Description

"Luftkasten einer Ausrüstungsmaschine"  "Airbox of an Equipment Machine"
Beschreibung: Description:
Die Erfindung betrifft einen Luftkasten einer Ausrüstungsmaschi- ne. The invention relates to an air box of an equipment machine.
Ausrüstungsmaschinen dienen dazu, einer Textilbahn mit Hilfe einer so genannten Thermofixierung die gewünschte Formstabilität zu verleihen. Beispielsweise kann zunächst auf einer Web- maschine eine Gewebebahn aus Kunststofffäden erzeugt worden sein, wobei diese Gewebebahn nach dem Verweben noch nicht formstabil ist. Für bestimmte Anwendungen der Gewebebahn kann die unvollständige Formstabilität nachteilig sein, beispielsweise wenn die Gewebebahn zu einer geschlossenen End- losbahn vernäht wird und in einer Produktionsmaschine, beispielsweise im Bereich der Papierherstellung, als umlaufendes Band eingesetzt werden soll. Abmessungsänderungen in Längsoder Querrichtung innerhalb der Produktionsmaschine können zu Betriebsstörungen führen. Equipment machines serve to give a textile web the desired dimensional stability by means of a so-called heat setting. For example, first a fabric web of plastic threads may have been produced on a weaving machine, wherein this fabric web is not yet dimensionally stable after weaving. For certain applications of the fabric web, the incomplete dimensional stability may be disadvantageous, for example if the fabric web is sewn into a closed final web and is to be used as a circulating belt in a production machine, for example in the field of papermaking. Dimensional changes in the longitudinal or transverse direction within the production machine can lead to malfunctions.
Die Ausrüstungsmaschine dient dazu, mit Hilfe von Wärmeeinwirkung das Textilmaterial zu fixieren. Zudem kann in der Ausrüstungsmaschine eine Dehnung der Textilbahn vorgesehen sein, indem die Textilbahn beispielsweise um zwei Umlenkrollen geführt wird und deren Abstand nach und nach vergrößert wird. Die Wärmebehandlung der Textilbahn weist zwei wesentliche Aspekte auf: Bei optimaler Konstellation der Wärmeeinbringung in die Textilbahn kann ein Aufheizprozess des Kunststoffmateri- als auf etwa 180° bereits nach etwa 3 s abgeschlossen sein, abhängig von den jeweils für die Textilbahn verwendeten Materialien. Eine anschließende so genannte Kristallisation des textilen Kunststoffmaterials benötigt allerdings eine Zeit von etwa 3 min. Da die Kristallisation nicht am Stück zu erfolgen braucht, sondern vielmehr in mehreren Stufen durchlaufen werden kann, erfolgt in der Praxis die Wärmebehandlung in der Ausrüstungsmaschine derart, dass die Textilbahn zu einer geschlossenen Schlaufe vernäht wird, um die beiden im Abstand veränderlichen Umlenkrollen geführt wird und dabei mehrere Umläufe macht, so dass sämtliche Bereiche der Textilbahn mehrfach durch den Luftkasten der Ausrüstungsmaschine geführt werden, wo die Textilbahn aufgeheizt wird. The equipment machine serves to fix the textile material with the help of heat. In addition, an elongation of the textile web can be provided in the finishing machine, for example, by the textile web is guided around two pulleys and their distance is gradually increased. The heat treatment of the textile web has two essential aspects: With optimal constellation of heat input into the textile web, a heating process of the plastic material can be completed at about 180 ° already after about 3 s, depending on the materials used for the textile web. However, a subsequent so-called crystallization of the textile plastic material requires a time of about 3 min. Since the crystallization does not need to be done in one piece, but rather can be run through in several stages, in practice, the heat treatment in the finishing machine such that the textile web is sewn into a closed loop, is guided around the two variable deflection pulleys and doing several revolutions, so that all areas of the textile web are repeatedly passed through the air box of the finishing machine, where the textile web is heated.
Dabei hat es sich in der Praxis bewährt, statt einer Strahlungsbeheizung die Heizwirkung mit Hilfe von Heißluft vorzunehmen, so dass bei einem gattungsgemäßen Luftkasten Luftaustrittsdüsen vorgesehen sind, aus denen die Heißluft auf die Textilbahn strömt. Weiterhin sind Luftansaugöffnungen vorgesehen, welche die Luft ansaugen, so dass die Heißluft vorzugsweise nur zu einem möglichst geringen Anteil unkontrolliert aus dem Gehäuse des Luftkastens herausströmt und stattdessen vielmehr im Kreislauf geführt werden kann, um mit einem möglichst geringen Heizleistungsbedarf die Ausrüstungsmaschine betreiben zu können. It has been proven in practice, instead of radiant heating to make the heating effect using hot air, so that in a generic air box air outlet nozzles are provided, from which the hot air flows onto the textile web. Furthermore, air intake openings are provided which suck in the air, so that the hot air preferably flows out of the housing of the air box only to the smallest possible extent in an uncontrolled manner and instead can instead be recirculated in order to be able to operate the equipment machine with the lowest possible heating power requirement.
Aus der DE 37 41 876 A1 ist eine Vorrichtung zur Wärmebehandlung einer breitgeführten textilen Warenbahn bekannt, die eine Temperatur-Haltezone an einem Trockner aufweist. From DE 37 41 876 A1 discloses a device for heat treatment of a wide-web textile web is known, which has a temperature-holding zone on a dryer.
Ein gattungsgemäßer Luftkasten ist beispielsweise von der Firma Alfsen og Gunderson AS, Oslo, Norwegen unter der Bezeichnung "AG Air Through Compact" und aus deren Veröffentli- chung im Internet mit der URL: http://www.ag.no/products-and- services/felts-and-fabrics/heatsetting-systems/air-through- compact.aspx bekannt. Dabei sind im oberen Gehäuseabschnitt abwechselnd Luftaustrittsdüsen und Luftansaugöffnungen angeordnet und im darunter befindlichen unteren Gehäuseabschnitt sind komplementär dazu Luftansaugöffnungen unterhalb der oberen Luftaustrittsdüsen angeordnet und in umgekehrter Weise Luftaustrittsdüsen im unteren Gehäuseabschnitt dort vorgesehen, wo sich darüber im oberen Gehäuseabschnitt Luftansaugöffnungen befinden. So wird der gesamte Innenraum des Luftkasten-Gehäuses zum Aufheizen der Textilbahn genutzt, welche durch das Gehäuse geführt wird, indem praktisch die gesamte Länge der Textilbahn, die sich innerhalb des Gehäuses befindet, von Heißluft durchströmt werden soll. A generic air box is for example from the company Alfsen og Gunderson AS, Oslo, Norway under the name "AG Air Through Compact" and from their publication on the Internet using the URL: http://www.ag.no/products-and-services/felt-and-foils/heatsetting-systems/air-through-compact.aspx. Air outlet nozzles and air intake openings are alternately arranged in the upper housing section, and air intake openings are arranged below the upper air outlet nozzles in the lower housing section in a complementary manner and air outlet nozzles are provided in the lower housing section in the reverse direction where air intake openings are located in the upper housing section. Thus, the entire interior of the air box housing is used for heating the textile web, which is guided through the housing by virtually the entire length of the textile web, which is located within the housing, to be flowed through by hot air.
Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Luftkasten dahingehend zu verbessern, dass die Wärmebehandlung einer Textilbahn in einer möglichst kurzen Zeit fertig gestellt werden kann und möglichst wenig Umläufe der Textilbahn durch die Ausrüstungsmaschine erfordert. The invention has for its object to improve a generic air box to the effect that the heat treatment of a textile web can be completed in the shortest possible time and requires as few revolutions of the textile web through the equipment machine.
Diese Aufgabe wird durch einen Luftkasten mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben. This object is achieved by an air box with the features of claim 1. Advantageous embodiments are described in the subclaims.
Die Erfindung schlägt mit anderen Worten vor, nicht den gesamten Innenraum des Luftkastens zum Aufheizen der Textilbahn zu verwenden, sondern vielmehr innerhalb des Gehäuses zunächst eine Aufheizzone vorzusehen und dann, der Aufheizzone in Laufrichtung der Textilbahn nachgeschaltet, eine Temperatur- Haltezone vorzusehen, in welcher die Kristallisation des Textil- bandes erfolgen kann. In other words, the invention proposes not to use the entire interior of the air box for heating the textile web, but rather to initially provide a heating zone inside the housing and then, downstream of the heating zone in the direction of the textile web, to provide a temperature holding zone in which the Crystallization of the textile tape can be done.
Die Erfindung geht dabei von der Überlegung aus, dass sich die Textilbahn, wenn sie den Luftkasten verlässt, schnell an der Umgebungsluft abkühlt, so dass für die Kristallisation nur ein vergleichsweise kurzer Zeitraum zur Verfügung steht, in welchem die aufgeheizte Textilbahn noch ein ausreichend hohes Temperaturniveau aufweist, um eine Kristallisation zu ermöglichen. Dadurch, dass vorschlagsgemäß innerhalb des Luftkastens eine Temperatur-Haltezone vorgesehen ist, wird die Textilbahn für eine demgegenüber längere Zeitdauer in einem Kristallisations-Temperaturbereich gehalten, so dass dementsprechend die Kristallisation schneller abgeschlossen werden kann, d. h. mit weniger Umläufen als bisher, und somit die Leistungsfähigkeit der Ausrüstungsmaschine verbessert wird, weil innerhalb einer vorgegebenen Zeit eine größere Anzahl von Textilbändern behandelt werden kann. The invention is based on the consideration that the textile web, when it leaves the air box, cools quickly to the ambient air, so that only one for the crystallization comparatively short period is available in which the heated textile web still has a sufficiently high temperature level to allow crystallization. By virtue of the proposal that a temperature-holding zone be provided within the air box, the textile web is kept in a crystallization temperature range for a relatively long period of time, so that accordingly crystallization can be completed more quickly, ie with fewer turns than before, and thus the efficiency the finishing machine is improved because within a given time a larger number of textile ribbons can be treated.
Der Luftkasten erstreckt sich üblicherweise in den Verstellweg der verstellbaren Umlenkrolle hinein, so dass durch die Länge, die der Luftkasten in Bahnlaufrichtung aufweist, der Mindestabstand der beiden Umlenkrollen bestimmt wird. Die Erfindung geht weiterhin von der Überlegung aus, dass die Aufheizung der Textilbahn auf das gewünschte Temperaturniveau auch in einer kürzeren Aufheizzone möglich ist als sie bislang üblich ist, so dass innerhalb des Gehäuses die Aufheizzone auf einen Teil der Gehäuselänge in Bahnlaufrichtung begrenzt werden kann und daher der Rest der Gehäuselänge als Temperatur-Haltezone verfügbar ist. Daher kann vorteilhaft vorgesehen sein, dass die Länge des Luftkastens in Bahnlaufrichtung nicht größer bemessen sein muss als bei herkömmlichen praxisüblichen Luftkästen. Durch die Beibehaltung einer möglichst kurzen Baulänge kann der Abstand zwischen den beiden Umlenkrollen der Ausrüstungsmaschine möglichst klein gehalten werden, so dass auch kürzere Textilbahnen in der Ausrüstungsmaschine verarbeitet werden können. The air box usually extends into the adjustment path of the adjustable deflection roller, so that the minimum distance of the two deflection rollers is determined by the length which the air box has in the web running direction. The invention is further based on the consideration that the heating of the textile web to the desired temperature level is possible even in a shorter heating zone than has hitherto been customary, so that within the housing, the heating zone can be limited to a part of the housing length in the web running direction and therefore the remainder of the housing length is available as a temperature holding zone. Therefore, it can be advantageously provided that the length of the air box in the web running direction must not be greater than in conventional practice air boxes. By maintaining the shortest possible length of the distance between the two pulleys of the finishing machine can be kept as small as possible, so that even shorter textile webs can be processed in the finishing machine.
Vorteilhaft kann vorgesehen sein, dass kurz bevor die Textilbahn aus dem Gehäuse wieder austritt, eine Luftansaugöffnung innerhalb des Gehäuses angeordnet ist, also innerhalb der Temperatur-Haltezone. Während die Luftaustrittsdüsen in der Tempera- tur-Aufheizzone vorgesehen sind, so dass dort die intensive Aufheizung der Textilbahn erfolgen kann, bewirkt die weit hinten angeordnete zusätzliche Luftansaugöffnung, dass ein Teil der Heißluft zusammen mit der Textilbahn durch das Gehäuse ge- führt wird, so das der Effekt unterstützt wird, die Textilbahn auf einem für die Kristallisation erforderlichen Temperaturniveau zu halten, während sie sich in der Temperatur-Haltezone innerhalb des Gehäuses befindet. Vorteilhaft kann vorgesehen sein, dass die Düsenöffnungen derAdvantageously, it can be provided that just before the textile web exits the housing again, an air intake opening is arranged within the housing, ie within the temperature-holding zone. While the air outlet nozzles in the tempera- are provided so that there can be intensive heating of the textile web, causes the far back arranged additional air intake that part of the hot air is led together with the textile web through the housing, so that the effect is supported, the Textile web to maintain a temperature level required for the crystallization, while it is in the temperature-holding zone within the housing. It can advantageously be provided that the nozzle openings of the
Luftaustrittsdüsen und auch der Luftansaugöffnungen jeweils quer zur Fläche der Textilbahn ausgerichtet sind. Hierdurch wird eine Luftströmung begünstigt, bei welcher die Durchluftströmung quer zur Fläche der Textilbahn strömt und beispielsweise senk- recht auf die Textilbahn trifft. Beim Auftreffen der Luft auf dieAir outlet nozzles and the air intake openings are each aligned transversely to the surface of the textile web. This promotes an air flow in which the throughflow of air flows transversely to the surface of the textile web and, for example, hits the textile web vertically. Upon impact of the air on the
Textilbahn wird stets ein gewisser Anteil der Luft reflektiert und lediglich ein übriger Anteil der Luft tritt durch die Textilbahn hindurch. Die jeweiligen Anteile hängen u. a. von der jeweiligen Ausgestaltung der Textilbahn ab, z. B. von deren Materialstärke und von der Ausgestaltung der Poren in der Textilbahn. Ein weiterer Einflussfaktor ist jedoch auch der Winkel, unter welchem die Luft auf die Textilbahn auftrifft. Dementsprechend kann vorteilhaft vorgesehen sein, dass die Düsenöffnungen der Luftaustritte zur Fläche der Textilbahn ausgerichtet sind, so dass die ausströmende Heißluft quer, beispielsweise senkrecht, auf dieTextile web is always reflected a certain proportion of the air and only a remaining portion of the air passes through the textile web. The respective proportions depend u. a. from the particular embodiment of the textile web, z. B. of the material thickness and the design of the pores in the textile web. However, another influencing factor is the angle at which the air impinges on the textile web. Accordingly, it can be advantageously provided that the nozzle openings of the air outlets are aligned with the surface of the textile web, so that the outflowing hot air transversely, for example vertically, on the
Fläche der Textilbahn auftrifft und somit ein möglichst großer Anteil der Heißluft als Durchluftströmung durch die Textilbahn hindurchtreten und daher die Textilbahn möglichst intensiv aufheizen kann. Surface of the textile web impinges and thus the largest possible portion of the hot air pass through the textile web as through air flow and therefore can heat the textile web as intense as possible.
Um die Durchluftströmung möglichst senkrecht zur Fläche der Textilbahn auszugestalten, kann dementsprechend auch vorteilhaft vorgesehen sein, dass die Düsenöffnungen der Luftansaugöffnungen unmittelbar den Luftaustrittsöffnungen gegenüber liegen, so dass sie einen Luftstrom ansaugen, der möglichst senkrecht zur Fläche der Textilbahn verläuft. Durch die geschil- derten Ausrichtungen der Düsenöffnungen sowohl bei den Luftaustrittsdüsen und vorteilhaft auch bei den Luftansaugöffnungen kann die Heizwirkung optimiert werden, so dass das Tempera- turniveau der Textilbahn möglichst schnell erreicht werden kann und dementsprechend ein möglichst kleiner erster Bereich innerhalb des Gehäuses des Luftkastens für die Temperatur- Aufheizzone bereitgestellt werden muss, so dass dementsprechend ein größerer Anteil des Gehäuses für die Temperatur- Haltezone genutzt werden kann und dementsprechend eine längere Zeit zur Kristallisation der Textilbahn zur Verfügung steht. Im Vergleich zu den intensiven Luftströmungen, die innerhalb der Aufheizzone des Gehäuses vorgesehen sind, ist in der Temperatur-Haltezone keine intensive Durchströmung der Textilbahn vorgesehen, sondern hier soll nur das Temperaturniveau gehalten werden, welches die Kristallisation des Kunststoffmaterials ermöglicht. Dementsprechend kann vorteilhaft vorgesehen sein, dass in der Temperatur-Haltezone entweder der obere oder der untere Gehäuseabschnitt zur Textilbahn hin geschlossen ist, so dass ein strömungsberuhigter Bereich innerhalb des jeweiligen Gehäuseabschnitts geschaffen wird, der durch die sich bewegende Textilbahn nicht beeinträchtigt wird, beispielsweise nicht durch Verwirbelungen den gewünschten Verlauf der Luftströmungen beeinträchtigt. In order to design the through-air flow as perpendicular as possible to the surface of the textile web, it can accordingly also be advantageously provided that the nozzle openings of the air intake openings are directly opposite the air outlet openings, so that they suck in an air flow which is as perpendicular as possible to the surface of the textile web. Through the As well as the air outlet nozzles and advantageously also in the air intake openings the heating effect can be optimized, so that the temperature level of the textile web can be reached as quickly as possible and accordingly a smallest possible first area within the housing of the air box for the temperature heating zone must be provided, so that accordingly a larger proportion of the housing for the temperature-holding zone can be used and accordingly a longer time is available for the crystallization of the textile web. Compared to the intense air currents that are provided within the heating zone of the housing, no intensive flow through the textile web is provided in the temperature-holding zone, but here only the temperature level is to be maintained, which allows the crystallization of the plastic material. Accordingly, it may be advantageously provided that in the temperature-holding zone, either the upper or the lower housing portion is closed to the textile web, so that a flow-calmed area is created within the respective housing portion, which is not affected by the moving textile web, for example not through Turbulence affected the desired course of the air currents.
Besonders vorteilhaft kann vorgesehen sein, sowohl den oberen als auch den unteren Gehäuseabschnitt zur Textilbahn hin abzuschließen, so dass ein flacher so genannter Bahntunnel geschaffen wird, durch welchen die Textilbahn innerhalb des Gehäuses nämlich in der Temperatur-Haltezone verläuft. Durch diesen flachen Bahntunnel kann unterstützt werden, dass die Textilbahn in einem bestimmten Temperaturbereich gehalten werden kann, indem nämlich Luft mit der entsprechenden Temperatur sich in dem Bahntunnel befindet und diese Luft wird durch die Begrenzungsflächen des Bahntunnels vor Auskühlung geschützt und zuverlässig nahe der Textilbahn gehalten. Ein Ausführungsbeispiel eines vorschlagsgemäßen Luftkastens wird anhand der rein schematischen Darstellung nachfolgend näher erläutert. Particularly advantageous may be provided to complete both the upper and the lower housing portion towards the textile web, so that a flat so-called railway tunnel is created through which the textile web runs within the housing namely in the temperature-holding zone. By means of this flat railway tunnel it can be supported that the textile web can be kept in a certain temperature range, namely by having air at the appropriate temperature in the railway tunnel and this air is protected against cooling down by the boundary surfaces of the railway tunnel and reliably held close to the textile web. An embodiment of a proposed air box is explained in more detail below with reference to the purely schematic representation.
In der Zeichnung ist mit 1 insgesamt ein Luftkasten bezeichnet, der Teil einer Ausrüstungsmaschine ist, wobei rechts und links von dem dargestellten Luftkasten 1 Umlenkrollen vorgesehen sind, um welche eine Textilbahn 2 umläuft, beispielsweise eine Gewebebahn eines Kunststoffgewebes, welches, von einer Webmaschine kommend, zu einer geschlossenen Schlaufe zusammengenäht worden ist. Die Laufrichtung der Textilbahn 2 ist durch den Pfeil angedeutet, verläuft also von links nach rechts durch den Luftkasten 1 , wobei dies das Obertrum der Textilbahn 2 betrifft, während das Untertrum dementsprechend unterhalb des Luftkastens 1 von rechts nach links zurückläuft. In the drawing, 1 designates a total of an air box, which is part of an equipment machine, to the right and left of the illustrated air box 1 deflection rollers are provided, which surrounds a textile web 2, for example, a fabric web of a plastic fabric, which, coming from a loom, sewn together into a closed loop. The running direction of the textile web 2 is indicated by the arrow, thus extending from left to right through the air box 1, wherein this concerns the upper run of the textile web 2, while the lower run correspondingly runs back below the air box 1 from right to left.
Der Luftkasten 1 weist einen oberen Gehäuseabschnitt 3 auf, der oberhalb der Textilbahn 2 angeordnet ist, sowie einen unteren Gehäuseabschnitt 4, der unterhalb der Textilbahn 2 angeordnet ist. The air box 1 has an upper housing section 3, which is arranged above the textile web 2, and a lower housing section 4, which is arranged below the textile web 2.
Im oberen Gehäuseabschnitt 3 ist ein Druckluftkanal 5 vorgesehen, der zwei Luftaustrittsdüsen 6 aufweist, die senkrecht auf die Fläche der Textilbahn 2 gerichtet sind. Dem Druckluftkanal 5 gegenüberliegend ist im unteren Gehäuseabschnitt 4 ein Saugkanal 7 angeordnet, dessen Luftansaugöffnung 8 ebenfalls senkrecht zur Fläche der Textilbahn ausgerichtet ist. In the upper housing section 3, a compressed air channel 5 is provided, which has two air outlet nozzles 6, which are directed perpendicular to the surface of the textile web 2. The compressed air channel 5 opposite a suction channel 7 is arranged in the lower housing portion 4, the air intake opening 8 is also aligned perpendicular to the surface of the textile web.
Durch die gegenüberliegende Anordnung des Druckluftkanals 5 und des Saugkanals 7 wird eine möglichst senkrecht durch die Textilbahn 2 strömende Durchluftströmung begünstigt. Da jedoch ein Teil der Heißluft, die aus den Luftaustrittsdüsen 6 auf die Textilbahn 2 auftritt, reflektiert wird, sind im oberen Gehäuseabschnitt 3 beiderseits des Druckluftkanals 5 also in Laufrichtung der Textilbahn 2 vor und hinter dem Druckluftkanal 5, weitere Saugkanäle 7 angeordnet. Der links dargestellte Saugkanal 7 ist vergleichsweise klein bemessen, da er ausschließlich die reflektierte Luft aufnehmen muss. Der in Bahnlaufrichtung folgende, also rechts dargestellte Saugkanal 7 im oberen Gehäuseabschnitt 3, ist demgegenüber größer dargestellt. Dies soll verdeut- liehen, dass durch diesen Saugkanal 7 eine größere Luftmenge angesaugt wird, nämlich nicht nur Heißluft, die vom oberen Druckluftkanal 5 reflektiert wird, sondern auch Heißluft, die aus einem unteren Druckluftkanal 5 strömt, der im unteren Gehäuseabschnitt 4 angeordnet ist und dessen Luftaustrittsdüsen 6 un- terhalb des rechten oberen Saugkanals 7 angeordnet sind. Due to the opposing arrangement of the compressed air channel 5 and the suction channel 7 a possible vertical through the textile web 2 flowing through air flow is favored. However, since a part of the hot air, which occurs from the air outlet nozzles 6 on the textile web 2, is reflected in the upper housing section 3 on both sides of the compressed air channel 5 so in the direction of the textile web 2 before and behind the compressed air channel 5, further suction channels 7 are arranged. The suction channel 7 shown on the left is comparatively small because it only has to absorb the reflected air. The following in the web running direction, that is shown on the right suction port 7 in the upper housing portion 3, in contrast, is shown larger. This is intended to make borrowed that a larger amount of air is sucked through this suction channel 7, namely not only hot air, which is reflected from the upper compressed air channel 5, but also hot air flowing from a lower compressed air channel 5, which is arranged in the lower housing section 4 and whose air outlet nozzles 6 are arranged below the upper right suction channel 7.
Die bislang erläuterten Druckluft- und Saugkanäle 5 und 7 sind in einem linken Abschnitt des Luftkastens 1 angeordnet, der als Temperatur-Aufheizzone A bezeichnet wird. Dieser Temperatur- Aufheizzone A ist in Bahnlaufrichtung nachgeschaltet eine Temperatur-Haltezone H vorgesehen, in welcher keine weitere Aufheizung der Textilbahn 2 erfolgt, sondern das in der Aufheizzone A erreichte Temperaturniveau lediglich gehalten wird, um eine Kristallisation des textilen Materials zu ermöglichen. The previously discussed compressed air and suction channels 5 and 7 are arranged in a left portion of the air box 1, which is referred to as a temperature-heating zone A. This temperature heating zone A downstream of the web running direction, a temperature holding zone H is provided, in which no further heating of the textile web 2 takes place, but the temperature level reached in the heating zone A is merely maintained to allow crystallization of the textile material.
Heißluft, die aus den Luftaustrittsdüsen 6 des unteren Druckluftkanals 5 im unteren Gehäuseabschnitt 4 austritt und von der Textilbahn 2 reflektiert wird, wird einerseits durch den Saugkanal 7 abgesaugt, der sich unmittelbar neben dem unteren Druckluft- kanal 5 innerhalb der Aufheizzone A befindet und daher links von dem unteren Druckluftkanal 5 dargestellt ist. Reflektierte Heißluft, die jedoch nicht entgegen der Bahnlaufrichtung strömt, sondern gemeinsam mit der Textilbahn 2 durch die Temperatur- Haltezone H strömt, wird am Ende des Luftkastens 1 durch ei- nen dort vorgesehenen, wiederum vergleichsweise klein bemessenen Saugkanal 7 angesaugt, der im unteren Gehäuseabschnitt 4 angeordnet ist. Auch Heißluft, die aus den Luftaustrittsdüsen 6 durch die Textilbahn hindurchgetreten ist und nicht durch einen direkt gegenüberliegenden Saugkanal 7 angesaugt wird, wird durch diesen vergleichsweise klein bemessenenHot air, which emerges from the air outlet nozzles 6 of the lower compressed air channel 5 in the lower housing section 4 and is reflected by the textile web 2, is sucked off on the one hand by the suction channel 7, which is located directly next to the lower compressed air channel 5 within the heating zone A and therefore left from the lower compressed air channel 5 is shown. Reflected hot air, which, however, does not flow counter to the web running direction but flows together with the textile web 2 through the temperature holding zone H, is sucked in at the end of the air box 1 by a suction channel 7 provided there, again comparatively small, which is located in the lower housing section 4 is arranged. Also, hot air that has passed through the textile web from the air outlet nozzles 6 and is not sucked in by a directly opposite suction channel 7, is dimensioned by this comparatively small
Saugkanal 7 am Ende des Luftkastens 1 angesaugt. Energiever- luste, die durch aus dem Luftkasten 1 austretende erwärmte Luft bedingt sind, werden möglichst vermieden. Suction channel 7 sucked at the end of the air box 1. energy Lusts that are caused by exiting the air box 1 heated air are avoided as possible.
Wahlweise kann abweichend von dem dargestellten Ausführungsbeispiel auch ein weiterer Absaugkanal 7 mit vergleichweise klein bemessenem Querschnitt am Ende der Temperatur- Haltezone H im oberen Gehäuseabschnitt 3 angeordnet sein, also gegenüber von dem unteren, vergleichsweise klein bemessenen Saugkanal 7. Alternatively, notwithstanding the illustrated embodiment, a further suction channel 7 may be arranged with comparatively small sized cross-section at the end of the temperature holding zone H in the upper housing section 3, ie opposite the lower, relatively small sized suction channel. 7
Zudem ist aus Übersichtlichkeitsgründen nicht dargestellt, dass dort, wo die Textilbahn 2 in den Luftkasten 1 eintritt und am anderen Ende wieder aus dem Luftkasten 1 austritt, zusätzliche Dichtungselemente vorgesehen sind, welche Luftverluste zu minimieren helfen. In addition, it is not shown for reasons of clarity that where the textile web 2 enters the air box 1 and exits the air box 1 at the other end, additional sealing elements are provided, which help to minimize air losses.
In der Temperatur-Aufheizzone A ist der obere Gehäuseabschnitt 3 zur Textilbahn 2 hin durch eine obere Tunnelwand 9 geschlossen und gegenüberliegend ist in gleicher weise der untere Gehäuseabschnitt 4 zur Textilbahn 2 hin durch eine untere Tunnelwand 10 geschlossen, so dass sich in der Temperatur- Haltezone H ein flacher so genannter Bahntunnel 1 1 ergibt, durch den die reflektierte Heißluft strömt, die aus dem unteren Druckluftkanal 5 stammt. Diese Luft wird nicht in der Temperatur-Haltezone H im oberen Gehäuseabschnitt 3 oder im unteren Gehäuseabschnitt 4 verwirbelt, sondern liegt der Textilbahn 2 an, bis sie kurz vor dem Ende des Luftkastens 1 in den rechten unteren Saugkanal 7 eingesaugt wird. In ähnlicher Weise kann auch die oberhalb der Textilbahn 2 befindliche Luft auch durch den Bahntunnel 1 1 hindurch geführt werden, wenn der weiter oben erwähnte, zusätzliche obere Saugkanal 7 abweichend von dem dargestellten Ausführungsbeispiel in der Temperatur- Haltezone H im oberen Gehäuseabschnitt 3 angeordnet ist. Die Darstellung der Luftaustrittsdüsen 6 und der Luftansaugöff- nungen 8 ist rein schematisch, so dass sowohl die Anzahl als auch die Position der Luftaustrittsdüsen 6 bzw. Luftansaugöff- nungen 8 davon abweichen kann. Statt der jeweils einen dargestellten Luftaustrittsdüse 6 bzw. Luftansaugoffnung 8 kann eine Anordnung von zwei oder mehreren solchen vorgesehen sein. Um eine Luftströmung zu begünstigen, die senkrecht durch die Fläche der Textilbahn 2 strömt, kann vorgesehen sein, dass eineIn the temperature heating zone A, the upper housing section 3 is closed to the textile web 2 through an upper tunnel wall 9 and opposite is in the same way the lower housing section 4 closed to the textile web 2 through a lower tunnel wall 10, so that in the temperature holding zone H a flat so-called railway tunnel 1 1 results, through which the reflected hot air flows, which comes from the lower compressed air channel 5. This air is not swirled in the temperature-holding zone H in the upper housing section 3 or in the lower housing section 4, but is the textile web 2 until it is sucked into the right lower suction channel 7 just before the end of the air box 1. Similarly, the air located above the textile web 2 can also be passed through the railway tunnel 1 1, if the above-mentioned, additional upper suction channel 7 is arranged differently from the illustrated embodiment in the temperature holding zone H in the upper housing section 3. The illustration of the air outlet nozzles 6 and the Luftansaugöff- openings 8 is purely schematic, so that both the number and the position of the air outlet nozzles 6 and Luftansaugöff- 8 may deviate from it. Instead of the air outlet nozzle 6 or air intake 8 shown in each case, an arrangement of two or more such can be provided. In order to promote an air flow which flows vertically through the surface of the textile web 2, it can be provided that a
Luftaustrittsdüse 6 einer Luftansaugoffnung 8 genau gegenüberliegend angeordnet ist. Air outlet nozzle 6 an air intake 8 is located exactly opposite.
