S-förmige Führung der Gewebebahn eine ausreichende Niederhaltung und Führung der Gewebebahn an der Schussfadenanschlagkante sowie eine gleichmässige ruhige Führung für den Schneidvorgang, sodass optimale Herstellungsbedingungen für die Gewebebahn bzw. die Bänder gegeben sind.Because the fabric web is guided in an S-shape only around two guide edges by two guide strips, the resistance of the fabric web in the guide device is relatively low, so that the fabric web can be guided through the guide device in both directions. This results in a particularly simple construction of the guide device is practically not susceptible to dust and is easily accessible for maintenance and adjustment work. Nevertheless, the S-shaped guide of the fabric web offers sufficient hold-down and guidance of the fabric web at the weft thread stop edge, as well as uniform, quiet guidance for the cutting process, so that optimal manufacturing conditions for the fabric web or the bands are given.

Die Ausgestaltung nach Anspruch 3 ermöglicht eine gute Anpassung der Führungsleiste an die Gewebebahn und die Ausgestaltung nach Anspruch 4 eine besonders subtile Einstellung der Führungsvorrichtung insbesondere auf die Art der herzustellenden Gewebebahn, beispielsweise deren Dicke.The embodiment according to claim 3 enables a good adaptation of the guide bar to the fabric web and the embodiment according to claim 4 allows a particularly subtle adjustment of the guide device, in particular to the type of fabric web to be produced, for example its thickness.

Besonders gute Führungseigenschaften erzielt man mit einer Ausgestaltung der Führungsvorrichtung nach Anspruch 5. Grundsätzlich kann die erste Führungsleiste so angeordnet sein, dass die Gewebebahn von unten an dieser Führungsleiste anliegt, sodass dann die nutenförmige Ausnehmung und die zweite Führungsleiste über der ersten Führungsleiste angeordnet sind. Vorteilhafter ist es jedoch, wenn die Gewebebahn auf der ersten Führungsleiste aufliegt und nach unten in die nutenförmige Ausnehmung geführt wird, in die auch die zweite entgegen der Laufrichtung der Gewebebahn weisende Führungsleiste eingreift. Das Anpassen der zweiten Führungsleiste mit ihrer zweiten Führungskante an der Art der Gewebebahn und die Produktionsbedingungen können durch eine Ausgestaltung nach Anspruch 6 oder 7 verbessert werden. In gleichem Sinne wirkt auch die Ausgestaltung nach Anspruch 8, wodurch ein etwaiges Klemmen der Gewebebahn an der Führungsvorrichtung einstellbar ist.Particularly good guiding properties are achieved with an embodiment of the guiding device according to claim 5. In principle, the first guiding strip can be arranged in such a way that the fabric web lies against this guiding strip from below, so that the groove-shaped recess and the second guiding strip are then arranged above the first guide strip. However, it is more advantageous if the fabric web rests on the first guide bar and is guided downward into the groove-shaped recess into which the second guide bar pointing counter to the running direction of the fabric web engages. The adaptation of the second guide bar with its second guide edge to the type of fabric web and the production conditions can be improved by an embodiment according to claim 6 or 7. The embodiment according to claim 8 also acts in the same sense, whereby any clamping of the fabric web on the guide device can be set.

Besonders zweckmässig ist eine Ausgestaltung nach Anspruch 9, da dann die hergestellt Gewebebahn mittels der Heizvorrichtung einer ersten Fixierung unterworfen werden kann.An embodiment according to claim 9 is particularly expedient since the fabric web produced can then be subjected to a first fixation by means of the heating device.

Eine Ausgestaltung nach Anspruch 10 und/oder 11 kann zweckmässig sien, um die Gewebebahn in eine gewünschte Form zu bringen. Dabei kann eine vorgesehene Heizvorrichtung an der Führungskante und/oder an der Spreizstange die Fixierung der ausgerichteten Gewebebahn ermöglichen. Das Ausrichten der Gewebebahn an der Spreizstange kann durch die an sich bekannte Ausbildung nach Anspruch 12 weiter gefördert werden. Auch ist es möglich, dass die Spreizstange gemäss Anspruch 13 feststehend angeordnet ist. Aber auch eine angetriebene Ausgestaltungnach Anspruch 14 ist möglich.An embodiment according to claim 10 and / or 11 can expediently in order to bring the fabric web into a desired shape. In this case, a heating device provided on the leading edge and / or on the spreader bar can enable the aligned fabric web to be fixed. The alignment of the fabric web on the spreader bar can be further promoted by the known design according to claim 12. It is also possible for the spreader bar to be arranged in a fixed manner. A driven configuration according to claim 14 is also possible.

Besonders vorteilhaft ist eine Ausbildung der Schneidvorrichtung nach Anspruch 16. Durch die Stellvorrichtung ist es möglich, den Schneidvorgang an den Webprozess, d.h. an die Rapportlänge eines Webmusters in der Gewebebahn anzupassen. So ist beispielsweise beim Etikettenweben die Webgeschwindigkeit und damit auch die Abzugsgeschwindigkeit während des Webens des Musters langsamer als im Bereich zwischen den Mustern. Die Stellvorrichtung ermöglicht es nun, die Schneidköpfe in einer solchen Stellung längs der Gewebebahn einzustellen, dass sie stets dann einen ungemusterten Bereich schneiden, wenn die Webgeschwindigkeit und damit auch die Abzugsgeschwindigkeit grösser ist als im gemusterten Bereich.A design of the cutting device according to claim 16 is particularly advantageous. The adjusting device makes it possible to adapt the cutting process to the weaving process, i.e. to match the repeat length of a weave pattern in the fabric web. For example, in label weaving, the weaving speed and thus the take-off speed during weaving the pattern is slower than in the area between the patterns. The adjusting device now makes it possible to set the cutting heads along the fabric web in such a position that they always cut an unpatterned area when the weaving speed and thus also the take-off speed is greater than in the patterned area.

Besonders vorteilhaft ist eine Fixiervorrichtung gemäss Anspruch 17, die eine einwandfreie Fixierung der hergestellten Bänder ohne wesentliche Formänderungen ermöglicht. Durch die Auflage der Bänder an der rauhen Oberfläche der Walze wird ansich schon ein Verziehen der Bänder in Längswie in Querrichtung verhindert. Die Beibehaltung der Formtreue wird dabei noch durch die Anlage des Heizschuhes unterstützt. Die rauhe Oberfläche der Walze kann beispielsweise durch Ankleben körnigen Materials, wie beispielsweise Korundpulver, Metallpulver und dergleichen erzielt werden. Besonders vorteilhaft ist jedoch eine Ausgestaltung nach Anspruch 18, da das aufgespritzte und angeschmolzene Metallpulver eine innige Verbindung mit der Oberfläche eingeht und deshalb von der durch den Heizschuh bedingten Aufheizung nicht beeinflusst wird. Besonders gute Ergebnisse erhält man mit einer Ausgestaltung nach den Ansprüchen 19 und/oder 20. Besonders zweckmässig ist auch eine Ausbildung nach Anspruch 22.A fixing device according to claim 17 is particularly advantageous, which enables the strips produced to be properly fixed without substantial changes in shape. The fact that the belts rest on the rough surface of the roller prevents warping of the belts in the longitudinal and transverse directions. The retention of shape is supported by the installation of the heating shoe. The rough surface of the roller can be achieved, for example, by adhering granular material, such as corundum powder, metal powder and the like. However, an embodiment according to claim 18 is particularly advantageous since the sprayed and melted metal powder forms an intimate connection with the surface and is therefore not influenced by the heating caused by the heating shoe. Particularly good results are obtained with a configuration according to claims 19 and / or 20. Training according to claim 22 is also particularly expedient.

Besonders vorteilhaft ist eine Ausgestaltung nach Anspruch 22. Da die vorgewärmte Walze insbesondere bei Schnellläufer-Webmaschinen die Fixierung erleichtert.An embodiment according to claim 22 is particularly advantageous, since the preheated roller facilitates fixing, particularly in high-speed weaving machines.

Die Figuren 1 und 2 zeigen in schematischer Darstellung die für die vorliegende Erfindung wesentlichen Teile der Webmaschine. Alle übrigen Teile sind Stand der Technik und hinlänglich bekannt. Es ist das aus Kettfäden (2) gebildete Webfach (4) gezeigt, in das in nicht dargestellter Weise ein Schussfaden (5) eingetragen und mittels eines Webblates (6) an der Anschlagkante (8) der Gewebebahn (10) angeschlagen wird. Die Gewebebahn (10) durchläuft zunächst eine Führungsvorrichtung (12a bzw. 12b) die über die Gewebebahn (10) reicht. Von der Führungsvorrichtung (12a, 12b) gelangt die Gewebebahn (10) zur Abzugsvorrichtung (14a, 14b) mit einer Fixiervorrichtung (16a, 16b), der eine Schneidvorrichtung (18) vorgelagert ist. Die Führungsvorrichtung (12a, 12b), die Schneidvorrichtung (18) sowie die Fixiervorrichtung (16a, 16b) sind unabhängig und mit Abstand voneinander am Gestell der Webmaschine angeordnet.Figures 1 and 2 show a schematic representation of the parts of the loom essential for the present invention. All other parts are state of the art and well known. The weaving shed (4) formed from warp threads (2) is shown, into which a weft thread (5) is inserted in a manner not shown and is attached to the stop edge (8) of the fabric web (10) by means of a weaving blade (6). The fabric web (10) first passes through a guide device (12a or 12b) which extends over the fabric web (10). From the guide device (12a, 12b) the fabric web (10) reaches the take-off device (14a, 14b) with a fixing device (16a, 16b), which is preceded by a cutting device (18). The guide device (12a, 12b), the cutting device (18) and the fixing device (16a, 16b) are arranged independently and at a distance from one another on the frame of the weaving machine.

Die Schneidvorrichtung (18) ist wiederum in bekannter Weise ausgestaltet und enthält verschiedene Schneidköpfe (20) mit Schneidelementen (22), die entsprechend der gewünschten Breite der herzustellenden Bänder einzeln quer zur Gewebebahn eingestellt werden. Die Schneidköpfe können elektrisch heizbare Schneiddrähte oder Schneidklingen aufweisen. Auch Schneidköpfe mit Ultraschallschneidelementen oder Laserschneidelementen sind möglich. In jedem Falle sind die Schneidelemente so ausgestaltet, dass sie nicht nur ein Schneiden der Gewebebahn, d.h. praktisch ein Durchtrennen der Schussfäden zwischen zwei Kettfäden ermöglichen, sondern gleichzeitig auch noch für ein aufriffelfestes Anschmelzen der Schneidkanten sorgen. Die Gewebebahn besteht hierzu mindestens teilweise aus thermoplastischen Garnen. Zur Synchronisation des Schneidvorganges mit einem Musterrapport sind die Schneidköpfe (20) über Stellspindeln (26) mit einem Support (28) verbunden und können so in ihrer Stellung in Richtung der Kettfäden, d.h. in der Laufrichtung der Gewebebahn eingestellt werden. Dadurch ist eine Synchronisation des Schneidvorganges mit dem Musterrapport der Gewebebahn möglich.The cutting device (18) is in turn designed in a known manner and contains various cutting heads (20) with cutting elements (22) which are individually set transversely to the fabric web in accordance with the desired width of the strips to be produced. The cutting heads can have electrically heated cutting wires or cutting blades. Cutting heads with ultrasonic cutting elements or laser cutting elements are also possible. In any case, the cutting elements are designed in such a way that they do not only cut the fabric web, ie practically cut it through enable the weft threads between two warp threads, but at the same time also ensure that the cutting edges are melted on without interruption. For this purpose, the fabric web consists at least partially of thermoplastic yarns. To synchronize the cutting process with a pattern repeat, the cutting heads (20) are connected to a support (28) via adjusting spindles (26) and can thus be adjusted in their position in the direction of the warp threads, ie in the running direction of the fabric web. This enables the cutting process to be synchronized with the pattern repeat of the fabric web.

In der Webmaschine der Figur 1 ist die Führungsvorrichtung (12a) als Umlenkstangensystem ausgebildet, wobei die Gewebebahn (10) um drei ortsfeste, mit dem Maschinengestell (30) verbundene Stangen (32, 34, 36) geführt ist. Mindestens eine Stange kann drehbar und mindestens eine Stange kann beheizbar ausgebildet sein, um eine Vorfixierung der Gewebebahn zu ermöglichen.In the weaving machine in FIG. 1, the guide device (12a) is designed as a deflecting rod system, the fabric web (10) being guided around three fixed rods (32, 34, 36) connected to the machine frame (30). At least one rod can be rotated and at least one rod can be designed to be heatable in order to enable the fabric web to be pre-fixed.

Die Abzugsvorrichtung (14a) der Webmaschine der Fig. 1 enthält, wie erwähnt, gleichzeitig auch die Fixiervorrichtung (12a) für die hergestellten Bänder. Hierzu ist die Abzugswalze (38) mit einer aufgerauhten Oberfläche versehen, die beispielsweise durch aufgespritztes und angeschmolzenes Metallpulver gebildet ist. Die einzelnen Bänder werden über die eingangsseitige, als Brustbaum (40) dienende Führungswalze und die abgangsseitige Führungswalze (42), welche die Auflauf- und die Ablaufstellen bestimmen an der Abzugswalze (38) zur Anlage gebracht. Mit der Abzugswalze (38) wirkt ein gegen die Abzugswalze (38) zustellbarer Heizschuh (44) zusammen, der ebenfalls über die Gewebebahn reicht, zwischen der Auflauf- und oder Ablaufstelle der geschnittenen Gewebebahn, vorzugsweise beim halben Umschlingungswinkel (nicht dargestellt) der Gewebebahn liegt und eine der Umfangsfläche der Abzugswalze (38) angepasste Kontaktfläche (46) besitzt. Dieser Heizschuh (44) ist über Federn (48) elastisch mit einem Zustellglied (50) verbunden, sodass sich eine optimale Anschmiegung des Heizschuhes (44) an die auf der Absugswalze liegenden, zu fixierenden Bänder ergibt. Das Zustellglied (50) ist mit einer Stellvorrichtung (52) verbunden. Der Heizschuh (44) kann wiederum mit einer elektrischen Widerstandsheizung ausgestattet sein sowie mit Fühlern und Reglern zur Einstellung der notwendigen Fixiertemperatur die vorzugsweise mindestens 130°C beträgt. Auch die Stellvorrichtung (52) kann an eine Steuereinheit angeschlossen sein, um die Vorspannkraft des Heizschuhes (44) einstellen zu können.The draw-off device (14a) of the weaving machine in FIG. 1 also contains, as mentioned, the fixing device (12a) for the tapes produced. For this purpose, the take-off roller (38) is provided with a roughened surface, which is formed, for example, by sprayed and melted metal powder. The individual belts are brought into contact with the take-off roller (38) via the guide roller on the input side serving as the breast beam (40) and the guide roller (42) on the outlet side, which determine the run-up and drain points. A heating shoe (44) which can be set against the removal roller (38) interacts with the removal roller (38), which also extends over the fabric web, lies between the run-up and / or drain point of the cut fabric web, preferably at half the wrap angle (not shown) of the fabric web and has a contact surface (46) adapted to the peripheral surface of the take-off roller (38). This heating shoe (44) is connected elastically to a feed element (50) via springs (48), so that the heating shoe (44) is optimally nestled against the belts to be fixed on the suction roller. The feed member (50) is connected to an actuating device (52). The heating shoe (44) can in turn be equipped with an electrical resistance heater and with sensors and controllers for setting the necessary fixing temperature, which is preferably at least 130 ° C. The adjusting device (52) can also be connected to a control unit in order to be able to set the pretensioning force of the heating shoe (44).

Die Webmaschine der Fig. 2 unterscheidet sich von der Webmaschine der Fig. 1 dadurch, dass die Führungsvorrichtung (12b) als Niederhalter ausgebildet ist, der in den Figuren 3 und 4 nachfolgend näher erläutert wird. Ausserdem ist die Gewebebahn nach der Schneidvorrichtung (18) und vor der Abzugsvorrichtung (14b) über einen als Platte ausgebildeten Brustbaum (54) geführt, der die Funktion des Brustbaumes (40) der Fig. 1 übernimmt. Die Abzugswalze (38a) ist vorzugsweise auf eine Temperatur<100° C beheizbar, um die zu fixierenden Bänder vorzuwärmen, um die Fixierung an der Fixiervorrichtung (16b) zu beschleunigen. Letztere ist zweckmässigerweise analog der Fixiervorrichtung (16a) der Fig. 1 ausgebildet und auf eine Temperatur>130° C beheizbar. Die Fixiervorrichtung (16a) kann, wie in Fig. 1 an der Abzugswalze (38a) angreifen oder wie im gezeigten Beispiel an der nachgeordneten Führungswalze (42).The loom of FIG. 2 differs from the loom of FIG. 1 in that the guide device (12b) is designed as a hold-down device, which is explained in more detail in FIGS. 3 and 4 below. In addition, the fabric web is guided after the cutting device (18) and before the take-off device (14b) via a breast tree (54) designed as a plate, which takes over the function of the breast tree (40) of FIG. 1. The take-off roller (38a) can preferably be heated to a temperature <100 ° C. in order to preheat the belts to be fixed in order to accelerate the fixing to the fixing device (16b). The latter is expediently designed analogously to the fixing device (16a) in FIG. 1 and can be heated to a temperature> 130.degree. The fixing device (16a) can act on the draw-off roller (38a) as in FIG. 1 or on the downstream guide roller (42) as in the example shown.

Die Fig. 3 zeigt eine erste, als Niederhalter ausgebildete Führungsvorrichtung (12b) an der Webstelle der Webmaschine. Die Kettfäden (2) sind mittels einer nicht dargestellten Fachbildvorrichtung so geführt, dass das offene Webfach (4) gebildet wird, durch das der Schussfaden (5) eingetragen und mittels des Webblattes (6) an der Anschlagkante (8) der Gewebebahn (10) angeschlagen wird. Die Führungsvorrichtung (12b) enthält eine erste Führungsleiste (56), auf deren Oberseite die Gewebebahn (10) aufliegt. Die Führungsleiste besitzt eine in Laufrichtung (58) der Gewebebahn (10) weisende Führungskante (60), über die die Gewebebahn in eine darunterliegende nutenartige Ausnehmung (62) geführt ist. Hierzu dient die gerundete Führungskante (64) einer zweiten Führungsleiste (66), die die Gewebebahn (10) in die Ausnehmung (62) einführt, sodass die Gewebebahn S-förmig geführt ist. Nach der zweiten Führungskante (64) wird die Gewebebahn (10) über eine Spreizstange (68) weiter transportiert. Die Spreizstange (68) liegt unter der zweiten Führungsleiste (66) und ist vorzugsweise in nicht näher dargestellter bekannter Weise auf einer Hälfte mit einem Rechtsgewinde und auf der anderen Hälfte mit einem Linksgewinde versehen, um die Gewebebahn in Richtung quer zur Gewebebahn zu spannen. Entsprechende Gewinderillen können auch an der ersten und/oder zweiten Führungskante (60, 64) vorhanden sein. Die Spreizstange (68) kann ruhend angeordnet sein, wie im gezeigten Beispiel, oder angetrieben, wobei dann die Umfangsgeschwindigkeit grösser sein muss als die Produktionsgeschwindigkeit der Gewebebahn. Auch ein gegenläufiger Antrieb ist möglich. Die Spreizstange (68) ist jedoch im vorliegenden Beispiel stillstehend und mittels einer Schraube (70) an einem Träger (72) befestigt, der auch die erste Führungsleiste (56) trägt. Die zweite Führungsleiste (66) ist an der Spreizstange (68) verschwenkbar gelagert, wobei die Achse (74) der Spreizstange, welche auch die Schwenkachse der zweiten Führungsleiste (66) bildet, parallel zur Führungskante (60) bzw. (64) liegt. Die zweite Führungsleiste (66) ist unter einem spitzen Winkel (α) zur Ebene (76) der Gewebebahn (10) an der Anschlagkante (8) geneigt, wodurch ein Klemmen der Gewebebahn (10) zwischen den Führungskanten (60, 64) der ersten Führungsleiste (56) und der zweiten Führungsleiste (66) beim Abziehen der Gewebebahn einstellbar ist.3 shows a first guiding device (12b) in the form of a hold-down device at the weaving machine's weaving machine. The warp threads (2) are guided by means of a shedding device (not shown) in such a way that the open shed (4) is formed, through which the weft thread (5) is inserted and by means of the reed (6) on the stop edge (8) of the fabric web (10) is struck. The guide device (12b) contains a first guide bar (56), on the top of which the fabric web (10) rests. The guide strip has a guide edge (60) which points in the running direction (58) of the fabric web (10) and via which the fabric web is guided into a groove-like recess (62) underneath. The rounded guide edge (64) of a second guide bar (66), which introduces the fabric web (10) into the recess (62), is used for this purpose, so that the fabric web is guided in an S-shape. After the second leading edge (64), the fabric web (10) is transported further via a spreader bar (68). The spreader bar (68) lies under the second guide bar (66) and is preferably provided in a known manner, not shown, on one half with a right-hand thread and on the other half with a left-hand thread in order to tension the fabric web in the direction transverse to the fabric web. Corresponding thread grooves can also be present on the first and / or second guide edge (60, 64). The spreader bar (68) can be arranged to be stationary, as in the example shown, or driven, in which case the peripheral speed must be greater than the production speed of the fabric web. A reverse drive is also possible. In the present example, however, the spreader bar (68) is stationary and is fastened by means of a screw (70) to a support (72) which also carries the first guide bar (56). The second guide bar (66) is pivotally mounted on the spreader bar (68), the axis (74) of the spreader bar, which also the Forms pivot axis of the second guide bar (66), is parallel to the guide edge (60) or (64). The second guide bar (66) is inclined at an acute angle (α) to the plane (76) of the fabric web (10) on the stop edge (8), causing the fabric web (10) to jam between the guide edges (60, 64) of the first Guide bar (56) and the second guide bar (66) when pulling off the fabric web is adjustable.

Die zweite Führungsleiste (66) enthält mindestens im Bereich der Führungskante (64) eine Heizvorrichtung (78) zum Fixieren der Gewebebahn, d.h. zur Stabilisierung der Schuss- und/oder Kettfäden. Die Heizwirkung kann sich bis zur Spreizstange (68) fortsetzen und durch eine isolierende Abdeckung (80) über der zweiten Führungsleiste (66) unterstützt werden. Für bestimmte Bedingungen kann auch die Spreizstange beheizbar sein.The second guide bar (66) contains at least in the area of the guide edge (64) a heating device (78) for fixing the fabric web, i.e. to stabilize the weft and / or warp threads. The heating effect can continue up to the spreader bar (68) and be supported by an insulating cover (80) over the second guide bar (66). The spreader bar can also be heated for certain conditions.

Die in Fig. 4 dargestellte Führungsvorrichtung (12b) entspricht jener der Fig. 3, sodass gleiche Teile mit den gleichen Bezugszeichen sind. Im Gegensatz zur Führungsvorrichtung der Fig. 3 ist bei jener der Fig. 4 die zweite Führungsleiste (66a) an Auflagern (82) angeordnet, die mit dem Träger (72) verbunden sind. Die Auflager tragen auch die Spreizstange (68). Die Führungsleiste (66a) ist an den Auflagern (82) in Laufrichtung (58) der Gewebebahn mittels Einstellschrauben (84) verstellbar geführt, sodass die Ueberlappungstiefe(x) der hintereinandergreifenden Führungsleisten (66a, 60) einstellbar ist. In der jeweils eingestellten Ueberlappungstiefe(x) ist die Führungsleiste mittels der Fixierschraube (86) feststellbar. Die zweite Führungskante (64a) ist mittels eines federnden Halters (88) an der zweiten Führungsleiste (66a) befestigt, sodass die zweite Führungskante (64a) um eine durch die Einspannstelle (90) gegebene Achse (74a) schwenkbar ist.The guide device (12b) shown in FIG. 4 corresponds to that of FIG. 3, so that the same parts have the same reference numerals. In contrast to the guide device of FIG. 3, in that of FIG. 4 the second guide bar (66a) is arranged on supports (82) which are connected to the carrier (72). The supports also carry the spreader bar (68). The guide bar (66a) is adjustably guided on the supports (82) in the running direction (58) of the fabric web by means of adjusting screws (84) so that the depth of overlap (x) of the guide bars (66a, 60) engaging one behind the other can be adjusted. The guide bar can be locked in the set overlap depth (x) by means of the fixing screw (86). The second guide edge (64a) is fastened to the second guide bar (66a) by means of a resilient holder (88), so that the second guide edge (64a) can be pivoted about an axis (74a) given by the clamping point (90).
