ABSTRACT:
A method of producing an annular bead core assembly for a pneumatic tire from a plurality of wires of substantially rectangular cross-section, wherein the wires are formed into a plurality of plies. The wires of each wire ply then are arcuately deformed in a direction substantially perpendicular to the desired plane of the annular assembly when made but in a direction which will be towards the inner side of the tire when completed, each arcuate deformation yielding an arc having a constant radius. The arcuately deformed wire plies thereafter are wound on a tapered support to form the assembly.
