Description

Die Erfindung betrifft einen Drehteller für eine Strecke mit einem Faserbandkanal, der in einer Verdichtungsfläche mündet, die mit einer Beschichtung versehen ist und ein Verfahren zum Beschichten der Verdichtungsfläche.The invention relates to a turntable for a draw frame with a sliver channel that opens into a compression surface that is provided with a coating and a method for coating the compression surface.

Um die Reibung zwischen der Verdichtungsfläche des Drehtellers einer Strecke und des darunter befindlichen, in einer Kanne ab­gelegten Faserbandpaketes zu verringern, sind verschiedene Maß­nahmen bekannt geworden. Beispielsweise ist es bekannt (DE-A-­34 07 136), die Verdichtungsfläche durch eine Platte zu erset­zen, die in dem Drehteller drehbar gelagert ist und die somit von der Drehbewegung des Drehtellers unabhängig ist. Es ist auch bekannt geworden, die Verdichtungsfläche des Drehtellers mit einer Beschichtung in Form einer Teflonfolie zu versehen. Diese Beschichtung mit einer Teflonfolie erlaubt zwar einen ge­ringen Reibwert, jedoch hat sie keine ausreichende Standzeit. Weiter ist es auch bekannt, die Verdichtungsfläche und auch den Faserbandkanal zu verchromen. Dabei ist es jedoch notwendig, die Verdichtungsfläche und auch den Faserbandkanal vor dem Ver­chromen zu schleifen und/oder zu polieren, was einen erhebli­chen Aufwand erfordert.Various measures have become known in order to reduce the friction between the compression surface of the turntable of a draw frame and the fiber sliver package located underneath it and placed in a can. For example, it is known (DE-A-34 07 136) to replace the compaction surface with a plate which is rotatably mounted in the turntable and which is therefore independent of the rotary movement of the turntable. It has also become known to provide the compaction surface of the turntable with a coating in the form of a Teflon film. This coating with a Teflon film allows a low coefficient of friction, but it does not have a sufficient service life. It is also known to chrome-plate the compression surface and also the sliver channel. However, it is necessary to grind and / or polish the compression surface and also the sliver channel before chrome plating, which requires considerable effort.

Der Erfindung liegt die Aufgabe zugrunde, einen Drehteller mit einer einfach anzubringenden Beschichtung zu versehen, die gute Gleiteigenschaften aufweist und eine ausreichende Standzeit be­sitzt.The invention has for its object to provide a turntable with an easy-to-apply coating that has good sliding properties and has a sufficient service life.

Diese Aufgabe wird dadurch gelöst, daß die Verdichtungsfläche mit einer Emaillebeschichtung versehen ist.This object is achieved in that the compaction surface is provided with an enamel coating.

Eine derartige Emaillebeschichtung besitzt einen relativ gerin­gen Reibungsbeiwert bezüglich Fasern, so daß eine geringe Rei­bung ausgeübt wird. Außerdem ist eine derartige Emaillebe­schichtung elektrostatisch nicht aufladbar, was zu erheblichen Vorteilen führt. Zudem bietet diese Emaillebeschichtung eine ausreichende Verschleißfestigkeit. Ein besonderer Vorteil be­steht auch darin, daß diese Emaillebeschichtung mit einer rela­tiv großen Dicke aufgebracht werden kann, beispielsweise mit einer Dicke von 0,5 mm, wobei eine glatte Oberfläche erzeugt wird, ohne daß die darunter liegende Fläche sehr fein bearbei­tet werden muß.Such an enamel coating has a relatively low coefficient of friction with respect to fibers, so that little friction is exerted. In addition, such an enamel coating cannot be charged electrostatically, which leads to considerable advantages. In addition, this enamel coating offers sufficient wear resistance. A particular advantage is also that this enamel coating can be applied with a relatively large thickness, for example with a thickness of 0.5 mm, a smooth surface being produced without the surface underneath having to be processed very finely.

In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß die Beschichtung sich über die Innenwände des Faserbandkanals erstreckt.In a further embodiment of the invention it is provided that the coating extends over the inner walls of the sliver channel.

In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß der Drehteller mit seiner Verdichtungsfläche und einem in der Verdichtungsfläche mündenden Faserbandkanal in eine Emaille-­Schmelze eingetaucht wird, die anschließend eingebrannt wird. Ein derartiges Emaille-Beschichten der Verdichtungsfläche und des Faserbandkanals läßt sich mit relativ geringem wirtschaft­lichem Aufwand verwirklichen.In a further embodiment of the invention it is provided that the turntable with its compression surface and a sliver channel opening into the compression surface is immersed in an enamel melt, which is then baked. Such an enamel coating of the compression surface and the sliver channel can be achieved with relatively little economic effort.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels.Further features and advantages of the invention result from the following description of an exemplary embodiment.

In der Zeichnung ist ein Axialschnitt durch einen nur schema­tisch dargestellten Drehteller gezeigt.In the drawing, an axial section through a turntable shown only schematically is shown.

Der in der Zeichnung dargestellte Drehteller ist beispielsweise als ein Metallgußteil hergestellt. Er besitzt einen etwa axial beginnenden Faserbandkanal, in welchen das in einer nicht dar­gestellten Kanne abzulegende Faserband einläuft, das in dem Fa­serbandkanal (11) etwas verdichtet wird. Der Faserbandkanal (11) mündet in einer Verdichtungsfläche (10), die auf dem in einer Kanne abzulegenden Faserbandpaket aufliegt und dieses verdichtet. Der Drehteller rotiert um eine nicht dargestellte vertikale Achse.The turntable shown in the drawing is made, for example, as a metal casting. It has an approximately axially starting sliver channel into which the sliver to be deposited in a can (not shown) runs in, which is somewhat compressed in the sliver channel (11). The sliver channel (11) opens into a compression surface (10) on the in a sliver package to be put down rests and compresses it. The turntable rotates about a vertical axis, not shown.

Um die Reibung zwischen Verdichtungsfläche (10) und dem da­runter befindlichen Faserbandpaket zu verringern, ist die Ver­dichtungsfläche (10) mit einer Beschichtung (12) aus Emaille vorgesehen, die sich auch über die gesamten Innenwände des Fa­serbandkanals (11) erstreckt. Die Beschichtung (12) läuft seit­lich auch über den Rand der Verdichtungsfläche (10) aus und be­deckt wenigstens teilweise die daran anschließenden Seitenflä­chen.In order to reduce the friction between the compression surface (10) and the sliver package underneath, the compression surface (10) is provided with a coating (12) made of enamel, which also extends over the entire inner walls of the sliver channel (11). The coating (12) also runs out laterally over the edge of the compression surface (10) and at least partially covers the adjoining side surfaces.

Die Emaillebeschichtung (12) wird dadurch angebracht, daß der Drehteller mit der Verdichtungsfläche (10) und dem Faserband­kanal (11) in eine Emaille-Schmelze eingetaucht wird. Die nicht zu beschichtenden Bereiche werden abgedeckt. Anschließend wird diese Emaille-Schmelze bei hoher Temperatur von 900°C und mehr eingebrannt. Um eine besondere Glättung der Oberfläche zu er­zielen, wird auf die zunächst angebrachte Schicht ein Emaille­pulver aufgestreut, das anschließend ebenfalls eingebrannt und eingeschmolzen wird, so daß sich eine besonders glatte Oberflä­che ergibt. Besonders zweckmäßig ist es, wenn ein feinkörniges Emaille verwendet wird.The enamel coating (12) is applied by immersing the turntable with the compression surface (10) and the sliver channel (11) in an enamel melt. The areas not to be coated are covered. This enamel melt is then baked at a high temperature of 900 ° C and more. In order to achieve a special smoothing of the surface, an enamel powder is sprinkled onto the initially applied layer, which is then also baked and melted down, so that a particularly smooth surface is obtained. It is particularly useful if a fine-grained enamel is used.

Die Emaillebeschichtung (12) läßt sich mit einer relativ star­ken Schichtdicke aufbringen, beispielsweise einer Schichtdicke von 0,5 mm. Dadurch werden Rauhigkeiten der darunter liegenden Oberfläche abgedeckt und geglättet. Es ist somit nicht notwen­dig, die Verdichtungsfläche (10) und auch die Innenwände des Faserbandkanals (11) besonders fein zu bearbeiten, beispiels­weise zu schleifen oder zu polieren, um eine ausreichende Glät­te und damit einen geringen Reibungsbeiwert zu erzielen.The enamel coating (12) can be applied with a relatively thick layer, for example a layer of 0.5 mm. As a result, roughness of the underlying surface is covered and smoothed. It is therefore not necessary to process the compression surface (10) and also the inner walls of the sliver channel (11) particularly finely, for example grinding or polishing, in order to achieve sufficient smoothness and thus a low coefficient of friction.
