Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Bearbeiten von Textilfasern nach dem Oberbegriff des Patentanspruchs 1., ein zum Herstellen einer derartigen Vorrichtung geeignetes Kardierelement sowie zum Herstellen dieser Kardierelemente einsetzbare Sägezahndrahtabschnitte.The invention relates to a device for processing textile fibers according to the preamble of patent claim 1, a suitable for producing such a device carding and usable for producing these carding sawtooth wire sections.
Vorrichtungen der eingangs beschriebenen Art werden beispielsweise in Form von Vorauflösesektionen in zum Herstellen eines Faservlieses mit einheitlich ausgerichteten Fasern aus einem Fasermaterial mit uneinheitlicher Faserausrichtung geeigneten Karden oder Krempeln eingesetzt. Nachstehend wird die Funktion derartiger Karden oder Krempeln anhand der Figuren 3 bis 5 erläutert. Dabei zeigt die Fig. 3 eine schematische Darstellung des Grundaufbaus einer Karde bzw. Krempel. Danach weist die Karde einen insgesamt mit 12 bezeichneten Zuführkanal zum Zuführen des aus ungeordneten Fasern bestehenden Fasermaterials zu einer Vorauflösesektion 20 auf. Mit dieser Vorauflösesektion 20 wird das Fasermaterial dem Tambour 30 der Karde vorgelegt. Bei diesem Tambour handelt es sich um eine Walze, die auf ihrer Mantelfläche mit einer Häckchen- und/oder Sägezahn-Ganzstahlgarnitur versehen ist. Beim Betrieb der Karde wird der Tambour um seine Walzenachse gedreht. Dabei werden die von der Vorauflösesektion vorgelegten Fasern von der Garnitur erfaßt und in Drehrichtung der Walze ausgerichtet. Zur Verbesserung der Faserausrichtung werden in Umfangsrichtung über die Mantelfläche des Tambours verteilt angeordnete Deckelstäbe 32 eingesetzt. Diese Deckelstäbe weisen eine in einer Arbeiststellung der Mantelfläche des Tambours zugewandte Arbeitsfläche auf, die ebenfalls in Form einer Häckchen- und/oder Sägezahn-Ganzstahlgarnitur gebildet sein kann. Dabei können die Deckelstäbe entweder feststehend angeordnet sein oder in einer der Drehrichtung des Tambours entgegengesetzten Richtung bewegt werden. Schließlich wird das Faservlies mit einer Abnehmerwalze 14 abgenommen und einer weiteren Verarbeitung zugeführt. Bei der anhand der Fig. 3 beschriebenen Karde dient die Vorauflösesektion einerseits einer kontrollierten Zuführung des ungeordneten Fasermaterials zum Tambour und andererseits einer gleichmäßigen Verteilung des Fasermaterials über die gesamte axiale Länge des Tambours.Devices of the type described in the introduction are used, for example, in the form of pre-dissolving sections in cards or carding machines suitable for producing a non-woven fabric with uniformly aligned fibers of a fiber material with non-uniform fiber orientation. Hereinafter, the function of such cards or carding will be explained with reference to Figures 3 to 5. FIG. 3 shows a schematic representation of the basic structure of a carding machine or carding machine. Thereafter, the carding machine has a supply channel, generally designated 12, for supplying the fiber material consisting of disordered fibers to a
Fig. 4 zeigt eine Detaildarstellung dieser Vorauflösesektion 20. Bei der in dieser Figur dargestellten Vorauflösesektion 20 sind insgesamt 3 Vorreißerwalzen 22, 24 und 26 vorgesehen, die in den durch die Pfeile A bezeichneten Richtungen um die Walzenachsen 22a 24a und 26a drehbar sind. Jede der Vorreißerwalzen 22, 24 und 26 weist eine kreiszylindermantelförmige Bearbeitungsfläche auf, welche mit einer Häckchen- und/oder Sägezahn-Ganzstahlgarnitur ausgestattet sein kann. Insbesondere beim Einsatz von Hochleistungskarden und Hochleistungskrempeln zur Kurz- und Langstapelverarbeitung von Textilfasern aus natürlichen oder synthetischen Polymeren ist es üblich, den einzelnen Vorreißerwalzen 22, 24 und 26 auch noch sogenannte Festkardierelemente 23, 25 und 27 zuzuordnen, um so eine bessere Faserverteilung zu erzielen. Die Anordnung dieser Festkardierelemente wird in Fig. 5 beispielhaft für das Festkardierelement 27 erläutert. Dabei zeigt Fig. 5a einen Schnitt längs einer senkrecht zur Walzenachse 26a verlaufenden Schnittebene und Fig. 5b eine Draufsicht auf das Festkardierelement 27. Aus Fig. 5a geht hervor, daß das Festkardierelement 27 im wesentlichen aus einem Trägerelement 27a und auf diesem Trägerelement 27a festgelegten Sägezahndrahtabschnitten 27b besteht. Dabei verlaufen diese Sägezahndrahtabschnitte 27b etwa tangential zu der ebenfalls mit einer Sägezahn-Ganzstahlgarnitur ausgestatteten Mantelfläche der Vorreißerwalze 26. Gemäß Fig. 5b weist das Festkardierelement eine Vielzahl von nebeneinander angeordneten und auf dem Trägerelement 27a festgelegten Sägezahndrahtabschnitten auf. Bei herkömmlichen Karden weisen die Festkardierelemente eine Breite von etwa 32 bis 52 mm auf und sind aus Gußeisen, Stahl, Aluminium, Magnesium oder synthetischem Material hergestellt, wobei zwischen den Spitzen der Sägezahndrahtstreifen 27b und denjenigen der Garnitur der Vorreißerwalze ein Mindestabstand in der Größenordnung von 0,1 bis 1,0 mm eingehalten ist. In der Zone der größten Annäherung der Sägezahndrahtstreifen 27b an die Garnitur der Vorreißerwalze 26 findet eine Faserverstreichung statt, die eine erste Ausrichtung des Fasermaterials und eine gleichmäßige Verteilung dieses Fasermaterials bewirkt. Die Breite der Zone, längs der die Faserverstreichung stattfindet, entspricht etwa der durchschnittlichen Faserlänge des vorgelegten Fasermaterials.Fig. 4 shows a detailed illustration of this pre-resolving
Beim Einsatz der anhand der Fig. 3 bis 5 erläuterten Karden hat es sich gezeigt, daß in dem von der Abnehmerwalze 40 abgenommenen Faservlies insbesondere bei hohen Arbeitsgeschwindigkeiten eine ungleichmäßige Faserverteilung auftreten kann.When using the cards explained with reference to FIGS. 3 to 5, it has been shown that uneven fiber distribution can occur in the nonwoven fabric removed by the

Dabei zeigt Fig.1a eine Schnittdarstellung in einer senkrecht zur Achse einer Vorreißerwalze verlaufenden Schnittebene und Fig. 1b eine Draufsicht auf das in Fig. 1a dargestellte Kardierelement. Gemäß Fig. 1a umfaßt die Vorrichtung eine Vorreißerwalze 110, von der nur ein Ausschnitt der kreiszylindermantelförmigen Bearbeitungsfläche dargestellt ist und ein Kardierelement. Das Kardierelement umfaßt ein Trägerelement 120 und eine Vielzahl von nebeneinander angeordneten Sägezahndrahtabschnitt 130. Dabei ist die Anordnung der Sägezahndrahtabschnitte besonders deutlich in der Draufsicht nach Fig. 1b erkennbar. Die Sägezahndrahtabschnitte 130 weisen zwei einen stumpfen Winkel miteinander einschließende Segmente 132 und 134 auf, welche über ein Verbindungssegment 136 miteinander verbunden sind. Das Verbindungssegment 136 weist einen dem stumpfen Winkel entsprechenden Knick auf und ist ohne Sägezähne ausgeführt, um so die Knickbildung zu erleichtern.1 shows a
