Description

Die Erfindung betrifft ein Käfigaggregat für ein Streckwerk einer Textilmaschine mit einem Käfig zum Führen zweier einen Druckwalzenzwilling eines Streckwerks umschlingenden Führungsriemchen, mit einer austauschbaren Käfigstütze und mit einem austauschbaren Führungselement zum Führen eines Faserverbandes. Die Erfindung betrifft ferner eine Käfigstütze und ein Führungselement für ein Käfigaggregat.The invention relates to a cage assembly for a drafting system of a textile machine with a cage for guiding two of a pressure rolling twin of a drafting device looping guide straps, with an exchangeable cage support and with an exchangeable guide element for guiding a fiber structure. The invention further relates to a cage support and a guide element for a cage assembly.

Ein Käfigaggregat dieser Art ist aus der DE 102 52 631 A1 bekannt. Ein Führungselement in Form eines Rundstabes ist mit Halteelementen direkt am Käfig befestigt. Die Käfigstütze, die in der DE 102 52 631 A1 als "Distanzstück" bezeichnet wird, ist getrennt vom Führungselement am Käfig angebracht.A cage unit of this kind is from the DE 102 52 631 A1 known. A guide element in the form of a round rod is fastened with retaining elements directly on the cage. The cage support, which in the DE 102 52 631 A1 is referred to as a "spacer" is mounted separately from the guide element on the cage.

Seitens der Besitzer der Textilmaschine besteht oftmals der Wunsch, ein Führungselement an älteren, bereits vorhandenen Käfigaggregaten nachzurüsten. Da die aus der DE 102 52 631 A1 bekannten Führungselemente unmittelbar am Käfig befestigt werden, kommt es oftmals vor, dass die vorhandenen Käfige eine solche Befestigung der Führungselemente nicht zulassen. Es ist dann erforderlich, den gesamten Käfig auszutauschen. Ein Austausch des Käfigs ist für den Besitzer der Textilmaschine ein höherer Umbauaufwand, der zudem wesentlich kostspieliger ist, als wenn nur Führungselemente zugekauft werden müssten.On the part of the owner of the textile machine, there is often the desire to retrofit a guide element on older, already existing cage assemblies. Since the from the DE 102 52 631 A1 known guide elements are attached directly to the cage, it often happens that the existing cages do not allow such attachment of the guide elements. It is then necessary to replace the entire cage. An exchange of the cage is for the owner of the textile machine, a higher conversion effort, which is also much more expensive than if only guide elements would have to be purchased.

Der Erfindung liegt die Aufgabe zugrunde, Käfigaggregat, Führungselement und Käfigstütze zu verbessern.The invention has for its object to improve cage unit, guide element and cage support.

Die Aufgabe wird dadurch gelöst, dass die Käfigstütze und das Führungselement lösbar aneinander befestigt und am Käfig angebracht sind.The object is achieved in that the cage support and the guide element are releasably secured together and attached to the cage.

Dadurch dass die Käfigstütze und das Führungselement aneinander befestigt sind, ist für die gemeinsame Anbringung dieser beiden Teile nur eine Befestigung am Käfig erforderlich. Käfigstütze und Führungselement können so ausgelegt werden, dass die eine, am Käfig vorhandene Befestigungsmöglichkeit ausreichend ist. Ein Austausch des Käfigs bei einer Nachrüstung eines Führungselementes zum Führen des Faserverbandes in der Hauptverzugszone des Streckwerks ist nicht mehr notwendig. An dem vorhandenen Käfig kann wahlweise nur eine herkömmliche Käfigstütze oder aber eine Käfigstütze mit Führungselement angebracht werden. Auch ein vorhandenes Käfigaggregat kann dadurch mit wenig Umbauaufwand und sehr kostengünstig an unterschiedliche Anforderungen angepasst werden.The fact that the cage support and the guide element are fastened to each other, only one attachment to the cage is required for the joint attachment of these two parts. Cage support and guide element can be designed so that the one, on the cage existing mounting option is sufficient. An exchange of the cage when retrofitting a guide element for guiding the fiber structure in the main drafting zone of the drafting system is no longer necessary. Optionally, only a conventional cage support or a cage support with guide element can be attached to the existing cage. An existing cage unit can be adapted to different requirements with little conversion and very cost.

Aus der nicht gattungsgemäßen CN 201045153 Y ist ein Käfigaggregat bekannt, bei dem ein Führungselement unlösbar mit einer Käfigstütze verbunden ist. Das Führungselement ist direkt an die Käfigstütze angespritzt. Käfigstütze und Führungselement bilden ein integriertes Bauteil und sind dadurch nicht mehr separat austauschbar. Um alle notwendigen Variationen von erforderlichen Käfigstützen und von unterschiedlichen Positionen von Führungselementen abzudecken, ist eine sehr große Anzahl an unterschiedlichen Bauteilen notwendig. Zur Erreichung des optimalen Verzugsergebnisses ist jedoch oftmals erforderlich, die Maulweite unabhängig von der Position des Führungselementes einzustellen. Um bei einer Ausführung gemäß der CN 201045153 Y sämtliche Kombinationen von Maulweiten und Positionen des Führungselementes abzudecken, ist eine sehr große Anzahl an unterschiedlichen Teilen erforderlich, die alle von dem Besitzer der Textilmaschine vorrätig gehalten werden müssen. Auch ist bei einer großen Anzahl unterschiedlicher Teile, die sich nur geringfügig unterscheiden, eine hohe Verwechslungsgefahr gegeben, so dass die Gefahr besteht, dass nicht alle Käfigaggregate einer Maschine gleich eingestellt sind. Die Qualität der erzeugten Garne kann dadurch variieren.From the non-generic CN 201045153 Y a cage assembly is known in which a guide element is permanently connected to a cage support. The guide element is molded directly onto the cage support. Cage support and guide element form an integrated component and are therefore no longer separately exchangeable. To cover all necessary variations of required cage supports and different positions of guide elements, a very large number of different components is necessary. However, in order to achieve the optimum draft result, it is often necessary to set the jaw width independently of the position of the guide element. In an embodiment according to the CN 201045153 Y To cover all combinations of jaw widths and positions of the guide element, a very large number of different parts is required, all of which must be kept in stock by the owner of the textile machine. Also, with a large number of different parts, which differ only slightly, there is a high risk of confusion, so that there is a risk that not all cage units of a machine are set the same. The quality of the yarns produced can vary as a result.

Bei dem erfindungsgemäßen Käfigaggregat sind zwei Varianten denkbar, wie Käfigstütze und Führungselement am Käfig angeordnet werden können. Bei einer ersten Variante ist die Käfigstütze direkt am Käfig befestigt und das Führungselement ist an der Käfigstütze befestigt. Bei der zweiten Variante ist das Führungselement direkt am Käfig befestigt und die Käfigstütze ist dann an dem Führungselement befestigt. Beide Varianten erlaubten die Verwendung des vorhandenen Käfigs mit seinen Befestigungsmitteln, die ursprünglich für eine Käfigstütze ohne Führungselement ausgelegt waren. Die vorhandenen Käfige können dadurch problemlos weiterverwendet werden. Dies ist sowohl ein Vorteil für die Besitzer von Textilmaschinen als auch für Hersteller von Käfigaggregaten. Der Hersteller von Käfigaggregaten kann seine bisherigen Werkzeuge und Vorrichtungen für die Herstellung der Käfige ohne Änderung weiterverwenden. Lediglich die vorhandene Käfigstütze muss ersetzt werden. Eine Käfigstütze ist jedoch ein einfaches Bauteil, das wenig kostet und dessen Austausch auch keinen großen Umbauaufwand bedeutet. Bei einer Anpassung der Maschine an ein anderes Fasermaterial wird oftmals die Käfigstütze ohnehin getauscht.In the cage assembly according to the invention, two variants are conceivable, such as cage support and guide element can be arranged on the cage. In a first variant, the cage support is attached directly to the cage and the guide element is attached to the cage support. In the second variant, the guide element is attached directly to the cage and the cage support is then attached to the guide element. Both variants allowed the use of the existing cage with its fasteners, which were originally designed for a cage support without guide element. The existing cages can be used easily. This is both an advantage for the owners of textile machinery as well as for manufacturers of cage assemblies. The manufacturer of cage units can continue to use his previous tools and devices for the production of cages without modification. Only the existing cage support must be replaced. However, a cage support is a simple component that costs little and whose replacement also means no major conversion effort. When adapting the machine to another fiber material, the cage support is often replaced anyway.

Durch die getrennte Austauschbarkeit von Käfigstütze und Führungselement wird für jedes Käfigaggregat nur jeweils ein Satz Käfigstützen zur Einstellung der unterschiedlichen Maulweiten und ein Satz von Führungselementen mit den unterschiedlichen Positionen der Führungsflächen benötigt. Je nach Anforderung lässt sich dann die benötigte Kombination von Käfigstütze und Führungselement am Käfig anbringen. Die Teilevielfalt ist dadurch gering gehalten. Auch die Gefahr, dass eine Käfigstütze oder ein Führungselement mit den falschen Abmessungen versehentlich eingebaut wird, ist dadurch sehr gering. Die Identifikation der Varianten wird bevorzugt durch farbliche Kennzeichnung sichergestellt.Due to the separate interchangeability of cage support and guide element only one set of cage supports for adjusting the different jaw widths and a set of guide elements with the different positions of the guide surfaces is required for each cage unit. Depending on requirements, the required combination of cage support and guide element can then be attached to the cage. The variety of parts is kept low. The risk that a cage support or a guide element with the wrong dimensions is accidentally installed, is therefore very low. The identification of the variants is preferably ensured by color coding.

Da die Führungselemente und die Käfigstützen selbstständig handelbare Bauteile sind, wird für sie unabhängig vom Käfigaggregat Patentschutz beansprucht. Ein erfindungsgemäßes Führungselement weist Befestigungsmittel zum Verbinden mit einer Käfigstütze auf. Eine erfindungsgemäße Käfigstütze weist Befestigungsmittel zum Verbinden mit einem Führungselement für den Faserverband auf. Hierdurch lässt sich erreichen, dass die Käfigstütze und das Führungselement aneinander befestigbar sind. Das Führungselement oder die Käfigstütze weist Befestigungsmittel zum Verbinden mit einem Käfig auf. Die Befestigungsmittel zum Verbinden mit dem Käfig sind an die am Käfig vorhandenen Befestigungsmittel angepasst. Vorteilhafterweise sind alle Befestigungsmittel als Schnappverbindungen ausgestaltet. Eine Schnappverbindung wird bevorzugt durch wenigstens einen zapfenartigen Vorsprung an dem einen Teil und eine zugehörige Aussparung an dem anderen Teil gebildet. Die einzelnen Teile lassen sich dadurch sehr leicht aneinander klipsen und sind auch problemlos wieder voneinander lösbar.Since the guide elements and the cage supports are independently tradable components, patent protection is claimed for them independently of the cage assembly. An inventive guide element has fastening means for connecting to a cage support. A cage support according to the invention has fastening means for connection to a guide element for the fiber structure. This makes it possible to achieve that the cage support and the guide element are fastened to each other. The guide element or the cage support has fastening means for connecting to a cage. The attachment means for connecting to the cage are adapted to the attachment means present on the cage. Advantageously, all fastening means are designed as snap connections. A snap connection is preferably formed by at least one pin-like projection on one part and an associated recess on the other part. The individual parts can be easily clipped to each other and are also easily problem solving again.

In vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass die Käfigstütze und das Führungselement jeweils wenigstens eine Abstützfläche zur direkten Anlage am Käfig aufweisen. Eine Abstützfläche, die direkt am Käfig anliegt, gewährleistet eine sehr präzise Positionierung von Käfigstütze und Führungselement unmittelbar durch den Käfig. Obwohl Käfigstütze und Führungselement aneinander befestigt sind kommt es nicht zu einer vergrößerten Lageungenauigkeit eines der beiden Teile durch eine Addition von Fertigungstoleranzen. Käfigstütze und Führungselement werden weitgehend unabhängig voneinander durch die Abstützfläche direkt vom Käfig positioniert. Es wird in einer sehr vorteilhaften Weise die getrennte Verstellbarkeit von Käfigstütze und Führungselement mit einer sehr guten Genauigkeit und einer einfachen Nachrüstbarkeit an vorhandenen Käfigen ineinander vereint.In an advantageous embodiment of the invention, it is provided that the cage support and the guide element each have at least one support surface for direct contact with the cage. A support surface, which rests directly on the cage, ensures a very precise positioning of the cage support and guide element directly through the cage. Although cage support and guide element are attached to each other, there is no increased inaccuracy of position of one of the two parts by an addition of manufacturing tolerances. Cage support and guide element are largely independent of each other through the Support surface positioned directly from the cage. It is combined in a very advantageous manner, the separate adjustability of cage support and guide element with a very good accuracy and easy retrofitting to existing cages each other.

In weiterer vorteilhafter Ausgestaltung ist vorgesehen, dass die Führungsfläche für den Faserverband am Führungselement durch eine Stange, vorzugsweise eine zylindrische Stange, gebildet wird. Bevorzugt weist das Führungselement einen Halter auf, an dem Befestigungsmittel angeordnet sind. Der Halter kann direkt an die die Führungsfläche enthaltende Stange angespritzt sein. Bei der Käfigstütze ist es vorteilhaft, dass eine Aussparung für einen Bereich des Führungselementes, der eine Abstützfläche aufweist, in der Käfigstütze vorgesehen ist.In a further advantageous embodiment, it is provided that the guide surface for the fiber structure on the guide element by a rod, preferably a cylindrical rod is formed. Preferably, the guide element has a holder, on which fastening means are arranged. The holder can be molded directly onto the rod containing the guide surface. In the cage support, it is advantageous that a recess for a region of the guide element, which has a support surface, is provided in the cage support.

Der Unterwalze 12 ist ein Führungsriemchen 16 zugeordnet, das zusätzlich durch eine Unterriemchenführung 17 geführt wird. Die Unterwalze 12 und die Unterriemchenführung 17 erstrecken sich über mehrere benachbarte Streckwerke 10, 10'. Dem Walzenpaar 12, 5 ist ein Walzenpaar 18, 19 nachgeordnet, welches mit höherer Umfangsgeschwindigkeit antreibbar ist. Zwischen dem Walzenpaar 12, 5 und dem Walzenpaar 18, 19 wird der Faserverband 15 aus Stapelfasern verzogen, so dass im Anschluss an das Walzenpaar 18, 19 ein dünnerer Faserverband vorliegt. Das Streckwerk kann weitere, nicht dargestellte Walzenpaare enthalten.In FIG. 2 schematically a drafting system 10 is shown. The cage unit 1 with its top roller 5, the cage 3 and the guide belt 4 is associated with a bottom roller 12. A fiber structure 15 to be distorted passes through the pair of rollers 12, 5 in the transport direction A. The lower roller 12 is assigned a guide belt 16, which is additionally guided by a lower apron guide 17. The lower roller 12 and the lower apron guide 17 extend over a plurality of adjacent drafting systems 10, 10 '. The pair of rollers 12, 5 is a pair of rollers 18, 19 arranged downstream, which is driven at a higher peripheral speed. Between the pair of rollers 12, 5 and the roller pair 18, 19 of the fiber structure 15 is warped from staple fibers, so that there is a thinner fiber structure after the pair of rollers 18, 19. The drafting system may contain further roller pairs, not shown.

Während des Verzuges in der Verzugszone 20 zwischen den Walzenpaaren wird der Faserverband 15 durch die Führungsriemchen 16, 4 geführt. Damit der Faserverband 15 in der Verzugszone 20 nicht zu stark durch die Führungsriemchen 16 und 4 zusammengedrückt wird, ist vorgesehen, dass die Umlenkkante 8 für das Oberriemchen 4 einen definierten Abstand von der Umlenkkante 21 der Unterriemchenführung 17 aufweist. Dieser Abstand zwischen den Umlenkkanten 21 und 8 wird als Maulweite bezeichnet. Durch den Einsatz von unterschiedlichen Käfigstützen 13 kann die Maulweite verändert werden. Zur Verbesserung der Führung des Faserverbandes 15 in der Verzugszone 20 ist stromabwärts der Führungsriemchen 16 und 4 eine Führungsfläche 22 des Führungselementes 14 angeordnet. Die Führungsfläche 22 ist konvex. Die Führungsfläche 22 wird bevorzugt durch den Außenumfang einer Stange gebildet, die sich über das gesamte Käfigaggregat 1 erstreckt. Die Führungsfläche 22 ist bevorzugt so positioniert, dass der Faserverband 15 leicht aus einer gedachten Verbindungslinie ausgelenkt wird, die durch die kürzeste Verbindung zwischen dem Austritt der Führungsriemchen 16, 4 und der Klemmlinie des Walzenpaares 18, 19 gebildet wird. Die Führungskraft, die das Führungselement 14 auf den Faserverband 15 in der Verzugszone 20 ausübt, hängt im Wesentlichen von der Größe der Auslenkung des Faserverbandes 15 aus der gedachten kürzesten Verbindungslinie ab. Es ist deshalb vorgesehen, dass die Position der Führungsfläche 22 durch den Einsatz von unterschiedlichen Führungselementen 14 variiert werden kann.During the delay in the drafting zone 20 between the roller pairs, the fiber structure 15 is guided by the guide straps 16, 4. So that the fiber structure 15 is not compressed too strongly in the drafting zone 20 by the guide straps 16 and 4, it is provided that the deflection edge 8 for the top apron 4 has a defined distance from the deflection edge 21 of the bottom apron guide 17. This distance between the deflecting edges 21 and 8 is referred to as jaw width. Through the use of different cage supports 13, the mouth width can be changed. To improve the guidance of the fiber structure 15 in the draft zone 20, a guide surface 22 of the guide element 14 is arranged downstream of the guide aprons 16 and 4. The guide surface 22 is convex. The guide surface 22 is preferably formed by the outer periphery of a rod which extends over the entire cage unit 1. The guide surface 22 is preferably positioned so that the fiber structure 15 is easily deflected from an imaginary connecting line, which passes through the shortest connection between the exit of the Führungsriemchen 16, 4 and the nip line of the pair of rollers 18, 19 is formed. The manager, who exerts the guide member 14 on the fiber structure 15 in the draft zone 20, depends essentially on the size of the deflection of the fiber structure 15 from the imaginary shortest connecting line. It is therefore provided that the position of the guide surface 22 can be varied by the use of different guide elements 14.

Mit Hilfe der Figuren 3 bis 5 wird die erfindungsgemäße Ausgestaltung der Käfigstütze 13 und des Führungselementes 14 näher erläutert. Die Käfigstütze 13 weist eine nutförmige Aufnahme 23 für den Käfig 3 auf. Die Käfigstütze 13 wird mit der Aufnahme 23 auf eine Vorderkante 35 des Käfigs 3 geschoben. Die Aufnahme 23 enthält Abstützflächen 24, die eine Positionierung der Käfigstütze am Käfig 3 sicherstellen. Die Käfigstütze 13 weist außerdem zwei Abstützflächen 25 für die Unterriemchenführung 17 auf. Durch Käfigstützen 13, bei denen die Positionierung der Abstützflächen 25 unterschiedlich ist, lassen sich unterschiedliche Maulweiten im Streckwerk 10 einstellen. Je nach benötigter Maulweite wird die entsprechende Käfigstütze 13 ausgewählt und auf den Käfig 3 aufgeklipst. Die Käfigstütze 13 enthält Befestigungsmittel 26 zum Verbinden mit dem Käfig 3. Das Befestigungsmittel 26 ist in Form einer Aussparung ausgestaltet, die auf einen zapfenartigen Vorsprung 27 des Käfigs 3 aufklipsbar ist. Der Käfig 3 vor und nach dem Aufklipsen einer Käfigstütze 13 ist in den Figuren 5A und 5B erkennbar. Die Käfigstütze 13 enthält außerdem Befestigungsmittel 28 zum Verbinden mit einem Führungselement 14. Als Befestigungsmittel 28 dienen zwei zapfenartige Vorsprünge 29. Die Käfigstütze 13 enthält eine Aussparung 30, so dass der Käfig 3 zwischen den Abstützflächen 25 nicht vollständig abgedeckt wird. Ein Bereich der Vorderkante 35 bleibt von außen zugänglich.With the help of FIGS. 3 to 5 the inventive design of the cage support 13 and the guide member 14 is explained in more detail. The cage support 13 has a groove-shaped receptacle 23 for the cage 3. The cage support 13 is pushed with the receptacle 23 on a front edge 35 of the cage 3. The receptacle 23 includes support surfaces 24 which ensure positioning of the cage support on the cage 3. The cage support 13 also has two support surfaces 25 for the Unterriemchenführung 17. By cage supports 13, in which the positioning of the support surfaces 25 is different, different jaw widths in the drafting system 10 can be adjusted. Depending on the required mouth width, the corresponding cage support 13 is selected and clipped onto the cage 3. The cage support 13 includes attachment means 26 for connection to the cage 3. The attachment means 26 is configured in the form of a recess which can be clipped onto a pin-like projection 27 of the cage 3. The cage 3 before and after clipping a cage support 13 is in the FIGS. 5A and 5B recognizable. The cage support 13 also includes attachment means 28 for connection to a guide member 14. As a fastener 28 serve two pin-like projections 29. The cage support 13 includes a recess 30 so that the cage 3 between the support surfaces 25 is not completely covered. An area of the front edge 35 remains accessible from the outside.

Das Führungselement 14 weist Befestigungsmittel 31 zum Verbinden mit der Käfigstütze 13 auf. Die Befestigungsmittel 31 sind an die Befestigungsmittel 28 angepasst. Die Befestigungsmittel 31 werden durch Aussparungen gebildet, die auf die zapfenartigen Vorsprünge 29 aufklipsbar sind. Am Führungselement 14 ist eine Abstützfläche 32 angeordnet, die zur direkten Anlage am Käfig 3 dient. Hierdurch wird eine Positionierung der Führungsflächen 22 und 22' gewährleistet, die unabhängig von Herstellungstoleranzen der Käfigstütze 13 ist. Die Abstützfläche 32 ragt in die Aussparung 30 der Käfigstütze 13 hinein und stützt sich auf dem von der Aussparung 30 freigelassenen Bereich des Käfigs 3 ab. Das Hineinragen in die Aussparung 30 ist insbesondere in Figur 1B erkennbar. Die Befestigungsmittel 31, 28 sowie 26, 27 sind als Schnappverbindung ausgestaltet, so dass sich alle Teile sehr einfach und ohne Hilfswerkzeuge montieren und demontieren lassen. Wie insbesondere in den Figuren 4A und 4B erkennbar ist, werden die Führungsflächen 22 und 22' durch eine Stange 33 gebildet. Das Führungselement 14 weist einen Halter 34 auf, an dem die Befestigungsmittel 31 angeordnet sind. Der Halter 34 kann bevorzugt direkt an die Stange 33 angespritzt werden.The guide element 14 has attachment means 31 for connection to the cage support 13. The fastening means 31 are adapted to the fastening means 28. The fastening means 31 are formed by recesses which can be clipped onto the pin-like projections 29. On the guide member 14, a support surface 32 is arranged, which serves for direct contact with the cage 3. As a result, a positioning of the guide surfaces 22 and 22 'is ensured, which is independent of manufacturing tolerances of the cage support 13. The support surface 32 protrudes into the recess 30 of the cage support 13 and is supported on the area 30 of the cage 3 which has been released from the recess 30. The projecting into the recess 30 is in particular in FIG. 1B recognizable. The fastening means 31, 28 and 26, 27 are designed as a snap connection, so that all parts can be mounted and dismounted very easily and without auxiliary tools. As in particular in the FIGS. 4A and 4B recognizable, the Guide surfaces 22 and 22 'formed by a rod 33. The guide element 14 has a holder 34 on which the fastening means 31 are arranged. The holder 34 may preferably be molded directly onto the rod 33.

Im Falle einer Nachrüstung eines Führungselementes 14 an ein bestehendes Käfigaggregat 1 braucht nun der Käfig 3 nicht ausgetauscht werden. Es wird lediglich die vorhandene Käfigstütze des Käfigaggregates 1 entfernt und durch eine neue Käfigstütze 13 ersetzt. Die neue Käfigstütze 13 ist zur Aufnahme des Führungselementes 14 vorbereitet und an den vorhandenen Käfig 3 mit seinem zapfenartige Vorsprung 27 angepasst. Die neue Käfigstütze 13 stellt nun Befestigungsmittel 28 für ein Führungselement 14 zur Verfügung. Mit einer erfindungsgemäßen Käfigstütze 13 und einem zugehörigen Führungselement 14 lässt sich somit eine Nachrüstung bestehender Streckwerke 10 in sehr einfacher und kostengünstiger Art und Weise realisieren.In the case of a retrofit of a guide element 14 to an existing cage unit 1 now the cage 3 does not need to be replaced. Only the existing cage support of the cage assembly 1 is removed and replaced by a new cage support 13. The new cage support 13 is prepared for receiving the guide member 14 and adapted to the existing cage 3 with its pin-like projection 27. The new cage support 13 now provides fastening means 28 for a guide element 14. With a cage support 13 according to the invention and an associated guide element 14, it is thus possible to retrofit existing drafting systems 10 in a very simple and cost-effective manner.

In nicht dargestellter Ausgestaltung kann selbstverständlich auch vorgesehen sein, dass das Führungselement 14 zuerst auf den Käfig 3 aufgesetzt und am zapfenartigen Vorsprung 27 befestigt wird. In einem solchen Fall sind dann Befestigungsmittel zum Verbinden mit einer Käfigstütze vorgesehen, die eine Befestigung einer Käfigstütze an dem Führungselement 14 ermöglichen würden.In an embodiment not shown can of course also be provided that the guide member 14 is first placed on the cage 3 and attached to the pin-like projection 27. In such a case, then fastening means are provided for connection to a cage support, which would allow attachment of a cage support to the guide member 14.
