Description

Die Erfindung betrifft einen zum Verbinden mit den Deckelstäben einer Karde bestimmten Kratzenbeschlag, der eine Vielzahl Zähne aufweisende, mit einem Trägerteil verbundene Drahtstreifen enthält.The invention relates to a scraper fitting intended to be connected to the flat bars of a card, which has a plurality of wire strips with teeth connected to a carrier part.

Die Karden dienen in der Textilindustrie dazu, Fasern zu öffnen, zu kämmen, zu reinigen. Bei den Wanderdeckelkarden ist hierzu ein drehbarer Kardenzylinder vorhanden, dessen Mantel mit einem Kratzenbeschlag versehen ist. Dieser wirkt mit einer Vielzahl relativ dazu bewegter ebenfalls mit einem Kratzenbeschlag versehenen Deckelstäbe zusammen. Bekannte Deckelstäbe weisen einen Träger auf, der den Kratzenbeschlag trägt. Dazu werden entweder in einen flexiblen Streifen eingesetzte Drähte oder auf einem starren Träger angeordnete Abschnitte, Streifen eines gezahnten Metalldrahtes verwendet.In the textile industry, the cards serve to open, comb, and clean fibers. The revolving flat cards have a rotatable card cylinder for this purpose, the jacket of which is provided with a scratch fitting. This interacts with a large number of flat bars which are also moved with respect to it and also provided with a scratch fitting. Known flat bars have a carrier which carries the scraper fitting. For this purpose either wires inserted into a flexible strip or sections arranged on a rigid support, strips of a toothed metal wire, are used.

Bei der Ausführung mit Streifen gezahnten Metalldrahtes werden gemäss des Standes der Technik leistenförmige Träger mit einer in Längsrichtung derselben verlaufenden Ausnehmung verwendet, in weicher Ausnehmung die Streifen des Metalldrahtes nebeneinander eingesetzt werden. Die Verbindung des Metalldrahtes mit dem Boden der Ausnehmung erfolgt mittels Klebstoff, oder z.B. wenn der Träger aus Kunststoff ist, werden die Metalldrähte beim Giessen desselben darin eingepresst. Die Verbindung des Trägers mit dem Stab erfolgt dann beispielsweise mittels Klebstoff oder mittels klammerförmiger Bauteile.In the embodiment with strips of toothed metal wire, strip-shaped carriers with a recess running in the longitudinal direction thereof are used according to the prior art, in a soft recess the strips of the metal wire are used next to one another. The metal wire is connected to the bottom of the recess by means of adhesive, or e.g. if the carrier is made of plastic, the metal wires are pressed into it when it is cast. The carrier is then connected to the rod, for example by means of adhesive or by means of clamp-shaped components.

Da die Ausnehmung offensichtlich nicht bis zum Längsrand des leistenförmigen Trägers verläuft, bestehen zwischen benachbarten Deckeln Leerstellen, in denen kein Kardieren stattfindet. Werden die Kratzendrähte in Kunststoffträger eingepresst oder ist Klebstoff zwischen dem jeweiligen Kratzendraht und dem Boden der Ausnehmung vorhanden wird die Ausrichtung der Kratzendrähte relativ zum Träger stark beeinträchtigt und mangelhaft, weil in beiden Fällen beim Einsetzen der Kratzendrähte diese auf eine nachgiebige Fläche abgelegt werden.Since the recess obviously does not extend to the longitudinal edge of the strip-shaped carrier, there are empty spaces between adjacent lids in which no carding takes place. If the scratch wires are pressed into the plastic carrier or there is adhesive between the respective scratch wire and the bottom of the recess, the orientation of the scratch wires relative to the carrier is severely impaired and deficient because in both cases when the scratch wires are inserted, they are placed on a flexible surface.

Ziel der Erfindung ist, die angeführten Nachteile zu beheben.The aim of the invention is to remedy the disadvantages mentioned.

Dieses Ziel wird erfindungsgemäss dadurch erreicht, dass der Träger ein gewalztes Eisenprofil ist, dass die Breite des Eisenprofils gleich der Länge des Drahtstreifens ist, und dass jeder Drahtstreifen bei seinen Enden an den Längsrandbereichen des Eisenprofils angeschweisst ist.This aim is achieved according to the invention in that the carrier is a rolled iron profile, that the width of the iron profile is equal to the length of the wire strip, and that each wire strip is welded at its ends to the longitudinal edge areas of the iron profile.

Bei einem bevorzugten Ausführungsbeispiel ist eine Mehrzahl Drahtstreifen mittels jeweils einer bei den Enden derselben verlaufenden Schweissraupe mit jeweiligen Längsbereichen verbunden. Dabei kann der zwischen den Schweissstellen gelegene Abschnitt des Drahtstreifens unmittelbar auf dem Trägerteil aufliegen.In a preferred exemplary embodiment, a plurality of wire strips are connected to respective longitudinal regions by means of a welding bead running at the ends thereof. The section of the wire strip located between the welding points can lie directly on the carrier part.

Der Trägerteil kann seinerseits ein Abschnitt eines Eisenprofils mit bügelförmiger Querschnittform sein, das einen Basisabschnitt und zwei davon abstehende Schenkelabschnitte aufweist, die jeweils mittels eines Bogenabschnittes mit dem Basisabschnitt und den Bogenabschnitten gebildet sein kann.The carrier part can in turn be a section of an iron profile with a bow-shaped cross-sectional shape, which has a base section and two leg sections projecting therefrom, which can each be formed by means of an arch section with the base section and the arch sections.

Weiter kann der Trägerteil mit einem weiteren, gewalzten Eisenprofil mit bügelförmiger Querschnittsform verbunden sein, das einen Basisabschnitt und zwei davon abstehende Schenkelabschnitte aufweist, die jeweils mittels eines Bogenabschnitts mit dem Basisabschnitt verbunden sind, wobei der Trägerteil mit dem Basisabschnitt verbunden ist, und seine Längsränder jeweils mit der Aussenseite der Schenkelabschnitte fluchten.Furthermore, the support part can be connected to a further, rolled iron profile with a bow-shaped cross-sectional shape, which has a base section and two leg sections protruding therefrom, each of which is connected to the base section by means of an arc section, the support part being connected to the base section, and its longitudinal edges in each case align with the outside of the leg sections.

Bei einem weiteren bevorzugten Ausführungsbeispiel ist der Trägerteil und somit der darauf angeordnete Kratzenbeschlag derart bogenförmig aüsgebildet, dass zwischen allen Zahnspitzen des Kardenzylinders und allen Zahnspitzen der Deckelstäbe derselbe Abstand vorherrscht.In a further preferred exemplary embodiment, the carrier part and thus the scraper fitting arranged thereon are embodied in an arcuate manner such that the same distance prevails between all tooth tips of the carding cylinder and all tooth tips of the flat bars.

Aufgrund obiger Ausbildungen kann sich eine erhöhte Spitzenzahl (25% und mehr) ergeben, was eine erhöhte Faserführung und eine bessere Auflösung der Fasern zur Folge haben kann. Der Leerraum bei den Zähnen zwischen benachbarten Deckeln kann nun auf den Abstand dieser benachbarten Deckel reduziert werden. Bekanntlich wirkt sich dieser Leerraum nachteilig auf die Kardierwirkung aus. Weiter können die Luftwirbel zwischen der Trommel und dem sich dazu langsamer bewegenden Deckel reduziert werden. Bei der Sägezahngarnitur kann das Füllungsvermögen stark reduziert werden. Bei bevorzugten Ausführungsbeispielen der Erfindung kann dieser Verlust 0% betragen. Dieses kann insbesondere dann wünschenswert sein, wenn Stapelfasern aus natürlichen und synthetischen Polymeren verarbeitet werden müssen.Due to the above training, there may be an increased number of peaks (25% and more), which may result in increased fiber guidance and better fiber resolution. The space between the teeth between adjacent lids can now be reduced to the distance between these adjacent lids. As is known, this empty space has a negative effect on the carding effect. Furthermore, the air vortices between the drum and the lid, which moves more slowly, can be reduced. With the sawtooth set, the filling capacity can be greatly reduced. In preferred embodiments of the invention, this loss can be 0%. This can be particularly desirable when staple fibers made from natural and synthetic polymers have to be processed.

Nachfolgend wird der Erfindungsgegenstand anhand der Zeichnungen beispielsweise näher erläutert. Es zeigen:

  • Fig. 1 eine Ausführung mit einem flachen Eisenprofil,
  • Fig. 2 eine Ausführung mit einem gekrümmt verlaufenden Eisenprofil,
  • Fig. 3 eine Ausführung mit einem bügelförmigen Träger,
  • Fig. 4 eine Ausführung mit einem bügelförmigen Träger mit einem gekrümmt verlaufenden Basisabschnitt,
  • Fig. 5 eine Ausführung mit einem flachen Eisenprofil, das mit einem bügelförmigen Träger verbunden ist, und
  • Fig. 6 eine Ausführung mit einem gekrümmt verlaufenden Eisenprofil, das mit einem bügelförmigen Träger verbunden ist.
The subject matter of the invention is explained in more detail below with reference to the drawings, for example. Show it:
  • 1 shows an embodiment with a flat iron profile,
  • 2 shows an embodiment with a curved iron profile,
  • 3 shows an embodiment with a bow-shaped carrier,
  • 4 shows an embodiment with a bow-shaped carrier with a curved base section,
  • Fig. 5 shows an embodiment with a flat iron profile, which is connected to a bow-shaped carrier, and
  • Fig. 6 shows an embodiment with a curved iron profile, which is connected to a bow-shaped carrier.

In der Fig. 1 ist ein Trägerteil 20 in Form eines gewalzten, flachen Eisenprofilstückes gezeigt. Auf diesem Trägerteil 20 ist der Sägezahndraht 6 aufgelegt, derart, dass er unmittelbar auf dem Trägerteil 20 aufliegt. Bei beiden äussersten Enden ist der Sägezahndraht 6 mittels einer Schweissung 7, 8 mit den Innenrändern des Trägerteils 20 verschweisst.1 shows a carrier part 20 in the form of a rolled, flat iron profile piece. The sawtooth wire 6 is placed on this carrier part 20 such that it lies directly on the carrier part 20. The sawtooth wire 6 is welded to the inner edges of the carrier part 20 by means of a weld 7, 8 at both extreme ends.

Dabei ist der Sägezahndraht 6 derart bemessen, d.h., er weist eine solche Länge auf, dass seine zwei Stirnflächen 9, 10 mit den Enden des Trägerteils 20 fluchten. Bei der Herstellung wird eine Vielzahl Sägezahndrähte 6 paketförmig auf dem Trägerteil 20 angeordnet. Darauf werden alle Sägezahndrähte 6 mittels jeweils einer Schweissraupe 7, 8 mit den Enden des Trägerteils 20 verbunden. Im Bedarfsfall kann die Aussenseite der Schweissraupen 7, 8 noch abgeschliffen, abgefräst werden, derart, dass die Längsseiten 13, 14 des Trägerteils 20 eine Ebene beschreiben, in welcher jeweils auch die Stirnflächen 9, 10 des Trägerteils 20 sowie die Aussenflächen der Schweissraupen 7, 8 liegen. Der Trägerteil 20 und die damit verbundenen Sägezahndrähte 6, der sogenannte Kratzenbeschlag, kann auf verschiedene Weisen mit den eigentlichen Deckelstäben der Karde verbunden werden. Dazu wird beispielsweise auf die weiter hinten in dieser Beschreibung offenbarten Ausführungsbeispiele hingewiesen.The sawtooth wire 6 is dimensioned in this way, ie it has a length such that its two end faces 9, 10 are aligned with the ends of the carrier part 20. A large number of sawtooth wires 6 are arranged in a packet-like manner on the carrier part 20 during manufacture. All sawtooth wires 6 are then connected to the ends of the carrier part 20 by means of a welding bead 7, 8 in each case. If necessary The outside of the welding beads 7, 8 can also be ground, milled, in such a way that the longitudinal sides 13, 14 of the carrier part 20 describe a plane in which the end faces 9, 10 of the carrier part 20 and the outer surfaces of the welding beads 7, 8 also lie . The carrier part 20 and the sawtooth wires 6 connected to it, the so-called scraper fitting, can be connected to the actual flat bars of the card in various ways. For this, reference is made, for example, to the exemplary embodiments disclosed further on in this description.

In der Fig. 2 ist ein weiteres Ausführungsbeispiel gezeigt. Dieses unterscheidet sich von dem in Fig. 1 gezeigten Ausführungsbeispiel dadurch, dass der Trägerteil 21 bogenförmig verläuft und somit der auf der konkaven Seite des Trägers 20 aufgesetzte Sägezahndraht 6 ebenfalls bogenförmig verläuft. Wieder fluchten die Stirnflächen 9, 10 des Sägezahndrahtes 6 mit den Längsseiten 13, 14 des Trägerteils. Auch hier sind die Sägezahndrähte 6 mittels Schweissraupen 7, 8 mit dem Trägerteil 21 verbunden. Die Deckelstäbe der Karde wirken mit dem Kardenzylinder zusammen, wie dies eingangs erwähnt worden ist. Währenddem die von den Zahnspitzen des Sägedrahtes 6 beschriebenen Ebene der Fig. 1 parallel zu den Tangenten der durch die Zahnspitzen des Kardenzylinders beschriebenen Hüllfläche verläuft, mit der Folge, dass ungleiche Abstände zwischen den Zahnspitzen der Deckelstäbe und den Zahnspitzen des Kardenzylinders vorhanden sind, bewirkt die in der Fig. 2 gezeigte Anordnung, dass alle Zahnspitzen denselben Abstand aufweisen, welches offensichtlich eine verbesserte Kardier- und Kämmwirkung ergibt.A further exemplary embodiment is shown in FIG. 2. This differs from the exemplary embodiment shown in FIG. 1 in that the carrier part 21 extends in an arcuate manner and thus the sawtooth wire 6 placed on the concave side of the carrier 20 also extends in an arcuate manner. Again, the end faces 9, 10 of the sawtooth wire 6 are aligned with the long sides 13, 14 of the carrier part. Here too, the sawtooth wires 6 are connected to the carrier part 21 by means of welding beads 7, 8. The card's flat bars interact with the card cylinder, as mentioned at the beginning. 1 runs parallel to the tangents of the envelope surface described by the tooth tips of the carding cylinder, with the result that there are unequal distances between the tooth tips of the flat bars and the tooth tips of the carding cylinder in the arrangement shown in FIG. 2 that all tooth tips are at the same distance, which obviously results in an improved carding and combing effect.

In der Fig. 3 ist ein Ausführungsbeispiel gezeigt, bei dem der Trägerteil 22 der Basisabschnitt eines bügelförmigen Eisenprofilstückes ist, an welchem Basisabschnitt je ein Bogenabschnitt 2, 3 anschliesst, der in jeweils einem Schenkelabschnitt 4, 5 übergeht. Die Verbindung des aus den soeben genannten Abschnitten gebildeten bügelförmigen Trägers mit dem jeweiligen Deckelstab wird derart durchgeführt, dass die Enden der Schenkelabschnitte 4, 5 in Ausnehmungen im jeweiligen Deckelstab hineingebogen werden, derart, dass der Träger am jeweiligen Deckelstab angeklemmt ist. Dieses ist dem Fachmann wohl bekannt, bildet keinen Teil der vorliegenden Erfindung und wird deshalb auch nicht näher beschrieben.FIG. 3 shows an exemplary embodiment in which the carrier part 22 is the base section of a bow-shaped iron profile piece, to each base section of which an arc section 2, 3 connects, each of which merges into a leg section 4, 5. The connection of the bow-shaped support formed from the sections just mentioned to the respective flat bar is carried out in such a way that the ends of the leg sections 4, 5 are bent into recesses in the respective flat bar, such that the support is clamped on the respective flat bar. This is well known to the person skilled in the art, does not form part of the present invention and is therefore not described in more detail.

Auf dem den Basisabschnitt beschreibenden Trägerteil 22 ist der jeweilige Sägezahndraht 6 aufgelegt, derart, dass er am Trägerteil 22 unmittelbar anliegt. Bei beiden äussersten Enden ist der jeweilige Sägezahndraht 6 mittels einer Schweissung 7, 8 mit dem jeweiligen Bogenabschnitt 2, 3 verbunden. Dazu muss wieder bemerkt werden, dass gruppenweise angeordnete Sägezahndrähte 6 vorhanden sind, die jeweils mit einer Schweissraupe 7, 8 mit den Bogenabschnitten 2, 3 verbunden sind. Das Schweissmaterial der Schweissraupe 7, 8 ist derart angeordnet, dass es aussen mit den Stirnflächen 9, 10 des Sägezahndrahtes 6, bzw. aller Sägezahndrähte 6 und auch mit den Aussenflächen 11, 12 der Schenkelabschnitte 4, 5 fluchtet. Durch diese Anordnung ist wieder ein kleinster Abstand zwischen den Stirnflächen 9, 10 der Sägezahndrähte 6 benachbarter Deckel möglich. Es gibt keine Leerstellen zwischen benachbarten Deckeln, so dass ein Vergleich mit dem Stand der Technik stark erhöhte Kardierwirkung erzielt ist, eine Wirkung, die bei allen Ausführungsbeispielen zutreffend ist.The respective sawtooth wire 6 is placed on the carrier part 22 describing the base section in such a way that it abuts directly on the carrier part 22. At both extreme ends, the respective sawtooth wire 6 is connected to the respective arc section 2, 3 by means of a weld 7, 8. To this end, it must again be noted that sawtooth wires 6 arranged in groups are present, each of which is connected to the arc sections 2, 3 by a welding bead 7, 8. The welding material of the welding bead 7, 8 is arranged such that it is aligned on the outside with the end faces 9, 10 of the sawtooth wire 6, or all the sawtooth wires 6, and also with the outer surfaces 11, 12 of the leg sections 4, 5. With this arrangement, the smallest distance between the end faces 9, 10 of the sawtooth wires 6 of adjacent covers is again possible. There are no empty spaces between adjacent lids, so that a comparison with the prior art, a greatly increased carding effect is achieved, an effect which is true in all exemplary embodiments.

Das in der Fig. 4 gezeigte Ausführungsbeispiel entspricht dem Verlauf des Trägerteiles 23 und des Sägezahndrahtes 6 nach demjenigen der Fig. 2 mit denselben technischen Vorteilen. Der bügelförmige Träger setzt sich aus dem Trägerteil 23 zusammen, der der Basisabschnitt des Bügels ist, an weichem Bogenabschnitte 2 und 3 anschliessen, welche in die Schenkelabschnitte 4 und 5 übergehen. Die Schweissraupen 7, 8, die neben den Stirnflächen 9 und 10 des Sägezahndrahtes 6 angeordnet sind, sind im Vergleich mit dem Ausführungsbeispiel der Fig. 3 weiter eingerückt angeordnet, derart, dass der Sägezahndraht 6 bei beiden Stirnflächen 9, 10 etwas über die Schweissraupen 7, 8 hervorsteht, jedoch im dargestellten Querschnitt gesehen nicht über die Aussenflächen 11, 12 der Schenkelabschnitte 4 und 5 fluchtet.The embodiment shown in FIG. 4 corresponds to the course of the carrier part 23 and the sawtooth wire 6 according to that of FIG. 2 with the same technical advantages. The bow-shaped carrier is composed of the carrier part 23, which is the base section of the bracket, adjoining soft bow sections 2 and 3, which merge into the leg sections 4 and 5. The welding beads 7, 8, which are arranged next to the end faces 9 and 10 of the sawtooth wire 6, are arranged further indented in comparison with the exemplary embodiment in FIG , 8 protrudes, but, seen in the cross section shown, does not align with the outer surfaces 11, 12 of the leg sections 4 and 5.

In der Fig. 5 ist ein weiteres Ausführungsbeispiel dargestellt. Bei diesem Ausführungsbeispiel ist der Sägezahndraht 6 (bzw. die Pakete Sägezahndrähte) auf einem Trägerteil 20 in Form eines flachen Eisenprofils aufgeschweisst. Die Schweissstellen bzw. Schweissraupen 7, 8 befinden sich wieder (siehe Fig. 1) bei den Stirnflächen 9, 10 des jeweiligen Sägezahndrahtes 6 bzw. den Längsseiten 13, 14 des Trägerteils 20. Der Trägerteil 20 ist mittels Schweissungen 15, 16 mit einem Eisenprofilstück mit bügelförmiger Querschnittform verschweisst. Dabei liegt der Trägerteil 20 flach auf dem Basisabschnitt 24 des Bügels auf. Am Basisabschnitt 24 schliessen zwei Bogenabschnitte 2, 3 an, die wie im Ausführungsbeispiel der Fig. 3 in Schenkelabschnitte 4, 5 übergehen. Dabei ist die Anordnung wieder derart gewählt, dass die Aussenflächen 11, 12 der Schenkelabschnitte 4, 5 mit den Stirnflächen 9, 10 des Sägezahndrahtes 6 fluchten. Somit ist eine verstärkte Ausbildung des Kratzenbeschlages, insbesondere des Trägers derselben erzielt.A further exemplary embodiment is shown in FIG. 5. In this embodiment, the sawtooth wire 6 (or the pack of sawtooth wires) is welded onto a carrier part 20 in the form of a flat iron profile. The welding points or welding beads 7, 8 are again (see FIG. 1) at the end faces 9, 10 of the respective sawtooth wire 6 or the longitudinal sides 13, 14 of the carrier part 20. The carrier part 20 is by means of welds 15, 16 with an iron profile piece welded with a bow-shaped cross-sectional shape. The carrier part 20 lies flat on the base section 24 of the bracket. At the base section 24 there are two curved sections 2, 3 which, as in the exemplary embodiment in FIG. 3, merge into leg sections 4, 5. The arrangement is again chosen such that the outer surfaces 11, 12 of the leg sections 4, 5 are aligned with the end surfaces 9, 10 of the sawtooth wire 6. An increased formation of the scraper fitting, in particular of the carrier thereof, is thus achieved.

Die Fig. 6 zeigt ein Ausführungsbeispiel mit bogenförmig verlaufendem Träger 21 in Form eines gewalzten Eisenprofils. Die jeweiligen Sägezahndrähte 6 sind mittels Schweissraupen 7, 8 beim Bereich ihrer Stirnflächen 9, 10 mit dem Trägerteil 21 verschweisst. Diese Anordnung entspricht der in der Fig. 2 gezeigten. Der Trägerteil 21 ist mittels Schweissungen 17, 18 mit dem Basisabschnitt 25 eines Eisenprofilstückes mit bügelförmiger Querschnittform verschweisst. Am Basisabschnitt 25 schliessen wieder die Bogenabschnitte 2, 3 an, welche in die Schenkelabschnitte 4, 5 übergehen. Es ist wieder ersichtlich, dass die Längsseiten 13, 14 des Trägerteiles 21 mit den Aussenflächen 11, 12 der Schenkelabschnitte 4, 5 fluchten.Fig. 6 shows an embodiment with an arcuate support 21 in the form of a rolled iron profile. The respective sawtooth wires 6 are welded to the carrier part 21 by means of welding beads 7, 8 in the region of their end faces 9, 10. This arrangement corresponds to that shown in FIG. 2. The carrier part 21 is welded to the base section 25 of an iron profile piece with a bow-shaped cross-sectional shape by means of welds 17, 18. At the base section 25, the arc sections 2, 3 connect again, which merge into the leg sections 4, 5. It can be seen again that the long sides 13, 14 of the carrier part 21 are aligned with the outer surfaces 11, 12 of the leg sections 4, 5.

Aus allen Ausführungsbeispiel geht hervor, dass zwischen den einzelnen Deckeln der Karde kein Abstand zwischen den Sägezahndrähten 6 mehr vorhanden ist, also keine Leerstellen vorhanden sind. Auch ist zu bemerken, dass die gezeigten Ausführungsbeispiele äusserst einfach und zeitsparend herstellbar sind, und somit die Kratzenbeschläge schneller und kostengünstiger als bisher hergestellt werden können.It can be seen from all the exemplary embodiments that there is no longer any distance between the sawtooth wires 6 between the individual lids of the card, that is to say there are no empty spaces. It should also be noted that the execution shown Examples are extremely simple and time-saving to manufacture, and the scraper fittings can be manufactured faster and more cost-effectively than before.
