Description
Die Erfindung betrifft einen Deckelstab für eine Karde mit einem Grundkörper, einer Garnitur und wenigstens einem Befestigungsmittel für die Garnitur.The invention relates to a flat bar for a carding machine with a base body, a clothing and at least one fastening means for the clothing.
Für die Befestigung von einer Garnitur an einem Deckelstab für eine Karde werden seit Jahrzehnten Blechstreifen verwendet, die plastisch verformt werden, um die Garnitur am Deckelstab zu halten. Derartige plastisch verformte Blechstreifen als Befestigungsmittel für die Garnitur sind beispielsweise in den Figuren der
Zum Wechseln einer verschlissenen Garnitur muss der Blechstreifen zerstört werden. Zum Aufziehen einer neuen Garnitur sind neue Blechstreifen erforderlich. Für das Umbiegen der Blechstreifen und das Fixieren der Garnitur sind spezielle Servicemaschinen notwendig.To change a worn set the sheet metal strip must be destroyed. To attach a new set new sheet metal strips are required. For the bending of the metal strips and the fixing of the set special service machines are necessary.
Der Erfindung liegt die Aufgabe zugrunde, einen Deckelstab für eine Karde zu schaffen, bei dem ein Wechseln der Garnitur mit weniger Aufwand möglich ist.The invention has for its object to provide a flat bar for a card, in which a change of the set with less effort is possible.
Die Aufgabe wird dadurch gelöst, dass das Befestigungsmittel durch eine Klemmschiene gebildet wird. Die Klemmschiene ist vorzugsweise zerstörungsfrei lösbar.The object is achieved in that the fastening means is formed by a clamping rail. The clamping rail is preferably non-destructive solvable.
Durch eine leicht lösbare Klemmschiene ist die Garnitur am Deckelstab ohne Verwendung spezieller Servicemaschinen wechselbar. Außerdem kann die Klemmschiene zur Befestigung der neuen Garnitur wieder verwendet werden.By an easily detachable clamping rail, the clothing on the flat bar without the use of special service machines is changeable. In addition, the clamping rail can be used to attach the new set again.
Bevorzugt sind der Klemmschiene Mittel zum Erzeugen einer Klemmkraft zugeordnet. Die Mittel zum Erzeugen einer Klemmkraft sind bevorzugt durch wenigstens eine Schraube oder durch wenigstens einen Hebel gebildet. Die Mittel zum Erzeugen der Klemmkraft können dabei sowohl an der Klemmschiene selbst, als auch am Grundkörper des Deckelstabs angebracht sein. Die Mittel zum Erzeugen der Klemmkraft können auch als separates Bauteil ausgestaltet sein, das mit Grundkörper und Klemmschiene zusammenwirkt.Preferably, the clamping rail are assigned means for generating a clamping force. The means for generating a clamping force are preferably by at least one screw or by formed at least one lever. The means for generating the clamping force can be attached both to the clamping rail itself, as well as on the main body of the flat bar. The means for generating the clamping force can also be designed as a separate component, which cooperates with the base body and clamping rail.
