Definitions

  • the present invention relates generally cabling machines of the kind implementing, for the realization of an electric cable comprising at least two pairs of insulated wires, on the one hand, for each of the pairs, suitable twisting means for twisting the two wires together intended to form such a pair, hereinafter referred to as simple convenience primary torsion means, and, on the other hand, for the set of pairs, means of torsion suitable for twisting together the various pairs, hereinafter referred to as simple convenience secondary torsion means (FR-A-2 147 951).
  • a taping station which allows to associate with each of the pairs a ribbon intended to wrap around it, in principle in propeller, to form the screen sought, a die of commettage, which presents, for the passage of the various pairs and their respective ribbons, as many holes as there are such pairs, and an assembly die, which presents, for the joint passage of all of these pairs, a piercing unique.
  • the step of assembling the pairs that is to say the pitch of the propeller that each of them forms within the electric cable, varies very widely, but is usually in the range of 15-20 times the diameter of this electrical cable.
  • the taping is necessarily done at the same pace.
  • the taping step is a relatively large multiple of the diameter, or, otherwise said, this taping step is particularly long compared to this diameter.
  • the ribbon applied is a metallic, or metallized, ribbon and therefore presents transversely a certain stiffness, in function, in particular, of its thickness.
  • the present invention generally has for object a provision to overcome in a very simple this difficulty.
  • this sector assembly takes place at a distance from the committing which, preferably, is at most equal to the half the step of a ribbon around a pair.
  • each of the holes of the committing process forms a convergent, to ensure by wrapping the corresponding pair with the ribbon itself associated with it.
  • the torsion means primary intervening at a distance from the axis of the assembly for take into account their own footprint and being followed by at least two pulleys to bring this axis closer to the matching pair, the taping station intervenes upstream one of these return pulleys.
  • the taping station ensures the installation of the ribbon along the same groove of the return pulley upstream of which he intervenes.
  • the ribbon associated with a pair advantageously extends parallel to it, which facilitates its wrapping around it in the corresponding drilling of this committing die.
  • an electric cable 10 comprising at least two pairs 11 of insulated wires 12, each of these pairs 11 being "screened", that is to say coated individually in a shielding screen 13.
  • the electric cable 10 to be produced has four pairs 11.
  • the wiring machine 14 ensuring, according to the invention, the realization of this electric cable 10, puts in work, in a manner known per se, on the one hand, for each of the pairs 11, torsion means 15, here called by simple convenience primary torsion means suitable for twisting together the two wires 12 intended to form such a pair 11, these wires 12 each being individually unwound from transmitting coils 16, and, on the other hand, for all of the pairs 11, torsion means 18, here called by simple convenience secondary torsion means suitable for twisting together the various pairs 11.
  • the means of primary torsion 15 are torsion means ensuring that this pair 11 an alternate wiring direction, in accordance with a provision commonly designated by the acronym "SZ"
  • these primary torsion means 15 are of the type covered by the German patent No 2 230 972 (& FR-A-2 189 829).
  • the torsion means primary 15 are followed by at least two idler pulleys 19, 20 allowing the pair 11 concerned to be brought closer to axis A of the assembly.
  • the secondary torsion means 18, meanwhile, are torsion means ensuring the electric cable 10 resulting in a constant sense of wiring.
  • These secondary torsion means 18 are, by example, double twist means, with rotating reception or single twist.
  • the cable electric 10 from these secondary torsion means 18 is received on a take-up reel 22.
  • the committing die 24 presents, in practice, as many holes 26 as there are such pairs 11, in species four, and these holes 26 are regularly distributed circularly around axis A of the assembly.
  • the assembly die 25 has a bore 27 single, and it extends along the axis A of the assembly.
  • the assembly line 25 intervenes in the immediate vicinity of the committing sector 24.
  • this distance D is zero, the entry 28 of the hole 27 of the assembly die 25 being immediately following exits 29 from holes 26 of the committing process 24.
  • the assembly line 25 is integral with the committing 24.
  • the assembly die 25 and the committing channel 24 can just as easily belong together with a single piece.
  • the assembly line 25 and the committing 24 can advantageously be carried by the same support, not shown.
  • the holes 26 in the commettage 24 converge jointly towards the axis A of the whole, and each of them forms a convergent itself, for perfect by itself, or even ensure, as well as will appear below, the coating of the corresponding pair 11 by the ribbon 13 'which is associated therewith.
  • the angle of inclination B of the holes 26 on the axis A of the assembly is between 8 and 15 °, for example being close to 12 °, and their convergence angle C, that is to say the angle-at the top of the cone they form, is between 10 and 20 °, being by example close to 15 °.
  • the face upstream 32 of the committing die 24, that is to say the face transverse of this committing die 24 on which is locate the inputs 33 of the holes 26, is globally frustoconical, so that, given their angle of inclination B on the axis A of the assembly, the axes of these holes 26 are substantially perpendicular thereto.
  • the bore 27 of the assembly line 25 is itself generally cylindrical, with a diameter which corresponds substantially to the diameter of the cable electric 10 to be formed, while being slightly higher than this one, but, on the side of its entry 28, by which it circumscribes, largely, and beyond, the outputs 29 of the holes 26 of the committing die 24 to avoid any catching at this level, this bore 27 locally forms a convergent largely rounded transverse profile.
  • the length L2 of the bore 27 of the assembly line 25 is a multiple of the length L1 of holes 26 of the committing die 24, measured according to axis A of the assembly.
  • this multiple is greater than two.
  • the industry of assembly 25 forms, radially projecting outwards, on the side of the outlet 34 of its bore 27, a flange 35.
  • the return pulley 19 most upstream intervenes as closely as possible primary torsion means 15, and, likewise, the die of commissioning 24 occurs as close as possible to the return pulley 20 furthest downstream.
  • the taping station 23 intervenes so that, at the entrance to the committing 24, the ribbon 13 'associated with such a pair 11 extends parallel to it.
  • the taping 23 occurs upstream of one of the deflection pulleys 19, 20, and, in practice, upstream of the return pulley 20 la further downstream, ensuring the installation of the corresponding 13 'ribbon along the same groove 36 thereof.
  • the bottom 37 of this groove 36 is flat, and on this bottom 37 come superimpose, on a little less than 90 °, the 13 'ribbon and the pair 11.
  • the ribbon 13 ′ is unwound from a emitting coil 38, and, after passing over a guide roller 39, it wraps the deflection pulley over a little more than 180 ° 20.
  • the ribbon 13 'associated with each of the pairs 11 accompanies this pair 11 parallel to it until the entry of the assembly into the corresponding bore 26 of the committing die 24, and, thanks to this drilling 26, it coats pair 11, as shown in dashed lines for one of them in FIGS. 4 and 5, and, in practice, the corresponding coating is done in a helix, at the pitch P of the next assembly.
  • each of the pairs 11 thus coated with a ribbon 13 ' is finds itself helixed with the others in favor of the assembly line 25, and with it the ribbon 13 'which the coating, which, on the one hand, leads to a helical twist of this ribbon 13 'with the corresponding pitch P, and what, else part, ensures the subsequent holding of the shielding screen 13 thus formed, preventing the ribbon 13 'constituting it to open up.
