Claims
- 1. A method of forming a tire component, comprising:
- producing an apexed bead ring having a plurality of bead wire laterally spaced apart from one another transversely of the lengthwise extent of the apexed bead ring and an integrally formed apex portion extending laterally on one side of the plurality of bead wires;
- winding the apexed bead ring onto itself about a winding axis parallel to the lateral extent of the apexed bead ring to form a bead hoop with the apex portion of the apexed bead ring being lapped upon itself to form one edge of the bead hoop;
- providing a tire carcass ply disposed in cylindrical form about a carcass ply axis;
- placing the bead hoop on the tire carcass ply in an initial bead hoop orientation in which the one edge of the bead hoop formed by the lapped apex portion extends in a substantially axial orientation relative to the carcass ply axis and the bead wires of the bead hoop extend generally circumferentially adjacent the tire carcass ply; and
- manipulating the tire carcass ply relatively about the bead hoop to create a tire component formed of the bead hoop and the tire carcass ply turned around the bead hoop, the step of manipulating including manipulating the tire carcass ply to displace the apex portion of the bead hoop from its substantially axial orientation to a substantially radial orientation in such a manner that only the apex portion is reoriented while the bead wires of the bead hoop remain in their same initial orientation.
- 2. The method according to claim 1 wherein the step of producing an apexed bead ring includes shaping the apex portion of the apexed bead ring in a triangular cross sectional shape as viewed in a plane transverse to the lengthwise extent of the apexed bead ring.
- 3. The method according to claim 1 wherein the step of producing an apexed bead ring includes depositing rubber of a selected durometer hardness around the plurality of bead wires and forming the apex portion from a rubber having a durometer hardness greater than the selected durometer hardness of the rubber deposited around the bead wires.
