PCT No. PCT/EP92/01865 Sec. 371 Date Mar. 23, 1994 Sec. 102(e) Date Mar. 23, 1994 PCT Filed Aug. 14, 1992 PCT Pub. No. WO93/06288 PCT Pub. Date Apr. 1, 1993.A device for clamping and guiding crocheting needles for a crocheting machine. On the one hand a clamping device for the crocheting needles and on the other hand a knock-over comb are to be created, which permit a very fine spacing. To this end, in the bottom part (27) and in the clamping cover (29) of a clamping device (12), opposite, straight needle beds (73, 74) are arranged closely together. The needle beds (73, 74) have wall surfaces that are inclined in a V-shape. A knock-over comb (20, 80) fixed to the machine has upwardly projecting teeth (86) for the crocheting needles. The spacing of the needle beds and guide elements is at least 12, in particular 14 per centimeter of machine width. The holding bar (23) fixed to the machine and the bottom part (27) of the clamping device (12) have recesses, in particular chambers (77, 76) that face one another, which permit the clamping device to move too close to the teeth (86).

Description

BESCHREIBUNG DESCRIPTION
Vorrichtung zum Einspannen und Führen von Häkelnadeln für eine Häkelmaschine. Device for clamping and guiding crochet hooks for a crochet machine.
Die Erfindung bezieht sich auf eine Vorrichtung zum Einspannen und Führen von Häkelnadeln, insbesondere Zungennadeln, Spitzennadeln und die unter Fachleuten "Patentnadeln" genannten Häkelnadeln. Die Vorrichtung soll anwendbar sein, allgemein bei Häkelmaschinen, insbesondere bei Häkelgalonmaschinen (crotchet galloon machines). Aus der EP-PS 0 110 271 (BERGER) ist eine Vorrichtung zum Einspannen von Häkelnadeln bekannt, die dort aber nicht mit einem an sich bekannten Abschlagkamm, sondern mit einer Abschlagschiene mit einer oberen freien, geraden Kante zusammenarbeitet. Andererseits ist eine spezielle Ausführungsform von Unterteil und Klemmdeckel einer Einspannvorrichtung für Häkelnadeln aus der EP-PS 0 244656 (BERGER) bekannt. Dort werden die Nadelschäfte in rechteckige Nuten von Unterteil und Klemmdeckel eingesetzt, zwischen denen rechteckige Stege verbleiben. The invention relates to a device for clamping and guiding crochet hooks, in particular latch needles, point needles and the crochet hooks called "patent needles" by experts. The device is said to be applicable, generally in crochet machines, especially in crochet galloon machines. From EP-PS 0 110 271 (BERGER) a device for clamping crochet hooks is known, which does not work there with a knock-off comb known per se, but with a knock-off rail with an upper free, straight edge. On the other hand, a special embodiment of the lower part and clamping cover of a clamping device for crochet hooks is known from EP-PS 0 244656 (BERGER). There the needle shafts are inserted into rectangular grooves in the lower part and clamping cover, between which rectangular bars remain.
Durch die vorliegende Erfindung sollen einerseits eine Einspannvorrichtung für die Häkelnadeln, andererseits ein Abschlagkamm geschaffen werden, die eine sehr feine Teilung, nämlich mindestens 12, insbesondere 14, jedoch auch mehr Nadeln je cm Plaschinenbreite ermöglichen. Es erwies sich als unzweckmäßig, im Querschnitt rechteckige Nuten in dieser hohen Feinheit einzufrasen. Ein Problem war dabei die Erzielung der notwendigen Präzision. Andererseits erwies es sich als unzweckmäßig, mit einer Abschlagschiene mit gerader Oberkante zu arbeiten. Es war vielmehr nötig, die Nadelschäfte zu führen, um zu verhindern, daß von den zugehörigen Lochnadeln die Kettfäden um verkehrte oder je zwei Häkelnadelköpfe geführt werden. Darüber hinaus waren Maßnahmen nötig, um zu erreichen, daß auch bei der hohen erwünschten Feinheit die gegenseitigen Abstände der Längsfäden eines zu häkelnden Bandes od. dgl. bei der Maschenbildung genau eingehalten werden. The present invention is intended on the one hand to create a clamping device for the crochet needles and on the other hand to provide a knock-off comb which enables a very fine division, namely at least 12, in particular 14, but also more needles per cm machine width. It turned out to be unsuitable to mill grooves with such a high degree of fineness in cross-section. One problem was achieving the necessary precision. On the other hand, it turned out to be inappropriate to work with a straight top edge tee. Rather, it was necessary to guide the needle shafts in order to prevent the warp threads from being guided around the wrong or two crochet needle heads by the associated perforated needles. In addition, measures were needed to achieve that the mutual spacing of the longitudinal threads of a ribbon to be crocheted or the like is precisely observed in the stitch formation, even with the high desired fineness.
Durch die Erfindung nach Anspruch 1 läßt sich durch eine geschickte Kombination verschiedener Maßnahmen, von denen nur wenige je für sich bekannt sind, diese Aufgabe lösen. Es lassen sich überraschenderweise damit Bänder, insbesondere elastische Bänder häkeln, deren Längsfäden auch bei einer Teilung von insbesondere 14 je cm Maschinenbreite gleiche gegenseitige Abstände haben, so daß ein sehr gleichmäßig aussehendes Band erzeugt werden kann. The invention according to claim 1 can be achieved by a clever combination of various measures, only a few of which are known per se. Surprisingly, it can be used to crochet ribbons, in particular elastic ribbons, the longitudinal threads of which have the same mutual spacing even with a division of in particular 14 per cm of machine width, so that a very uniform-looking ribbon can be produced.
Ferner werden die Probleme der Einspannung und Führung der Häkelnadeln auf einwandfreie Weise gelöst. Als wesentlich für die hohe Präzision bei der Herstellung der Nuten der Klemmvorrichtung und der präzisen Einapannung der Nadelschäfte erwies sich die V-artige Anordnung der Uandflächen der Nuten (Nadelbetten). Furthermore, the problems of clamping and guiding the crochet hooks are solved in a flawless manner. The V-like arrangement of the edges of the grooves (needle beds) proved to be essential for the high precision in the production of the grooves of the clamping device and the precise clamping of the needle shafts.
Ein weiterer wesentlicher Gesichtspunkt liegt darin, eine Möglichkeit zu schaffen, die Klemmvorrichtung bis sehr dicht an die Zinken des Nadelkammes heranzuführen, so daß sich die Lagerung der Häkelnadeln innerhalb der Klemmvorrichtung auch auf den Teil der Häkelnadeln auswirkt, der im Betrieb über die Zinken ins Freie vorsteht. Another important aspect is to create a way to bring the clamping device very close to the tines of the needle comb, so that the storage of the crochet hooks within the clamping device also affects the part of the crochet hooks that is in operation via the tines to the outside protrudes.
Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen. Further developments of the invention result from the subclaims.
Die Genauigkeit der gegenseitigen Abstände der in gehäkelten Bändern längs verlaufenden Fäden läßt sich gemäß Anspruch 2 durch geschickte Uahl der Einspannlänge der Häkelnadeln positiv beeinflussen. Sind die Köpfe der Häkelnadeln beim Abschlagvorgang so weit zurückziehbar, daß sie z. B. nur noch um 2 mm vorstehen, so ist keine Ungleichmäßigkeit des gehäkelten Bandes mehr wahrnehmbar. Nach Anspruch 3 lassen sich die mit Zinken versehenen Teile des Abschlagkammes in einer nach oben offenen Nut einer Halteschiene unterbringen, wodurch eine hohe Präzision der gegenseitigen Abstände der Zinken erzielbar ist. The accuracy of the mutual spacing of the threads running longitudinally in crocheted bands can be positively influenced according to claim 2 by skillful selection of the clamping length of the crochet hooks. Are the heads of the crochet hooks so far retractable during the tee that they z. B. only protrude by 2 mm, so no unevenness of the crocheted band is perceptible. According to claim 3, the pronged parts of the tapping comb can be accommodated in an upwardly open groove of a holding rail, whereby a high precision of the mutual spacing of the prongs can be achieved.
Der Abschlagkamm läßt sich in prinzipiell zwei verschiedenen Ueisen ausgestalten, nämlich einerseits gemäß Anspruch 5 durch dicht nebeneinander angeordnete Klötzchen, deren jeder eine nach oben stehende Zinke aufweist, andererseits gemäß Anspruch 6 durch Platten, die oben Zinken mit V-artig schräg gegeneinander geneigten Uandflachen haben. The knock-off comb can in principle be designed in two different ways, namely on the one hand according to claim 5 by closely arranged blocks, each of which has an upstanding tine, on the other hand according to claim 6 by plates which have tines with V-like inclined surfaces on the top .
Die so erzeugten Nuten haben insbesondere eine dreieckige Form, können aber rechteckige oder irgendwelche Zwischenformen haben. Uichtig ist, daß die Nadelschäfte von oben eingeführt werden können und seitlichen Halt haben. The grooves produced in this way have, in particular, a triangular shape, but can have rectangular or any intermediate shapes. It is important that the needle shafts can be inserted from above and have lateral support.
Schließlich können die Schäfte der Häkelnadeln andere als die gebräuchlichen Querschnittsformen haben. Sie können insbesondere gemäß Anspruch 9 oben und unten je eine spitze Kante oder gemäß Anspruch 10 eine abgerundete Kante haben. Finally, the shafts of the crochet hooks can have cross-sectional shapes other than those used. In particular, they can each have a pointed edge at the top and bottom or a rounded edge according to claim 10.

Fig. 1 und 2 zeigen eine Anordnung von Häkelwerkzeugen ähnlich der nach Fig. 1 der europäischen Patentschrift 110 271 (BERGER). Man erkennt in Fig. 1 und 2 eine von mehreren in eine Klemmvorrichtung 12 eingespannten Häkelnadeln 10 mit einem Schaft 10a und einem Kopf 10b, sowie eine Lochnadel 2 aus einer Gruppe nebeneinander an einer Lochnadelschiene 3 angeordneter Lochnadeln, die zur Zuführung von Kettfäden 4 dienen. Ein Fadenkamm 6 dient zur Zuführung einer Gruppe elastischer Fäden 8. Schußfadenführer 14 und 15, die quer zur Zeichenebene bewegt werden, dienen zur Zuführung von Schußfäden 17 und 18. Das durch Maschenbildung gefertigte elastische Band 22 wird in Richtung des Pfeils 26 nach unten abgezogen. Diese Anordnung läßt sich unter anderem zur Herstellung elastischer Bänder mit Häkelspitze verwenden. 1 and 2 show an arrangement of crochet tools similar to that of FIG. 1 of European Patent 110 271 (BERGER). 1 and 2, one of a plurality of crochet hooks 10 clamped in a clamping device 12 with a shaft 10a and a head 10b, as well as a piercing needle 2 from a group of piercing needles arranged next to one another on a piercing needle rail 3, which are used to feed warp threads 4. A thread comb 6 is used to feed a group of elastic threads 8. Weft guides 14 and 15, which are moved transversely to the plane of the drawing, serve to feed weft threads 17 and 18. The elastic band 22 made by stitching is pulled down in the direction of arrow 26. This arrangement can be used, among other things, for the production of elastic ribbons with a crochet tip.
Eine in Fig. 1 und 2 links dargestellte Klemmvorrichtung 12 für die Schäfte 10a der Häkelnadeln ist in bekannter Weise an einer Nadelbarre 25 befestigt und mit dieser nach links und rechts bewegbar. Fig. 2 zeigt die linke Endstellung, Fig. 1 die rechte. Die Klemmvorrichtung 12 hat einen Klemmdeckel 29 und einen Unterteil 27, die beide mit Hilfe von Schraubbolzen 19 zum Einspannen der Häkelnadeln aneinanderzudrücken sind. A clamping device 12 for the shafts 10a of the crochet hooks shown on the left in FIGS. 1 and 2 is fastened in a known manner to a needle bar 25 and can be moved to the left and right with it. Fig. 2 shows the left end position, Fig. 1 the right. The clamping device 12 has a clamping cover 29 and a lower part 27, both of which are to be pressed together with the aid of screw bolts 19 for clamping the crochet hooks.
Fig. 3 ist ein Teilquerschnitt der Klemmvorrichtung in einer Ebene VI-VI in Fig. 2. In Klemmdeckel 29 und Unterteil 27 sind, einander exakt gegenüberliegend, dicht nebeneinander V-förmige Nuten 73 bzw. 74 mit schrägen Uandflächen 78 gefräst. Die Nuten verlaufen über die ganze in Figur 2 erkennbare Breite von Klemmdeckel und Unterteil und haben alle die gleiche Form und Breite. In Fig. 3 ist nur ein Teil der Nuten dargestellt. Die Gruppe der Nuten hat man sich nach rechts ergänzt zu denken. Fig. 3 is a partial cross section of the clamping device in a plane VI-VI in Fig. 2. In the clamping cover 29 and lower part 27, exactly opposite each other, V-shaped grooves 73 and 74 are milled with inclined wall surfaces 78, closely next to each other. The grooves run over the entire width of the clamping cover and lower part which can be seen in FIG. 2 and all have the same shape and width. In Fig. 3 only part of the grooves is shown. The group of grooves is thought to have been added to the right.
In Figur 3 rechts ist eine Gruppe von Schäften 10a1 von Häkelnadeln dargestellt, die oben und unten je eine spitze Kante 89 (Figur 8) haben, (bevorzugte Form). Links in Figur 3 sind einzelne Schäfte 10a2 und 10a3 dargestellt, die andere Querschnittsformen haben, nämlich eine rechteckige Form (10a3) oder eine Form mit abgerundeter Ober- und Unterseite (10a2). Es werden jeweils nur Nadeln einer einzigen Querschnittsform eingesetzt. FIG. 3 on the right shows a group of shafts 10a1 of crochet hooks, each of which has a pointed edge 89 (FIG. 8) at the top and bottom (preferred form). Individual shafts 10a2 and 10a3 are shown on the left in FIG. 3, which have other cross-sectional shapes, namely a rectangular shape (10a3) or a shape with rounded top and bottom (10a2). Only needles of a single cross-sectional shape are used in each case.
Bei einer 14er-Teilung beträgt jede Einheit E in Fig. 3 aus Nadel und zugehörigem Zwischenraum 0,71 mm. Damit die Kettfäden 4 und die elastischen Fäden 8 sowie ihre Knoten zwischen benachbarten Häkelnadeln hindurchgeführt werden können, sind Zwischenräume von 0,33 mm erforderlich. Damit verbleibt für die Häkelnadeln eine Breite von 0,38 mm. With a division of 14, each unit E in FIG. 3 of needle and associated space is 0.71 mm. So that the warp threads 4 and the elastic threads 8 and their knots can be passed between adjacent crochet hooks, gaps of 0.33 mm are required. This leaves a width of 0.38 mm for the crochet hooks.
Für eine 15er-Teilung und noch feinere Teilungen gilt Entsprechendes. Zur Erzielung gröberer Teilungen, als in Figur 3 rechts dargestellt, können die Nadeln nur in jedes zweite, dritte, vierte usw. Nutpaar gesetzt werden. The same applies to a division of 15 and even finer divisions. To achieve coarser divisions than shown on the right in FIG. 3, the needles can only be inserted into every second, third, fourth, etc. pair of grooves.
Die Anordnung mit dreieckigen Nuten ermöglicht es einerseits, Nuten sehr dicht nebeneinander einzufrasen, was für die erwünschte hohe Teilung erforderlich ist, andererseits einzelne Nadeln nach Lösen der Verschraubung der Klemmvorrichtung herauszuziehen und durch neue zu ersetzen, wobei die übrigen Nadeln in ihrer bisherigen Position unverändert liegen bleiben. The arrangement with triangular grooves makes it possible, on the one hand, to mill grooves very close to one another, which is necessary for the desired high pitch, on the other hand, to pull out individual needles after loosening the screw connection of the clamping device and to replace them with new ones, the other needles remaining unchanged in their previous position stay.
Uie Fig. 1 und 2 zeigen, werden Klemmdeckel 29 und Unterteil 27 durch Schraubbolzen 19 gegeneinander gepreßt. Durch nicht dargestellte, aber bekannte Mittel wird dafür gesorgt, daß sich der Klemmdeckel 29 nicht gegenüber dem Unterteil 27 in waagerechter Richtung (rechts-links in Figur 3) verschieben kann, so daß eine Schiefstellung der Nadelschäfte sicher vermieden wird. 1 and 2 show, clamping cover 29 and lower part 27 are pressed against one another by screw bolts 19. By means, not shown, but known means, it is ensured that the clamping cover 29 cannot move in a horizontal direction (right-left in FIG. 3) relative to the lower part 27, so that an oblique position of the needle shafts is reliably avoided.
Figur 1 und 2 zeigen eine maschinenfest angeordnete Haupttraverse 21, an der ein Abschlagkamm 20 befestigt ist. Zum Abschlagkamm gehört eine plattenartige Halteschiene 23, die sich in Richtung der Maschinenbreite erstreckt und lotrecht steht. Uie in Fig. 1 und 2 dargestellt ist, ist von oben her in die Halteschiene eine Nut 23a gefräst. Fig. 4 zeigt einen Ausschnitt des Abschlagkamms 20. In die Nut sind dicht nebeneinander Klötzchen 70 gesetzt, die je mittig eine nach oben stehende Zinke 70a haben. Freie, im Querschnitt rechteckige Rinnen 71 zwischen je zwei Zinken dienen zur Führuung von Schaft 10a und Kopf 10b je einer Häkelnadel 10. Die Klötzchen 70 werden in die Nut zunächst nur dicht nebeneinander eingesetzt und erst anschließend mit Klebstoff befestigt. Dies soll gewährleisten, daß die Klötzchen dicht aneinander liegen, und daß sich sehr genaue Abstände zwischen den Zinken 70a ergeben. Diese Konstruktion ist geeignet für sehr feine Teilungen (bis zu einer 16er-Teilung), wo es auf hohe Präzision der gegenseitigen Abstände der Rinnen 71 zur Führung der Nadeln ankommt. In Fig. 1 und 2 rechts vom Abschlagkamm 20 ist eine Rückhaiteschiene 24 angeordnet, und zwar so, daß zwischen beiden Platz zum Abziehen der fertig gehäkelten elastischen Bänder 22 bleibt. FIGS. 1 and 2 show a main traverse 21 which is arranged in a machine-fixed manner and to which a tapping comb 20 is attached. A plate-like holding rail 23, which extends in the direction of the machine width and is perpendicular, belongs to the tapping comb. As shown in FIGS. 1 and 2, a groove 23a is milled from above into the holding rail. FIG. 4 shows a section of the knock-off comb 20. In the groove, blocks 70 are placed closely next to one another, each of which has a prong 70a standing up in the center. Free channels 71 with a rectangular cross-section between two prongs each serve to guide the shaft 10a and head 10b of a crochet hook 10. The blocks 70 are initially inserted into the groove only close to one another and only then fastened with adhesive. This is to ensure that the blocks are close together and that there are very precise distances between the tines 70a. This construction is suitable for very fine divisions (up to a division of 16), where high precision of the mutual spacing of the channels 71 for guiding the needles is important. In Fig. 1 and 2 to the right of the tee comb 20, a back rail 24 is arranged, so that there is space between the two for pulling the finished crocheted elastic bands 22.
Bei Verwendung sehr dünner Häkelnadeln 10 ist es wichtig, daß die Klemmvorrichtung 12 möglichst dicht an die Zinken 70a des Abschlagkammes 20 geführt werden kann, damit der aus der Klemmvorrichtung vorstehende Teil der Häkelnadeln möglichst kurz wird. Um dies zu ermöglichen, haben die Halteschiene 23 einerseits und der Unterteil 27 der Klemmvorrichtung andererseits zueinander passende Ausnehmungen, z.B. Abschrägungen 77 bzw. 76. Uie Fig. 1 zeigt, läßt sich so die Klemmvorrichtung bis dicht an die Zinken 70a heranführen. When using very thin crochet hooks 10, it is important that the clamping device 12 can be guided as close as possible to the prongs 70a of the knock-over comb 20 so that the part of the crochet hooks protruding from the clamping device is as short as possible. To make this possible, the holding rail 23 on the one hand and the lower part 27 of the clamping device on the other hand have matching recesses, e.g. Bevels 77 and 76. As shown in FIG. 1, the clamping device can thus be brought close to the prongs 70a.
Dazu passend, ist die Einspannlänge der Häkelnadel-Schäfte so gewählt, daß die Köpfe 10b der Häkelnadeln so weit nach links zurückgezogen werden können, daß sie nur noch um etwa 2 mm aus den Führungsräumen zwischen den Zinken 70a vorstehen (Figur 2). In dieser Position werden die gebildeten Maschen abgeschlagen. Dadurch, daß die freistehenden Nadelteile sehr präzise geführt sind, wird die Verwendung sehr dünner Häkelnadeln von 0,38 mm Breite und weniger ermöglicht. Andererseits werden die gegenseitigen Abstände der Nadelköpfe beim Abschlagen sehr genau eingehalten. So ergibt sich ein gutaussehendes Band, bei dem die Abstände zwischen den elastischen Fäden 8 keine sichtbaren Unterschiede haben. To match this, the clamping length of the crochet hook shafts is selected so that the heads 10b of the crochet hooks can be retracted to the left so far that they only protrude from the guide spaces between the tines 70a by about 2 mm (FIG. 2). The stitches formed are knocked off in this position. Because the free-standing needle parts are guided very precisely, the use of very thin crochet needles of 0.38 mm width and less is made possible. On the other hand, the mutual distances between the needle heads are kept very precisely when knocking off. The result is a good-looking band in which the distances between the elastic threads 8 have no visible differences.
Fig. 5 und 6 zeigen eine abweichende Ausbildung eines Abschlagkammes 80. Gleiche Teile wie in Fig. 1 und 2 sind hier mit denselben Bezugszeichen versehen, so die Halteschiene 23 mit einer z. B. durch Fräsen hergestellten Nut 23a. In diese Nut werden nebeneinander dünne Platten B2 eingesetzt und durch Kleben befestigt. Oede Platte hat oben dreieckige Zinken 86 (mit schrägen Uandflächen 85) von der gleichen Größe und Form wie die Zinken, die sich nach Figur 3 zwischen den Nadelbetten 73 und 74 ergeben. Jede Platte 82 hat eine größere waagerechte Länge als in Fig. 5 dargestellt, so daß eine Gruppe gemeinsam zum Häkeln eines Bandes zusammenwirkender Nadeln von einer einzigen Platts geführt werden kann. Passend zu dieser Dreieckform der Zinken und Rinnen können Nadeln verwendet werden, deren Schäfte 10a1 oben und unten je eine spitze Kante 89 haben, wie es Fig. 8 zeigt. 5 and 6 show a different design of a tapping comb 80. The same parts as in FIGS. 1 and 2 are provided with the same reference numerals here, so the holding rail 23 with a z. B. groove 23a produced by milling. Thin panels B2 are inserted next to each other in this groove and fastened by gluing. The top of each plate has triangular tines 86 (with sloping wall surfaces 85) of the same size and shape as the tines that result between the needle beds 73 and 74 according to FIG. 3. Each plate 82 has a greater horizontal length than that shown in Fig. 5 so that a group of co-operating needles can be guided together from a single plate to crochet a band of needles. Matching this triangular shape of the tines and grooves, needles can be used, the shafts 10a1 of which have a pointed edge 89 at the top and bottom, as shown in FIG. 8.
Die Platten 82, ebenso wie die Klötzchen 70 mit Zinken 70a nach Figur 4 bestehen z. B. aus Messing. Auch Kupfer, Bronze oder ein passender Kunststoff können verwendet werden, so daß sich möglichst wenig Reibung zwischen den Rinnen 84 bzw. 71 und den aus Stahl bestehenden Häkelnadeln 10 ergibt. The plates 82, as well as the blocks 70 with prongs 70a according to FIG. B. made of brass. Copper, bronze or a suitable plastic can also be used, so that there is as little friction as possible between the grooves 84 and 71 and the crochet hooks 10 made of steel.
Die gegenseitige Höhenlage der Häkelnadeln 10 und der Rinnen 71 bzw. 84 nach Figur 4, 5 und 6 wird so justiert, daß im Betrieb die Unterkanten der Nadeln sich frei innerhalh der Rinnen hin und her bewegen. Die Zinken 70a (Figur 4) haben gegenseitige Abstände, die größer sind als die Dicke der Häkelnadeln. Als Folge beider Maßnahmen berühren die Häkelnadeln die Uände der Rinnen 71, 84 nur gelegentlich, wenn eine Korrektur erforderlich ist. Auf diese Ueise wird die Reibung auf ein Mindestmaß herabgesetzt. The mutual height of the crochet hooks 10 and the grooves 71 and 84 according to FIGS. 4, 5 and 6 is adjusted so that the lower edges of the needles move freely within the grooves during operation. The tines 70a (Figure 4) are spaced apart from one another which are greater than the thickness of the crochet hooks. As a result of both measures, the crochet hooks only occasionally touch the walls of the channels 71, 84 when a correction is required. In this way, the friction is reduced to a minimum.
Die Nadelbetten 73 und 74 (Fig. 3) und die Rinnen 84 (Fig. 5) müssen nicht unbedingt Dreieckform haben, sie müssen also nicht einen spitzen Boden 83 haben, und die Zinken 86 nach Fig. 5 und entsprechend nach Fig. 3 müssen ebenfalls nicht in spitzen Kanten 81 auslaufen. Uie Fig. 7 zeigt, können die Böden der Rinnen 84a als Rundflächen 83a ausgebildet sein und die Zinken 86a in Rundflächen 81a auslaufen. Dies gilt entsprechend auch für Unterteil 27 und Klemmdeckel 29 nach Fig. 1 und 2. The needle beds 73 and 74 (FIG. 3) and the grooves 84 (FIG. 5) do not necessarily have to have a triangular shape, that is to say they do not have to have a pointed bottom 83, and the tines 86 according to FIG. 5 and accordingly according to FIG. 3 must likewise do not run out in pointed edges 81. 7 shows, the bottoms of the grooves 84a can be designed as round surfaces 83a and the tines 86a end in round surfaces 81a. This also applies accordingly to lower part 27 and clamping cover 29 according to FIGS. 1 and 2.
Bei Verwendung von Platten 82a mit Rinnen 84a nach Fig. 7 können die Nadelschäfte 10a3 entsprechend abgerundete Kanten 90 haben (Figur 9). When using plates 82a with grooves 84a according to FIG. 7, the needle shafts 10a3 can have correspondingly rounded edges 90 (FIG. 9).
