Description

Heizeinrichtung Heating device
Die Erfindung betrifft eine Heizeinrichtung zum Erhitzen eines laufenden Fadens in einer Texturiermaschine mit den Merkmalen gemäß des Oberbegriffs aus Anspruch 1.The invention relates to a heating device for heating a running thread in a texturing machine with the features according to the preamble of claim 1.
Derartige Heizeinrichtungen werden insbesondere zum Kräuseln synthetischer Fäden in einer Texturiermaschine, durch welche der laufende Faden gefuhrt und gekräuselt wird, verwendet. Dabei wird der Faden in einer beheizten Nut geführt, die an ihren Wandungen auf eine Oberflächentemperatur erhitzt ist, die oberhalb der Schmelztemperatur des Fadens liegt. Hierzu sind in der Heiznut mehrere Fadenführer vorgesehen, die den Faden mit Abstand zu den Wandungen der Heiznut führen. Die Fadenführer sind an einem Träger angebracht, der auswechselbar in der Heiznut angeordnet ist.Such heating devices are used in particular for crimping synthetic threads in a texturing machine through which the running thread is passed and crimped. The thread is guided in a heated groove, which is heated on its walls to a surface temperature that is above the melting temperature of the thread. For this purpose, several thread guides are provided in the heating groove, which guide the thread at a distance from the walls of the heating groove. The thread guides are attached to a carrier which is interchangeably arranged in the heating groove.
Eine solche Heizeinrichtung ist beispielsweise aus der EP 0 731 197 (Bag. 2307) bekannt.Such a heating device is known for example from EP 0 731 197 (Bag. 2307).
Zur Fixierung des zuvor in dem Faden eingebrachten Dralls ist eine den gesamten Fadenquerschnitt erfassende intensive Wärmebehandlung erforderlich, so daß bei der bekannten Heizeinrichtung jeweils ein Faden in einer Heiznut geführt wird. Damit ist gewährleistet, daß bei den multifilen Fäden jedes der Filamente eine zur Einkräuselung intensive Wärmebehandlung erhält. Die bekannte Heizvorrichtung ist zur Wärmebehandlung mehrerer parallel verlaufender Fäden ungeeignet.In order to fix the twist previously introduced into the thread, an intensive heat treatment covering the entire thread cross section is required, so that in the known heating device a thread is guided in each heating groove. This ensures that with the multifilament threads each of the filaments receives an intensive heat treatment for crimping. The known heating device is unsuitable for the heat treatment of several threads running in parallel.
Aus der DE 196 50 677 (Bag. 2358) ist eine Heizeinrichtung bekannt, die zum Aufheizen einer laufenden Fadenschar eingesetzt wird. Hierbei wird die Fadenschar in einem Heizkanal in einer Fadenlaufebene parallel zu den Seitenwänden des Heizkanals geführt. Derartige Anordnungen sind für die Verwendung in Texturiermaschinen ungeeignet, daß aufgrund von Wärmeverlusten insbesondere zum Rand der Fadenschar hin keine gleichmäßige Wärmebehandlung zur Kräuselung der einzelnen Fäden möglich ist.A heating device is known from DE 196 50 677 (Bag. 2358), which is used for heating a running thread sheet. The thread sheet is guided in a heating duct in a thread running plane parallel to the side walls of the heating duct. Such arrangements are unsuitable for use in texturing machines because of Loss of heat, in particular towards the edge of the thread sheet, does not allow uniform heat treatment to crimp the individual threads.
Demgemäß ist es Aufgabe der Erfindung, eine Heizeinrichtung der eingangs genannten Art derart weiterzubilden, daß sowohl ein oder auch mehrere nebeneinander laufende Fäden eine gleichmäßige Wärmebehandlung erhalten.Accordingly, it is an object of the invention to develop a heating device of the type mentioned at the outset in such a way that both one or more threads running side by side receive a uniform heat treatment.
Diese Aufgabe wird durch eine Heizeinrichtung mit den Merkmalen gemäß Anspruch 1 gelöst.This object is achieved by a heating device with the features according to claim 1.
Dabei ist die Anordnung der Fadenführer innerhalb der Heiznut so gewählt, daß mehrere nebeneinander liegende Fadenlaufspuren zur Führung mehrerer Fäden gebildet werden und daß die Fäden dabei in einer im Abstand zum Nutgrund liegenden Fadenlaufebene geführt sind. Der besondere Vorteil der Erfindung liegt darin, daß unabhängig, ob ein oder mehrere Fäden in der Heizeinrichtung geführt sind, die die Fäden mit im wesentlichen gleichem Abstand zum Nutgrund geführt sind. Die Fadenlaufebene sowie der Abstand zum Nutgrund ist dabei so gewählt, daß im wesentlichen gleiche Aufheizzeiten, Aufheizintensitäten und Reibungen an jedem einzelnen Faden wirken.The arrangement of the thread guides within the heating groove is selected such that a plurality of thread running tracks lying next to one another are formed for guiding several threads and that the threads are guided in a thread running plane spaced apart from the groove base. The particular advantage of the invention is that regardless of whether one or more threads are guided in the heating device, the threads are guided at substantially the same distance from the groove base. The thread running plane and the distance to the groove base is selected so that essentially the same heating times, heating intensities and friction act on each individual thread.
Die Erfindung besitzt den besonderen Vorteil, daß bei Führung mehrerer parallel verlaufender Fäden durch eine Heiznut jeder der Fäden einer im wesentlichen gleichen Umgebungstemperatur ausgesetzt wird. Damit besteht auch die Möglichkeit, die Heizeinrichtung sowohl mit einem Faden oder auch mit mehreren Fäden zu betreiben.The invention has the particular advantage that when a plurality of threads running in parallel are guided through a heating groove, each of the threads is exposed to an essentially identical ambient temperature. It is also possible to operate the heating device with one thread or with several threads.
Gemäß einem bevorzugten Ausführungsbeispiel der Erfindung erstreckt sich die von den Fadenführern aufgespannte Fadenlaufebene, in welcher die Fäden geführt sind, im wesentlichen parallel zum Nutgrund. Dadurch werden die Fäden mit konstantem Abstand zur Heiznut geführt, so daß eine besonders gleichmäßige Temperatureinwirkung auf die Fäden erreicht wird. Durch die einseitige Öffnung der Heiznut, die im Betrieb durch einen Deckel verschlossen ist, ergibt sich ein Temperaturgefälle zwischen Nutgrund und der Deckelseite der Heiznut. Innerhalb der Nut werden die Fäden in einer Höhe innerhalb der Nut geführt, so daß Temperaturgefälle in der Heiznut keinen Einfluß auf die Temperierung der Fäden hat.According to a preferred embodiment of the invention, the thread running plane spanned by the thread guides, in which the threads are guided, extends essentially parallel to the groove base. As a result, the threads are guided at a constant distance from the heating groove, so that a particularly uniform temperature effect on the threads is achieved. Through the one-sided opening The heating groove, which is closed by a cover during operation, results in a temperature gradient between the groove base and the cover side of the heating groove. The threads are guided within the groove at a height within the groove, so that temperature drops in the heating groove have no influence on the temperature of the threads.
Um einen stabilen Fadenlauf in der Heiznut mit möglichst wenig Kontakt und somit möglichst wenig Umschlingungsreibung zu erhalten, sind die Fadenführer derart zueinander angeordnet, daß sich jeweils zick-zack-förmige Fadenlaufspuren ausbilden, in denen die Fäden geführt sind.In order to obtain a stable thread running in the heating groove with as little contact and thus as little wrap friction as possible, the thread guides are arranged in relation to one another in such a way that zigzag-shaped thread running tracks are formed, in which the threads are guided.
Dabei führt die Anordnung einer besonders bevorzugten Weiterbildung der Erfindung gemäß Anspruch 4 dazu, daß eine sehr gleichmäßige Behandlung der Fäden innerhalb der Heiznut erfolgt. Hierzu ist die Anzahl und die Anordnung der Fadenführer so gewählt, daß benachbart verlaufende Fadenlaufspuren zwischen sich einen in der Längsrichtung des Heizers gleichbleibenden Fadenabstand aufweisen.The arrangement of a particularly preferred development of the invention leads to a very uniform treatment of the threads within the heating groove. For this purpose, the number and the arrangement of the thread guides are selected so that adjacent thread running tracks have a constant thread spacing between them in the longitudinal direction of the heater.
Die besonders vorteilhafte Ausbildung der Erfindung gemäß Anspruch 5 wird bevorzugt bei Texturiermaschinen eingesetzt, bei welchen zwei Fäden vor der Aufwicklung zu einem Faden zusammengeführt werden. Bei einer derartigen Fachung sind unterschiedliche Wärmebehandlungen der Einzelfäden oftmals gewünscht, so daß auf einfache Weise verschiedene Ausführungen der Fadenlaufspuren erreicht werden.The particularly advantageous embodiment of the invention according to claim 5 is preferably used in texturing machines in which two threads are brought together to form one thread before winding. With such a fold, different heat treatments of the individual threads are often desired, so that different designs of the thread running tracks can be achieved in a simple manner.
Um zu gewährleisten, daß der in der Heiznut eingelegte Träger und daran angebrachten Fadenführer eine möglichst ungehinderte Erwärmung der Fäden ermöglicht, ist der Träger bevorzugt aus einem wärmeleitenden Material hergestellt. Die Fadenführer sind dabei aus einer Keramik hergestellt oder mit einer Keramik beschichtet, so daß sie einen hohen Verschleißwiderstand aufweisen. Dies hat insbesondere eine hohe Lebensdauer der Fadenführer zur Folge. Des weiteren besitzt Keramik die Eigenschaft, daß die bei herkömmlichen Stahlfadenführern vorhandene Tendenz zur Anlagerung von anorganischen Bestandteilen des Fadens verringert wird und zudem der Verschleiß geringer ist.In order to ensure that the carrier inserted in the heating groove and the thread guide attached to it enables the threads to be heated as freely as possible, the carrier is preferably made of a heat-conducting material. The thread guides are made of a ceramic or coated with a ceramic so that they have a high wear resistance. In particular, this has a long service life for the thread guides Episode. In addition, ceramics have the property that the tendency to accumulate inorganic constituents of the thread present in conventional steel thread guides is reduced and, in addition, the wear is less.
Bei einer besonders bevorzugten Ausführung der Erfindung besteht der Träger aus einem gut wärmeleitenden Material und ist als eine Profilschiene mit mehreren parallel verlaufenden Führungsnuten ausgebildet. Die außen liegenden Profilwände der Profilschiene sind dabei an den Nutwandungen der Heiznut angebracht. Durch diese Anordnung wird ein besonders stabiler Fadenlauf in der Heiznut erreicht. Hierbei besteht sogar die Möglichkeit, daß die Führungsnuten die Fadenlaufspur definieren und somit der Faden direkt in der Schiene geführt wird.In a particularly preferred embodiment of the invention, the carrier consists of a good heat-conducting material and is designed as a profile rail with a plurality of guide grooves running in parallel. The outside profile walls of the profile rail are attached to the groove walls of the heating groove. This arrangement results in a particularly stable thread run in the heating groove. There is even the possibility that the guide grooves define the thread track and thus the thread is guided directly in the rail.
Um eine zick-zack-förmige Fadenlaufspur zu erreichen, können dabei die Fadenführer in der Profilschiene angeformt sein. Es ist jedoch auch möglich in den Führungsnuten der Profilschiene jeweils mehrere Fadenführer aus Keramik einzusetzen. Dabei lassen sich durch Aussparungen in der Heizschiene auf einfache Weise Halteeinrichtungen für derartige Fadenführer herstellen.In order to achieve a zigzag-shaped thread running track, the thread guides can be integrally formed in the profile rail. However, it is also possible to use several ceramic thread guides in the guide grooves of the profile rail. Holders for thread guides of this type can be produced in a simple manner by means of cutouts in the heating rail.
Die Fadenführer werden bevorzugt mit einer L-förmigen Fadenleitkante ausgebildet, so daß die Abstände zwischen dem Faden und den Wandungen der Heiznut sowie zwischen dem Faden und dem Nutgrund der Heiznut durch die Fadenleitkante bestimmt sind. Auch dies ist eine Maßnahme, die zu einer Vergleichmäßigung der Temperaturbehandlung des Fadens innerhalb der Heiznut führt.The thread guides are preferably formed with an L-shaped thread guide edge, so that the distances between the thread and the walls of the heating groove and between the thread and the groove base of the heating groove are determined by the thread guide edge. This is also a measure that leads to an equalization of the temperature treatment of the thread within the heating groove.
Bei einer besonders vorteilhaften Weiterbildung der Erfindung ist die Profilschiene durch mehrere U-förmige Einzelschienen gebildet. Die Einzelschienen sind dabei an ihren gegenüberliegenden Längsseiten verbunden, so daß zwischen den einzelnen Fadenlaufspuren keine Wärmeblockade entsteht. Weitere Vorteile, Merkmale und Anwendungsmöglichkeiten der vorliegenden Erfindung werden nun anhand von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Zeichnungen näher erläutert.In a particularly advantageous development of the invention, the profile rail is formed by a plurality of U-shaped individual rails. The individual rails are connected on their opposite longitudinal sides, so that there is no heat blockage between the individual thread tracks. Further advantages, features and possible applications of the present invention will now be explained in more detail using exemplary embodiments with reference to the accompanying drawings.

Die nachfolgende Beschreibung gilt für die Figuren 1 und 2, insoweit kein ausdrücklicher Bezug zu einer der Figuren genannt ist.1 and 2 show a first exemplary embodiment of a heating device according to the invention. In Fig. 1 is a plan view and in Fig. 2 schematically shows a cross section of the embodiment of the heating device. The following description applies to FIGS. 1 and 2, insofar as no express reference is made to one of the figures.
Die Heizeinrichtung besteht aus einem langgestreckten Heizkörper 1, der eine Länge von 0,5 m bis 2 m aufweisen kann. In dem Heizkörper 1 ist eine zu einer Seite offene Heiznut 2 in Längsrichtung eingebracht. Die Heiznut 2 wird durch die Wandungen 3, 4 und 5 in dem Heizkörper 1 begrenzt. Die Wandung 5 stellt dabei den Nutgrund dar. Unterhalb des Nutgrundes 5 weist der Heizkörper 1 zwei elektrische Heizelemente 10 auf. Der Heizkörper 1 besteht aus einem sehr gut wärmeleitenden Material, so daß durch die Heizelemente 10 die Wandungen 3, 4 und 5 der Heiznut 2 erhitzt werden. In der Heiznut 2 ist ein Träger 11 eingebettet und liegt im wesentlichen bündig an der Innenoberfläche des Nutgrundes 5 an. Der Träger 11 weist auf der gegenüberliegenden Seite zum Nutgrund 5 mehrere in die Heiznut 2 emporragende Fadenführer 7 und 8 auf. Hierbei sind die Fadenführer 7 in zwei parallelen Reihen mit Abstand in Längsrichtung angeordnet und bilden zwischen sich eine Fadenlaufspur 6.1. Die Fadenführer 7 weisen jeweils eine zu einem laufenden Faden 19 gewandte Fadenleitkante 9 auf. Die Fadenlaufspur 6.1 ist dabei die von dem Faden 19 in der Heiznut 2 durchlaufene Führungsbahn. Die Fadenführer 7 sind mit ihren Fadenleitkanten 9 abwechselnd gegenüberliegend so angeordnet, so daß sich eine zick-zack-förmige Fadenlaufspur 6.1 ausbildet. Die Fadenführer 8 sind in zwei zu den Fadenführern 7 parallelen Reihen angeordnet und bilden eine Fadenlaufspur 6.2. Die Fadenführer 8 sind ebenfalls mit ihren Fadenleitkanten 9 abwechselnd gegenüberliegend mit Abstand zueinander angeordnet, so daß eine zick-zack- förmiger Fadenlaufspur 6.2 gebildet wird. Die Fadenlaufspuren 6.1 und 6.2 werden hierbei mit unterschiedlicher Anzahl von Fadenführern 7 und 8 gebildet. In der Fadenlaufspur 6.2 sind im Eingangsbereich des Heizers mehrere in kurzen Abständen hintereinander angeordnete Fadenführer 8 und im mittleren Bereich keine Fadenführer vorgesehen. Die Fadenlaufspur 6.1 wird dagegen durch eine Anzahl von Fadenführern 7 gebildet, die in ihrem Abstand gleichmäßig versetzt zueinander angeordnet sind.The heating device consists of an elongated radiator 1, which can have a length of 0.5 m to 2 m. A heating groove 2 open to one side is introduced in the longitudinal direction in the heating element 1. The heating groove 2 is limited by the walls 3, 4 and 5 in the radiator 1. The wall 5 represents the groove base. Below the groove base 5, the radiator 1 has two electrical heating elements 10. The radiator 1 consists of a very good heat-conducting material, so that the walls 3, 4 through the heating elements 10 and 5 of the heating groove 2 are heated. A carrier 11 is embedded in the heating groove 2 and lies essentially flush against the inner surface of the groove base 5. The carrier 11 has on the opposite side to the groove base 5 a plurality of thread guides 7 and 8 projecting into the heating groove 2. Here, the thread guides 7 are arranged in two parallel rows at a distance in the longitudinal direction and form a thread track 6.1 between them. The thread guides 7 each have a thread guide edge 9 facing a running thread 19. The thread running track 6.1 is the guideway through which the thread 19 runs in the heating groove 2. The thread guides 7 are arranged with their thread guide edges 9 alternately opposite one another so that a zigzag-shaped thread running track 6.1 is formed. The thread guides 8 are arranged in two rows parallel to the thread guides 7 and form a thread running track 6.2. The thread guides 8 are also arranged with their thread guide edges 9 alternately opposite one another at a distance from one another, so that a zigzag-shaped thread running track 6.2 is formed. The thread running tracks 6.1 and 6.2 are formed with different numbers of thread guides 7 and 8. In the thread running track 6.2, a plurality of thread guides 8 arranged one behind the other in short intervals are provided in the entrance area of the heater and no thread guides are provided in the central area. The thread running track 6.1, on the other hand, is formed by a number of thread guides 7, which are evenly spaced apart from one another.
In Fig. 2 sind die Fadenführer 7 und 8 in der Seitenansicht dargestellt. Die Fadenführer 7 und 8 besitzen jeweils eine L-fbrmige Fadenleitkante 9. Durch die L-fbrmige Fadenleitkante 9 wird eine in ihren Abständen zu den Nutwandungen 3 und 4 sowie dem Nutgrund 5 definierte Fadenführung vorgenommen. Durch die Fadenleitkanten 9 der Fadenführer 7 und 8 wird eine Fadenlaufebene 17 aufgespannt, die im wesentlichen parallel zu dem Nutgrund 5 ist. Damit werden die Fäden 19.1 und 19.2 auf einer Höhe durch die Heiznut 2 geführt. Bei dem in Fig. 1 und Fig. 2 gezeigten Ausführungsbeispiel sind die Fadenführer auskragend an dem Träger 11 befestigt. Die Fadenführer sind dabei bevorzugt aus einer Keramik hergestellt. Es ist jedoch auch möglich, stiftförmige Fadenführer mit metallischer Oberfläche einzusetzen.In Fig. 2 the thread guides 7 and 8 are shown in side view. The thread guides 7 and 8 each have an L-shaped thread guide edge 9. The L-shaped thread guide edge 9 provides a thread guide defined in its distances from the groove walls 3 and 4 and the groove base 5. A thread running plane 17 is spanned by the thread guide edges 9 of the thread guides 7 and 8 and is essentially parallel to the groove base 5. The threads 19.1 and 19.2 are thus guided through the heating groove 2 at one level. In the exemplary embodiment shown in FIGS. 1 and 2, the thread guides are attached to the carrier 11 in a projecting manner. The thread guides are preferably made of a ceramic. However, it is also possible to use pin-shaped thread guides with a metallic surface.
Die Anordnung der Fadenführer 7 und 8 ist bei diesem Ausführungsbeispiel derart gewählt, daß unterschiedliche Fadenlaufspuren 6.1 und 6.2 in der Heiznut ausgebildet sind. Eine derartige Heizeinrichtung wird bevorzugt zur Wärmebehandlung von Fäden verwendet, die anschließen zu einem Faden zusammengeführt und aufgewickelt werden.The arrangement of the thread guides 7 and 8 is selected in this embodiment such that different thread tracks 6.1 and 6.2 are formed in the heating groove. Such a heating device is preferably used for the heat treatment of threads, which are then brought together to form a thread and wound up.
Bei der Herstellung von texturierten Einzelfäden wird bevorzugt die in Fig. 3 und 4 gezeigte Anordnung der Fadenführer 7 und 8 verwendet.The arrangement of the thread guides 7 and 8 shown in FIGS. 3 and 4 is preferably used in the production of textured individual threads.
In Fig. 3 u und 4 ist ein weiteres Ausführungsbeispiel der erfindungsgemäßen Heizeinrichtung gezeigt. In Fig. 3 eine Teildraufsicht und in Fig. 4 ein Querschnitt des Ausführungsbeispiels gezeigt. Hierbei haben die Bauteile mit gleichen Funktionen identische Bezugszeichen erhalten. Die Heizeinrichtung ist in ihrem Grundaufbau identisch zu dem zuvor beschriebenen Ausführungsbeispiel, und es wird insoweit Bezug genommen zu der vorhergehenden Beschreibung. Bei der in Fig. 3 und Fig. 4 dargestellten Heizeinrichtung ist in der Heiznut 2 eine Profilschiene 14 als Träger eingelassen. Die Profilschiene 14 weist zwei in Längsrichtung des Heizers sich erstreckende Führungsnuten 15 und 16 auf, die jeweils durch Profilwände 12 und 13 begrenzt sind. Die Profilschiene 14 ist zur offenen Seite der Heiznut 2 ebenfalls offen. An den Nutwandungen 3 und 4 liegen die Profilwände 12 und 13 an. Die Führungsnuten 17 und 16 der Profilschiene 14 sind durch einen Mittelsteg 18 voneinander getrennt.3 u and 4 show a further embodiment of the heating device according to the invention. 3 shows a partial top view and FIG. 4 shows a cross section of the exemplary embodiment. Here, the components with the same functions have been given identical reference symbols. The basic construction of the heating device is identical to the previously described exemplary embodiment, and reference is made in this respect to the preceding description. In the heating device shown in FIGS. 3 and 4, a profiled rail 14 is embedded in the heating groove 2 as a carrier. The profile rail 14 has two guide grooves 15 and 16 which extend in the longitudinal direction of the heater and are each delimited by profile walls 12 and 13. The profile rail 14 is also open to the open side of the heating groove 2. The profile walls 12 and 13 rest on the groove walls 3 and 4. The guide grooves 17 and 16 of the profile rail 14 are separated from one another by a central web 18.
In der Führungsnut 17 der Profilschiene 14 sind die Fadenführer 7 mit Abstand in Längsrichtung hintereinander in einer Ebene angeordnet. Die Fadenleitkanten 9 benachbarter Fadenführer 7 sind gegenüberliegend versetzt zueinander angeordnet, so daß sich eine zick-zack-fόrmige Fadenlaufspur 6.1 in der Führungsnut 15 ausbildet.In the guide groove 17 of the profile rail 14, the thread guides 7 are arranged one behind the other in one plane in the longitudinal direction. The thread guide edges 9 of adjacent thread guides 7 are offset opposite one another arranged so that a zigzag-shaped thread running track 6.1 is formed in the guide groove 15.
In der Führungsnut 16 sind die Fadenführer 8 in einer Reihe versetzt zu den Fadenführern 7 angeordnet. Es ist jedoch auch möglich, die Fadenführer 8 symmetrisch zu dem Fadenführer 7 anzuordnen. Die Fadenführer 8 sind ebenfalls in Abstand abwechselnd mit ihren Fadenleitkanten 9 gegenüberliegend derart angeordnet, daß die Fadenlaufspur 6.2 zick-zack-förmig ist. Die Fadenführer 7 und 8 spannen somit eine Fadenlaufebene 17 auf, die durch die Fadenleitkanten 9 der Fadenführer 7 und 8 definiert ist. Die Fadenlaufebene 17 ist im wesentlichen parallel zum Nutgrund 5.In the guide groove 16, the thread guides 8 are arranged in a row offset from the thread guides 7. However, it is also possible to arrange the thread guides 8 symmetrically to the thread guide 7. The thread guides 8 are also arranged at a distance alternately with their thread guide edges 9 opposite one another in such a way that the thread running track 6.2 is zigzag-shaped. The thread guides 7 and 8 thus span a thread running plane 17 which is defined by the thread guide edges 9 of the thread guides 7 and 8. The thread running plane 17 is essentially parallel to the groove base 5.
Bei den gezeigten Fadenführern 7 und 8 ist die dem Faden zugewandte Oberfläche des Fadenführers abgerundet, damit der Faden beim Laufen über die Fadenleitkante 9 die Oberflächen derselben sanft überstreichen kann. Der Fadenführer ist L-förmig ausgebildet, so daß er eine Stiefelform besitzt. Die Stiefelform des Fadenführers 7 bzw. 8 ist durch einen Schaftbereich und einen Spannbereich gebildet. Zur Befestigung der Fadenführer ist es möglich, Aussparungen in der Profilschiene 14 vorzusehen, so daß die Fadenführer 7 oder 8 auswechselbar in der Profilschiene 14 einsteckbar sind.In the thread guides 7 and 8 shown, the surface of the thread guide facing the thread is rounded, so that the thread can gently sweep over the surfaces of the thread guide as it runs over the thread guide edge 9. The thread guide is L-shaped so that it has a boot shape. The boot shape of the thread guide 7 or 8 is formed by a shaft area and a tension area. To attach the thread guides, it is possible to provide recesses in the profile rail 14, so that the thread guides 7 or 8 can be inserted in the profile rail 14 in an exchangeable manner.
Bei den beschriebenen Ausführungsbeispielen läßt sich der Träger 11 bzw. die Profilschiene 14 beispielsweise zum Zwecke der Reinigung der Fadenführer auf einfache Weise aus der Heiznut 2 herausnehmen und wieder nach erfolgter Reinigung einsetzen.In the exemplary embodiments described, the carrier 11 or the profiled rail 14 can be removed from the heating groove 2 in a simple manner, for example for the purpose of cleaning the thread guides, and can be used again after cleaning.
In dem Ausführungsbeispiel zu Fig. 3 und 4 ist die Profilschiene 14 beispielhaft aus einem Teil hergestellt. Es besteht auch die Möglichkeit, die Profilschiene 14 durch zwei zusammengefügte U-förmige Einzelschienen zu bilden. Jede der Einzelschienen weist eine Führungsnut auf, in welcher die Fadenführer befestigt sind. Die Einzelschienen sind an ihren gegenüberliegenden Längsseiten miteinander verbunden. Auf eine Darstellung dieses Ausführungsbeispiels wurde verzichtet, da sich der Aufbau aus den Figuren 3 und 4 entnehmen läßt, wobei der Mittelsteg 18 aus den zusammengefügten Längsseiten der Einzelschienen gebildet wäre.In the exemplary embodiment of FIGS. 3 and 4, the profiled rail 14 is made, for example, from one part. There is also the possibility of forming the profile rail 14 by means of two joined U-shaped individual rails. Each of the individual rails has a guide groove in which the thread guides are fastened. The individual rails are on their opposite long sides connected with each other. An illustration of this exemplary embodiment has been dispensed with, since the structure can be seen from FIGS. 3 and 4, the central web 18 being formed from the joined longitudinal sides of the individual rails.
Beim Einsatz derartiger Heizeinrichtungen ist der Heizkörper 1 von einem Isoliermaterial umgeben. Auf der offenen Seite der Heiznut ist eine mit dem Heizkörper 1 und dem Isoliermaterial verbundener Deckel vorgesehen, so daß ein hoher Wärmeverlust vermieden wird. Diese Bauteile sind aufgrund der Übersichtlichkeit bei den gezeigten Ausführungsbeispielen nicht dargestellt und nicht näher beschrieben.When using such heating devices, the radiator 1 is surrounded by an insulating material. On the open side of the heating groove, a cover connected to the heating element 1 and the insulating material is provided, so that high heat loss is avoided. Because of the clarity, these components are not shown in the exemplary embodiments shown and are not described in detail.
Um parallel laufende Fäden unterschiedlich zu erwärmen, besteht auch die Möglichkeit, die Fadenführer 7 und 8 mit verschiedenen Fadenleitkanten 9 auszuführen, so daß eine zum Nutgrund 5 schräge Fadenlaufebene aufgespannt wird. Die Fäden könnten somit in verschiedenen Höhen durch die Heiznut geführt werden.In order to heat threads running in parallel differently, there is also the possibility of executing the thread guides 7 and 8 with different thread guide edges 9, so that a thread running plane inclined to the groove base 5 is spanned. The threads could thus be passed through the heating groove at different heights.
Die Anordnung der Fadenführer und die Ausbildung der Fadenlaufspuren in den zuvor beschriebenen Ausführungsbeispielen sind beispielhaft. Grundsätzlich ist jede beliebige Anordnung der Fadenführer innerhalb der Heiznut möglich, um symmetrische oder asymmetrische Fadenlaufspuren zu erhalten. Die Anzahl der Fadenlaufspuren ist ebenfalls nicht auf zwei beschränkt. So könnten auch mehr als zwei Fäden nebeneinander durch die Heiznut geführt werden. The arrangement of the thread guides and the formation of the thread running tracks in the exemplary embodiments described above are exemplary. In principle, any arrangement of the thread guides within the heating groove is possible in order to obtain symmetrical or asymmetrical thread running tracks. The number of thread running tracks is also not limited to two. In this way, more than two threads could also be passed through the heating groove side by side.
