Description

Die Erfindung betrifft eine Vorrichtung zum Uebergeben eines Fadenfeldes von einem Fadenwickel auf einen Wickelbaum gemäss dem Oberbegriff von Anspruch 1. Mit derartigen Vorrichtungen werden namentlich für die Webereivorbereitung die Kettbäume in der vollen Breite der späteren webkette gewickelt. Beim Fadenwickel, von dem das Fadenfeld abgezogen wird, kann es sich um den Schärwickel in einer Schärmaschine handeln. Alternativ könnten aber auch Zettelbäume abgewickelt werden. Vor dem Aufwickeln des Fadenfeldes auf den Wickelbaum könnte das Fadenfeld ausserdem noch ein Behandlungsmodul wie z.B. eine Wachsvorrichtung durchlaufen.The invention relates to a device for transferring a Thread field of a thread winding on a winding tree according to the preamble of claim 1. With such devices become especially for the weaving preparation the warp beams in the full width of the later Wrapped web. When filament winding from which the thread field is deducted, it may be the Schärwickel in one Act as a warping machine. Alternatively, but could also Zettelbäume be handled. Before winding up the thread field on the winding tree, the thread field could also still one Treatment module, such as go through a waxing device.

Durch die EP-A-391 129 ist eine Vorrichtung zum Umbäumen von Schärketten bekannt geworden, bei der oberhalb der Schärtrommel und des Wickelbaums eine motorisch antreibbare Fördereinrichtung für eine daran während des Umlegens der Schärkette anzubringende Schärkettenklemmstange angeordnet ist. Die Fördereinrichtung besteht aus zwei parallel zueinander und zu den Schärkettenfäden angeordneten, endlos umlaufenden Transportbändern mit daran vorgesehenen Einhängehaken für die dazwischen mit ihren Enden anzuhängende Schärkettenklemmstange. Das Fadenfeld wird bei der Uebergabe allerdings über die Sohlenlinie der Schärtrommel abgewickelt und erreicht über höher gelegene Umlenkwalzen den Webkettbaum. Die kontinuierliche Aufrechterhaltung einer Fadenspannung ist dabei nicht möglich, weil die Schärkettenklemmstange zum Einhängen in die Einhängehaken zuerst manuell unter der Sohlenlinie hindurchgeführt und dann angehoben werden muss. Dabei kann sich das Fadenfeld beim Uebergabevorgang lockern, was später zu ungleichmässigen Webketten führt.By EP-A-391 129 is a device for rebuilding of Schärketten become known at the above the warping drum and the winding tree a motor driven conveyor for one during the folding of the warp chain to be attached Schärkettenklemmstange is arranged. The conveyor consists of two parallel to each other and arranged to the warp strings, endlessly circulating Conveyor belts with attached hooks for the between them with their ends to be attached Schärkettenklemmstange. The thread field is on the transfer, however, over unwound and reached the sole line of the warping drum over higher deflection rollers the warp beam. The continuous Maintaining a thread tension is included not possible because the Schärkettenklemmstange for hanging in the hooks first manually under the sole line must be passed through and then raised. It can the thread field loosen during the transfer process, what later leads to uneven web chains.

Mit der bekannten Vorrichtung gemäss Stand der Technik ist es ausserdem nicht möglich, die vorhandenen Umlenkwalzen zwischen Schärtrommel und Kettbaum zu umfahren. Auch ein Behandlungsmodul zum Beaufschlagen des Fadenfeldes mit einer Behandlungsflüssigkeit kann nicht integriert werden.It is with the known device according to the prior art also not possible, the existing guide rollers between To avoid the warping drum and warp beam. Also a treatment module for applying the thread field with a treatment liquid can not be integrated.

Es ist daher eine Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art zu schaffen, um die Uebergabe des Fadenfeldes zu vereinfachen und zu beschleunigen und um eine homogene Qualität des Fadenfeldes bei der Uebergabe zu gewährleisten. Ausserdem soll die Vorrichtung vielseitig anwendbar sein und wahlweise auch die Integration von Umlenkwalzen oder Behandlungsmodulen beim späteren Bäumprozess ermöglichen. Diese Aufgabe wird mit einer Vorrichtung mit den Merkmalen von Anspruch 1 gelöst.It is therefore an object of the invention to provide a device of to create the transfer of the aforementioned type To simplify and accelerate thread field and one ensure homogeneous quality of the thread field during transfer. In addition, the device should be versatile and optionally also the integration of guide rollers or treatment modules in the later tree process enable. This task will with a device having the features of claim 1 solved.

Konstruktive Vorteile können erreicht werden, weil die Umlaufrichtung der Transportketten reversibel ist und weil die Anhängestange sowohl an einem unteren Kettentrum, als auch an einem oberen Kettentrum zum Wickelbaum transportierbar ist. Auf diese Weise lassen sich mit ein und derselben Uebergabevorrichtung je nach Bewegungsrichtung der Transportketten zwei verschiedene Führungsbahnen zurücklegen. Dies kann beispielsweise dazu eingesetzt werden, dass zwischen den beiden Kettentrums eine Umlenkwalze oder ein Behandlungsmodul für das Fadenfeld derart angeordnet wird, dass die Umlenkwalze bzw. das Behandlungsmodul mit der Anhängestange am unteren Kettentrum unterfahren und am oberen Kettentrum überfahren werden kann. Besteht das Behandlungsmodul beispielsweise aus einer Schlichtewalze, so kann das Fadenfeld wahlweise über die Schlichtewalze oder unter Umgehung der Schlichtewalze gestreckt auf den Wickelbaum geführt werden. In beiden Fällen sind keine besonderen Vorkehrungen erforderlich und das Fadenfeld bleibt gespannt, gleichgültig über welche Führungsbahn es den Wickelbaum erreicht.Design advantages can be achieved because the direction of rotation the transport chains is reversible and because the Hitch rod both at a lower chain center, as well as at an upper chain center to the winding tree is transportable. In this way can be with one and the same transfer device depending on the direction of movement of the transport chains cover two different guideways. This can For example, be used between the both chain centers a deflection roller or a treatment module is arranged for the thread field such that the deflection roller or the treatment module with the trailer rod at the bottom Drive under the chain and drive over at the top of the chain can be. For example, if the treatment module fails a sizing roll, the thread field can optionally over the sizing roll or bypassing the sizing roll stretched out on the winding tree. In both cases No special precautions are needed and that Thread field remains taut, regardless of which guideway it reaches the winding tree.

Die Uebergabeeinrichtung ist vorteilhaft so ausgestaltet, dass sie die Wickelvorrichtung und den Wickelbaum übergreift. Die freie Distanz zwischen der Peripherie des Fadenwickels und der Anhängestange in der Ausgangsstellung einerseits und dem Wickelbaum und der Anhängestange in der Uebergabestellung andererseits sollte dabei so kurz wie möglich sein. Besonders vorteilhaft weisen dabei die Transportketten wenigstens einen Kettenabschnitt auf, der auf der vom Wickelbaum abgewandten Seite der Wickelmaschine zwischen der Ebene der Drehachse der Wickelmaschine und der Ebene der Scheitellinie des vollen Wickels verläuft. Die Transportkette kann auf diese Weise über einen Umfangswinkel von bis zu 45° oder mehr von oben über den Fadenwickel gegen unten geführt sein. Die Anhängestange ist dabei in der Ausgangsposition dem Auflaufpunkt der einzelnen Fäden beim Erstellen des Fadenwickels stark angenähert. Eine Lockerung des Fadenfeldes wird unabhängig von der Umlaufrichtung der Transportketten auch deshalb vermieden, weil das Fadenfeld über die Scheitellinie des Wickels abwickelbar ist. Dadurch muss die Anhängestange nicht unter der Sohlenlinie hindurchgeführt werden, bevor sie an den Ketten eingehängt werden kann.The transfer device is advantageously configured in such a way that that it overlaps the winding device and the winding tree. The free distance between the periphery of the filament winding and the trailer rod in the starting position on the one hand and the winding tree and the trailer rod in the transfer position On the other hand, it should be as short as possible. Especially Advantageously, the transport chains have at least one Chain section on the side facing away from the winding tree Side of the winding machine between the plane of rotation of the Wrapping machine and the level of the crest line of the full Wickels runs. The transport chain can do this way over a circumferential angle of up to 45 ° or more from above be guided over the thread winding against the bottom. The trailer rod is in the starting position the casserole of the strongly approximated individual threads when creating the thread winding. A relaxation of the thread field is independent of the circulation direction of the transport chains also avoided therefore because the thread field over the apex line of the roll is developable. As a result, the hitch must not under the sole line are passed before they to the Chains can be hung.

Die Synchronisation der Transportketten erfolgt vorteilhaft über eine Getriebewelle zwischen den beiden äussersten Umlenkrädern einer Transportkette, vorzugsweise in einem mittigen Bereich der Transportketten. Die Getriebewelle tritt damit an den Enden des Zugmittelgetriebes nicht störend in Erscheinung, wie dies bei der Vorrichtung gemäss EP-A-391 129 der Fall ist.The synchronization of the transport chains is advantageous via a gear shaft between the two outermost deflection wheels a transport chain, preferably in a central Range of transport chains. The transmission shaft occurs so that at the ends of the traction mechanism not disturbing in Appearance, as in the device according to EP-A-391 129 the case is.

Die mit einer Uebergabeeinrichtung bewegte Anhängestange gewährleistet ein völlig gleichmässiges Abziehen des Fadenfeldes in der Uebergabephase, bis das Fadenfeld am Wickelbaum befestigt ist. Da stets eine Fadenspannung aufrechterhalten wird, besteht nicht die Gefahr, dass das Fadenfeld ungeordnet auseinanderfällt. Das Fadenfeld wird über die Scheitellinie des Fadenwickels abgewickelt, was allerdings voraussetzt, dass der Fadenwickel vorgängig gemäss der Lehre der EP-A-517 655 über die Fusslinie aufgewickelt wurde. Beim Abziehen des Fadenfeldes für den Uebergabevorgang über die Scheitellinie des Fadenwickels kann die Anhängestange derart angesetzt werden, dass keine Lockerung des Fadenfeldes eintritt.The trailer rod moved by means of a transfer device ensures a completely uniform removal of the thread field in the transfer phase, until the thread field on the winding tree is attached. As always a thread tension maintained There is no risk that the thread field is disordered falling apart. The thread field is over the crest line the thread winding unwound, which, however, requires that the thread winding previously according to the teaching of EP-A-517 655 was wound over the foot line. When peeling off the thread field for the transfer over the crest line the thread winding, the trailer rod can be recognized be that no loosening of the thread field occurs.

Der Fadenwickel wird dabei wenigstens während der uebergabe des Fadenfeldes mit einer Bremskraft beaufschlagt. Damit kann beim Verschieben der Anhängestange eine angenähert konstante Fadenspannung eingehalten werden. Eine Bremseinrichtung wie z.B. eine Trommelbremse ist normalerweise an der Wickelvorrichtung ohnehin vorhanden.The filament winding is doing at least during the transfer of the thread field acted upon by a braking force. So that can when moving the trailer rod an approximately constant Thread tension are maintained. A braking device like e.g. a drum brake is usually on the winding device anyway available.

Die endlosen Transportketten können auch über komplizierte Kurvenbahnen gespannt werden und sie erfordern nur einen relativ geringen konstruktiven Aufwand. Eine Parallelhaltung der Anhängestange zu den Drehachsen des Wickels bzw. des Wickelbaums lässt sich besonders einfach erzielen.The endless transport chains can also be complicated Curved tracks are stretched and they only require one relatively low design effort. A parallel pose the trailer rod to the axes of rotation of the coil or the Winding tree is particularly easy to achieve.

Gemäss den Figuren 1 und 3 ist in einer insgesamt mit 4 bezeichneten Wickelvorrichtung ein Fadenwickel, nämlich ein Schärwickel 2 auf einer Schärtrommel 5 aufgewickelt. Die Schärtrommel verfügt auf bekannte Weise auf einer Seite über einen Schärkonus 29, auf den die einzelnen Schärbänder 22 schichtweise gewickelt werden. Die Schärtrommel dreht sich zum Aufwickeln und Abwickeln der Fäden um die Drehachse 7 in einem Gestell 15.According to the figures 1 and 3 is in a total of 4 designated winding device a filament winding, namely a Schärwickel 2 wound on a warping drum 5. The Warping drum has in a known manner on one side over a warping cone 29, on the individual Schärbänder 22nd be wrapped in layers. The warping drum turns for winding and unwinding of the threads about the axis of rotation 7 in a frame 15.

Der bereits aus der EP-A-517 655 bekannte Vorgang zum Aufbau des Schärwickels 2 spielt sich wie folgt ab: Von einem hier nicht dargestellten Spulengatter wird ein Fadenverband 20 abgezogen und an einem Schärriet 21 zu einem Schärband 22 zusammengeführt. Das Schärriet sitzt auf einem Schärschlitten 23, der entsprechend der Konusneigung des Schärkonus und der zunehmenden Wickeldicke achsparallel und bezüglich seines Abstands zur Schärtrommel- radial verschiebbar ist. Ebenfalls am Schärschlitten 23 befestigt ist eine Umlenkwalze 24, um welche das Schärband 22 nach unten in Pfeilrichtung a auf die Schärtrommel aufgewickelt wird. Eine Presswalze 25 sorgt dafür, dass der Bandauftrag auf der Trommel egalisiert wird. Nachdem sämtliche Schärbänder in der erforderlichen Reihenfolge aufgewickelt wurden, wird das Fadenfeld 1 in der gesamten Breite in Pfeilrichtung b von der Schärtrommel 5 abgewikkelt und auf einen parallel daneben angeordneten Wickelbaum 3 aufgewickelt.The already known from EP-A-517 655 process for construction of Schärwickels 2 is as follows: From one here not shown creel is a thread assembly 20th subtracted and on a Schärriet 21 to a warp 22th merged. The shepherd sits on a sled 23, which corresponds to the cone slope of the Schärkonus and the increasing winding thickness paraxial and with respect to his Distance to the warping drum is radially displaceable. Likewise attached to the sharpening carriage 23 is a guide roller 24 to which the warp band 22 down in the direction of arrow a on the Warping drum is wound up. A press roll 25 provides for equalizing the band application on the drum. After all the heel bands in the required order were wound, the thread field 1 in the entire Width abgewikkelt in the direction of arrow b of the warping drum 5 and on a parallel arranged winding tree 3 wound.

Der Wickelbaum 3 ist in einem Maschinengestell 16 um eine Drehachse 6 drehbeweglich gelagert. Sowohl der Wickelbaum 3 als auch die Schärtrommel 5 stehen in Wirkverbindung mit Antriebsmitteln, Bremsmitteln und Steuerungsmitteln, die dem Fachmann jedoch allgemein bekannt sind. The winding tree 3 is in a machine frame 16 to a Rotary shaft 6 rotatably mounted. Both the winding tree 3 as well as the warping drum 5 are in operative connection with Drive means, brake means and control means provided for However, those skilled in the art are well known.

Bevor der Fadenwickel 2 abgewickelt werden kann, muss ersichtlicherweise der Anfang des Fadenfeldes 1 an den Wickelbaum 3 herangeführt und dort befestigt werden. Diese Uebergabe des Fadenfeldes erfolgt mit der Uebergabeeinrichtung 8, die sich über die Maschinengestelle 15 und 16 erstreckt. Sie besteht im wesentlichen aus zwei parallel zueinander geführten endlosen Transportketten 10 und 10', welche seitlich an Kettentraggestellen 19 und 19' aufgespannt sind. Zwischen den beiden Transportketten ist eine Anhängestange 9 mit ihren Enden 11 und 11' an den Ketten befestigt. Die Anhängestange verläuft dabei in jeder Kettenposition parallel zu den beiden Drehachsen 6 und 7. Sie ist lösbar mit den Transportketten verbunden.Before the filament winding 2 can be unwound, it must be apparent the beginning of the thread field 1 to the winding tree 3 introduced and fixed there. This transfer the thread field takes place with the transfer device 8, which extends over the machine frames 15 and 16. she consists essentially of two parallel to each other endless transport chains 10 and 10 ', which laterally Chain support frames 19 and 19 'are spanned. Between two transport chains is a trailer rod 9 with their Ends 11 and 11 'attached to the chains. The trailer rod runs in each chain position parallel to the two Rotary axes 6 and 7. It is detachable with the transport chains connected.

Beim Ausführungsbeispiel sind die Transportketten an ihren äussersten Enden um die Kettenumlenkräder 12 und 12' gespannt. Zusätzliche Kettenspannräder 14 sorgen dafür, dass die Ketten entlang einer bestimmten Führungsbahn gespannt sind. Der Antrieb erfolgt an wenigstens einem Kettenantriebsrad 13, das mit einem Antriebsmotor verbunden ist. Alternativ oder zusätzlich könnten die Transportketten auch über ein Handrad 28 betätigt werden. Die Synchronisation der beiden Transportketten kann dabei an geeigneter Stelle durch Getriebemittel vorgenommen werden. Zu diesem zweck könnte eine in Figur 3 angedeutete Getriebewelle 36 vorgesehen sein, welche die beiden Transportketten getriebemässig miteinander verbindet. Die Getriebestange ist in einem mittigen Bereich zwischen den beiden äussersten Kettenumlenkrädern 12 und 12' angeordnet, so dass sie dort nicht störend in Erscheinung tritt. Der Zugang zur Schärtrommel bzw. zum Wickelbaum ist damit auch von oben her ungehindert möglich.In the embodiment, the transport chains are at their outermost ends around the Kettenumlenkräder 12 and 12 'stretched. Additional chain tension wheels 14 ensure that the chains stretched along a certain guideway are. The drive takes place on at least one chain drive wheel 13, which is connected to a drive motor. alternative or additionally, the transport chains could also have one Handwheel 28 can be actuated. The synchronization of the two Transport chains can be at a suitable place by transmission means be made. For this purpose, an in Figure 3 indicated gear shaft 36 may be provided, which the two transport chains are geared together. The gear rack is in a central area between the two outermost Kettenumlenkrädern 12 and 12 ' arranged so that they are not disturbing in appearance occurs. The access to the warping drum or to the winding tree is so that it is possible without hindrance from above.

Die Transportketten verfügen über je ein oberes Kettentrum 26 und ein unteres Kettentrum 27. Da der Kettenantrieb reversibel ist, kann die Anhängestange sowohl über das untere als auch über das obere Kettentrum geführt werden. Wenigstens ein Abschnitt 35 der Transportketten ist von der Scheitellinie des vollen Wickels 34 auf der vom Wickelbaum 3 abgewandten Seite schräg nach unten gezogen.The transport chains each have an upper chain 26 and a lower chain end 27. Since the chain drive reversible is, the hitch can be both over the lower than also be guided over the upper chain. At least one Section 35 of the transport chains is from the apex line of the full roll 34 facing away from the winding tree 3 Page pulled obliquely downwards.

Zwischen den beiden Kettentrums 26 und 27 ist ein Behandlungsmodul, beispielsweise eine Schlichte- oder Wachsvorrichtung angeordnet. An diesem Behandlungsmodul kann das Fadenfeld 1 über eine Behandlungswalze 18 geführt werden, wobei eine Beschichtung mit einem beliebigen Behandlungsmittel erfolgt. Je nachdem, ob eine Behandlung des Fadenfeldes gewünscht ist, muss das Fadenfeld ersichtlicherweise über die Behandlungswalze 18 geführt werden oder gestreckt unter der Behandlungswalze durch. Anstelle der Behandlungswalze könnte aber auch eine einfache Umlenkwalze treten, welche dazu dient, den Kettzug beim Bäumen zu messen bzw. zu regeln. Auch eine sogenannte Sickenwalze zum Lösen zusammenhängender Kettfäden könnte zwischen den Kettentrums 26 und 27 angeordnet und durch das Fadenfeld wahlweise beaufschlagt oder umgangen werden.Between the two chain centers 26 and 27 is a treatment module, For example, a sizing or waxing device arranged. At this treatment module, the Thread field 1 are passed over a treatment roller 18, being a coating with any treatment agent he follows. Depending on whether a treatment of the thread field is desired, the thread field has evidently over the treatment roller 18 are guided or stretched under the treatment roller through. Instead of the treatment roller But could also occur a simple guide roller, which serves to measure or regulate the warp in trees. Also a so-called bead roll for releasing coherent Warp threads could be placed between the warp centers 26 and 27 and optionally acted upon by the thread field or to be bypassed.

In Figur 1 ist mit Dmax der maximale Aussendurchmesser des Fadenwickels 2 und mit Dmin der minimale Aussendurchmesser dargestellt. Der Aussendurchmesser des Wickelbaums 3 definiert den minimalen Aussendurchmesser dmin vor Beginn des Bäumprozesses und mit dmax ist der maximale Aussendurchmesser des Kettbaumes am Ende des Bäumvorgangs bezeichnet. Die Behandlungswalze 18 ist so angeordnet, dass das Fadenfeld sowohl am Anfang als auch am Ende des Bäumprozesses gestreckt unterhalb der Behandlungswalze vorbeigeführt wird. Für die Uebergabe des Fadenfeldes ohne Behandlung im Behandlungsmodul 17 wird es rechts in der Abbildung an die Anhängestange 9 angehängt. Anschliessend werden die Transportketten in Pfeilrichtung d bewegt, so dass die Anhängestange 9 am unteren Kettentrum 27 unterhalb der Behandlungswalze 18 vorbeigeführt wird, bis sie etwa über dem Wickelbaum 3 angelangt ist. Anschliessend wird das Fadenfeld aus der Anhängestange 9 gelöst und am Wickelbaum 3 befestigt. Es kann dabei vorteilhaft sein, dass die Anhängestange 9 leicht lösbar an den Transportketten befestigt ist, z.B. durch Einhängehaken.In FIG. 1, Dmax is the maximum outside diameter of Filament winding 2 and with Dmin the minimum outer diameter shown. The outer diameter of the winding tree 3 defined the minimum outside diameter dmin before the start of the Tree process and with dmax is the maximum outside diameter of the warp beam at the end of the tree process. The Treatment roller 18 is arranged so that the thread field stretched both at the beginning and at the end of the tree process is passed below the treatment roller. For the Transfer of the thread field without treatment in the treatment module 17 it is on the right in the figure to the trailer rod 9 attached. Subsequently, the transport chains in the direction of arrow d moves, so that the trailer rod 9 at the bottom Chain center 27 passed below the treatment roller 18 is until it has reached about the winding tree 3. Subsequently, the thread field from the trailer rod. 9 solved and attached to the winding tree 3. It can be advantageous be that the trailer rod 9 easily detachable to the Transport chains is attached, e.g. by hanging hook.

Figur 2 zeigt einen Uebergabevorgang, bei dem während des Bäumprozesses eine Behandlung des Fadenfeldes an der Behandlungswalze 18 gewünscht ist. Das Fadenfeld wird wiederum auf die gleiche Weise an die Anhängestange 9 in der Ausgangsstellung befestigt. Anschliessend werden die Transportketten jedoch in Pfeilrichtung c bewegt, wobei die Anhängestange 9 auf dem oberen Kettentrum 26 über die Behandlungswalze 18 hinweggeführt wird, bis sie wiederum etwa über dem Wickelbaum 3 angelangt ist. Das Behandlungsmodul 17 wird auf diese Weise vom Fadenfeld überfahren und es legt sich beim Befestigen am Wickelbaum 3 unter einem bestimmten Umschlingungswinkel auf die Behandlungswalze 18. Dieser Umschlingungswinkel ändert sich beim späteren Bäumprozess mit zunehmender Baumwickeldicke nur geringfügig.Figure 2 shows a transfer operation in which during the Bäumprozesses a treatment of the thread field on the treatment roller 18 is desired. The thread field will turn on the same way to the trailer rod 9 in the starting position attached. Subsequently, the transport chains However, moves in the direction of arrow c, the trailer rod 9 on the upper chain 26 via the treatment roller 18th is carried away until it is again about the winding tree 3 has arrived. The treatment module 17 becomes this way run over by the thread field and it attaches to the fastening on Winding tree 3 under a certain wrap on the treatment roller 18. This wrap angle changes during the later tree process with increasing tree winding thickness only slightly.

Figur 4 zeigt ein Beispiel für die Konstruktion einer Anhängestange 9. Diese besteht hier aus einer unteren Klemmleiste 30 und aus einer oberen Klemmleiste 31. Die beiden Klemmleisten sind an einem Gelenk 32 miteinander verbunden, so dass sie zweiarmige Hebel bilden. Eine Druckfeder 33 presst die Klemmseite der beiden Klemmleisten gegeneinander, so dass das Fadenfeld 1 klemmend angehängt werden kann. Es sind hier aber diverse alternative Möglichkeiten denkbar. Der Ausdruck Anhängestange erfasst grundsätzlich alle Mittel, die sich zum Festhalten des Fadenfeldes eignen. Es könnte sich somit auch um eine Reihe einzelner Kluppen handeln, die kraftschlüssig miteinander verbunden sind.Figure 4 shows an example of the construction of a suspension rod 9. This consists of a lower terminal strip 30 and from an upper terminal block 31. The two terminal strips are connected together at a joint 32, so that they form two-armed levers. A compression spring 33 presses the clamping side of the two terminal strips against each other, so that the thread field 1 can be attached by clamping. It is here but various alternative possibilities conceivable. The expression Hitch rod basically covers all means that can be used for Holding the thread field are suitable. It could be too to act a series of individual clips that are non-positively connected to each other.
