A method and an apparatus for forming bead members (D), capable of improving the working efficiency by allowing switching to the bead members with different widths in short a time. The apparatus includes sector segments (24) having first sidewalls (61-64) of bead member forming grooves (72, 73), and arcuate members (51) arranged on the outer side of the sector segments (24), and having second sidewalls (68-71) of the bead member forming grooves (72, 73). The arcuate members (51) are axially moved by a changing means, to change the distance between the first sidewalls (61-64) and the second sidewalls (68-71) of the bead member forming grooves (72, 73). Thus, when bead members (D) of a different width (winding turns of bead element S) are to be formed, the width of the of the bead members bead member forming grooves (72, 73) can be changed easily, without requiring replacement of the sector segments (24).
