Abstract
A method of producing at least two single wire tyre bead cores comprising drawing off at least two bead wires from separate coils (20) of wires, passing the wires through wire processing means (23) to coat the drawn-off wires with rubber material, passing the rubber-coated wires through first festooner apparatus (24) and subsequently winding the rubber-coated wires on a former (36) to create at least two single wire tyre bead cores on the former. Before the wires are passed through the first festooner apparatus (24) they are joined together in the wire processing means (23). The joined together rubber coated wires are split (at 30) after passing through the first festooner apparatus (24) and, after being split, are passed through second festooner apparatus (31) before being wound on the former (36). The invention also relates to apparatus for producing at least two single wire tyre bead cores.
