Description

Die Erfindung betrifft ein Fadenmessliefergerät gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a Fadenmessliefergerät according to the preamble of claim 1.

Fadenmessliefergeräte werden an Düsenwebmaschinen, insbesondere Luftdüsenwebmaschinen eingesetzt, um Schussfadenmaterial von einem Fadenspeicher abzuziehen, auf dem Speicherkörper in aneinanderliegenden oder voneinander separierten Windungen zwischenzuspeichem, die gespeicherten Fadenwindungen in Richtung zum Frontende des Speicherkörpers vorwärts zu fördern, für jeden Eintragvorgang nur eine durch die Stoppvorrichtung bemessene Anzahl von Windungen zum Abzug freizugeben, den Schuss einzuleiten, und schließlich z.B. mittels der Stoppvorrichtung den Schuss zu beenden.Fadenmessliefergeräte be used on jet looms, especially air jet looms to deduct weft thread material from a thread storage on the storage body in adjacent or separated windings zwischenzuspeichem forward the stored turns of thread towards the front end of the storage body, for each entry process only one measured by the stop number from turns to the trigger to release, initiate the shot, and finally, for example stop the shot by means of the stopping device.

Ferner sind Fadenmessliefergeräte bekannt WO-A-02/33157 , die einen Speicherkörper mit extrem kleinem Durchmesser sowie eine Stoppvorrichtung mit einem Stoppstift aufweisen, der die jeweils zum Abzug freizugebende Anzahl der Fadenwindungen bemisst und den Schuss beendet, während eine in Abzugsrichtung vor dem Speicherkörper angeordnete, gesteuerte Fadenklemme jeden Schuss einleitet. Die vom Aufwickelelement auf der Speicherfläche gebildeten Windungen werden sukzessive vorwärts geschoben, wobei sie den Stoppstift bis in eine vorbestimmte Endstellung mitbewegen. Da jeder Schuss von der gesteuerten Fadenklemme eingeleitet wird, und das Fontende des Speicherkörpers knapp hinter der Endstellung des Stoppstiftes liegt, werden bis zum Beginn des nächsten Schusses mehrere Fadenwindungen über das Frontende hinweg in einer rohrförmigen Konfiguration freigesetzt, die bis zum und während des Schusses ohne innere Abstützung sozusagen frei im Raum verharren und dann bis zum Stoppstift zurück abgezogen werden. Gegebenenfalls werden nur äußere Führungsflächen für die freigesetzten Fadenwindungen vorgesehen. Dieses Prinzip ermöglicht hohe Schussfrequenzen mit hoher Schussgeschwindigkeit und relativ moderate Drücke für die Eintragdüsen der Webmaschine, vor allem weil durch das Freisetzen der Windungen ohne jegliche innere Abstützung und mit dem kleinen Speicherkörperdurchmesser eine den Abzug hemmende Ballonbildung weitestgehend unterbleibt. Allerdings besteht beim Aufzehren der freigesetzten Fadenwindungen die Gefahr einer Schlingenbildung, die zu Gewebefehlern und/oder Fadenbrüchen führen kann. Denn es können manchmal zwei Windungen aneinander hängen bleiben und zugleich abgezogen werden. Es wird deshalb manchmal ein in Abzugsrichtung über das Frontende des Speicherkörpers hinausragender, zentraler Stift zentral am Speicherkörper angebracht, der die Gefahr der Schlingenbildung beseitigen soll. Die Praxis zeigt jedoch, dass manche Schussfadenmaterialien dennoch zur Schlingenbildung tendieren.Furthermore, thread measuring devices are known WO-A-02/33157 having a storage body with an extremely small diameter and a stop device with a stop pin, which measures the respective number of thread turns to be released for withdrawal and terminates the shot, while a withdrawal direction in front of the storage body arranged, controlled thread clamp initiates each shot. The turns formed by the take-up on the storage surface are successively pushed forward, while they move the stop pin to a predetermined end position. Since each shot is initiated by the controlled thread clamp, and the end of the storage body is just past the end position of the stop pin, multiple turns of thread are released across the front end in a tubular configuration until the start of the next shot, up to and during the shot inner support so to speak, remain free in the room and then pulled back to the stop pin back. Optionally, only outer guide surfaces are provided for the liberated thread turns. This principle allows high firing frequencies with high firing speed and relatively moderate pressures for the entry nozzles of the loom, especially because by the release of the windings without any inner support and with the small storage body diameter a withdrawal inhibiting balloon formation largely avoided. However, there is a risk when consuming the released thread turns a looping that can lead to tissue defects and / or thread breakages. Because sometimes two turns can get stuck together and be deducted at the same time. It is therefore sometimes a projecting in the withdrawal direction on the front end of the storage body, central pin mounted centrally on the storage body, which should eliminate the risk of looping. However, practice shows that some weft materials still tend to loop.

Aus DE-A-29 20 629 ist ein Fadenmessliefergerät bekannt, dessen Speicherkörper aus einem bezüglich der Achse des Speicherkörpers exzentrischen, im Wesentlichen zylindrischen Gehäuse mit einem wesentlich kleineren Außendurchmesser als dem Außendurchmesser des Speicherkörpers, sowie in dem zylindrischen Gehäuse radial verstellbaren L-förmigen Bügeln besteht. Das zylindrische Gehäuse wird am Frontende des Speicherkörpers durch eine radial liegende Wand abgedeckt. Die radialen Schenkel der Bügel sind gegenüber der Wand geringfügig zurückgesetzt. Im Inneren des zylindrischen Gehäuses sind mehrere Stoppstifte durch ein Getriebe umlaufend angetrieben, die alternierend über den Außenumfang des Speicherkörpers ausgefahren und wieder eingefahren werden.Out DE-A-29 20 629 a Fadenmessliefergerät is known, the storage body consists of a respect to the axis of the storage body eccentric, substantially cylindrical housing having a substantially smaller outer diameter than the outer diameter of the storage body, as well as in the cylindrical housing radially adjustable L-shaped brackets. The cylindrical housing is covered at the front end of the storage body by a radially disposed wall. The radial legs of the bracket are slightly set back against the wall. Inside the cylindrical housing, a plurality of stop pins are peripherally driven by a gear, which are extended and retracted alternately over the outer periphery of the storage body.

Der Erfindung liegt die Aufgabe zugrunde, ein Fadenmessliefergerät anzugeben, bei dessen Operation mit hoher Schussfrequenz und Schussgeschwindigkeit eine Schlingenbildung zuverlässig vermieden wird.The invention has for its object to provide a Fadenmessliefergerät, in the operation with high firing frequency and firing speed looping is reliably avoided.

Die gestellte Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The stated object is achieved with the features of claim 1.

Der Verlängerungsteil bietet den Fadenwindungen vor dem und während des Schusses eine nur lokale innere Abstützung. Die Auflage und die zur Auflage konvergierende Gegenfläche bewirken, dass jede über das Frontende des Speicherkörpers freikommende Fadenwindung praktisch fast nur punktuell an der Auflage abgestützt wird, hingegen beim Abzug über den Rest ihrer 360°-Erstreckung ohne jegliche innere Abstützung und ohne Balloneffekt nach innen im Wesentlichen zur Verlängerung der Achse des Speicherkörpers gezogen wird. Die Reibung an der Auflage und die durch die Auflage bei der Abzugsbewegung hervorgerufene Unregelmäßigkeit im Fadenlauf führen überraschend zuverlässig dazu, dass jede vorderste Fadenwindung separiert und alleine abgezogen wird. Dadurch ist die Gefahr einer Schlingenbildung beseitigt. Die schräge Gegenfläche verhindert ferner, dass sich Windungen an dem Verlängerungsteil festziehen, da jede sich zusammenziehende Windung durch die Schräge der Gegenfläche vom Verlängerungsteil abgeschoben wird. Die Gegenfläche kann am Außendurchmesser des Speicherkörpers beginnen. Im einfachsten Fall ist der Verlängerungsteil eine Art rechtwinkliges Dreieck, z.B. als zweidimensionale ebene Fläche oder nur aus Stäben, die eine Kathete und die Hypotenuse des zumindest weitgehend rechtwinkligen Dreiecks definieren. Es unterbleibt eine spürbare und störende Ballonwirkung, weil jede Windung beim Abzug über den größten Teil vom 360° sofort nach innen in Richtung zur Verlängerung der Achse des Speicherkörpers gezogen wird. Die Fadenwindungen werden beim Abzugs sauber und geordnet aufeinanderfolgend aufgezehrt, bis schließlich der gestreckte Schussfaden vom Verlängerungsteil freigekommen ist und sich direkt zum Stoppstift der Stoppvorrichtung erstreckt, der den Schuss beendet. Das positive Resultat des Einflusses des Verlängerungsteils ist überraschend, weil eigentlich anzunehmen ist, dass ein Verlängerungsteil im Abzugsweg von der Speicherfläche zur Webmaschine Nachteile mit sich bringen müsste.The extension part provides the thread turns before and during the shot only a local inner support. The support and the counter surface converging to the support cause each Fadenwindung free on the front end of the storage body practically almost only selectively supported on the support, while the trigger over the rest of their 360 ° extension without any inner support and without balloon effect inside in Essentially to extend the axis of the storage body is pulled. The friction on the support and caused by the support during the withdrawal movement irregularity in the yarn path lead surprisingly reliable that each foremost Fadenwindung separated and withdrawn alone. This eliminates the risk of looping. The oblique mating surface further prevents turns from being tightened on the extension portion, as each contracting turn is deported by the slope of the mating surface from the extension portion. The counter surface can start at the outer diameter of the storage body. In the simplest case, the extension part is a kind of right-angled triangle, eg as a two-dimensional flat surface or only of rods which define a catheter and the hypotenuse of the at least substantially right-angled triangle. There is no noticeable and disturbing effect of the balloon, because every turn of the trigger pulls it over the largest part of the 360 ° immediately inward in the direction of the extension of the axis of the storage body becomes. The turns of thread are cleanly and successively consumed at the trigger successive until finally the stretched weft thread is released from the extension part and extends directly to the stop pin of the stop, which ends the shot. The positive result of the influence of the extension part is surprising because it is actually to be assumed that an extension part in the withdrawal path from the storage surface to the weaving machine would have to bring disadvantages.

Die Positionierung der Auflage an einer in Bezug auf die Richtung der Gravitation oben liegenden Stelle des Speicherkörpers führt zu dem Vorteil einer symmetrischen Aufhängeabstützung der Fadenwindungen unter Vermeidung störender exzentrischer Fadenbewegungen beim Abzug. Ferner wird durch die zentrale oben liegende Position der Auflage jede darauf reitende Fadenwindung so abgestützt, dass sie sich nicht um die Achse des Speicherkörpers drehverlagern kann. Ein Linienkontakt zwischen den Fadenwindungen und der Auflage reicht aus, um die erforderliche Aufhängeabstützung zu erbringen, und resultiert auch in geringem Reibungswiderstand für die Fadenwindungen. Dennoch ist es sogar möglich, flächige oder breitere Auflagen einzusetzen, etwa um die Fadenwindungen unter Nutzen der natürlichen Krümmungsspeicherfähigkeit des Fadenmaterials weit geöffnet zu halten. Wenn die vom Speicherkörper freigekommenen Fadenwindungen hingegen ohnedies von unten auf einer Führungsfläche abgestützt sind, könnte der Verlängerungsteil z.B. alternativ auch eine 9-Uhr-Position am Speicherkörper einnehmen.The positioning of the support on a location of the storage body which is located at the top in relation to the direction of gravity leads to the advantage of a symmetrical suspension support of the thread windings while avoiding disturbing eccentric thread movements during the withdrawal. Furthermore, each thread turn riding on it is supported by the central overhead position of the support so that it can not rotatably shift about the axis of the storage body. Line contact between the turns of thread and the support is sufficient to provide the required suspension support, and also results in low frictional resistance to the turns of thread. Nevertheless, it is even possible to use flat or broader conditions, such as to keep the thread turns wide open by taking advantage of the natural curvature storage capacity of the thread material. On the other hand, if the filament turns freed from the storage body are supported from below on a guide surface, the extension part could e.g. Alternatively take a 9 o'clock position on the storage body.

Zweckmäßig wird die Speicherfläche des Speicherkörpers von Außenflächen um die Achse mit Zwischenräumen verteilter Finger definiert. Die Finger enden, vorzugsweise, frei am Frontende des Speicherkörpers. Die Auflage des Verlängerungsteils verlängert die Außenfläche eines der Finger. Dabei ist es günstig, wenn zwischen der Auflage und der Außenfläche des Fingers kein für die Fadenwindungen spürbarer Übergang vorliegt.Suitably, the storage surface of the storage body is defined by outer surfaces about the axis with spaces of distributed fingers. The fingers end, preferably, freely at the front end of the storage body. The overlay of the extension extends the outer surface of one of the fingers. It is advantageous if there is no tangible transition between the support and the outer surface of the finger.

Der Verlängerungsteil, dessen Auflage die Außenfläche des Fingers verlängert, sollte zweckmäßig direkt am Finger angebracht sein. Gegebenenfalls ist der Verlängerungsteil sogar einstückig mit dem Finger ausgebildet.The extension part, the support extends the outer surface of the finger, should be appropriate attached directly to the finger. Optionally, the extension part is even formed integrally with the finger.

Um unter betriebsbedingten Vibrationen Eigenbewegungen des Verlängerungsteils so zu unterdrücken, könnte der Verlängerungsteil zusätzlich am Speicherkörper abgestützt sein, beispielsweise an einem diametral gegenüberliegenden anderen Finger.In order to suppress proper movements of the extension part under operating vibrations, the extension part could additionally be supported on the storage body, for example on a diametrically opposite other finger.

Da für unterschiedliche Fadenmaterialien gegebenenfalls verschiedene Formen des Verlängerungsteils optimale Wirkung erbringen, ist es zweckmäßig, wenn der Verlängerungsteil gegen einen anderen mit anderer Form ausgebildeten Verlängerungsteil austauschbar am Speicherkörper angebracht ist.Since different shapes of the extension part may provide optimal effect for different thread materials, it is expedient if the extension part is mounted exchangeably on the storage body against another extension part formed with a different shape.

Bei einer einfachen Ausführungsform ist der Verlängerungsteil ein Stab, z.B. aus Kunststoff oder Draht. Alternativ könnte auch eine Klinge vorgesehen sein, deren Schneide oder Rücken die Auflage bildet.In a simple embodiment, the extension part is a rod, e.g. made of plastic or wire. Alternatively, a blade could be provided, the cutting edge or back forms the support.

Die schräge Gegenfläche, die sich zusammenziehende Fadenwindungen vom Verlängerungsteil abschiebt, ist zweckmäßig sogar in den Verlängerungsteil eingegliedert.The oblique mating surface, which shunts contracting turns of thread from the extension part, is expedient even incorporated into the extension part.

Bei einer anderen Ausführungsform kann der Verlängerungsteil ein schiefer Kegel oder Kegelstumpf sein. Der Basisdurchmesser des Kegels oder Kegelstumpfs kann kleiner sein als der Durchmesser des Frontendes des Speicherkörpers. Dann entspannt sich jede die Auflage erreichende Fadenwindung sofort über den größten Teil ihrer 360°-Erstreckung. Der Kegel oder Kegelstumpf bildet sowohl die Auflage als auch die Gegenfläche.In another embodiment, the extension part may be a slate cone or truncated cone. The base diameter of the cone or truncated cone may be smaller than the diameter of the front end of the storage body. Then each thread turn reaching the overlay relaxes immediately over most of its 360 ° extension. The cone or truncated cone forms both the support and the counter surface.

Ein Kegel oder Kegelstumpf als Verlängerungsteil könnte eine gerade, konvexe oder konkave Erzeugende aufweisen.A cone or truncated cone as an extension part could have a straight, convex or concave generatrix.

Alternativ könnte der Verlängerungsteil auch ein Hohlkörper mit oberen und unteren Schmalseiten und einem rechteckigen oder ovalen Querschnitt sein. Die Querschnittsweite sollte mindestens der Breite der Außenfläche des Fingers entsprechen, von welchem der Verlängerungsteil ausgeht.Alternatively, the extension part could also be a hollow body with upper and lower narrow sides and a rectangular or oval cross-section. The cross-sectional width should correspond at least to the width of the outer surface of the finger from which the extension part extends.

In diesem Fall lässt sich die Auflage bequem von einer Schmalseite des Hohlkörpers bilden, wobei diese Schmalseite zweckmäßig entweder leicht gekrümmt oder im Mittelbereich flach und an den Rändern abgerundet sein sollte. Die gegenüberliegende Schmalseite des Hohlkörpers bildet die in Abzugsrichtung schräg bis zu einem Spitzenbereich des Hohlkörpers zurückweisende Gegenfläche. Die Gegenfläche könnte innerhalb des Außendurchmessers des Speicherkörpers beginnen, falls in diesem Bereich Platz für andere Fadensteuerglieder des Fadenmessliefergerätes benötigt wird.In this case, the support can be conveniently formed by a narrow side of the hollow body, this narrow side should be either slightly curved or rounded in the middle area flat and rounded at the edges. The opposite narrow side of the hollow body forms in the withdrawal direction obliquely to a tip region of the hollow body rejecting counter surface. The mating surface could begin within the outer diameter of the storage body, if space is needed in this area for other thread control members of the Fadenmessliefergerätes.

Die Auflage kann parallel oder konvergierend zur Achse verlaufen. Eine bestimmte Konvergenz oder fallende Krümmung kann das Vorwärtsschieben der Fadenwindungen und/oder das Aufzehren der Fadenwindungen beim Abzug erleichtern.The support may be parallel or converging to the axis. A certain convergence or falling curvature may facilitate forward feeding of the turns of thread and / or the consumption of turns of thread on withdrawal.

Günstig ist es ferner, an der Auflage einen in Abzugsrichtung abfallenden Endabschnitt vorzusehen. Dies begünstigt den Abzugsvorgang und verhindert, dass eine am Ende der Auflagefläche ankommende Fadenwindung herabfällt.It is also favorable to provide an end section which slopes down in the take-off direction on the support. This favors the withdrawal process and prevents falling at the end of the support surface Fadenwindung falls.

Wenn die Gegenfläche einen in etwa zur Achse des Speicherkörpers parallelen Endabschnitt aufweist, wird die Neigung der freigesetzten Fadenwindungen, sich beim Abzug von der Auflage abzuheben, gemildert.If the mating surface has an end portion approximately parallel to the axis of the storage body, the tendency of the loosened turns of thread to lift off the support during withdrawal is alleviated.

Damit der von den Fadenwindungen mitgenommene Stoppstift keinen störenden Einfluss auf die korrekte Anordnung der Fadenwindungen an der Oberseite des Speicherkörpers und auf der Auflage nimmt, ist es zweckmäßig, den Stoppstift an einer in Bezug auf die Richtung der Gravitation unten liegenden Stelle des Speicherkörpers vorzusehen. Zweckmäßig arbeitet der Stoppstift mit dem Finger zusammen, der dem von der Auflage verlängerten Finger in etwa diametral gegenüberliegt. Grundsätzlich sollte der Verlängerungsteil eine geometrische Form haben, die sicherstellt, dass der gegen Ende des Abzugvorgangs sich streckende Faden in keinem Fall am Verlängerungsteil hängen bleibt, sondern sich vom Verlängerungsteil befreit und direkt bis zum Stoppstift erstreckt.In order for the stop pin taken along by the thread windings to have no disturbing influence on the correct arrangement of the thread windings on the upper side of the storage body and on the support, it is expedient to provide the stop pin on a location of the storage body lying below in relation to the direction of gravitation. The stop pin expediently cooperates with the finger, which lies diametrically opposite the finger extended by the rest. In principle, the extension part should have a geometric shape, which ensures that at the end of the withdrawal process extending thread in no case gets caught on the extension part, but freed from the extension part and extends directly to the stop pin.

Zweckmäßig ist es ferner, wenn der Stoppstift, der in und gegen die Abzugsrichtung sowie radial bewegbar angeordnet ist, in einen Führungsschlitz des Speicherkörpers eingreift, der die Endposition des Stoppstiftes bei der durch die Fadenwindungen bewirkten Bewegung des Stoppstiftes definiert, in der der Stoppstift den Eintragvorgang beendet. Zum Einleiten eines Eintragvorgangs und zum Halten des Schussfadens während der Betriebsphase, in der nach Zurückziehen des Stoppstiftes weitere Fadenwindungen über das Frontende des Speicherkörpers freigesetzt und auf der Auflage platziert werden, ist eine gesteuerte Fadenklemme stromab des Frontendes des Speicherkörpers zweckmäßig.It is also expedient if the stop pin, which is arranged in and against the withdrawal direction and radially movable, engages in a guide slot of the storage body, which defines the end position of the stop pin in the thread turns caused by the movement of the stop pin, in which the stop pin the entry process completed. To initiate a picking operation and to hold the weft during the operating phase in which after retraction of the stop pin further thread turns are released via the front end of the storage body and placed on the support, a controlled thread clamp downstream of the front end of the storage body is appropriate.

Eine unterhalb des Speicherkörpers in Abzugsrichtung hinter dem Frontende liegende Führungsfläche leistet eine zusätzliche, das Abzugsverhalten begünstigende Abstützung der freigekommenen Fadenwindungen, jedoch nur von außen an dem rohrförmig konfigurierten, freigesetzten Fadenwickel.A lying below the storage body in the withdrawal direction behind the front end guide surface makes an additional, the withdrawal behavior favoring support the freed yarn turns, but only from the outside of the tubular configured, released filament winding.

Da sich bei der Kinematik des Schusses die Tendenz abzeichnen kann, dass die vom Speicherkörper abgeschobenen Fadenwindungen sich von der Auflage abzuheben suchen und/oder Schlingen bilden, ist es zweckmäßig, oberhalb des Speicherkörpers und in Abzugsrichtung eine bis hinter das Frontende reichende äußere Abdeckfläche vorzusehen. Dadurch lässt sich das Abzugsverhalten bzw. die Fadengeometrie beim Schuss verbessern.Since the trend in the kinematics of the weft may indicate that the thread turns pushed off the storage body seek to lift off the support and / or form loops, it is expedient to provide an outer covering area extending beyond the front end above the storage body and in the withdrawal direction. As a result, the trigger behavior or the thread geometry during the shot can be improved.

Um das Hochsteigen der freigesetzten Fadenwindungen und/oder die Schlingenbildung beim Abzug zu vermeiden, ist es zweckmäßig, wenn die Abdeckfläche nach außen nachgiebig angeordnet ist und mit der Außenfläche des Fingers und der Auflage einen Fadenwindungskontrollspalt definiert. In diesem Spalt werden die Fadenwindungen geordnet nebeneinander gehalten und beim Durchschieben geführt.In order to avoid the rising of the liberated thread turns and / or the loop formation during the withdrawal, it is expedient if the cover surface is arranged to be yielding outwards and defines a thread turn control gap with the outer surface of the finger and the support. In this gap, the turns of thread are arranged next to each other in order and guided while pushing.

Dabei ist es zweckmäßig, wenn die Abdeckfläche von außen gegen die Außenfläche des Fingers und die Auflage elastisch vorgespannt ist. Unregelmäßigkeiten im Faden und/oder Knoten können dadurch unbehindert passieren.It is expedient if the cover surface is elastically biased from the outside against the outer surface of the finger and the support. Irregularities in the thread and / or knots can thus happen unhindered.

Um die Fadenwindungen entlang ihres Weges vom Finger auf die Auflagefläche kontrolliert zu verlagern ist es zweckmäßig, dass sich die Abdeckfläche, beginnend im Abstand vom Aufwickelelement entlang des Fingers und der Auflage bis über das Ende der Auflage hinaus erstreckt. In dem Bereich, in welchem sich die Abdeckfläche über das Ende der Auflage hinaus erstreckt, unterdrückt die Abdeckfläche die Tendenz der freigesetzten Windungen, beim Abzug aufzusteigen.In order to shift the yarn turns along their path from the finger to the support surface in a controlled manner, it is expedient for the cover surface to extend beyond the end of the support, starting at a distance from the take-up element along the finger and the support. In the region in which the cover surface extends beyond the end of the support, the cover surface suppresses the tendency of the released turns to ascend upon withdrawal.

Zweckmäßig wird die Abdeckfläche von der Unterseite eines Federelements gebildet. Dies kann flächig oder stab- bzw. linienförmig sein.Suitably, the cover surface is formed by the underside of a spring element. This can be flat or rod-shaped or linear.

Bei einer zweckmäßigen Ausführungsform ist das Federelement eine Blattfeder, die in einer stationären Stütze nachgiebig gehaltert ist. Zweckmäßig ist die Blattfeder um eine Kippachse nachgiebig auslenkbar, die in etwa parallel zur Speicherkörperachse verläuft und seitlich versetzt zum Kontaktbereich zwischen der Blattfeder und der Auflage angeordnet ist. Dadurch kann die Blattfeder mit relativ gleich bleibender Kraft auf die Fadenwindungen einwirken und dennoch leicht nachgeben.In an expedient embodiment, the spring element is a leaf spring, which is resiliently held in a stationary support. Suitably, the leaf spring is resiliently deflectable about a tilt axis, which extends approximately parallel to the storage body axis and laterally offset from the contact region between the leaf spring and the support is arranged. As a result, the leaf spring with relatively constant force acting on the turns of thread and still yield slightly.

Bei einer bevorzugten Ausführungsform ist die Blattfeder in der Stütze mit mindestens einem Federkörper festgelegt, der für die Positionierung der Blattfeder sorgt und ihre leichte Ausweichbewegung zulässt.In a preferred embodiment, the leaf spring is fixed in the support with at least one spring body, which provides for the positioning of the leaf spring and allows their easy evasive movement.

Zweckmäßig besitzt die Blattfeder an zumindest einem Ende, vorzugsweise dem dem Aufwickelelement zugewandten Ende, eine vom Speicherkörper weg orientierte Aufbiegung. Dies ermöglicht einen schonenden Eintritt der Fadenwindungen in den Kontrollspalt und verhindert die Gefahr, dass sich Fadenwindungen an der Blattfeder stauen.The leaf spring expediently has at least one end, preferably the end facing the winding element, a bend oriented away from the storage body. This allows a gentle entry of the thread turns in the control gap and prevents the risk that thread turns accumulate on the leaf spring.

Ein in Fig. 1 gezeigtes Fadenmessliefergerät F, etwa entsprechend dem aus WO-A-02/33157 bekannten Messliefergerät, weist ein einen nicht gezeigten Antriebsmotor für ein Aufwickelelement 2 enthaltendes Gehäuse 1 auf, an dem ein Speicherkörper K stationär angeordnet ist, um dessen im Wesentlichen zylindrische Speicherfläche 6 das Aufwickelelement 2 drehbar ist. Der Speicherkörper K hat eine Achse X und entweder einen festgelegten oder einen variablen Durchmesser. Beim Gehäuse 1 ist wenigstens eine Stoppvorrichtung S mit einem Stoppstift 3 angeordnet, der in Kooperation mit dem Speicherkörper K zum Bemessen der jeweils zum Abzug freizugebenen Anzahl an Fadenwindungen dient. Die Fadenwindungen werden mit Hilfe des Aufwickelelementes 2 erzeugt und direkt aneinanderliegend oder voneinander separiert auf der Speicherfläche 6 zwischengespeichert. Der Stoppstift 3 kann mit einer als Führungsschlitz 4 ausgebildeten Vertiefung im Speicherkörper K zusammenwirken und ist radial zur Achse X hin- und herbewegbar, sowie in und gegen die Abzugsrichtung W des nicht gezeigten Fadens aus den Fadenwindungen auf der Speicherfläche 6.An in Fig. 1 Shown Fadenmessliefergerät F, approximately in accordance with the WO-A-02/33157 known Meßliefergerät, has a not shown drive motor for a take-up 2 containing housing 1, on which a storage body K is arranged stationary, about its substantially cylindrical storage surface 6, the take-up element 2 is rotatable. The storage body K has an axis X and either a fixed or a variable diameter. When the housing 1 at least one stop device S is arranged with a stop pin 3, which is used in cooperation with the storage body K for dimensioning the release of each deducted number of turns of thread. The turns of thread are produced by means of the take-up element 2 and are directly adjacent to one another or separated from one another the memory area 6 cached. The stop pin 3 can cooperate with a recess formed as a guide slot 4 in the storage body K and is radially to the axis X back and forth, as well as in and against the withdrawal direction W of the thread not shown from the thread turns on the storage surface. 6

Der Stoppstift 3 wird bei rotierendem Aufwickelelement 2 nahe beim Aufwickelelement 2 aus einer zurückgezogenen Stellung zwischen zwei aufeinanderfolgende Fadenwindungen in den Führungsschlitz 4 eingeführt und dann ausschließlich durch die aus dem Aufwickelvorgang und/oder von einer nicht gezeigten Separiereinrichtung resultierende Vorwärtsbewegung der Fadenwindungen in Abzugsrichtung W bis in eine im Führungsschlitz 4 definierte Endposition (annähernd wie gezeigt) bewegt, um den Fadenabzug zu beenden (Ende eines Eintragvorgangs).The stop pin 3 is introduced at a rotating winding element 2 near the winding element 2 from a retracted position between two successive turns of thread in the guide slot 4 and then exclusively by the resulting from the winding and / or by a separating device, not shown, forward movement of the thread turns in the drawing direction W to an end position defined in the guide slot 4 (approximately as shown) moves to end the thread withdrawal (end of an entry process).

Der Speicherkörper 6 weist ein Frontende 5 auf, vor dem sich in Abzugsrichtung W eine gesteuerte Fadenklemme C befindet, die zum Einleiten jeweils eines Eintragvorgangs und zum vorübergehenden Festlegen des sich von der nicht gezeigten Eintragvorrichtung der Webmaschine zum Speicherkörper 6 erstreckenden Schussfadens dient.The storage body 6 has a front end 5, in front of which a controlled thread clamp C is in the withdrawal direction W, which serves for initiating a respective picking operation and temporary fixing of the not shown feeding device of the weaving machine to the storage body 6 weft thread.

Der Stoppstift 3 ist z.B. in Bezug auf die Richtung der Gravitation G an einem untenliegenden Bereich des Speicherkörpers K angeordnet.The stop pin 3 is e.g. with respect to the direction of gravitation G at a lower region of the storage body K arranged.

An einer in Bezug auf die Richtung der Gravitation G z.B. oben liegenden Stelle 7 am Speicherkörper K ist ein über das Frontende 5 vorstehender Verlängerungsteil V vorgesehen (einstückig oder austauschbar), der eine sich im Wesentlichen in Abzugsrichtung W erstreckende, zumindest linienförmige Auflage A zum in diesem Ausführungsbeispiel hängenden Abstützen von der Speicherfläche 6 freigesetzter Fadenwindungen bildet. Der Auflage A im Wesentlichen diametral gegenüberliegend ist eine Gegenfläche 16 zugeordnet. Diese beginnt am Außendurchmesser der Speicherfläche 6 oder etwas weiter innen, und weicht in Abzugsrichtung W schräg, hier nach oben, zurück.At one with respect to the direction of gravity G, for example, overhead location 7 on the storage body K is provided over the front end 5 protruding extension part V (in one piece or interchangeable), which is a substantially extending in the withdrawal direction W, at least line support A for this embodiment hanging supports from the storage surface 6 liberated thread turns forms. The support A substantially diametrically opposite a counter surface 16 is assigned. This begins at the outer diameter of the storage surface 6 or slightly further inward, and deviates in the withdrawal direction W obliquely, here upwards, back.

In Fig. 1 ist der Verlängerungsteil V beispielsweise ein einfacher Stab 8, oder eine Klinge 9, deren Rücken die Auflage A definiert. Der Verlängerungsteil V ist asymmetrisch zur Achse X und so ausgebildet, dass er beim Freisetzen jeder Fadenwindung über das Frontende 5 des Speicherkörpers K hinweg auf der Auflage A von der Fadenwindung kontaktiert wird. Unterseitig wird die Speicherfläche 6 über das Frontende 5 hinaus von einer beispielsweise ebenen oder konkaven Führungsfläche 22 (gestrichelt gezeigt) verlängert, während oberseitig stromab des Frontendes 5 eine Abdeckfläche 23 vorgesehen sein kann.In Fig. 1 is the extension part V, for example, a simple rod 8, or a blade 9, whose back defines the support A. The extension part V is asymmetrical to the axis X and formed so that it is contacted upon the release of each thread winding over the front end 5 of the storage body K away on the support A of the thread winding. On the underside, the storage surface 6 is extended beyond the front end 5 by an example flat or concave guide surface 22 (shown in phantom), while the top side downstream of the front end 5, a cover 23 may be provided.

In Fig. 2 ist der Verlängerungsteil V am Speicherkörper K ein schiefer Kegel 10 oder ein schiefer Kegelstumpf 11, der so angeordnet ist, dass die Auflage A im Wesentlichen in Abzugsrichtung W die Speicherfläche 6 an einer obenliegenden Position verlängert. Der Kegel 10 bzw. der Kegelstumpf 11 könnte einen allseits geschlossenen Mantel besitzen, oder aus einzelnen Stäben gebildet sein. Der Kegel bzw. Kegelstumpf 10, 11 hat eine Basis 12, deren Durchmesser ggfs. kleiner ist als der Durchmesser des Frontendes 5, wobei jedoch zwischen der Speicherfläche 6 und der Auflage A kein Übergang vorliegen sollte. Die Basis 12 muss nicht notwendigerweise kreisförmig sein, sondern könnte auch oval oder mit einer anderen Kontur ausgebildet werden. Die Unterseite des Kegels oder Kegelstumpfs bildet die Gegenfläche 16.In Fig. 2 the extension part V on the storage body K is a slanted cone 10 or a slanted truncated cone 11, which is arranged so that the support A extends substantially in the withdrawal direction W, the storage area 6 at an overhead position. The cone 10 or the truncated cone 11 could have a jacket which is closed on all sides, or be formed from individual rods. The cone or truncated cone 10, 11 has a base 12 whose diameter is possibly smaller than the diameter of the front end 5, but no transition should exist between the storage surface 6 and the support A. The base 12 does not necessarily have to be circular, but could also be oval or contoured. The underside of the cone or truncated cone forms the counter surface 16.

In Fig. 3 ist der Verlängerungsteil V am Speicherkörper K eine Klinge 17, die als Auflage A eine Flachseite oder konvex gerundete Flachseite 13 bildet. Die Auflage A endet mit einem stärker in Richtung zur Achse X abfallenden Endabschnitt 14, der bis zu einem Spitzenbereich 15 führt, der gegebenenfalls gerundet oder stumpf ist. Eine untere Schmalseite der Klinge 17 definiert die Gegenfläche 16, die in Abzugsrichtung W schräg oder konvex oder konkav gerundet zum Spitzenbereich 15 ansteigt.In Fig. 3 the extension part V on the storage body K is a blade 17, which forms a flat side or convexly rounded flat side 13 as a support A. The support A ends with a more towards the axis X sloping end portion 14, which leads to a tip portion 15, which is optionally rounded or dull. A lower narrow side of the blade 17 defines the mating surface 16, which increases in the withdrawal direction W obliquely or convexly or concavely rounded to the tip portion 15.

In dem Fadenmessliefergerät F von Fig. 4 besteht der Speicherkörper K aus in Umfangsrichtung mit Zwischenabständen um die Achse verteilten Fingern 18, die frei enden, und mit ihren Außenflächen 19 eine polygonartige Speicherfläche 6 definieren. Der Durchmesser der Speicherfläche, definiert durch die Finger 18, ist relativ klein, beispielsweise annähernd entsprechend der natürlichen Krümmungsspeicherfähigkeit der meisten Fadenmaterialien, und beträgt beispielsweise nur zwischen 25 und 50 mm.In the Fadenmessliefergerät F of Fig. 4 the storage body K consists of circumferentially spaced-apart fingers 18 distributed around the axis, which terminate freely, and define with their outer surfaces 19 a polygonal storage surface 6. The diameter of the storage area defined by the fingers 18 is relatively small, for example, approximately corresponding to the natural curvature storage capability most thread materials, and is for example only between 25 and 50 mm.

Der Verlängerungsteil V ist hier ein Hohlkörper (oder Massivkörper) mit annähernd rechteckigem Querschnitt und unteren und oberen Schmalseiten, wobei die obere Schmalseite die Auflage A definiert, die den in Bezug auf die Richtung der Gravitation obersten Finger 18 verlängert, und, zweckmäßig zumindest in etwa so breit ist wie die Außenfläche 19 dieses Fingers 18. An die Auflage A, die entweder parallel zur Achse X verläuft oder gerade oder gekrümmt etwas in Richtung zur Achse X abfällt, gegebenenfalls wie auch die Außenflächen 19 der Finger 18, wird durch den Endabschnitt 14 fortgesetzt, der steiler zu dem hier stumpfen Spitzenbereich 15 abfällt. Der Spitzenbereich 15 liegt z.B. in etwa in Verlängerung der Achse X des Speicherkörpers K. Der Hohlkörper (oder Massivkörper) 20 hat bei der gezeigten Ausführungsform flache Breitseiten. Bei einem ovalen Querschnitt wären die Breitseiten konvex gekrümmt. Die untere Schmalseite bildet die Gegenfläche 16 und steigt relativ steil zum Spitzenbereich 15 an. Der Hohlkörper 20 kann mit dem Finger 18 einstückig ausgebildet oder austauschbar an diesem angebracht sein. Eine zusätzliche Abstützung 21 kann im Bereich des unteren Endes der unteren Schmalseite 16 an einem unten liegenden Finger 18 oder am Speicherkörper K vorgesehen sein, um den Verlängerungsteil stabil abzustützen. Bei der gezeigten Ausführungsform ist die zusätzliche Befestigung 21 des Verlängerungsteil V bei dem unteren Finger 18' vorgesehen, mit dem der in Fig. 4 nicht hervorgehobene Stoppstift 3 (s. Fig. 1) zusammenarbeitet. Eine stromab des Speicherkörpers K gezeigte Platte kann zum Montieren etwa der gesteuerten Fadenklemme C von Fig. 1 dienen, oder zum Anbringen weiterer Ausstattungskomponenten oder Sensoren, und bildet auch eine äußere Führungsfläche 22 für die vom Speicherkörper K abgeschobenen Fadenwindungen.The extension part V is here a hollow body (or solid body) with approximately rectangular cross section and lower and upper narrow sides, wherein the upper narrow side defines the support A, which extends the uppermost with respect to the direction of gravity finger 18, and, suitably at least approximately As far as the outer surface 19 of this finger is 18. The support A, which is either parallel to the axis X or straight or curved something in the direction of the axis X drops, optionally as well as the outer surfaces 19 of the fingers 18, through the end portion 14th continued, which falls steeper to the blunt tip area 15 here. The tip region 15 is, for example, approximately in extension of the axis X of the storage body K. The hollow body (or solid body) 20 has flat broad sides in the embodiment shown. In the case of an oval cross section, the broad sides would be convexly curved. The lower narrow side forms the counter surface 16 and rises relatively steeply to the tip region 15. The hollow body 20 may be formed integrally with the finger 18 or be mounted exchangeably on this. An additional support 21 may be provided in the region of the lower end of the lower narrow side 16 on a lower finger 18 or on the storage body K in order to stably support the extension part. In the embodiment shown, the additional attachment 21 of the extension part V is provided at the lower finger 18 ', with which the in Fig. 4 not highlighted stop pin 3 (s. Fig. 1 ) works together. A plate shown downstream of the storage body K can be mounted for about the controlled thread clamp C of Fig. 1 serve, or for attaching further equipment components or sensors, and also forms an outer guide surface 22 for the depressed from the storage body K thread turns.

Obwohl dies nicht zwingend erforderlich ist, wird das Aufwickelelement 2 kontinuierlich angetrieben, gegebenenfalls mit variierender Geschwindigkeit, so dass fortlaufend neue Fadenwindungen auf der Speicherfläche K gebildet und bei zurückgezogenem Stoppstift 3 in Abzugsrichtung W vorne liegende Fadenwindungen auf die Auflage A transportiert werden, während der stromab verlaufende Schussfadenabschnitt noch von der Fadenklemme C festgehalten ist. Nach Öffnen der Fadenklemme C werden die Fadenwindungen von der Auflage A aufeinanderfolgend konsumiert, wobei der Stoppstift 3 dann oder bereits vorher seine Endposition im Führungsschlitz 4 erreicht hat. Die letzte, bis zum Stoppstift 3 verlaufende Fadenwindung an der in Abzugsrichtung liegenden Seite des Stoppstiftes 3 wird vom Verlängerungsteil V abgezogen und erstreckt sich schließlich, nachdem der Eintragvorgang vom Stoppstift 3 beendet wurde, im Wesentlichen gerade vor der Fadenklemme C zum Stoppstift 3.Although this is not absolutely necessary, the winding element 2 is driven continuously, possibly with varying speed, so that continuously new turns of thread formed on the storage surface K and with retracted stop pin 3 in the withdrawal direction W front yarn turns are transported to the support A, while the downstream extending weft thread portion is still held by the thread clamp C. After opening the thread clamp C the thread turns of the rest A consumed sequentially, the stop pin 3 then or has previously reached its final position in the guide slot 4. The last thread winding running up to the stop pin 3 on the side of the stop pin 3 lying in the withdrawal direction is withdrawn from the extension part V and finally, after the insertion process has been completed by the stop pin 3, extends substantially straight ahead of the thread clamp C to the stop pin 3.

Danach klemmt die Fadenklemme C den Schussfaden erneut fest. Der Stoppstift 3 wird zurückgezogen, entgegen der Abzugsrichtung W zum Aufwickelelement 2 bewegt und erneut zwischen zwei Windungen eingeschoben, ehe ihn die nachfolgend gebildeten Fadenwindungen wieder bis in die Endposition verlagern.Thereafter, the thread clamp C clamps the weft again. The stop pin 3 is withdrawn, moved against the take-off direction W to the take-up element 2 and inserted again between two turns before it again shift the thread turns formed up to the end position.

Da die Führungsfläche 22 die abgeschobenen Fadenwindungen von unten abstützt, könnte der Verlängerungsteil V auch z.B. in der 9-Uhr-Position oder an anderer Stelle, d.h. nicht in der gezeigten 12-Uhr-Position, angeordnet sein.Since the guide surface 22 supports the deported turns of thread from below, the extension part V could also be e.g. at the 9 o'clock position or elsewhere, i. not in the 12 o'clock position shown.

Die Ausführungsform in Fig. 5 zeichnet sich durch einen besonders einfachen Verlängerungskörper V in Form eines im Wesentlichen rechtwinkligen Dreiecks 24 auf, dessen eine Kathete die Auflage A definiert, während die Hypotenuse die schräg ansteigende Gegenfläche bildet. Dieses Dreieck könnte eine flächige dreieckige Klinge sein, wie gezeigt, oder aus einem Stab 8 und einem anderen, die Gegenfläche 16 definierenden Stab bestehen, die zweckmäßig in einem Spitzenbereich miteinander verbunden sind.The embodiment in Fig. 5 is characterized by a particularly simple extension body V in the form of a substantially right triangle 24, one of the cathodes defines the support A, while the hypotenuse forms the inclined rising counter surface. This triangle could be a flat triangular blade, as shown, or consist of a rod 8 and another rod defining the mating surface 16, suitably connected together in a tip region.

Auch die Ausführungsform in Fig. 6 verwendet einen im Wesentlichen dreieckigen Verlängerungsteil V ähnlich dem von Fig. 5, wobei jedoch wegen der untenliegenden Führungsfläche 22 die Auflage A in der 9-Uhr-Position und die Gegenfläche 16 in der 3-Uhr-Position angeordnet sind.Also, the embodiment in Fig. 6 uses a substantially triangular extension part V similar to that of FIG Fig. 5 However, because of the underlying guide surface 22, the support A in the 9 o'clock position and the counter surface 16 are arranged in the 3 o'clock position.

In der Ausführungsform in Fig. 7 (Seitenansicht) ist eine besonders zweckmäßig Ausführungsform des Verlängerungsteils V am Speicherkörper K gezeigt. Die im Wesentlichen gerade Auflage A, die die Speicherfläche des Speicherkörpers verlängert, führt über einen stärker abgeschrägten Endabschnitt 15 zum Spitzenbereich 15. Auch die Gegenfläche 16 hat einen Endabschnitt 25, der mit weniger Neigung als die Gegenfläche 16 nahezu parallel zur Achse X des Speicherkörpers K verläuft und beim Spitzenbereich 15 endet. Dieser Endabschnitt 25 trägt dazu bei, die Neigung der Fadenwindungen, beim Abzug von der Auflage A aufzusteigen, zu unterdrücken.In the embodiment in FIG Fig. 7 (Side view) is a particularly expedient embodiment of the extension part V on the storage body K shown. The essentially straight support A, which extends the storage surface of the storage body, leads via a more bevelled end section 15 to the tip region 15 Counter surface 16 has an end portion 25 which extends with less inclination than the counter surface 16 almost parallel to the axis X of the storage body K and ends at the tip portion 15. This end portion 25 helps to suppress the tendency of the turns of thread to ascend upon withdrawal from the overlay A.

Im Kern besteht die Erfindung darin, den Speicherkörper des Fadenmessliefergerätes, das optimal hohe Schussfrequenzen und Schussgeschwindigkeiten ermöglichen soll, mit einem Verlängerungsteil zu versehen, der nur gerade so viel störenden Einfluss auf den Fadenabzug nimmt, dass die Schussfrequenz und Schussgeschwindigkeit nicht spürbar beeinträchtigt wird, die mit diesem Konzept des Fadenmessliefergerätes möglich sind, der jedoch sicherstellt, dass nicht zwei Fadenwindungen aneinander hängen bleiben und Schlingen bilden können. Die Einflussnahme des Verlängerungsteils beschränkt sich im Wesentlichen nur auf eine lokale Stelle in der 360°-Erstreckung jeder Fadenwindung, an der die Fadenwindung nicht direkt nach innen in Verlängerung der Achse des Speicherkörpers weggezogen werden kann, was bewirkt, dass die Fadenwindungen in der rohrförmigen Konfiguration des freigesetzten Fadenwindungswickels zuverlässig voneinander separiert und schlingenfrei eingetragen werden. Die in Abzugsrichtung gesehene Länge der Auflage des Verlängerungsteils richtet sich nach dem Fadendurchmesser und kann, beispielsweise, in etwa der Länge der Speicherfläche des Speicherkörpers entsprechen. Die das Festziehen von Fadenwindungen am Verlängerungsteil ausschließende Gegenfläche kann an ihrem Beginn am Speicherkörper so gestaltet werden, dass sie Platz für dort benötigte Fadensteuerorgane freilässt.In essence, the invention consists in providing the storage body of the Fadenmessliefergerätes that should allow optimal high firing rates and firing speeds, with an extension part that only just so much disturbing influence on the thread takeoff that the firing frequency and firing speed is not appreciably affected, the are possible with this concept of Fadenmessliefergerätes, however, ensures that not two thread turns hang each other and can form loops. The influence of the extension member is essentially limited only to a local location in the 360 ° extension of each thread turn where the thread winding can not be pulled away directly inwardly in extension of the axis of the storage body, causing the thread turns in the tubular configuration the released Fadenwindungswickels reliably separated from each other and entered loop-free. The length seen in the withdrawal direction of the support of the extension part depends on the thread diameter and can, for example, correspond approximately to the length of the storage surface of the storage body. The tightening of turns of thread on the extension part excluding mating surface can be designed at its beginning on the storage body so that it leaves room for thread control organs required there.

Die Fig. 8, 9 und 10 zeigen eine konkrete Ausführungsform eines Messliefergeräts F mit körperlicher Ausbildung der in Fig. 1 nur schematisch angedeuteten äußeren Abdeckfläche 23. Am Gehäuse 1 ist eine auslegerartige Stütze 28 mit einer Halterung 27 festgelegt. In der Stütze 28 ist eine Blattfeder 29 enthalten, die mit ihrer Unterseite die äußere Abdeckfläche 23 bildet.The FIGS. 8, 9 and 10 show a concrete embodiment of a measuring delivery device F with physical training of in Fig. 1 only schematically indicated outer cover surface 23. On the housing 1, a cantilevered support 28 is fixed with a holder 27. In the support 28, a leaf spring 29 is included, which forms the outer cover surface 23 with its underside.

Entsprechend den Fig. 8, 9 und 10 ist die Blattfeder 29 über wenigstens einen Federkörper 30 in der Stütze 28 gehalten, und zwar so, dass der Federkörper 30 eine seitlich zur Auflage A und der Außenseite 19 des Fingers 18 versetzte Kippachse definiert, die in etwa parallel zur Achse des Speicherkörpers K verläuft. Die Blattfeder 29 wird gegebenenfalls leicht gegen die Auflagefläche 19 des Fingers 18 und die Auflage A des Verlängerungsteils V angedrückt, so dass sie in Richtung des Doppelpfeils 31 federnd bewegt ist. Die Blattfeder 29 beginnt in Abzugsrichtung W im Abstand vom Aufwickelelement 2 (Fig. 10) und erstreckt sich über das Ende der Auflage A hinaus und definiert mit der Auflagefläche 19 und der Auflage A einen längsverlaufenden Fadenwindungskontrollspalt. Zumindest an dem dem Aufwickelelement 2 zugewandten Ende weist die Blattfeder 29 eine vom Speicherkörper K weg weisende Aufbiegung 32 auf.According to the FIGS. 8, 9 and 10 the leaf spring 29 is held in the support 28 via at least one spring body 30, in such a way that the spring body 30 defines a tilting axis offset laterally relative to the support A and the outside 19 of the finger 18, which runs approximately parallel to the axis of the storage body K. The leaf spring 29 is optionally lightly pressed against the support surface 19 of the finger 18 and the support A of the extension part V, so that it is resiliently moved in the direction of the double arrow 31. The leaf spring 29 begins in the withdrawal direction W at a distance from the take-up 2 ( Fig. 10 ) and extends beyond the end of the support A and defines with the support surface 19 and the support A a longitudinal Fadenwindungskontrollspalt. At least at the end facing the winding element 2, the leaf spring 29 has a bend 32 pointing away from the storage body K.

Gemäß Fig. 10 ist der Verlängerungsteil V einstückig oder übergangslos mit dem Finger 18 ausgebildet. Die von beispielsweise der Blattfeder 29 gebildete Abdeckfläche 23 könnte auch in geringem Abstand von der Auflagefläche 19 und der Auflage A gehaltert sein, vorausgesetzt, dass sie im Betrieb des Messliefergeräts F die Fadenwindungen geringfügig beaufschlagt und sicherstellt, dass die Fadenwindungen nicht übereinander geschoben werden können und beim Abzug von der Auflage A nicht hochsteigen.According to Fig. 10 is the extension part V integrally or seamlessly formed with the finger 18. The cover surface 23 formed by, for example, the leaf spring 29 could also be held at a small distance from the support surface 19 and the support A, provided that it slightly impinges the yarn turns during operation of the measuring delivery device F and ensures that the turns of thread can not be pushed over each other and do not climb when deducting from the overlay A.
