Definitions

  • the invention relates to an installation for manufacturing an assembly of wire elements.
  • a tire for heavy goods vehicles with a radial carcass reinforcement is known from the state of the art.
  • Such a tire comprises a radial carcass reinforcement anchored in two beads and surmounted radially by a crown reinforcement itself surmounted by a tread which is joined to the beads by two sidewalls.
  • the crown reinforcement comprises a working reinforcement, a hooping reinforcement, a protective reinforcement, and optionally, a triangulation reinforcement.
  • the relative arrangement of these reinforcements with respect to each other may vary.
  • the protective reinforcement is the radially outermost reinforcement
  • the working reinforcement is the radially innermost reinforcement
  • the hooping reinforcement being arranged between the protective reinforcement and the working reinforcement.
  • Each armature comprises a single or several layers.
  • Each ply comprises reinforcing elements arranged side by side parallel to each other. The reinforcing elements make an angle which varies according to the reinforcement to which the layer belongs.
  • Each reinforcing element comprises one or more assemblies of wire elements, each assembly comprising several single metal wires assembled together, either by cabling or by twisting.
  • the installation comprises supply means and individual preforming means for each wire arranged in a rotating nacelle arranged upstream of the assembly point of the wire elements together.
  • the heavier the feed and preforming means the more the nacelle must be dimensioned so as to mechanically resist the inertia generated by the mass of the assembly of the nacelle, the feed means and the preforming means. In order to limit this inertia, it is therefore necessary to work at relatively low speeds of rotation, which limits the productivity of the installation.
  • this step of preforming the wire elements does not make it possible to achieve high structural elongations.
  • the use of an assembly method using a step of preforming the wires makes it possible to obtain a structural elongation at most equal to 2.0% for the cable 3.26 described above.

  • each wire element being arranged upstream of the individual preforming means, no action is taken on the curvature of the wire elements obtained during and after the preforming step using the individual preforming means.
  • the individual preforming step taking place downstream of the individual twisting step the twisting cannot eliminate the helix subsequently created by the preforming.
