Description

Die Erfindung betrifft eine Garnitur und einen Deckelstab für eine textile Verarbeitungsmaschine.The invention relates to a clothing and a flat rod for a textile processing machine.

Karden haben unter anderem die Aufgabe, Faserflocken bis zur Einzelfaser, sowie die Nissen aufzulösen. Hierzu werden die Faserflocken zwischen einem Tambour und einem Wanderdeckel geleitet, wobei die Fasern ausgerichtet und vereinzelt werden. Der Tambour ist hierzu üblicherweise mit einer umlaufenden Sägezahngarnitur ausgestattet, bei denen aus einem Flachdraht mittels Stanzen einzelne Zähne herausgearbeitet werden. Der Wanderdeckel besteht üblicherweise aus vielen Deckelstäben mit flexiblen Garnituren, bei denen in elastischen Gewebeeinlagen eine Vielzahl von einzelnen Drähten befestigt werden, deren Spitzen in sehr engem Abstand mit den Spitzen der Sägezahngarnitur des Tambours korrespondieren und damit den Kardierspalt bilden.Amongst other things, carding machines have the task of dissolving fiber flakes down to the individual fiber, as well as the nits. For this purpose, the fiber flakes are passed between a spool and a revolving lid, the fibers are aligned and separated. For this purpose, the tambour is usually equipped with a circumferential saw tooth set, in which individual teeth are produced from a flat wire by means of punching. The revolving lid usually consists of many flat bars with flexible sets in which a plurality of individual wires are attached in elastic fabric inserts, the tips of which correspond at very close distance with the tips of the sawtooth of the main cylinder and thus form the carding gap.

Um die engen Kardierspalte über eine lange Laufzeit der Karde sicher zu gewährleisten, müssen alle zugehörigen Bauteile eine hohe Präzision aufweisen. Insbesondere durch den Verschleiß und den Austausch der flexiblen Garnituren können sich beim Nachschleifen und der erneuten Montage an den Deckelstab unerwünschte Ungenauigkeiten ergeben. Weiterhin sind die flexiblen Garnituren sehr teuer in der Herstellung mit dem weiteren Nachteil, dass sie sich nur begrenzt Nachschleifen lassen. Ein weiterer Nachteil ist, dass die gesamten Deckelstäbe einschließlich der Garnitur demontiert und in der Schleifmaschine bearbeitet werden müssen, da nur so die einbaufertige Toleranz unter 0,1 mm gehalten werden kann.In order to ensure the tight carding gaps safely over a long battery life, all associated components must have high precision. In particular, the wear and replacement of the flexible sets may result in regrinding and reassembly of the flat bar unwanted inaccuracies. Furthermore, the flexible trimmings are very expensive to manufacture with the further disadvantage that they allow only limited regrinding. Another disadvantage is that the entire flat bars including the set must be dismantled and machined in the grinding machine, because only so the ready-to-install tolerance can be kept below 0.1 mm.

In der DE 102009013412 A1 wird eine flexible Garnitur für einen Deckelstab beschrieben, die mittels Magnet am Deckelstab befestigbar ist. Nachteilig ist die aufwendige Gestaltung der Garnitur, bei dem der Garniturstreifen erst auf einem Blechstreifen aufgeklebt wird, um dann magnetisch in einer Ausnehmung des Deckelstabes befestigt zu werden. Ein weiterer Nachteil ist die Verwendung der Häkchen, die aufwendig in einem Gewebekörper eingearbeitet sind und die nur eine begrenzte und aufwändige Anzahl von Nachschliffen zulässt.In the DE 102009013412 A1 is described a flexible set for a flat bar, which is fastened by means of magnet on the flat bar. A disadvantage is the complex design of the clothing, in which the clothing strip is glued only on a metal strip, to then be magnetically fixed in a recess of the flat bar. Another disadvantage is the use of the hook, which are elaborately incorporated in a fabric body and which allows only a limited and complex number of regrinds.

In der US 3,793,677 wird die Befestigung einer Garnitur an einem Deckelstab beschrieben, bei dem die Sägezahndrähte in einem ausgehärteten Kunststoff bis zu den Zähnen eingebettet sind.In the US 3,793,677 the attachment of a garnish is described on a flat bar, in which the sawtooth wires are embedded in a cured plastic to the teeth.

Die EP 0043868 A1 offenbart die Befestigung von Garniturendrähten an einem u-förmigen Blech mittels einer Kehlnaht, wobei die Schweißnaht an den Stirnflächen der Garniturendrähte angeordnet ist und später, zur Erzielung einer ebenen Kontur, zumindest teilweise abgeschliffen wird.The EP 0043868 A1 discloses the attachment of garniture wires to a U-shaped sheet metal by means of a fillet weld, wherein the weld seam is arranged on the end faces of the garniture wires and is later at least partially ground to obtain a flat contour.

In der CH 654341 werden die Garniturendrähte über ihre gesamte Länge am Fuß mit einem daneben angeordneten Garniturendraht verlötet oder verschweißt.In the CH 654341 The clothing wires are soldered or welded over their entire length on the foot with a clothing wire arranged next to it.

Auch die EP 0067599 A1 offenbart die Befestigung von Garniturendrähten mittels Klebeband am Fußbereich der Garnitur.Also the EP 0067599 A1 discloses the attachment of garment wires by means of tape at the foot of the clothing.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, einen preiswerten und präzise herstellbaren Garniturstreifen zu schaffen.Based on this prior art, it is an object of the invention to provide an inexpensive and precisely producible clothing strip.

Die Erfindung löst diese Aufgabe mit den Merkmalen von Anspruch 1 und 3; weitere vorteilhafte Ausgestaltungen sind durch die Unteransprüche gekennzeichnet.The invention solves this problem with the features of claims 1 and 3; Further advantageous embodiments are characterized by the subclaims.

Gemäß der technischen Lehre umfasst der Garniturstreifen zur Verwendung in einer textilen Verarbeitungsmaschine eine Vielzahl vonAccording to the technical teaching, the clothing strip for use in a textile processing machine comprises a plurality of

Zahnsegmenten mit jeweils mehreren Zähnen, die jeweils einen Zahnkopf und einen Zahnfuß aufweisen, wobei die Zahnsegmente parallel zueinander angeordnet und direkt oder indirekt miteinander verbunden sind.Tooth segments, each having a plurality of teeth, each having a tooth tip and a tooth root, wherein the tooth segments are arranged parallel to each other and directly or indirectly connected to each other.

Die Erfindung ist dadurch gekennzeichnet, dass die Verbindung der Zahnsegmente stoffschlüssig erfolgt, wodurch die Zahnsegmente untereinander völlig spielfrei sind.The invention is characterized in that the connection of the tooth segments takes place cohesively, whereby the tooth segments are completely free of play with each other.

Die stoffschlüssige Verbindung, beispielsweise durch eine Laser- oder Schutzgasschweißung, ermöglicht eine weitestgehend automatische Fertigung der Garniturstreifen, die um ein vielfaches schneller und präziser erfolgt, als die Herstellung der Garnituren, bei denen die Häkchen in einen Gewebekörper eingesetzt werden.The cohesive connection, for example, by a laser or inert gas welding, allows a largely automatic production of clothing strips, which is much faster and more accurate than the production of trimmings in which the prongs are inserted into a fabric body.

Dabei weisen die Zahnsegmente zur direkten Verbindung mindestens eine Nut auf, innerhalb der die stoffschlüssige Verbindung angeordnet ist. Durch die Nut wird die äußere Kontur der Zahnsegmente nicht verändert. Gleichzeitig hat die Schweißnaht eine höhere Dauerfestigkeit, als eine flächig aufgebrachte Schweißnaht, die anschließend zum Teil abgeschliffen wird.In this case, the toothed segments for direct connection at least one groove, within which the cohesive connection is arranged. Through the groove, the outer contour of the tooth segments is not changed. At the same time, the weld has a higher fatigue strength than a surface-applied weld, which is then partially ground off.

Weiterhin kann die mindestens eine Nut im Bereich des Zahnfußes angeordnet sein, wodurch sich eine nur geringe Wärmebelastung auf die gehärteten Zahnköpfe ergibt.Furthermore, the at least one groove can be arranged in the region of the tooth root, which results in only a slight heat load on the hardened tooth heads.

Eine indirekte Verbindung der Zahnsegmente miteinander kann über einen Blechstreifen erfolgen, an den die Zahnsegmente durch mehrere Schweißnähte verbunden werden. Der Blechstreifen ermöglicht ein flexibleres und flächiges Anlegen an eine Befestigung innerhalb des Deckelstabes und eine hohe Toleranzgenauigkeit des Garniturstreifens. Um eine höchst mögliche Flexibilität zu erreichen, ist darauf zu achten, dass bei dieser indirekten Verbindung die Zahnsegmente nicht miteinander verschweißt sind, sondern nur am Blechstreifen befestigt sind.An indirect connection of the tooth segments with each other can be done via a metal strip to which the tooth segments are connected by a plurality of welds. The metal strip allows a more flexible and planar application to a fixture within the flat bar and a high tolerance accuracy of the clothing strip. In order to achieve the highest possible flexibility, it should be ensured that in this indirect connection, the toothed segments are not welded together, but are only attached to the metal strip.

Die Schweißnähte sind in Längsrichtung des Garniturstreifens angeordnet, weisen eine begrenzte Länge auf, und sind versetzt zueinander angeordnet. Der Garniturstreifen wird damit flexibel und kann mit einem Minimum an Nacharbeit flächig innerhalb des Deckelstabes anliegen. Dabei kann es vorteilhaft sein, wenn die Zahnsegmente im Bereich der Schweißnähte versetzt angeordnete Nuten aufweisen. Durch eine abwechselnde Anordnung der Nuten wird nur jedes zweite Zahnsegment mit dem Blechstreifen über diese Schweißnaht verbunden, so dass nebeneinander angeordnete Zahnsegmente nicht gleichzeitig mit der gleichen Schweißnaht am Blechstreifen befestigt werden. Hiermit wird eine Verbindung der Zahnsegmente untereinander verhindert. Der Blechstreifen ist zumindest in Längsrichtung so flexibel, dass er sich der Oberfläche eines Magneten mit einem geringen Aufwand an Nacharbeit anpassen kann.The welds are arranged in the longitudinal direction of the clothing strip, have a limited length, and are offset from one another. The clothing strip is thus flexible and can rest flat with a minimum of rework within the flat bar. It may be advantageous if the toothed segments have offset grooves in the region of the welds. By an alternate arrangement of the grooves only every second toothed segment is connected to the metal strip over this weld, so that juxtaposed tooth segments are not fastened at the same time with the same weld on the sheet metal strip. This prevents a connection of the tooth segments with each other. The metal strip is so flexible at least in the longitudinal direction that it can adapt to the surface of a magnet with a small amount of rework.

Vorteilhafterweise können sich die Schweißnähte in Längsrichtung des Garniturstreifens zumindest teilweise überlappen, wodurch der Garniturstreifen flexibel wird.Advantageously, the welds in the longitudinal direction of the clothing strip can at least partially overlap, whereby the clothing strip is flexible.

Eine weitere Reduzierung der Steifigkeit wird dadurch erreicht, dass der Blechstreifen orthogonal zu seiner Längsrichtung mindestens einen Schlitz aufweist. Dabei können sich die Schlitze nur über einen Teilbereich der Breite des Blechstreifens erstrecken.A further reduction of the rigidity is achieved in that the metal strip has at least one slot orthogonal to its longitudinal direction. The slots can extend only over a portion of the width of the sheet metal strip.

Ein Deckelstab für eine textile Verarbeitungsmaschine umfasst eine Ausnehmung zur Aufnahme eines Garniturstreifens, der eine Vielzahl von Zahnsegmenten umfasst, die mittels magnetischer Kraft am Deckelstab befestigbar sind. Damit wird eine leichte Montage bzw. Demontage des Garniturstreifens vom Deckelstab ermöglicht, der damit beim Austausch oder Nachschleifen des Garniturstreifens in der Spinnerei verbleiben kann. Über die magnetische Verbindung von Garniturstreifen mit dem Deckelstab kann hochpräzise unter Einhaltung kleinster Toleranzen eine Schärfung der Zahnspitzen erfolgen. Die Oberseite des Garniturstreifens liegt flächig am Magneten im Deckelstab an, so dass keine Montageungenauigkeiten vorkommen können. Weiterhin ist die Oberseite des Garniturstreifens Referenzpunkt für die Schleifmaschine, die im Gegensatz zu den elastischen Häkchengarnituren die nötige Festigkeit aufweist und während des Schleifvorganges nicht nachfedert.A flat rod for a textile processing machine comprises a recess for receiving a clothing strip, which comprises a plurality of tooth segments, which can be fastened by means of magnetic force on the flat rod. Thus, an easy assembly or disassembly of the clothing strip is made possible by the flat bar, the so when replacing or Regrinding the clothing strip may remain in the spinning mill. About the magnetic connection of clothing strip with the flat bar can Precision tightening of the tips of the teeth can be carried out with high precision while maintaining the smallest tolerances. The top of the clothing strip is flat on the magnet in the flat bar, so that no assembly inaccuracies can occur. Furthermore, the top of the clothing strip reference point for the grinding machine, which in contrast to the elastic crochet sets has the necessary strength and does not rebound during the grinding process.

Dadurch, dass mindestens ein Zahnsegment eine Feder aufweist, mit der eine formschlüssige Verbindung mit dem Deckelstab herstellbar ist, können Kraftspitzen beim Kardieren die magnetische Verbindung nicht lösen. Die am Zahnsegment integrierte Feder ermöglicht eine genaue Montage des Garniturstreifens am Deckelstab ohne weitere mechanische Bauteile, da die Feder in einem Arbeitsgang bei der Herstellung der Zähne mit aus dem Flachdraht oder einem profilierten Draht heraus gestanzt wird.Characterized in that at least one toothed segment has a spring with which a positive connection with the flat bar can be produced, force peaks during carding can not solve the magnetic connection. The integrated on the sector gear spring allows accurate mounting of the clothing strip on the flat bar without additional mechanical components, since the spring is punched in one operation in the manufacture of teeth with out of the flat wire or a profiled wire out.

Ein bekannter Deckelstab 1 nach dem Stand der Technik ist in Figur 1 in Seitenansicht dargestellt. Der Deckelstab 1 umfasst einen hier nicht dargestellten Deckelkopf, der mit seiner Geometrie eine gewisse Steifigkeit erzeugt und damit über die Breite eines Tambours einer Karde oder einer Krempel mit dessen Sägezahngarnitur einen konstanten Kardierspalt erzeugt. Am Deckelfuß 1a bilden zwei beidseitig angeordnete Stege 1b, 1c eine Ausnehmung 1d, die geeignet ist, mindestens eine Deckelgarnitur 4 aufzunehmen. Die Ausnehmung 1d nach diesem Beispiel ist zweistufig ausgeführt, so dass ein Magnet 3 über eine Befestigung 2 mit dem Deckelstab 1 fest verbunden ist. Die Befestigung 2 kann als Klebeverbindung oder sonstige stoffschlüssige Verbindung, oder auch als mechanische Verbindung ausgeführt sein. Die Deckelgarnitur 4 umfasst im Wesentlichen ein Tragelement 6, das die Häkchen 7 aufnimmt, und ein Stahlblech 5, das mit dem Tragelement 6 verbunden ist. Das Tragelement 6 ist üblicherweise aus einem textilen Gebilde oder einem Gewebekörper gebildet, in dem die Vielzahl der Häkchen dicht an dicht integriert ist. Das Stahlblech 5 wird mittels magnetischer Kraft am Magneten 3 gehalten. Die Häkchen 7 zeigen mit ihrer Spitze auf den Tambour und bilden mit den nicht dargestellten Zähnen der Sägezahngarnitur den Kardierspalt.A known prior art flat bar 1 is shown in FIG FIG. 1 shown in side view. The flat bar 1 comprises a lid head, not shown here, which generates a certain stiffness with its geometry and thus generates a constant carding gap across the width of a drum of a card or a carding machine with its sawtooth set. On the cover foot 1a, two webs 1b, 1c arranged on both sides form a recess 1d, which is suitable for receiving at least one flat clothing 4. The recess 1d according to this example is designed in two stages, so that a magnet 3 is fixedly connected via an attachment 2 with the flat rod 1. The attachment 2 can be designed as an adhesive bond or other cohesive connection, or as a mechanical connection. The flat cover 4 essentially comprises a support element 6, which receives the hooks 7, and a steel sheet 5, which is connected to the support element 6. The support element 6 is usually formed from a textile structure or a fabric body, in which the plurality of hooks is tightly integrated. The steel sheet 5 is held by means of magnetic force on the magnet 3. The check marks 7 point with their tip on the spool and form the Kardierspalt with the teeth of the saw tooth set, not shown.

Erfindungsgemäß besteht jeder Garniturstreifen 8 nach Figur 2 aus einer Vielzahl von Zahnsegmenten 10, die hintereinander aufgereiht sind. Jedes Zahnsegment 10 besteht aus mehreren Zähnen 13 mit jeweils einem Zahnkopf 11 und einem Zahnfuß 12. Die Zahnköpfe 11 sind gegen die Rotationsrichtung des nicht dargestellten Tambours gegen die zu kämmenden Fasern gerichtet. Nach dem Ausführungsbeispiel von Figur 2 ist im Bereich des Zahnfußes 12 an jedem Zahnsegment 10 mindestens eine Nut 14 bzw. Vertiefung eingearbeitet, die zur Aufnahme einer Schweißnaht 15 dient. Ein Garniturstreifen 8 umfasst damit eine Vielzahl von aneinander gereihten und miteinander verschweißten Zahnsegmenten 10, wobei die Schweißnaht 15 parallel zur Längsachse des Deckelstabes 1 angeordnet ist. Die Zahnsegmente 10 sind direkt über eine Schweißnaht 15 miteinander verbunden. In diesem Ausführungsbeispiel sind zwei zueinander beabstandete Nuten 14 angeordnet, so dass sich nach einem Verschweißen die Zahnsegmente 10 nicht mehr gegeneinander verziehen bzw. verdrehen können. An einer Seite des Garniturstreifens 8 kann eine Verlängerung in Form einer Feder 9 angeordnet sein, die in eine korrespondierende Nut 1e des Deckelstabes 1 eingreift. Die Garniturstreifen 8 bestehen aus einer Vielzahl von Zahnsegmenten 10, die hintereinander angeordnet und miteinander verbunden sind. Jedes Zahnsegment 10 kann aus einem Stück gestanztem Sägezahndraht oder einem profilierten Draht mit einem Zahnkopf 11 und einem Zahnfuß 12 bestehen.According to the invention, each clothing strip 8 follows FIG. 2 from a plurality of toothed segments 10, which are lined up one behind the other. Each toothed segment 10 consists of a plurality of teeth 13 each having a tooth head 11 and a tooth root 12. The tooth heads 11 are directed against the direction of rotation of the main cylinder, not shown, against the fibers to be combed. According to the embodiment of FIG. 2 is in the region of the tooth root 12 on each toothed segment 10 at least a groove 14 or recess is incorporated, which serves to receive a weld 15. A clothing strip 8 thus comprises a multiplicity of toothed segments 10 lined up with each other and welded together, wherein the weld seam 15 is arranged parallel to the longitudinal axis of the flat rod 1. The toothed segments 10 are connected to each other directly via a weld 15. In this embodiment, two mutually spaced grooves 14 are arranged so that the tooth segments 10 can no longer warp or twist after welding. On one side of the clothing strip 8, an extension in the form of a spring 9 can be arranged, which engages in a corresponding groove 1e of the flat rod 1. The clothing strip 8 consist of a plurality of toothed segments 10, which are arranged one behind the other and connected to each other. Each sector gear 10 may consist of one piece punched sawtooth wire or a profiled wire with a tooth tip 11 and a tooth root 12.

Im nicht erfindungsgemäßen Ausführungsbeispiel der Figur 3 sind die Zahnsegmente mit versetzt angeordneten Zähnen 13, 13a ausgeführt, wobei der Versatz der Zähne 13, 13a sich über die gesamte Länge des Garniturstreifens 8 bzw. Deckelstabes 1 wiederholen kann. In diesem Ausführungsbeispiel wird mindestens eine Schweißnaht 15 auf die obere Fläche der Zahnsegmente 10 aufgebracht, die damit die Oberseite 16 des Garniturstreifens 8 bildet. Die Zahnsegmente 10 sind direkt über eine Schweißnaht 15 miteinander verbunden.In the non-inventive embodiment of FIG. 3 the toothed segments are executed with staggered teeth 13, 13a, wherein the offset of the teeth 13, 13a can be repeated over the entire length of the clothing strip 8 or flat rod 1. In this embodiment, at least one weld 15 is applied to the upper surface of the toothed segments 10, which thus forms the upper side 16 of the clothing strip 8. The toothed segments 10 are connected to each other directly via a weld 15.

In dem Ausführungsbeispiel der Figur 4 wird zur Herstellung des Garniturstreifens 8 ein Blechstreifen 17 verwendet, der in seiner Länge im Wesentlichen der Länge des Deckelstabes 1 entspricht. Unter dem Blechstreifen 17 sind eine Vielzahl von Zahnsegmenten 10 angeordnet, die mit dem Blechstreifen 17 stoffschlüssig verbunden werden. Die Zahnsegmente 10 werden mit ihrem Zahnfuß 12 unter den Blechstreifen 17 positioniert. In einer nicht dargestellten Vorrichtung oder Kassette können die Zahnsegmente 10 entsprechend der Länge des Deckelstabes 1 aufgereiht werden. Der Blechstreifen 17 wird auf die Zahnfüsse 12 positioniert und stoffschlüssig mit den Zahnsegmenten 10 verbunden. Als bevorzugte Verbindungsart wird ein Schweißverfahren verwendet, beispielsweise Laserschweißen, mit dem eine stoffschlüssige Verbindung zwischen den Zahnsegmenten 10 und dem Blechstreifen 17 hergestellt wird. Aufgrund der stoffschlüssigen Verbindung bildet die vom Zahnfuß 12 abgewandte Seite des Blechstreifens 17 die Oberseite 16 des Garniturstreifens 8. Der Blechstreifen 17 kann aus Federstahl hergestellt werden und soll sich möglichst flexibel der Oberfläche des Magneten 3 anpassen, um sich flächenbündig anzulegen. Die Zahnsegmente 10 sind über den Blechstreifen 17 mittels mehrerer Schweißnähte 19 indirekt miteinander verbunden.In the embodiment of FIG. 4 For the production of the clothing strip 8, a sheet metal strip 17 is used which corresponds in its length substantially to the length of the flat bar 1. Below the metal strip 17, a plurality of toothed segments 10 are arranged, which are materially connected to the sheet metal strip 17. The tooth segments 10 are with their tooth base 12 under the metal strip 17 positioned. In a device or cassette, not shown, the toothed segments 10 can be lined up according to the length of the flat bar 1. The sheet metal strip 17 is positioned on the toothed feet 12 and connected to the toothed segments 10 with a material fit. As a preferred type of connection, a welding method is used, for example laser welding, with which a cohesive connection between the toothed segments 10 and the sheet metal strip 17 is produced. Due to the cohesive connection, the side remote from the tooth root 12 of the metal strip 17 forms the top 16 of the clothing strip 8. The metal strip 17 can be made of spring steel and should be as flexible as possible to adapt to the surface of the magnet 3 in order to fit flush. The toothed segments 10 are indirectly connected to each other via the metal strip 17 by means of a plurality of welds 19.

In Figur 5 ist die Draufsicht auf die Oberseite 16 eines Blechstreifens 17 dargestellt, bei dem eine Vielzahl von Zahnsegmenten 10 unter dem Blechstreifen 17 quer zur Längsrichtung des Deckelstabes angeordnet sind. Aus Gründen der Darstellung sind nur fünf Zahnsegmente 10 unter dem Blechstreifen 17 dargestellt. In dem Ausführungsbeispiel der Figur 5 sind die Zahnfüsse 12 mittels Laserschweißen mit dem Blechstreifen 17 verbunden, wobei die Schweißnähte 19, die hier nur symbolisch angedeutet sind, sich in einfacher nicht erfindungsgemäßer Ausführungsform ohne Unterbrechung über die gesamte Länge des Blechstreifens 17 erstrecken können. Dabei sind bevorzugt mindestens zwei Schweißnähte 19 parallel zueinander angeordnet, die jedes Zahnsegment 10 mit dem Blechstreifen 17 verbinden. In Abhängigkeit vom Schweißverfahren (Widerstandsschweißen, MIG-, MAG-Schweißverfahren, Laserschweißen) kann es notwendig sein, den Blechstreifen 17 entlang der geplanten Schweißnaht 19 mit einer schmalen Längsnut (nicht dargestellt) zu versehen, die während des Schweißvorganges mit dem Schweißgut zumindest teilweise aufgefüllt wird.In FIG. 5 is the plan view of the top 16 of a metal strip 17 shown, in which a plurality of toothed segments 10 are arranged below the metal strip 17 transverse to the longitudinal direction of the flat bar. For the sake of illustration, only five tooth segments 10 are shown below the sheet metal strip 17. In the embodiment of FIG. 5 the toothed feet 12 are connected by laser welding to the sheet metal strip 17, wherein the welds 19, which are only symbolically indicated here, can extend in a simple non-inventive embodiment without interruption over the entire length of the sheet metal strip 17. In this case, at least two weld seams 19 are preferably arranged parallel to one another, which connect each toothed segment 10 to the sheet metal strip 17. Depending on the welding process (resistance welding, MIG, MAG welding, laser welding), it may be necessary to provide the sheet metal strip 17 along the planned weld 19 with a narrow longitudinal groove (not shown), the is at least partially filled during the welding process with the weld metal.

In diesem Ausführungsbeispiel erstrecken sich die Schweißnähte 19 nur über eine bestimmte Länge des Blechstreifens 17 und überlappen sich dabei teilweise mit jeweils zwei weiteren Schweißnähten 19, so dass eine begrenzte Anzahl von Zahnsegmenten 10 mit vier Schweißnähten mit dem Blechstreifen 17 verbunden sind, alle anderen Zahnsegmente 10 nur mit zwei Schweißnähten 19. In Längsrichtung des Deckelstabes ergibt sich damit eine Flexibilität des Blechstreifens 17, der sich dadurch dem Magneten besser anpasst, was den Vorteil hat, dass im Gegensatz zum Ausführungsbeispiel der Figur 2 oder 3 die Oberseite 16 mit einer geringeren Präzision bearbeitet werden kann. Ein guter Kompromiss aus wirtschaftlicher Herstellung und möglichst hoher Flexibilität des Blechstreifens 17 wird erreicht, wenn die Schweißnähte nicht über die gesamte Länge des Deckelstabes 1 durchgehen, sondern nur eine begrenzte Länge aufweisen und versetzt zueinander angeordnet sind. Durch diese begrenzte Steifigkeit kann die notwendige Nacharbeit der Oberseite 16 reduziert werden, wobei sich der Garniturstreifen 8 flächenbündig an den Magneten 3 anlegen kann.In this embodiment, the welds 19 extend only over a certain length of the sheet metal strip 17 and partially overlap each with two other welds 19, so that a limited number of tooth segments 10 are connected with four welds with the metal strip 17, all other tooth segments 10th only with two welds 19. In the longitudinal direction of the flat rod results in a flexibility of the metal strip 17, which thereby better adapts to the magnet, which has the advantage that, in contrast to the embodiment of FIG. 2 or 3 the top 16 can be machined with less precision. A good compromise of economic production and the highest possible flexibility of the metal strip 17 is achieved when the welds do not pass over the entire length of the flat bar 1, but have only a limited length and are offset from one another. Due to this limited rigidity, the necessary reworking of the upper side 16 can be reduced, with the clothing strip 8 being able to rest flush against the magnet 3.

Eine noch größere Flexibilität des Blechstreifens 17 als Trägermaterial für die Zahnsegmente kann erreicht werden, wenn in dem Blechstreifen 17 parallel zur Anordnung der Zahnsegmente 10 und damit quer oder orthogonal zur Längsrichtung des Deckelstabes Schlitze 18 angeordnet sind. Nach Figur 6 erstrecken sich die Schlitze 18 nur über einen Teilbereich der Breite des Blechstreifens 17, so dass einerseits die notwendige Stabilität des Blechstreifens 17 als Tragkörper nicht gefährdet ist, andererseits aber eine ausreichende Flexibilität erzeugt wird, und sich dadurch die Oberseite 16 des Garniturstreifens 8 der Oberfläche des Magneten 3 mit einem Minimum an Nacharbeit anpassen kann. Weiterhin können sich die Schlitze 18 - ähnlich wie die Schweißnähte 19 - zumindest teilweise über ihre Länge überlappen. In diesem Ausführungsbeispiel überschneiden sich die Schlitze 18 nicht mit den Schweißnähten 19, was aber durchaus möglich sein kann.An even greater flexibility of the metal strip 17 as a carrier material for the tooth segments can be achieved if slits 18 are arranged in the sheet metal strip 17 parallel to the arrangement of the tooth segments 10 and thus transversely or orthogonally to the longitudinal direction of the flat bar. To FIG. 6 extend the slots 18 only over a portion of the width of the metal strip 17 so that on the one hand the necessary stability of the metal strip 17 is not endangered as a support body, but on the other hand sufficient flexibility is generated, and thereby the top 16 of the clothing strip 8 of the surface of Magnet 3 can adapt with a minimum of rework. Furthermore, the slots 18 - similar to the welds 19 - overlap at least partially over their length. In this embodiment, the slots 18 do not overlap with the welds 19, but this may well be possible.

Grundsätzlich wird die höchste Flexibilität in Längsrichtung des Garniturstreifens 8 dadurch erreicht, indem die Zahnsegmente 10 durch das Schweißverfahren nicht miteinander verbunden sind, sondern nur mit dem Blechstreifen 17 verschweißt sind.In principle, the highest flexibility in the longitudinal direction of the clothing strip 8 is achieved by the toothed segments 10 are not connected to each other by the welding process, but are only welded to the sheet metal strip 17.

Je nach Schweißverfahren, Vorrichtung und in Abhängigkeit davon, ob die Zahnsegmente 10 mit oder ohne Blechstreifen 17 verschweißt werden, kann entsprechend Figur 7 und 8 die Ausrichtung der Zahnsegmente 10 zueinander nicht parallel erfolgen, sondern in einem vorbestimmten Winkel α. Die Zahnfüße 12 berühren sich nur im untersten Punkt und gehen zum Zahnkopf 11 hin auseinander. Während bzw. nach dem Verschweißen der Zahnsegmente 10 miteinander, indem auf der Oberseite 16 der Zahnsegmente 10 eine Schweißnaht 15 gelegt wird, richten sich die Zahnsegmente 10 aufgrund des Verzuges in der Schweißnaht 15 zueinander aus (Fig. 8), so dass sich diese danach parallel zueinander anordnen und sich im Bereich des Zahnfußes 12 ganzflächig berühren. Der Winkel α, der nach dem Verschweißen 0° beträgt, ist unter anderem vom Schweißverfahren und von der Größe der Schweißnaht 15 abhängig und kann für jeden Garniturstreifen 8 bei der Vormontage eingestellt werden. Die Einstellung des richtigen Winkels α kann mittels nicht dargestellter Zwischenstücke in einer Vorrichtung erfolgen, die zwischen den Zahnköpfen 11 angeordnet werden. Die nicht dargestellte Vorrichtung kann eine gekrümmte Oberfläche aufweisen, auf die die Zahnsegmente 10 mit ihrer Oberseite 16 hintereinander angeordnet werden. Die Krümmung der Oberfläche korrespondiert mit dem Winkel α und dem erwarteten Verzug der Schweißnaht 15. Als Schweißverfahren können insbesondere Schutzgas- oder Laserschweißverfahren verwendet werden, die unter anderem eine automatisierte Fertigung ermöglichen.Depending on the welding method, apparatus and depending on whether the toothed segments 10 are welded with or without metal strips 17, can accordingly FIGS. 7 and 8 the alignment of the toothed segments 10 are not parallel to each other, but α at a predetermined angle. The feet 12 touch only at the lowest point and go to the tooth head 11 apart. During or after the welding of the toothed segments 10 with one another by placing a weld seam 15 on the upper side 16 of the toothed segments 10, the toothed segments 10 are aligned with each other due to the distortion in the weld seam 15 (FIG. Fig. 8 ), so that they then arrange parallel to each other and touch in the area of the tooth root 12 over the entire surface. The angle α, which is 0 ° after welding, depends inter alia on the welding method and the size of the weld 15 and can be set for each clothing strip 8 during pre-assembly. The adjustment of the correct angle α can take place by means of unillustrated intermediate pieces in a device, which are arranged between the tooth heads 11. The device, not shown, may have a curved surface on which the toothed segments 10 are arranged with their top 16 in a row. The curvature of the surface corresponds to the angle α and the expected distortion of the weld seam 15. In particular inert gas or Laser welding can be used, which enable, among other things, an automated production.

Nach dem Verschweißen und einer möglichen weiteren Wärmebehandlung des Garniturstreifens 8 wird die Oberseite 16 des Garniturstreifens 8 überfräst und/oder geschliffen und der Fläche des Magneten 3 exakt angepasst. Insbesondere die Höhe des Garniturstreifens 8 von der Oberseite 16 bis zur Spitze jedes Zahnes 13 ist exakt einstellbar, so dass durch einen schnellen Austausch der Garniturstreifen der Deckelstab 1 schnell gewartet werden kann. Die nebeneinander aufgereihten und verschweißten Zahnsegmente 10 bieten im Vergleich zu den Häkchen den Vorteil, dass die Zahnsegmente 10 untereinander spielfrei verbunden sind.After welding and a possible further heat treatment of the clothing strip 8, the upper side 16 of the clothing strip 8 is milled and / or ground and exactly adapted to the surface of the magnet 3. In particular, the height of the clothing strip 8 from the upper side 16 to the tip of each tooth 13 is precisely adjustable, so that the flat bar 1 can be quickly maintained by a quick replacement of the clothing strips. The juxtaposed and welded toothed segments 10 offer in comparison to the hooks the advantage that the toothed segments 10 are connected to each other without play.

Nach der Erfindung ist eine effiziente und preiswerte Herstellung der Garniturstreifen 8 möglich. Weiterhin ermöglicht die Erfindung eine einfache Montage der Garniturstreifen 8 in den Deckelstab 1, so dass ein schneller und präziser Austausch verschlissener Garniturstreifen 8 gewährleistet ist, ohne den Deckelstab 1 zu demontieren. Ein besonders wichtiger Vorteil ist die präzise Nachschleifbarkeit und Montage des Garniturstreifens 8, ohne den Deckelstab 1 demontieren zu müssen. Es lassen sich damit sehr geringe Toleranzen am Kardierspalt einhalten.According to the invention, an efficient and inexpensive production of clothing strips 8 is possible. Furthermore, the invention enables a simple assembly of the clothing strips 8 in the flat bar 1, so that a faster and more precise replacement of worn clothing strips 8 is ensured without disassembling the flat bar 1. A particularly important advantage is the precise regrinding and assembly of the clothing strip 8 without having to dismantle the flat bar 1. It can thus comply with very small tolerances on the carding gap.

Die Montage des Garniturstreifens 8 in die Deckelgarnitur 4 ist beispielhaft in Figur 9 dargestellt. In der Ausnehmung 1d zwischen den Stegen 1b und 1c ist ein Magnet 3 mittels einer Befestigung 2 angeordnet, wobei die Befestigung 2 als eine mechanische Verbindung zum Deckelfuß 1a ausgeführt sein kann, oder als stoffschlüssige Verbindung, beispielsweise als Klebeverbindung. Als Magnet 3 dienen vorzugsweise Permanentmagnete mit einer hohen magnetischen Koerzitivfeldstärke, wie beispielsweise Magnete mit einer Neodym-Eisen-Bor-Legierung oder aus einer Samarium-Cobalt-Legierung, bei denen die Gefahr der Entmagnetisierung bei Betriebstemperaturen über 50° Celsius gering ist.The assembly of the clothing strip 8 in the flat cover 4 is exemplary in FIG. 9 shown. In the recess 1d between the webs 1b and 1c, a magnet 3 is arranged by means of a fastening 2, wherein the attachment 2 can be designed as a mechanical connection to the cover foot 1a, or as cohesive connection, for example as an adhesive bond. As the magnet 3 are preferably permanent magnets with a high magnetic coercive force, such as magnets with a neodymium-iron-boron alloy or from a samarium-cobalt alloy, where the risk of demagnetization at operating temperatures above 50 ° Celsius is low.

Der Garniturstreifen 8 wird mit seiner Oberseite 16 in die Ausnehmung 1d montiert, in dem die Feder 9 zuerst in die Nut 1e eingesetzt wird und der Garniturstreifen 8 um die Nut 1e in die Ausnehmung 1d gegen den Uhrzeigersinn gedreht bzw. gekippt wird. Die Zahnköpfe 11 weisen in ihrer Neigung dabei gegen die Rotationsrichtung des Tambours und sind dabei gegen die zu kardierenden Fasern gerichtet. Dabei besteht die Gefahr des Verkippens für den Garniturstreifen 8, da der erste Kraftangriffspunkt für den Kardiervorgang im Bereich des Steges 1b liegt. Durch den Formschluss zwischen Nut 1e und Feder 9 wird das Verkippen des Garniturstreifens 8 von der magnetischen Verbindung verhindert. Der Garniturstreifen 8 wird damit nicht nur kraftschlüssig, sondern auch formschlüssig im Deckelfuß 1a gehalten. Alternativ zu der Ausführungsform von Nut 1e und Feder 9 kann der Formschluss auch durch andere Mittel, beispielsweise eine Schwalbenschwanzform, ein integriertes Befestigungsmittel oder eine äußere Abdeckung hergestellt werden.The clothing strip 8 is mounted with its upper side 16 in the recess 1 d, in which the spring 9 is first inserted into the groove 1 e and the clothing strip 8 is rotated or tilted around the groove 1 e in the recess 1 d counterclockwise. The tooth heads 11 have in their inclination against the direction of rotation of the spool and are directed against the fibers to be carded. There is a risk of tilting for the clothing strip 8, since the first force application point for the carding in the region of the web 1b is located. Due to the positive connection between the groove 1e and spring 9, the tilting of the clothing strip 8 is prevented by the magnetic connection. The clothing strip 8 is thus not only frictionally, but also positively held in the cover foot 1a. As an alternative to the embodiment of groove 1e and spring 9, the positive connection can also be produced by other means, for example a dovetail shape, an integrated fastening means or an outer cover.

Die Demontage des Garniturstreifens 8 erfolgt über nicht dargestellte Nuten im Bereich des Steges 1c, in die ein Werkzeug eingesetzt und mittels Hebelwirkung den Garniturstreifen 8 vom Magneten 3 lösen und in Uhrzeigerrichtung aus der Ausnehmung 1d heraus gehebelt werden kann.The dismantling of the clothing strip 8 via not shown grooves in the region of the web 1c, in which a tool used and solve by means of leverage the clothing strip 8 from the magnet 3 and can be levered out of the recess 1d out in the clockwise direction.
