Definitions
- the present invention relates generally to cables made by twisting in strand of one or more son.
- these wires are insulated electrical conductors, and, more particularly still, but not necessarily exclusively, the case where, only two wires being used, the cable constitutes what is more commonly called a pair.
- a pair of insulated conductor wires generally constitutes a capacitor, the impedance of which depends not only on the frequency of the electrical signals conveyed, becoming moreover very quickly not insignificant when this frequency is it - even relatively high, but also of the capacitance between the two wires.
- this capacitance itself depends on the nature of the dielectric material constituting the insulating sheath of these two wires and on the thickness of this insulating sheath.
- this thickness is not strictly constant throughout the periphery of the wires.
- these wires are in contact with one another along a generatrix which remains the same over their entire length.
- each of the threads to be assembled is unwound from a double twist twisting machine operating as an unwinder, and the assembly is itself carried out by a twisting machine double twist operating in a conventional manner.
- the production, or productivity, expressed in number of twists per unit of time is, with this arrangement, equal to twice the speed of rotation of the assembly.
- each of the wires to be assembled is unwound from a single twist twisting machine, and, as before, assembly is ensured by a double twist twisting machine.
- the present invention generally relates to a provision which, while allowing the production of cables of satisfactory quality, in particular as regards a relative constancy of the impedance from one cable to another, advantageously requires, for its implementation, fewer rotating elements than the provisions previous, with, as a corollary, a production advantageously greater than that to which these lead.
- the untwisting of these son may for example be between 25% and 50% being preferably between 30% and 40%.
- twisting machine which, commonly known as horizontal lyre pairing machine , without necessarily the path of the wires being necessarily horizontal, is suitable for bringing together two cable wires without any individual twisting thereof, this twisting machine practicing, in addition to a first transmission coil, a lyre assembler in which a second transmission coil operates.
- the present invention firstly relates to a cabling process suitable for producing an at least partial twist cable, characterized in that, on the same production line, first a twist-free assembly station, to which the various necessary wires are assembled without any twist on themselves individually resulting in them, then a twisting station, to which, taken as a whole, the cable therefore formed by these son is subjected to at least one twist; it also relates to any cable installation using such a process.
- the cable installation according to the invention very simply implements, on the one hand, for the twist-free assembly station, a horizontal lyre auger, and, on the other hand, for the twisting station, a double twist twisting machine.
- the twist-free assembly station a horizontal lyre auger
- the twisting station a double twist twisting machine.
- only two rotating elements are used, namely the horizontal lyre pairing machine of the torsion-free assembly station and the machine twisting twist of the twisting station, and, if these two rotating elements all rotate at the same speed, the production of the assembly is equal to three times their rotational speed.
- this rate of untwisting can thus advantageously be easily varied, according to the requirements formulated by the interested parties.
- a voltage measurement device to which is controlled a braking device controlling the first transmission coil, and it is made so that the tension of the cable at the outlet of the assembly station without twisting is substantially equal to twice the tension of the wire at the outlet of this first transmission coil.
- FIG. 1 is a representation of a cable installation according to the invention ;
- Figure 2 shows, on a larger scale, the detail of Figure 1 identified by an insert II in this Figure 1;
- Figure 3 is an abacus corresponding to the operation of this cable installation;
- FIG. 4 is a more general block diagram of any cable installation according to the invention.
- Figures 1 to 3 illustrate, by way of example, the application of the invention in the case where it is simply a question of assembling together two wires f1, f2, the cable c to be produced being a simple pair.
- the cable installation 10 implemented for this purpose comprises, in series, on the same production line, first, a twist-free assembly station 1 1, suitable for joining together, without individual twist, the two wires f1, f2, then a twisting station 1 2, suitable for applying at least one twist to the assembly.
- the twist-free assembly station 1 1 comprises, in addition to a first transmission coil B1 from which the wire f1 is unwound, at least one bay 1 3, this bay 1 3 being formed in practice of 'An assembler 14 within which intervenes a second emission coil B2 from which the wire f2 is unwound. As regards the production of a single pair, only one bay 1 3 is provided.
- the assembler 14 of this bay 1 3 is a lyre assembler.
- the torsion-free assembly station 1 1 comprises, at its outlet, an assembly assembly 1 6.
- this assembly assembly 1 6 is formed, on the one hand, by a rocket 1 7, which has an axial input E2 for the wire f2 and at least one Entrance peripheral E1 for the wire f1, and of which all the outputs S1, S2 ... etc. are peripheral, being distributed circularly on the same circumference, in the manner of a committing plate, and, on the other hand, downstream of this rocket 17, of a die 1 8 common to all of the wires f1, f2 ... etc ...

- 1 7 has only one peripheral input E1 and only two outputs S1, S2.
- the assembly formed by the transmission coil B1, the bay 1 3 and the assembly assembly 1 6 constitutes what is commonly called a horizontal pairing machine with a PHL lyre. Since such a horizontal PHL lyre pairer is well known in itself, it will not be described in more detail here.
- N1 be its speed of rotation around its axis A1.
- the twisting station 1 2 comprises a collator which, in the embodiment shown, is a DT twist twisting machine.

- Tc3 be its number of twists in zone Z3 of this double twist DT twisting machine formed between the output of its lyre 1 9 and the take-up reel B3.
