Description
Die Erfindung bezieht sich auf eine Vorrichtung zum gleichmäßigen Auftragen einer minimalen Menge eines Behandlungs- wie Veredelungsfluids auf eine vorbeilaufende, eine gewisse Breite aufweisende textile Warenbahn mit einem quer zur Warenbahn ausgerichteten Auftragsbalken, welcher einen sich über die Breite der Warenbahn erstreckenden, gegen die Warenbahn gerichteten offenen Schlitz aufweist, dem das Fluid gleichmäßig über die Arbeitsbreite der Warenbahn zugeführt ist, und mit einer dem Schlitz auf der anderen Seite der Warenbahn gegenüberliegenden, parallel zum Auftragsbalken ausgerichteten Walze als Abstützung für die Warenbahn.The invention relates to a device for uniform application minimal amount of a treatment fluid such as a finishing fluid on a passing, a certain width of textile web with a cross to the web aligned order bar, which is one across the width of the web extending, directed against the web open slot, which the Fluid is fed evenly across the working width of the web, and with a opposite the slot on the other side of the web, parallel to the Order bar aligned roller as support for the web.
Eine Vorrichtung dieser Art ist durch die DE-A-23 21 912 bekannt. Dort geht es um eine Beschichtungsvorrichtung, mit der also die Warenbahn mit einer gleichmäßig dicken Beschichtungschicht versehen werden soll. Dazu weist der Schlitz, durch den die Beschichtungsflüssigkeit zufließt, zwei Längskanten auf, von denen die erste (in Richtung der vorlaufenden Warenbahn gesehen) höher ausgebildet ist als die zweite, die zur Bildung der Beschichtungsdicke mit Abstand zur ablaufenden Warenbahn ausgebildet ist. Mit Vorzug ist sogar die zweite, die ablaufende Kante des Schlitzes über eine Länge gleichbleibend mit Abstand zur Warenbahn angeordnet zur Beeinflussung einer gleichbleibenden, glatten Beschichtungsdicke. Den Ausgleich der Beschichtungsdicke beeinflußt auch eine auf der anderen Seite der Warenbahn dem Schlitz zugeordnete, ggf. angetriebene Preßwalze, die gegen die erste Längskante des Schlitzes gedrückt ist. um insofern eine Überhöhung der ansonsten notwendigen Längsspannung der Warenbahn zu vermeiden.A device of this type is known from DE-A-23 21 912. It's about there a coating device, with which the material web with a uniform thick coating layer should be provided. To do this, the slot through which the coating liquid flows in, two longitudinal edges, of which the first (in Seen direction of the leading web) is higher than the second, to form the coating thickness at a distance from the running web is trained. Even the second, the draining edge of the slot, is preferred over a length arranged at a distance from the web Influencing a constant, smooth coating thickness. Balancing the Coating thickness also affects that on the other side of the web Slit associated, possibly driven press roll, against the first longitudinal edge of the slot is pressed. in order to exaggerate the otherwise necessary Avoid longitudinal tension of the web.
Neben dieser Art von Beschichtungsvorrichtungen sind außer den Aufgießvorrichtungen nur noch die Siebdruckvorrichtungen bekannt, bei denen die Abstützung aus einem horizontalen Sieb- ggf. mit Absaugung oder einem dichten Endlosband, aber auch aus einer Walze bestehen kann, die die Warenbahn am Schlitz vorbei trägt. Hier ist beispielsweise die EP-A-0 108 887 oder die DE-A-34 19 367 zu nennen. Wesentlich bei Siebdruckmaschinen ist aber, daß der Schlitz von einem sich drehenden Siebzylinder umgeben ist, durch dessen Perforation die Flüssigkeit zur Herstellung eines Musters gedrückt werden soll. Nach der EP-A-0 108 887 ist dieser als Schablone dienende Siebzylinder auch entfernbar, so daß die die Warenbahn unterstützende Walze direkt mit ihr Kontakt hat. Jedenfalls soll mit solchen Vorrichtungen eine Flüssigkeit, eine Flüssigkeitsschicht lediglich aufgetragen, die Warenbahn also z. B. bedruckt werden. Um solche Vorrichtungen geht es beim Anmeldungsgegenstand nicht, vielmehr soll eine Vorrichtung gefunden werden, mit der die Warenbahnoberfläche mit nur einer Minimalmenge der Flüssigkeit gleichmäßig über die Arbeitsbreite getränkt und gleichzeitig optimal in die Oberfläche wie Flor eingedrückt werden kann, um eben gerade nur die Warenbahnoberfläche, z. B. den Flor vollständig zu tränken.In addition to this type of coating devices are Aufgießvorrichtungen known only the screen printing devices in which the Support from a horizontal sieve - if necessary with suction or a tight one Endless belt, but can also consist of a roller that slits the web of material carries over. For example, EP-A-0 108 887 or DE-A-34 19 367 apply here call. It is essential in screen printing machines, however, that the slot is one rotating screen cylinder is surrounded, through the perforation of the liquid Making a pattern to be pressed. According to EP-A-0 108 887 this is serving as a template screen cylinder also removable, so that the web supporting roller has direct contact with it. In any case, with such Devices just applied a liquid, a layer of liquid that Goods web so z. B. are printed. Such devices are concerned with Subject of the application is not, rather a device is to be found with which the web surface evenly with only a minimal amount of liquid soaked across the working width and at the same time optimally into the surface like pile can be pressed to just just the web surface, z. B. the Soak pile completely.
Ausgehend von der Vorrichtung anfangs genannter Art besteht die Aufgabe der Erfindung darin, eine Vorrichtung zu finden, mit der die zur ausreichenden Netzung minimal notwendige Flüssigkeitsmenge nicht nur gleichmäßig über die Arbeitsbreite verteilt, sondern auch gleichzeitig in die Faseroberfläche der Warenbahn wie in den Flor od. dgl. penetriert wird.The object of the invention is based on the device initially mentioned in finding a device with which to achieve sufficient wetting minimal not only the necessary amount of liquid evenly distributed over the working width, but also simultaneously in the fiber surface of the web as in the pile od. Like. is penetrated.
Zur Lösung der gestellten Aufgabe sieht die Erfindung vor, daß der Vorrichtung eine mit einer Faseroberfläche versehene Warenbahn wie Florware zugeführt ist, die Walze gegen die beiden den Schlitz des Auftragsbalkens begrenzenden Längskanten des Schlitzes gedrückt wird, womit durch den Druck der Preßwalze die dazwischen vorlaufende Warenbahn sowohl an der einlaufenden Längskante als auch an der auslaufenden Längskante des Schlitzes komprimiert ist, und die Längskanten des Schlitzes mit einem Abstand voneinander angeordnet sind, daß die zu netzende, an der einlaufenden Längskante durch den Druck der Preßwalze entlüftete faserige Oberfläche der Warenbahn in dem zwischen den Längskanten vorhandenen Schlitz entlastet vom Druck der Preßwalze aufatmet, dabei die durch den Schlitz zugeführte Flüssigkeit aufsaugt, um gleich anschließend an der auslaufenden Längskante wieder durch den Druck der Preßwalze zur Flüssigkeitsreduzierung gepreßt zu werden.. Diese drei Vorgänge: Komprimierung, Aufatmung und wieder Komprimierung des Flors sind bei der Vorrichtung nach der Erfindung während des Auftrags unmittelbar hintereinander geschaltet, so daß der gewünschte sparsame Fluidminimalauftrag im Zusammenhang mit einem auch geringen Flüssigkeitsverbrauch gewährleistet ist.To achieve the object, the invention provides that the device web provided with a fiber surface, such as pile goods, is fed to the roller against the two longitudinal edges of the Slot is pressed, with the pressure of the press roller between them leading material web both on the incoming longitudinal edge and on the leading longitudinal edge of the slot is compressed, and the longitudinal edges of the Slot are arranged at a distance from each other that the to be wetted the incoming longitudinal edge is deflated by the pressure of the press roll Surface of the web in the slot between the longitudinal edges Relieved from the pressure of the press roller, breathing through the slot Soaks up liquid, then immediately afterwards at the longitudinal edge to be pressed by the pressure of the press roller to reduce liquid .. This three processes: compressing, breathing deeply and again compressing the pile in the device according to the invention during the order immediately connected in series so that the desired economical fluid minimum order in Connection with a low fluid consumption is guaranteed.
Der Abstand der Längskanten des Schlitzes hängt von der Art und dem Volumen der zu behandelnden Ware ab. Jedenfalls soll die an der Preßwalze zusammengedrückte Oberfläche der Warenbahn sich wieder aufrichten, aufatmen, dabei die Flüssigkeit aufsaugen können und dann wieder zusammengequetscht werden, damit nur die wirklich notwendige Flüssigkeitsmenge im Flor verbleibt. Es ist daran gedacht, den Abstand der Längskanten des Schlitzes in der Größenordnung der doppelten Länge des jeweiligen Flors der Warenbahn zu bemessen. Der Schlitz kann aber auch breiter sein.The distance between the longitudinal edges of the slot depends on the type and volume of the goods to be treated. In any case, the one that is pressed together on the press roll The surface of the web straighten up again, take a deep breath, taking the liquid can soak up and then squeezed together, so that only really necessary amount of liquid remains in the pile. It is thought of the distance the longitudinal edges of the slot in the order of twice the length of the to dimension each pile of the web. The slot can also be wider.
Wesentlich ist auch die gleichmäßige Zuführung des Behandlungsfluids in und über die Breite des Schlitzes. Für diese Aufgabe gibt es eine gute Lösung nach der DE-A-40 26 198. Deshalb wird auch bei der Vorrichtung nach der Erfindung vorgeschlagen, daß der Schlitz mit einer Flüssigkeitsverteileinrichtung verbunden ist, bei der die Verteilung der Flüssigkeit von einer Zuflußleitung bis zu einer Vielzahl von Ausflußöffnungen schrittweise derart vorgesehen ist, daß die Zuflußöffnung beidseitig in Arbeitsbreitenrichtung mit einer gleich langen ersten Verzweigleitung verbunden ist, an deren jeweiligem Ende eine Zwischenausflußöffnung vorgesehen ist, an die sich in gleicher Weise beidseitig in Arbeitsbreitenrichtung eine jedoch um die Hälfte der ersten Verzweigleitung kürzere und im Querschnitt verkleinerte zweite Verzweigleitung anschließt, sich die Flüssigkeitsverteilung in dieser Flüssigkeitsverteileinrichtung also stammbaumähnlich mehrfach verzweigt, und daß somit die fein über die Arbeitsbreite verteilten Ausflußöffnungen in den sich über die Arbeitsbreite der Warenbahn erstreckenden Schlitz münden.It is also essential that the treatment fluid is fed in and over uniformly the width of the slot. There is a good solution for this task according to DE-A-40 26 198. Therefore, it is also proposed in the device according to the invention that that the slot is connected to a liquid distribution device in which the distribution the liquid from an inflow line to a plurality of outflow openings is gradually provided such that the inflow opening on both sides in the working width direction is connected to an equally long first branch line, at the each end, an intermediate outflow opening is provided, to which the same However, on both sides in the working width direction by half of the first branch line connects a shorter branch line with a smaller cross section, the liquid distribution in this liquid distribution device Similar to family tree, branched several times, and thus that finely over the working width distributed outflow openings in the extending over the working width of the web Slot.

Schlitz hat an der Auftrittsseite zwei Längskanten 19, 20, die sich über die Arbeitsbreite
des Auftragsbalkens 14 erstrecken. Die Höhe des Schlitzes 18 ergibt sich gemäß
Ausführungsbeispiel aus der im Querschnitt halbkreisförmigen Gestaltung. Die
auf der anderen Seite der Warenbahn 2 zentrisch zum Schlitz 18 angeordnete
Preßwalze 16 liegt - über die Warenbahn 2 - an den Längskanten 19, 20 des Schlitzes
18 an. Auf diese Weise wird der Flor 2' der Warenbahn 2 beim Durchlauf durch die
Auftragsvorrichtung 13 zunächst an der Längskante 19 komprimiert, entlüftet, dann im
Schlitz 18 nach dem oder beim Aufrichten mit der jeweiligen Auftragsflüssigkeit genetzt
und dann wieder an der Längskante 20 komprimiert, damit nur die minimal erforderliche
Flüssigkeit in dem Flor 2' verbleibt.The order bar 14 has a slot on the side assigned to the
Damit die auf die Warenbahn 2 aufzutragende Flüssigkeit gleichmäßig über die Arbeitsbreite
im Schlitz 18 verteilt geliefert wird, ist im Auftragsbalken 14 eine Verteilvorrichtung
15 vorgesehen, die aus Fig. 3 hervorgeht. Die Verteilung der Flüssigkeit erfolgt
