Description
Es ist bei Femsprechkabeln mit Papierisolation bekannt, die Papierhülle in der Weise unter Abstand von der Leitungsader zu halten, daß über diese Leitungsader zunächst (ein Papierband mit beiderseitig- eingerollten Kanten und !hierüber eine normale Papierbespinnung aufgetragen werden·.It is in the case of telephony cables with paper insulation known, the paper sleeve in such a way at a distance from the line core to keep that this line core initially (a paper tape with both sides rolled up Edges and! Over this a normal paper covering can be applied.
Die Erfindung! betrifft nun eine andere Ausbildung dnes derartigen papierisoHerten Kabels. Gemäß der Erfindung wird als abstandhaltendes Mittel ein Papierband verwendet, in dessen beiderseitig eingerollten Kanten ein Faden eingelegt ist. Durch diesen eingelegten Faden wird die Widerstandsfähigkeit des Bandes, insbesondere wenn es aus Papier besteht, wesentlich erhöht, 90 daß die Gefahr des Reißens des Bandes beim! Aufbringen desselben auf die Leitungsader: beseitigt wird..The invention! now concerns a different training such a paper-insulated cable. According to the invention, a paper tape is used as the spacing means, in which it is rolled up on both sides A thread is inserted into the edges. This inlaid thread increases the resistance of the tape, especially if it is made of paper, significantly increased 90 that the danger of tearing the tape when! Applying the same to the line core: is eliminated ..
In der Abbildung ist .ein Ausführungsbeispiel der Erfindung dargestellt. 1 ist die Leitungsader über 'die das Papierband1 2 mit eingerollten Kanten 3 und 4 schraubenförmig gewickelt ist. In die eingerollten Kanten sind 'die Fäden 5 und 6 gelegt. Über dem Band ist eine Papierbespinnung 7 aufgebracht, die auch unter Umständen aus anderem Material als Papier bestehen kann. Die Fläche des Papierbandes kann dabei der Papierbespinnung oder der Ader zügekehrt sein. Das Band wird zweckmäßig aus Papier hiergestellt, doch kann auch anderes Material mit den Zwecken entsprechenden Eigenschaften statt Papier gewählt werden..In the figure, an embodiment of the invention is shown. 1 is the line wire over which the paper tape 1 2 with rolled-up edges 3 and 4 is helically wound. The threads 5 and 6 are placed in the rolled edges. A paper covering 7 is applied over the tape, which under certain circumstances can also consist of a material other than paper. The surface of the paper tape can be facing the paper or the wire. The tape is expediently made of paper here, but other materials with the appropriate properties can also be selected instead of paper.
