Definitions

  • the present invention relates to the field of the production of wire elements, called “cabled”, by assembly by twisting of several continuous strands, in particular of textile yarns.
  • the present invention relates more particularly to the application of such an assembly method to the manufacture of reinforcing wire elements which are intended to enter into the constitution of tires, in particular pneumatic tires for vehicles.
  • the strands are stored on input spools, from which each strand is unwound to an assembly point, at which said strand is interlaced with the other strand(s) to form a wired element, called " cable ".
  • the strands may have been previously subjected, before being unwound and assembled, to a twisting operation, in order to present a certain pre-twist around their axis.
  • a motorized drive device such as a capstan, which is placed between the input reel and the assembly point in order to give the strand in question a speed of predetermined advance.
  • the wire element is itself driven, downstream of the assembly point, by a motorized output reel, on which said wire element is wound as it is manufactured.
  • a slider which is mounted to slide freely on a ring, coaxial with the axis of rotation of the output spool. output, and through which the wired element passes before joining the coil.
  • the rotation of the coil generates traction on the wired element, which in turn induces a stress on the slider which, by reaction, travels in rotation along the ring and thus causes a twisting movement which generates the intertwining of the strands at the assembly point.
  • the behavior of the slider is sensitive to the degree of filling of the output spool, insofar as the orientation of the wired element which leaves the slider to join the spool varies depending on whether the output spool is very sparsely filled , in which case the wire element, which has a small turn diameter, is oriented quasi-radially with respect to the axis of the coil, and therefore quasi-radially with respect to the axis of the ring which carries the slider , or depending on whether the output coil is on the contrary filled, in which case the wire element, which has a large turn diameter, is oriented almost tangentially to the outer perimeter of said coil.
  • the objects assigned to the invention therefore aim to remedy the aforementioned drawbacks and to propose a new method and a new installation for manufacturing a wire element by interlacing strands, the implementation of which is facilitated, and which has improved robustness and good reproducibility.

  • the implementation of a regulation by the tension of one or more strands, rather than by speeds, therefore makes it possible to finely control, and in a reproducible manner, the properties of the fabricated wire element.
  • the method according to the invention is therefore particularly robust and reproducible.
  • the method makes it possible to simultaneously control one strand in tension and the other strand in speed.
  • the invention makes it possible to select, by means of a selector, for at least one of the strands or even for each strand of the wired element, a voltage control or a speed control, which in particular offers multiple possibilities. combinations when searching for new wireframe elements with particular properties.
  • the interlacing which occurs at the assembly point makes it possible in a way to "freeze" the properties which have been conferred on the wire element thanks to the tension and/or speed servo-controls chosen for the different constituent strands of said wired element, and therefore to substantially retain the properties and advantages procured by the specific combination of these chosen controls.
  • the method according to the invention is perfectly applicable to the manufacture of a wire element involving different lengths of strands from one strand to another, and in particular to the manufacture of so-called "covered" wire elements.
