Embodiment Construction

[0035] According to the invention, the cable making device 10 used for this purpose comprises in series on the same production line: first a twist-free combining station 11 suitable for joining the two wires f1, f2 without twisting them individually; The resulting combination undergoes at least one twisting station 12 of twisting.

[0036] In the embodiment shown, the twist-free assembly station 11 comprises at least one bridge 13 in addition to the first release reel B1 from which the electric wire f1 is paid out. In practice, the bridge 13 is formed by a combination device 14 in which there is a second release reel B2 from which the electric wire f2 is paid out.

[0037] Since this example only involves the production of a single twisted pair, there is only one bridge frame 13 .

[0038] As shown in FIG. 1 , for example, the combination device 14 of the bridge 13 is a bracket-shaped combination device.

[0039] The combination device 14 comprises a bracket-shaped frame 15 ...

Abstract

The invention relates to a method which consists in using a twist-free combining station (11) on the same production line, where the various necessary wires (f1, f2, etc.) can be combined without twisting the wires individually; Twisting station (12), where the cable (c) formed as a whole by the wires (f1, f2, etc.) is twisted at least once. The invention is particularly useful in the production of twisted pairs.

Description

technical field [0001] The present invention generally relates to electrical cables made by twisting one or more wires to form litz wires. [0002] The invention relates more particularly where the wires are the insulated conductors of the cable, and even more particularly, though not necessarily exclusively, where only two wires are used and the resulting cable is commonly referred to as a twisted pair. Background technique [0003] It is well known that a twist that uses two wires together to combine them into a twisted wire typically also twists each of the two wires individually. [0004] It is also known that a pair of insulated conductive wires constitutes a capacitor, and its impedance depends not only on the frequency of the electrical signal transmitted, which rapidly becomes non-negligible when the frequency is relatively high, but also on the distance between the two wires. capacitance between. [0005] Finally, it is also known that this capacitance itself depe...
