Abstract
The present invention provides a method of making a tire bead (16) with a tape (10) composed of two parallel wires (12a, 12b) having a coating (28) of resilient elastomeric material and connected by a web (14). The tire bead (16) can be built by winding the tape (10) in side by side relation and in successive superposed layers of predetermined widths and with convolutions spanning superposed layers to provide the tire bead (16) of predetermined cross-sectional area.
Claims5
A method of making a tire bead comprising the step of:
- winding of convolutions of a tape in side by side relation and in successive superposed layers of predetermined widths to provide a tire bead of predetermined cross-sectional area, the tape being two spaced parallel wires each uniformly coated with a resilient elastomeric material and connected by a web of the elastomeric material, the web being sized so that the tape is sufficiently pliable to allow the tape to straddle successive superposed layers.
