Description

Die Erfindung betrifft eine Vorrichtung zum Mercerisieren einer textilen Gewebebahn gemäss dem Oberbegriff von Anspruch 1.The invention relates to a device for mercerizing a textile fabric web according to the preamble of claim 1.

Durch die Führung der Gewebebahn vom Heisslaugenbad bis zum Spannrahmen auf zylindrischen Walzen bei gebundener Gewebeführung wird eine unkontrollierte und übermässige Gewebeschrumpfung vermieden. Eine gattungsmässig vergleichbare Vorrichtung ist durch die EP-A-198 793 der Anmelderin bekannt geworden. Ein Problem bei der gebundenen Gewebebahnführung bis zum Spannrahmeneinlauf besteht darin, dass die Zugänglichkeit zum Einführen der Gewebebahn in den Spannrahmen erschwert ist. Gerade in dieser Uebergangszonewäre es jedoch wünschenswert, eine optimale Zugänglichkeit zu schaffen, um beim Maschinenstart die Gewebebahn leicht in den Spannrahmen einführen zu können, oder um bei Betriebsstörungen wie z.B. bei Breitenveränderungen des Gewebes sofort eingreifen zu können.Uncontrolled and excessive shrinkage of the fabric is avoided by guiding the fabric web from the hot-water bath to the tenter frame on cylindrical rollers with bound fabric guidance. A generic comparable device has become known from the applicant's EP-A-198 793. A problem with the bound fabric web guide up to the stenter entry is that the accessibility for inserting the fabric web into the stenter is difficult. In this transition zone in particular, however, it would be desirable to provide optimum accessibility so that the fabric web can be easily inserted into the stenter frame when the machine is started, or in the event of malfunctions such as to be able to intervene immediately when the width of the fabric changes.

Es ist daher eine Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der eine optimale Zugänglichkeit am Spannrahmeneinlauf gewährleistet ist, ohne dass dabei eine unzulässig lange freie Gewebebahnstrecke geschaffen wird. Eine weitere Aufgabe der Erfindung besteht ausserdem darin, den Zugang zu einzelnen Stellen der Einwirkzone insgesamt zu erleichtern. Diese Aufgabe wird erfindungsgemäss mit einer Vorrichtung gelöst, welche die Merkmale im Anspruch 1 aufweist. Der Bedienungsstand mit der unterhalb des Spannrahmeneinlaufs liegenden Standfläche ermöglicht ersichtlicherweise ein Hantieren am Spannrahmeneinlauf über die gesamte Breite der Gewebebahn und in einer bequemen Arbeitshöhe. Die Bedienungsperson wird dabeinicht gefährdet, so dass der Bedienungsstand auch bei laufender Maschine betreten werden kann. Bei geeigneter Ausbildung des Bedienungsstandes sind auch weitere Abschnitte der Einwirkzone jederzeit leicht zugänglich bzw. können diese Abschnitte leicht beobachtet werden.It is therefore an object of the invention to provide a device of the type mentioned in the introduction, in which optimal accessibility at the stenter inlet is ensured without creating an impermissibly long free fabric path. Another object of the invention is to facilitate access to individual locations in the zone of action as a whole. This object is achieved according to the invention with a device which has the features in claim 1. The control station with the base area below the stenter inlet clearly allows handling of the stenter inlet over the entire width of the fabric web and at a comfortable working height. The operator is not endangered, so that the operator station can be entered even when the machine is running. With a suitable design of the control station, other sections of the zone of action are easily accessible at all times or these sections can be easily observed.

Vorzugsweise bilden die Walzen im Bereich des Bedienungsstandes einen bogenförmigen Umfahrungsabschnitt, so dass die Gewebebahn den Bedienungsstand kreisbogenähnlich umfährt. Der bogenförmige Umfahrungsabschnitt hat nicht nur den Vorteil, dass vom Bedienungsstand aus praktisch die gesamte Einwirkzone leicht zugänglich ist, sondern er verkürzt infolge der Bogenform auch die Gesamtlänge der Anlage.The rollers preferably form an arc-shaped bypass section in the area of the operating station, so that the fabric web bypasses the operating station like an arc. The arched bypass section not only has the advantage that practically the entire impact zone is easily accessible from the control station, but it also shortens the overall length of the system due to the arch shape.

Der bogenförmige Umfahrungsabschnitt besteht dabei vorteilhaft aus wechselweise angeordneten, fest gelagerten Fixwalzen und verschiebbar gelagerten Walzen. Eine kontinuierliche gebundene Bahnführung lässt sich so besonders einfach realisieren, wobei die einzelnen Walzen zum Einführen der Gewebebahn oder bei Ruhestellung der Anlage voneinander abgehoben werden können. Die verschiebbar gelagerten Walzen können dabei Zustellwalzen sein, deren Achsen mit gelenkig gelagerten Druckmittelzylindern verbunden sind.The arcuate bypass section advantageously consists of alternately arranged, fixed fixed rollers and slidably mounted rollers. Continuously bound web guidance can be realized particularly easily in this way, whereby the individual rollers can be lifted from one another for the insertion of the fabric web or when the system is at rest. The slidably mounted rollers can be feed rollers, the axes of which are connected to articulated pressure medium cylinders.

Der Uebergang in den Spannrahmeneinlauf wird vorteilhaft so ausgebildet, dass das Ende des bogenförmigen Umfahrungsabschnitts durch zwei Zustellwalzen gebildet wird, von denen die in Vorschubrichtung letzte von schräg unten gegen eine über der Spannrahmenebene gelagerte Fixumlenkwalze pressbar ist. Die Fixumlenkwalze kann relativ nahe am Einlaufbereich des Spannrahmens angeordnet sein, wobei sie vom Bedienungsstand aus gut zugänglich ist. Die zwei im Betrieb aneinanderliegenden Zustellwalzen am Ende des bogenförmigen Umfahrungsabschnittes ermöglichen ein Hochziehen der Gewebebahn bei gebundener Bahnführung.The transition into the stenter inlet is advantageously designed such that the end of the arcuate bypass section is formed by two feed rollers, the last of which in the feed direction can be pressed obliquely from below against a fixed deflecting roller mounted above the stenter plane. The fixed deflecting roller can be arranged relatively close to the inlet area of the stenter, whereby it is easily accessible from the control station. The two feed rollers lying against each other during operation at the end of the curved bypass section enable the fabric web to be pulled up with the web guide bound.

Der Anfang des bogenförmigen Umfahrungsabschnittes kann durch eine abhebbare Aufliegewalze gebildet sein, die auf einer Fixwalze aufliegt. Die Aufliegewalze ist somit das Gegenstück zur letzten Zustellwalze am Ende des bogenförmigen Umfahrungsabschnittes. Da die Gewebebahn am Anfang des Umfahrungsabschnitts nach unten geführtwerden muss, wird deren Spannung bzw. die gebundene Bahnführung jedoch durch das Eigengewicht der Aufliegewalze gewährleistet.The beginning of the arcuate bypass section can be formed by a lifting roller which can be lifted off and which rests on a fixed roller. The lay-on roller is thus the counterpart to the last feed roller at the end of the curved bypass section. Since the fabric web must be led down at the beginning of the bypass section, its tension or the bound web guidance is guaranteed by the weight of the lay-on roller.

Der Bedienungsstand besteht vorzugsweise aus aufklappbaren Abschnitten, die mit Gasfedern verbunden sind. Diese Ausbildung erhöht die Betriebssicherheit und gewährleistet trotzdem eine optimale Zugänglichkeit aller Abschnitte der Einwirkzone. Um auch bei aufgeklappten Abschnitten ein Begehen des Betriebsstandes zu ermöglichen, kann an der tiefsten Stelle wenigstens ein feststehender Quersteg vorgesehen sein.The control station preferably consists of hinged sections that are connected with gas springs. This training increases operational safety and still ensures optimal access to all sections of the zone of action. In order to enable access to the operating status even when the sections are open, at least one fixed crosspiece can be provided at the lowest point.

Ein Ausführungsbeispiel der Erfindung wird nachstehend beschrieben und in den Zeichnungen genauer dargestellt. Es zeigen:

  • Figur 1 einen Querschnitt durch eine Mercerisiermaschine mit den erfindungsgemässen Merkmalen,
  • Figur 2 die Einwirkzone gemäss Figur 1 in etwas vergrösserter Darstellung, und
  • Figur 3 die Einwirkzone gemäss Figur 2, jedoch mit abgehobenen Walzen.
An embodiment of the invention is described below and shown in more detail in the drawings. Show it:
  • FIG. 1 shows a cross section through a mercerizing machine with the features according to the invention,
  • Figure 2 shows the exposure zone according to Figure 1 in a somewhat enlarged representation, and
  • Figure 3 shows the exposure zone according to Figure 2, but with the rollers raised.

Figur 1 zeigt eine vom prinzipiellen Aufbau her an sich bekannte Mercerisiermaschine 1, bei der eine Gewebebahn 2 in gebundener Bahnführung nacheinander eine Heissimprägnierzone 3, eine Kühlzone 4, eine Einwirkzone 5 und eine Stabilisierzone 6 durchläuft, wobei anschliessend die mercerisierte und stabilisierte Gewebebahn in der nicht mehr dargestellten Waschmaschine ausgewaschen und neutralisiert wird.FIG. 1 shows a mercerizing machine 1 which is known per se in terms of its basic construction, in which a fabric web 2 in bound web guidance passes successively through a hot impregnation zone 3, a cooling zone 4, an action zone 5 and a stabilization zone 6, the mercerized and stabilized fabric web subsequently not in the more washing machine shown is washed out and neutralized.

Die Stabilisierzone 6 besteht aus zwei Abschnitten, nämlich aus der Breitstreckzone 7, gebildet durch den Spannrahmen 8, und aus einer anschliessenden Walzenzone 9. In der Stabilisierzone 6 wird die Gewebebahn 2 in bekannter Art und Weise über Spritzrohre 10 mit heisser Schwachlauge im Gegenstrom beaufschlagt, entlaugt und stabilisiert. Dabei wird die Gewebebahn 2 in der Breitstreckzone 7 mittels eines Spannrahmens 8 in die gewünschte Breite gebracht und derart gestreckt der Walzenzone 9 übergeben. Im vorliegenden Ausführungsbeispiel ist der Spannrahmen 8 ein Nadelspannrahmen. Grundsätzlich wären aber auch andere Typen von Spannrahmen oder Breitstreckvorrichtungen denkbar.The stabilization zone 6 consists of two sections, namely the spreader zone 7, formed by the tenter frame 8, and a subsequent roller zone 9. In the stabilization zone 6, the fabric web 2 acted upon in a known manner via spray tubes 10 with hot weak liquor in countercurrent, de-leached and stabilized. The fabric web 2 in the spreader zone 7 is brought into the desired width by means of a tensioning frame 8 and, in such a stretched manner, is transferred to the roller zone 9. In the present embodiment, the clamping frame 8 is a needle clamping frame. In principle, however, other types of stenter frames or spreader devices would also be conceivable.

Vor dem Spannrahmeneinlauf ist über der Einwirkzone 5 ein Bedienungsstand 13 angeordnet, der sich vorzugsweise über die gesamte Breite der Mercerisiermaschine erstreckt und der eine Standfläche aufweist, welche tiefer liegt als der Einlauf des Spannrahmens. Auf diese Weise kann eine Bedienungsperson 12 den Bedienungsstand 13 betreten und aus einer bequemen Arbeitsposition die Einführung der Gewebebahn 2 in den Spannrahmen 8 überwachen bzw. bei einem neuen Gewebeeinzug den gesamten Bereich der Gewebeeinführung 11 erreichen. Der Bedienungsstand 13 wird dabei von der Gewebebahn 2 ohne freie Gewebestrecke in gebundener Bahnführung auf den Walzen umfahren. Diese Umfahrungsstrecke bildet dabei einen integrierenden Bestandteil der Einwirkzone 5, wobei infolge der bogenförmigen Vorschubbahn die Gesamtlänge der Mercerisiermaschine 1 reduziert werden kann.In front of the stenter inlet, an operating station 13 is arranged above the action zone 5, which preferably extends over the entire width of the mercerizing machine and has a footprint which is lower than the inlet of the stenter. In this way, an operator 12 can enter the control station 13 and monitor the introduction of the fabric web 2 into the tensioning frame 8 from a comfortable working position, or can reach the entire area of the tissue insertion 11 with a new tissue intake. The control station 13 is bypassed by the fabric web 2 without a free fabric stretch in a bound web guide on the rollers. This bypass route forms an integral part of the action zone 5, the total length of the mercerizing machine 1 being able to be reduced as a result of the curved feed path.

Die Einwirkzone 5 beginnt mit einer Quetsche 14, bestehend aus einer unteren festen Antriebswalze 15 und aus einer oberen Quetschwalze 16, die auf bekannte Weise gegen die Antriebswalze pressbar ist. Nach der Quetsche 14 wird die Gewebebahn 2 von einer Gewebezugreglerwalze 17 aufgenommen, die auf an sich bekannte Weise an einem Gestänge 18 angelenkt ist und die eine Regelung des gewünschten Gewebezugs mit Hilfe des Druckmittelzylinders 19 erlaubt. Dabei wird das Eigengewicht der Gewebezugreglerwalze 17 zur Erzeugung des Gewebezuges verwendet, wobei dieses Eigengewicht über den Zylinder 19 reduziert werden kann, so dass auch kleinstmögliche Gewebezüge gefahren werden können.The action zone 5 begins with a squeeze 14, consisting of a lower fixed drive roller 15 and an upper squeeze roller 16, which can be pressed against the drive roller in a known manner. After the squeeze 14, the fabric web 2 is taken up by a fabric tension regulator roller 17 which is articulated on a linkage 18 in a manner known per se and which allows the desired fabric tension to be regulated with the aid of the pressure medium cylinder 19. The dead weight of the fabric tension regulator roller 17 is used to generate the fabric tension, whereby this dead weight can be reduced via the cylinder 19, so that even the smallest possible fabric tension can be traversed.

Im Anschluss an die Gewebezugreglerwalze 17 folgt eine Aufliegewalze 20, die einerseits je nach der Stellung der Gewebezugreglerwalze 17 immer an dieser anliegt und sich andererseits auf einer ersten fest gelagerten Fixwalze 21a abstützt. Die Aufliegewalze 20 kann auf an sich bekannte Weise mit Hilfe eines Exzenters 29 pneumatisch oder manuell angehoben werden.The fabric tension regulator roller 17 is followed by a lay-on roller 20 which, depending on the position of the fabric tension regulator roller 17, always bears against it and which is supported on a first fixed roller 21a. The lay-on roller 20 can be lifted pneumatically or manually in a manner known per se with the aid of an eccentric 29.

Die Gewebebahn 2 umschlingt die Aufliegewalze 20 und die erste Fixwalze 21a und wird derart vor dem Bedienungsstand 13 nach unten geführt. Anschliessend folgt eine erste Zustellwalze 22a, die mit beidseitig angeordneten Pneumatikzylindern 23a verbunden ist, welche am Gestell angelenkt sind. Mit Hilfe der Zustellwalze 22a kann die Gewebebahn zwischen die vorgelagerte Fixwalze 21a und die nachfolgende Fixwalze 21 b gepresst werden, so dass sie an beiden Fixwalzen 21 und 21 b anliegt.The fabric web 2 wraps around the lay-on roller 20 and the first fixed roller 21a and is thus guided downwards in front of the operating station 13. This is followed by a first feed roller 22a, which is connected to pneumatic cylinders 23a which are arranged on both sides and which are articulated on the frame. With the help of the feed roller 22a, the fabric web can be pressed between the upstream fixed roller 21a and the subsequent fixed roller 21b, so that it rests on both fixed rollers 21 and 21b.

Auf die gleiche Weise wird die Gewebebahn durch eine zweite Zustellwalze 22b zwischen die zweite Fixwalze 21 b und eine dritte Fixwalze 21c gepresst, wobei lediglich die Kraftrichtung des Pneumatikzylinders 23b entsprechend der Relativlage der Fixwalzen 21 b und 21 etwas abgeändert ist. Beim Pneumatikzylinder 23a verläuft die Kraftrichtung in einem etwa spitzen Winkel gegen die Senkrechte, während die Kraftrichtung beim Pneumatikzylinder 23b praktisch senkrecht verläuft. Nach der Umschlingung der Fixwalze 21c wird die Gewebebahn 2 wiederum nach oben geführt, indem eine dritte Zustellwalze 22c mit Hilfe des Pneumatikzylinders 23c etwa horizontal seitlich gegen die dritte Fixwalze 21 c gepresst wird. Nach der dritten Zustellwalze 22c folgt jedoch keine Fixwalze, sondern eine weitere, vierte und letzte Zustellwalze 22d mit Pneumatikzylinder 23d, die von schräg unten gegen eine über der Ebene des Spannrahmens liegende, fest gelagerte Fixumlenkwalze 24 pressbar ist. Die Gewebebahn 2 ist somit mittels der Zustellwalze 22c gegen die dritte Fixwalze 21c und gegen die letzte Zustellwalze 22d pressbar und mit letzterer gleichzeitig gegen die Fixumlenkwalze 24. Auf diese Weise ist auch im aufsteigenden Abschnitt der Vorschubstrecke eine gebundene Bahnführung gewährleistet.In the same way, the fabric web is pressed by a second feed roller 22b between the second fixed roller 21b and a third fixed roller 21c, only the direction of force of the pneumatic cylinder 23b being changed somewhat in accordance with the relative position of the fixed rollers 21b and 21. In the pneumatic cylinder 23a, the direction of force is at an approximately acute angle to the vertical, while the direction of force in the pneumatic cylinder 23b is practically perpendicular. After the fixed roller 21c has been wrapped around, the fabric web 2 is again guided upward by pressing a third feed roller 22c approximately horizontally laterally against the third fixed roller 21c with the aid of the pneumatic cylinder 23c. However, the third feed roller 22c is not followed by a fixed roller, but by a further, fourth and last feed roller 22d with a pneumatic cylinder 23d, which can be pressed obliquely from below against a fixed deflection roller 24 lying above the plane of the tenter frame. The fabric web 2 can thus be pressed against the third fixed roller 21c and against the last feed roller 22d by means of the feed roller 22c and at the same time against the fixed deflection roller 24 with the latter. In this way, a bound web guide is also ensured in the ascending section of the feed path.

Bei entlasteten Pneumatikzylindern kommen die Zustellwalzen 22a bis 22d an Anschlägen 30b bis 30f zum Anliegen. Im Falle der Zustellwalze 22d ist der Anschlag 30f derart beidseitig ausgebildet, dass die Walze sowohl im belasteten als auch im entlasteten Zustand am Anschlag anliegt. Aufgrund der Stellung des Pneumatikzylinders 23b ist auch an der Zustellwalze 22b ein Doppelanschlag 30c vorgesehen. Dagegen genügt bei den Zustellwalzen 22a und 22c infolge der Position der Pneumatikzylinder 23a und 23c ein einfacher Anschlag 30b bzw. 30d.When the pneumatic cylinders are relieved, the feed rollers 22a to 22d come to rest against stops 30b to 30f. In the case of the feed roller 22d, the stop 30f is formed on both sides in such a way that the roller rests against the stop both in the loaded and in the released state. Due to the position of the pneumatic cylinder 23b, a double stop 30c is also provided on the feed roller 22b. In contrast, a simple stop 30b or 30d is sufficient for the feed rollers 22a and 22c due to the position of the pneumatic cylinders 23a and 23c.

Von der Fixumlenkwalze 24 wird die Gewebebahn 2 über die relativ kurze freie Strecke 25 der Aufnadelwalze 26 übergeben und wird dort dem Spannrahmen 8 zugeführt. Der Spannrahmen wird auf an sich bekannte Weise durch ein Spannkettenpaar 27 gebildet, dessen Kettenglieder 27a mit Nadeln 27b versehen sind. Die Nadeln nehmen die Gewebebahn 2 auf, wobei diese durch die konisch auseinanderlaufenden Spannketten in die Breite gespannt wird. Die Spannketten 27 werden über Kettenräder 28 angetrieben.The fabric web 2 is transferred from the fixed deflecting roller 24 over the relatively short free distance 25 to the needle roller 26 and is fed there to the tensioning frame 8. The tensioning frame is formed in a manner known per se by a pair of tensioning chains 27, the chain links 27a of which are provided with needles 27b. The needles take up the fabric web 2, which is stretched in width by the conically diverging tension chains. The tension chains 27 are driven via chain wheels 28.

Der Bedienungsstand 13 besteht aus aufklappbaren Abschnitten 31a und 31 b, welche mit Gasfedern 33a und 33b verbunden sind. Die Gasfedern erleichtern der Bedienungsperson das Aufklappen der Abschnitte. Der aufklappbare Abschnitt 31 bist am festen Abschnitt 31c angelenkt, wobei der Abschnitt 31 b aus einem Bodenteil und aus einem Seitenteil besteht, welche gelenkig miteinander verbunden sind. Um den Bedienungsstand 13 auch im geöffneten Zustand betreten zu könen, ist an der tiefsten Stelle ein fester Quersteg 32 angeordnet, welcher schmaler ist als die Gesamtbreite des Bedienungsstandes.The control station 13 consists of hinged sections 31a and 31b, which are connected to gas springs 33a and 33b. The gas springs make it easier for the operator to open the sections. The hinged section 31 is hinged to the fixed section 31c, the section 31b consisting of a bottom part and a side part which are connected to one another in an articulated manner. To the control station 13 To be able to enter even in the open state, a fixed crosspiece 32 is arranged at the deepest point, which is narrower than the total width of the operating station.

Eine Bedienungsperson 12 kann vom geschlossenen Bedienungsstand 13 aus die Gewebebahn im Bereich der Fixumlenkwalze 24 bzw. derfreien Strecke 25 einwandfrei beobachten und dabei auch die korrekte Aufnadelung der Gewebebahn 2 auf die Nadeln 27b überprüfen und evtl. korrigierend eingreifen. Auch bei aufgeklappten Abschnitten hat die Bedienungsperson vom Quersteg 32 aus freien Zugang zu allen im Bereich der Gewebeeinführung 11 liegenden Walzen.An operator 12 can observe the fabric web in the area of the fixed deflecting roller 24 or the free path 25 from the closed operating station 13 without problems and also check the correct needling of the fabric web 2 on the needles 27b and intervene to correct it, if necessary. Even when the sections are open, the operator has free access to all of the rollers in the area of the tissue insertion 11 from the crosspiece 32.

Zum Einführen der Gewebebahn 2 in die Einwirkzone 5 ist es erforderlich, die einzelnen Walzen voneinanderzu trennen, damit die Gewebebahn 2 ohne grossen Aufwand durchgezogen werden kann. Eine Ablösung der Walzen hat auch bei längerem Maschinenstillstand zu erfolgen, um die Weichgummiüberzüge der Walzen zu schonen.To insert the fabric web 2 into the action zone 5, it is necessary to separate the individual rollers from one another so that the fabric web 2 can be pulled through without great effort. The rollers must also be detached when the machine is at a standstill for a long time in order to protect the soft rubber coatings on the rollers.

Figur 3 zeigt die Walzenanordnung im entlasteten Zustand. Die Quetschwalze 16 ist von der Antriebswalze 15 abgehoben. Dies erfolgt über einen hier nicht näher dargestellten Quetschzylinder. Die Aufliegewalze 20 ist mit Hilfe des Exzenters 29 von Hand oder automatisch von der ersten Fixwalze 21a abgehoben. Dabei fällt die Gewebezugreglerwalze 17 gegen einen Anschlag 30a im Schwenkbereich ihrer Achse. Die Pneumatikzylinder 23a bis 23d sind entlastet bzw. zurückgezogen, so dass die ihnen zugeordneten Zustellwalzen 22a bis 22d gegen ihre zugehörigen Anschläge fallen. Es wäre selbstverständlich denkbar, dass die Pneumatikzylinder 23a bis 23d gemeinsam mit dem Exzenter 29 aktivierbar sind. In jedem Fall ist es vorteilhaft, die Pneumatikzylinder über eine Steuervorrichtung gemeinsam anzusteuern, so dass eine gleichzeitige Abhebung der Walzen erfolgt. Die Anordnung der Walzen ist ausserdem so gewählt, dass auch bei eingezogener Gewebebahn 2 ein Abheben der Walzen ohne Streckung der Gewebebahn möglich ist.Figure 3 shows the roller assembly in the unloaded state. The squeeze roller 16 is lifted off the drive roller 15. This is done via a squeeze cylinder, not shown here. The lay-on roller 20 is lifted by hand or automatically from the first fixed roller 21a with the aid of the eccentric 29. The fabric tension regulator roller 17 falls against a stop 30a in the swivel range of its axis. The pneumatic cylinders 23a to 23d are relieved or withdrawn, so that the feed rollers 22a to 22d assigned to them fall against their associated stops. It would of course be conceivable that the pneumatic cylinders 23a to 23d can be activated together with the eccentric 29. In any case, it is advantageous to control the pneumatic cylinders together via a control device, so that the rollers are lifted off at the same time. The arrangement of the rollers is also selected so that the rollers can be lifted without stretching the fabric web even when the fabric web 2 is drawn in.

Selbstverständlich ist die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt. So wäre es insbesondere denkbar, zur Umfahrung des Bedienungsstandes zusätzliche Fixwalzen und Zustellwalzen zu verwenden. Denkbar wäre auch die Anordnung einer zusätzlichen Gewebezugreglerwalze am Ende der Einwirkzone 5, oder der Einbau einer zusätzlichen Quetsche.Of course, the invention is not limited to the illustrated embodiment. It would be conceivable, in particular, to use additional fixed rollers and feed rollers to bypass the operating station. It would also be conceivable to arrange an additional fabric tension regulator roller at the end of the zone of action 5 or to install an additional squeeze.
