Description

Die Erfindung richtet sich auf eine Nadel für einen Nadelstreifen bzw. -stab, wobei die Nadel im Fußbereich einen Befestigungsabschnitt und oberhalb desselben einen kämmwirksamen Spitzenabschnitt aufweist, sowie auf einen Nadelstreifen, der mit derartigen Nadeln ausgestattet ist, wobei die Nadel als Stanzteil ausgebildet ist und der Befestigungsbereich eine nach außen hin offene oder geschlossene Ausnehmung zum Aufschieben der Nadel auf einen Tragestab aufweist, wobei die Ausnehmung derart korrespondierend zum Querschnitt des Tragestabs unrund bzw. mit Vorsprüngen oder Einschnitten versehen ausgebildet ist, daß die Nadel auf dem Tragestab drehfest angeordnet ist. Solche Nadeln sind aus der DE 19 36 323 A1 bekannt.The invention is directed to a needle for a pinstripe or -stab, the needle in the foot area and a fastening section above it has a combable tip section, and on a pinstripe equipped with such needles, wherein the needle is designed as a stamped part and the fastening area recess open or closed to the outside for sliding the Has a needle on a support rod, the recess corresponding in this way to the cross section of the support rod out of round or with projections or incisions is formed that the needle on the support rod is rotatably arranged. Such needles are from DE 19 36 323 A1 known.

Die Nadeln der Nadelstreifen an derartigen Textilmaschinen unterliegen im Betrieb einem Verschleiß bzw. sie brechen ab. Deshalb ist es erforderlich, die Nadelstreifen nach einer bestimmten Betriebsdauer auszutauschen. Dementsprechend müssen derartige Nadelstreifen einerseits leicht einsetzbar und leicht lösbar mit dem Nadelträger zu verbinden sein, andererseits muß im Betrieb ein absolut sicherer Sitz der Nadelstreifen im Nadelträger gewährleistet sein. The needles of the pinstripes on such textile machines are subject to Operation wear or they break off. Therefore it is necessary replace the pinstripes after a certain period of operation. Accordingly, such pinstripes must be easy to use and easy to connect to the needle carrier, on the other hand During operation, the pin strips must sit absolutely securely in the needle holder to be guaranteed.

Hierzu sind verschiedene Befestigungstechniken entwickelt worden. Insbesondere ist es bekannt, Nadelstreifen, als eine vorkonfektionierte Nadelreihe, im Nadelträger bzw. in einer Längsnut desselben durch Löten festzulegen. Weiterhin ist eine Befestigung durch Kleben bekannt geworden. Andere Lösungen sehen vor, daß an den Seitenwänden des Fußes der Nadelstreifen noppenartige Vorsprünge angebracht sind, so daß die Nadelstreifen bajonettverschlußartig in korrespondierende Nuten des Nadelstreifenträgers eingesetzt werden können.Various fastening techniques have been developed for this. Especially it is known to be pin strips, as a pre-assembled row of needles, in the needle carrier or in a longitudinal groove of the same by soldering. Fastening by gluing has also become known. Other solutions provide that the pinstripes on the side walls of the foot knob-like projections are attached so that the pinstripes Bayonet-like in corresponding grooves of the pinstripe wearer can be used.

Diese vorbekannten Lösungen sind deshalb nachteilig, weil sie entweder in der Handhabung nicht hinreichend einfach sind, keine ausreichend sichere Befestigung gewährleisten oder aber sich nicht für Nadelstreifen mit einem durch einen Kunststoffstreifen gebildeten Fuß eignen.These previously known solutions are disadvantageous because they are either are not sufficiently simple to use, none are sufficient Ensure secure attachment or not for pinstripes with a foot formed by a plastic strip.

Aus der deutschen Patentanmeldung 40 33 262 A1 der Anmelderin (entsprechend dem US-Patent 5 201 098) ist eine Lösung zur Festlegung von Nadeln an einem Nadelstab bekannt, die gegenüber vorbekannten Lösungen eine erleichterte Austauschbarkeit ermöglicht, wobei die einzelnen, in konventioneller Weise hergestellten und ausgebildeten Nadeln längs ihres Fußbereiches durch einen Kunststoffstreifen zusammengefaßt sind, und wobei dieser Streifen dann seinerseits wieder in einem Tragestab befestigt wird. Allerdings ist es, wie dargelegt, auch bei einer derartigen an sich gegenüber dem damals bekannten Stand der Technik vorteilhaften Befestigungsart erforderlich, die einzelnen Nadeln zunächst zusammenzufassen.From German patent application 40 33 262 A1 by the applicant (accordingly U.S. Patent 5,201,098) is a solution for specifying Needles on a needle stick are known, compared to previously known solutions facilitates interchangeability, the individual, in conventionally manufactured and trained needles along their Foot area are summarized by a plastic strip, and wherein this strip then in turn fastened in a carrying rod becomes. However, as stated, it is also such in itself compared to the known prior art advantageous type of attachment necessary to first summarize the individual needles.

Für manche Anwendungszwecke ist es weiterhin bekannt geworden, statt einer Garnitur aus einzelnen Nadeln, die dann in der vorher beschriebenen Weise arrangiert werden müssen, eine Garnitur aus sogenannten Sägezahnstanzteilen vorzusehen, welche dann entweder in Form von umlaufenden Sägezahn-Drähten oder von einzelnen Stanzteil-Abschnitten aufgebracht werden. Für die Befestigung von Stanzteilen ist es bekannt Schwalbenschwanzkonfigurationen vorzusehen, um diese Stanzteile beispielsweise auf einem Rundkamm formschlüssig aufreihen und befestigen zu können. Ein Beispiel hierfür ist das europäische Patent 0 179 158 der Anmelderin. For some applications it has become known instead a set of individual needles, which are then described in the previous A set of so-called sawtooth stampings must be arranged in a way to be provided, which then either in the form of revolving Sawtooth wires or applied from individual stamped sections will. Dovetail configurations are known for fastening stamped parts to provide, for example, on these stamped parts to be able to line up and fasten a circular comb. A An example of this is the applicant's European patent 0 179 158.

Es hat sich allerdings gezeigt, daß bei bestimmten Anwendungen, beispielsweise in Streckwerken, das Vorsehen von Nadelstäben Vorteile aufweist gegenüber der Verwendung von Stanzteilen.However, it has been shown that in certain applications, for example in drafting systems, the provision of needle bars has advantages compared to the use of stamped parts.

Aus der gattungsgemäßen DE 19 36 323 A1 ist es bekannt, zum Ordnen von Fadenscharen durch Nadelkämme Blechscheiben drehgesichert nebeneinander aufzureihen, wobei jede runde Blechscheibe einen als Nadel bezeichneten Ansatz aufweist, der sich in radialer Richtung über eine vergleichsweise kleine Strecke bezogen auf den Durchmesser des Grundkörpers der Scheibe erstreckt. Bei dieser bekannten Ausführungsform wurde es als wesentlich angesehen, eine Walze mit einem Nadelkamm unter Verwendung möglichst dünner Bleche zu schaffen, so daß der Spitzenabstand sehr klein gehalten werden konnte, wobei man im Hinblick auf den Einsatzbereich solcher Kämmwalzen davon ausging, daß es gleichgültig sei, welche Form die Na- del habe. Derartige Walzen eignen sich nicht für Kämmaufgaben, wie sie beispielsweise in Streckwerken vorkommen, wo ein relativ langer kämmwirksamer Spitzenbereich bei einer typischen langgestreckten Konfiguration der Nadel erforderlich ist, und wobei die Nadel auch nadelspezifisch im Querschnitt mit abgerundeten Kanten ausgebildet ist.From the generic DE 19 36 323 A1, it is known to line up sheets of sheets by needle combs to arrange sheet-metal disks in a rotationally secure manner next to one another, each round sheet-metal disk having an attachment called a needle, which extends in the radial direction over a comparatively small distance in relation to the diameter of the base body the disc extends. In this known embodiment it was considered essential to create a roller with a needle comb using the thinnest possible sheets, so that the tip spacing could be kept very small, it being assumed with regard to the area of use of such combing rollers that it was indifferent, what form the Na -'ve del. Such rollers are not suitable for combing tasks, as they occur, for example, in drafting systems, where a relatively long combing tip area is required with a typical elongated configuration of the needle, and the needle is also designed with a cross-section with rounded edges, specific to the needle.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, Nadeln und hiermit garnierte Nadelstreifen bzw. -stäbe so auszugestalten, daß die vorteilhaften Kämmwirkungen von Nadeln erreicht werden und trotzdem ein leichter Austausch der Nadeln bewerkstelligt werden kann, so daß nur minimale Maschinenstandzeiten zur Bewerkstelligung des Austausches in Kauf genommen werden müssen.Proceeding from this, the invention is based on the object of needles and hereby garnished pinstripes or rods so that the advantageous combing effects of needles can be achieved and still a easy replacement of the needles can be accomplished, so that only minimum machine downtimes to complete the exchange in Purchase must be made.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß für Textil-KämmMaschinen, insbesondere Streckwerke, Intersecting-Maschinen, Speisekämme, Fixkämme, Rundkämme od.dgl. der Spitzenbereich der Nadeln deutlich höher ist als der Befestigungsbereich und durch Prägen im Querschnitt etwa oval geformt ist.This object is achieved in that for textile combing machines, in particular drafting systems, intersecting machines, food combs, Fixed combs, round combs or the like. the tip area of the needles is significantly higher than the mounting area and by embossing in the Cross-section is approximately oval shaped.

Dieser Ausgestaltung liegt die Erkenntnis zugrunde, daß mit modernen Herstellungstechniken auch einzelne Nadeln durch Stanzen so hergestellt werden können, daß der Spitzenbereich die vorteilhafte Kämmwirkung einzelner Nadeln aufweist. Gleichzeitig eröffnet diese Herstellungstechnik aber die Möglichkeit, den Befestigungsbereich in der erfindungsgemäßen Weise zu gestalten, so daß es im Gegensatz zu allen vorbekannten Nadelstreifen nicht mehr erforderlich ist, die Nadeln zu einem Streifen zusammenzufassen und dementsprechend vorzukonfektionieren, sondern die herkömmliche Differenzierung zwischen Nadelstreifen und Tragestab wird aufgehoben, indem die einzelnen Nadeln unmittelbar und individuell auf den Tragestab aufgesetzt werden können, der dann seinerseits direkt in der Maschine mechanisch, z.B. durch eine Verschraubung, montiert werden kann.This configuration is based on the knowledge that with modern Manufacturing techniques also made single needles by punching can be that the tip area the beneficial combing effect of individual Has needles. At the same time, this manufacturing technique opens up but the possibility of the attachment area in the invention To design way so that it is in contrast to all known pinstripes it is no longer necessary to combine the needles into a strip and pre-assemble accordingly, but the conventional differentiation between pinstripes and carrying stick canceled by the individual needles immediately and individually the carrying rod can be put on, which then in turn directly in the machine mechanically, e.g. by means of a screw connection can.

Die Ausnehmung kann beispielsweise annähernd oval oder rechteckig ausgebildet sein und einen nach außen hin offenen Bereich aufweisen, wobei durch diesen offenen Bereich die Möglichkeit eröffnet wird, die Ausnehmung leicht elastisch aufzuweiten und hierdurch eine gewisse Vorfixierung beim Aufreihen zu ermöglichen.The recess can, for example, be approximately oval or rectangular be and have an area open to the outside, wherein this open area opens up the possibility of the recess slightly elastic to expand and thereby a certain amount of pre-fixation to enable when lining up.

Alternativ oder zusätzlich kann vorgesehen sein, daß der Befestigungsbereich noch eine zweite Ausnehmung zum Aufreihen der Nadeln vor dem aufbringen auf den Tragestab aufweist. Dementsprechend kann die Garnitur bestehend aus einer Reihe von Nadeln für einen Tragestab schon vorbereitet werden, wobei dann der gleiche Nadelstab in kürzester Zeit von der alten Garnitur befreit und mit der neuen Garnitur versehen werden kann.Alternatively or additionally, it can be provided that the fastening area a second recess to line up the needles in front of the apply to the support rod. Accordingly, the set can consisting of a row of needles already prepared for a carrying rod the same needle bar in the shortest possible time from of the old set and be freed with the new set can.

Die Erfindung richtet sich auch auf einen Nadelstreifen, den man in der herkömmlichen Terminologie auch als Nadelstab bezeichnen könnte, und der sich dadurch auszeichnet, daß ein Tragestab vorgesehen ist, dessen Querschnittskonfiguration der Kontur der Ausnehmung der darauf aufgereihten Nadeln entspricht.The invention is also directed to a pinstripe that is used in the conventional terminology could also be called a needle bar, and which is characterized in that a carrying rod is provided, the Cross-sectional configuration of the contour of the recess of the lined up Corresponds to needles.

Dabei kann der Tragestab wenigstens eine Längsnut bzw. einen Längsschlitz zum Eingriff eines korrespondierenden Vorsprungs der Nadeln aufweisen. Dies läßt sich besonders leicht dadurch realisieren, daß der Tragestab als geschlitztes Rohr ausgebildet ist. The support rod can have at least one longitudinal groove or slot to engage a corresponding projection of the needles. This can be realized particularly easily in that the carrying rod is designed as a slotted tube.

Zur Ausbildung eines Nadelstreifens bzw. -stabes mit optimal distanzierten Nadeln in axialer Richtung können Abstandshalteteile vorgesehen sein, deren Form in etwa der Form des Befestigungsbereiches der Nadeln entspricht, d.h. diese Abstandshalteteile können in der gleichen einfachen Weise aufgeschoben und aufgereiht werden.To form a pinstripe or stick with optimally spaced Spacers can be provided in the axial direction, whose shape corresponds approximately to the shape of the fastening area of the needles, i.e. these spacers can be done in the same simple To be postponed and lined up.

Wenngleich es im Rahmen der erfindungsgemäßen Ausgestaltung nicht erforderlich ist, kann der Befestigungsbereich der Nadeln wenigstens teilweise in einen Kunststoffkörper eingebettet sein, so daß eine Art Nadelstreifen herkömmlicher Art geschaffen wird, wobei trotz der zusätzlichen Maßnahme des Kunststoffvergießens gleichwohl der Vorteil einer extrem einfachen Befestigung an dem Tragestab und in der Maschine realisierbar ist.Although not necessary in the context of the configuration according to the invention the fastening area of the needles can be at least partially be embedded in a plastic body, so that a kind of pinstripe conventional type is created, despite the additional Plastic molding measure nevertheless the advantage of an extreme easy to attach to the carrying bar and in the machine is.

Bei der letztgenannten Ausführungsform kann der Kunststoffkörper zwischen zwei benachbarten Nadeln einen Abstandsbereich ausbilden.In the latter embodiment, the plastic body between form two adjacent needles a spacing area.

Die Erfindung richtet sich auch auf ein Verfahren zum Aufbringen bzw. Auswechseln einer Garnitur aus Nadeln der vorstehend beschriebenen Art, wobei vorgesehen ist, daß die Nadeln durch den Nadelhersteller auf ein Konfektionierungsrohr aufgeschoben werden, welches im Querschnitt etwa dem Tragestab entspricht, der in die Kämm-Maschien eingesetzt wird, wobei der Kämm-Maschinenbetreiber zum Aufbringen der Garnitur, gegebenenfalls nach Entfernen der alten Garnitur, das Konfektionierungsrohr fluchtend an den zu garnierenden Tragestab ansetzt, so daß die Gesamtheit der für den jeweiligen Tragestab bestimmten Nadeln durch eine einzige Verschiebebewegung aufgebracht werden kann. Es ist dann lediglich erforderlich, endseitige Sicherungen, z.B. in Form von Schrauben, aufzubringen und der Tragestab kann sofort wieder verwendet werden.The invention also relates to a method for applying or Replacement of a set of needles of the type described above, it is provided that the needles by the needle manufacturer on a Assembly tube are pushed on, which in cross section approximately corresponds to the carrying rod which is inserted into the combing machines, whereby the Kämm machine operator to apply the clothing, if necessary after removing the old set, the assembly tube is aligned attaches to the support rod to be garnished, so that the whole the needles for the respective carrying rod by a single one Sliding movement can be applied. It is then only necessary end fuses, e.g. in the form of screws and the carrying stick can be used again immediately.
