Method and apparatus for making an apexed bead ring |
摘要 |
<p>A method of making an apexed bead for a tire comprises the steps of providing a supply of rubber and a supply of bead wire. The rubber is extruded around at least one bead wire. An apex leaf projects from the rubber extruded around the bead wire to form a bead ribbon. The apex leaf extends in a direction laterally from the extent of the bead wire and is located between a pair of planes which are coextensive with opposite major side surfaces of a bead portion of the bead ribbon. The bead ribbon is wound spirally about itself to form a bead. Radially adjacent apex leafs contact one another to form an integral apex extending laterally from the bead. <IMAGE></p> |
