Description

Die Erfindung betrifft eine Karde gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a card according to the preamble of claim 1.

Eine derartige Karde dient zur Parallelisierung von Fasern, insbesondere Baumwollfasern. Die Fasern werden in Bündeln in Längsrichtung ausgerichtet auf einem Tambour geführt und liegen dabei auf dessen Mantelfläche auf. Der Tambour weist die Form einer zylindrischen Walze auf, die horizontal liegend gelagert ist.Such a card serves to parallelize fibers, in particular Cotton fibers. The fibers are aligned in bundles in the longitudinal direction performed on a drum and lie on its outer surface. The Drum has the shape of a cylindrical roller, lying horizontally is stored.

Die in Umfangsrichtung auf dem Tambour geführten Fasern stehen in Eingriff mit Garnituren, die auf einer über ein Walzensystem geführten Kardierschiene aufgebracht sind. Die einzelnen Garnituren bestehen aus flexiblen streifenförmigen Stofflagen, an deren Oberseite Kammstrukturen in Form von metallischen Nadelkämmen ausgebildet sind.The fibers guided in the circumferential direction on the drum are in engagement with trimmings on a carding rail guided over a roller system are upset. The individual sets consist of flexible strip-shaped Fabric layers with comb structures in the form of metallic on the top Needle combs are formed.

Die Garnituren verlaufen in Längsrichtung des Tambours dicht oberhalb dessen Oberfläche, so dass durch die Kammstrukturen die Fasern gekämmt und in Längsrichtung ausgerichtet werden.The sets run in the longitudinal direction of the drum just above it Surface, so that the fibers are combed and in by the comb structures Longitudinal direction to be aligned.

Dabei ist jede Garnitur an einem Deckelstab befestigt, wobei die Abmessungen der Deckelstäbe an die Abmessungen der Garnituren angepasst sind. Die Deckelstäbe mit den Garnituren werden an der Kardierschiene geführt.Each set is attached to a flat bar, the dimensions the flat bars are adapted to the dimensions of the sets. The flat bars with the sets are guided on the carding rail.

Bei bekannten Karden liegen die Garnituren an den Oberseiten der Deckelstäbe auf. Die Deckelstäbe sind dabei an den oberen Enden verbreitert und weisen die Form von Profilen mit rechteckigen Querschnitten auf, wobei die Garnituren auf der gesamten oberen Stimseite dieser Profile aufliegen. Zur Befestigung werden an die Seitenwände Blechteile oder dergleichen angelegt, die über den oberen Rand der Profile mit den Garnituren und über den unteren Rand der Profile etwas hervorstehen. Durch Umbördeln werden die überstehenden Enden der Blechteile gebogen, so dass diese an den Ober- und Unterseiten der Profile anliegen und so die jeweilige Garnitur an einem Profil fixieren.In the case of known cards, the clothing is on the upper sides of the flat bars on. The flat bars are widened at the upper ends and have the shape of profiles with rectangular cross-sections, with the trimmings rest on the entire upper face of these profiles. For fixing sheet metal parts or the like are created on the side walls, the over the upper edge of the profiles with the trimmings and over the lower edge of the Profiles stick out a little. The protruding ends are crimped of the sheet metal parts bent so that these on the top and bottom sides of the profiles fit and thus fix the respective set on a profile.

Die einzelnen Garnituren sind relativ verschleißanfällig, so dass diese in vorgegebenen Zeitintervallen ausgetauscht werden müssen. Hierzu werden die Garnituren mit den fest mit diesen verbundenen Deckelstäben von der Kardierschiene abmontiert. Dann werden diese in mechanischen Werkstätten oder Servicestationen mechanisch bearbeitet, um die durch Umbördelung an den Deckelstäben fixierten Garnituren zu lösen. Anschließend werden neue Garnituren auf die Deckelstäbe aufgebracht und durch Bördeln von seitlich angebrachten neuen Blechteilen fixiert.The individual sets are relatively susceptible to wear, so that they are given in predetermined Time intervals have to be exchanged. For this, the Sets with the flat bars firmly connected to them from the carding rail dismounted. Then they are in mechanical workshops or service stations machined to the by flanging on the flat bars to loosen fixed sets. Then new trimmings applied to the flat bars and by crimping from the side fixed new sheet metal parts.

Nachteilig hierbei ist zum einen, dass der Montageaufwand zum Auswechseln der Garnituren sehr hoch ist. Insbesondere ist dabei nachteilig, dass der Wechsel der Garnituren entsprechende mechanische Werkzeuge erfordert, so dass der Wechsel nicht vor Ort an der Karde durchgeführt werden kann, sondern in mechanischen Werkstätten oder Servicestationen durchgeführt werden muss. Daher müssen für den Wechsel der Garnituren nicht nur beträchtliche Montagezeiten sondern auch erhebliche Transportzeiten und Transportkosten in Kauf genommen werden.On the one hand, it is disadvantageous that the assembly effort for replacement the sets are very high. A particular disadvantage is that the change the sets require appropriate mechanical tools, so that the change can not be carried out on site at the card, but in mechanical workshops or service stations must be carried out. Therefore, changing the sets does not only require considerable assembly times but also significant transportation times and transportation costs in purchase be taken.
