Grundierungsbelag"für KaraentromraelnPrimer coating "for Kara drums

Kardentrommeln sind üblicherweise mit einer mehrlagigen Grundierung versehen, deren Lagen aus Baumwollgewebe und Leinen bestehen, die durch vulkanisierten Gummi, künstlichen Gummi oder Kunststoffkleber festhaftend verbunden sind. Die Gewebelagen sollen dabei der Grundierung die erforderliche Stabilität verleihen. Card drums are usually provided with a multi-layer primer, the layers of which are made of cotton fabric and linen that are firmly bonded by vulcanized rubber, artificial rubber or plastic glue. The fabric layers should give the primer the necessary stability.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Grundierung für Kardenwalzen zu schaffen.The invention is based on the object of creating an improved primer for card rollers.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Grundierung wenigstens eine Schicht aus Kunststoffolie enthält. Der Begriff "Kunststoffolie" bezieht sich auf Kunststoff, insbesondere polymeren Kunststoff, der durch Verziehen oder Strangpressen in dünner Schicht hergestellt ist. Die Kunststofffolie verleiht der Grundierung eine Stabilität in wenigstens einer Hichtung und kann daher als Ersatz für ein Leinen« oder Baumwollgewebe verwendet werden. Durch die Benutzung einerThis object is achieved according to the invention in that the primer contains at least one layer of plastic film. The term "plastic film" refers to plastic, in particular polymeric plastic which is produced in a thin layer by warping or extrusion. The plastic film gives the primer stability in at least one direction and can therefore be used as a substitute for a linen «or Cotton fabrics are used. By using a

-Folienschicht aus Kunststoff wird ein besseres und besser haltbares Setzen der Kratzenzinken erreicht, da sich die Kratzendrähte in die Kunststoffolie leichter einziehen lassen als in Leinen- oder Baumwollgewebe. Von der besonderen Eigenschaft des leichteren Einziehens der Kratzen in Kunststoffolie hat man bisher keinen Gebrauch gemacht.-Film layer made of plastic will be a better and more durable one Setting of the scraper teeth achieved because the scraper wires can be drawn into the plastic film more easily than in Linen or cotton fabric. The special property of easier drawing in of the scratches in plastic film has been known so far made no use.

In bevorzugter Ausführung besteht die Folienschicht aus einem aus flachem Kunststoffband drehungslos hergestellten Flachgewebe, dessen sich kreuzende Bänder praktisch ohne Spalträume dicht zusammenliegen. Das Kunststoffband besteht zweckmäßig aus Polypropylen, kann Jedoch auch aus anderen Polymeren bestehen, z.B. aus Polyester, Polyamid, Acrylen od.dgl.In a preferred embodiment, the film layer consists of a non-rotating manufactured from flat plastic tape Flat woven fabric, the intersecting bands of which lie close together with practically no gaps. The plastic tape is expedient made of polypropylene, but can also consist of other polymers, e.g. polyester, polyamide, acrylics or the like.

In bevorzugter Ausführung der Erfindung ist weiterhin die Folienschicht mit einer Gewebeschicht ausgerüstet, beispielsweise mit einem Baumwollgewebe oder mit einer Gewebeschicht, die mit vulkanisiertem Gummi beschichtet oder mit einer sonstigen Ausrüstung versehen ist.In a preferred embodiment of the invention, the film layer is also equipped with a fabric layer, for example with a cotton fabric or with a fabric layer coated with vulcanized rubber or with another Equipment is provided.

Fig. 4 einen Schnitt durch einen Abschnitt der Kardengrundierung nach der Erfindung in stark vergrößerter Darstellung.4 shows a section through a section of the card primer according to the invention in a greatly enlarged representation.

Die Kardengrundierung besteht aus einem Schichtkörper, der aus einem in Fig. 1 dargestellten Baumwollgewebe 10 und einem in Fig. 2 dargestellten Flachgewebe 11 aus Kunststofffolie aufgebaut ist. Das Flachgewebe besteht zweckmäßig aus einem Folienband aus Polypropylen, das zunächst als Bahn hergestellt und dann in schmale Streifen zerschnitten wird, die dann wie bei einem Gewebe als sich kreuzende Kettenbänder 12 und Schui3bänder 13 verarbeitet sind, und zwar in solcher Weise, daß beim Verarbeiten keine Verdrehung der Bänder eintritt. Derartige Flachgewebe aus Kunststoff sind handelsüblich und bedürfen daher keiner näheren Beschreibung. Es sei jedoch bemerkt,-daß das durch Strangpressen hergestellte Folienband aus Polypropylen in Längsrichtung sehr fest und haltbar, in seitlicher Richtung aber weniger fest ist und leicht durchlocht werden kann, Ein daraus hergestelltes Flachgewebe gemäß Fig. 2 ist daher in beiden sich kreuzenden Richtungen sehr fest und weist praktisch keine Zwischenräume zwischen den Folienbändern auf. Diese Eigenschaften sind für die Kardengrundierung wichtig.The card primer consists of a layered body, of a cotton fabric 10 shown in Fig. 1 and a flat fabric 11 shown in Fig. 2 made of plastic film is constructed. The flat woven fabric expediently consists of a film strip made of polypropylene, which is initially produced as a web and then cut into narrow strips, which are then, as in the case of a fabric, as intersecting chain bands 12 and Schui3band 13 are processed, in such a way, that no twisting of the bands occurs during processing. Such flat fabrics made of plastic are commercially available and require therefore no further description. It should be noted, however, that the film strip produced by extrusion is made of polypropylene very strong and durable in the longitudinal direction, but less strong in the lateral direction and can be easily perforated, A flat woven fabric produced therefrom according to FIG. 2 is therefore very strong in both intersecting directions and is practical there are no gaps between the foil strips. These properties are important for the card primer.

Das Baumwo11gewebe muß mit dem Flachgewebe aus Polypro« pylenfolie verbunden werden. Hierfür werden Abschnitte des Baumwollgewebes und des Flachgewebes aus Kunststoff von zwei parallelen Vorratsrollen I^ und 15 abgezogen und durch die Klemmstelle von zwei zusammenliegenden, beheizten Kalander-The cotton fabric must be matched with the flat fabric made of polypropylene. pylene film are connected.

Die Kalanderwalzen sind an ihren Enden natürlich mit überstehenden Stirnplatten versehen, so daß das geschmolzene Polypropylen nicht aus den Walzen ablaufen kann. Die Temperatur der Kalan*- derwalzen wird mit Bezug auf die Umfangsgeschwindigkeit der Walzen so eingestellt, daß das geschmolzene Polypropylen zwischen den Walzen im flüssigen Zustand bleibt, das Flachgewebe aus Kunststoffolie aber nicht geschmolzen wird« Nach dem Durchlaufen der Kalanderwalzen verfestigt sich das geschmolzene Polypropylen, und der gebildete Schichtstoff wird dann um mehrere Führungsrollen 18 geleitet, um ihn auf Raumtemperatur zu kühlen, ehe er auf eine Aufwickeltrommel 22 kommt. Zweck der Behandlung ist es, die beiden Webschichten fest miteinander zu verbinden.rollers l6 passed through, molten polypropylene, which is melted from heated propylene cuttings, passed by a heating device 19 with a nozzle 17 between the calender rolls 16 in the Kiemrastelle of these rolls, so that the cotton fabric 10 and the flat fabric 11 at their facing surfaces are wetted and glued. The calender rolls are of course with protruding ends at their ends Provided face plates so that the molten polypropylene cannot run off the rollers. The temperature of the Kalan * - derwalzen is adjusted with respect to the peripheral speed of the rollers so that the molten polypropylene between the rollers remains in the liquid state, but the flat woven plastic film is not melted «after passing through As the calender rolls solidify, the molten polypropylene solidifies, and the laminate that is formed then turns around guided several guide rollers 18 to cool it to room temperature before it comes to a winding drum 22. purpose the treatment is to firmly join the two layers of weave together.

Ist dies geschehen, so wird die Behandlung wiederholt, um die andere Seite des Polypropylengewebes mit einer anderen Schicht aus Baumwollgewebe 20 zu verbinden (s. Fig. ^). Man kann dann auf bekannte Weise, z.B. mit Gummizement, diese mehrlagige Schicht mit anderen Schichten aus Baumwollgewebe, Polyvinylchlorid, Acrylonnitril oder sonstige bekannte Grundierungslagen 21 (Fig. 4·) versehen, um auf diese Weise eine mehr-Once this is done, the treatment is repeated to the other side of the polypropylene fabric with another To connect layer of cotton fabric 20 (see Fig. ^). Man can then in a known way, e.g. with rubber cement, this multilayered layer with other layers of cotton fabric, polyvinyl chloride, Acrylonitrile or other known primer layers 21 (Fig. 4) are provided in order to achieve a multiple

Bekannte Grundierungsmaterialien wie Polyvinylchlorid oder Acrylonnitril werden in Gestalt relativ dicker Platten verwendet, die expandiert oder verschäumt sein können,create a layered base layer into which the card scrapers are inserted can be. Known primer materials such as polyvinyl chloride or acrylonitrile are relative in shape thicker sheets are used, which can be expanded or foamed,

Die Polypropylenschicht ist nicht nur billiger als eine Schicht aus Leinengewebe, sondern weist in ihren Abmessungen auch eine bessere Stabilität auf, da sie nicht einläuft, läßt sich auch leicht durchlochen und gestattet daher ein besonders leichtes Einziehen der Kardenkratzen. Die Kratzen werden von der Oberseite der in Fig. 4 dargestellten, mehrschichtigen Grundierung her eingezogen. Die obere Schicht 10 aus Baumwollgewebe setzt dem Einziehen der Kratzen nur einen geringen Widerstand entgegen, und dies gilt auch für die Schicht 11 des Folienflachgewebes, dessen Dicke vernachlässigbar ist, weil es sich leicht durchlochen läßt, aber den in die Grundschicht eingezogenen Kratzen eine gute Haltbarkeit und Lagenstabilität verleiht und hierdurch auch das Einziehen der Kratzen erleichtert. The polypropylene layer is not only cheaper than a layer of linen fabric, but it is also great in its dimensions also a better stability, since it does not shrink, can also be easily perforated and therefore allows a special easy drawing in of the card scrapers. The scratches are from the top of the multilayer shown in FIG Primer pulled in. The upper layer 10 made of cotton fabric offers little resistance to the scratches being drawn in contrary, and this also applies to the layer 11 of the foil flat fabric, the thickness of which is negligible, because it can be perforated easily, but that which is drawn into the base layer Scratching gives good durability and layer stability and thereby also makes it easier for the scratches to be drawn in.
