Definitions

  • the present invention relates to an improved design for a radial ply automobile tire, and more specifically to an improved apex for a radial ply automobile tire.
  • a conventional radial-ply automobile tire includes radial plies that are wrapped around two annular inextensible beads.
  • a green tire carcass (“green” meaning as yet uncured and still tacky) is built by sliding a green innerliner and radial ply over a tire "building drum” (or 'building mandrel”).
  • Two beads (each comprising a cable of steel filaments encased in green rubber) are then slid over the carcass, one at each side.
  • the portions of the plies that extend beyond the beads are then turned up around the beads, forming "turn-ups” .
  • the portion of the plies between the beads is expanded radially outward so as to contact the ply turn-ups.
  • the annular cross-sectionally triangular rubber filler bounded by the turned up ply and the bead is called an "apex" .
  • apexing machine adheres an annular triangular apex to an annular bead.
  • the bead, with the apex still adhering to it, is slid over the carcass on the building drum.
  • the plies are then turned up and expanded as mentioned above, so that the apex is surrounded by the bead from below and by the plies from the sides.
  • the apex In the "flat application of apex" method, the apex is circumferentially laid down onto the carcass while on the building drum.
  • the apex is laid down as a triangular strip of green rubber ("gum strip") lying horizontally on the carcass, next to the bead, so that one of its tacky long flat sides adheres to the tacky green carcass, and its short base is close to, and faces, the bead.
  • the apex's wedge profile swings around 90 degrees, and rests atop the bead, aligned vertically.
  • the choice of triangular dimensions and material properties of the apex affects the performance of the tire, such as tire weight, sidewall stiffness, handling, ride comfort, flexural heat, material fatigue, and tire life. For example, since the apex extends up much of the length of the sidewall, increasing the stiffness of the apex increases the stiffness of the sidewall, yielding less sidewall flexing and hence less flexural heat and material fatigue, but at the cost of a rougher ride. Increasing the apex's radial length (so that it travels farther up the sidewall) further stiffens the sidewall and improves handling, which is beneficial for "high performance" tires.
  • the "flat application of apex" method does not have the radial length limitation experienced by the pre-apexing method, because its apex is laid horizontally against the carcass. However, it does suffer from entrapped air which can cause internal delaminations.
  • pre-apexing is not suitable for making compound apexes, because the compound extrusion required for such an apex is complex to extrude and prone to deformation while standing vertical on the bead in the soft green state.
  • the "flat application of apex” method is not suitable for making compound apexes because increasing the number of apex layers increases process time and requires a more complex extruder in the building drum area.
  • Patent No. 4,934,431 in Figure 3, discloses a bead filler 6 (apex) disposed above a ring of bead wire 3 (bead) and a "bead reinforcing layer 8 disposed within the folded portion of the carcass 4 and extending about the bead wire 3" wherein the reinforcing layer 8 may be composed of cords of carbon fiber with a rubber latex adhesive.
