Description

Um einen elektrischen Leiter mit Band zu umhüllen, ist ein Verfahren bekanntgeworden, bei dem, das Band in seiner Längenerstreckung am Leiter angeheftet und dann im Querschnitt gesehen nach einer Spirale in einer oder mehreren Windungen um den Leiter geschmiegt wird. Auf diese Weise kann man sowohl einen Leiter isolieren als auch auf den schon isolierten Leiter oder die isolierte Kabelseele einen Mantel aufbringen. Für das genannte Verfahren ist unter anderem eine Vorrichtung gebräuchlich, die aus einer schraubenlinienförmig verlaufen den Rinne besteht. Der Leiter wird zusammen mit dem längs seiner einen Mantellinie angehefteten Band :durch die Rinne hindurchgezogen, wobei das Band auf dem Wege durch die Rinne stetig fortschreitend um den Leiter geschmiegt wird.One method is to wrap an electrical conductor with tape became known in which, the tape is attached in its length to the conductor and then seen in cross section after a spiral in one or more turns is nestled around the ladder. In this way you can isolate both a conductor as well as a jacket on the already insulated conductor or the insulated cable core raise. Among other things, a device is common for the process mentioned, which consists of a helical groove extending into the groove. The leader will together with the tape attached along one of its surface lines: through the gutter pulled through, the tape steadily advancing on the way through the channel is nestled around the ladder.

Mitunter reicht der Anpreßdruck, den Leiter und Band in der Rinne erfahren, nicht aus, um das Band genügend fest um den Leiter zu schmiegen. Es entsteht dann eine lockere Umhüllung. Nach der Erfindung läßt sich dieser Nachteil vermeiden. Erfindungsgemäß ist die Anordnung derart. getroffen, daß der radiale Abstand der schraubenlinienförmig verlaufenden Rinne von der Achse der Schraubenlinie von den Enden nach der Mitte hin zunimmt. Dadurch wird der Anpreßdruck- zwischen Leiter und Rinne vergrößert, und .das Band wird fester auf . den Leiter aufgelegt. Wie es sich ,gezeigt hat, ist es besonders vorteilhaft, wenn der radiale Abstand der Rinne von der Achse der Schraubenlinie in der Mitte etwa doppelt so groß ist wie an den. Enden und die Rinne auf einem Rotationskörpef mit einem Kreisbogen als Erzeugenden verläuft.Sometimes the contact pressure is enough, the ladder and tape in the gutter experienced, not enough to nestle the tape tight enough around the ladder. It arises then a loose wrap. According to the invention, this disadvantage can be avoided. According to the invention, the arrangement is such. taken that the radial distance of the helical groove from the axis of the helix of the Increases towards the middle. This is the contact pressure between conductors and groove is enlarged, and the tape becomes tighter. the ladder hung up. As it has been shown, it is particularly advantageous if the radial distance of the Groove from the axis of the helix in the center is about twice as large as to the. Ends and the channel on a body of revolution with an arc of a circle as the generatrix runs.

Die Zeichnung zeigt beispielsweise eine Ausführungsform der Vorrichtung nach der Erfindung. Die schraubenlinienförmig verlaufende Rinne i ist in den Mantel des Rotationskörpers 2 eingearbeitet, dessen Erzeugende von einem Kreisbogen gebildet wird, und dessen Durchmesser in. der Mitte doppelt so groß ist wie an den Enden.The drawing shows, for example, an embodiment of the device according to the invention. The helical groove i is in the jacket of the body of revolution 2 incorporated, the generatrix of which is formed by an arc of a circle and its diameter in the middle is twice as large as at the ends.
