EMI1.1
Das Stammpatent Nr. 113587 hat zum Gegenstand ein Verfahren zur Herstellung von Fernmeldekabeln mit vermindertem Nebensprechen, bei dem innerhalb einzelner Mehrfachadern je zwei Adern in ihrer örtlichen Lage ohne Zerschneiden derselben über eine durch Messung festgelegte Strecke vertauscht werden.
Dieses Verfahren lässt sieh gemäss der Erfindung auch auf Mehrfachadern höherer Ordnung ausdehnen, die beispielsweise aus Doppelvierern, Doppelachtern usw. bestehen. In diesem Fall werden nicht zwei Einzeladern, sondern vielmehr zwei Verseilelemente höherer Ordnung, d. h. Doppeladern oder - vierer usw. miteinander ohne Zerschneiden vertauscht. Die Vertauschung der Verseilelemente kann nach der Fertigstellung der auf Fabrikationslänge fertig verseilten Mehrfachadern höherer Ordnung oder auch gemäss Patent Nr. 113587 schon während der Herstellung der Mehrfachadern höherer Ordnung vorgenommen werden.
In den Abbildungen sind einige Ausführungsbeispiele dargestellt. In Fig. 1 sind vier Mehrfach- adern 1-4 um eine gemeinsame Achse so verseilt, dass sich ein Querschnitt am Punkt J. ergibt, wie
EMI1.2
vertauscht sind, ist in der Mitte der Fig. 1 gezeigt. Die Anordnung der Mehrfachadem im Punkt D s : eht aus der Fig. 3 hervor. Fig. 4 und 5 zeigen die gleichen Querschnitte an den Punkten A und B, jedoch für eine andere Art von Mehrfachadern.

EMI1.1
The subject of the parent patent no. 113587 is a process for the production of telecommunication cables with reduced crosstalk, in which, within individual multiple cores, two cores are interchanged in their local position without cutting them over a distance determined by measurement.
According to the invention, this method can also be extended to multiple cores of a higher order, which for example consist of double fours, double eights, etc. In this case, not two single strands, but rather two higher-order stranding elements, i.e. H. Twins or fours, etc. interchanged without cutting. The interchanging of the stranding elements can be carried out after the completion of the stranded multiple cores of a higher order to the production length or, according to patent no. 113587, already during the manufacture of the multiple strands of the higher order.
Some exemplary embodiments are shown in the figures. In FIG. 1, four multiple wires 1-4 are stranded around a common axis in such a way that a cross section results at point J.
EMI1.2
are interchanged is shown in the middle of FIG. The arrangement of the multiple wires at point D s: ehts from FIG. 3. Figures 4 and 5 show the same cross-sections at points A and B, but for a different type of multiple cores.
PATENT CLAIMS:
EMI1.3
(Two-wire or four-wire) can be interchanged without cutting.
