Description

Verfahren zur Herstellung von Fernsprechkabeln Die hohen Anforderungen, welche neuerdings an Fernsprechkabel gesellt werden, machen es notwendig, die einzelnen Elemente des Kabels; also z. B. die Adergruppen, wie Vierer u. dgl, während der Herstellung vorzumessen. Diese Vormessung erstreckt sich außer auf die Messung der Leiterwiderstände vor allem auf die Kopplungen und gegebenenfalls auf die Betriebskapazitäten. Die Genauigkeit der Messung der Kapazitäten und Kopplungen ist nun sehr stark von den Isolationswiderständen und Verlustwinkeln. zwischen den Adern der Gruppe abhängig. Erfolgt die Vormessung an gänzlich urgetrockneten Gruppen, so sind unter Umständen die Isolationswiderstände und Verlustwinkel für jede Ader verschieden, da der Feuchtigkeitsgrad jeder Ader verschieden ist. Deshalb werden die Messungen bekanntlich an getrockneten Adergruppen vorgenommen.Process for the production of telephone cables The high requirements, which have recently been added to telephone cables make it necessary for the individual Elements of the cable; so z. B. the vein groups, such as fours and the like, during the Measure production. This preliminary measurement extends to the measurement of the Conductor resistances mainly on the couplings and, if necessary, on the operating capacities. The accuracy of the measurement of the capacitances and couplings is now very strong the insulation resistance and loss angles. between the cores of the group. If the preliminary measurement is carried out on groups that have completely dried out, then under certain circumstances The insulation resistance and loss angle are different for each wire because of the degree of humidity every vein is different. Therefore, as is known, measurements are made on dried Core groups made.

Gemäß der Erfindung wird die Ausgleichung des Feuchtigkeitsgrades der fertigbesponnenen Adern. dadurch vorgenommen, daß die Adern durch einen Kautal laufen, in dem sie getrocknet werden. Die Adern werden auf der einen Seite des Kanals ab- und auf der anderen Seite wieder aufgewickelt, sie können einzeln oder zu mehreren gleichzeitig durch den Kanal laufen. Vorteilhaft werden die zu derselben Gruppe gehhörigen Adern gleichzeitig hindurchgeführt.According to the invention, the equalization of the degree of humidity of the ready-spun veins. made by the fact that the veins through a Kautal run in which they are dried. The veins are on one side of the duct unwound and wound up on the other side, they can be individually or in groups run through the canal at the same time. It would be advantageous if they belong to the same group belonging veins passed through at the same time.

Die Trocknung im Kabel erfolgt in bekannter Weise mittels Erwärmung von außen, durch Stromerwärmung in den Adern selbst, durch Hindurchblasen von trockener Luft oder auf andere beliebige Weise. Die Länge des Kanals und die Durchzugsgeschwindigkeit richten sich nach den Anforderungen, die an die Gleichheit in bezug auf den Feuchtigkeitsgrad der Adern gestellt werden, und werden durch Erfahrung festgestellt.The drying in the cable takes place in a known manner by means of heating from the outside, by heating the current in the veins themselves, by blowing through them from drier ones Air or any other means. The length of the duct and the speed of passage are based on the requirements for equality in terms of the degree of moisture of the veins, and are determined by experience.

Das angegebene Verfahren hat den großem Vorteil, daß der Ausgleichsvorgang beschleunigt wird,denn durch das Auf- und Abwickeln werden nacheinander alle Teile der Adern freigelegt, so daß die Feuchtigkeit heraus kann.The specified method has the great advantage that the equalization process is accelerated, because by winding and unwinding all parts one after the other the veins exposed so that the moisture can come out.

Der Trockenkanal kann auch direkt an der Aderspinnmaschine angebracht werden, so daß ein besonderer Arbeitsgang für das Durchziehen in Fortfall kommt.The drying tunnel can also be attached directly to the vein spinning machine so that a special operation for pulling through is eliminated.
