Definitions

  • the present invention relates to processes and devices for manufacturing three-layer metal cables, in particular of M + N + P construction, which can be used in particular for reinforcing rubber articles such as tires.
  • a radial tire comprises in known manner a tread, two inextensible beads, two flanks connecting the beads to the tread and a belt circumferentially disposed between the carcass reinforcement and the tread.
  • This carcass reinforcement is constituted in known manner by at least one ply (or “layer”) of rubber reinforced by reinforcement elements (“reinforcements”) such as cords or monofilaments, generally of the metal type in the case of pneumatic tires for industrial vehicles carrying heavy loads.
  • steel wires for the reinforcement of the above carcass reinforcements, use is generally made of steel wires ( “steel cords”) called “layers” ( “layered cords”) consisting of a central layer or core and one or more layers of concentric threads arranged around this core.
  • the most used three-layer cables are essentially M + N + P construction cables, formed of a core of M wire (s), M varying from 1 to 4, surrounded by an intermediate layer of N wires, N typically ranging from 3 to 12, itself surrounded by an outer layer of P son, P typically ranging from 8 to 20, the assembly may be optionally shrunk by an outer hoop thread wound helically around the outer layer.
  • M wire M varying from 1 to 4
  • N typically ranging from 3 to 12
  • P typically ranging from 8 to 20
  • Such a cable is described in the application JP2007303044 .
  • We know of the document JP2006283249 a corresponding manufacturing method of such a cable comprising a step of balancing the twists
  • these layered cables are subjected to considerable stresses during the rolling of the tires, in particular to repeated flexures or variations of curvature inducing at the level of the strands of friction, in particular as a result of the contacts between adjacent layers, and therefore of wear, as well as fatigue; they must therefore have a high resistance to phenomena known as "fatigue-fretting".
  • this material penetrates all the spaces between the wires constituting the cables. Indeed, if this penetration is insufficient, then empty channels or capillaries are formed, along and inside the cables, and corrosive agents such as water or even oxygen in the air, likely to to enter the tires for example following cuts in their tread, walk along these empty channels into the carcass of the tire.
  • corrosive agents such as water or even oxygen in the air, likely to to enter the tires for example following cuts in their tread, walk along these empty channels into the carcass of the tire.
  • the presence of this moisture plays an important role in causing corrosion and accelerating the degradation processes above (phenomena known as "fatigue-corrosion”), compared to use in a dry atmosphere.
  • one of the essential characteristics is that a sheath consisting of a rubber composition covers at least the intermediate layer consisting of M son, the core (or unit wire) of the cable may itself be covered or not rubber. Thanks to this specific architecture, not only an excellent penetrability by the rubber is obtained, limiting the corrosion problems, but also the fatigue-fretting endurance properties are significantly improved compared to the cables of the prior art. The longevity of the tires and that of their carcass reinforcement are thus very significantly improved.
  • these three-layer cables are obtained in several steps which have the disadvantage of being discontinuous, firstly by producing an intermediate cable 1 + M (in particular 1 + 6), then by sheathing via an extrusion head of this intermediate cable, finally by a final operation of wiring the N (in particular 12) son remaining around the core thus sheathed, for forming the outer layer.
  • an intermediate cable 1 + M in particular 1 + 6
  • an extrusion head of this intermediate cable finally by a final operation of wiring the N (in particular 12) son remaining around the core thus sheathed, for forming the outer layer.
  • N in particular 12
  • each wire of the inner layer is individually sheathed by passing through a bath of a liquid solution comprising a liquid rubber composition.
  • This method of the invention makes it possible to manufacture, preferably in line and continuously, a three-layer cable which, compared to the three-layer gummed in situ cables of the prior art, has the significant advantage of having a reduced quantity. filling gum, which guarantees a better compactness, this gum being further distributed evenly inside the cable, inside each of its capillaries, thus conferring on it a further improved longitudinal impermeability.
  • any range of values designated by the expression "between a and b" represents the range of values from more than a to less than b (i.e. terminals a and b excluded) while any range of values designated by the term “from a to b” means the range from a to b (i.e., including the strict limits a and b).
  • An essential feature of the above method is to use a twisting step both for assembling the second layer (C2) around the first layer (C1) and for assembling the third layer (C3) around the second layer (C2).
  • the diameter d 0 (or total overall diameter) of the core (C1) is preferably in a range of 0.08 to 0.50 mm, this core may consist of a single wire or several son previously assembled between them by any known means, for example by cabling or more preferably by twisting.

  • this core (C1) is first sheathed by uncrosslinked filling rubber (in the green state), provided by an extrusion screw at an appropriate temperature.
  • the filling rubber can thus be delivered at a fixed point, unique and compact, by means of a single extrusion head.
  • the extrusion head may comprise one or more dies, for example an upstream guide die and a downstream die calibration. It is possible to add continuous measurement and control means of the diameter of the sheathed core, connected to the extruder, as well as means for controlling the centering of the core in the extrusion head.

  • the isoprene elastomer is preferably natural rubber or synthetic polyisoprene of the cis-1,4 type. Among these synthetic polyisoprenes, polyisoprenes having a content (mol%) of cis-1,4 bonds greater than 90%, more preferably still greater than 98%, are preferably used.
  • the isoprene elastomer may also be associated with another diene elastomer such as, for example, an SBR and / or BR elastomer.
  • the filling rubber may contain one or more elastomer (s), especially diene (s), the latter or they may be used (s) in combination with any type of polymer other than elastomer.
  • the filling rubber is preferably of the crosslinkable type, that is to say that it comprises by definition a crosslinking system adapted to allow the crosslinking of the composition during its cooking (ie, its hardening and not its melting); thus, in such a case, this rubber composition can be described as infusible, since it can not be melted by heating at any temperature.
  • the system for crosslinking the rubber sheath is a so-called vulcanization system, that is to say based on sulfur (or a sulfur-donor agent). ) and at least one vulcanization accelerator.
  • the invention also applies to cases where the filling gum is free of sulfur and even of any other crosslinking system, it being understood that it could be sufficient, for its own crosslinking or vulcanization, the crosslinking or vulcanization system already present in the matrix of rubber that the cable of the invention is intended to strengthen, and likely to migrate by contact of said surrounding matrix to the filling rubber.
  • the filling rubber may also comprise all or part of the usual additives intended for tire rubber matrices, such as, for example, reinforcing fillers such as carbon black or silica, antioxidants, oils, plasticizers, anti-eversion agents, resins, adhesion promoters such as cobalt salts.
  • reinforcing fillers such as carbon black or silica, antioxidants, oils, plasticizers, anti-eversion agents, resins, adhesion promoters such as cobalt salts.

  • Torsion balancing is meant here in a known manner the cancellation of the residual torsional torques (or detorsional springback) exerted on each wire of the cable in the twisted state, in its respective layer.
  • Torsion balancing tools are known to those skilled in the art of twisting; they may consist for example of “trainers” and / or “twisters” and / or “twister-trainers” consisting of either pulleys for twisters or small diameter rollers for trainers, pulleys or rollers through which circulates the cable in a single plane or preferably in at least two different planes.
