Abstract

A yarn-treatment device comprises a column of chambers connected by yarn-inlet and yarn-outlet channels. The chambers contain a stream treatment chamber (5) with a steam inlet (5.1) and a condensate outlet (5.2), and mixing chambers (4, 6) operating upstream and downstream of the treatment chamber. Each mixing chamber has an air inlet (4.1, 6.1) and a condensate outlet (4.2, 6.2). The yarn inlet and outlet channels of the stream treatment chamber have an opening cross section to make a pneumatic yarn threading-in, and to control the exchange of air and steam between the chambers, such that the steam-air-mixture atmosphere sets in, to close the entrance of air into the steam treatment chamber. The steam-air-mixture atmosphere is controlled by regulation devices that regulate the steam and air supply to the steam treatment chamber or respective mixing chambers. The downstream mixing chamber is connected to a cooling and drying chamber (7), and includes a jet connected with protection plates. The treatment device further comprises yarn delivery rollers (11, 12) at upper and lower ends of the column of chambers.

Description

Die Erfindung betrifft eine Vorrichtung zur Behandlung eines laufenden Fadens mit einem unter Druck stehenden dampfförmigen Behandlungsmedium. Diese Vorrichtung kann insbesondere als Thermofixiereinrichtung dienen, bei der der laufende Faden in einer Dampfbehandlungszone erhitzt und anschließend in einer Kühl- und Trocknungszone so abgekühlt und getrocknet wird, dass er seinen in der Dampfbehandlungszone erreichten Zustand beibehält.The invention relates to a device for the treatment of a running thread with a pressurized vapor treatment medium. These Device can serve in particular as a heat-setting device, in which the Running thread heated in a steam treatment zone and then in a Cooling and drying zone is cooled and dried so that it is in his maintains the steam treatment zone reached state.

Der Begriff "Dampf" steht stellvertretend auch für andere gasförmige Medien.The term "steam" is representative of other gaseous media.

Ziel einer derartigen Behandlung ist es, durch eine definierte Schrumpfung oder Dehnung das Volumen bzw. die Dichte eines Textilfadens zu beeinflussen und zu steuern, wobei beispielsweise durch eine gezielte Schrumpfung das Volumen des Textilfadens, der sog. Bausch, erhöht werden kann. Wesentlich dabei ist es, die Optimierung und Konservierung der dem Faden in der Dampfbehandlungszone erteilten physikalischen Effekte durch Abkühlung und Trocknung des behandelten Fadens möglichst vollständig aufrechtzuerhalten, und zwar auch bei und nach dem Aufspulen des Fadens zu einer Spule.The aim of such treatment is, by a defined shrinkage or Elongation to influence and increase the volume or density of a textile thread control, for example, by a targeted shrinkage, the volume of Textile thread, the so-called Bausch, can be increased. It is essential that the Optimization and conservation of the thread in the steam treatment zone granted physical effects by cooling and drying of the treated Thread as fully as possible, even during and after the Winding the thread into a spool.

In der EP 1 348 785 ist eine Vorrichtung zur Behandlung eines laufenden Fadens mit einem dampfförmigen Behandlungsmedium beschrieben. Diese Vorrichtung enthält mehrere säulenartig übereinander angeordnete Fadenbehandlungsstrecken und -kammern. Ein wesentliches Element dieser Vorrichtung ist die eigentliche mit einem Dampfeinlass versehene Dampfbehandlungsstrecke, der Trennkammern vor- und nachgeschaltet sind, die Lufteinlässe und Kondensatauslässe aufweisen. Die Fadeneinlauf- und Fadenauslaufkanäle dieser Kammern haben einen Öffnungsquerschnitt haben, der den Austausch von Luft und Dampf zwischen den Kammern so regelt, dass sich in diesen Trennkammern eine Dampf-Luft-Mischatmosphäre einstellt, die den Eintritt von Luft in den Dampfbehandlungsraum weitgehend unterbindet. An die dem Dampfbehandlungsraum nachgeschaltete Trennkammer schließt sich eine Kühlstrecke in Form eines relativ engen Fadenlaufkanals an, in den Kühlluft eingeblasen werden kann. Der Nachteil dieser bekannten Vorrichtung besteht darin, dass die Kühllufteinspeisung in relativ großem Abstand hinter der Dampfbehandlungsstrecke erfolgt und die Kühlung außerdem in einem sehr engen Kanal stattfindet, so dass der Kühl- und Trocknungseffekt nur sehr gering ist. Dieses ist dadurch bedingt, dass die eingespeiste Kühlluft über einen größeren Abstand entgegen der Fadenlaufrichtung in Richtung der Dampfbehandlungsstrecke strömen muss, so dass es zu keiner spontanen Abkühlung bzw. Abschreckung des Fadens hinter der Dampfbehandlungsstrecke kommt. Dabei ist in Frage gestellt, in welchem Umfang in der der Dampfbehandlungsstrecke nachgeschalteten Trenn- und Mischkammer überhaupt eine Kondensatbildung und damit eine Kondensatabscheidung möglich ist, da der Kühllufteinlass über einen relativ großen Abstand nur durch den relativ engen Fadenlaufkanal mit dieser Trennkammer in Verbindung steht. Besonders nachteilig ist es, dass während des Kühlprozesses gebildetes Kondensat sich im wesentlichen nur an den Wänden des engen Fadenlaufkanals niederschlagen kann, so dass dieses Kondensat weitgehend wieder von dem an sich zu trocknenden Faden mitgerissen wird. Das hat zur Folge, dass der die Vorrichtung verlassende Faden den durch die Thermofixierbehandlung bezweckten und erreichten Zustand nicht beibehält.EP 1 348 785 discloses a device for treating a running suture described with a vaporous treatment medium. This device contains several columnar superimposed thread treatment sections and chambers.

The disadvantage of these known Device is that the cooling air supply in a relatively large Distance is done behind the steam treatment line and the cooling also takes place in a very narrow channel, so that the cooling and drying effect only is very low. This is due to the fact that the injected cooling air over a greater distance counter to the thread running direction in the direction of the steam treatment line must flow, so that there is no spontaneous cooling or Deterrence of the thread comes behind the steam treatment line. It is questioned to what extent in the downstream of the steam treatment line Separating and mixing chamber at all a condensation and so that a condensate separation is possible because the cooling air inlet via a relatively large distance only through the relatively narrow yarn path channel with this Separation chamber is in communication. It is particularly disadvantageous that during the Condensate formed essentially only on the walls of the cooling process narrow thread channel, so that this condensate largely again entrained by the thread to be dried. That has to As a result, the thread leaving the device will be damaged by the heat-setting treatment intended and achieved state not maintained.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der in der EP 1 348 785 A1 beschriebenen Art so zu verbessern, dass der nach der Dampfbehandlung aus der Vorrichtung austretende Faden so weit abgekühlt und getrocknet ist, dass bei und nach dem Aufwickeln zu einer Spule die Fadenqualität verschlechternden Zustandsänderungen weitgehend ausgeschlossen sind.The invention is based on the object, a device of EP 1 348 785 A1 type so that after steam treatment from the device emerging thread is cooled and dried so far that during and after winding into a bobbin the thread quality deteriorates State changes are largely excluded.

    Die Dampfbehandlungskammer 5 ist mit Temperaturfühlern TD ausgerüstet, die über ein Regelorgan 22 die Dampfzufuhr in die Dampfbehandlungskammer 5 steuern. Die beiden Regelorgane 21a, 21b sind mit dem Regelorgan 22 verknüpft, um gemeinsam die jeweiligen Druckwerte und damit die Temperaturwerte in den einzelnen Kammern zu regeln bzw. zu steuern.The steam treatment chamber 5 is equipped with temperature sensors T D , which control the steam supply into the steam treatment chamber 5 via a control element 22. The two control elements 21a, 21b are linked to the control element 22 in order to jointly regulate or control the respective pressure values and thus the temperature values in the individual chambers.

    In der Kühlkammer 6 ist oberhalb der Düse 8 ein vorzugsweise glockenförmig nach oben gewölbter, bis zur Kammerinnenwand reichender Boden 9 angeordnet, der eine zentrisch liegende Fadenöffnung 9.1 und im Bereich seines unten liegenden, an die Kammerinnenwand angrenzenden Randes mindestens eine Kondensatabflussöffnung 9.2 aufweist. Bei dieser Kammer 6 liegt die Mischzone im wesentlichen oberhalb des Bodens 9, während die Kühlzone unterhalb dieses Bodens liegt. Der glockenförmige Boden 9 führt bereits zu einer weitgehenden Abschottung der unterhalb dieses Bodens befindlichen Kühlzone gegen einen Dampfeintritt, da von dem Faden mitgerissene Dampfpartikel im Bereich der Öffnung 9.1 von dem Faden abgestreift werden. Oberhalb dieses Bodens 9 findet bereits eine erste Kondensatbildung statt, und das dabei gebildete Kondensat fließt durch die Kondensatabflussöffnung 9.2 am Innenwandbereich der Kammer 6 zu dem Kondensatauslass 6.2.In the cooling chamber 6, a preferably bell-shaped above the nozzle 8 upwardly curved bottom 9 extending to the inner wall of the chamber, the centrally located thread opening 9.1 and in the area of its underlying, at least one condensate drain opening adjacent the chamber inner wall edge 9.2. In this chamber 6, the mixing zone is substantially above the bottom 9, while the cooling zone below this bottom lies. The bell-shaped bottom 9 already leads to a large extent foreclosure the cooling zone located below this floor against a steam inlet, because of the thread entrained vapor particles in the region of the opening 9.1 be stripped off the thread. Above this floor 9 already finds one first condensation takes place, and the condensate formed thereby flows through the Condensate drain opening 9.2 on the inner wall portion of the chamber 6 to the Condensate outlet 6.2.

    Die Kühl- und Trocknungskammer 7 enthält mindestens einen vorzugsweise glockenförmig nach oben gewölbten, bis zur Kammerinnenwand reichenden Boden 10, der eine zentrisch angeordnete Fadenöffnung und im Bereich seines unteren, an die Innenwand der Kammer 7 angrenzenden Randes mindestens eine Kondensatabflussöffnung 10.1 hat. Es können vorzugsweise bis zu vier oder mehr dieser glockenförmigen Böden 10 vorgesehen sein.The cooling and drying chamber 7 contains at least one preferably bell-shaped vaulted up to the chamber inner wall reaching ground 10, which has a centrally arranged thread opening and in the region of its lower, at least one condensate drain opening adjoining the inner wall of the chamber 7 edge 10.1 has. It may preferably be up to four or more of these be provided bell-shaped bottoms 10.

    Der Kondensatauslass 5.2 der Dampfbehandlungskammer 5 ist über eine Kondensatleitung 5.3 an einen Kondensatbehälter 15 angeschlossen, dessen Auslass durch ein steuerbares Ventil 16 verschließbar ist, dessen Ventilkörper 16.1 gegen die Kraft einer Feder 17 verstellbar ist.The condensate outlet 5.2 of the steam treatment chamber 5 is via a condensate line 5.3 connected to a condensate tank 15 whose outlet can be closed by a controllable valve 16, the valve body 16.1 against the force of a spring 17 is adjustable.

    Die Kondensatauslässe 4.2 bzw. 6.2 bzw. 7.2 der Kammern 4 und 6 sowie der Kühl- und Trockenkammer 7 sind über Leitungen 4.3, 6.3 bzw. 7.3 an Abflusskanäle 18 bzw. 19 bzw. 20 der Kondensatablasseinrichtung 23 angeschlossen, die jeweils Drosseln 18.1 bzw. 19.1 bzw. 20.1 enthalten.The condensate outlets 4.2 and 6.2 or 7.2 of the chambers 4 and 6 and the Cooling and drying chamber 7 are via lines 4.3, 6.3 and 7.3 to drain channels 18 and 19 and 20 of the condensate discharge device 23 connected, the each contain throttles 18.1 or 19.1 or 20.1.

    Die obere Mischkammer 4, der durch den Lufteinlass 4.1 Druckluft zugeführt wird, dient zur Abschottung der Dampfbehandlungskammer 5, um weitgehend zu verhindern, dass Luft in die Dampfbehandlungskammer 5 eindringt, indem sich in dieser Mischkammer 4 durch geeignete Steuerung der in diese Kammer 4 einströmenden Luft eine Dampf-/Luft-/Mischatmosphäre einstellt.The upper mixing chamber 4, fed through the air inlet 4.1 compressed air serves to partition the steam treatment chamber 5, to largely prevent air from entering the steam treatment chamber 5 by moving into this mixing chamber 4 by suitable control of the inflowing into this chamber 4 Air sets a steam / air / mixed atmosphere.

    Die auf die Dampfbehandlungskammer 5 folgende Kühlkammer 6 dient ebenso wie die obere Mischkammer 4 zum Abschotten der Dampfbehandlungskammer 5 gegen das Eindringen von Luft von unten her. Indem in dieser Kammer 6 die Kühlluft durch das Düsen-/Abschirmplattensystem 13/14 möglichst dicht an den Faden herangeführt wird, erfolgt ein rasches Abkühlen des Fadens, um einen möglichst hohen Thermofixiereffekt zu bewirken. Innerhalb dieser Kammer 6 wird gleichzeitig von dem Faden mitgeführte Feuchte aus dem Faden ausgetrieben, d.h. der Faden wird bereits in einem gewissen Umfang getrocknet. Der oberhalb des Systems 13/14 befindliche glockenförmige Boden 9 führt auch durch "Abstreifen" von Dampf zu einer Dampfabscheidung.The cooling chamber 6 following the steam treatment chamber 5 also serves as the upper mixing chamber 4 for Abschotten the steam treatment chamber. 5 against the ingress of air from below. By in this chamber 6 the Cooling air through the nozzle / shield plate system 13/14 as close as possible to the Thread is introduced, there is a rapid cooling of the thread to a to cause the highest possible heat-setting effect. Within this chamber 6 At the same time moisture carried away by the thread is expelled from the thread, i.e. the thread is already dried to a certain extent. The above the system 13/14 located bell-shaped bottom 9 also performs "Stripping" from steam to a vapor deposition.

    Infolge der Verwendung von Keramikmaterial werden die beiden Kammern 4 bzw. 6 gegenüber der Dampfbehanldungskammer 5 thermisch isoliert. Sie werden daher nicht oder nur geringfügig von der anschließenden Dampfbehandlungskammer aufgewärmt, so dass auch nur eine geringe Wärmeenergiemenge diese Kammern 4 bzw. 6 als Energieverlust verlässt. Der Fadendurchlaufkanal zwischen der Dampfbehandlungskammer 5 und der darauf folgenden Kammer 6 ist relativ lang ausgeführt, wodurch eine mechanische Abschottung der Dampfbehandlungskammer 5 bewirkt wird.Due to the use of ceramic material, the two chambers 4 or 6 thermally insulated from the Dampfbehanldungskammer 5. you will be therefore not or only slightly from the subsequent steam treatment chamber warmed up, so that even a small amount of heat energy this Chambers 4 and 6 leaves as energy loss. The thread passage between the steam treatment chamber 5 and the subsequent chamber 6 is relative long running, creating a mechanical partitioning of the steam treatment chamber 5 is effected.

    Die Kühlluft wird durch die vorzugsweise aus thermisch isolierendem Material bestehende Düse 13 direkt quer zum frei laufenden Faden in die Kühlkammer 6 eingeblasen. Diese Kühlluft trifft direkt auf den vorbeilaufenden Faden auf, was bei geringen Luftströmungen zu einem größtmöglichen Kühl- und auch Trocknungseffekt führt. Durch die Kühlluft werden Restdampfpartikel zwischen den Faserkapilaren des Fadens weitgehend aus dem Faden ausgetrieben, so dass der Faden getrocknet wird. Die Kühlluftströmung muss durch geeignete Auswahl des Düsenauslasses so eingestellt werden, dass ein Verwirbeln des Fadens vermieden wird.The cooling air is through the preferably made of thermally insulating material existing nozzle 13 directly across the free-running thread in the cooling chamber. 6 blown. This cooling air hits directly on the passing thread, which at low air flows to the largest possible cooling and also Drying effect leads. Due to the cooling air residual vapor particles between the Faserkapilaren of the thread largely expelled from the thread, so that the thread is dried. The cooling air flow must be selected appropriately the nozzle outlet are adjusted so that a swirling of the thread avoided becomes.

    Die anschließende Kühl- und Trocknungskammer 7, in die Kühlluft aus der Kammer 6 durch den diese beiden Kammern verbindende Fadenkanal eintritt, bewirkt ein weiteres Abkühlen und Trocknen. Der von dem Faden noch in diese Kühl- und Trocknungskammer 7 mitgerissene Restdampf wird im Bereich der glockenförmig nach oben gewölbten Böden 10 aus dem Faden ausgetrieben, wobei das Restkondensat durch den Kondensatauslass 7.2 und durch die Leitung 7.3 abgelassen wird.The subsequent cooling and drying chamber 7, in the cooling air from the Chamber 6 enters through the connecting these two chambers thread channel causes another cooling and drying. The one of the thread still in this Cooling and drying chamber 7 entrained residual steam is in the range bell-shaped upwardly curved bottoms 10 expelled from the thread, wherein the residual condensate through the condensate outlet 7.2 and through the line 7.3 is drained.

    Die Kühl- und Trockenkammer 7 ist mittels Rippen geometrisch so ausgeführt, dass eine maximale thermische Abschirmung erfolgt, d.h. diese Kühlkammer 7 wird in geringstmöglichem Umfang durch den von dem Faden mitgerissenen Restdampf erwärmt.The cooling and drying chamber 7 is geometrically designed by means of ribs, that maximum thermal shielding occurs, i. this cooling chamber 7 is minimized by the residual steam entrained by the thread heated.

    Das während des Aufwärmzyklus beim Einströmen des Dampfes in die Behandlungskammer 5 entstehende Kondensat wird in dem Kondensatbehälter 15 aufgefangen und nach Bedarf nach dem Erreichen der Betriebstemperatur TD in der Kammer 5 durch kurzes Öffnen des Ventils 16 abgelassen.The resulting during the warm-up cycle when the steam flows into the treatment chamber 5 condensate is collected in the condensate tank 15 and discharged as needed after reaching the operating temperature T D in the chamber 5 by briefly opening the valve 16.

    Wesentliche Merkmale der Verfahrensführung bestehen darin, dass innerhalb der Behandlungsstrecke folgende Merkmale beachtet werden:

    • spannungsloses Führen des Fadens
    • genaue Temperaturführung
    • exakte Länge des Fadenweges durch die Dampf- oder Gasbehandlungszone;
    • ausreichende und spontane Abkühlung des zum Zwecke der Thermofixierung mit Dampf behandelten Fadens, bevor der Faden wieder mechanisch belastet werden kann;

    • sichere und kostengünstige Ausführung des Systems;
    • sauberes Anlaufen und Ausscheiden der einzelnen Behandlungsstrecke unter Berücksichtigung der Kondensatableitung bei einer Dampfbehandlung.
    Essential features of the process management are that the following features are observed within the treatment section:
    • tensionless guiding of the thread
    • accurate temperature control
    • exact length of the thread path through the steam or gas treatment zone;
    • sufficient and spontaneous cooling of the heat-setting treated with steam thread before the thread can be mechanically loaded again;
    • uniform effect of temperature, speed and cooling of all treatment lines of a multi-station machine;
    • safe and cost-effective implementation of the system;
    • clean start-up and elimination of the individual treatment section, taking into account the condensate drainage during a steam treatment.

    Das Verfahren wird als Themofixierverfahren beschrieben, bei dem der Dampfbehandlungskammer 5 Sattdampf mit einer Temperatur von ca. 135°C durch eine Dampfleitung 36 zugeführt wird, die an eine Dampf-Zentralleitung 33 angeschlossen ist, an die gemäß Figur 3 über Einzelanschlussleitungen 36a - 36x weitere Behandlungsstrecken angeschlossen sind.The method is described as a theme fixing method in which the steam treatment chamber 5 saturated steam with a temperature of about 135 ° C by a Steam line 36 is supplied, which is connected to a steam central line 33 is, according to Figure 3 via individual connection lines 36a - 36x further treatment routes are connected.

    In vergleichbarer Weise sind die Kammern 4 und 6 über Einzel-Anschlussleitungen 35 bzw. 37 an Zentralleitungen 32 bzw. 34 angeschlossen. An beide Zentralleitungen 32, 34 sind Einzel-Anschlussleitungen 35a - x bzw 37a - x angeschlossen. Die Druckluftleitungen 35 bzw. 37 sind mit Absperrventilen 4.4 bzw. 6.4 ausgerüstet, die Dampfleitung 36 enthält ein Absperrventil 5.4. Similarly, the chambers 4 and 6 are via individual connection lines 35 and 37 connected to central lines 32 and 34, respectively. To both central lines 32, 34 are single connection lines 35a - x or 37a - x connected. The compressed air lines 35 and 37 are 4.4 or 6.4 with shut-off valves equipped, the steam line 36 includes a shut-off valve 5.4.

    Erfindungsgemäß lässt man jeden Einzelfaden F im wesentlichen spannungsfrei durch die oben beschriebene Vorrichtung laufen.According to the invention, each monofilament F is essentially free of tension through the device described above.

    Zur Regelung der Dampftemperatur und der Drucklufttemperaturen dienen Dampftemperaturfühler TD im Bereich der Dampfbehandlungskammer 5 und Lufttemperaturfühler TK in einer der oberen Kammer 4 vorgeschalteten Vorkammer 3 und in der Kühl- und Trockenkammer 7. Die ermittelten Temperaturen sind die Regelgrößen für die an die Zentralleitungen 32, 33, 34 angeschlossenen Regelorgane (Zentralregler) 21a, 22 und 21b. Ein Block "Steuerung" ist über nicht dargestellte Leitungen an die Temperaturfühler TK und TD und an die Lieferwerke 11 und 12 angeschlossen. Bei Unter- oder Überschreiten vorgegebener Temperatur-Toleranzbereiche, insbesondere in den Kammern 3 und 7, wird die einzelne Fadenbehandlungsstrecke mittels der Ventile 4.4, 5.4 und 6.4 von den Zentralleitungen 32 abgeschaltet, wobei der Durchlauf des Fadens F durch die Vorrichtung durch Abschalten der Lieferwerke 11, 12 unterbrochen wird. Bei Auslaufen des Fadens oder bei Fadenbruch oder bei Ausfall eines Lieferwerks erfolgt ebenfalls über den Block "Steuerung" das Schließen der Ventile 4.4, 5.4 und 6.4, die mittels Steuerleitungen 4.6, 5.6 bzw. 6.6 an diesen Block angeschlossen sind. Während der Aufwärmphase wird die Dampfbehandlungskammer 5 auf die erforderliche Behandlungstemperatur erwärmt, wobei die Temperatur mittels der Dampftempcraturfühler TD gemessen wird. Während der Aufwärmphase werden die der Kammer 5 vor- und nachgeschalteten Kammern 4 und 6 derart mit Druckluft beaufschlagt, dass nach Aufbau einer bestimmten Luft-Dampf-Mischatmosphäre in diesen Kammern 4 und 6 im wesentlichen kein weiterer Dampf mehr aus der Kammer 5 in diese Kammern eintreten kann. Dabei ist es wesentlich, dass sich in den Kammern 4 und 6 bildenden Kondensat kontinuierlich abgeleitet wird, ebenso wie das sich in der Kammer 5 bildende Kondensat.To control the steam temperature and the compressed air temperatures serve steam temperature sensor T D in the steam treatment chamber 5 and air temperature sensor T K in an upper chamber 4 upstream antechamber 3 and in the cooling and drying chamber 7. The temperatures determined are the control variables for the to the central lines 32nd , 33, 34 connected control elements (central controller) 21a, 22 and 21b. A block "control" is connected via lines, not shown, to the temperature sensors T K and T D and to the delivery mechanisms 11 and 12. When falling below or exceeding predetermined temperature tolerance ranges, in particular in the chambers 3 and 7, the individual thread treatment section is switched off by the valves 4.4, 5.4 and 6.4 of the central lines 32, wherein the passage of the thread F by the device by switching off the delivery mechanisms 11th , 12 is interrupted. When the thread runs out, or if the thread breaks or a delivery system fails, the "Control" block also closes the valves 4.4, 5.4 and 6.4, which are connected to this block via control lines 4.6, 5.6 and 6.6. During the warm-up phase, the steam treatment chamber 5 is heated to the required treatment temperature, the temperature being measured by means of the steam temperature sensors T D. During the warming-up phase, the chambers 4 and 6 upstream and downstream of the chamber 5 are subjected to compressed air in such a way that, after a certain air-steam mixed atmosphere has been built up in these chambers 4 and 6, substantially no further vapor is released from the chamber 5 into these chambers can occur. It is essential that in the chambers 4 and 6 forming condensate is continuously discharged, as well as the forming in the chamber 5 condensate.

    Die Regelung der jeweiligen Luft- und Dampfdrücke erfolgt zentral nach folgendem Modus:
    Die Temperaturfühler TD in der Kammer 5 zeigen das Erreichen der erwünschten Behandlungtemperatur - z. B. ca. 135° als Sattdampftemperatur - an, die zuvor am Regelorgan (Zentralregler) 22 zentral eingestellt worden ist. Diese Temperatur bildet die Führungsgröße und muss innerhalb eines bestimmten Toleranzbereiches liegen. Eine Vergleichskontrolle erfolgt mittels eines Temperaturfühlers TL in der Dampfleitung 36.    The control of the respective air and vapor pressures is done centrally according to the following mode:
    The temperature sensor T D in the chamber 5 show the achievement of the desired treatment temperature -. B. about 135 ° as saturated steam temperature - on, which has been previously adjusted centrally on the control element (central controller) 22. This temperature is the reference variable and must be within a certain tolerance range. A comparison check is carried out by means of a temperature sensor T L in the steam line 36.

    Mittels des Temperaturfühlers TK in der Kammer 7 wird festgestellt, ob in dieser Kammer eine durch physikalische Effekte bedingte bestimmte Temperatur unterhalb der Dampftemperatur TD herrscht. Überschreitet die Temperatur in der Kammer 7 einen bestimmten Toleranzbereich, z. B. von ca. 50 - 70°C, muss der Luftdruck in der Kammer 7 zentral in kleinen Schritten entsprechend erhöht werden, wodurch der Kühleffekt stärker wird. Dabei darf die Temperatur TD nicht ansteigen.By means of the temperature sensor T K in the chamber 7 it is determined whether in this chamber due to physical effects certain temperature below the steam temperature T D prevails. If the temperature in the chamber 7 exceeds a certain tolerance range, for. B. of about 50 - 70 ° C, the air pressure in the chamber 7 must be increased centrally in small steps accordingly, whereby the cooling effect is stronger. The temperature T D must not rise.

    Wird die Temperatur TD in der Behandlungskammer deutlich unterschritten, so liegt ein technischer Defekt vor, zum Beispiel bedingt durch Undichtigkeiten, so dass die einzelne Behandlungsstrecke stillgesetzt werden muss.If the temperature T D in the treatment chamber falls well below, then there is a technical defect, for example due to leaks, so that the individual treatment route must be shut down.

    Wird die untere Temperaturgrenze von TK unterschritten, so wird der entsprechende Luftdruck in der Kühlzone zentral und feinstufig abgesenkt, so dass der Dampf in der Mischzone ein größeres Gewicht erhält und die Kühllufttemperatur in der Kammer 7 sich geringfügig erhöht.If the lower temperature limit of T K is exceeded, the corresponding air pressure in the cooling zone is lowered centrally and in a finely graduated manner so that the steam in the mixing zone receives a greater weight and the cooling air temperature in the chamber 7 increases slightly.

    Der Kühlluftdruck in den Luftleitungen 35 und 37 und damit in den Kammern 4 und 6 muss unabhängig voneinander mittels der Regler 21 a bzw. 21 b geregelt werden, weil der durch die Kammer 5 laufende Faden das Dampfmedium mit sich reißt und damit die Temperaturzone in Fadenlaufrichtung verschiebt, was in der Kammer 6 zu von der Kammer 4 abweichenden Temperaturen führt.The cooling air pressure in the air lines 35 and 37 and thus in the chambers. 4 and 6 must be controlled independently by means of the controller 21 a and 21 b be because the current through the chamber 5 thread the vapor medium with it rips and thus shifts the temperature zone in the direction of thread travel, which in the Chamber 6 leads to deviating from the chamber 4 temperatures.

    Der Vorteil dieser Regelung besteht darin, dass bei großen zentralen Luft- und Dampfleitungen und demgegenüber kleinen Einzel-Anschlussleitungen 35, 37, 37 im Bereich der einzelnen Behandlungsstrecke nur ein einziger handelsüblicher Zentralregler 38 bzw. 39 bzw. 40 erforderlich ist. Die einzelnen Behandlungsstrecken haben damit einen sehr einfachen Aufbau.The advantage of this scheme is that in large central air and Steam lines and, on the other hand, small individual connection lines 35, 37, 37 in the area of the individual treatment section only a single commercial Central controller 38 or 39 or 40 is required. The individual treatment routes have a very simple structure.
