Abstract
A bead ring for a tire mold includes a plurality of concentric rings, wherein at least two adjacent concentric rings form an interface having a circumferential seam. The circumferential seam is configured to receive airflow from an interior of the tire mold, and the circumferential seam is in fluid communication with an air chamber located radially exterior of the circumferential seam.
Claims18
A tire mold, comprising:
- a tread ring having tread forming elements disposed thereon;
- two sidewall members adjacent to the tread ring, wherein the sidewall members are selected from the group consisting of plates and rings;
- a plurality of concentric bead rings,
- wherein at least two adjacent concentric bead rings form a bead ring interface having a circumferential seam,
- wherein the circumferential seam is configured to receive airflow from an interior of the tire mold,
- wherein one of the concentric bead rings is adjacent to one of the sidewall members,
- wherein one of the concentric bead rings is made up of a plurality of adjacent radial sections, and
- wherein the radial sections have partially sinusoidal ends that intermesh with the partially sinusoidal ends of adjacent radial sections;
- and
- an air chamber located radially outside of the circumferential seam and fluidly connected to the circumferential seam.
