Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von elektrischen Leitungen mit dünnen Überzüügen aus einem warm verformbaren Isolierstoff, beispielsweise Polyvinylchlorid. Bei den bisher bekannten Verfahren wurde entweder der Isolierstoff in Form von Schlääuchen über den Draht gezogen und durch Erwärmen und gegebenenfalls durch gleichhzeitiges Fetspressen eine feste Verbindung zwischen dem Leiter und der Isolierung geschaffen, oder es wurde der Isolierstoff in Bandform mittels einer Führung längs um den Leiter herumgelegt und die Ränder durch Wärmeanwendung miteinander verschmolzen. In beiden Fällen ergeben sich aber verhältnismäßig dicke Isolierschichten. The invention relates to a method for producing electrical cables with thin coatings made of a thermally deformable insulating material, for example polyvinyl chloride. In the previously known method either the insulating material is drawn over the wire in the form of hoses and heated and, if necessary, by simultaneous pressing a firm connection between the conductor and the insulation created, or it was the insulating material in tape form placed lengthways around the conductor by means of a guide and the edges by applying heat fused together. In both cases, however, the result is relatively thick Insulating layers.
Die Erfindung macht Gebraucht von dem letztgenannten Verfahren. Zur Erzielung besonders dünner Überzüge wird aber erfindungsgemäß der Isolierstoff mittels einer beheizten Düse auf dem der Düse mit größerer Geschwindigkeit als das Band zugeführten Leiter dünnengezogen. The invention makes use of the latter method. To the However, according to the invention, the insulating material is achieved by means of particularly thin coatings a heated nozzle on top of the nozzle at a faster speed than the belt fed conductor thin drawn.
Die Erfindung wird an Hand des in der Zeichnung dargestellten Beispiels näher erläutert. The invention is based on the example shown in the drawing explained in more detail.
I ist der Leiter, der von einer Vorratsrolle in der Pfeilrichtung auf eine Trommel aufgewickelt wird. Auf einer Vorratsrolle 2 befindet sich ein Film aus Polyvinylchlorid. Der Filmstreifen läuft mit dem Draht 1 in eine Führung 3 ein, die den Streifen als Mantel, am besten unter Überlappung der Ränder um den Draht I legt, ìuind zwar so lose, daß der Draht durch das Innere des Mantels hindurchwandern kann, 4 ist eine elektrisch beheizte Düse, den Innendurchmesser nur wenig größer ist als der Drahtdurchmesser. Sie drückt einerseits den Mantel gegen den Draht fest, andererseits bewirkt sie, daß beim Durchziehen des Drahtes der Mantel auf dem Dnaht dünngezogen wird. Auf diese Weise wird eine sehr dünnen, elektrisch gleichmäßige und mechanisch widerstandsfähige Isolierung erhalten. I is the head that comes from a supply roll in the direction of the arrow is wound on a drum. A film is located on a supply roll 2 made of polyvinyl chloride. The film strip runs with the wire 1 into a guide 3, covering the strip as a coat, preferably by overlapping the edges around the wire I lay so loosely that the wire can wander through the inside of the jacket can, 4 is an electrically heated nozzle, the inner diameter only slightly larger is than the wire diameter. On the one hand, she presses the jacket against the wire, on the other hand, it has the effect that when the wire is pulled through, the sheath on the seam is drawn thin. In this way it becomes a very thin, electrically uniform one and mechanically resistant insulation.
