Definitions
- the invention relates to a latch needle for a stitch-forming machine, in particular for a knitting machine for producing textile surfaces.
- latch needles are used in machines, in particular in knitting machines, which are moved back and forth in rapid succession during operation.
- the provided on such a latch needle tongue opens and closes in rapid succession and at high speed a receiving space for the thread.
- the tongue head When changing the tongue from closed position to reserve describes the tongue head a circular arc-shaped swinging motion.
- the tongue beats in rapid succession alternately on the hook to form the closed position and on the Shaft of the latch needle, to form the open position or reserve.
- the receiving space of the thread is bounded by a needle body and its one-end hook in cooperation with the opening and closing tongue.
- tongue-glazed needles are used to form the stitch
- the tip of the hook plunges into a depression in the tongue head.
- the tip of the hook is almost completely covered by the tongue head. This facilitates the knocking off of half stitches over the tongue head and thus the stitch formation.
- knocking off the semi-mesh slides from the top of the needle over the tongue shaft and then over the tongue head.
- the relatively wide tongue head facilitates the interaction of tongue and hook by the tongue head hits the hook safely even with greater tongue bearing tolerance.
- the latch needles are slidably held in a needle carrier while being reciprocated in the longitudinal direction by cams for loop formation.
- the shaft width of a latch needle is slightly smaller than the width of a needle channel associated with it. Due to the existing manufacturing tolerance of the needle channels and the needle shank width, it is possible that a latch needle, influenced by the rotation of the needle carrier of a circular knitting machine, with respect to the center axis of a guide channel, inclined thereto.
- the knitting machine needle and its tongue each undergo a deflection relative to their ideal position. These tolerances increase due to wear with increasing duration of use of the knitting needle, with the result that also increases the lateral deflection of the tongue.
- knitting machines which have little space between the needles and boards for the passage of the tongue in their swinging motion, it may thus lead to contact between the tongue head and a board adjacent to him. Both the board and the tongue head experience wear, which is disadvantageous.
- hook-pointed latch needles have been proposed. So revealed the DE OS 28 34 558 a knitting needle whose hook has a relatively deep trough in the area of the tip. This trough receives a portion of the tongue spoon, being bounded by two side surfaces arranged at an acute angle to each other, which partially overlap the tongue spoon of the tongue when the tongue is in the closed position.
- the width of the tongue is less than the width of the hook and thus substantially less than the width of the needle shank.
- this has the consequence that the half-stitch during stripping on the part of the hook tip, which is not covered by the tongue head, strips and gets stuck in the worst case, whereby the tee-off process is interrupted. This in turn has a negative effect on the stitch formation.
- a solution for this will be in the DE 100 57 765 disclosed.
- This solution is used in many cases, with the increased due to the projection increased mass of the tongue, especially in high-speed knitting machines, as disadvantageous.
- an object of the invention to provide an improved latch needle for a stitch-forming machine having a tongue with a tongue shaft which is pivotally mounted on a bearing means and carries a tongue head, which is provided with a receiving space for receiving the tip of the hook.
- Such needles are in the WO 02/08506 A , of the US 3,728,874 A or the EP 0 077 022 A shown graphically with a width of the tongue head, which is smaller than the width of the needle shaft.
- latch needle which has the smallest possible tongue spoon whose tongue head has a width smaller than 95% of the width of the needle shank. This allows the half-stitch to experience minimal expansion when knocked off as it slides over the relatively narrow tongue head.
- the distance to the adjacent part (board) due to the reduced compared to known latch needles width of the tongue head, the distance to the adjacent part (board) and thus reduces the risk of contact between the board and the tongue head.
- the formation of sharp-edged edges on the tongue head is avoided. There are no sharp edges that could damage threads used to form stitches. In particular, the otherwise possible worst case severing of filaments, i. the generation of a faulty goods, with appropriate fault lines avoided.
- the latch needle according to the invention combines the advantages of the hook-toothed needle with the advantages of the tongue-stained needle.
- the latch needle according to the invention has a tongue whose tongue head is delimited by two surface areas arranged parallel to one another, in the form of facets. The distance of these side surfaces forms the width of the tongue head.
- the side surfaces are arranged in parallel to an imaginary by the central axis of the tongue or the knitting machine needle level extending in the tongue longitudinal direction.
- the transition of the side surfaces in the tongue head back is edge-free, ie formed rounded. This ensures a smooth sliding of the half stitch over the closed tongue back.
- Opposite the back of the Tongue's head is formed a hollow, a so-called Zasche.
- This zipper receives at least a portion of the tip of the hook of the latch needle and is preferably adapted to its geometry.
- the zapping of the tongue head is a Image, for example, in the sense of an inverse or negative shape of the tip of the hook.
- the transition from the relatively narrow tongue shaft to the tongue head is formed by two facets. These are arranged divergently in the tongue longitudinal direction as in a conventional latch needle. In addition, further facets may be arranged at the transition region from the tongue shaft to the tongue head, which allow a special design of a receiving hopper in the tongue shaft.
- the tongue shaft is limited in its width by two side surfaces which are oriented parallel to each other.
- the tongue shaft is mounted on a bearing device in the tongue slot of the knitting machine needle.
- This bearing device may be formed as a separate axle by means of an axle pin or as a pin or half-pin, which is formed from the sheep cheeks. So that the necessary ease of the tongue is ensured in the tongue slot, the side surfaces of the tongue shaft can be arranged at an acute angle to each other in the direction of the tongue.
- the tongue shaft can thus be slightly wedge-shaped. Its width then decreases in the direction of the tongue-head. The reduction of the width is limited to a few thousandths of a millimeter.
- the side surfaces of the tongue shaft are then arranged at an acute angle to each other, wherein the opening direction of the angle is oriented away from the tongue head.
- the side surfaces of the tongue head are arranged only in the vertical direction parallel to the side surfaces of the tongue shaft.
- the imaginary extension of the side surface of the tongue head then forms with the adjacent side surface of the tongue shaft, an acute angle greater than zero degrees.
- the opening direction of the angle is oriented in the direction of the tongue head.
- the side surface of the tongue head encloses an obtuse angle smaller than 180 ° with the side surface of the tongue shaft.
- the tongue slot in which the tongue shaft is movably mounted, is arranged in the longitudinal direction of the knitting machine needle and is preferably located in the center of the needle shaft with respect to the needle width, which is measured in the needle transverse direction. It is bounded by two mutually facing side surfaces which are formed on the shaft walls of the needle shaft and between which the slot width is to be measured. Between the shaft walls of the tongue slot is arranged.
- the width of the needle shank is measured perpendicular to its side surfaces. This shank width substantially coincides with the width of the needle receptacle in the knitting machine or is slightly smaller, so that the longitudinal displacement of the knitting machine needle is ensured.
- the width of the tongue head is preferably substantially smaller than the width of the needle shaft.
- the width of the latch head is 80% of the width of the needle shank, with the reduction in travel already afforded by the reduction of 5% of the tab head width from the width of the needle shank.
- the tongue tongue width is between 70 and 90% of the width of the needle shank. This ensures that there is sufficient space between the side surface which delimits the tongue head and the part of a knitting machine adjacent to the side surface during the oscillating movement of the tongue.
- a tongue head according to the invention is due to its shape.
- the mutually parallel side surfaces of the tongue head provide in the case of contact with another part of a knitting machine a planar system. This is less susceptible to wear compared to a punctiform contact point and any wear is less. Thus, the risk that sharp edges arise in the area of the tongue head is considerably reduced.
- the needle hook has a tapered tip. This is formed in the shape of a tapered cone. This cone tapers from the hook cross section to the tip. The tip is rounded so that contact with the thread on the latter leaves no damage.
- FIG. 1 a latch needle 1 is illustrated, which has a needle body 2 with a stitch-forming part 3 at the end a hook 4 is formed.
- the hook 4 ends in a tip 14.

- the storage device 6 is z. B. formed by a tongue slot 5 by cross-bearing axis. This bearing axis may be formed in the form of a bearing pin or preferably in the form of a one-piece or multi-part with the needle body 2 seamlessly connected pin.
- To this storage device 6 is the tongue 7, from the in FIG. 1 Closing position illustrated on the left, in a reserve in FIG. 1 illustrated on the right side, hinged. When changing from the shooting position to the open position, a hook interior 10 is closed or opened.
- the tongue 7 has a narrow, preferably parallelflankig limited shaft 8, the width of which is slightly smaller than that of the tongue slot 5.
- the length of the tongue 7 is dimensioned so that it can reach the top of the hook 4 with its end 23 and partially overlaps ,
- the end 23 is provided on the hook 4 side facing a concave molding surface 25, according to the embodiment of FIG. 1 a trough 12 for receiving at least a portion of the hook 4 forms.
- the mold surface 25 may correspond to the shape of the top 17 of the hook tip 14 and be adapted.
- the overall configuration is such that the trough 12 exclusively a portion of the conical tip, but not other sections of the hook 4 receives.
- the formation of the end 23 of the tongue 7 is further from the Figures 2 . 3 and 4 out.
- the end 23 has a back surface 24, which forms the back of a end formed on the tongue 7 spoon. This spoon marks the end 23 of the tongue 7.
- Its width 16 exceeds the width BS of the substantially parallel flank tongue shaft 8 (FIG. FIG. 3 ).
- the tongue head width 16 is determined by the distance between a first side surface 21 and a second side surface 22 of the tongue head 9 and measured perpendicular to this. It exceeds the width BS of the tongue shaft 8.
- the width BS of the tongue shaft 8 which is measured perpendicular to the flat sides 27, 28, increases steadily in the transition region until the width 16 of the tongue head 9 is reached.
- the width BS of the tongue shaft 8 can be constant in the width 16 of the tongue head 9.
- an isosceles, preferably trapezoidal shaping surface 26 (on each side of the tongue shaft) 26 (FIG. FIG. 2 ) arise.
- the mold surface 26 may preferably be flat. It is also possible that it has a slight convex or concave curvature.
- the tongue head 9 has a smaller width than that in plan view FIG. 3 underneath part of the hook 4 or the needle shaft 20, the tongue 7 defines an outline which lies completely within the outline of the needle shaft 20.

- the side surface 21 and 22 respectively lies in a plane which is aligned parallel to another plane in which the side surface 27 or 28 of the tongue shaft 8 lies.
- the tongue head 9 has a trough or a receiving space 12, which, when the tongue 7 is in the closed position, at least part of the tip 14 of the hook 4 receives.
- the receiving space 12 and the hook tip 14 are adapted to each other so that the front portion of the hook tip 14 almost completely immersed in the receiving space 12. This makes it possible that a thread without obstacle in the hook interior 10, slides under the hook tip.
- the lower part of the hook tip 14 does not form, with respect to the lower edge of the tongue head 9, protruding edge when the tongue is in the closed position ( FIG. 2 ). This makes it possible that a thread can slide without resistance into the hook interior under the hook tip and does not get caught on one edge.
- the width 11 ( FIG. 3 ) of the needle shaft 20 extends between a first side surface 18 and a second side surface 19. It is equal to or slightly smaller than the width of the needle channel in which the tongue needle 1 is slidably mounted.

Description
Die Erfindung betrifft eine Zungennadel für eine maschenbildende Maschine, insbesondere für eine Strickmaschine zur Erzeugung textiler Flächen.The invention relates to a latch needle for a stitch-forming machine, in particular for a knitting machine for producing textile surfaces.
Zur Erzeugung von Maschen aus zumindest einem Faden werden in Maschinen, insbesondere in Strickmaschinen, so genannte Zungennadeln eingesetzt, die in Betrieb in schneller Folge hin- und herbewegt werden. Die an einer solchen Zungennadel vorgesehene Zunge öffnet und schließt dabei in rascher Folge und mit hoher Geschwindigkeit einen Aufnahmeraum für den Faden. Bei dem Wechsel der Zunge von Schließlage in Rücklage beschreibt der Zungenkopf eine kreisbogenförmige Schwingbewegung. Dabei schlägt die Zunge in rascher Folge abwechselnd auf den Haken zur Bildung der Schließlage sowie auf den Schaft der Zungennadel, zur Bildung der Offenlage bzw. Rücklage.To produce stitches from at least one thread, so-called latch needles are used in machines, in particular in knitting machines, which are moved back and forth in rapid succession during operation. The provided on such a latch needle tongue opens and closes in rapid succession and at high speed a receiving space for the thread. When changing the tongue from closed position to reserve describes the tongue head a circular arc-shaped swinging motion. The tongue beats in rapid succession alternately on the hook to form the closed position and on the Shaft of the latch needle, to form the open position or reserve.
Der Aufnahmeraum des Fadens wird von einem Nadelgrundkörper und dessen an einem Ende vorhandenen Haken in Zusammenwirkung mit der sich öffnenden und schließenden Zunge begrenzt. Werden zur Maschenbildung so genannte zungengezaschte Nadeln verwendet, taucht die Hakenspitze in eine Mulde im Zungenkopf ein. Durch die Aufnahme der Hakenspitze in der Mulde des Zungenkopfs ist sicher gestellt, dass die Hakenspitze von dem Zungenkopf nahezu vollständig abgedeckt wird. Dies erleichtert das Abschlagen von Halbmaschen über den Zungenkopf und somit die Maschenbildung. Beim Abschlagen gleitet die Halbmasche ausgehend von der Oberseite der Nadel über den Zungenschaft und anschließend über den Zungenkopf. Der relativ breite Zungenkopf erleichtert das Zusammenwirken von Zungenkopf und Haken, indem der Zungenkopf den Haken auch bei größerer Zungenlagertoleranz sicher trifft.The receiving space of the thread is bounded by a needle body and its one-end hook in cooperation with the opening and closing tongue. If so-called tongue-glazed needles are used to form the stitch, the tip of the hook plunges into a depression in the tongue head. By the inclusion of the hook tip in the trough of the tongue head is ensured that the tip of the hook is almost completely covered by the tongue head. This facilitates the knocking off of half stitches over the tongue head and thus the stitch formation. When knocking off the semi-mesh slides from the top of the needle over the tongue shaft and then over the tongue head. The relatively wide tongue head facilitates the interaction of tongue and hook by the tongue head hits the hook safely even with greater tongue bearing tolerance.
Die Zungennadeln sind in einem Nadelträger verschiebbar gehalten, wobei sie durch Nocken gesteuert zur Maschenbildung in Längsrichtung hin- und herbewegt werden. Um die schnelle Hin- und Herbewegung zu gewährleisten, ist die Schaftbreite einer Zungennadel geringfügig kleiner als die Weite eines ihr zugeordneten Nadelkanals. Aufgrund der vorhandenen Fertigungstoleranz der Nadelkanäle und der Nadelschaftbreite ist es möglich, dass eine Zungennadel, beeinflusst von der Rotation des Nadelträgers einer Rundstrickmaschine, in Bezug auf die Mittelachse eines Führungskanals, geneigt zu diesem liegt.The latch needles are slidably held in a needle carrier while being reciprocated in the longitudinal direction by cams for loop formation. To ensure fast back and forth movement, the shaft width of a latch needle is slightly smaller than the width of a needle channel associated with it. Due to the existing manufacturing tolerance of the needle channels and the needle shank width, it is possible that a latch needle, influenced by the rotation of the needle carrier of a circular knitting machine, with respect to the center axis of a guide channel, inclined thereto.
In einer Rundstrickmaschine sind mehrere, teilweise bis zu 6.000, Strickmaschinennadeln in geringem Abstand zueinander angeordnet. Zusätzlich befindet sich zwischen zwei Nadeln jeweils eine Platine, die für den Maschenbildungsprozess benötigt wird. Diese Platine unterstützt zum einen das so genannte Abschlagen der Maschen über die geschlossene Zunge sowie das Niederhalten der gestrickten Ware.In a circular knitting machine, several, sometimes up to 6,000, knitting machine needles are in close proximity to each other arranged. In addition, there is a board between two needles, which is needed for the stitch formation process. This board supports on the one hand the so-called knocking off of the stitches over the closed tongue as well as the holding down of the knitted goods.
Aufgrund der Toleranz im Führungskanal des Nadelbetts und der Toleranz im Bereich der Zungenlagerung erfahren die Strickmaschinennadel und deren Zunge jeweils eine Auslenkung gegenüber ihrer Idealposition. Diese Toleranzen vergrößern sich, aufgrund von Verschleiß mit zunehmender Einsatzdauer der Strickmaschinenadel, was zur Folge hat, dass sich auch die seitliche Auslenkung der Zunge vergrößert. Bei Strickmaschinen, die zwischen den Nadeln und Platinen wenig Zwischenraum für den Durchgang der Zunge bei ihrer Schwingbewegung aufweisen, kann es somit zu Berührungen zwischen dem Zungenkopf und einer ihm benachbarten Platine führen. Dabei erfahren sowohl die Platine als auch der Zungenkopf einen Verschleiß, was nachteilig ist.Due to the tolerance in the guide channel of the needle bed and the tolerance in the area of the tongue bearing, the knitting machine needle and its tongue each undergo a deflection relative to their ideal position. These tolerances increase due to wear with increasing duration of use of the knitting needle, with the result that also increases the lateral deflection of the tongue. In knitting machines, which have little space between the needles and boards for the passage of the tongue in their swinging motion, it may thus lead to contact between the tongue head and a board adjacent to him. Both the board and the tongue head experience wear, which is disadvantageous.
Um dies zu vermeiden wurden so genannte hakengezaschte Zungennadeln vorgeschlagen. So offenbart die
Ein weiterer Nachteil einer hakengezaschten Nadel besteht darin, dass der relativ schmale Zungenkopf dazu neigt, seitlich am Haken vorbei in den Hakeninnenraum zu gleiten. Diese Gefahr erhöht sich mit zunehmendem Verschleiß der Zungenlagerung.Another disadvantage of a hooked-on needle is that the relatively narrow tongue head tends to slide laterally past the hook into the hook interior. This danger increases with increasing wear of the tongue bearing.
Ein zusätzlicher Nachteil einer hakengezaschten Nadel ist, dass der Übergang von der Zungenschaftinnenseite zur Hakenspitze, wenn sich die Zunge in Schließlage befindet, nicht stufenlos ausgebildet ist. Dies erhöht die Gefahr, dass insbesondere beim Plattieren, d.h. beim Stricken mit zwei Fäden, einer dieser beiden Fäden zwischen der geschlossenen Zunge und dem Haken entweicht. Es entsteht fehlerhafte Ware.An additional disadvantage of a hook-pointed needle is that the transition from the tongue shaft inner side to the hook tip, when the tongue is in the closed position, is not continuously formed. This increases the risk that, in particular during plating, i. when knitting with two threads, one of these two threads escapes between the closed tongue and the hook. It creates faulty goods.
Eine Lösung dafür wird in der
Auch die
Davon ausgehend ist es Aufgabe der Erfindung, eine verbesserte Zungennadel für eine maschenbildende Maschine anzugeben, welche eine Zunge mit einem Zungenschaft aufweist, der an einer Lagereinrichtung schwenkbar gelagert ist und einen Zungenkopf trägt, der mit einem Aufnahmeraum zur Aufnahme der Spitze des Hakens versehen ist.On this basis, it is an object of the invention to provide an improved latch needle for a stitch-forming machine having a tongue with a tongue shaft which is pivotally mounted on a bearing means and carries a tongue head, which is provided with a receiving space for receiving the tip of the hook.
Derartige Nadeln werden in der
Diese Aufgabe wird gemäß Anspruch 1 mit einer Zungennadel gelöst, die einen möglichst schmalen Zungenlöffel aufweist dessen Zungenkopf eine Breite kleiner als 95% der Breite des Nadelschaftes aufweist. Dies ermöglicht, dass die Halbmasche beim Abschlagen, wenn sie über den relativ schmalen Zungenkopf gleitet, eine allenfalls geringe Aufweitung erfährt. Außerdem ist aufgrund der gegenüber bekannten Zungennadeln verminderten Breite des Zungenkopfes der Abstand zum benachbarten Teil (Platine) und somit die Gefahr der Berührung zwischen Platine und Zungenkopf reduziert. Die Entstehung scharfkantiger Ränder am Zungenkopf wird vermieden. Es entstehen keine scharfen Kanten, die Fäden, die zur Maschenbildung benutzt werden, beschädigen könnten. Insbesondere wird die sonst im schlimmsten Fall mögliche Durchtrennung von Fäden, d.h. die Erzeugung einer fehlerhaften Ware, mit entsprechenden Fehlerlinien vermieden. Die erfindungsgemäße Zungennadel vereint die Vorteile der hakengezaschten Nadel mit den Vorteilen der zungengezaschten Nadel.This object is achieved according to
Die erfindungsgemäße Zungennadel weist eine Zunge auf, deren Zungenkopf durch zwei flächenparallel zueinander angeordneten Seitenflächen, in Form von Facetten, begrenzt wird. Der Abstand dieser Seitenflächen bildet die Breite des Zungenkopfs. Die Seitenflächen sind zu einer durch die Mittelachse der Zunge bzw. der Strickmaschinennadel gedachten Ebene parallel angeordnet die in Zungenlängsrichtung verläuft. Der Übergang der Seitenflächen in den Zungenkopfrücken ist kantenfrei, d.h. gerundet ausgebildet. Dadurch wird ein sanftes Gleiten der Halbmasche über den geschlossenen Zungenrücken sichergestellt. Gegenüber dem Rücken des Zungenkopfs ist eine Mulde, eine so genannte Zasche ausgebildet. Diese Zasche nimmt zumindest einen Teil der Spitze des Hakens der Zungennadel auf und ist vorzugsweise an dessen Geometrie angepasst. Im Idealzustand ist die Zasche des Zungenkopfs ein Abbild zum Beispiel im Sinne einer Invers- oder Negativform der Spitze des Hakens.The latch needle according to the invention has a tongue whose tongue head is delimited by two surface areas arranged parallel to one another, in the form of facets. The distance of these side surfaces forms the width of the tongue head. The side surfaces are arranged in parallel to an imaginary by the central axis of the tongue or the knitting machine needle level extending in the tongue longitudinal direction. The transition of the side surfaces in the tongue head back is edge-free, ie formed rounded. This ensures a smooth sliding of the half stitch over the closed tongue back. Opposite the back of the Tongue's head is formed a hollow, a so-called Zasche. This zipper receives at least a portion of the tip of the hook of the latch needle and is preferably adapted to its geometry. Ideally, the zapping of the tongue head is a Image, for example, in the sense of an inverse or negative shape of the tip of the hook.
Der Übergang von dem relativ schmalen Zungenschaft zu dem Zungenkopf wird durch zwei Facetten gebildet. Diese sind wie bei einer herkömmlichen Zungennadel in Zungenlängsrichtung divergierend angeordnet. Zusätzlich können an dem Übergangsbereich von dem Zungenschaft zu dem Zungenkopf weitere Facetten angeordnet sein, die eine besondere Ausbildung eines Aufnahmetrichters in dem Zungenschaft erlauben.The transition from the relatively narrow tongue shaft to the tongue head is formed by two facets. These are arranged divergently in the tongue longitudinal direction as in a conventional latch needle. In addition, further facets may be arranged at the transition region from the tongue shaft to the tongue head, which allow a special design of a receiving hopper in the tongue shaft.
Der Zungenschaft wird in seiner Breite durch zwei Seitenflächen begrenzt, die parallel zueinander orientiert sind. Der Zungenschaft ist an einer Lagereinrichtung im Zungenschlitz der Strickmaschinennadel gelagert. Diese Lagereinrichtung kann als separate Achse mittels eines Achsstifts oder als Zapfen bzw. Halbzapfen, der aus den Schaftwangen gebildet wird, ausgebildet sein. Damit die notwendige Leichtgängigkeit der Zunge in dem Zungenschlitz gewährleistet ist, können die Seitenflächen des Zungenschafts in Richtung Zungenkopf spitzwinkelig zueinander angeordnet sein. Der Zungenschaft kann somit etwas keilförmig ausgebildet sein. Seine Breite nimmt dann in Richtung des Zungenkopfs ab. Dabei ist die Reduzierung der Breite auf wenige Tausendstel mm begrenzt. Die Seitenflächen des Zungenschafts sind dann in einem spitzen Winkel zueinander angeordnet, wobei die Öffnungsrichtung des Winkels von dem Zungenkopf weg orientiert ist. Bei einer Zunge mit einem sich verjüngenden Zungenschaft sind die Seitenflächen des Zungenkopfs nur in vertikaler Richtung parallel zu den Seitenflächen des Zungenschafts angeordnet. Die gedachte Verlängerung der Seitenfläche des Zungenkopfs bildet dann mit der ihr benachbarten Seitenfläche des Zungenschafts, einen spitzen Winkel größer Null Grad. Die Öffnungsrichtung des Winkels ist in Richtung des Zungenkopfs orientiert. Mit anderen Worten, die Seitenfläche des Zungenkopfs schließt mit der Seitenfläche des Zungenschafts einen stumpfen Winkel kleiner 180° ein.The tongue shaft is limited in its width by two side surfaces which are oriented parallel to each other. The tongue shaft is mounted on a bearing device in the tongue slot of the knitting machine needle. This bearing device may be formed as a separate axle by means of an axle pin or as a pin or half-pin, which is formed from the sheep cheeks. So that the necessary ease of the tongue is ensured in the tongue slot, the side surfaces of the tongue shaft can be arranged at an acute angle to each other in the direction of the tongue. The tongue shaft can thus be slightly wedge-shaped. Its width then decreases in the direction of the tongue-head. The reduction of the width is limited to a few thousandths of a millimeter. The side surfaces of the tongue shaft are then arranged at an acute angle to each other, wherein the opening direction of the angle is oriented away from the tongue head. In a tongue with a tapered tongue shaft, the side surfaces of the tongue head are arranged only in the vertical direction parallel to the side surfaces of the tongue shaft. The imaginary extension of the side surface of the tongue head then forms with the adjacent side surface of the tongue shaft, an acute angle greater than zero degrees. The opening direction of the angle is oriented in the direction of the tongue head. In other words, the side surface of the tongue head encloses an obtuse angle smaller than 180 ° with the side surface of the tongue shaft.
Der Zungenschlitz, in dem der Zungenschaft bewegbar befestigt ist, ist in Längsrichtung der Strickmaschinennadel angeordnet und liegt vorzugsweise in der Mitte des Nadelschafts in Bezug auf die Nadelbreite, die in Nadelquerrichtung gemessen wird. Er wird von zwei aufeinander zu weisenden Seitenflächen begrenzt, die an den Schaftwänden des Nadelschafts ausgebildet sind und zwischen denen die Schlitzbreite zu messen ist. Zwischen den Schaftwänden ist der Zungenschlitz angeordnet.The tongue slot, in which the tongue shaft is movably mounted, is arranged in the longitudinal direction of the knitting machine needle and is preferably located in the center of the needle shaft with respect to the needle width, which is measured in the needle transverse direction. It is bounded by two mutually facing side surfaces which are formed on the shaft walls of the needle shaft and between which the slot width is to be measured. Between the shaft walls of the tongue slot is arranged.
Die Breite des Nadelschafts wird senkrecht zu seinen Seitenflächen gemessen. Diese Schaftbreite stimmt im Wesentlichen mit der Weite der Nadelaufnahme in der Strickmaschine überein oder ist geringfügig geringer, damit die Längsverschiebbarkeit der Strickmaschinennadel sicher gestellt ist.The width of the needle shank is measured perpendicular to its side surfaces. This shank width substantially coincides with the width of the needle receptacle in the knitting machine or is slightly smaller, so that the longitudinal displacement of the knitting machine needle is ensured.
Bei einer erfindungsgemäßen Zungennadel ist die Breite des Zungenkopfs vorzugsweise wesentlich kleiner als die Breite des Nadelschafts. Vorzugsweise beträgt die Breite des Zungenkopfs 80 % der Breite des Nadelschafts, wobei die schon die Reduzierung von 5% der Breite Zungenkopfs ausgehend von der Breite des Nadelschafts wesentliche Abstandsvorteile bietet. Idealerweise liegt die Breite des Zungenkopfes zwischen 70 und 90% der Breite des Nadelschafts. Dadurch ist gewährleistet, dass bei der Schwingbewegung der Zunge ausreichend Platz zwischen der Seitenfläche, die den Zungenkopf begrenzt, und dem der Seitenfläche benachbarten Teil einer Strickmaschine vorhanden ist.In a latch needle according to the invention, the width of the tongue head is preferably substantially smaller than the width of the needle shaft. Preferably, the width of the latch head is 80% of the width of the needle shank, with the reduction in travel already afforded by the reduction of 5% of the tab head width from the width of the needle shank. Ideally, the tongue tongue width is between 70 and 90% of the width of the needle shank. This ensures that there is sufficient space between the side surface which delimits the tongue head and the part of a knitting machine adjacent to the side surface during the oscillating movement of the tongue.
Ein weiterer Vorteil eines erfindungsgemäßen Zungenkopfs liegt in seiner Form begründet. Die parallel zueinander stehenden Seitenflächen des Zungenkopfes bieten im Falle einer Berührung mit einem andern Teil einer Strickmaschine eine flächenhafte Anlage. Diese ist im Vergleich zu einer punktförmigen Berührungsstelle weniger anfällig für Verschleiß, ein eventueller Verschleiß ist geringer. Somit ist die Gefahr, dass scharfe Kanten im Bereich des Zungenkopfs entstehen erheblich reduziert.Another advantage of a tongue head according to the invention is due to its shape. The mutually parallel side surfaces of the tongue head provide in the case of contact with another part of a knitting machine a planar system. This is less susceptible to wear compared to a punctiform contact point and any wear is less. Thus, the risk that sharp edges arise in the area of the tongue head is considerably reduced.
Damit die Zasche des Zungenkopfs der erfindungsgemäßen Zungennadel das Ende des Nadelhakens aufnimmt, weist der Nadelhaken eine verjüngte Spitze auf. Diese ist in der Form eines spitz zulaufenden Kegels ausgebildet. Dieser Kegel verjüngt sich ausgehend von dem Hakenquerschnitt zu der Spitze hin. Die Spitze ist gerundet, so dass der Kontakt mit dem Faden an letzterem keine Beschädigungen hinterlässt.In order for the zipper of the tongue head of the latch needle according to the invention to receive the end of the needle hook, the needle hook has a tapered tip. This is formed in the shape of a tapered cone. This cone tapers from the hook cross section to the tip. The tip is rounded so that contact with the thread on the latter leaves no damage.

Die Seitenfläche 21, 22 des Zungenkopfes ist vorzugsweise eine ebene Fläche, die sich weitestgehend über den gesamten Zungenkopf erstrecken kann. Sie geht stufenlos in die Formfläche 26 und in den Zungenschaft 8 über. Die Seitenflächen 21 und 22 sind parallel zueinander angeordnet. Deshalb ist die Breite 16 des Zungenkopfes 9 im wesentlichen konstant. Die Seitenfläche 21 bzw. 22 liegt jeweils in einer Ebene, die zu einer anderen Ebene, in der die Seitenfläche 27 bzw. 28 des Zungenschaftes 8 liegt, parallel ausgerichtet ist.The

Dabei sind der Aufnahmeraum 12 und die Hakenspitze 14 so aneinander angepasst, dass der vordere Bereich der Hakenspitze 14 nahezu vollständig in den Aufnahmeraum 12 eintaucht. Dadurch wird möglich, dass ein Faden ohne Hindernis in den Hakeninnenraum 10, unter die Hakenspitze gleitet. Auch bildet das untere Teil der Hakenspitze 14 keine, gegenüber der Unterkante des Zungenkopfs 9, vorstehende Kante, wenn sich die Zunge in Schließlage befindet (
