In principle, the linear drive can be used to move the sliding element also by electrical, electro-mechanical or hydraulic means will be realized.

Das Einlegen des Fadens in die endgültige Heizlage erfolgt hierbei durch ein Verschwenken des Anlegefadenführers 6, indem der Anlegefadenführer 6 mit seinem Schwenkarm an einem kurvenförmigen Anschlag (hier nicht gezeigt) anschlägt und verschwenkt wird.The thread is inserted into the final heating position by a pivoting of the feed thread guide 6 by the feed thread guide 6 with its swivel arm on a curved stop (not here shown) strikes and is pivoted.

Die oberste Position entspricht der Position, in welcher das Steuerventil so lange Druckluft von einer Druckluftquelle zur Unterseite eines Magnetkolbens 7 (vgl. Fig. 4) zugeführt hat, bis dieser in der Hülse in seiner obersten Position im Anschlag mit dem Einlaßstopfen 24 oder in einem äußeren Anschlag ist. An der Führungsschiene 26 ist eine Bremseinrichtung 50 kurz unterhalb der Umlenkposition 3 angeordnet. Die Bremseinrichtung 50 befindet sich in einer Freilaufstellung, so daß das Gleitelement 14 frei an der Führungsschiene 26 verfahrbar ist.The top position corresponds to the position in which the control valve is so long compressed air from a compressed air source to the underside of a magnetic piston 7 (see FIG. 4) until it is in the sleeve in its uppermost position in the stop with the inlet plug 24 or in one outer stop is. There is a braking device on the guide rail 26 50 arranged just below the deflection position 3. The braking device 50 is in a free-running position, so that the sliding element 14 can be moved freely on the guide rail 26.

In Fig. 2 ist ein Schaltbild einer prinzipiellen Anordnung eines Ausführungsbeispiels der Erfindung ohne Bremseinrichtung gezeigt. Eine Druckluftquelle 1 ist über ein Steuerventil 2 mit einem Linearantrieb 5 verbunden. Der Linearantrieb 5 weist eine Hülse auf, in welcher kolbenstangenlos durch Druckbeaufschlagung ein Magnetkolben auf- und abbewegt werden kann. An der Außenseite der Hülse ist ein Gleitelement 14 als Magnet gleitend befestigt, welcher eine Polung aufweist, die verschieden ist von der des Magnetkolbens im Inneren der Hülse. Dadurch wird der am Außenumfang der Hülse befestigte Magnet bzw. das Gleitelement 14 bei Druckbeaufschlagung des Magnetkolbens im Inneren der Hülse auf- und abbewegt. Am Gleitelement 14 ist der Anlegefadenführer 6 angeordnet, mittels welchem der Faden in die Heizeinrichtung 8 bzw. Kühleinrichtung 9 eingelegt werden kann. Das Steuerventil 2 wird von einer Bedienperson manuell geschaltet. Darüber hinaus ist das Steuerventil 2 über eine Steuereinrichtung 70 ansteuerbar. Die Steuereinrichtung 70 dient dazu, bei Ausfall der elektrischen Energie der Texturiermaschine die Druckluftquelle 1 mit dem Linearantrieb 5 derart zu verbinden, daß zunächst der Kolben in einer durch die Steuereinrichtung 70 vorgegebenen Impulszeit abwärts bewegt wird, um anschließend in einer Parkstelung bei mittlerer Position des Steuerventils 2 zu verharren. Die Druckluftversorgung wird hierbei über einen Druckspeicher 72 sichergestellt. 2 is a circuit diagram of a basic arrangement of an embodiment shown the invention without braking device. A Compressed air source 1 is via a control valve 2 with a linear drive 5 connected. The linear drive 5 has a sleeve in which rodless a magnetic piston is moved up and down by applying pressure can be. On the outside of the sleeve is a sliding element 14 slidably attached as a magnet, which has a polarity that is different is that of the magnetic piston inside the sleeve. Thereby becomes the magnet attached to the outer circumference of the sleeve or the sliding element 14 when pressure is applied to the magnetic piston inside the Sleeve moved up and down. The thread guide 6 is on the sliding element 14 arranged by means of which the thread in the heating device 8 or Cooling device 9 can be inserted. The control valve 2 is from switched manually by an operator. In addition, the control valve 2 controllable via a control device 70. The controller 70 is used in the event of failure of the electrical energy of the texturing machine To connect compressed air source 1 with the linear drive 5 such that first the piston in a predetermined by the control device 70 Pulse time is moved down to then in a parking position to remain in the middle position of the control valve 2. The compressed air supply is ensured here via a pressure accumulator 72.

In Fig. 3 ist der Linearantrieb 5 aus Fig. 2 gezeigt, wobei die Ansteuerung des Linearantriebes mit einem Steuerventil 2.1 erfolgt. Gegenüber der Ausführung aus Fig. 2 wird hierbei das Steuerventil 2.1 bei Stromausfall mit einem Vorsteuerventil 73 angesteuert. Hierzu wird das Vorsteuerventil 73 über die Steuereinrichtung 70 aktiviert. Gleichzeitig wird bei Umschaltung des Vorsteuerventils 73 die Bremseinrichtung 50 aktiviert, so daß ein Sperrglied 52 in die Laufbahn des Gleitelementes 14 eingreift. Das Steuerventil 2.1 wird durch die Ansteuerung durch das Vorsteuerventil 73 in seine rechte Schaltstellung gebracht, so daß der Magnetkolben des Linearantriebes 5 derart beaufschlagt wird, daß das Gleitelement 14 sich abwärts bewegt. Durch die Aktivierung der Bremseinrichtung 50 wird das Gleitelement 14 jedoch in einer vorgegebenen Parkstellung festgehalten.3 shows the linear drive 5 from FIG. 2, with the control of the linear drive with a control valve 2.1. Across from 2, the control valve 2.1 is used here Power failure controlled with a pilot valve 73. For this, the Pilot valve 73 activated via the control device 70. simultaneously when the pilot valve 73 is switched over, the braking device 50 activated so that a locking member 52 in the raceway of the sliding element 14th intervenes. The control valve 2.1 is controlled by the Pilot valve 73 brought into its right switching position, so that the Magnetic piston of the linear drive 5 is acted on such that the Sliding element 14 moves downwards. By activating the braking device 50, however, the sliding element 14 is in a predetermined Park position held.

Fig. 4 zeigt den Linearantrieb 5 des Anlegefadenführers mit einer Bremseinrichtung 50. An dem Steuerventil 2 ist eine Druckluftquelle 1 vorgesehen, über welche Druckluft dem Steuerventil zugeführt wird. Von diesem Steuerventil wird je nach Stellung eines gebildeten Doppelkolbens 15 eine Zuleitung zur Unterseite eines kolbenstangenlosen Magnetkolbens 7 bzw. zur Oberseite dieses Magnetkolbens 7 geführt, welcher in einer zylindrisch ausgebildeten Führungsschiene (Hülse) 26 geführt ist. In entgegengesetzter Polung zur Polung des Magneten des Magnetkolbens 7 befindet sich gleitbar am Außenumfang der Hülse 26 ein Gleitelement 14 mit Magneten, an welchem der eigentliche Anlegefadenführer 6 mit Umlenkrolle 36 schwenkbar angebracht ist. Der Magnetkolben 7 weist mehrere parallel zueinander angeordnete Ringmagnete 29 auf. Demgegenüber sind am Außenmantel die Ringmagnete 28 im Gleitelement 14 angeordnet. Im Ventil 2 ist ein Druckluftanschluß 20 für die Verbindung der Druckluftquelle 1 mit dem Steuerventil, ein Druckluftanschluß 21 für die Verbindung des Steuerventils 2 mit der Oberseite des Magnetkolbens 7 über einen Druckluftanschlußstutzen 24 an der Oberseite der Hülse 26 zur Beaufschlagung der Oberseite des Magnetkolbens, ein Druckluftanschluß 22 zur Beaufschlagung des Magnetkolbens 7 von der Unterseite her sowie ein Druckluftanschluß 23 zum automatischen Einfahren des Fadenführers, d.h. zum Entfernen des Fadens aus der Heizeinrichtung 8 bzw. der Kühleinrichtung 9, vorgesehen. Der Doppelkolben 15 des Steuerventils 2 weist desweiteren einen Stößel 16 mit Stößelgriff auf. Zwischen dem Doppelkolben 15 und dem Stößelgriff sind im Stößel 3 Rastnuten 17 eingearbeitet, welche den jeweiligen Raststellungen des Fadenführers 6 entsprechen. Im Gehäuse des Steuerventils 2 befindet sich eine mit einer Feder 19 beaufschlagte Kugel 18, welche in eine der jeweiligen Raststellung entsprechende Rastnut 17 eingreift und so diese jeweilige Raststellung arretiert. Die in Fig. 4 dargestellte erste Raststellung entspricht der Stellung, bei welcher die Druckluft von der Druckluftquelle 1 über den Druckluftanschluß 20 und den Druckluftanschluß 22 die Unterseite des Magnetkolbens 7 beaufschlagt, wodurch dieser ausgefahren wird, d.h. von unten nach oben bewegt wird. Der Druckluftanschluß 21 ist mit dem Entlüftungskanal 30 des Doppelkolbens verbunden, so daß die Oberseite des Magnetkolbens 7 entlastet ist. Bleibt die Druckluftzufuhr lang genug bestehen, wird der Magnetkolben 7 bis zu einem Anschlag nach oben bewegt. Wegen der unterschiedlichen Polung der Ringmagneten des Magnetkolbens 7 im Innern der Hülse 26 und des an deren Außenseite gleitenden Ringmagneten 28 wird somit der Anlegefadenführer 6 synchron zur Bewegung des Magnetkolbens 7 bewegt.Fig. 4 shows the linear drive 5 of the thread guide with a braking device 50. A compressed air source 1 is provided on the control valve 2, via which compressed air is fed to the control valve. Of This control valve is depending on the position of a double piston formed 15 a feed line to the underside of a rodless magnetic piston 7 or to the top of this magnetic piston 7, which in a cylindrical guide rail (sleeve) 26 is guided. In opposite polarity to the polarity of the magnet of the magnetic piston 7 there is a sliding element 14 slidably on the outer circumference of the sleeve 26 with magnets on which the actual thread guide 6 with Deflection roller 36 is pivotally attached. The magnetic piston 7 has a plurality of ring magnets 29 arranged parallel to one another. In contrast, are the ring magnets 28 in the sliding element 14 on the outer casing arranged. In valve 2 is a compressed air connection 20 for the connection the compressed air source 1 with the control valve, a compressed air connection 21 for the connection of the control valve 2 with the upper side of the magnetic piston 7 via a compressed air connection piece 24 on the top of the sleeve 26 for Actuation of the top of the magnetic piston, a compressed air connection 22 to act on the magnetic piston 7 from the bottom and a Compressed air connection 23 for automatic retraction of the thread guide, i.e. for removing the thread from the heating device 8 or the cooling device 9, provided. The double piston 15 of the control valve 2 has furthermore a plunger 16 with a plunger handle. Between the double piston 15 and the plunger handle 3 locking grooves 17 are incorporated in the plunger, which correspond to the respective locking positions of the thread guide 6. in the The housing of the control valve 2 is one with a spring 19 acted upon ball 18, which in one of the respective locking position Appropriate locking groove 17 engages and so this respective locking position locked. The first latching position shown in FIG. 4 corresponds to the Position in which the compressed air from the compressed air source 1 via the Compressed air connection 20 and the compressed air connection 22 the underside of the Magnetic piston 7 is applied, whereby it is extended, i.e. of is moved upwards. The compressed air connection 21 is with the Vent channel 30 of the double piston connected so that the top of the magnetic piston 7 is relieved. The compressed air supply stays long enough exist, the magnetic piston 7 up to a stop emotional. Because of the different polarity of the ring magnets of the magnetic piston 7 inside the sleeve 26 and on the outside sliding ring magnet 28, the thread guide 6 is thus synchronous moved to move the magnetic piston 7.

Durch Betätigung des Stößels 16 sind eine zweite und eine dritte Raststellung einstellbar. In der zweiten Raststellung wird der Kolben von der Oberseite und Unterseite mit Druckluft beaufschlagt, so daß der Anlegefadenführer 6 in der monentanen Stellung verharrt. Die dritte Raststellung des Stößels bewirkt, daß der Magnetkolben 7 abwärts bewegt wird und somit das Gleitelement 14 mit dem Anlegefadenführer 6 abwärts an der Hülse verfahren wird.By actuating the plunger 16, a second and a third locking position adjustable. In the second locking position, the piston is removed from the Compressed air is applied to the top and bottom so that the thread guide 6 remains in the monthly position. The third rest position of the plunger causes the magnetic piston 7 to move downward thus the sliding element 14 with the thread guide 6 down on the Sleeve is moved.

Die Hülse 26 ist mit einem Träger 51 verbunden. An dem Träger 51 ist eine Bremseinrichtung 50 befestigt. Die Bremseinrichtung 50 besteht aus einer Klinke 52, die an ihrem einen Ende schwenkbar in einem Drehgelenk 53 mit dem Träger 51 verbunden ist. Die Klinke 52 wird mittels einer Feder 55 in der in Fig. 4 gezeigten Stellung (Freilaufstellung) gehalten. Die Feder 55 ist hierzu zwischen dem Träger 51 und der Klinke 52 angeordnet. Die Klinke 52 ist in Bewegungsrichtung 54 schwenkbar. Des weiteren weist die Bremseinrichtung eine Zylinderkolbeneinheit 57 auf. Die Zylinderkolbeneinheit ist über einen Druckanschluß 60 mit einem Druckmedium, bevorzugt Druckluft, beaufschlagbar. Der Kolben 58 weist einen Kolbenschaft 58.1 auf, der in dem Zylinder geführt ist. An dem Kolbenschaft 58.1 ist die Kolbenstange 58.2 befestigt. Die Kolbenstange 58.2, die aus dem Zylinder heraustritt, weist auf dem gegenüberliegenden Ende eine Kolbenkappe 58.3 auf. Zwischen der Kolbenstange 58.1 und der Kolbenkappe 58.3 ist ein Hinterschnitt 64 gebildet. Die Kolbenkappe 58.3 ist konisch mit dem Konus 62 ausgeführt. Der Konus 62 ist dabei derart gestaltet, daß er bei Ausfahrt des Kolbens, d.h. bei Druckbelastung des Kolbens mit einer Anschrägung 63 an der Klinke 52 entlang gleitet. Zwischen dem Kolbenschaft 58.1 und dem Zylinder ist im Zwischenraum zur Kolbenstange 58.2 eine Feder 61 angeordnet, so daß der Kolben gegen die Kraftrichtung der Feder 61 ausfahren muß. Die Zylinderkolbeneinheit 57 ist mit einem Steuergerät 4 verbunden. Das Steuergerät 4 ist des weiteren mit Druckquelle 1 sowie mit dem Steuerventil 2 über den Druckanschluß 23 verbunden. Das Steuergerät 4 weist - wie in Fig. 3 dargestellt - das Vorsteuerventil 73 und die Steuereinrichtung 70 auf. The sleeve 26 is connected to a carrier 51. On the support 51 is a braking device 50 is attached. The braking device 50 consists of a pawl 52 which is pivotable at one end in a swivel joint 53 is connected to the carrier 51. The pawl 52 is by means of a spring 55 in the position shown in FIG. 4 (freewheel position) held. The spring 55 is for this purpose between the carrier 51 and the Pawl 52 arranged. The pawl 52 is in the direction of movement 54 pivotable. Furthermore, the braking device has a cylinder-piston unit 57 on. The cylinder-piston unit is via a pressure connection 60 can be acted upon with a pressure medium, preferably compressed air. The Piston 58 has a piston shaft 58.1, which is in the cylinder is led. The piston rod 58.2 is attached to the piston shaft 58.1. The piston rod 58.2, which emerges from the cylinder, points to the opposite end a piston cap 58.3. Between the Piston rod 58.1 and piston cap 58.3 is an undercut 64 educated. The piston cap 58.3 is conical with the cone 62. The cone 62 is designed in such a way that when the piston extends, i.e. with pressure loading of the piston with a bevel 63 on the Pawl 52 slides along. Between the piston skirt 58.1 and the In the space between the piston rod 58.2, the cylinder is a spring 61 arranged so that the piston against the direction of force of the spring 61st must extend. The cylinder piston unit 57 is connected to a control unit 4 connected. The control unit 4 is also with pressure source 1 and connected to the control valve 2 via the pressure connection 23. The Control device 4, as shown in FIG. 3, has pilot valve 73 and the control device 70.

Im folgenden wird nun die Betriebsweise der Bremseinrichtung beschrieben.The operation of the braking device will now be described.

Hierzu dienen die Darstellungen in Fig. 4 bis 6.The illustrations in FIGS. 4 to 6 serve for this purpose.

In Fig. 4 ist die Situation dargestellt, in der die Bremseinrichtung nicht aktiviert ist. Die Klinke 52 wird mittels der Feder 55 in ihrer Freilaufstellung gehalten. Das Gleitelement 14 mit dem Anlegefadenführer 6 kann ungehindert an der Führungsschiene 26 bewegt werden. Im Falle, daß die Texturiermaschine aufgrund einer Energiestörung ausfällt, oder der Faden in der Texturiermaschine zum Stillstand kommt, wird mittels dem Steuergerät 4 ein Steuerimpuls ausgelöst. Aufgrund des Steuerimpulses wird die Zylinder-Kolben-Einheit 57 kurzzeitig mit Druckluft von der Druckluftquelle beaufschlagt. Hierbei bewegt sich der Kolben 58 in Bewegungsrichtung 68 (s. Fig. 5). Während der Ausfahrbewegung des Kolbens stoßen der Konus 62 und die Anschrägung 63 gegeneinander, so daß bei fortschreitender Bewegung des Kolbens 58 die Klinke 52 in Schwenkrichtung 69 verschwenkt wird. Der Kolben 58 fährt so weit aus, bis die Eindrehung 65 der Klinke in den Hinterschnitt 64 des Kolbens einrastet. Die Klinke 52 befindet sich nun in einer Wartestellung, wobei sie mit ihrem Anschlag 66 in die Laufbahn des Gleitelementes 14 hineinragt.4 shows the situation in which the braking device is not is activated. The pawl 52 is in its free-running position by means of the spring 55 held. The sliding element 14 with the thread guide 6 can can be moved freely on the guide rail 26. In the event that the Texturing machine fails due to an energy disturbance, or the thread in the texturing machine comes to a standstill using the control unit 4 triggered a control pulse. Due to the control impulse, the Cylinder-piston unit 57 briefly with compressed air from the compressed air source applied. Here, the piston 58 moves in the direction of movement 68 (see Fig. 5). During the extension movement of the piston, the Cone 62 and the chamfer 63 against each other, so that as it progresses Movement of the piston 58 and the pawl 52 in the pivoting direction 69 is pivoted. The piston 58 extends until the indentation 65 the pawl engages in the undercut 64 of the piston. The handle 52 is now in a waiting position, with its stop 66 protrudes into the track of the sliding element 14.

Wie in Fig. 4 dargestellt, ist das Steuergerät 4 mit dem Druckanschluß 23 des Steuerventils 2 verbunden. Bei Stromausfall verbindet das Steuergerät 4 den Druckanschluß 23 ebenfalls mit der Druckquelle 1. Dadurch wird erreicht, daß der Doppelkolben 15 in die Schaltstellung verschoben wird, die ein Abwärtsfahren des Gleitelementes 14 bewirkt.
Das Gleitelement 14 trifft mit seiner Anschlagfläche 67 auf den Anschlag 66 der Klinke 52. Beim Zusammentreffen des Gleitelementes 14 mit der Klinke 52 wird die Klinke 52 aufgrund der Abwärtsbewegung des Gleitelementes 14 weiter in Schwenkrichtung 69 verschoben bis die an dem Anschlag 66 angebrachte Schulter 71 der Klinke 52 an das Gleitelement 14 anstößt. In dieser Stellung (Parkstellung) - wie in Fig. 6 gezeigt - kommt das Gleitelement 14 zum Stillstand. Gleichzeitig wird durch das Weiterverschwenken der Klinke 52 in Richtung 69 die Eindrehung 65 aus dem Eingriffbereich des Hinterschnitts 64 des Kolben 58 geschwenkt. Damit wird die Raststellung des Kolbens 58 freigegeben und der Kolben 58 wird durch die Feder 61 in seine Ausgangsstellung zurückbewegt in Richtung 68.
As shown in Fig. 4, the control device 4 is connected to the pressure port 23 of the control valve 2. In the event of a power failure, the control device 4 also connects the pressure connection 23 to the pressure source 1. This ensures that the double piston 15 is moved into the switching position which causes the sliding element 14 to move downward.
The sliding element 14 strikes the stop 66 of the pawl 52 with its stop face 67. When the sliding element 14 meets the pawl 52, the pawl 52 is displaced further in the pivoting direction 69 due to the downward movement of the sliding element 14 until the shoulder 71 attached to the stop 66 Pawl 52 abuts the sliding element 14. In this position (parking position) - as shown in Fig. 6 - the sliding element 14 comes to a standstill. At the same time, by pivoting the pawl 52 further in the direction 69, the recess 65 is pivoted out of the engagement area of the undercut 64 of the piston 58. The locking position of the piston 58 is thus released and the piston 58 is moved back into its starting position in the direction 68 by the spring 61.

Wird die Maschine wieder in Betrieb genommen bzw. ist die Energieversorgung wieder hergestellt, wird der Magnetkolben 7 durch Ansteuerung des Steuerventils 2 in Anlegeposition bewegt und bewegt das Gleitelement 14 wieder aus der Parkstellung. Sobald das Gleitelement 14 aus dem Anschlag 66 verschoben wird, wird die Klinke 52 mittels der Feder 55 in ihre Ausgangsstellung (Freilaufstellung) zurückgeschwenkt. Somit ist das Gleitelement an der Führungsschiene 26 wiederum frei beweglich.Is the machine put back into operation or is the energy supply restored, the magnetic piston 7 is activated by control of the control valve 2 in the applied position moves and moves the sliding member 14 again from the park position. As soon as the sliding element 14 from the Stop 66 is moved, the pawl 52 by means of the spring 55 in their starting position (freewheeling position) pivoted back. So that's it Sliding element on the guide rail 26 in turn freely movable.

Die Bremseinrichtung wird gemeinsam mit dem Linearantrieb des Anlegefadenführers bevorzugt bei Energiestörungen der Texturiermaschine aktiviert. Es ist jedoch auch möglich, die Bremseinrichtung bei Wartungsarbeiten an der Maschine zu betätigen, so daß der stillstehende Faden schnellstmöglich aus dem Heizer geholt werden kann. Sobald das Gleitelement bei Wartungsarbeiten an der Bremseinrichtung anliegt, kann der Linearantrieb des Anlegefadenführers ausgestellt werden. Hierbei ist von Vorteil, wenn die Betätigung der Heizklappe eines Heizers mit der Bewegung des Gleitelementes gesteuert wird. In Fig. 7 ist ein Ausführungsbeispiel hierzu gezeigt, bei dem der Anlegefadenführer mit seinem Gleitelement 14 an einem oberen Anschlag anliegt. The braking device is used together with the linear drive of the thread guide preferably activated in the event of energy disturbances in the texturing machine. However, it is also possible to use the braking device during maintenance work to operate on the machine so that the stationary thread can be taken out of the heater as soon as possible. Once the sliding element is present during maintenance work on the braking device Linear drive of the feed thread guide are issued. Here is from Advantage if the operation of the heater flap with the Movement of the sliding element is controlled. 7 is an embodiment shown here, in which the thread guide with his Sliding element 14 abuts an upper stop.

Der Anschlag wird hierbei durch einen Kontaktschalter 38 gebildet. Der Kontaktschalter 38 ist mit einer Steuereinrichtung 37 verbunden. Die Steuereinrichtung 37 besteht aus einem Steuerventil 39 und einem Schließzylinder 40. In der gezeigten Stellung wird das Steuerventil 39 mittels dem Kontaktschalter 38 in seine linke Schaltstellung verschoben. Der Kontaktschalter 38 erhält hierbei seinen Schaltimpuls von dem Gleitelement 14. In der linken Schaltstellung des Steuerventils 39, das als 3/2-Wege-Ventil ausgeführt ist, wird die Druckluftquelle 1 mit dem Druckraum 41 des Schließzylinders 40 verbunden. Der Schließzylinder 40 ist mittels seiner Kolbenstange 42 mit der Heizklappe 44 der Heizeinrichtung 8 verbunden. Bei Druckbeaufschlagung des Druckraumes 41 fährt der Kolben aus und schließt somit die Heizklappe 44. Bei der gezeigten Ausführung weist die Heizeinrichtung 8 zwei Heizkanäle 43.1 und 43.2 auf. In jedem Heizkanal wird ein Faden 10 geführt. Die Steuereinrichtung 37 weist in diesem Fall zwei Steuerventile 39 auf, die jeweils von einem Kontaktschalter angesteuert werden. Jeder Kontaktschalter 38 bildet den Anschlag für den jeweiligen Fadenanleger der Fäden 10.1 und 10.2. Bei dieser Anordnung wird die Heizklappe 44 nur in dem Fall geschlossen, das beide Fadenführer bzw. Gleitelemente 14.1 und 14.2 in ihrem Anschlag liegen. Sobald sich ein Gleitelement 14 bzw. Fadenführer vom Anschlag entfernt, wird das Steuerventil in seine rechte Schaltstellung geschaltet. In dieser Schaltstellung wird der Druckraum 41 des Schließzylinders 40 entlüftet, so daß die Heizklappe 41 der Heizeinrichtung 8 geöffnet wird bzw. geöffnet bleibt. Somit kann der Faden entnommen werden. The stop is formed by a contact switch 38. The Contact switch 38 is connected to a control device 37. The Control device 37 consists of a control valve 39 and a lock cylinder 40. In the position shown, the control valve 39 is by means of the contact switch 38 moved to its left switching position. The Contact switch 38 receives its switching pulse from the sliding element 14. In the left switch position of the control valve 39, which acts as a 3/2-way valve is carried out, the compressed air source 1 with the pressure chamber 41st of the lock cylinder 40 connected. The locking cylinder 40 is by means of its piston rod 42 is connected to the heating flap 44 of the heating device 8. When the pressure chamber 41 is pressurized, the piston moves and thus closes the heating flap 44. In the embodiment shown the heating device 8 has two heating channels 43.1 and 43.2. In each A heating thread 10 is guided. The control device 37 points in In this case, two control valves 39, each by a contact switch can be controlled. Each contact switch 38 forms the stop for the respective thread feeder of threads 10.1 and 10.2. At this The heater flap 44 is closed only in the event that both thread guides or sliding elements 14.1 and 14.2 in their stop lie. As soon as a sliding element 14 or thread guide is off the stop removed, the control valve is switched to its right switch position. In this switching position becomes the pressure chamber 41 of the locking cylinder 40 vented so that the heating flap 41 of the heating device 8 is opened or remains open. The thread can thus be removed.
